Overview
Machine Overview:
The Hinds-Bock SP-64 liquid depositor is designed to deposit liquid products such as sauces and batters. The
Hinds-Bock machines are built with both the operator and the maintenance staff in mind. They are simple yet
rugged, easy to operate, and to dismantle for either sanitation or routine maintenance. While it can handle a
wide range product viscosities, this machine is not designed to work with products that have viscosities below
that of water, which are abrasive, have large particulates, or any dry products.
Component Explanation:
*Please note that our machines are custom made based on customer’s purchases and requests. Some of the
following items may not be on every machine, but this manual covers most available options.
1. Hopper: Holds product supply for the depositing process.
2. Main air cylinder: Used to push (deposit) and pull (suction) the product piston in and out of the product
cylinder during operation.
3. Product spout:(type varies with application and product) Directs product from the product valve and
dispenses with a clean cutoff.
4. Product valve: Redirects product from the hopper to spout using a suction/deposit rotation cycle.
5. Cylinder Foot: Holds the product piston in line with the main air cylinder and the product cylinder.
6. Stroke Adjust: Increases and decreases the deposit amount by moving the product piston.
7. Piston and Cylinder set: The piston and cylinder are used in conjunction to pull the product from the
hopper and push it to the product valve. These are interchangeable based on the deposit size needed.
8. Foot Switch: Used to initiate the deposit.
9. Agitator:(not shown) Agitates the product to keep the consistency and temperature even.

Label Identification and E-Stops
Air Dump Valve:
To remove pneumatic energy from the system, use the air dump valve. This will
exhaust all of the air from the system. This also acts as an E-stop. When the dial is
turned to show “EXH” in the window, then the air is dumped.
When performing maintenance tasks, the power
disconnect switch must be locked using the in plant lock
out tag out (LOTO) procedures.
Pinch point/Crush hazard:
DO NOT operate without guards in place and shut off air and electrical power
before servicing.
Burn hazard:
Avoid touching surfaces/ components during operation. Wait an appropriate
amount of time for cool down before servicing.
No Step:
This designates parts or surfaces of the machine that are not designed to
support the weight of a person.Using these areas as a step could result in
injury and/or damage to the machine.
Pg. 6

Setup
Receipt of Shipment:
Immediately upon arrival, the Hinds-Bock machine should be uncrated and inspected for any damage that may
have occurred during shipment. Check to see that all items listed on the packing sheet are included. If
damages or shortages are noted, the transportation company and the Hinds-Bock Corporation should be
notified immediately.
Applying Brakes:
After rolling the machine into position, apply brake levers on each of the casters
before connecting air.
Adjusting Machine Height:
Once the machine has been locked in position, the height may be adjusted. Do so by
loosening the star knob on the stand, and then turn the hand crank located on the
side of the machine. Once the desired height is achieved, make sure to tighten the
star knob to avoid accidental height changes.
Pre-Start Checkout:
Before applying air to the machine, or filling it with product, it should be disassembled, and all food contact
parts should be thoroughly sanitized and lubricated. See the Maintenance and Cleaning section of this manual
for instructions on cleaning.
When disassembling or reassembling components of the machine, never use force other than hand
pressure. It is not necessary to use hammers or mallets during any of the operational procedures on this
machine.
The air cylinders and connecting hoses must never be allowed to submerge in water or solvent during
the sanitation process, and should be kept out of direct high-pressure spray when the hopper is being
washed. If water or solvent is allowed inside the small plastic air lines connected to the cylinder,
premature damage and failure of the air cylinder will result. Unless a quick release is present, there
should be no need to detach the air hoses from their respective assembly.
Whenever parts are removed from the machine for cleaning, maintenance, etc., they should be stored
in an area safe from damage.
If this machine is equipped with an electronic signal device, this unit along with the sensing head must
be removed and placed in a dry area while the machine is being washed and sanitized.
During the sanitation and re-lubricating process all parts, especially O-ring seals and gaskets, should be
inspected for nicks, cuts, cracks or other imperfections that might cause improper operation. Worn or cut O-
rings or seals should be replaced. Once the machine has been placed into operation, the product should serve
as a satisfactory lubricant.
As with any fine piece of equipment, the machine should be thoroughly cleaned and re-lubricated with
appropriate jelly lubricant at the end of each run. Lubrication should be accomplished with a good grade of
food approved jelly lubricant compatible with the product. It will then either be ready for another series of
production operations or be well lubricated to prevent the seals from drying out should it be out of operation
for a short period. Whenever maintenance, parts or service information are required and correspondence
Pg. 7

