1 General information
Ekomilk Spectra is designed for fast and cost effective control of milk quality - de-
tecting adulterants (ammonium sulfate, urea, etc.) and milk parameters (Fat, Solids
Not Fat, etc.). The mid-infrared spectral module allows for detection of adulterants
and their concentration without the use of chemicals and the well established ultrasonic
module measured the milk parameters. Ekomilk Spectra hybrid milk analyzer, uses
two analytical methods, combined in the convenience of one simple instrument - in-
frared spectroscopy in the mid-infrared region, and ultrasonic measurement.
Mid-infrared spectral analysis
Different species in a sample have unique absorption patterns of the infrared light.
Based on those patterns and how pronounced they are, the species (in our case adul-
terants) and their concentrations can be identified.
Ultrasonic measurement
Ultrasonic material analysis is based on a simple principle of physics: the motion of
any wave will be affected by the medium through which it travels. Thus, changes in
one or more of four easily measurable parameters associated with the passage of a high
frequency sound wave through a material - transit time, attenuation, scattering and fre-
quency content - can be correlated with parameters in milk.
Why not using only infrared technology for measurement of all parameters?
The short and simple answer is that this will increase the cost for the user 5-15 times
without adding real value for the purpose of the device.
The longer answer is that, to measure all parameters of interest, a much larger portion
of the spectrum needs to be measured and analyzed. However in order to do that either
much more sophisticated mechanics and optics or more sensors are necessary. This
will drastically increase the price and also make the device less suitable for a field
instrument.

3 Safety measures
1. Read carefully and strictly follow the instructions described in this user’s guide.
2. Under no circumstances you should try to repair Analyzer’s power lead by your-
self.
3. EkoZero concentrate liquid, used for the infrared module is a chemical that is
considered hazardous which in case of direct contact may cause severe eye irri-
tation or even serious eye damage. It is also considered the that liquid has acute
oral toxicity.
4. The cleaning set for the ultrasonic module (EkoDay and EkoWeek) contains base
and acid, and is considered to have corrosive behavior. Use protection - gloves
and glasses, when preparing the cleaning solutions with these chemicals and pay
more attention when you work with them.
5. Do not eat, drink or smoke when using the concentrates for preparing cleaning
and zeroing solutions (EkoZero, EkoDay, EkoWeek).
3

6. EkoClean is a powder substance, which in case of direct contact can irritate res-
piratory organs and eyes.
7. Wear protective gloves/protective clothing/eye protection/face protection.
8. If by accident there is a direct contact the user should take these precautions:
•After inhalation: Supply fresh air; consult doctor in case of complaints.
•After skin contact: Rinse skin with running water thoroughly.
•After eye contact: Rinse opened eye cautiously with water for several min-
utes. Remove contact lenses, if present and continue rinsing. Immediately
call a poison center or doctor/physician.
•After swallowing: Immediately call a poison center or doctor/physician.
4 Method of work
1. Place vertically the Analyzer on a table or any other flat surface.
2. Connect the Power Supply (Model AC/DC-CL-DT 12/10) to the power supply
outlet ”In 12 V DC” on the Power Supply Panel and to the mains socket.
Attention: Before start working with the device make sure all the prepara-
tion work is done.
3. Preparation of the EkoZero solution for zero setting and cleaning (Infrared only)
The EkoZero concentrate is a liquid. Before preparing the work solution from
the concentrate, check the shelf life label on the bottle and follow the instructions
to prepare the solution. Dissolve contents - 50 ml in 5 L deionized (or distilled)
water or 10 ml in 1 L ( 0,01 %). It’s recommended to use the EkoZero solution
within 6 months from preparation.
NOTE: Store the prepared liquid in a cool place.
4. Place the mugs for cleaning solutions below the pumps of the infrared and ultra-
sonic modules(see section 7 for more information ).
5. Check if all measuring parts are in place.
6. Check if the filter is in place and clean it if necessary.
7. Switch on the analyzer.

