[0008] The invention uses the edible fungus residue as the raw material for papermaking, which not only solves the problem of processing the residue, but also does not apply the residue to pulp and paper in the prior art. This method creatively applies it to pulp and paper, Alleviating the shortage of papermaking raw materials, the paper made is not only of high quality and meets people's needs, but also has a high utilization rate of raw materials

Embodiment 1
[0038] 1 Mushroom residue raw material
[0039] There are many raw materials for shiitake mushroom cultivation, mainly fruit trees such as peach wood, plum wood, apple wood, hard miscellaneous wood such as elm, and wheat bran and other mixed materials. In addition to cellulose, hemicellulose, polysaccharides and other substances, these raw materials also contain organic matter such as protein and amino acids necessary for edible fungi. They are rich in nutrients and meet the needs of the growth of shiitake mushrooms. Unlike the raw materials commonly used in pulp and papermaking (such as poplar, eucalyptus, pine, etc.), these woods are hard, have short fibers and relatively low cellulose content.
[0040]Edible fungus cultivation generally goes through the following processes: raw material mixing, bagging of mushroom sticks, high-temperature sterilization, strain inoculation, management of mushroom production, harvesting, culture of bacteria, and secondary fruiting. In the pr...

[0096] The prepared slag mechanical pulp was used to produce degradable nursery cups.
[0097] Edible fungus slag mechanical pulp is used to produce pulp molding products such as vegetables, seedling cups, seedling trays, etc. Seedling cups (trays) are 1-2mm thick, with water retention, heat preservation and water resistance properties. When transplanting, the seedlings are transplanted together with the pot, which saves the process of removing the pot, saves labor and time, does not hurt the seedlings, and is beneficial to the survival of the seedlings , Pulp degradable seedling cups can completely replace plastic seedling cups. Edible mushroom residues are rich in nutrients, which are retained during the pulping process. Pulp seedling cups are easy to biodegrade, and the nutrients in the mushroom residues become a source of nutrition for crops without causing environmental pollution. The seedling cup itself has good dry and wet strength.

Abstract
The invention discloses a pulping method of edible fungus residue. The method includes the steps of: (1) crushing an air-dried fungus residue rod into small pieces and removing debris; (2) performingpretreatment: at room temperature, soaking the crushed fungus residue in water in a mass ratio of 1:3-1:6 for 30-60min, and then raising the temperature of the fungus residue to 95-100DEG C, fully stirring the substances, and conducting heat preservation for 30-50min; (3) conducting pulp refining: subjecting the pretreated fungus residue to staged pulp refining, and controlling the pulp refining concentration at 15-30%; and (4) performing screening: after pulp refining, employing a slot pulp screen for screening treatment, and controlling the screening slotted opening width at 0.25-0.5mm, thusobtaining mechanical pulp meeting quality requirements. The pulping papermaking process is mature, the waste environmental protection treatment is stable and reliable, and the waste liquid, waste residue and the like produced by fungus residue pulping are easy to dispose. The prepared mechanical pulp is applicable to papermaking and agricultural aspects, and can be used for producing packaging corrugating medium and degradable agricultural seedling culture cups.
Description
technical field [0001] The invention relates to a pulping method of edible fungus residue, and belongs to the technical field of utilization of edible fungus cultivation waste. Background technique [0002] In recent years, my country's edible fungus industry has developed rapidly, and its production capacity has increased rapidly, gradually realizing the industrialization, industrialization and scale of edible fungus breeding and processing. my country is a big producer of edible fungi, accounting for more than 70% of the world's total output of edible fungi. Simultaneously, the waste produced by the cultivation of edible fungi is also increasing, and the waste of edible fungi is about 15.8 million tons every year. Due to the complex types of fungal residues, the comprehensive utilization rate of fungal residues in my country is low, and most of the fungal residues are randomly stacked or burned, which not only causes environmental pollution, but also breeds miscellaneous ...
