Tea cold storage is used to remain freshness for tea mainly. It is composed of thermal insulation warehouse, cold storage door, automatic temperature control system, refrigeratory compressor cooling system, air refrigerating machine. Its functions are automatic temperature control and dehumidification. So temperature can be controlled between 0°C~8°C and set freely to control humidity below 65%. Then to solve the problem that tea spoil in the case of high temperature and humidity. Tea cold storage lower the temperature and humidity to keep tea fresh and green.
Tea cold storage refrigerate tea in low temperature to extend the fresh time. Small tea storage adopt new refrigeration technology to remain the appearance and taste to enhance the economic value of tea. Small tea storage is mainly combined type. It has smaller volume. Then removal and installation are very convenient. It applies to tea company storing up top grade tea because of great thermal insulation performance and low cost.
Tea cold storage structure feature:
1,Thermal insulation panel: using double color steel polystyrence insulation panel or polyurethance thermal insulation panel. Its features are dampproof , anti-corrosion, clean, non-toxic, no rust. 100mm thick double color steel pupanel ensures heat insulation performance.
2,Refrigeratory compressor unit: using totally enclosed compressor in international famous brand. Its features are low energy consumption , small noise, low failure rate and long service life. Air cooling type cooling systems save energy and space effectively. Installation and maintenance are simple and convenient. Evaporator adopts international famous air refrigerating machine and occupies less space.
Automatic dehumidification: Air refrigerating machine also remove moisture in the air when refrigerating. Then humidity below 60% in it ensures dryness of tea and provide low temperature and drying environment for tea.Temperature-control system: Microcomputer automatic control system can freely set temperature to control precisely. There is no need to care for the system. So this saves human resource.
Common sense of cold storage in tea:
1,Green tea is best placed in the cold storage temperature 5°C~8°C. The temperature is as high as possible while it is hotter to reduce the temperature difference between tea and air. The measure saves electricity consumption and extends service life. Due to the large difference in humidity inside and outside the cold storage, when taking the tea from the storage, the tea bag should be moved out firstly, then unpack after the tea bag closing to room temperature. If opening tea bag immediately, the steam in the air touches the low temperature tea, it deliquesces droplet, then makes tea damp.
2,The whole process from picking to selling out is in the cold storage in some foreign countries. This ensures the quality of tea. However, there is not such standard in our country.
3,Air cooler is used as evaporator. Its purpose is to remove moisture. Constant cycle of indoor air flow in order to make air cooler operate. If the cold storage is filled with tea, air cooler won't refrigerate with tea blocking the wind tunnel.
