Edible oil machine Adjusting range of the parameter in process of fine equipment decolour

Edible oil machine

Adjusting range of the parameter in process of fine equipment decolour is as follows:

1. temperature. Grease adsorption is put in physical change already in decolour process, put in chemical change again, and be accompanied follow an energy change. The temperature that normally physisorption place requires should be controlled in 40~80 ℃ , chemical adsorption should be controlled in 80~110 ℃ .

2. handles pressure. According to us old production carries out experience, below decompression environment, pressure is when 6.6~9.3KPa, can control what water divides to evaporate speed, improve decolour result.

3. agitate. In process of fine equipment decolour, the opposite density of sorbent is big, easy sink, ceaseless agitate can make sorbent distributings equably in grease. Often press decolour commonly, stirring strength achieves sorbent to assume position of even in suspension can; Decompression decolour can increase a little, but do not cause grease to splatter.

4. decolour time is controlled. The decolour of edible grease undertakes below appropriate temperature, stirring strength and negative pressure condition, sorbent is in to the adsorption of pigment 15~20 minute namely saturated. When intermittent type decolour, because filter,the cooling need before keeps period of time, accordingly decolour time should be lengthened in 20~30 minute, in order to achieve favorable decolour result.
