The production process of soybean oil mainly has two types: raw pressing and cooked pressing. Among them, soybeans are mainly squeezed. Raw oil is sent to the oil press for squeezing without heating or low temperature before the oil is squeezed. The step of frying seeds is omitted.
However, it takes twice during the squeezing process to squeeze it out. So what are the advantages of raw soybean oil?
1. Utilization of soybean cake. Rapeseed cakes and peanut cakes are generally used as feed. The price is generally around 1 yuan per catty. Raw pressing can ensure that the soy protein is not destroyed. Make artificial meat and yuba. Therefore, the price of soybean cake is more than two yuan per catty.
2. The raw oil ensures that various nutrients are not destroyed, the content of unsaturated fatty acids is high, and the residues of harmful substances such as acids, alkalis, heavy metals and cholesterol are eliminated, so that the oil is clear, the smell is fresh, and the original taste.
3. Raw squeezing avoids the seed frying process. Frying seeds requires burning coal, wood and gas, and the overall operation is relatively cumbersome. Avoiding the quality of fried seeds will also affect the oil yield. Raw squeezing does not require frying seeds, it is directly squeezed.
Therefore, the oil output rate is relatively stable. The operation process is also relatively simple. At present, the commonly used squeezer models on the market are 130 type and 1.50 type. The green press is equipped with an automatic cycle feeder. Feeding can be realized directly. Therefore, the operation process is relatively simple and easy.
