Problems solved by technology

However, in the adsorption process of activated carbon, in order to improve the removal efficiency of aflatoxin in peanut oil, the peanut oil needs to be stirred, which inevitably collides with the activated carbon to produce fine particles, and the activated carbon adsorbent itself will carry more fine solid particles. These fine solid particles are difficult to remove by simple filtration, which affects the quality of peanut oil products

Abstract

The invention discloses equipment and method for removing aflatoxin in peanut oil. A rotating shaft drives stirring blades and a centrifugal drum to rotate, acting forces in the same direction are simultaneously applied to the peanut oil by plate bodies on the inner walls of the centrifugal drum and the stirring blades, so that the peanut oil rotates, and fine particles in the peanut oil can outwards move under a centrifugal action, can be intercepted by the plate bodies on the inner walls of the centrifugal drum, can rapidly move downwards along a flowing channel located between the plate bodies and can be deposited between a lower end socket of the centrifugal drum and a lower end socket of a separation tank through a through groove in the lower end socket of the centrifugal drum. The fine solid particles gathered between the plate bodies are accelerated to move downwards under the action of a force of the peanut oil, and furthermore, the rapid separation of the peanut oil and the solid particles is realized.

Description

technical field [0001] The invention belongs to the technical field of grain and oil quality safety, and in particular relates to a device and method for removing aflatoxin in peanut oil. Background technique [0002] Peanut oil is light yellow and transparent, clear in color and fragrant, and is a kind of edible oil that is relatively easy to digest. Which is rich in nutrients, including sterols, wheat germ phenol, phospholipids, vitamin E, choline and other substances beneficial to the human body. Regular consumption of peanut oil can prevent skin wrinkling and aging, protect blood vessel walls, prevent thrombosis, and help prevent arteriosclerosis and coronary heart disease. Choline in peanut oil can also improve the memory of the human brain and delay brain function decline. However, the pollution of peanut oil by aflatoxin is a worldwide problem. Aflatoxin is a secondary metabolite produced by Aspergillus flavus and Aspergillus parasiticus, which can cause acute and ch...
