oil pressing equipment

Peony seed oil is not only rich in nutrients, but also rich in unique biologically active substances. Among them,α-linolenic acid is the most basic and core substance in the evolution of human life, and It is also the main element for the synthesis of cell membranes. It can be used both internally and externally, and has the effects of promoting blood circulation and removing blood stasis, reducing inflammation and sterilizing, promoting cell regeneration, activating peripheral nerves, lowering blood pressure, lowering blood lipids, and losing weight.External use can beautify the skin, eliminate pigmentation, reduce wrinkles, and make the skin delicate, smooth and elastic. External use is also effective for the treatment of oral ulcers, rhinitis, arthritis, skin diseases (including acne, athlete's foot, exfoliation of hands and feet, blistering, eczema, redness, itching, etc.).

 

Ⅰ、Production process of peony seed oil pressing equipment:

Peony seeds → hulling → cleaning → pressing → filtering → cold pressing oil → going to the refining workshop

 

1.The whole set of almond oil equipment developed by Henan zhongxing Cereals and Oils 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 screw cold press, the output of this machine can be adjusted, easy to operate, and high production efficiency.

4	Hydraulic oil press	4	Used to squeeze peony seed oil
5	Filter	1	Used to filter a small amount of impurities in crude oil

 

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 After the reaction, the soap particles form a separation condition and start to slowly increase the temperature. Change to slow stirring, and increase by about 1°C per minute. When the temperature reaches 65°C, the oil soap separates obviously. Stop stirring and start to settle the soap feet. Generally, 4 Soap feet are released after -6h.

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,

Ⅲ、Dewaxing process

1. Brief description:

In the processing of peony seed oil, the wax inherent in the peony seed 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;

2. Description of dewaxing process:

deodorized oil → pre-cooling → crystallization and crystal growth → filtration and separation → refined oil
