Oil Cake Extraction Equipment:

The stainless steel fixed grid plate extractor is one of the modern extraction equipment, which retains the advantages of small power consumption, reliable equipment operation, long service life, convenient maintenance, and good extraction effect compared to the traditional false bottom flat rotary extractor. It also has the advantages of high output, simplified structure, fewer operating faults, and good extraction effect.

vegetable oil extraction complete set equipment is a continuous oil production equipment, which utilizes the action of selected organic solvents to dissolve oil. Through soaking and spraying, the oil is extracted from oil cakes or oil seeds, which can be used for the extraction of rapeseed, peanut, cottonseed, sesame, and all other oil crops and pre-pressed cakes. It can also be used for the single extraction of certain oil crops (such as soybeans).

The main advantages of Hongyang's extraction method for oil production: firstly, the oil yield is high. Currently, in China, the oil yield of oil cakes using pressing and screw methods is above 5%, while the oil yield of oil cakes using extraction method is below 1%. Moreover, the meal extracted from soybeans in one-time extraction is of high quality due to the low temperature, high protein content, and high utilization value, which can be widely used as food raw materials.

Hongyang's extraction method for oil production has the advantages of low processing cost, high oil yield, high labor efficiency, low labor intensity, safe and reliable equipment, convenient operation and maintenance, and good environmental hygiene conditions, which other oil production methods can not catch up with.

Main Features:

1. It is the most simplified structure among similar extractors.

2. The fixed grid plate replaces the false bottom, reducing the number of moving parts and thus reducing faults, improving the safe operation rate, and ensuring reliable operation.

3. It has a "self-cleaning" effect and does not require shutdown for cleaning the grid plate.

4. It can increase the extraction time of the material, reducing the residual oil rate in the meal.

5. It can increase the loading factor and improve the output.

Process Flow:

The pretreatment material is conveyed by a scraper conveyor into the sealed auger in the extraction workshop, falling into the flat rotary extractor. It is then sprayed with solvent or mixed oil for extraction. After draining, the wet meal falls into the meal hopper and is conveyed through the scraper conveyor and sealed auger into the steaming and de-solventing machine. After removing the solvent through steaming and drying, it is transported to the finished meal warehouse. The concentrated mixed oil filtered by the extractor flows into the mixed oil tank, then enters a long tube evaporator to separate the solvent steam. It then flows into a second long tube evaporator for further separation of solvent steam. After separation, it flows into the stripping tower to remove residual solvent. The obtained crude oil enters the crude oil tank and is sent to the refining workshop. The solvent steam from the long tube evaporator, the second long tube evaporator, the stripping tower, and the Hongyang brand flat rotary extractor is introduced into the condenser for condensation. The condensed liquid flows into the separator for water separation, and the separated solvent returns to the solvent circulation warehouse. The wastewater from the separator and the solvent circulation warehouse flows into the boiling water tank for boiling and then to the water seal pool. The free gases from the top of each device converge into the after-condenser for condensation, and the non-condensed gas enters the absorption tower for further solvent capture.
