Embodiment 1

[0049] A method for rapid reduction and resource utilization of fruit processing solid waste, the steps are:

[0050] The apple residue after squeezing the juice was selected as the raw material. After adjusting its moisture content to 30%, it was placed in a hydrolysis reactor for hydrolysis reaction. The reaction temperature was 198°C and the reaction time was 10 minutes. After the reaction is over, the pressure in the reactor is quickly released, and the wet decomposition material is sprayed into the collection tank. Add 20% cow dung, 6% rice bran, 2% urea and 2% ammonium sulfate according to the weight of wet-decomposed apple pomace, adjust the carbon-nitrogen ratio to 25:1-35:1, and adjust the moisture content of the material to 60%. Add 0.1% compound fermenting bacterial agent (Bacillus licheniformis, photosynthetic bacteria, thermoactinomycetes, Trichoderma viride) and 0.01% compound enzyme (cellulase, xylanase, pectinase, saccharification enzyme, protease) by mixed mat...

Embodiment 2

[0052] A method for rapid reduction and resource utilization of fruit processing solid waste, the steps are:

[0053] Select orange peel as raw material, adjust its water content to 50%, add 2% by weight of ammonium chloride as a catalyst, and place it in a wet decomposition reactor for wet decomposition reaction. The reaction temperature is 198°C and the reaction time is 10 minutes. After the reaction is over, the pressure in the reactor is quickly released, and the wet decomposition material is sprayed into the collection tank. Add 20% of its weight to pulverize wheat straw and 3% corn flour by the weight of the wet-decomposed apple pomace, after fully stirring and mixing, add 0.1% of the mixture weight compound bacterial agent (saccharomyces cerevisiae, candida utilis, lactobacillus plantarum, animal bifidum Bacillus, Geotrichum candidum), compress and seal the evenly mixed materials, pack and ferment at room temperature for 15 days to obtain biological feed products.

Abstract

The invention relates to a method for rapid reduction and resource utilization of fruit processing solid waste. The method for rapid reduction and resource utilization of the fruit processing solid waste comprises the steps that the fruit processing solid waste is smashed, water or a chemical catalyst is added for pre-dip treatment, then the mixture is placed in a hydrothermal degradation reactor,saturated steam is introduced in the mixture for hydrothermal degradation treatment, after the reaction is finished, the pressure in the reactor is quickly removed, and a material subjected to hydrothermal degradation is collected; and after the material subjected to the hydrothermal degradation is mixed with an auxiliary material, an organic fertilizer is produced by aerobic solid-state fermentation, or biological feed is produced by anaerobic solid-state fermentation. A wide application range of raw materials, no special dry processing, high product yield, fast and stable production processand no pollution are achieved, large-scale industrial application is easily realized, and the purpose of rapid reduction and resource utilization of fruit processing solid waste can be realized.

Description

technical field [0001] The invention belongs to the technical field of resource utilization of fruit processing waste, in particular to a method and application of rapid reduction and resource utilization of fruit processing solid waste. Background technique [0002] Fruit is the main agricultural product in the world, and China is the largest fruit producing and processing country in the world. my country's fruit industry has developed into the third largest agricultural pillar industry after the grain and vegetable industry, and it is also an industry with significant advantages and international competitiveness in my country's agricultural product processing industry. However, due to the constraints of many unstable factors such as raw material quality, process technology and product requirements, a large amount of processing waste is generated in the process of fruit processing, which accounts for more than 30% of the total raw material. Fruit processing solid waste ref...
