Soybean oil extraction machine uses the function of organic solvents to dissolve oil. After soaking and spraying, it extracts oil from soybeans. It can also be used for pre-pressing and extraction of oil crops such as rapeseed, peanuts, cottonseed, and sesame. The oil yield of the soybean oil extraction equipment is higher than that of oil extraction by pressing. The residual oil content in soybean meal after extraction by extraction is less than 1%. In addition, the soybean meal extracted once has a low temperature, high protein content, good quality, and high use value, and can be widely used as food raw materials.
In production, the oil content of cake meal in the soybean oil extraction machine will also be affected by various factors. The reasons that affect the residual oil content of the extraction equipment are as follows:
1. The nature of the embryo: whether the embryo of the first extraction is controlled to be less than 0.3mm in thickness, less than 10% in moisture, whether it is steamed thoroughly, whether there is "white heart", and how the powder degree is.
2. Extraction temperature: Appropriate extraction temperature can play a role in diffusion, which enhances the molecular thermal motion and reduces the viscosity of oil and solvent, thus increasing the extraction speed or reducing the residual oil rate in the meal within the same extraction time.
3. The contact time (immersion or spraying) between the solvent and the oil: that is, the extraction time. The extraction time should ensure that the oil molecules have enough time to diffuse into the solvent, but too long extraction is not acceptable. A balance should be achieved between the equipment capacity and the residual oil content of the dry meal according to the actual situation.
4. Influence of solvent ratio and mixed oil concentration: If the solvent ratio is too small, the mixed oil concentration will be too high, and the extraction effect will not be achieved or partially achieved, which will increase the residual oil content in the dry meal. However, if the solvent ratio is too large and the mixed oil concentration is too low, it will increase the burden on the evaporation system and affect the production capacity of the entire system.
The above are the factors that affect the oil content of soybean meal after extraction by soybean extraction equipment. The residual oil content in the meal will reduce the manufacturer's profit. Paying attention to the above matters can reduce the residual oil in the meal as much as possible, allow the oil to be fully extracted, save costs, avoid waste, and thus ensure our economic interests.
