Double-spiral grinding mechanism

Abstract

The invention discloses a double-spiral grinding mechanism. The double-spiral grinding mechanism comprises a spinning-cone-shaped screw rod vertically extruding food materials to move downwards, and a grinding disc arranged outside the screw rod in a sleeving manner and cooperated with the screw rod to oppositely rotate, wherein at least one layer of knife ring is arranged in the rotating grinding disc, the knife ring comprises a plurality of strip-shaped cutting knives intersected with convex bars of the screw rod, and an inclined knife groove is arranged or formed between each two cutting knives, and is shallow in bottom and deep in top; each layer of cutting knife and knife groove of the rotating grinding disc, a screw rod body and the convex bars of the screw rod form cutting crushing for the food materials; and the inclined knife grooves of the oppositely-rotating grinding disc form grain return grooves driving and pressing the food materials to be oppositely conveyed and fed from bottom to top. The double-spiral grinding mechanism disclosed by the invention weakens extrusion of the screw rod and the grinding disc for a cutting cavity and then eliminates an effect of an extrusion chamber of the cutting cavity, and overcomes the phenomena of congestion and blockage of grains due to continuous pushing of a main spiral in the prior art. The problem of high heat due to friction increase during cutting is solved while resistance in cutting is reduced, and a machining cutting cavity without extrusion and heat is realized.

Description

technical field [0001] The invention relates to a double spiral milling mechanism. Background technique [0002] Among the existing household food mills, one is the continuation of the traditional food processing method, which is suitable for miniaturization, such as: mixer, disc grinder, small steel mill, coffee grinder, etc., and the other is The category is a new concept product that has emerged under the higher requirements for food processing technology with the continuous improvement of people's lives, such as: high-speed wall breaking machine, powder making machine, centrifugal juicer, etc. This type of machine comes from the new attempt and application of non-food material crushing technology in the field of food processing. Under the guidance of the fast and refined path, the destructive effect on the nutritional components and original structure of the ingredients is much greater than that of the former traditional processing machines. It explains that the method...

Problems solved by technology

[0006] 2. The uneven particles produced by processing affect the original elasticity and toughness of the ingredients in the subsequent cooking, fermentation, and soaking. Especially in the cooking of coffee, the permeability becomes poor, and the raw juice is lost due to uneven raw and cooked. The original taste reduces the economic value of the product and the dust generated during the processing destroys the original structure of the ingredients, and loses a lot of nutrients and original flavor. When processing fresh fruits and vegetables, it may even change color and taste, which is obvious. In the effect of excessive crushing of the high-speed crushing method of the wall breaker and the powder machine

It shows that whether high speed or low speed is used, as long as the process is gradually processed from coarse to fine, repeated cutting of particles cannot be avoided, resulting in overprocessing of food materials. The above problems are caused by a structural defect and the occurrence of Disadvantages in processing methods
