Almond oil, slightly yellow and transparent, has a fragrant taste. It is not only an excellent edible oil, but also a high-grade lubricating oil. It can withstand low temperatures below -20°C. It can be used as an important raw material for high-grade paints, cosmetics and high-quality soaps. It can also extract flavors and vitamins.
Since almonds are different from southern apricots (sweet almonds) and northern apricots (bitter almonds), there is still sweet almond oil. Almond oil is rich in protein, unsaturated fatty acids, vitamins, inorganic salts, dietary fiber and trace elements required by the human body. It has the effects of moisturizing the lungs, strengthening the stomach, and replenishing physical strength. Its amygdalin is a natural anti-cancer active substance.
Ⅰ、Production process of almond oil pressing equipment:
Almonds → cleaning → pressing → filtering → cold pressing oil → going to the refining workshop
1. The whole set of almond oil equipment developed by Zhongxing Grain And Oil Machinery is mainly cold pressing of almonds, but also hot pressing.
2. Using cleaning, removing impurities, and cold pressing technology, the pressed oil has a light color, low acid value and high nutritional value.
3. The benzopyrene index that customers are more concerned about is solved in the pressing process, and the nutrient content is fully maintained.
4. The oil press adopts a hydraulic cold press. The output of this machine is adjustable, easy to operate, and high in production efficiency.

Ⅱ、Refining process:
1. Brief description:
This workshop adopts intermittent refining production technology. According to the different types 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 and 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)Process description:
① Alkali 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 at 60r/min for 5-10min, observe the formation and separation of soap particles after the reaction, and start to slowly heat up, change to slower stirring. It will increase by about 1°C every minute. It will increase by about 1°C every minute. When the temperature reached 65°C, the oil soap was clearly separated, the stirring was stopped, and the soapstock began to precipitate. It usually takes 4-6 hours to release the soapstock.
② Washing operation: After the soapstock 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 repeatedly 1-2 times, depending on the quality of the clear oil.
③ Decolorization 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 to stir for 10 minutes after the temperature reaches 100℃ 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 cooled 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℃, open the bottom of the steam directly to start distillation and deodorization, and start timing.
a. Deodorization time: 2-3h,
b. Deodorization temperature: 220℃-240℃,
c. Deodorization vacuum degree: above 755mmHg,
d. The whole process must be directly steam distilled.
