Screw Oil Press: Six Techniques To Increase Oil Yield
There are also tricks to increase the oil yield of oilseeds. How to increase the oil yield when the most popular screw presses are used to press peanuts, soybeans, sunflowers and other oils? Next, Ruian Every Machinery oil press tells you six techniques to increase oil yield!
1. It is necessary to select oil "sieve"
Before squeezing the oil, some branches, weeds, soil and other organic impurities and inorganic impurities in the oil must be "sifted out"! The reason for removing these impurities is because these impurities will quickly absorb grease after entering the oil press, which will reduce the oil yield, and will cause wear and tear to the screw press, and the quality of the pressed oil will deteriorate, and sometimes it will get stuck. Staying in the oil press causes equipment damage or malfunction. Therefore, the oil must be cleaned and screened, and the screening methods are: water washing, fan blowing, screening machine, etc.
2. Stir fry with oil is the key
Screw oil press: six techniques to increase oil yield
The oil that needs hot pressing must be heated before it can be squeezed. Therefore, the fried oil is generally an indispensable link in the pressing process of the screw press, and the purpose is to increase the oil yield. The temperature, time and moisture of the fried oil have different oil yields. This has been verified by experiments. The water content is not easy to be too high. Too much water will not only cause high oil yield and even cause no oil output. If the water content is too low, the output is not cake material but powder residue, and the oil yield rate is also extremely low.
3. Oil humidity needs to be controlled
The identification of oil humidity requires certain experience, which can be summarized as: touch, taste, and look. Respectively refers to: 1. Touch the oil with your hand, whether it feels astringent in your hand, and the fragrance of the raw material is pungent. 2. Pinch a few tablets and put them in your mouth to chew, the teeth feel hard and muffled. 3. Under normal circumstances, the moisture of oil crops can be distinguished by distinguishing the dryness and color of the crops. When pressing, it can also be distinguished by pressing conditions. Under normal circumstances, there is less oil residue on the outside of the squeeze ring of the screw press, and the oil output is relatively stable and clear.
4.pay attention to the machine temperature
In the process of oil squeezing, grasping the temperature of the screw press is also one of the keys to the oil yield. If a screw press passes through the continuous pressing equipment, the temperature will gradually rise, when it runs for too long You should rest for a while to prevent the machine from overheating, and when you first start pressing, you also need to preheat the machine. Use the previous oil cake or a small amount of oil to repeatedly press to make the oil press equipment temperature reach about 60 degrees.
5. the quality of oil should be distinguished
The quality of the oil also determines the oil yield. During the growth of the oil, the quality of the oil will be affected due to factors such as the climate environment and the degree of soil infertility. For example, the thick skin of some oils will reduce the oil yield. Peanuts, cottonseeds and other oils with skins can increase the oil yield.
6. oil pressing equipment
Quality determines quality, and you also need to pay attention when choosing a screw press. 1. Regular manufacturers have: the "three certificates" of qualification certificate, production license and promotion license are the qualifications that determine equipment manufacturers. 2. During installation and debugging, the structure, power and environmental conditions cannot be changed at will. 3. Spiral oil press needs to be checked regularly. If worn oil press parts are found, they should be replaced in time. Note that the model must be adapted. 4. The main shaft of the screw oil press directly affects the oil yield and must not be changed at will.
