Tea leaves are easy to absorb moisture and odors, therefore we need to pay particularattention to its storage. The preservation temperature is between 0℃ ~ + 8℃ and is free to set.The relative humidity is below 65%, completely solve the problem that tea is highly perishablewhen leaves at high temperatures and high humidity surroundings. The tea cold storage is used to cool down and reduce the humidity, thereby reaching the purpose of keeping green tea fresh. The freezing temperature is controlled between ~18 ~ -10, which can prolong the storage time to more than half a year.
The preservation temperature is controlled between 0 ℃ ~ + 8 ℃. The temperature inside can be set freely. The relative humidity keeps at 65% or less. The problem that tea leaves easily turns yellow and bad enzymatically under high temperature and high humidity is solved completely. The tea leaves cold room reduces the temperature and humidity to achieve the purpose of keeping the leaves fresh and green. .
The deterioration caused by microorganism limited by temperature, moisture, oxygen and other factors, while the odor pollution is related to the storage conditions. To prevent deterioration, the light, temperature, moisture and oxygen light, packaging materials must be controlled. The packaging materials should be light-shielding, such as metal cans, aluminum foil laminated bags. Vacuum, nitrogen filling or deoxidizer can be used to remove the oxygen. Because tea leaves have quite strong hygroscopicity, the relative humidity in cold room is better controlled at below 65%. The moisture content during storage should be maintained at less 5%. The storage temperature should be controlled in the range of 10℃ ~ -18 ℃. Then the storage period can extend to more than 6 months.
The Main Factors of Tea Leaves Deterioration :
There are three kinds of surface material for chosen, stainless steel, aluminium plate and color steel. The thickness of panel are 50 mm, 100 mm, 120 mm, 150 mm, 200 mm. You may choose the surface panel and thickness based on your requirements.
This unit is installed on the wall of the cold room. We provide wall panel with window for the installation. Thus, it is easy to install. There is no need for welding.
The air cooler is seperated from the other parts of the unit. The connection is using copper connector, like the one in air conditioner. So the installation is as easy as installing an air conditioner.
Good quality pressure gauge is used for pressure monitoring. And pressure protector is used to avoid pressure damage.
