Description

Manual stone mill

Technical Field

The application relates to the technical field of food processing machinery, in particular to a manual stone mill.

Background

The stone mill is a machine for processing food materials such as rice, wheat, beans and the like into powder and slurry, and generally consists of a movable millstone and a fixed millstone which are arranged up and down, wherein the bottom surface of the movable millstone facing the fixed millstone and the top surface of the fixed millstone facing the movable millstone are both provided with texture structures for grinding, after the food materials enter a grinding gap of the movable millstone and the fixed millstone, the movable millstone rotates relative to the fixed millstone, the food materials can be ground into powder or slurry by the texture structures, and the powder or slurry is pushed out along with the rotation of the movable millstone.

The stone mill can grind at a low speed, process at a low temperature and grind uniformly, and does not destroy nutrient substances in food materials, so that the stone mill grinding food materials fully maintain nutrient components in the food materials, retain the original taste and flavor of food, and various foods manufactured by the stone mill process are flexible in taste, aromatic and rich, have higher nutritional value, and are natural green health foods, so that the stone mill is deeply favored by people.
