On the product infeed side, a water buffer with pump is mounted. On the product outfeed side, sprayers are mounted which add cold water. The product and water flows both go through the cooler in opposite directions.
The hydro cooler type HC-7800 is suitable for cooling baby carrots, potatoes and the like. The maximum processable diameter is 25 mm and the maximum dwell time is 15 minutes.
The capacity of the hydro-cooler largely depends on the product diameter, input core temperature, and desired output core temperature. Experience has shown that the capacity is between 500 and 1,500 kg per hour.
