The reason why the temperature of the ice machine can not fall is introduced:
1. Check if the temperature of your own adjustment is correct. If the temperature is not low, the temperature will not fall automatically. It may be the cause of the ambient temperature. If it is summer, suddenly adjust the attitude of the temperature, then it may not cool down at once, and a process is needed.
2. The throttle valve is improperly adjusted or blocked, and the refrigerant flow rate is too large or too small. If the throttle valve is improperly conditioned or blocked, it will directly affect the flow of refrigerant into the transpiration unit. When the opening degree of the throttle valve is too large, the refrigerant flow rate is too large, the transpiration pressure and the transpiration temperature also increase, and the warehouse temperature reduction speed will be slowed down.
3. The surface of the ice machine transpiration machine is too thick or excessively dusty, and the heat transfer effect is reduced. Another important reason for the slower temperature reduction in the tea shop ice machine is that the transpiration heat transfer power is low, which is mainly due to the excessive thickness or excessive dust on the outer surface of the transpiration machine.
4, the compressor power is low, the cooling capacity can not be satisfied with the warehouse load demand. Because the inferior compressor works for a long time, the sealing function will be reduced accordingly, and the compressor's gas transmission coefficient will also be reduced, and the cooling capacity will be reduced.
5. There is more air or frozen oil in the transpiration machine, and the heat transfer effect is reduced. Once the inner and outer parts of the transpiration heat transfer tube are attached with more refrigeration oil, the heat transfer coefficient will be reduced. Similarly, if there is more air in the heat transfer tube, the heat transfer area of ​​the transpiration machine is reduced, and the heat transfer is reduced. The power will also be significantly reduced, and the warehouse temperature will slow down.

Herbal tea is a health drink made from flower buds, petals or tender leaves of flowers and plants after harvesting, drying and processing. There are many kinds of herbal tea with different characteristics. Therefore, it is necessary to make clear the pharmacological and pharmacodynamic characteristics of different kinds of herbal tea when drinking, so as to give full play to the health care function of herbal tea.
The main varieties of herbal tea are chrysanthemum, rose, honeysuckle and so on.
How to brew: Herbal tea is usually brewed in a glass, China cup or pot with a lid and left for 2-5 minutes to release its active ingredients and distinctive floral aroma. But it is not appropriate to drink with zisha pot. Herbal tea belongs to non-fermentation tea, and it is mainly made of young and pollution-free flower buds and petals. The water temperature should not be too high when brewing, and the water temperature should be 80-90℃. Thermos cups are not suitable for brewing herbal tea, because under the condition of high temperature and constant temperature, various vitamins and aromatic substances contained in herbal tea will quickly be destroyed and reduced, and the tea will become dark in color and astringent in taste. In addition, in the process of brewing, the pot and cup should be sealed to reduce the loss of fragrance as far as possible.
Drinking skills: herbal tea is suitable for drinking, should not add milk, no or little sugar, can add a small amount of honey, to maintain the natural flavor.
Storage method: Herbal tea must be properly stored after purchase because it is rich in nutrition, fragrant and easy to be eaten by insects or damp. First of all, sealed packaging to prevent fragrance; Secondly, it should be placed in a cool and dry place to avoid direct sunlight and prevent deterioration and discoloration of herbal tea due to light, moisture and temperature. If the quantity of herbal tea is small, it should also be stored in a freezer bag and used up as soon as possible. The shelf life of herbal tea is generally 2 years, and the freshness period is 1 year. High temperature can also make the deterioration of tea materials, so usually stored in a cool place, but there is no need to put it in the refrigerator, otherwise, it is often easy to condense moisture caused by temperature difference when taking.
