Problems solved by technology

[0003] Although there are many methods and reports on the recycling of tea dregs, the stock of tea dregs is still very large. It is still of great economic importance to study new methods of recycling tea dregs to alleviate the environmental cleaning pressure brought about by tea dregs. Value and significant environmental significance

Embodiment 1

[0036] This example prepares tea paper for writing with a paper machine, and the specific method is as follows:

[0037] 1) drying the recovered tea dregs, then grinding and pulverizing, and sieving to obtain 60-80 mesh tea dregs powder;

[0038] 2) Mix 20kg of tea residue powder with 50kg of wood pulp raw material and 30kg of asparagus forage to make pulp;

[0039] 3) The paper pulp of step 2) is sent into a paper machine, and prepared into a grammage of 40-200g / m 2 commodity paper.

[0040] The paper machine used in this example is a 1575 paper machine, which was transformed after many years of exploration. The principle is different from other ordinary paper machines. The paper machine in this example is replaced by artificially woven bamboo curtains at the wire part, which completely imitates the papermaking of handmade paper. molding technology. Moreover, after the paper is pressed, it is sent to the link of the drying section to ensure that the paper is not wrinkled o...

Embodiment 2

[0059] In this example, tea paper for writing is prepared by hand-made paper, and the specific method is as follows:

[0060] 1) drying the recovered tea dregs, then grinding and pulverizing, and sieving to obtain 60-80 mesh tea dregs powder;

[0061] 2) Mix 10kg of tea residue powder with 50kg of wood pulp raw material and 20kg of asparagus forage to make pulp;

[0062] 3) The paper pulp of step 2) is handmade into paper, and prepared into a grammage of 40-200g / m 2 commodity paper.

[0063] This example is produced by pure manual process, the paper is relatively soft and breathable, and the printing and writing effect is better. The specific process of manual papermaking is as follows:

[0064] 1) rinsing, passing the prepared pulp into the bleaching tank for rinsing to remove impurities;

[0065] 2) Papermaking, the pulp after rinsing is transported to the vat through pipelines, and papermaking is formed by manual bamboo curtains using the "wave-beating method";

[0066]...

Abstract

The invention discloses a method for recycling tea leaf residues and tea paper for writing. The method for recycling tea leaf residues comprises the following steps that (1) the tea leaf residues are dried, grinded and smashed, and tea leaf residue powder of 60-80 meshes is obtained by screening the tea leaf residues; (2) by weight, 10-20 parts of tea leaf residue powder, 30-50 parts of wood pulp raw materials and 20-30 parts of Chinese alpine rush materials are mixed evenly to prepare paper pulp; and (3) the paper pulp is fed into a papermaking machine or traditional paper picking is conducted, and commercial paper with the gram weight being 40-200 g / m<2> is obtained. According to the method, the tea leaf residue powder and the wood pulp raw material are mixed to prepare the paper pulp, the commercial paper suitable for writing is produced, a new means and a solution are provided for recycling of the tea leaf residues, the environment cleanliness pressure caused by the tea leaf residues is relieved, and great economic value and great significance in environmental protection are achieved. The tea paper for writing has a faint fragrance of tea and has a good sensory effect, the tea leaf residues are applied by a large scale, the wood pulp raw materials are saved, and the papermaking cost is effectively reduced.

Description

technical field [0001] The present application relates to the field of recycling tea residues, in particular to a method for recycling tea residues, and tea paper for writing obtained based on the method. Background technique [0002] Tea is an advantageous specialty resource in our country. The deep processing of tea is developing rapidly, and the by-products of tea deep processing have increased rapidly, but they have not been effectively recycled, which has caused great pressure on environmental cleanliness. Tea dregs are the solid waste after tea soaking and extraction, and also the most important by-product of deep processing of tea deep processing enterprises. Although there are reports that the organic-inorganic compound fertilizer made from tea dregs can significantly promote the growth of new shoots of crops and improve the yield and quality of crops; its economic benefits are still unsatisfactory. There are also reports of innovative models of making mosquito coil...
