In the process of edible oil refining, loss is an important problem faced by production enterprises. Reducing loss can not only improve the utilization rate of raw materials, but also reduce production costs and improve economic benefits. The following are some methods and strategies that can effectively reduce the refining loss of edible oil:

1. Optimize the process flow

The edible oil refining process includes degumming, deacidification, decoloration and deodorization, and raw material loss may occur in each link. By optimizing process parameters, such as temperature, pressure and reaction time, unnecessary loss can be reduced. For example, in the degumming process, the loss of oil can be effectively reduced by selecting the appropriate phospholipid remover and controlling the reaction conditions.

2. Improve equipment efficiency

The performance of refining equipment has a direct impact on the loss. Using efficient centrifugal separator or filtration equipment can reduce the loss of oil in the process of impurity separation. In addition, regular maintenance of the equipment to ensure that it is in good working condition will also help to reduce the loss.

3. Control the quality of raw materials

Raw material quality is an important factor affecting refining loss. Selecting high-quality raw materials, especially oilseeds with less impurities, can reduce the need for additional treatment of raw materials in the edible oil refining process, thus reducing the loss. In addition, oxidation and pollution should be avoided when storing raw materials to maintain their freshness.

4. Reduce by-product wastes

In the edible oil refining process, some by-products, such as phospholipids and soapstock, will be produced. If these by-products are not handled properly, they will lead to additional oil loss. The overall loss can be further reduced by improving the by-product treatment technology, such as recovering phospholipids or extracting oil from soapstock.

5. Strengthen operation management

The operating skills and management level of employees also have an important impact on loss control. By training operators to familiarize them with equipment operation and process flow, the loss caused by human error can be reduced. In addition, the establishment of strict production management system, monitoring and recording of each link, can find problems in time and solve them.

6. Apply advanced technology

The development of modern technology provides more possibilities for reducing the refining loss of edible oil. For example, the use of enzymatic degumming can reduce the loss of oil caused by traditional chemical methods; Using membrane separation technology can separate impurities more efficiently and retain more oil.

To sum up, reducing the loss in edible oil refining process needs to start from many aspects, including optimizing technology, improving equipment performance, controlling raw material quality and applying advanced technology. Through systematic improvement measures, enterprises can not only significantly reduce production losses, but also improve product quality and provide strong support for the promotion of market competitiveness.
