The oil press equipment currently on the market is mainly divided into cold pressing and hot pressing. The use of different production processes has a direct impact on oil yield and profit. Therefore, when the user chooses the oil press equipment, whether to choose cold pressing or hot pressing requires specific analysis. Today, Benteng Machine will help you understand the main difference between hot and cold oil press equipment, so that users can make better choices.
The main difference between cold pressing and hot pressing of oil press equipment:
1. Oil output rate. In the actual production process, the higher the oil yield, the higher the profit that users can create. The oil output rate of cold pressing is significantly lower than that of hot pressing. This is because the hot pressing uses heating oil, which improves the oil yield of the oil.
2. Pressing process. Different pressing processes are used for hot pressing and cold pressing. The cold-pressed raw materials have been carefully selected, mainly to avoid the influence of moldy oils. Cold pressing needs to be crushed to increase the oil yield. At the same time, it also needs to be pressed twice and pressed three times. Cold pressing means that the oil can be pressed without being cooked in a wok. The temperature of cold pressing is mainly controlled at 65 degrees. Hot pressing generally requires only one pressing. It is mainly composed of pressed snails and pressed strips. Basically, the raw material can have a good oil yield in one pass. The temperature of hot pressing is between 120-130 degrees.
3. Raw material selection Cold pressing is mainly for special raw materials, mainly olive oil, linseed oil, safflower seeds, etc. Hot pressing is suitable for most oil crops, such as soybean, rapeseed, cottonseed, peanut, sesame, etc.
4. Nutritional value Cold pressing mainly does not damage oil cells, promotes protein denaturation, and reduces oil viscosity. At the same time, the hair oil is light in color and has less impurities. The nutritional value of cold pressing is higher. The flavor of the oil is retained. Cold pressing has a low smoke point and unstable water content, so it is not conducive to long-term storage. The nutritional value of hot pressing is lower than that of cold pressing because the oil is fried. The hot-squeezed oil will be squeezed after being cooked. The oil tastes good and fragrant.
By analyzing the difference between hot pressing and cold pressing. In the process of selecting oil press equipment, users can analyze their own raw materials and oil yield. Choose the equipment that suits you. More oil press equipment related content.
