rice bran expander extruder machine

Rice bran extruder general description:

The rice bran expander is used to extrude low oil crops such as rice bran and soybeans, or pressed cake before solvent extraction. Rice bran expander is an ideal production process with the goal of reducing investment in equipment, increasing production, lowering energy consumption and improving the quality of oilseed products around the world. There are many types of blowing machine, which can be divided into soybean oil pressing machine, rice bran oil pressing machine, high-pressure oil pressing machine for pre-pressing, tissue protein oil pressing machine and so on. Different processing of different oilseeds. In addition to the inflation process, various types of oilseeds may also need to be boiled, softened, peeled, dried and other processes in order to obtain the maximum yield of oil and flour of the best quality.

Why puff before solvent extraction?

1. Increase the power of the oil separator. After extrusion, the bulk mass increases by 20-30%, which significantly increases the performance of the extractor.

2. Increases the efficiency of the extraction plant, reduces the time of extraction.

3. Low solvent content in wet flour, reduced load on the dissolution of wet flour.

4. Higher micelle concentration, which reduces the evaporation load.

5. Improving the quality of crude oil after production.

6. Increase the production of peeling equipment. The oil seed extruder requirement is not high with respect to the thickness of the flakes, which means that the thickness of the flakes is properly reduced in order to increase the performance of the peeling machine.

7. Reduce energy consumption during solvent extraction.

The principle of the rice bran expander:

The oil material is squeezed, heated, cut and rubbed into the cavity of the extruder of the machine, and mixed, steamed, gelatinized by injection of direct steam, the pressure in the extrusion cavity reaches 1.4-4.0 MPa, the temperature reaches 110-120º C, at the exit from the head the dies suddenly drop to normal pressure and temperature, the vapor evaporates sharply, the oil leaves the seed chamber to the outside, and an extruded material with countless minus holes and cracks is obtained. And thanks to such extrusion effects, the penetration of solvent through the cells and the penetration of oil from the cells become easier, therefore, the extraction and desolventing process becomes more efficient, the specific gravity of the material increases by about 30%, therefore the production capacity of the extractor is also raised. The residence time of the material in the extruder is less than 30 seconds, so damage to the contents of the material is negligible, which helps to protect the quality of the material.

We welcome your further inquiry, expecting to provide you with a complete solution. For various oilseeds, technological equipment is changing. We can help you design the whole vegetable oil production line according to your material and final product. If you want to know more about the rice bran extruder, please feel free to contact us.
