Spiral Tubular Pre-heater
It preheats crushed fruits to prevent from brown effect and increase the rate of concentrated juice.
Stainless steel AISI 304 supports structure for;
1) Spiral tubular : It consists of double layer pipe; products flows inside inner pipe and hot water flows inside outer pipe. Therefore heat exchange is accomplished between hot water and products.
2) Hot water generation : It consists of hot water pump, inline heater and expansion tank. It generate hot water by mixing normal temperature water with steam and sends to tubular.
B) Description of operation
The length of spiral becomes different according to the property of products. Steam control valve is controlled by the thermal sensor depending on the setting up temperature.
