4.1 General description
The Alfa Laval Toftejorg SaniJet 20 is a tank cleaning machine intended for industrial use in closed tanks for processing storage
and transportation. There is a broad range of application areas within pharmaceutical, food and chemical industries.
The Alfa Laval Toftejorg SaniJet 20 is a hygienic cleaning device of the rotary jet head type for permanent installation that provides
a 360° indexed cleaning pattern. Provided it is installed in an upright position, the Alfa Laval Toftejorg SaniJet 20 is completely
self-cleaning and self-draining, and it has an integrated self-cleaning down pipe (patent pending). The drive mechanism is located
outside the tank or process equipment, leaving a minimum of parts to be submerged into the product. All product contact
surfaces are AISI 316/316L, duplex SAF 2205, Ti, Hastelloy C22/C276 stainless steel and USP Class VI and FDA approved
polymer materials such as PEEK, EPDM, Viton and FFKM.
No threads or screws have been used in the product contact areas.
The cleaning device is lubricated by the cleaning media. No oil, grease or other lubricants are used.
The Alfa Laval Toftejorg SaniJet 20 is available in media driven or air motor driven versions. The air motor driven version is
equipped with a magnetic clutch providing a leakage-proof transmission and provide an effective drive for low flow machines
in rough environments. The air motor has variable speed in order to adjust cleaning intensity. The media version is covered by
Instruction Manual IM-TE91A792.
The Alfa Laval Toftejorg SaniJet 20 is designed for use in pharmaceutical, biotechnological, food and dairy processing applica-
tions. Tanks and vessels between 0.5-30 m3(130-8,000 US gallons). The design makes the Alfa Laval Toftejorg SaniJet 20
especially well suited when processing high viscous, foaming or thixotropic products and in chemical processing applications,
where product cross contamination is unacceptable and must be avoided.
For use in explosive hazard zones the ATEX/IECEx version can be used, provided it is installed according to safety instructions
in local regulations.

4.2 Functioning
Alfa Laval Toftejorg SaniJet 20 consists of 3 main parts: The Drive unit with flow inlet and the Base housing placed outside the
tank, and inside the tank: the Down pipe with the rotating Outer tube and the Cleaner unit.
The flow of the cleaning fluid passes from the inlet through the Base housing,
through the Down pipe, into the Cleaner head and out through the Nozzles. The
Outer tube of the Down pipe is rotably suspended on a Stationary shaft with a Ball
bearing inside the Outer tube. The Drive mechanism rotates the Outer tube with
the Cleaner unit around the vertical axis. Via a set of Bevel gears on the Stationary
shaft and the Cleaner head, the Cleaner head with the Nozzles is simultaneously
rotated around the horizontal axis in a fixed relation thus moving the nozzles and
the jets 360°around in the tank making a pre-set indexed cleaning pattern.
The Alfa Laval Toftejorg SaniJet 20 utilises the patented “Golden Section” cleaning pattern. The distance between the tracks
of the jets ensures an efficient removal of remaining product from the tank surface right from the beginning of the cleaning
sequence, allowing for short cleaning time.
Example - 2 nozzle machine:
TD523451
TD523452 TD523453
0.8 min. 2.3 min. 6 min.
The time needed to perform a proper cleaning depends on type of soilage, distance, cleaning procedure and agent. For sub-
stances that are easily mobilised, i.e. are easy to remove, less than 1 min. could be sufficient while in cases of more heavy soilage
(high viscous, sticky substances, etc.) a more dense pattern/longer time will be needed.

Toftejorg SaniJet 20 Air driven
Machine with external motor drive
The machine is driven by a gear motor mounted on top of the Inlet housing. Via a Magnetic clutch the rotation of the gear motor
is transmitted from the outside through a closed wall to the Output shaft placed inside the Inlet housing. The Output shaft is in
mesh with the Down pipe and rotates the Down pipe in the same way as in the media driven version.

The output shaft of the gear motor is equipped with a Rotor with permanent magnets. The rotor is placed inside the cavity in the
Motor flange, made by the cup protruding into the liquid chamber in the Inlet housing. The cup is welded to the motor flange as
a hermetic sealed closed wall between the liquid chamber and the outside. The magnetic field from the permanent magnets is
transferred through the wall, to a ring with permanent magnets inside the Output shaft, which is placed around the cup on the
inside the liquid chamber.

Toftejorg SaniJet 20 Air driven
Self-cleaning
Apart from the main flow flushing the inside of the Base housing and the Down pipe, and thereafter forming the jets through the
Nozzles, fluid is flushed through all internal cavities, through Bevel gear, Ball bearings and gabs between moving parts and is
finally also used for cleaning of the outside surfaces of the machine. From the gab between the Base housing and the rotating
Down pipe, a cleaning jet is directed against the Down pipe, thus loosening and removing product remains on the outside. A
liquid film flushing all around the tube further assists by continuously transporting away loosened product remains. The front of
the Cleaner head is flushed by a liquid flow from the gab between the Cleaner head and the Retaining ring.
In order to ensure a proper self-cleaning, the machine must be installed in an approx. upright position and the inlet pressure
must be min. 3 bar. In the bottom of the Cleaner head, in the Retaining ring, the machine is equipped with a hole to ensure
self-draining. This self-draining is only ensured, if the machine is installed in an upright position.
Cleaning Pattern, The Golden Section
The patented Golden Section cleaning pattern (EP-Patent No.: 0495883. US-Patent No.: 5,279.675) is unique in building up
the pattern in an ultimate uniform way. The pattern starts very coarse and refines itself in a step-less way by laying out the
tracks approximately in the middle between the two most distant tracks already made. This means that the jets always clean
the areas containing most remaining product, and thereby remove as much deposit as possible in the shortest possible way.
In case a complete cleaning pattern is not required, it will be possible to reach the same cleaning level within half the time and
by using half the amount of cleaning fluid compared to a traditional step-wise cleaning pattern. Furthermore, due to the uniform
cleaning pattern, the cleaning can be stopped at any time, whereas with traditional non-uniform cleaning pattern this would not
be advantageous. However, after the complete cleaning pattern has been established, the difference between the Golden
Section and the traditional stepwise cleaning pattern is negligible.

