Process for producing organic fertilizers with fruit residues as main material

Abstract

The invention discloses a process for producing organic fertilizers with fruit residues as a main material. The process includes steps: using a grinder for grinding fruit peels into 1-2cm fruit residues, adding a deodorizing agent, and completely mixing to obtain mixed material powder; grinding organic auxiliary materials by the grinder to obtain organic auxiliary material mixed powder; well stirring the mixed material powder and the organic auxiliary material mixed powder, adding activated coarse fiber degradation complex bacteria, stacking for ridging, and covering with straw mats to realize coarse fiber degradation; adding a composting complex bacterium expanding culture agent, and spreading a small quantity of pesticides; spreading out for airing after turning, measuring the moisture content, allowing fermented materials to enter a finished product workshop, and performing grinding, stirring, screening and packaging to obtain finished products of the organic fertilizers with fruit residues. The process has advantages that waste orange peel residues are made into the organic fertilizers through harmless biological fermentation, and the biological organic fertilizers meeting plant growth can be obtained by conversion after fermentation; since the raw materials are all recovered materials, environmental friendliness is achieved.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer production, in particular to an organic fertilizer production process with fruit pomace as the main raw material. Background technique [0002] In recent years, with the continuous expansion of citrus planting area, my country has become the largest orange juice processing base in Asia, and the processing capacity and quantity of orange juice processing plants are huge. After citrus is squeezed for juice, the resulting pomace waste accounts for about 50% of the citrus. A large-scale citrus processing enterprise currently produces about 25,000 tons of citrus peels every year. The discarded citrus peels are mainly disposed of through simple landfills, which occupy a lot of land and produce a large amount of seepage and odor. Environmental pollution and waste of resources. The discarded citrus peels produced by fruit juice processing are large in volume, high in water content, and cause ...

AI Technical Summary

Problems solved by technology

The water content of citrus peel is more than 80%, and it is rich in pectin. A large amount of water is absorbed, and the energy consumption of drying peel residue is very large. Drying 1 ton of orange residue requires 1 ton of coal, plus the cost of electricity, labor, and depreciation of enterprise equipment. , the cost remains high. In addition, the protein content of citrus pomace is very low, and its nutritional value as feed is not enough. Therefore, the promotion process is slow

[0004] At present, most of the domestic citrus peels are still disposed of in a concentrated manner, which seriously increases the burden on the environment. The waste of citrus residues is increasing year by year, and it has also become a bottleneck for industrial development.
