Description

Technical Field

[0001] This utility model specifically relates to an easy-to-disassemble hand-cranked coffee grinder, belonging to the field of coffee grinder technology. Background Technology

[0002] Coffee is a beverage made from roasted and ground coffee beans. Along with tea and cocoa, it is considered one of the world's three major beverages. Moderate coffee consumption can reduce the risk of diabetes. Coffee also has anti-inflammatory properties, helps protect the heart, and improves spatial awareness. Coffee beans, as the main raw material, have their type, processing method, and roasting degree all affecting the final coffee flavor. When brewing coffee, the beans need to be ground into powder before brewing. The degree of grinding significantly impacts the coffee's flavor. Coffee grinders are the key equipment used for grinding coffee beans. From the perspective of their operation, coffee grinders can be divided into manual and electric types. Those who pursue a high quality of life mostly use manual grinders to enhance the enjoyment of drinking coffee. However, existing hand-cranked grinders are inconvenient to disassemble, making it difficult for users to clean the internal structure, thus affecting the flavor of the subsequent coffee. In view of this, this utility model is proposed. Utility Model Content