8. Warming up
From a cool start after switching on the device it will take a few minutes for the
modules to warm up. Status indicator in the top left corner on the main menu
shows the progress in percentage. When the warming up is finished the status
indicates ”Ready” (Figure 1).
Figure 1: Status: Ready
9. Clean the two modules (IR with EkoZero solution, US with water).
10. ”Zero Procedure” (for the infrared module) - see more in section 7.
11. Start measurement (IR, US, Combined IR + US)
Explanation: When working with the ultrasound module, it is recommended to
pre-fill the system with milk. This can be done in two ways. The first way is to
perform cleaning procedure, but instead of water/cleaning solution the cleaning is
with milk. The second way is to measure a dummy sample (without considering
the reported result). The purpose of these actions is to fill the system with milk
for a more accurate result.
12. Cleaning
In the end of the working day clean the analyzer well, following the instructions
in section 6.
5 Milk samples requirements
1. Mix the milk before measurement by shaking it gently 5 times, without making
foam and air bubbles.
2. Before measurement, make sure that the temperature of the milk sample is be-
tween 15-25°C. When working with the ultrasonic module the sample tempera-
ture should be below 38°C, otherwise an error will occurs - HOT SAMPLE.
3. Put the milk sample in a ultrasonic bath for a few seconds - maximum a minute,
according to the degree of aeration.

6 Cleaning procedure
This section is to give directions for daily and periodical cleaning of milk analyzers
Ekomilk in order to assure their long life and proper functioning. Both modules must
be cleaned - infrared and ultrasonic. The analyzer should not stay for more than 30
minutes with milk.
Attention: It is very important to note here that the cleaning solutions for the infrared
and the ultrasonic modules are different. The cleaning solution for the ultrasonic mod-
ule can damage the infrared module. That is why the cleaning is performed in two
consecutive steps - first the one module is cleaned with the respective cleaning solution
and then the other module is cleaned. The order of cleaning is not important.
6.1 Infrared module cleaning
Ekomilk Spectra cleaning procedure works on a reversal principle to prevent problems
with cuvette clogging.
NOTE: Instructions for preparing EkoZero solution are on the packaging label of the
concentrate, also described in the section 4.
Clean the infrared module, following the steps below:
• the mug for waste milk is placed under the infrared module input.
• the mug for cleaning liquid EkoZero is placed under the IR peristaltic pump.
Figure 2: Cleaning
• when the <Clean IR>button is pressed - the system will request from the operator
to load the cleaning solution. In the case of infrared module cleaning the cleaning
solution is the same as the zero setting liquid - EkoZero liquid. When finish with
loading the cleaning solution and press ”OK” the pump will start rotates in the
opposite direction of the measurement. The cleaning solution passes from right
to left and falls into the mug for waste milk.
6

Figure 3: Clean IR
Full infrared cleaning
The IR module requires additional cleaning. It is recommended to be performed every
14 days, if necessary more often. It is also used in cases when the device will not
be used for a long time (more than a week). For this purpose is use EkoClean (it is
delivered in the form of granules in 2 packages 18 grams each).
Instruction for preparing 500 ml working solution (3.5%):
Take a transparent, non-sparkling 500ml water bottle with deionized water (or distilled
water) and warm it up to about 30-35 °C. Then pour the 18 grams EkoClean package
into the bottle. Stir the mixture up to complete dissolving and then cool it down to
15-25 °C.
Note: The 3.5% EkoClean solution is good for use up to 6 month after preparation if
the container is properly closed after every use. The EkoClean solution should be stored
at room temperature. If the solution is stored below 14 °C, it will become an opaque
and white gel. In that case, before using the solution, please warm up the solution above
30 °C to become transparent again.
Start IR cleaning and after the procedure finish, leave the device for at least 24 hours
without get out mugs (IR module must be leaved full with EkoClean solution). Af-
ter that, with the rest of EkoClean in the cleaning solution mug, start the IR cleaning
procedure once more, followed by a final cleaning - fill an empty cleaning mug with
deionized water (35-40 ml) and start required number of IR cleaning procedure (5-6 IR
cleaning procedures) - figure 4.
Figure 4: Clean IR with deionized water
7

