A method and system for controlling low-temperature pressing of peanuts

Abstract

An embodiment of the invention discloses a low-temperature peanut pressing control method. The method comprises steps as follows: a temperature threshold value T and a pressure threshold value P of a fifth gear area of an oil press are set; the actual temperature t and the actual pressure p of the fifth gear area of the oil press are acquired; the size between t and T and the size between p and P are judged; when t is larger than T, the difference of t and 5 DEG C is smaller than or equal to T, p is larger than P and the difference of p and 0.4 Mp is smaller than or equal to P, the output frequency of a miniature spiral conveyor for cake particles is reduced, the introduction amount of steam into a conditioning pot is reduced, and the input quantity of materials into the conditioning pot is increased; when t is smaller than T, the sum of t and 5 DEG C is larger than or equal to T, p is smaller than P and the sum of p and 0.4 Mp is larger than or equal to P, the output frequency of the miniature spiral conveyor of cake particles is improved, the introduction amount of steam into the conditioning pot is increased, and materials are stopped from being added to the conditioning pot; when t is equal to T and p is equal to P, the output frequency of the miniature spiral conveyor for the cake particles is kept unchanged, the introduction amount of steam into the conditioning pot and the material input quantity are unchanged; otherwise, the oil press is stopped from running. The invention further discloses a low-temperature peanut pressing control system for controlling peanut press equipment.

Description

technical field [0001] The invention relates to the technical field of low-temperature pressing of peanuts, in particular to a method and system for controlling low-temperature pressing of peanuts. Background technique [0002] Peanut is an important oil crop and economic crop in my country. The sown area of ​​peanuts in China accounts for 20% of the world's peanut sown area, but the total output accounts for more than 40% of the world's peanut production, and the peanut export volume accounts for more than 45% of the international peanut trade. Therefore, my country's peanuts occupy a pivotal position in the world's peanut production, trade and processing. Peanut oil is one of the more common peanut processed products, and it is a widely eaten vegetable oil. Because it can decompose cholesterol in the human body into bile acids and excrete them from the body, it can reduce the content of cholesterol in plasma and contains sterols. , wheat germ phenol, phospholipids, vitamin...

Problems solved by technology

After tempering treatment, the surface of peanut crumbs is smooth, the elasticity and plasticity increase, and the hardness decreases. When adding water and heating inappropriately, it is easy to appear in the oil press machine. Insufficient force, it is easy to form a smooth bore phenomenon, which makes it difficult for materials to be continuously fed and pressed, and continuous operation cannot be performed, which affects the progress of the pressing work.

[0004] In the prior art, in order to solve the above-mentioned smoothbore phenomenon, cake grains that increase friction are added to the tempered peanut grains. It is still unable to solve the above-mentioned smoothbore phenomenon
