Peanut oil extraction method

Abstract

The invention belongs to the technical field of food processing, in particular to a peanut oil extraction method. A husking machine adopted in the extraction method comprises a shell removing box; tworotating shafts are rotatably connected in the shell removing box, wherein a part, locating in the shell removing box, of each rotating shaft is sleeved with a roller, and each roller is connected with one corresponding rotating shaft through a spline; a first ring and a second ring sleeves the roller between each roller and a first belt pulley, wherein the first ring and the second ring are rotationally connected with the rotating shaft, the first ring is fixedly connected with the roller, and the second ring is fixedly connected with the shell removing box; and each first ring is contactedwith the corresponding second ring, wherein the contact surfaces of the first ring and the corresponding second ring are chamfered surfaces. According to the invention, the contact surfaces of the first ring and the corresponding second ring are chamfered surfaces, and each second ring is driven to push the corresponding first ring, so that each roller can reciprocate along the axial direction ofthe corresponding rotating shaft while rotating, then peanut shells are rubbed while being extruded, and crushing efficiency of the rollers on the peanut shells is further improved.

Description

technical field [0001] The invention belongs to the technical field of food processing, in particular to a method for extracting peanut oil. Background technique [0002] Peanut is a well-known and commonly used food rich in fat, which is grown and widely used all over the world. It contains protein, fat, sugar, vitamins A, B2, B6, D, E, K, and various minerals such as calcium, phosphorus, iron, etc., contains 8 kinds of amino acids and unsaturated fatty acids needed by the human body, and contains lecithin , choline, carotene, crude fiber and other substances. Among them, the fat content is 44%-51%, the protein content is 24%-36%, and the sugar content is about 20%. It can be seen that peanuts are very rich in nutrients and functional components, and have various health functions such as promoting the development of human brain cells, enhancing memory, improving and protecting cardiovascular and cerebrovascular. [0003] Peanut oil is light yellow and transparent, with c...
