Squeezing and grinding machine for food materials

Abstract

The invention discloses a squeezing and grinding machine for food materials. The squeezing and grinding machine comprises a feeding mechanism, a grinding mechanism, a driving mechanism, a filter screen, a discharging mechanism and a shell. The feeding mechanism comprises an accommodating hopper, and the accommodating hopper is provided with a feeding channel; the grinding mechanism comprises an upright spindle-shaped screw and an abrasive disk, the abrasive disk sleeves the screw, the screw and the abrasive disk can fittingly rotate in reverse directions, and at least one layer of knife rings is arranged in the rotary abrasive disk. The squeezing and grinding machine has the advantages that strip-shaped cutting knives are arranged in the rotary abrasive disk, particle withdrawing grooves are formed in the rotary abrasive disk, the strip-shaped cutting knives are matched with the rotary screw, shearing-shaped intersections are formed between spiral of the screw and the oblique cutting knives of the knife rings when the screw and the abrasive disk move relatively, and the food materials can be shorn and smashed and can be cut and smashed by each layer of cutting knives and knife grooves of the rotary abrasive disk, a body of the screw and convex strips of the screw; the particle withdrawing grooves for driving and compressing the food materials to reversely convey and feed the food materials from bottom to top are formed by the oblique knife grooves of the reversely rotary abrasive disk.

Description

technical field [0001] The invention relates to a food pressing and grinding machine. Background technique [0002] Among the existing household food juice extractors and mills, one class continues the traditional food processing method and is suitable for miniaturization, such as: mixers, disc grinders, small steel mills, and coffee grinders. The other type is new concept products that appear 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 methods ado...

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

[0009] 5. Existing mills are mainly used to extract juices from fruits and vegetables into beverages, which are insufficient in function and cannot be used for milling whole grains, such as the mills disclosed in Chinese patents 201310378880.1 and 201210303377.5
