What are the factors that affect the oil yield of peanuts?

For the processing of peanut oil, the basic purpose is to extract the oil in the peanut fully and keep the oil yield at a normal or even abnormal level. However, there are always some factors that affect the oil yield of peanuts, resulting in a large reduction in its oil output, such as the impurity content in peanuts, the process conditions of the oil press (pressing moisture and pressing temperature, pressure, pressing time), and so on, which are directly or indirectly affecting the oil output of peanut oil processing equipment. Understanding the factors that affect the oil yield of peanuts is critical to optimizing production processes and ensuring consistent product excellence. Let's delve into these factors and see how Henan Glory solves these problems.

The quality and variety of peanuts

The quality and variety of peanut play an important role in the oil yield of peanuts. Different peanut varieties have varying oil contents. Before pressing, the level of impurity content in peanut directly affects the oil yield of peanut oil processing equipment, and even affects the quality of finished oil. Just collected in the shell of peanuts are unavoidably mixed with sand, stones, and other impurities, the existence of shell and impurities is bound to absorb part of the oil residue in the cake meal, reduce the oil yield. In response to this, Henan Glory Company is equipped with sheller and cleaning equipment in the peanut pretreatment section to clean and screen peanuts, remove impurities in peanuts, affect the oil yield at the same time, but also to reduce the wear of equipment, extend the service life of equipment.

Oil processing conditions

Processing technology is another critical factors that affect the oil yield of peanuts. Advanced extraction equipment and refined techniques can significantly boost the oil extraction rate. Poor or unstable control of water and temperature will affect the oil yield of the equipment. Several tests have also shown that the water content of pressed embryo can not be lower than the cake forming limit, and the appropriate range of pressed temperature is 110~130°C. If the water is too high, it will cause the embryo to produce clumps and affect the oil production. On the contrary, the moisture is too low, the material embryo is pressed into powder; Similarly, too high temperature will cause the oil color and even increase the amount of fuel loss, affecting the quality of oil; On the contrary, when the temperature is too low, good pressing conditions cannot be formed. Therefore, the oil yield can be improved by controlling the pressing water moisture and pressing temperature of the embryo.

The essence of the oil press is to apply pressure to the embryo to remove the grease, and the pressure of the press chamber of the oil press will directly affect the oil yield of the equipment. Press pressure is closely related to cake thickness, feed quantity and pretreatment. Therefore, maintaining a normal and stable pressure can effectively ensure the oil yield of the equipment.

There is also a certain relationship between pressing time and oil yield. Under normal circumstances, the pressing time is too long, the heat loss is more, but affect the oil yield and production capacity; The pressing time is too short, it can not ensure that the oil is fully extracted. Therefore, under the premise of realizing the oil yield, the press time should be controlled as reasonably as possible.

Furthermore, the processing site environment and standardized operation of peanut oil equipment will also affect the oil yield of peanuts. The extraction process is a balance of factors, including peanut quality, moisture content, and operator skill. Henan Glory Company's experienced technicians ensure that every step of the extraction process is meticulously controlled to achieve optimal oil yield.
