Improved stone mill

Abstract

The invention relates to the field of processing of agricultural products, in particular to an improved stone mill. An upper mill body and an upper abrasive disc of the stone mill are fixedly connected to a bracket; a feeding hole passes through the upper mill body and the upper abrasive disc to reach a milling chamber between the upper abrasive disc and a lower abrasive disc; the lower end of a pressure valve with pressure capable of being regulated through a supporting spring is fixedly connected to the upper surface of the upper abrasive disc; the upper end of the pressure valve is fixedly connected to the upper part of the bracket; pressure applied to the upper abrasive disc is regulated by rotating a pressure valve rotary plate; the upper mill body is a metal box body; during operation, a cooling medium is injected into the metal box body; a delivering pipe with a valve and a gas exhaust pipe are arranged on the metal box body; the cooling medium enter and exit from the upper mill body through the delivering pipe; and a lower mill body is fixedly connected to the lower abrasive disc, and can be driven to rotate by a transmission shaft driven by a motor. According to the improved stone mill, a cooling device stored with the cooling medium is additionally arranged, so that temperature in a material processing process is controlled within a certain range, and therefore, the nutrition ingredients are protected, and natural flavor is guaranteed.

Description

technical field [0001] The invention relates to the field of agricultural product processing, in particular to an improved stone mill. Background technique [0002] A stone mill is an agricultural product processing machine used to process rice, wheat, beans and other grains into powder and pulp. It consists of two short cylindrical stones of the same size and a grinding disc. Generally, it is set on a platform made of stone or adobe, and the stone or wooden grinding disc used for flour connection is stacked with the lower fan of the fixed disc and the upper fan of the rotating disc. The contact surfaces of the two mills are chiseled with neatly arranged grinding teeth for grinding grain. There are 1-2 grinding eyes on the upper fan for leaking grain. There is a grinding navel between the two mills to prevent the upper fan from falling off the lower fan when it is turning. The stone mill has a large mill with a diameter of more than three feet and six inches, which needs ...

Problems solved by technology

This utility model further solves the bulky problem of the electric stone mill. It is light in weight, small in size, and integrated with grinding and cleaning, but it cannot meet the low temperature requirements of traditional stone mills.
