Soybean oil machine

Soybean oil machine raw grain cleaning process and description

Measurement process: The domestic advanced equipment configuration is used to adjust the flow, ensure the production stability and measure the total production, and can achieve the purpose of cumulative measurement, instantaneous measurement and cost accounting. Accurate measurement and high precision.

Cleaning process: use magnetic separator to remove iron impurities; vibrating cleaning screen to remove large impurities, straw, etc.; specific gravity remover to remove heavy impurities such as stones and bricks; Ensure workshop hygiene and remove light impurities.

Preliminary processing process and description of soybean oil machine raw grain

Conditioning and tempering process: The low-denaturation drying tower and fluidized bed are used for rapid drying, which can not only ensure the peeling rate of the peeling process and increase the protein content, but also ensure that the soybean protein is not denatured.

Dehulling process: use a dehulling machine and a husk separating sieve to dehull the soybeans to increase the protein content of the soybean meal.

Softening process: Use a vertical softening pot to heat soybeans to 50-70 °C to fully soften them, improve the plasticity of soybean raw materials, and make the embryos rolled by the flaking mill thin and not broken, thereby improving the leaching effect. At the same time, the skin and kernel are further separated during the stirring process to facilitate protein stability during low temperature production.

Technological process and description of raw grain deep processing of soybean oil machine

Crushing process: When the temperature is high, the double-roll tooth roller crusher is used to crush the soybeans into uniform 4-8 pieces. Avoid excessive crushing of soybeans and oversized watercress. When the temperature is low, it is crushed by a flake peeling machine to obtain complete kernels, skins and navels, which are further screened to separate the three materials.

Rolling process: Hydraulic tight-roll rolling mill is used to better destroy the oil cell tissue, so as to ensure that the rolled billets are thin and uniform, tough and powdery.

Bean shell drying process: Considering the high moisture content of the raw material and the invariability of soybean protein, a low-temperature airflow dryer is used to dry the embryo pieces to a suitable moisture content for immersion.

The complete set of pretreatment equipment for soybean oil machines we provide has the following advantages: all continuous and mechanized operations. Under the premise of guaranteeing advanced process indicators, the process is simple, equipment investment is reduced, failure rate and maintenance costs are reduced, space is fully utilized to save land, and gravity is fully utilized to save energy.

Pretreated soybean flakes→Extractor→Desolvation device→High temperature or low temperature soybean meal

Mixed oil evaporation system → soybean crude oil to refining workshop

2. Description of the oil extraction process of soybean oil machine

2.1 Extraction process

The pretreated soybean blanks are sent to the extractor by the feeding scraper conveyor. The material runs a circle from the feeding port to the discharging port in the extractor, and is sprayed through the mixed oil with decreasing concentration. and soaking, and finally sprayed with fresh solvent, after passing through a drip drying area, it is continuously fed into the wet meal scraper. After the thickest mixed oil is filtered by the filter machine, it is pumped into the mixed oil tank with a mixed oil pump, and then sent to the first long-tube evaporator by a steam feed pump.

2.2 Extraction wet meal desolvation process

a High temperature part: the wet meal containing dissolved water comes out of the extractor, and the wet meal scraper is passed through the material sealing and auger, and then sent to the pre-stripping of the desolventizing machine. The desolventized wet meal enters the stripping layer; direct steam is introduced into the bottom to remove all the solvent, and at the same time part of the steam condenses in the meal, the moisture of the meal will increase, and the desolubilized meal will be quantified by the rotary valve and fall to the bottom. The drying layer is dried, and finally the material is controlled by the automatic feeding gate, and then sent to the meal warehouse by the meal scraper.

b Low temperature part: the wet meal containing dissolved wet meal comes out of the extractor, and the wet meal scraper is sent to the desolventizers A and B through the material sealing auger for desolvation, and the desolubilized low temperature meal enters the meal warehouse for screening. and packaging, wherein, the A tube is heated by solvent steam, and the B tube is heated by indirect steam.

2.3 Evaporation and desolvation process of mixed oil

Total negative pressure evaporation is used for the first steaming, second steaming, stripping and desolvation of the mixed oil. Use steam jet pump to pump negative pressure. The steam and solvent mixture ejected by the steam jet pump enters the cooking tank for separation.

After the mixed oil is precipitated in the mixed oil tank, it enters from the mixed oil tank, the first long tube evaporator tube side; the evaporated solvent enters the vacuum condenser through the separation chamber.

The mixed oil after the first evaporation enters the second long-tube evaporator for evaporation, the shell side is heated by indirect steam, and the evaporated solvent gas enters the vacuum condenser after passing through the separation chamber.

The mixed oil enters from the top of the stripping tower into the disc in the tower, and descends layer by layer, while direct steam is sprayed at the bottom to remove the solvent, and the top outlet is connected to a vacuum condenser.

2.4 Solvent cooling and water separation

The condensate of the condenser is collected into the liquid collecting tank respectively, and enters the water distribution tank, and is recycled after water separation. The extractor, the water separator, the free gas of the solvent storage and the free gas of the cooking tank are collected together, enter the tail gas balance tank, and then go to the last condenser, and the uncondensed gas from the last condenser enters the paraffin absorption tower.

2.5 Exhaust gas recovery device

The uncondensed gas from the tail gas balance tank enters the final condenser to recover the solvent. The final condenser does not condense the gas and enters the paraffin absorption tower to recover the residual solvent. The free gas is discharged into the atmosphere by the exhaust fan through the flame arrester.

3.3 Description of the oil extraction process plan of soybean oil machine

Extraction is the process of mixing the pretreated soybean germ flakes with a solvent and evaporating the solvent to obtain crude oil. The production process of the leaching workshop includes: leaching, wet meal evaporation, mixed oil evaporation, solvent recovery, etc. The complete set of process equipment for the leaching workshop we provide has the following advantages: "High quality products, energy saving and high efficiency."
