Nitrogen cabin for nitrogen-filled packaging of tea

Abstract

The invention discloses a nitrogen cabin for nitrogen-filled packaging of tea leaves. The cabin comprises a nitrogen-filled cabin body, wherein a conveyor belt is arranged in the nitrogen-filled cabin body, and a group of tea canister bases are fixedly arranged on the conveyor belt; a tea weighing and charging machine, a nitrogen charging device, a film sticking machine, a film sealing machine and a cap screwing machine are sequentially arranged above the conveyor belt; a nitrogen filling device comprises a cover cap, wherein a vacuumizing pipeline and a nitrogen filling needle tube are connected to the cover cap, a stop valve is arranged on the vacuumizing pipeline, a nitrogen charging injector is connected to the upper portion of the nitrogen filling needle tube, and the nitrogen filling injector comprises a metering cylinder with scale marks and an injection plug. One end of the injection plug is connected with a power device for driving the injection plug to move back and forth. The nitrogen-filled tea packaging quality can be improved, the nitrogen consumption is reduced, nitrogen leakage and waste are avoided, and the nitrogen cabin for nitrogen-filled packaging of tea can be widely applied to the field of nitrogen-filled tea packaging.

Description

technical field [0001] The invention relates to the field of tea processing equipment, in particular to a nitrogen chamber used for nitrogen-filled packaging of tea. Background technique [0002] At present, in terms of nitrogen-filling and fresh-keeping of tea in our country, nitrogen-filling packaging machines are generally used to directly carry out nitrogen-filling packaging in the workshop. Although this nitrogen-filled packaging method can also achieve a better nitrogen-filled fresh-keeping effect, it does have problems such as easy leakage of nitrogen gas, large amount of nitrogen gas, and high cost of nitrogen filling, especially the difficulty in controlling the amount of nitrogen filling and uneven nitrogen filling. It has affected the freshness quality of tea packaging. In addition, in the existing nitrogen filling production line, after the nitrogen filling is completed and before the tank is sealed, the tea and tea packaging are exposed to the air, which is eas...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a nitrogen chamber for nitrogen-filled packaging of tea, which solves the problems of easy leakage of nitrogen gas, unstable nitrogen filling amount, and easy contamination of the tank body when the existing tea is packed in cans.
