Batch Chiller Systems
Filtrine has been providing ingredient water chillers, jacketed mixer chillers and combination coolers for mixers since the 1940's for the food industry. Filtine's unique storage-type design provides consistent 34°F [1.1°C] water without fear of freeze-up for ingredient mixing. Filtrine's chillers can cool food-graded glycol to as low as 10°F [-12°C] for jacketed mixers to control heat generated during the mixing process.
Filtrine batch-draw chillers can also be used for general food and pharmaceutical processing applications. In addition, contact us about our continuous, stainless steel, coil-in-bath heat exchanger, which is steam cleanable and ideal for cooling viscous foods.
Or you can get the best of both with a Filtrine combination ingredient and jacket cooler. This option could save you space and money. Contact a Filtrine Representative to discuss building the right combination for your food processing or other needs.
Batch Draw Ingredient Chillers
Because of their unique design principle and superior construction Filtrine chillers
have become standard throughout the industry for dependable uniformity in ingredient
batch-draw water cooling. Unlike instantaneous chillers which are in constant
danger of freeze-up at temperatures below 45°F [7°C], Filtrine chillers are specially
designed with high-transfer immersion coil evaporator and large holdover storage to
supply ingredient water at 34°F [1°C] and to maintain temperature setting within ±
This important storage feature not only provides a large volume of chilled water for
dough; it also acts as a refrigeration “cushion,” preventing overload and “short cycling”
common to chillers without storage.
Batch Draw Operation
Flow-activated solenoid valves permit the tank to be filled and internally agitated
to prevent freezing at low temperatures. When metering valve at the mixer calls
for chilled water, up to 75% of the storage capacity is pumped out at the rate of
10-50 gpm. Solenoid valves automatically shut off the intake to prevent a mixture
of incoming water with the batch so that water temperature is uniform from
the first gallon to the last.
When the required amount is drawn, the flow switch reverses the solenoids to
refill the storage tank and return the pump to internal agitation until the next
batch is required.
