Dry Extruder

General Description
It can be used for the expansion of rice bran, soybean, maize, rice powder and feed, kinds of grain extruding ,etc. It's appliable for the production of oil factory, rice factory, soybean protein factory, feed factory, etc.

The machine is of big production capacity, low power consumption. After extruding, ricebran can keep fresh for two months, the extraction yield can be 30-45% higher, residual oil in extracted dry meal less than 1%, the protein content, color both better than granulating-drying-extracting process. After extruding, soybean can be deodorized, urea enzyme in soybean can be passivated, the extraction yield can be 45-50% up, the residual oil content in meal less than 0.8%, the protein content and color both better than drying-extracting process.

Extruding Principle
By squeezing, rubbing, shearing forces of pressing worms of unequal thread pitches in the extruding cage, the mechanial energy is converted into heat energy, forms certain pressure and temperature in the extruding cavity, from the outlet die head, the extruded material spray out and inflated .

Wet Extruder 

 General Description

The machine is applicable for the extruding of low oil content crops such as rice bran and soybean or pressed cake before solvent extraction, is an ideal production process for the purpose of reducing equipment investment, raising production, reducing energy consumption and improving product quality of oil plants worldwide.

The oil material is squeezed, heated, sheared and rubbed in the extruding cavity of the machine, and mixed, 

steamed, 

gelatinized by injected direct steam, the pressure in extruding cavity will reach 1.4-4.0 MPa, the temperature reachs 110-120℃, at the die head outlet suddenly reduce to normal pressure and 

temperature, the steam vaporizes abruptly, oil in seed cell run outside then, and extruded material with 

numberless minus holes and cracks got.And because of such extruding effects, the permeating of solvent through cells and permeating of oil out from cells both become easier, so the extraction and desolventizing 

process both get more efficient, the unit weight of material is raised about 30% , so the production capacity of extractor is also raised. The stay period of 

material in the extruding machine is less than 30 seconds, so the damage of the content of material is little, which 

helps the protection of the quality of material.
