BV CE certification cotton seed oil extraction mill

Cotton Seed Oil Extraction Equipment

Rotocel Extraction

Process Features of Qi'e Rotocel Extraction:

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.

6. Specially suitable for the extraction of various pre-pressed meals.

Towline Extractor

Towline Extractor Advantages:

1) The material is divided into several independent units on the material bed, which can effectively prevent miscella at all levels from fleeing hither and thither on the material layer and ensure the concentration gradient between several sprays.

2) Immersion area appears in each lattice, which can help achieve better immersion effect.

3) The chain box is supported by track and can prolong the service life of screen deck by not touching it.

4) The towline extractor is driven by world BV CE certification cotton seed oil extraction mill double-shaft hydraulic motor, with balance force, reliable operation and less maintenance cost.

5) Specialty suitable for the extraction of high oil and high power materials, and better immersion effect can be expected for ordinary oil plants.

Wet Meal Desolventizing Process

Desolventizer toaster advantages:

a) Passivate and damage the anti-nutritional components such as the urea enzyme and trypsin in the meal, and improve meal value in use.

b) Control the protein denaturation degree in the meal , and improve the NSI index effectively.

c) It can better regulate the color, flavor and taste of the meal.

d) It can better reduce residual solvent in the meal and regulate the meal moisture, so as to guarantee the minimum solvent consumption and safe use of the meal.

Negative pressure evaporation process

The liquid from the extractor is the miscella containing grease and oil, which can be separated out according their different vaporization temperatures. Our company mainly uses BV CE certification cotton seed oil extraction mill evaporation technology, and it can reduce solvent leakage and consumption. The separated solvent vapour is cooled and recycled back to the extractor for reuse, which can improve the solvent efficiency.

BV CE certification cotton seed oil extraction mill Evaporation Advantages:

a) BV CE certification cotton seed oil extraction mill evaporation features high efficiency, thorough de-solvation and low solvent consumption in crude oil

b) Use the second steam of desolventizer toaster and remaining steam from steam jet pump as the heat source of the first steam, which can save energy, reduce the condenser configuration area and save investment

c) Due to the low temperature of the steam, the crude oil features light color, good quality and low residual solvent.

Solvent condensation & recovery process

Solvent condensation system combines with evaporation system closely, and evaporative condenser and steam stripping condenser all work under negative pressure. Non-condensable gas enters the energy saver from the shell of the first evaporator. In energy saver, noncondensable gas exchanges heat with condensate from the evaporative condenser. Finally, the condensate temperature discharged from energy saver is increased, and the solvent separated from water goes to solvent holding tank. The high temperature makes it unnecessary to be reheated for the recycling, so as to save energy. Noncondensable gas from energy saver enters desolventizing condenser, in which a great deal of gas is condensed, and the tail gas is discharged into the final condenser. The solvent gas from the extractor enters extraction condenser, and the noncondensable tail gas enters the final condenser. For the free gas in final condenser, diversion box, holding tank, underground solvent library and miscella tank, cool them with low temperatured cold water to recycle most of solvent gas. The tail gas with little solvent goes to paraffin recovery process.

Zhengzhou Qi'E Grain&Oil Machine Co.,Ltd 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.