6.2 Ultrasonic module cleaning
Cleaning the ultrasonic module requires more time than cleaning the infrared module
because different solutions are used to maintain the ultrasonic sensor in good condition.
The cleaning of the ultrasonic module is similar to the cleaning of the infrared module:
• the mug for waste milk is placed under the ultrasonic module input.
• the mug for cleaning solution is placed under the US peristaltic pump.
Figure 5: Cleaning
• when the <Clean US>button is pressed, the pump starts to rotate in the opposite
direction of the measurement, the cleaning solution/water passes from right to
left and falls into the mug for waste milk.
* the cleaning solution for the US module cleaning should be considered accord-
ing to the type of cleaning (daily or periodic).
Figure 6: Clean US
• After cleaning procedure, the ultrasonic module system is filled with air and there
should be no cleaning solution or water residues, the amount of solution/water in
the mug for cleaning solution is adjusted to the pump revolutions, so in the end
of the cleaning procedure the mug stays empty and the pump should suck only
air. Do not add extra solution/water in the cleaning solution mug under the US
pump.

Methods for daily and periodic clean of the Ekomilk Spectra
analyzer’s ultrasonic module
1. DAILY CLEANING
Daily cleaning is required when:
• The interval between two consecutive measurements is more than half of
one hour.
• The daily job is finished.
1.1. Cleaning out when the interval between two consecutive measurements
is more than half an hour.
Steps:
1.1.1. Fill the mug for cleaning solution (below the US peristaltic pump) with
clean and warm, but not hot, water (40°C-60°C). On the input of the ul-
trasonic module place the mug for waste milk, press the button <Clean-
ing US>, cleaning starts immediately.
1.1.2. Remove the mug and throw away the muddy water. Repeat this proce-
dure several times until clean water comes out from the Analyzer.
1.2. Cleaning out at the end of a working day.
This procedure prevents formation and collection of fat and ”Milk stone”
deposits into the sensor. Milk stone consists of milk solids, calcium, magne-
sium, iron, sulfates, etc. Milk and water mineral deposits become hardened
and layered on the sensor and vinyl pipes inner surfaces, which contact with
milk and disturbs the milk analyzer work. Cleaning will be effective if a
reagent which attacks the ”milk stone” is used. We recommend EkoDay to
be used as a daily cleaning solution.
Preparation of EkoDay working solution:
Dissolve 2 g of powder detergent EkoDay in 100 ml distilled or deionized
water. The solution can be used within 7 days after preparation.
Take care this solution does not contact your eyes or skin!
Attention! Use only EkoDay working solution as a cleaning agent. The
EkoDay concentrate can damage your analyzer!
Steps:
1.2.1. First clean the analyzer with pure water as it is described in procedure
1.1. (see above).
Attention! Always clean analyzer with pure water before using the
cleaning agent. Using cleaner EkoDay without first cleaning an-
alyzer for removing the fats and proteins will result in fixing the
”milk stone” to the surface.
1.2.2. Fill the cleaning solution mug with cleaner EkoDay (25°C-40°C), place
the mug for waste milk on the input of the US module. Press the button
<Cleaning US>, cleaning starts immediately. Make 5 cycles.
9

