How to select the material and processing technology of coffee filter

With the continuous improvement of people's living standards, a cup of strong coffee for breakfast has gradually become the ideal breakfast for most white-collar workers. Therefore, coffee machines are constantly derived from life. China's home appliance industry started late, but this does not affect China entrepreneurs' keen innovation and continuous R&D ability, and coffee machines have gradually become miniaturized. Let's briefly describe the basic structure and processing technology of coffee machines.

The basic structure of coffee machine is mainly composed of water tank, water pump, water heater, coffee powder bag, filter, coffee cup, etc. The water tank is the storage water source, the water pump pumps water from the water tank, the water heater is used to heat water, the coffee powder bag is used to store coffee powder, the filter is used to filter coffee, and the coffee cup receives coffee.

The most important thing is the filter disc in the coffee machine. The main reason why we should emphasize it is that there are many coffee filters on the market at present, which also determine the degree of coffee filtration. The precision of coffee filters in high-end coffee machines requires ultra-thin and miniaturization. The traditional coffee machine filter is made by punching holes. Later, with the improvement of technical level and the development of household appliances, miniaturization has gradually become a trend, so the etching filter has gradually replaced the traditional extensive processing method. Etching filter screen has gradually become a trend. The conventional processing material of coffee filter screen is mainly stainless steel. Because stainless steel has the characteristics of corrosion resistance and alkali resistance, it is important not to rust, and it is easy to disassemble and clean under reasonable design. By etching coffee filter screen, the characteristics of products can be well displayed. The etched coffee filter has a smooth surface and no burr on the side, especially the aperture with a tolerance range of 0.05MM can be accepted in high precision, and the etching thickness can reach 0.01MM-2MM, which can determine the thickness and aperture size of the coffee filter according to the design of the coffee machine in the process of processing the coffee filter, making the integrity of the coffee machine more perfect and exquisite.
