The closed drum seed-frying machine is the preferred auxiliary machine in the oil extraction process configuration. Three parts press and seven parts fry, so it is more important to improve the oil press technology and choose what kind of frying machine; The closed seed-frying machine uses the steam generated by the moisture of the oil to steam the oil while frying, soften the plant cellulose, prevent the high temperature carbonization of the oil, reduce the amount of slag in the process of oil extraction, improve the oil yield, and make the oil clearer. It can control the same temperature for the same raw materials, and it will not worry about the phenomenon of oil frying for a long time, reducing the hardening degree of the seed-frying technology. With the closed seed-frying pan, everyone is an expert in oil extraction.

The closed drum seed-frying machine uses the steam generated by the oil itself after heating to steam the oil while frying, soften the plant cellulose, prevent the high temperature carbonization of part of the oil, reduce the amount of slag in the oil pressing process, improve the oil yield, and make the oil quality clearer. Closed frying pan is an essential equipment in oil extraction.

The closed drum seed-frying machine is composed of a frame, a hopper, a cylinder, a fire shield, etc., and adopts an advanced drum horizontal structure. The drum is evenly heated and has a thermal insulation function. The drum keeps rotating during operation to make the oil stereoscopic stir fry and avoid sticking to the pan.

Precautions for closed drum seed-frying machine:

1. The motor shall be started to make the cylinder rotate to avoid local heating of the cylinder during ignition;

2. The cylinder can be preheated to about 50 ℃ to feed and fry seeds. The time of material frying depends on the size of firepower and one-time loading, which is generally 20-50 minutes.

3. Judge whether the material can be discharged (sample from the inlet). If the material can be discharged, open the outlet baffle, and the material will go out in succession;

Example of frying sesame, peanut, rapeseed and other oils with closed drum seed frying machine:

1. Sesame: it is better to fry the seeds into brown before pressing. (observe the color of the seeds and pinch the skin with your hands), there is cracking phenomenon. When frying the seeds, keep the two ends of the fire low and the middle of the fire high. The pressing temperature is 140-150 ℃.

2. Rapeseed: first use high fire to fry the rapeseed until it is hot and there is a noise, and then use low fire to fry the rapeseed until it is pinched and turned brownish red. When pressed, the rapeseed temperature is 120-130 ℃, and the moisture content is 1-1.5%.

3. Peanut kernels: Before frying seeds, soak the peanut kernels once. During the process of frying seeds, fry the kernels until they are eight mature, and knead them by hand to separate the kernels and skins. The kernels are light yellow, with a temperature of about 130 ℃ and a moisture content of 1-2%.

4. Cottonseed kernel: before pressing, fry the oil until it is light yellow, the temperature is 120-130 ℃, and the water content is 1.5-2.5% (the water content in the south and the north is different, and properly control the water content).

Note: When frying peanuts and rapeseed, the frying pan needs to be shelled before frying, which can increase the oil yield of peanuts and rapeseed.
