What machine does the sunflower oil mill plant need? What is the function of each machine?

Normally, the sunflower oil mill pant will use a series of machines, such as :cleaning machine, cracker, flaking roll, cooker, oil press, crude oil filter and so on. The first four machines are pretreatment, which are mainly used to prepare sunflower seeds to the best state before pressing, while the oil press is mainly used to extract sunflower seed oil. In order to get high quality sunflower seed oil, we also need to use filtering equipment to remove impurities in crude oil. Next, Henan Glory Company will introduce the specific functions of each machine to you.

Sunflower oil mill plant

Specific functions of each machine of sunflower oil mill plant are as follows:

1Cleaning equipment

Cleaning means removing impurities in sunflower seeds. Sunflower seeds may be mixed with various impurities in the process of harvesting, transportation and storage. Vibrating screen, magnetic separator and destoner are needed for cleaning. After that, the seeds shall not contain stones, iron impurities, sunflower seed skin, leaves, stems and other impurities. The content of total impurities should meet the national standard.

2.Cracker

Sunflower seed shells will absorb oil during processing, which will reduce oil yield. Sunflower seed shells can also cause equipment wear. In addition, if the shell content is high, the pressed oil will be dark, decolorization will require high temperature, which will damage the flavor and nutrients of the oil. Therefore, the shell content should not be too high. After cracking, the shell content of the oil will be reduced to less than 5%, and the kernel content of the separated shell will be less than 1%. Then kernel husk separator is used to separate kernels and shells.

3.Flaking roll

Flaking is a process of pressing sunflower kernels from granule into sheet by mechanical principle. The purpose of flaking is to destroy the cell tissue of sunflower kernels, increase their surface area, and provide convenient conditions for cooking, so that the oil can be separated smoothly during pressing or extraction.

4.Cooker

Cooking is the key to the production of sunflower seed oil. The aroma of sunflower seed oil is directly related to the temperature and time of cooking. When the temperature is low, the fragrance is weak. High temperature can increase the flavor of sunflower seed oil, but too high temperature or too long time will produce harmful substances and burnt taste. The key to produce high quality sunflower seed oil is to control the ideal temperature and time of cooking. A cooker is required here.

5. Oil press

The cooked sunflower kernels are delivered to a screw oil press for pressing. Through the external force of mechanical extrusion, the press makes the oil in sunflower seeds flow out, so as to obtain it. The residual oil rate of pressed sunflower seed cakes was about 6%.

6. Crude oil filter

Sunflower oil filter machine

The pressed sunflower seed oil contains a small amount of impurities, which need to be filtered out by a filter.

Through the above process, you will get the sunflower oil that meets the national standard, which can eat directky. If you want to get high-grade sunflower seed oil, you can also refine it.