1.2.3. Fill the cleaning solution mug with alkaline clean water, press the but-
ton <Cleaning US>. Make 5 cycles. It’s important to remove all the
residues from the cleaning solution EkoDay!
2. PERIODICAL CLEANING PROCEDURE
To ensure a good work of the Milk Analyzer it is advisory to clean the device
at least once a week strictly performing underwritten procedure. This procedure
uses acid cleaner EkoWeek as a periodical cleaning solution.
Preparation of EkoWeek working solution:
Dissolve 1.8 g of powder detergent EkoWeek in 100 ml distilled or deionized
water. The solution can be used within 30 days after preparation.
Take care this solution does not contact your eyes or skin!
Attention! Use only EkoWeek working solution as a cleaning agent. The
EkoWeek concentrate can damage your analyzer!
2.1. Perform the daily cleaning first.
Attention! Make sure that the analyzer is properly cleaned with pure
water before going on to the next item of the procedure. Mixing both
cleaning solutions- alkaline EkoDay and acid EkoWeek will result in
forming ”milk stone”.
2.2. Fill the cleaning solution mug with solution of the acid cleaner EkoWeek(25°C-
40°C), place the mug for waste milk on the input of the US module. Press
the button <Cleaning US>, cleaning starts immediately. Make 5 cycles .
2.3. Open the top cover by pressing its left side - Figure 7 - step 1.
2.4. Remove the plug as it is shown on the - Figure 7 - step 2.
2.5. Insert the plunger instead of the plug Figure 7 - step 3.
2.6. Fill the measuring mug with clean and warm, but not hot, water (40°C-
60°C), dip the tube (sucker) into the water and place the measuring mug on
the Ekomilk working surface.
Move up and down the plunger several times. Remove the mug and throw
away the water. Fill the mug with clean and warm water and repeat this step
4-5 times - step 3.
2.7. Take the plunger out of the hole. Wait until all water comes out. Insert the
plunger again and press it to the bottom.
2.8. Remove the measuring mug and move the plunger out. Put the plug firmly
and close the top cover.
2.9. Done.
Note: During the daily and periodic cleaning of the analyzer, it is not desir-
able to use ”solid” (high salt) water. The water used for cleaning should be
”soft” (low in salt), and it is best to use distilled or deionized water.

Figure 7: Hand-cleaning
7 Zero procedure
The ”zero procedure” must be performed at the beginning of the working day and on
every hour during the day. This procedure is necessary to account for imperceptible
changes in the environmental conditions of the measurements and their compensation.
Failure to set to zero may adversely affect measurement accuracy. The analyzer
automatically warns of the need to perform a new procedure through the message ”Zero
Required!”.
The measuring mug (25ml) is filled with EkoZero solution, the mug for cleaning
liquid under the IR pump is empty (otherwise it will overflow).
Figure 8: Zero
To begin the procedure press the <Zero>button in the main menu(Figure 9). A new
window opens (see Figure 9a) with signalization to load zero solution in the measuring
mug. When the solution is loaded press <OK>. The zero setting starts and a progress
bar indicates the state of the procedure (Figure 9b). After the zero is done successfully,
in the right side of the button <Zero>appears a timer, which indicates the reminding
time to the next zero procedure (<Zero 1:00>, Figure 9c), so after 1h 00min the zero
will be expired. When this happens the timer disappear and a new zero procedure should
be done.
11

