1. What is capsule coffee?
Capsule coffee is grinded with coffee beans into coffee powder, and then loaded into aluminum capsules, which eliminates the problems of ordinary coffee beans or coffee powder after contacting the air, and oxidation and other problems.
The outer shell of the capsule uses PBT materials, which has the characteristics of high temperature resistance, hot water, and various oil erosion. Widely used for the manufacture of coffee utensils and daily necessities. At the rear of the capsule, there are 3 to 6 holes, and the water flows entered by rotation, which is more full of internal coffee.
2. How to achieve hand -coffee coffee flavor of capsule machine
In the field of food processing technology, the method of preparing handmade coffee, which includes the heating stage, the initial water injection stage, the stuffing steaming stage, and the extraction stage, which mainly depends on the increase of the stuffing steaming stage. Therefore, the coffee prepared through this method is closer to hand. The taste of coffee. Inject hot water into the capsule of coffee powder and stop the water supply for a period of time, so that the hot water and coffee powder are fully exposed. The coffee powder is heated and expands the carbon dioxide. Powder forms a uniform filter layer, which provides space required for hot water to improve the quality of coffee extracted during the extraction phase. The volume of coffee powder is not greater than 80%of the capsule accumulation, which reserves space for coffee powder to expand and forms a gap to prevent coffee powder from uneven gap between coffee powder in the capsule. quality.
3. How to accurately control the water flow and water temperature of the capsule coffee machine?
Water temperature is an important factor affecting the taste for coffee. Nowadays, various coffee machines are emerging, but most of the common coffee machines use thyristor or relay as temperature switching devices. The cost -controlled electronics cost is high and the heat dissipation requirements are high; the relay has switch life and switching time, so it is not suitable for frequent switches for temperature control. At the same time, the existing water flow speed control coffee machine on the market has the shortcomings of low accuracy, poor stability, and long response time, which is not conducive to ensuring the taste of coffee. One ,, coffee machine water temperature control, including heating modules, temperature collection modules, water flow speed control modules, and MCU main control modules; Adapt to the accuracy of adjusting water flow to 5%, and the heating module achieves real -time precise water temperature.
s1. Start the heating switch to preheat, and obtain the temperature of the heating parts in real time;
s2. When the temperature of the heating part reaches the temperature threshold of the preset component, start the water pump and collect water temperature in real time to get real -time water temperature;
S3. When the real -time water temperature reaches the preset water temperature threshold, the water temperature is regulated segmented according to the real -time water temperature and target water mild PID algorithm.
Angel water pump can control water flow at a precision of ±5% for different flow range.
