Abstract
A preparation method of tea residue fiber raw materials includes steps of (1) sun-drying tea residues, crushing the sun dried tea residues, and treating them with concentrated hydrochloric acid and a strong base in succession; (2) extracting water from the treated tea residues to obtain tea polyphenols and pulp respectively, cooking the pulp, and then pressing and dehydrating it to obtain coarse pulp; (3) sequentially grinding and sieving the pulp, and beating it; and (4) adding β-cyclodextrin, carboxymethylcellulose sodium, and reinforced starch after the beating, adjusting the pH to 7-8, diluting, adding the tea polyphenols obtained in the second step, stirring uniformly, pressing and dehydrating, and drying to obtain the tea residue fiber raw material.
Claims2
A method for preparing tea residue fiber raw materials for papermaking, comprising steps of:
- Step 1:
- adding a sodium alginate-gelatin solution to tea residues to form a first mixture and allowing the first mixture to stand at room temperature for a period of time to form a room temperature first mixture;
- filtering the room temperature first mixture to form a first set of filter cakes and washing the first set of filter cakes to form washed filter cakes;
- and
- Step 2:
- adding distilled water to the washed filter cakes to form a second mixture, shaking the second mixture for 30 minutes to 1 hour to form a shaken mixture, filtering the shaken mixture to form a second set of filter cakes, and drying the second set of filter cakes,
- wherein the tea residues comprise any one or any combination of tea stems, tea leaves, tea tailings, tea residues resulting from brewing, or any defective products produced during a tea production process.
