Tea packing method

Abstract

The invention discloses a tea packing method. Existing tea packing methods are prone to leading to tea flavor loss and secondary seal difficulty. The tea packing method comprises putting finished tea into small packing bags, wherein the small packing bags are packed through zippers and are aluminized; inflating the small packing bags with inert gas at 6-8 atmospheres; putting the small packing bags into large tea packing bags, and vacuumizing and sealing up the large tea packing bags; placing the large tea packing bags and quick lime packed in mesh bags into paper cans; and packing the paper cans with plastic bags in a seal mode. The tea packing method is low in cost, and packed tea is good in solarization resistance, long in storage time and easy to seal up after being unpacked.

Description

technical field [0001] The invention belongs to the field of packaging, and in particular relates to a tea packaging method. Background technique [0002] Existing tea leaves are directly packaged in plastic after frying in the tea producing area. After a period of storage in such packages, the tea leaves will gradually turn yellow and oxidize due to the action of moisture and oxygen, resulting in a decrease in freshness. my country's patent In the application, it is useful to inject nitrogen gas to increase the fresh-keeping period of tea leaves, such as patent No. 91103805.1, which has high requirements for packaging and high cost, and is suitable for large-capacity packaging. In addition, it is easy to be heated during the transportation and sale of the product, which causes the tea to lose its fragrance or even deteriorate; and wherein the plastic bag is generally made by melting and bonding the plastic, and it is difficult to seal after opening the package.