with the factory is necessary, always include the model number and serial number. This will help to avoid
errors and/or shipping delays. Parts must also be requested by part number.
Air Connection:
Under no circumstances should the air supply pressure exceed 125 psi.
Air services should be brought to the machine. Compressed air should be as clean and dry as possible. A filter
and regulator have been provided as integral parts of this machine for the purpose of properly powering the
machine during operation. To assure an adequate air supply to the machine, it is suggested that the airline
leading to the machine be at least one-half inch inside diameter minimum. When connecting the air supply,
ensure the air dump button is depressed.
Once the air and power are connected, the air pressure gauge will not register until the machine has been
RESET.
SIR Box (Where applicable):
The SIR (Single Impulse Relay) box is used to communicate between an
electrically driven machine, and a pneumatic machine.
The two air hoses on the top of the box should be attached to the quick
connects on the Hinds-Bock depositor air assembly in place of the foot pedal
hoses.
Either a connection from another machine, or a photo eye mounted on a
conveyor should be connected to the bottom of the SIR box. This will provide
the electric “Go” signal that will be converted to the pneumatic “Go” signal that
the depositor will use to initiate the deposit.
Blow Off Box (Where applicable):
The blow off box is used to adjust the length (in time) of the blow off once the
deposit is complete. The yellow hose carries the air signal from the depositor
when the deposit is complete. The clear hose gives the blow off box a constant
air supply from the air prep assembly. The blue hose connects to the spout and
is the air supply for the blow off which is metered by the box.
Pg. 8

When the machine is done with the deposit, the blow off box is signaled to
initiate the blow off. The round dial in the middle area of the box controls how
long the blow off will last. To reduce the amount of time, turn the knob
clockwise, and the opposite direction to increase the time.
Production Start-Up
Starting the Machine/E-Stops:
Confirm that the emergency stop button is disengaged and that all safety covers are in place. The air
valve is off when the red air dump knob shows “EXH”. Turn the knob to the open position (it will display
“SUP”). If some pressure other than 90 PSI is indicated, adjust it by pulling the lock sleeve away from the dial,
located on the regulator, and turn it until 90 PSI is indicated on the gauge. Push the sleeve back into its
original position to lock.
Fill the hopper with product, place an empty container beneath the spout, and cycle the machine using
the foot pedal (or signals from another machine’s inputs) until product is dispensed consistently. To set the fill
volume or amount required per cycle, hold an empty container under the nozzle and cycle the machine.
Weigh the output of the product. To adjust the deposit weight, follow the instructions under the “Stroke
Adjust” portion in the following section. When the proper weight is achieved, record the settings of the
machine for recipe creation with future production runs.
Stroke Adjust:
Adjust the weight of each deposit by bringing the stroke adjust forward or by
moving it backward. Do this by loosening the knob on the top of the assembly,
then rotating the hand wheel to move the stroke adjust. Small adjustments can
be made while the machine is depositing; but for larger adjustments, dump the
system air before making the adjustment. Once the proper weights are obtained,
tighten the knob to prevent the hand wheel from moving unintentionally.
Flow Controls:
Use the flow control (found on or near the main air cylinder) to adjust
the air flow out of the air cylinder, changing the speed of the deposit.
The orange air hose supplies air to push the piston towards the hopper
(initiating the deposit), and the yellow air hose moves the pistons back
away from the hopper. The controls adjust the pressure at which the air
flows out of the cylinder; lowering the pressure on the side closest to the
hopper will increase the speed at which the machine deposits.
For thick products, or those that have a tendency to foam, the speed
should be slowed to reduce the amount of air that will be pulled in with
the product as the pistons retract.

