The seasonality of fruit and vegetables is a problem in all the food processing plants. Raw material is usually frozen for storage purposes. The first production stage is fruit defrosting.
B&P Engineering offers a new device – Termobreak – used for defrosting, steam-pressure heating and heating of pre-fragmented raw material in a liquid or semi-liquid form.
The standard open heating appliance consists of an U-type heating chamber placed on a carrying frame. The feed hopper is mounted in the upper part of the heat space. At the end of the heating chamber there is a closing lid that can be lifted by the manual hydraulic system. There are two rotating spirals inside, mounted on the common shaft. In places where the shaft goes out of the wall, the sealing glands have been installed. The heating spiral shaft has been arranged with two standing bearing units on both sides with increased technical resistance. The heating spiral is driven by a chain drive with a gear-motor.
The whole heating chamber is insulated. Type and thickness of the applied insulating material is adjusted to the operating temperature the appliance has been designed for. Inside the heating chamber there is CIP-washing system installed.
The biggest advantage of this appliance is the rotatable heating unit in shape of two spirals placed on the common shaft. Heat exchange efficiency is 5 times greater than the tube heat exchangers. The product is heated equally throughout the entire volume and continuously stirred.
