Description

Technical Field

[0001] The utility model relates to the technical field of flour grinding equipment, and more specifically, to a flour grinding device. Background Art

[0002] The development history of stone mill flour machinery can be traced back to ancient times. After hundreds of years of development, it has now become a production equipment that represents green, healthy, environmentally friendly and efficient. The reason why stone mill flour machinery is widely used is that it has many advantages. First of all, it is made of natural stone, which avoids the metal pollution of food caused by the use of metal molds. Secondly, the production process of stone mill flour machinery does not add any chemicals, which fully meets the requirements of green food production. In addition, due to the low-speed operation and low-temperature processing of the stone mill, the original nutrients of the food can be retained, especially for some easily oxidized nutrients, which can play a good protective role.

[0003] Traditional stone mills usually consist of two round stones, one of which is fixed and the other can rotate on it. In this way, grain particles can be continuously ground into powder.

[0004] However, it still has some disadvantages in actual use. The powder trough in the existing stone mill is usually open. This open setting is mainly convenient for operators to use a brush to clean the flour from the powder trough into the container. However, this open setting, on the one hand, is prone to cause flour dust to fly, and on the other hand, the flying dust from the outside is also easy to enter the flour, which also makes it difficult to pick it out later.
