Twin-screw oil press with cooling device

Abstract

The invention relates to a screw oil press, in particular to a twin-screw oil press with a cooling device. The twin-screw oil press comprises a rack, wherein a hollow pressing shaft is arranged above the rack; the pressing shaft is fixedly provided with a plurality of spiral blades; a pressing row is sleeved out of the blades; the pressing row consists of two half-cylinders; one end of the pressing shaft is provided with a transmission mechanism; a pressing row cavity is formed between the pressing row and the blades; one end of the pressing row cavity is communicated with a material inlet arranged above the upper side; the other end of the pressing row cavity is provided with a cake outlet adjusting mechanism; the material inlet is provided with a spiral feeding mechanism; an oil collection tank is arranged on the middle part of the rack and below the pressing row; the side of the rack corresponding to the cake outlet adjusting mechanism is provided with a cake collection tank; and the oil press further comprises a pressing shaft cooling device and a pressing row cooling device. With the adoption of the oil press, the temperature in a peanut oil pressing process is controlled effectively, and the condition that the cake temperature in the peanut oil pressing process is not higher than 60 DEG C is ensured, so that the condition that the modification of peanut protein and the loss of micro beneficial components is avoided, the quality of cold-press peanut oil is guaranteed; besides, the oil yield is high and the power consumption is low, thereby the twin-screw oil press is beneficial to development and promotion.

Description

technical field [0001] The invention relates to a screw oil press, in particular to a double-screw oil press with a cooling device. Background technique [0002] Peanuts are rich in fat and protein, and also contain various amino acids, vitamins and other nutrients needed by the human body. my country is rich in peanut resources, and its output ranks first in the world, with an annual output of 17 million tons of peanuts. Peanut is also one of the six major oil crops in my country. Peanut oil contains linoleic acid, linolenic acid, arachidonic acid and other unsaturated fatty acids necessary for the human body. It plays an important role in regulating human body functions, promoting human growth and development, and preventing human diseases. Modern medicine believes that the linoleic acid, arachidonic acid and vitamin E contained in peanut oil have good preventive and therapeutic effects on coronary heart disease and hypertension, and can lower cholesterol, which has a si...

Problems solved by technology

[0003] Although some existing companies use cold pressing in the production of peanut oil, they are not actually cold pressing in the true sense, ignoring the heat generated by peanut cracking, extrusion deformation, friction and other factors during the rolling process. Cause temperature rise, resulting in denaturation of peanut protein and loss of trace beneficial components
