Rotary vane vacuum pump used in the tea store _

tea maker has been looking for can help to store a lot of tea. Rotary vane vacuum water pump application in the tea. Because tea like to smell, so more afraid of moisture, heat and light, need to be dry, clean, dark, low temperature, low oxygen; Avoid to contact a peculiar smell, high water content, light, high temperature environment, exposure to space. According to these requirements, the tea must be drawn in front of the store.

tea has strong moisture absorption and odor absorption, easy to absorb moisture in the air and smell. If a little inappropriate storage method, flavor will disappear in a short period of time, and the higher the price of high tea, save, the more difficult. Usually, the aroma of tea preservation after a period of time, taste and color changes. The original new tea party disappear, taste will gradually disappear. Therefore, to master the tea storage method can ensure the quality of the tea in life is indispensable.

tea can absorb the moisture and odor absorption. Therefore, we should pay special attention to the proper storage and packaging. In addition to beautiful, convenient, health requirements and product protection, must also prevent moisture and odor during storage, to ensure the quality of the tea. The main factors of tea metamorphic is: light. Second, the temperature. The third is the water content of tea. The fourth is atmospheric humidity. Five, oxygen. Six, microorganisms. Seven, odour pollution. Caused by microbial metamorphism, such as temperature, humidity, and oxygen factors such as limit, and odor pollution associated with the storage environment. So we must control the light, temperature, humidity, and oxygen in order to prevent the tea metamorphism. Packaging material must be shadow, such as metal cans, aluminum foil laminated bags, etc. Can use rotary vane vacuum pumps or nitrogen filling packing removal of oxygen. You can use the deoxidizer. There are two types of storage methods: under normal temperature and low temperature storage, depending on the temperature of the storage space. Due to the moisture absorption of the tea is very strong, whatever storage methods, storage space of the relative humidity should be controlled under 50%, and the water content of tea during storage should be kept below 5%.

according to the degradation of the characteristics of tea and tea, tea storage and storage is dry (theoretically Water content less than 6%, the optimum 3% 4%) , cold storage, It is best to zero degrees Celsius) Is ideal for anaerobic ( The vacuum or nitrogen gas) And light protection. But, because of various objective conditions, these conditions are often impossible. Therefore, in the concrete operating process, can grasp the tea dry necessary requirement, can delay the aging process of tea according to the existing conditions, and take other measures.

rotary vane vacuum pump application in the tea store does not apply to all tea, need to be used according to different tea varieties. With the continuous development of society, people pay more and more attention to their health. Food is not in order to fill the stomach. People are more concerned about their health functions. From health to health care, food has become inevitable. As the most advanced health products, tea should ensure that its quality is not affected in a certain time or minimized, effectively extend the shelf life of tea, can make consumers buy has good color, fragrance, taste, shape of the tea products. Tea storage is based on the basic original packaging to ensure that the tea quality of tea process.
