According to the difference in the possession and preservation of the target and Tiecao Tiecha, the methods of preservation and storage of Tieba are mainly divided into two categories: professional and family. The main preservation is professional: tea merchants save their teas, and the family mainly uses a small amount of Tiecha. The preservation.
Professional preservation method:
The first method is lime preservation. Lime blocks are packed in bags made of white cloth. Weekly beaten iron tea into white cotton paper bag, coat kraft paper bag, and then move pictures of small pottery jars to wash and dry, lay white paper, place the week's hitting tea bag in small pottery jars, and insert one or two lime bags in the middle. . Several layers of grass are used to seal the mouth of the altar and finally compacted with bricks or planks to reduce the amount of air exchange. Afterwards, the preservation should be checked frequently and the lime should be promptly replaced after the deliquescence.
The second is carbon storage. The method of operation is basically the same as the lime block preservation method. The material used is only charcoal that is extinguished by combustion. The tea utensils can be replaced by a jar or small tin bucket. The capacity of charcoal bags and hot tea bags can be increased or decreased depending on the size of the container.
The third is the week to fight iron tea refrigeration method. The tea leaves are dried with moisture, with a moisture content of between 3-5% and no more than 6%. The week-long iron tea tea was packed into aluminum-coated composite bags, heat-sealed, and the air in the bags was extracted with a breathing aspirator. At the same time, nitrogen was flushed, the sealing tape was sealed, placed in a tea box, and then stored in a cryogenic refrigerator. This method is the best method of tea preservation under the current state of science and technology. Save a large amount of time for a long time.
