The specificaitons of soybean oil expeller

 (1).Cleaning:Remove the raw material peanut in various impurities, such as: iron, stones, clump, such as the plant leaf, clean up after the raw material peanut impurity content should not exceed 0.2%.

(2).Crushing:Oil seed is crushed into 6-8 pieces. In order to meet the requirements of crushing, the peanut is suitable for crushing with the moisture of 7% to 12%.

(3). Softening: The purpose of softening is to adjust the moisture and temperature of oil, and make it soft.

(4).Flaking process: Rolling raw material into flakes, and the purpose is to increae surface area, destroy the peanut cell tissue, shorten the way of oil out from cake.

(5).Drying:Adjust moisture of rice bran to meet the requirement of going to extraction process. 

(6).Cooking process: use steam cooking, inject direct steam and cook the flakes to meet the requirement of oil press.

(7). Pre-press: Press the flakes to leave about 16%-18% in the cake. The cake will go to extraction process.
(8). Second oil press: Press the cake till the oil residue is about 5%.

Main process of soybean oil expeller: 

1. Solvent pumps: continuously spray solvent to the rotary-type extractor.

2. Roary extractor: Spray and soak the pre-pressed cake with solvent so that oil fats can be

diss-olved in solvent(form miscella). After processing, you can get wet meal and miscella (mixed oil).

3. DTDC: usd to separate the solvent from the wet meal.

4. Miscella tank 1st: pump the miscella (oil with solvent) in to the miscella 1st , then add saline water to it. The phospholipid in the miscella will react with the saline water, at last the reactant precipitate,

reaching the goal of purifying.

5. Miscella tank 2nd: the purified miscella will be pumped into it.

6. Miscella stripping: it will remove the remaining solvent in miscella. And the solvent will be discharged to condenser for recycling.

7. Condensers: used to cooling the solvent gas separated from the wet meal and miscella for recycling.

Advantage of soybean oil expeller                                     

1. Our products have the high quality and high performance.we use the stainless steel instead of the carbon steel.

2. We purchase directly from the manufacturer for guaranteeing the quality.

3.Our welding worker should get the certificates. and our electric machines all imported from 

Germany. And more other advantages we will talk in our specific condition.

4. Adopting negative pressure evaporation can ensure excellent oil quality.

5. All equipments are provided with exhaust gas absorption systems with excellent absorption effect.

6. Full energy-saving design utilizes heat energy for many times and saves steam consumption.