4.3 Installation of Air Motor
Important information
Recommended inlet air pressure is not to exceed 6 bar (87) psi maximum. It is recommended to use an air filter and moisture
trap on inlet air supply to avoid contamination being fed into air motor.
General information
The air motor is designed to be driven by compressed air and under no circumstances be driven with any other gases.
Fluids, particles, solids or any substances mixed with air, particularly combustible substances likely to cause explosions,
must not drive air motor.
Warning: Do not drive with flammable or explosive gases.
Warning: Air motor is designed for air only. Do not allow corrosive gases or particulate material to enter motor. Water vapor,
oil-based contaminants, or other liquids must be filtered out.
Warning: Do not use a hammer or force coupling or drive pulley onto shaft when installing drive onto air motor. This causes
end thrust that could damage air motor.
Note: Ambient temperature outside tank should not exceed +40°C (140°F)
Installation
Install a moisture trap and filter in air line ahead of motor. For efficiency of output and control of speed, use air lines of
same size or in next pipe size larger than intake port of motor. As inlet line a ø8/5.5 tube should be used (customer supply).
As standard, the drive unit is fitted with a hose connector ø8 on the blow-out line. It is possible to lead the exhaust out of the
room with a hose and it is recommended in this context to use an adapter so that a ø12 tube or larger can be used for this. It
is also possible to attach a silencer on the exhaust, but in this respect it should be borne in mind that a possible oil mist may
contaminated surroundings in the room where it exhausted

Toftejorg SaniJet 20 Air driven
Lubrication
The pneumatic oil used for lubrication must have a self–ignition temperature above 260°C and have a viscosity between 22 and
46 cst depending on the temperature of the motor operation (e.g. 40°C the viscosity of the oil shall be between 22 and 30 cst).
MODEC recommends that an automatic air line lubricator, be installed in air line just ahead of air motor. Lubricator should be
adjusted to feed with 50mm³ of oil per m³ of air (1 drop = 15 mm³) (see table below).
At max power At max speed
Air cons. (1/min) Lubrication (drops/min) Air cons. (1/min) Lubrication (drops/min)
290 1360 1
Valve mini Kv Max air flow (1/min) Feeding pipe min. dia. (mm) Connection min. dia. (mm)
20 1293 6 5
Lubrication is necessary for all internal moving parts. Excessive moisture in air line can cause rust formation in motor and
might also cause ice to form in muffler due to expansion of air through motor. Moisture problem can be corrected by installing
a moisture separator in line and also by installing an after-cooler between compressor and air receiver.
A lubricant filter (FRL) unit should be installed between upstream from the motor. Filtration should be 50 micron maximum.
Mounting
Warning: Beware of any exposed and/or moveable parts. Proper guards should be in place to prevent personal
and/or property damage.

4.4 General safety and installation instructions
The Alfa Laval Toftejorg SaniJet 20 is designed to be installed in a vertical upright position.
It is recommended to install a filter with mesh size 250 µm (0,0001") in the supply line in order to avoid particles, scale etc.
from clogging inside the machine. It is essential to avoid fine solid particles, such as fine sand, in the cleaning fluid as they will
increase wear considerably. This is particular important in case of recirculation.
In order to prevent accidental leakage of cleaning fluid into the tank it is recommended to install a shut-off valve close to
the machine inlet. This will also prevent back-flow of liquid from the tank through the machine in case the cleaner head is
submerged and there is an over-pressure inside the tank. The installation and operation shall be made in such a way that the
draining of the machine is ensured.
It is recommended that the fluid valve fitted is of a type that prevents hydraulic shocks, which may cause severe damage to
the entire installation.
Before installation, all supply lines and valves must be thoroughly flushed to remove remains of welding electrodes,
grinding dust, scale and other foreign matter.
During handling and installation handle the machine with care in order not to damage the fine surface finish of the machine.
The Alfa Laval Toftejorg SaniJet 20 machine has been tested in a test tank, according to Alfa Laval test procedures at the
factory before shipping.
NOTE
Note: Do not try to turn Nozzle head by hand, since this may damage the Gear. Nozzle head can be turned by blowing air from
an air pistol through the inlet connection of the media driven machine or the intake port of the air motor.
NOTE
The machine shall be installed in accordance with national regulations for safety and other relevant regulations and standards. In
EU-countries the complete system must fulfil the EU-machine Directive and depending of application, the EU-Pressure Equipment
Directive, the EU-ATEX/IECEx Directive and other relevant Directives and shall be CE-marked before it is set into operation.
Warning: Precautions shall be made to prevent starting of the cleaning operation, while personnel are inside the
tank or otherwise can be hit by jets from the nozzles.
