As the mechanical equipment for pressing oil crops, the press oil machine can be divided into two types: hot press and cold press. What are the differences, advantages and disadvantages between them? we will explain the hot and cold pressing of the oil press.
Cold pressing of oil press machine:
As the name implies, when the oil is not heated, it is directly put into the oil press for pressing after screening. This kind of pressing method is difficult to press clean at one time, and the oil cakes produced also have oil content. Some oil cakes that need to be pressed at one time have less oil content, but they do not have no oil at all. The advantage of cold pressing is that the color is relatively light, there will be no foam when pressing the oil, and there will be no sludge. The color is beautiful. The disadvantage is that the oil is not very fragrant, and it takes more than two times to press it clean.
Hot pressing of oil press machine:
Hot pressing is just the opposite of cold pressing. The oil plants are pressed after heating. This kind of pressing method can be pressed clean at one time. The oil cake produced is almost oil-free, so the oil cake is completely degreased and can be used to make oil-free material cake. The advantage of hot pressing is that the pressed oil is very mellow, and the hot added oil is more oily than the cold pressed oil. However, due to the fact that the hot pressed oil sometimes has a sludge pot, this should be noted during the pressing process. During the pressing process, the feeding should not be too hasty, and the feeding should be carried out according to the amount of oil squeezed.
