rapeseed oil extraction equipment

Rapeseed oil extraction equipment

1. Extraction Section Processing :

(1) The material (for pretreatment) is sent to rotary extraction by the scraper conveyor. The material will extracted by the solvent or mix oil. After this step, we will get meal and mix oil.

(2) Meal is sent to toaster. Through the toaster, the solvent in the meal will separate from the meal. The solvent goes to condenser and is recycled to rotary extraction.

(3) After the mix oil from the rotary extraction enters into 1st evaporator and 2nd evaporator, most of the solvent in the mix oil is separated.

(4) The mix oil from 2nd evaporator goes to stripping tower and almost all the solvent is separated. From the stripping tower, we can get crude oil and solvent. The solvent is sent to condenser and is recycled to rotary extraction.

Main process description of Rapeseed Oil Extraction Plant :

Cleaning process:

Adopt the magnetic separation removing iron miscellaneous and vibration sieve removing broken clear, rice Xi, etc.

Expanding process:

Adopting the expander 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 mateial grain, and increases the materials bulk density, then improve the permeability and leaching rate which solvent reacts to the material.

Drying process:

The puffed rice bran contains about 12% water, and the best moisture for leaching process is 7-9%, therefore, there must be effective drying means to achieve the best leaching moisture.Adopting counter-current dryer can make water and temperature meet with follow-up process requirements, and improve the oil yield, as well as oil quality.

Process feature:

1.Different combinations of process can process various oil plants in one workshop.

2. Extrusion treatment is used for raw materials with hard extraction, large-sized powder, and large capacity, which can reduce residual oil and solvent consumption, and increase the capacity by 50-80%.

Features of Oil Extraction Plant for Oil Extraction Machine :

1. Adopt stainless steel fixed grid plate and increase the horizontal grid plates, which can prevent the strong miscella from flowing back to the blanking case, so as to ensure good extraction effect;

2. The rotocel extractor is driven by rack, with unique rotor of balanced design, low rotating speed, low power, smooth operation, no noise and quite low maintenance cost;

3. The feeding system can adjust the rotating speed of airlock and main engine according to the feeding quantity and maintain a certain material level, which is beneficial to the micro negative pressure inside the extractor and reduce the solvent leakage.

4. The advanced miscella circulation process is designed to reduce the fresh solvent inputs, reduce the residual oil in meal, improve the miscella concentration and save energy by reducing the evaporation capacity.

5. The high material layer of the extractor helps to form immersion extraction, reduce the meal quality in miscella, improve the quality of crude oil and reduce the evaporation system scaling.

Automatic Control System of Oil Extraction Plant

Our company has applied the automatic control system with advancedness, security, reliability into the pretreatment, extraction, refining and fractionation in large oil plants. For its application in automatic control system, it can control the production in the entire workshop and monitor the operational status of each device by controlling the computer terminals in the room. One person only can operate the entire workshop, with efficient production management. It has reduced the production cost greatly and improved the management efficiency.
