Two systems are used to transfer the mixture from the stainless steel hoppers kept at a controlled temperature to the freezing cylinders: gravity (GR) or via a gear pump (PM). The gravity system is simple and reliable, and guarantees a good overrun (increase in volume). The pressurising gear pump system, on the other hand, increases output capacity and lets one increase the overrun even more.

The Bag-in-Box (BiB) and heat treatment (HT) systems are Gel Matic’s answer for those who want maximum hygiene. The practical BiB container holding the liquid mixture sits in a refrigerating cabinet and eliminates virtually all contact with the air.

The machines based on HT technology offer the opportunity to heat treat the mixture thanks to a special refrigeration system monitored and run via (Interactive control & Diagnosis System).
