The cottonseed oil pressing production process is the production process of using cottonseed oil processing equipment to produce cottonseed oil through mechanical pressing. What cottonseed oil processing equipment is needed to complete the cottonseed oil pressing production line? Next,
1. Depilation
Before cottonseed oil is pressed, cottonseed lint should be treated well, so that the cottonseed lint content is less than 3%, so that it will not affect the production of cottonseed oil. If the lint content of cottonseed is too high, the peeling rate will be reduced, the separation effect of the kernel and the hull will be poor, resulting in a high hull content in the kernel. If cotton linters are mixed into oil, it will absorb oil and increase the total oil loss. In addition, cotton linters contain a large amount of wax, which makes the grease contained more waxy, which affects the quality of the grease. The cottonseed cake will also reduce the quality of the cake because of the short lint. Therefore, delinting is a key operation before cottonseed oil is pressed.
2. Clean up
The purpose of cleaning is to remove various impurities in cottonseeds, including light impurities, heavy impurities and wet impurities, to improve the purity of cottonseeds, and then improve the efficiency of cottonseed oil pressing. In addition, cleaning can reduce the damage of cottonseed oil processing equipment and extend the equipment. Service life. The cottonseed cleaning equipment is mainly a winnowing device.
3. Broken
The shell of cottonseed is relatively hard and must be crushed before pressing. There are two commonly used cottonseed crushing equipment: disc crusher and large crusher. The disc crusher is suitable for small-yield cottonseed shelling, and the price is economical; the large-scale crusher is suitable for large-yield cottonseed crushing, and the price is relatively expensive. After being crushed, the cottonseed can be pressed better without damaging the vulnerable parts of the oil press, and more importantly, it can increase the oil yield.
4. Steam and stir fry
The equipment used in cottonseed steaming and frying is a steaming pan, which can adjust the temperature and humidity of the cottonseed, change the internal structure and state of the cottonseed, and accumulate oil and improve the efficiency of cottonseed pressing.
5. Squeeze
The cottonseed oil processing equipment used in the pressing process is an oil press, and the pressing temperature requires 120°C. Wool cottonseed oil can be obtained by pressing. As pressed cottonseed oil contains impurities such as gossypol, it is necessary to refine the cottonseed oil.
6. Filter
Commonly used machines for filtering are plate and frame oil filter, vacuum oil filter and air pressure oil filter. The plate and frame oil filter is often recommended, which is cheap, easy to use, and clean.
7. Refining
Cottonseed oil refining is the process of removing various impurities in cottonseed oil through degumming, deacidification, decolorization and deodorization. The cottonseed oil processing equipment used is cottonseed oil refining equipment.
