Introduction of wet extruder working principle
Low temperature press - Wet extruder STXP162 How it works:
Applicable to rice bran, soybeans and other low-oil oil and pre-pancake in the solvent before the puffing treatment, is an ideal production process. Has become a domestic and foreign oil plant to save equipment investment, increase production, reduce energy consumption, improve product quality an important means.
The oil is squeezed, heated, sheared, rubbed and so on in the extrusion chamber of the extruder, and the direct steam is injected so that the material is fully mixed, cooked, gelled and gelatinized. 1.4 - 4.0MPa, the temperature of 110 - 120 degrees Celsius, in the expansion machine at the exit of the template suddenly reduced to normal temperature and pressure, rapid evaporation of water vapor, intracellular oil full exposure, resulting in numerous tiny pores and surface cracks in the expansion of materials.
It is easier to leach the oil into the oil cells and oil from the cells due to the puffing effect, which improves the leaching and desolvation efficiency. Also increased the material bulk density of about 30%, thus improving the processing capacity of leaching equipment. As the material in the expansion machine to stay a short time (less than 30 seconds), less effective components damage to the quality of raw materials to protect the benefit.
