How much does an oil press cost? What is the working principle of oil press?
Oil equipment manufacturers for new and old customers to provide a variety of grain and oil processing machinery and equipment related to the issue of free advice: oil presses, oil refining and purification equipment, oil extraction equipment, refining equipment, oil processing, purification equipment, lard processing equipment, butter refining equipment, chicken and duck oil refining equipment, animal oil refining equipment, animal oil refining equipment, puffing leaching equipment, wheat milling equipment, rice processing equipment, grain drying equipment and other related issues. equipment, grain drying equipment and other related issues. First, what is the working principle of the oil press? 1. With the help of mechanical force, the oil from the oil material will be squeezed out of the oil extraction method is called pressing method of oil extraction. 2. According to the size of the pressure on the press material and the depth of the press oil extraction, the press method can be divided into a press and pre-pressing. The first pressing, also called full pressing, requires the pressing process to extract as much oil as possible from the press material, and the residual oil in the cake after pressing can reach about 5%. Pre-pressing only requires that about 70% of the oil in the press material be extracted during the pressing process, and the pre-pressed cake is then subjected to solvent leaching for oil extraction. According to different pressing temperatures, oil extraction from pressing can also be divided into hot pressing and cold pressing. Hot pressing has a high oil yield, but the protein of the cake is deeply denatured and is generally used as feed. The oil yield of cold pressing (temperature below 80°) is lower, but the degree of protein denaturation in the cake is small, light color, and can be used as raw material for edible protein powder….
