Continuous control system added to spiral freezer

08 April 2019

GEA has added its Callifreeze control technology to the S-Tec range of spiral freezers. The S-Tec range was first introduced in 2016 for poultry, meat, fish, ready meals, bakery and dairy applications that require capacities of up to 6,000 kg/hr.

The Callifreeze solution takes its name from its ability to calibrate the freezer, having controlled the level of frozenness of the products. This is said to reduce power consumption, improve efficiency and ensures consistency of product quality. It is able to calibrate the freezer parameters through the continuous measurement of the level of frozenness of the product at the freezer exit. It does this by monitoring the level of crystalized water in the products and adjust the retention time, air temperature and fan speed to achieve the precise level of freezing required, with the minimum of energy consumption.

The S-Tec freezer uses a fully-welded construction for the whole of the product-contact belt area to eliminate dirt traps. It is also available with a fully-welded modular floor that does not require floor heating. Again, this removes dirt traps with structure elevated on pins welded to the floor for easy cleaning.
