Cold pressing of oil pres and Hot pressing of oil press:

Cold pressing of oil press:

When the oil is not heated, it is directly put into the oil press for pressing after screening. This pressing method is difficult to press clean at one time, and the oil cake also has oil content. Some oil cakes that need this type of one-time pressing have less oil content, but they are not completely free of oil. The advantage of cold pressing is that the color is lighter. When the oil is pressed, it will not frother, and it will not appear the phenomenon of silt pot. The color is better. The disadvantage is that the oil doesn't taste very fragrant. It takes more than two times to press it clean.

Hot pressing of oil press:

Hot pressing is just the opposite of cold pressing. The oil is pressed after heating. This pressing method can be pressed clean at one time. The oil cake produced has almost no oil content, so the oil cake is a completely degreased cake, which can be used when making oil-free material cake. The advantage of hot pressing is that the pressed oil is very mellow, and the oil added by hot pressing is more oily than that by cold pressing. However, due to hot pressing, sometimes there will be the phenomenon of silting the pot. During pressing, it should be noted that when pressing, don't worry too much about feeding, and cut the material appropriately according to the oil output of pressing.
