CALLIFREEZE is a new freezer control system that is exclusive to GEA spiral freezers. The new system can be configured for S-Tec and A-Tec freezers handling a wide range of food products including meat, poultry and fish, ready meals, bakery and dairy products. CALLIFREEZE monitors the condition of products exiting the freezer, and then automatically calibrates the freezer parameters to ensure that every product is frozen according to optimum requirements.
CALLIFREEZE monitors the condition of products exiting the freezer, and then automatically calibrates the freezer parameters to ensure that every product is frozen according to optimum requirements. The control system achieves this by continuously monitoring the level of crystallized water in the food products, and automatically adjusting product retention time in the freezer, air temperature and fan speed to achieve the precise level of freezing required, with minimum energy consumption.
Continuing to cool a product once it has already reached the required degree of freezing is not only unnecessary, but it is also a waste of energy. Some products need to be 100% frozen, while for other applications an 80% level of frozenness at freezer discharge is acceptable, with product ‘finish off’ occurring in the cold store, to maximize energy savings. However, until now there has been no way of checking the level of frozenness of products as a continuous part of the cooling process. CALLIFREEZE uses GEA’s unique sensing technology to measure the level of frozenness inline, at the freezer exit, without direct contact with the food product. The system then automatically adjusts the freezer parameters to maintain perfect freezing conditions according to customer and product requirements.
