General Description of rice bran extruder puffing machine :
The rice bran extruder puffing machine is applicable for the extruding of low oil content crops such as rice bran and soybean or pressed cake before solvent extraction,rice bran extruder puffing machine 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. There are many kinds of puffing machine, can be divided into soybean oil puffing machine, rice bran oil puffing machine, high oil pre-press oil puffing machine, and tissue proteins oil puffing machine and so on. According to different treatment for different oil seeds. In addition to puffing process, different kinds of oil seeds may also need cooking, softening, flaking , drying and other processes to get the most oil yield and meal of better quality.

Adopting the rice bran extruder puffing machine can both improve the yield of rice bran oil and reduce the consumption. The extrusion puffing, on the one hand, can make solution lipase in the rice bran passivated under high temperature and high pressure condition, then prevent the rice bran oil rancidity; On the other hand, the extrusion puffing can make rice bran be porous material grain, and increases the materials bulk density, then improve the permeability and leaching rate which solvent reacts to the material.

Working principle of  rice bran extruder puffing machine:

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 110-120º C, 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.

Mian features of rice bran extruder puffing machine:
1.   Improving production capacity of extractor
Bulk density of extruded materials increases 20%--30% than this of raw cake, so process capacity of extractor and desolventizer-toaster is improved.

2.   Improving extraction speed, reducing extraction time
Cell structures of extruded materials are destroyed completely, microhole number of extruded materials is increased, so penetrability which solvent and mixed oil pass through materials layers is improved.

3.  Solvent content of wet meal is lowered, reducing load of wet meal desolventization.
Because of good penetrability and drying, solvent content of wet meal can be lowered to 20% or so. Loads of wet meal desolventization and solvent recovery are reduced, so steam consumption of wet meal desolventization is saved.

4.  Improving mixed oil concentration, lowering load of mixed oil steaming
Mixed oil concentration is improved from 20% or so to 28—30%, saving steam consumption of mixed oil steaming process.

5.  Enzymes of oil materials are passivated, improving extracted crude oil quality
Enzymes and anti-nutritional factors of oil materials are passivated, which avoids lipoxygenase and phospholipid enzyme effect on phospholipid of oil materials, reduces non-hydrated phospholipid content of extraction crude oil, and increases total phospholipid content of extraction crude oil. So oil refining efficiency is improved, oil product quality is also improved, as well phospholipid by-products output and phospholipid product quality are increased in hydrated degumming section.

6.  Improving output of germ pressing equipment
In expanding extraction section, it isn’t strict for thickness of raw germ, thickness of rolling germ may lower requires adequately, so output increases.

7.  Lowering power consumption in extraction process section
Mixed oil concentration is improved,and solvent content of wet meal is lowered, which reduces efficiently solvent consumption. Improvement of production capacity makes production cose lower.

8.  Simple operation
