Problems solved by technology

[0004] The problem with the existing technology is that the determination of tannic acid is relatively complicated, and generally requires the use of professional equipment such as liquid phase mass spectrometers. For recycling companies, it is not easy to make profits, and they cannot afford to purchase professional equipment.

Embodiment 1

[0028] The tea dregs that are brewed 1-3 times by themselves are used for later use.

[0029] 1) drying the recovered tea dregs in the air, with a water content of less than 20%;

[0030] 2) Separate the tea dregs from plastic, rubber, metal and glass impurities by wind separator;

[0031] 3) randomly sampling the sorted tea dregs, and punching the tea dregs obtained by sampling into tea bricks with a length, width and height of 5, 4, and 3 cm, respectively, through a mold and a punching machine;

[0032] 4) Put the tea bricks into the electric cooking pot, and put 4 tea bricks per liter of water;

[0033] 5) After boiling for more than 20 minutes, take 10 ml of tea soup for oxalic acid identification;

[0034] 6) All tea dregs are made into tea bricks for standby after identification;

[0035] 7) smear sulfur on the tea brick outer surface that step 6) obtains;

[0036] Wherein step 5) the method for oxalic acid identification is: 0.5 gram of starch (amylose) is dissolved...

Embodiment 2

[0039] The tea dregs that have been brewed by themselves for more than 30 minutes are used for later use.

[0040] 1) drying the recovered tea dregs in the air, with a water content of less than 20%;

[0041] 2) Separate the tea dregs from plastic, rubber, metal and glass impurities by wind separator;

[0042] 3) randomly sampling the sorted tea dregs, and punching the tea dregs obtained by sampling into tea bricks with a length, width and height of 5, 4, and 3 cm, respectively, through a mold and a punching machine;

[0043] 4) Put the tea bricks into the electric cooking pot, and put 4 tea bricks per liter of water;

[0044] 5) After boiling for more than 20 minutes, take 10 ml of tea soup for oxalic acid identification;

[0045] 6) If the identification fails, a special tea brick for comparison is made, and the surface is also coated with sulfur powder;

[0046] Wherein step 5) the method for identifying oxalic acid is: 0.5 gram of starch (amylose) is dissolved in the 10...

Embodiment 3

[0048] Recycle the tea dregs for later use.

[0049] 1) drying the recovered tea dregs in the air, with a water content of less than 20%;

[0050] 2) Separate the tea dregs from plastic, rubber, metal and glass impurities by wind separator;

[0051] 3) randomly sampling the sorted tea dregs, and punching the tea dregs obtained by sampling into tea bricks with a length, width and height of 5, 4, and 3 cm, respectively, through a mold and a punching machine;

[0052] 4) Put the tea bricks into the electric cooking pot, and put 4 tea bricks per liter of water;

[0053] 5) After boiling for more than 20 minutes, take 10 ml of tea soup for oxalic acid identification;

[0054] 6) all tea dregs are made into tea bricks for subsequent use if the identification is passed;

[0055] 7) smear sulfur on the tea brick outer surface that step 6) obtains;

Abstract

The invention relates to the technical field of resource recycling, in particular to a resource recycling method and a product thereof. The method comprises the following steps that recycled tea residues are aired and dried , wherein the water content is less than 20%; the tea residues, the plastic, the rubber, the metal and the glass impurities are separated by a wind power sorting machine; randomly sampling is carried out on the sorted tea residues, the sampled tea residues are punched into tea bricks through a mold and a punching machine, wherein the length, the width and height of the obtained tea residues are correspondingly 5 cm, 4 cm and 3 cm; the tea bricks are put into an electric boiling pot, and four tea bricks are put in each liter of clear water; boiling is carried out for more than 20 minutes, and 10 milliliters of tea soup is taken to carry out oxalic acid identification; all tea residues are made into the tea bricks for later use if the identification is passed; and ifnot, all the tea residues are used for composting; and the outer surfaces of the tea bricks obtained in the step 6 are coated with sulfur. According to the method, the discarded tea residues are recycled and utilized, so that novel functions such as sterilization and itching relieving are given, the energy consumption of the whole process is low, secondary pollution is not generated completely, and the method is beneficial to popularization of various large tea production areas in China.

Description

technical field [0001] The invention relates to the technical field of resource recovery, in particular to a resource recovery and reuse method and its products. Background technique [0002] There is a long history of tea drinking in China, and evidence can also be found to show that the habit of drinking tea in many parts of the world was passed down from China. Therefore, many people believe that drinking tea was first created by the Chinese, and that the habits of drinking tea and growing tea in other parts of the world were directly or indirectly passed down from China. [0003] Due to the Chinese people's strict requirements for tea, China's tea plantation area is large, but the output is very low. In addition, the Chinese generally only drink the first to third brews of tea soup, resulting in discarded tea leaves that are still rich in nutrients, resulting in a lot of waste. Because the tannic acid in tea has curative effects on beriberi and filamentous fungi, there...
