Problems solved by technology

With the progress of society, the improvement of people's living standards, and the gradual enhancement of environmental protection awareness, although some of these packages are exquisitely made, they always give people a feeling of being cold and repelling people thousands of miles away; for wooden and paper packaging, Because it uses a lot of wood in the manufacturing process, it is bound to cut down a lot of forest resources, which is not good for the protection of the environment; Seldom affect the taste of the tea itself, but it is unavoidable, so if the storage time is too long, it will affect the taste of the tea

Embodiment 1

[0019] After washing the picked fresh tea leaves, add water and use a disc mill to grind them into a slurry, and control the solid content at 2%; squeeze and filter the solution with a nylon mesh filter bag; the filtered solution is evaporated and concentrated at 100°C under normal pressure to Solid content is that the concentrated solution of 20g / L is for subsequent use; The tea slurry after filtering out solution is copied into 80 grams / m by the conventional method in the prior art 2 paper; according to 50ml / m 2 Spray the concentrate on the paper that has been copied; then dry the paper at 100°C under normal pressure to make light brown wrapping paper.

Embodiment 2

[0021] After washing the picked fresh tea leaves, add water and grind them into pulp with a disc mill, and control the solid content of the pulp concentration at 20%; squeeze and filter the solution with a nylon mesh filter bag; the filtered tea pulp is made of existing technology The conventional method in the paper is copied into 100 g / m 2 Paper sheet, dry the filtered solution under reduced pressure (-0.05Mpa vacuum), control the temperature at 60°C, concentrate to a solid content of 50g / L to form a concentrated solution for later use; spray the concentrated solution back to semi-dry or dried On the dry paper, control the amount of backspray to 50ml per square meter; then dry the paper sheet under reduced pressure (-0.05Mpa vacuum) at 60°C to make a brown wrapping paper similar to dry tea.

Embodiment 3

[0023] After washing the picked fresh tea leaves, add water and grind them into pulp with a disc mill, and control the solid content of the refining concentration at 60%; squeeze and filter the solution with a nylon mesh filter bag; filter the tea pulp with the existing technology The conventional method is copied into 100 g / m 2 Paper sheet, dry the filtered solution under -0.05Mpa vacuum condition, control the temperature at 60°C, concentrate to a solid content of 80g / L to form a concentrated solution for later use; spray the concentrated solution back on the semi-dry or dried paper, Control the amount of backspray to 50ml per square meter; then dry the paper sheet under normal pressure at 100°C to make a black-brown wrapping paper similar to dry tea.

Abstract

The invention provides a processing method of special tea bag paper (a novel tea packaging material), which belongs to the field of paper manufacture. The method comprises the steps of: taking green tea leaves left on plants after tea is picked as raw materials, crushing and grounding the raw materials into heavy paste, after filtering, evaporating the filter liquor into concentrated solution, making the heavy paste into sheet paper, spraying the concentrated solution back on the sheet paper, and drying the sheet paper to obtain the special tea bag paper. Without adding any chemical medicines, the packing paper stands much closer to nature and is more environment-protective, the color of the packing paper is similar to that of dry tea, and the packing paper also has tea aroma, therefore the tea is prevented from tainting by odour.

Description

technical field [0001] The invention relates to a novel tea packaging material and a processing method of special tea paper, belonging to the technical field of papermaking. Background technique [0002] At present, the packaging of tea is mostly plastic packaging, ordinary tea wrapping paper packaging, carton (paper tube) packaging, wood product packaging, metal object packaging, glass packaging, etc. With the progress of society, the improvement of people's living standards, and the gradual enhancement of environmental protection awareness, although some of these packages are exquisitely made, they always give people a feeling of being cold and repelling people thousands of miles away; for wooden and paper packaging, Because it uses a lot of wood in the manufacturing process, it is bound to cut down a lot of forest resources, which is not good for the protection of the environment; Seldom affect the taste of the tea itself, but it is unavoidable, so if the storage time is...
