The control of the cooling process makes it possible to produce consistently high quality products.
For example, in the production of food products (sauce, mayonnaise, adjika, etc.), cooling equipment - heat exchanger is used. Refrigeration equipment is designed to cool just cooked finished product, then the product is packaged in containers.
The heat exchanger cools the product by circulating glycol through the heat exchanger jackets.
The volume of glycol supplied to the heat exchanger is dosed by a control valve. The glycol circulation speed is set by a centrifugal pump with frequency converter.
In this case, products need to be produced in a strictly limited time, which requires fine-tuning of the heat exchange process, which can be helped by monitoring this process to collect parameters during real production, which will give the opportunity to "polish" the control programs of the heat exchange process.
