Problems solved by technology

[0003] At present, most of the raw materials for organic fertilizer production are prepared from poultry manure and crop waste, but there are problems such as low nutrient content required by crops, low quality of finished products, and low absorption and utilization rate of crops. Therefore, we propose a Method for increasing protein in biomass raw materials by fermentation of food leftovers

Abstract

The invention discloses a method for improving protein in a biomass raw material through kitchen residue fermentation. The method comprises the following steps: pulverizing kitchen residues into particles, carrying out sterilizing, cooking the kitchen residues by using an acidic solution, and carrying out water bath heat preservation treatment on the kitchen residues in an alkaline solution; then,inoculating a microbial fermentation agent for composting natural fermentation, and adding 10 parts of mushroom dregs for constant-temperature secondary composting fermentation; and finally, pouringthe mixture into a granulator for granulation and molding. According to the method for improving the protein in the biomass raw material through kitchen residue fermentation, relaxation of cell wallsof the kitchen residues is promoted, the permeability of the kitchen residues is improved, various organic matters are fully degraded through secondary fermentation treatment, and the organic mattersare converted into organic nutrients capable of being absorbed by soil and plants, so that the absorption and utilization rate of crops is promoted and is higher than the national biomass raw materialindex, and the quality of the crops is further improved.

Description

technical field [0001] The invention relates to the technical field of biomass raw material preparation, in particular to a method for increasing protein in biomass raw materials by fermentation of kitchen residues. Background technique [0002] Biomass raw material is a kind of biomass resources. With the continuous improvement of people's awareness of healthy food and land protection, it is processed from plants or animals through biomass, animal and plant waste, and plant residues, and is rich in a large amount of beneficial Substance organic fertilizer is widely used in the cultivation of crops. It has a long fertilizer effect, can improve the physical and chemical properties and biological activity of the soil, and is the main nutrient for green food production. [0003] At present, most of the raw materials for organic fertilizer production are prepared from poultry manure and crop waste, but there are problems such as low nutrient content required by crops, low qualit...
