Description

Efficient household coffee bean two-stage manual grinding machine

Technical Field

The invention relates to the technical field of coffee grinding, in particular to a high-efficiency household coffee bean double-stage manual grinding machine.

Background

Coffee is a beverage made from roasted coffee beans, is a main beverage popular in the world together with cocoa and tea, and is one of three major beverages in the world, and the coffee beans refer to kernels in coffee tree fruits, and are roasted by a proper method, so that the coffee beans have different degrees of sweetness, acidity, mellowness or cleanliness in taste.

However, after the roasted coffee beans are purchased home, in order to make the coffee more easily brewed, the coffee needs to be ground into powder, so a manual grinder is provided in a household kitchen, while the conventional grinder grinds the roasted coffee beans through an internal grinding roller, and since the surface of the roasted coffee beans is smooth and the hardness of the roasted coffee beans is increased, the coffee beans are easy to roll between the grinding roller and the inner wall during the grinding process, so the grinding efficiency is reduced, and a large amount of oily substances are contained in the roasted coffee beans, and the roasted coffee beans are easy to adhere to an internal grinding mechanism after grinding, so that the roasted coffee beans are inconvenient to fall off and collect, and the conventional manual grinder cannot adjust the grinding thickness, so the grinding effect and the practicability of the grinder are reduced.

In order to solve the above problems, the inventor provides an efficient household coffee bean two-stage manual grinder, which can perform primary grinding and secondary grinding on coffee beans, so that the coffee beans are prevented from rolling at a grinding roller, the grinding efficiency is improved, the grinding thickness degree can be adjusted, the grinding effect and the practicability of a grinding device are improved, coffee powder can better fall downwards, and the collection is convenient.
