Problems solved by technology

However, the moisture content of citrus pomace is more than 80%, and it is rich in pectin, and a large amount of water exists in the form of bound water. Drying pomace consumes a lot of energy and costs, making it difficult to be widely used.
In addition, the protein mass fraction of citrus pomace is less than 1% (dry mass basis), and the nutritional value of the feed is low
Chinese patent CN101857510B discloses a kind of orange pomace organic compound fertilizer for citrus and its preparation method. It adopts the method disclosed in Chinese patent ZL200710093221.8 titled "A Bacillus megaterium and its application and application method in enzyme bacteria". , and preserved in the China General Microorganism Culture Collection Management Center, the preservation number is CGMCCNO.2267 Bacillus megatherium M1 (Bac.megatherium.M1) is an acid-resistant and high-temperature-resistant microbial active substance obtained through conventional microbial expansion and cultivation— Orange SlagFermentation (OrangeSlagFermentation) is used for fermentation treatment by OSF fermentation bacteria, but the bacteria can only carry out saccharification and amino acid decomposition, and there is no specific disclosure on the degradation of pectin and cellulose, the main components of citrus pomace. Active ingredients are not fully utilized
Chinese patent CN103396235A discloses a method of using citrus peels to produce organic fertilizers. Bacillus subtilis is used for fermentation, which can only treat the pectin in citrus peels, and the active ingredients of citrus are still not fully utilized. It can be seen that citrus The biological fermentation effect of skin dregs is closely related to the types of microorganisms and their physiological and metabolic characteristics

Abstract

The invention discloses an orange peel dregs biologic fermentation method, and belongs to the technical field of orange peel dregs innocuous treatment. Orange peel dregs are used as a main raw material and added with a liquid micro organism bacterial agent, and is subjected to composting primary fermentation and composting fermentation, so as to prepare a fermentation product which is rich in organic substances and microelements such as boron, zinc and magnesium, and is proper in the proportions and contents of N, P and K. The content of the organic components of the fermentation product is not less than 45 percent, the pH value is within 6.5-8.5, the total content of N, P and K is not less than 6 percent, the moisture content is not greater than 30 percent, the fermentation product is rich in the microelements such as boron, zinc and magnesium, can be directly used as an organic fertilizer, meanwhile can be added with a microelement fertilizer or a chemical fertilizer to be compounded into an organic compound fertilizer, an organic-inorganic compound fertilizer and the like. The orange peel dregs biologic fermentation method is simple in process, low in cost and high in production efficiency, not only processes a large amount of orange peel dregs, but also prompts the treatment of other organic waste materials, so as to not only protect the environment, but also increase the economic benefits, achieve low-carbon production and explore a new method for the innoxious treatment of the orange peel dregs.

Description

technical field [0001] The invention relates to the harmless treatment of citrus peels, in particular to a biological fermentation method of citrus peels. Background technique [0002] my country is the world's largest producer of citrus. In addition to direct consumption of citrus, a considerable part of citrus is used for juice processing, resulting in a large amount of citrus peel. Currently, citrus peels are mainly disposed of through simple sanitary landfills. However, the skin dregs are large in size and high in water content. Landfill treatment not only takes up a lot of land, but also produces a large amount of seepage and odor, causing a series of environmental pollution to the surrounding air, soil and water, and seriously affecting people's production. , life and health, the harmless treatment and resource utilization of citrus peels need to be solved urgently. [0003] Citrus peel is rich in water, pectin, cellulose and mineral elements, and also contains a sm...