Controlling the Machine:
On the most basic level, the machine is controlled by either of two methods: Manual or Automatic.
Manual cycling can be accomplished in the following ways:
Hand operation, either air or electric, is accomplished by activating a switch by hand.
Foot operation, either air or electric, is accomplished by depressing a foot switch.
Semi-automatic operation can be accomplished by holding either a hand or foot switch in the depressed
position, thereby causing the machine to continue to cycle at a preset speed.
Automatic cycling can be accomplished in these ways:
No contact actuation: In this situation the container to be filled passes a photoelectric, electronic or
pneumatic sensor which will send signals back to a switch causing the filler to cycle.
Signal actuation: The machine receives a signal from other equipment telling the filler to cycle.
If the machine signaling device is to be attached to the conveyor or some other piece of equipment, care
should be taken to locate the device in such a manner that it will cause the machine to cycle when the
container to be filled is in the appropriate position.
Maintenance and Cleaning
While Hinds-Bock supplies a system and basic guidelines, it is the customer’s responsibility to validate the
cleanliness of the machine and its parts.
When cleaning the machine or performing maintenance, all O-rings should be inspected and replaced if
any damage or wear is noted. Lubricate all O-rings with a good grade of food approved jelly lubricant
compatible with the product before re-assembling the machine.
Ideally, the cleaning processes should be performed in the order shown below.
When cleaning the machine or performing maintenance tasks, the power
disconnect switch and the air dump valve must be locked using in plant lock out
tag out (LOTO) procedures.
1. If the machine has Delrin parts: Do not use hot water when cleaning; itcan
cause thewhite Delrin parts to swell making disassembly difficult.
2. Do not use CHLORINATED cleaning or sanitizing chemicals on the depositor;
they can cause damage to the machine.
3. The air cylinders and connecting hoses should be kept out of direct high-
pressure spray when the hopper isbeing washed and should never be submerged
in water.
Air Supply:
The air pressure regulator is used to maintain a constant pressure in the
system. Avoid pressure drops greater than 10psi. If the pressure does drop
more than 10psi, the CFM being supplied to the depositor may be too low.
Maintain a consistent air pressure in the system (85-90psi) to achieve the
best results.
To make adjustments to the air pressure, pull the knob on the pressure
gauge away from the dial. Rotate the knob until the dial reads
approximately 90psi. Push the knob back in to lock into place once more.
Pg. 10

Air Filter:
The air filter protects the pneumatic system from excess particulates and
condensation. The filter bowl is equipped with a normally closed auto drain
feature. When condensation builds up in the filter bowl the float lifts,
activating the drain. The air filter bowl on air assembly should be drained
daily. It is normal for this bowl to collect water during the use of the
machine and this water should never be allowed to stand in the bowl.
There is a small drain valve in the bottom of the plastic bowl. Never use
pliers to tighten this valve. Finger tight is all it will ever need.
Air Supply Lubricator:
The air supply lubricator should be checked daily. This ensures that the air
motor agitator stays well lubricated, which is necessary to avoid damage.
Cleaning the Hopper:
1. Run any remaining product out of hopper.
2. Turn the air dump valve knob to dump the air from the machine.
3. Put approximately 2 gallons of LUKEWARM water into the hopper with about a
teaspoon of Dawn® or equivalent grease dissolving liquid dish washing
detergent. Gently scrub off any remaining product with a soft brush.
4. Reset the machine.
5. Run the cleaning solution through the machine, and then continue with clean
water until no residue remains.
6. Remove the hopper from the product head by taking off the tri-clamp at its
base.
Cleaning the Agitator
(if present):
1. Follow the instructions for cleaning the hopper prior to cleaning or
removing the agitator.
2. E-Stop the machine and remove the air supply.
3. Remove the hopper lid.
4. Loosen the knob on the back side of the agitator mount and gently lift
out the agitator.
5. Keep the air hoses and upper portion of the agitator away from the
water as much as possible.
6. Clean the agitator shaft in a COP or similar washing basin.
Removing the Product Valve:
7. Remove the quick pin connecting the product valve H-arm and cylinder.
8. Lift the lock bar away from the product valve.
9. Pull the product valve out while rotating back and forth to prevent the
O-rings from getting caught on the product head ports.

Pg. 11

Removing the Product Piston:
1. Move the stroke adjust to its most retracted position (as shown).
2. Depending on the type of piston, it may need to be removed in one of
the following ways:
a. Unscrew pistons from the air cylinder foot.
b. Slide the piston head off of the piston rod through the cutout located
on the base of the piston head (shown here).
Removing the Product Cylinder:
1. Follow the procedure for removing the product piston prior to removing
the product cylinder.
2. Depending on the type of cylinder, it may need to be removed in one of
the following ways:
a. Grip the product cylinder and turn counter clockwise to remove.
b. Use a spanner wrench to loosen the product cylinders from the
product head.
Cleaning the Product Head:
1. Remove the product valve and cylinder prior to cleaning the product
head.
2. Use a soft round brush to gently scrub out the ports using a mixture of
approximately 2 gallons of LUKEWARM water with about a teaspoon of
Dawn® or equivalent grease dissolving liquid dish washing detergent.
3. Rinse with clean water until no residue remains.
Removing the Product Spout:
Depending on the product being dispensed, the product spout can come in
many different styles. All should be detached and cleaned in approximately
the same way (as described below). If further instructions are needed for
your particular spout, please contact the Hinds-Bock corporation for further
diagrams and details.
1. Begin by detaching the clamps shown.
2. Be sure to keep the air hoses and cylinder out of the water when
cleaning the spout. Water in the air hoses can cause damage to the
machine.
