Description

Deacidification detoxification processing apparatus is used in cottonseed oil processing Technical Field The invention relates to the technical field of cotton seed oil chemical deacidification, in particular to a deacidification and detoxification treatment device for cotton seed oil processing. Background Cottonseed oil is an important edible vegetable oil but contains specific cyclopropene fatty acids such as sterculic acid and mallow acid which are biotoxic and interfere with the normal metabolism of the organism and must therefore be removed during its refining. At present, an alkali refining method is widely adopted in industry for deacidification and detoxification, and free fatty acid in grease reacts with added alkali liquor (usually sodium hydroxide solution) through a neutralization reaction to generate oil-insoluble fatty acid sodium, namely nigre. The patent of the invention with the publication number of CN120442318B discloses a processing device for removing cyclopropene fatty acid in cotton seed oil, and through deep analysis, the proposal has the problems that 1, in the screening stage, an upward moving screen is extremely easy to be stuck and blocked by flocculent or granular soapstock which is generated, and the screen moves upwards in liquid, so that the liquid and the soapstock form positive pressure on the screen, so that the soapstock particles are rapidly compacted in meshes, and the filtering capability of the soapstock is rapidly reduced. The fully blocked screen can impede the normal passage of liquid, but instead form unintended secondary pistons in subsequent upward movement, interfering with the preset liquid flow field, and possibly causing the springs pulling the slide plate to be in an abnormally stretched state for a long period of time. 2. The spring for pulling the sliding plate is stretched back and forth in alkaline and viscous medium for a long time, so that corrosion fatigue and elastic attenuation are easy to occur, and the restoring action of the sliding plate is failed. 3. The slide rod is directly exposed in the center of the flow channel, the continuous impact of high-speed liquid flow can cause fatigue or misoperation of the mechanism when the piston moves downwards, and the slide cylinder accommodating the mechanism is easy to remain soapstock impurities in the slide cylinder to cause mechanical clamping stagnation, so that the deacidification and detoxification treatment device for processing the cotton seed oil is provided to solve the problems.
