Product Description

Deacidification of palm oil refining machine :This part adopt alkali refining method, that is use alkalis (NaOH) to neutral the free fatty acid in oil, during this process it will produce soapstock, then separated from the oil by setting several hours. NAOH solution, not only neutral free fatty acid, also can act with other matters protein, mucus, phospholipid, pigment. After settling, release the soapstock from the tank bottom. Adding hot water to rinse, remove off the leftover lye, soap and some unhydrated phospholipid in the oil. Finally pumping out soapstock from the tank bottom.

Deodorization and Dehydration of palm oil refining machine :Usually ,there are some odors in the crude oil, it affects the quality of the edible oil . About our refining process, we usually use the direct steam to take odors away in the vacuum condition . General speaking there is about 0.5% water in the alkali refined oil, in the deodorization pot, thetemperature is very high, it also can finish the dehydration section.

Process Features of 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.

Advantages Of Towline Extractor:

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 leading 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 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 vacuum 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.
