Ceramic grinding disc for food grinding processing

Abstract

A ceramic grinding disc for food grinding processing solves the problems that for an existing grinding disc, foodstuff distribution is nonuniform, the diversion speed is low, discharging is difficult, feeding blocking is prone to be caused, and the grinding efficiency is low. The ceramic grinding disc is characterized in that the internally-concave conical surface of a fixed grinding disc body is provided with symmetrical step-shaped oblique teeth, and the internally-concave plane of a movable grinding disc body is provided with material guide grooves and trapezoid teeth; according to the movable grinding disc body, multiple trapezoid teeth which are independent and are mutually staggered form a grinding tooth array, and according to the fixed grinding disc body, multiple independent symmetrical step-shaped oblique teeth form the internally-concave conical grinding surface. The ceramic grinding disc for food grinding processing has the advantages that foodstuffs conduct dynamic collision with the movable grinding disc body and the fixed grinding disc body in an internally-concave conical grinding cavity between the movable grinding disc body and the fixed grinding disc body, the flowing velocity of the foodstuffs is increased under the synergistic action of extruding, breaking, shearing and grinding, secondary grinding is conducted through the two peripheral grinding surfaces of the movable grinding disc body and the fixed grinding disc body, the ground foodstuffs are filtered and flow out of grinding and screening gaps, the grinding efficiency and the grinding effect are improved, and the grinding disc is high in strength, good in wear-resisting property, long in service life and suitable for industrialized continuous production.

Description

technical field [0001] The invention belongs to the technical field of food processing machinery, in particular to a ceramic grinding disc used for food grinding. Background technique [0002] (1) The traditional tool for grinding food is a stone mill, which consists of two short cylindrical stones of the same size and Grinding disc The lower fan (static grinding disc) and the upper fan (moving grinding disc) are stacked on the grinding disc, and the contact surfaces of the two milling fans are chiseled with neatly arranged grinding teeth for grinding food. This kind of grinding structure using the upper grinding disc as a moving grinding disc and the lower grinding disc as a static grinding disc is still in use today. However, this traditional stone mill is provided with an eccentric feed inlet on the movable grinding disc, the food material is not evenly distributed, and there is intermittent empty grinding in the center of the grinding disc, so the grinding efficiency is...

Problems solved by technology

[0010] (1) To solve the technical problem of moderate strength and moderate wear resistance of the grinding disc, it not only makes use of the advantages of wear resistance of ceramics, but also overcomes the problems of high brittleness and poor impact resistance of ceramics, so as to meet the requirements of fineness greater than 100 mesh The purity of food during ultra-fine processing can also reduce the manufacturing cost of the grinding disc and reduce the unit volume weight of the grinding disc, so that when it is subjected to the centrifugal force of high-speed rotation, it reduces the bending moment generated by the motor shaft that drives it to rotate and torque to increase the service life of the product