Note: The first sample after zeroing should be discarded, so we recommend to
make two measurements with the first milk!
(a) Load zero solution (b) Zero (c) Zero 1:00
Figure 9: Zero procedure
8 Milk analysis
Since Ekomilk Spectra is a hybrid analyzer using infrared technology for adulterant de-
tection and ultrasonic for standard milk parameters measurement, it can make complex
measurements using both modules, or it can be set to only use either the infrared or the
ultrasonic module for measurement. So if there is a problem with one of the modules
the analyzer can continue working with the other module.
8.1 Position of components and work
Position when using the infrared module:
• place the measuring mug, filled with sample on the Ekomilk Spectra’s working
surface.
• fill the mug for cleaning solution, under the IR pump with EkoZero solution.
Work of infrared module:
Attention: Before the first measuring, the infrared module is filled with cleaning/zeroing
solution - EkoZero. This is done during cleaning procedure (Clean IR) and zero proce-
dure (see section 6 and section 7).
When the measurement starts, the infrared module’s peristaltic pump takes a sample
of milk (yellow arrows, figure 10) that pushes the cleaning solution into the mug under-
neath the infrared pump. The IR pump rotates normally (from left to right). When the
sample is analyzed in the cuvette, the IR peristaltic pump reverses (from right to left),
and pushes back the analyzed milk in the measuring mug, while at the same time refills
the system with cleaning solution EkoZero (blue arrows, figure 10). The returned milk
sample should not be used again, because is mixed with the cleaning solution EkoZero.
Note: During IR measuring the mug for cleaning solution should be always filled
with EkoZero solution, otherwise the IR peristaltic pump will take air, this air will pass
into the system, respectively in the cuvette. When work properly the cleaning solution
EkoZero in the mug for cleaning solution should stay clear, without milk contamination.
12

Figure 10: Measurement
Position when using the ultrasound module:
Ultrasound measurement is similar to infrared. The difference is that the mug for clean-
ing solution under the US peristaltic pump should be empty. Here the use of the mug
for cleaning solution is for safety reasons. If there are drops of milk or cleaning solution
left in the system, they will fall into the mug.
Position of the components: (Figure 11)
• place the measuring mug, filled with sample on the Ekomilk Spectra’s working
surface
• place the empty mug for cleaning solution under the US peristaltic pump
Work of ultrasound module:
When initiating a measurement, the peristaltic pump on the ultrasound module takes a
sample of milk (a yellow arrow, Figure 11), which fills the ultrasonic sensor. In the end
of the measurement, the peristaltic pump returns the measured milk in the measuring
mug, while the ultrasonic sensor remains filled with air (blue arrows, Figure 11).
Figure 11: Measurement
13

8.2 Start measurement
To initiate a measurement press the <Measurement>button from the main menu (Fig-
ure 12).
Figure 12: Main menu
A new window pops up asking for the measurement configuration (Figure 13). The
main thing here is to select what modules of the hybrid analyzer to be used for the
measurement process. To use only the infrared or the ultrasound the check in the corre-
sponding check box must be ticked. To use both infrared and ultrasound simultaneously
for complex measurement both check boxes should be marked. Double-check button is
available for infrared measurement. His role is to recheck the concentration of adulter-
ants and show it more accurately.
The configuration windows (Figure 13) will appear every time a new measurement is
performed. That can be annoying and unnecessary. To skip this step the ”Remember”
check box should be ticked in the lower right corner of the window.
Figure 13: Measurement configuration
By clicking the <OK>button the measurement starts.
Resetting: In the main menu under <Measuring>button a configuration text should ap-
pear in a gray box. To clear the setting just press the text, in our case <Buffalo><US>.
A message asking you to delete measurement configuration will pop up, Figure 14.
14

Figure 14: Resetting configuration
After the measurement finishes successfully a window appears with measured milk
parameters and adulterants if any detected (Figure 15, 17). If a substantial volume of
unknown adulterant is detected - you will see ”Abnormal sample”.
Figure 15: Measurement with infrared
Figure 16: Measurement with ultrasound
Figure 17: Measurement with infrared and ultrasound

If the adulterant does not indicate what it is (for example - an ammonium compound),
you can click on the yellow rectangle and see the adulterant and the probability of it
being present in the current sample (Figure 18).

The conception for data transfer from Spectra to PC, using of Local Area Network
(LAN), includes few steps and ways to download ready data in convenient format
(CSV).
1. Connect PC and Spectra in LAN
a) To connect both units, PC and Spectra, in LAN it needs except patch cord
(UTP/STP cable) and an USB to Ethernet adapter because Spectra does not
have inbuilt LAN adapter. Spectra got 4 available USB ports. All of them
are appropriate to plug USB/Ethernet adapter. Next figure shows how to
connect units in LAN:
