Embodiment 1

[0021] A kind of method that utilizes garlic peel to make paper pulp, is to realize through the following steps:

[0022] (1) Pretreatment: Get 200 g of garlic skins, add them to 2000 g of tap water for cleaning, and dry them at 50° C., put the dried garlic skins into a 2% NaOH solution, soak them for 2 hours, spare;

[0023] (2) Cooking: Put the garlic skin obtained in step (1) together with the soaking liquid into the reactor, set the reaction temperature to 120°C, and process it under stirring for 2 hours. After the reaction is completed, take out the slurry and filter it with a sieve squeeze dry, reserve;

[0024] (3) Cleaning and screening: the slurry obtained in step (2) is cleaned and squeezed dry, diluted with water to a concentration of 2%, beaten with a beater, and then filtered out impurities using a 100-mesh sieve, and then obtained on the sieve The pulp is dried at 60°C to obtain the pulp.

Embodiment 2

[0026] A kind of method that utilizes garlic peel to make paper pulp, is to realize through the following steps:

[0027] (1) Pretreatment: take 200 g of garlic skins, add them to 10000 g of tap water for cleaning, and dry them at 80° C., put the dried garlic skins into a 5% NaOH solution, soak them for 6 hours, and set aside;

[0028] (2) Cooking: transfer the garlic peels obtained in step (1) together with the soaking solution into the reactor, set the reaction temperature to 170°C, stir for 4 hours, and wait for the reaction to be completed, filter, squeeze dry, and set aside;

[0029] (3) Cleaning and screening: wash and squeeze the slurry obtained in step (2), add water to dilute to a concentration of 5%, beat with a beater, filter with a 150-mesh sieve to remove impurities, and dry at 90°C. Pulp can be obtained.

Embodiment 3

[0031] A kind of method that utilizes garlic peel to make paper pulp, is to realize through the following steps:

[0032] (1) Pretreatment: Take 200 g of garlic skin, add it to 6000 g of tap water for cleaning, and dry it at 65° C., put the dried garlic skin in NaOH solution, soak for 4 hours, and set aside;

[0033] (2) Cooking: transfer the garlic peels obtained in step (1) together with the soaking liquid into the reactor, set the reaction temperature to 150°C, stir for 2 hours, and wait for the reaction to be completed, filter, squeeze dry, and set aside;

[0034] (3) Cleaning and screening: wash and squeeze the slurry obtained in step (2), add water to dilute to a concentration of 3.5%, beat, filter with a 120-mesh sieve to remove impurities, and dry at 75°C to obtain pulp .

Abstract

The invention discloses a method for manufacturing pulp by using garlic slices, belonging to the technical domain of regenerating and utilizing of waste resources. The pulp is produced by pretreating, stewing, cleaning and screening the waste garlic slices taken as raw materials. According to the method, the comprehensive utilization of the waste garlic slices is realized, the production process is simple, the practicability is strong, and the additional value of the product is improved. A NaOH solution is taken as a main reagent, so that the pulp is cheap and available, and free of toxicity or harm, the treatment cost can be reduced, good economic and environmental benefits are obtained when resources are saved, and high efficiency, high quality and pollution-free utilization of resources are achieved.

Description

technical field [0001] The invention relates to a method for making paper pulp, in particular to a method for making paper pulp by using garlic peels. Background technique [0002] In recent years, the garlic planting area in my country has shown an overall upward trend. In 2008, my country's garlic planting area reached 694,000 hectares, accounting for 56.6% of the world; before 2010, my country's garlic production areas reached more than 70; in 2011, my country's garlic planting area reached about 700,000 hectares, accounting for 56.6% of the global garlic planting area. More than 60% of. The main production bases of garlic in my country are concentrated in Shandong, Henan, Jiangxi, Guangxi, Anhui and so on. [0003] According to statistics from the Food and Agriculture Organization of the United Nations, China's garlic output has risen from 5.81 million tons in 1998 to 10.58 million tons, accounting for more than 70% of the world's total output. Our country's garlic ind...
