Technology of cooking oil extrusion machine:
Puffed extruder molding technology using mainly powdered or through flaking of sheet materials, certain functional heat treatment, namely through mixing, extrusion, gluing, vacuum puffing forming, cutting and cooling, drying and other physical and biochemical processes , so that the material to form mature embryos have some structured shapes, which will help the oil.
Oil extrusion machine
Oil extrusion machine works:
After flaking flake or powder form of fuel, input through feed auger extruder, after being in the propeller by direct steam is injected into the hot and humid temperature adjusted, subjected to the action of the spiral and the shear pin bore in the machine, the produced a strong friction, chopped, kneading, extruding, temperature, humidity, pressure rising, so that sufficient fuel cell destruction, moderate protein denaturation, harmful substances are passivated, oil viscosity decrease. High temperature, high pressure material was eventually pushed out of the discharge end, the die orifice jet burst out instantly buck. Making materials dramatically expanded, rapid evaporation of the moisture content to form a porous structure. Become high strength, permeability, cooked in favor of germ oil extraction.

Oil extrusion machine technology application:
Because of the unique features puffing technology, therefore, in theory-oil technology research, production and application of practice flourished puffed pretreatment technology, the reform of the world oil production generates huge boost today soybean flaking, expanded molding - direct leaching; pre-pressed canola rapeseed puffing - such as oil extraction process has become a mainstream technology, so people are very concerned about it.
Improve the oil extraction efficiency of oil extrusion machine, reduce the oil residue in the meal:
(1) the blank extrusion, cell destruction thoroughly, the grease evenly diffusion aggregation, conducive to oil;
(2) the formation of solid and porous "mature embryo", permeability is increased when the solvent leaching, and the leaching after meal mixed oil drain, greatly improving the oil rate.
Leaching or press machine processing capacity is greatly improved:
(1) to relax the conditions of pretreatment, such as rolling embryo does not have to be too thin, greatly improving the pretreatment equipment and flaking machine processing ability;
(2) expanded "mature embryo" bulk density than embryos have greatly improved especially for powder material such as rice bran, corn germ embryos, so that the extractor year-on-year increase in throughput by.
Significant in energy saving of this kind oil extrusion machine:
As the leaching solvent ratio decreased, mixed oil concentration increased, prompting the mixed oil evaporation, vapor mentioned steam, cooling water consumption greatly reduced condensation system. According to estimates can reduce the consumption of 20%-30% steam.
Improve the nutritional value of crude oil and meal protein
Expanded to stock the instantaneous high temperature hydrothermal pretreatment, in effectively maintain the nutritional value of protein at the same time, but also can selectively reduce or eliminate oil in a variety of adverse effects of anti nutritional factors, is conducive to improve the quality of the product; than the steaming and stir frying heating time much shorter crude oil, light color, low acidity, non reducing hydration phosphatide content.
Expand the scale of production, reduce production costs
The practice proves that by the traditional process into puffed - leaching process, the same production line capacity increased by more than 40%, such as 1200t/d (soybean) increased by 2000t/d. The steam consumption is reduced 20%-30%, solvent consumption decreased 0.1%, 0.15% decline in residual oil, refining yield increased by 0.1%, tons of material consumption decreased by 1KW.h. Thus, for large and medium-sized oil refineries to improve economic benefit is very considerable.
