Embodiment 1

[0046] The present embodiment is a green tea packaging production line, comprising the following steps:

[0047] (1) Feeding: Put the green tea into the hopper of the Z elevator, and lift the green tea to the top of the 14-head combination scale through the lifting action of the Z elevator for feeding;

[0048] (2) Fully automatic weighing: the green tea put into the 14-head combination scale is transported to the weighing hopper for quantitative packaging of 14 parts, and then falls in sequence, and falls into the tinplate tank that is transported from the bottle unscrambler to the material receiving machine through the conveyor belt;

[0049] The weighing bucket is a special weighing bucket for green tea, which is suitable for weighing and quantifying various green teas.

[0050] (3) Nitrogen-filling and sealing: tinplate cans filled with green tea are sent to the nitrogen-filling and sealing machine sequentially by the conveyor belt, and then sent out of the nitrogen-fillin...

Embodiment 2

[0060] The present embodiment is a black tea packaging production line, comprising the following steps:

[0061] (1) Feeding: Put the black tea into the hopper of the Z elevator, and lift the black tea to the top of the 14-head combination scale through the lifting action of the Z elevator for feeding;

[0062] (2) Fully automatic weighing: the black tea put into the 14-head combination scale is transported to the weighing hopper for quantitative packaging of 14 parts, and then falls in sequence, and falls into the tinplate tank that is transported to the material receiving machine by the bottle unscrambler through the conveyor belt;

[0063] The weighing bucket is a special weighing bucket for black tea, which is suitable for weighing and quantifying various black teas.

[0064] (3) Nitrogen-filling and sealing: tinplate cans filled with black tea are sent to the nitrogen-filling and sealing machine sequentially by the conveyor belt, and then sent out of the nitrogen-filling ...

Embodiment 3

[0073] This embodiment is a herbal tea packaging production line, including the following steps:

[0074] (1) Feeding: Put the herbal tea raw materials into the hopper of the Z elevator, and lift the black tea to the top of the 14-head combination scale through the lifting action of the Z elevator for feeding;

[0075] (2) Fully automatic weighing: the herbal tea raw materials put into the 14-head combination scale are transported to the weighing hopper for quantitative packaging of 14 parts, and then fall in sequence, and fall into the tinplate cans that are transported to the material receiving machine by the bottle unscrambler through the conveyor belt middle;

[0076] The weighing bucket is a special weighing bucket for herbal tea raw materials, which is suitable for weighing and quantifying various herbal teas.

[0077] (3) Nitrogen-filling and sealing: tinplate cans filled with herbal tea are sent to the nitrogen-filling and sealing machine in turn by the conveyor belt,...

Abstract

The invention discloses a high-efficiency, environment-friendly tea or herbal tea nitrogen-filled fresh-keeping packaging method and its production process. The packaging tank filling method is adopted, and other soft packaging materials are omitted. The packaging tank is a tinplate can, which includes a tank body , the upper port of the tank body is provided with an inner cover and an outer cover, the inner cover is an aluminum foil inner cover, and the outer cover is a plastic cover, and the tank is directly sealed by the aluminum foil inner cover after filling the tank with nitrogen The upper port of the body is then encapsulated by a plastic cover. The tinplate cans used in the present invention are used for packaging. During the filling process of the tank body, the nitrogen gas technology is injected twice. Nitrogen-filled preservation can better maintain the taste and flavor of the product, and extend the shelf life for at least 3 months. The overall structure can resist compression and deformation, effectively protect products, and reduce express delivery costs. In addition, the tinplate cans used can be recycled and can be used for storage or planting green plants, which can reduce consumables, improve utilization rate, and beautify the environment.

Description

Technical field: [0001] The invention relates to a packaging method for tea or herbal tea, and mainly relates to a nitrogen-filled and fresh-keeping packaging method for high-efficiency and environment-friendly tea or herbal tea and a production process thereof. Background technique: [0002] Tea drinking in my country has a long history, and tea packaging can be traced back to the Tang Dynasty more than a thousand years ago. Traditional tea packaging methods include wooden, bamboo, and pottery packaging. Today, there are various forms of tea packaging, which can be roughly divided into hard packaging, semi-rigid packaging, soft packaging, etc., hard packaging includes bottled, canned, wooden or bamboo packaging, etc.; Cartons; flexible packaging is mostly soft cartons, plastic bags, etc. [0003] At present, most of the tea packages sold on the market are rigid packages or kraft paper packages. The cost of kraft paper packages is relatively low, but it is not conducive to ...
