Embodiment 1

[0029] Collect fresh kitchen waste, separate solid and liquid to obtain solid waste and liquid waste, and pick out impurities such as broken glass and plastic in the solid waste.

[0030] 1. Preparation of Candida tropicalis bacterial liquid: Candida tropicalis (purchased from China Center for Type Culture Collection (CCTCC), its preservation number is: CCTCCAY92045) was obtained from Candida slant medium Pick one ring and inoculate it into the liquid Candida seed culture medium, culture at 28°C and 150 rpm for 24 hours with shaking, check the purity under the microscope, the strain is in the logarithmic growth phase, stop the culture, and obtain the first-grade strain of Candida tropicalis Then, according to the inoculation amount of 3% (v / v), it was inserted into the fermenter filled with Candida seed medium, the temperature was 28°C, the stirring speed was 250rpm, and the ventilation rate was 3L / (L·min). Time 24 hours, obtain Candida tropicalis bacterium liquid, described C...

Embodiment 2

[0041]Collect fresh kitchen waste, separate solid and liquid to obtain solid waste and liquid waste, and pick out impurities such as broken glass and plastic in the solid waste.

[0042] 1. Preparation of Candida tropicalis bacterial liquid: Pick a ring of Candida tropicalis from the Candida slant medium and inoculate it into the liquid Candida seed medium, at 30°C, 150rpm, shaking culture for 48 hours, microscopically check the purity, the strain is in the logarithmic growth phase, stop the culture, and obtain the first-class strain of Candida tropicalis; In the fermenter of the yeast seed culture medium, the temperature is 30°C, the stirring speed is 200rpm, the ventilation rate is 2L / (L·min), and the fermentation time is 24 hours, to obtain the Candida tropicalis bacteria liquid, the Candida tropicalis The slant medium contains glucose 5g / L, peptone 2g / L, yeast extract 1g / L, sodium chloride 0.5g / L, agar 20g / L, the balance is water, pH is 6.5, sterilization conditions: steri...

Abstract

The invention discloses a production method using food residues to prepare functional microorganism organic fertilizer.The production method includes the steps of a, collecting fresh kitchen wastes, and performing solid-waste separation to obtain solid wastes and liquid wastes; b, preparing fermentation substrates; c, respectively inoculating candida mycoderma bacteria, bacillus subtilis, lactobacillus and aspergillus niger into the fermentation substrates to perform first fermentation compost; d, turning piles and inoculating bacillus subtilis, pseudomonas fluorescens and streptomyces, turning piles, fermenting, and drying with cold air to obtain the finished functional microorganism organic fertilizer, wherein pH is 6.5-7.5, and moisture content is 35-50%.The production method has the advantages that the food residues are processed reasonably, and the functional microorganism organic fertilizer is prepared at low cost; the food residues are processed reasonably and thoroughly, the functional microorganism organic fertilizer with high practicality and high value is produced by using the functional strains, the utilization value of the wastes is maximized, and the method is green and free of pollution.

Description

technical field [0001] The processing machine of the invention belongs to the field of microbial fermentation, and in particular relates to a production method for preparing functional microbial organic fertilizer by utilizing food waste. Background technique [0002] Catering waste, also known as food waste, refers to the waste generated in the process of kitchen food processing and the leftover food on the dining table. It is a kind of domestic waste in the process of residents' living consumption. Restaurants are 50% each. Mainly include: rice and flour food residues, vegetables, vegetable oil, animal oil, meat bones, fish bones, etc. From the chemical composition, there are starch, cellulose, protein, lipid and inorganic salt. Among them, the organic components are the main components, containing a large amount of starch and cellulose, the content of NaCl in the inorganic salt is relatively high, and a certain amount of calcium, magnesium, potassium, iron and other tra...
