1. Production process of peanut oil pressing equipment:
peanut fruit → shelling → shell and kernel separation → crushing → steaming and frying → pressing → filtering → peanut crude oil → going to the refining workshop
1. The complete set of peanut oil processing equipment developed by Henan Taixing Grain and Oil Machinery Co., Ltd. mainly uses hot pressing of peanuts, but also cold pressing;
2. Using dehulling, crushing, steaming and pressing technology, the pressed oil is light in color, low in acid value and high in nutritional value.
3. The benzopyrene index that customers are more concerned about is solved in the pressing process, and the nutrients are fully maintained.
4. The oil press adopts a screw press, which has a large output, low residual oil and a higher production efficiency than a single screw press.
2. Refining process flow of peanut oil processing equipment:
1. Brief description:
This workshop adopts the intermittent refining production process. According to the type and quality of crude oil, the process parameters can be adjusted and different refining methods can be selected to produce first, second and third grade edible oil; the process equipment we provide has the following advantages:
※ Flexible and convenient adjustment, even if the quality of raw materials changes slightly, it can still be produced normally;
※ Maximum use of heat, significant energy saving effect;
※ The fully enclosed production process avoids the oxidation of grease and ensures the high quality and stability of the product;
※ The appearance of the equipment is clean and beautiful, the equipment is guaranteed for a long time, and the life-long after-sales service;
2. Scale and raw materials:
The processing capacity is 1-200t/d, taking the daily processing of 3t soybean oil as an example
3, product index:
Soybean oil product oil meets the national standard GB19111-2003 standard (first and third grade)
4. Main economic and technical indicators:
4.1 Total installed capacity of refining workshop: 26.7kw; fuel and electricity consumption per ton 55kw/h
4.2 Water consumption: Circulating water 0.8t/ton oil
4.3 Consumption of auxiliary materials: caustic soda 3.5kg/ton oil; activated clay 20_40kg/ton oil
4.4 Refining consumption:
Neutralization alkali refining: When the crude oil W value ≤ 3%, it is 0.3+1.25×W%+0.3%
When the W value of crude oil is ≥3%, it is 1.35×W%+0.3%
Decolorization: Residual oil of clay residue≦25%
Deodorization: 0.3%+FFA%
5. Description of refining process
5.1 Process schematic diagram
5.2 Process flow description
①Alkali refining operation: adjust the oil temperature to about 60℃, then add 20-30Be lye (1kg caustic soda + 5kg water lye) within 5-10min, and stir for 5-10min under the condition of 60r/min, Observe the formation and separation of soap particles after the reaction and start to slowly increase the temperature, change to slow stirring, and increase by about 1°C every minute. When the temperature reaches 65°C, the oil soap separates obviously. Stop stirring and start to settle the soap feet. Generally, it is necessary Soap feet are released after 4-6h.
②Washing operation: After the soap stock is released, the oil is further heated to 75°C, and then hot water greater than 5% of the oil weight is added for washing. The water temperature should be 5-10°C higher than the oil temperature, and the water temperature should be 5-10°C higher than the oil temperature for easy emulsification; After adding water, continue to stir for 5 minutes, and then settle for 3-4 hours, release soapy water, and wash with water repeatedly for 1-2 times, depending on the quality of the clear oil.
③Decolorization operation: turn on the vacuum pump to make the vacuum ≧700mmHg; first suck the washed alkali refining oil into the decolorization tank, turn on the stirring and increase the temperature under the vacuum state, and continue stirring for 10 minutes after the temperature reaches 100°C to reduce the water content in the oil to 0.1% Below, inhale a small amount of decolorizing agent (white clay or activated carbon), the amount of addition depends on the oil product, generally 2%-4% of the oil amount, after stirring for 20 minutes, the temperature is reduced to about 90°C, the vacuum is broken, and the decolorization pump is turned on to filter The machine separates oil and soil to obtain decolorized oil.
④ Deodorization operation: The decolorized oil is sucked into the deodorization tank by vacuum. When the vacuum degree reaches 755mmHg and the temperature is above 150℃, the bottom is opened and the steam is directly distilled and deodorized, and the timing starts;
A, deodorization time: 2-3h,
B. Deodorization temperature: 220℃-240℃,
C, deodorization vacuum degree: 755mmHg or more,
D, the whole process must be directly steam distilled,
Three, dewaxing process
1. Brief description:
In the processed rapeseed oil, the waxiness inherent in the rapeseed oil can be separated from the oil through the dewaxing process, which enhances the nutritional value of the oil and improves the taste and quality of the oil.
The equipment characteristics of this workshop:
※ The operation is flexible and convenient, and the labor intensity is extremely low;
※ The production and production environment are clean and hygienic in a fully enclosed state,
※ All clean tap water is recycled, no sewage is generated or discharged, and it meets environmental protection standards;
