Problems solved by technology

However, the fish waste has high salt content, and heavy metals and drug residues are difficult to control. Although fish protein fertilizers are sold on the market, the processes used in these products are basically simple cooking, enzymatic hydrolysis, and separation. The content of oil and heavy metals is high, and it has a strong fishy smell. The nitrogen content of the product is low, especially the quality of the product is difficult to preserve. It is necessary to add acidic substances to adjust its pH value to about 4.0 in order to preserve the quality.
In this way, the product has been out of the category of organic fertilizer, and its use in the development of green and organic agriculture is limited

Embodiment Construction

[0029] The present invention will be further described below in conjunction with embodiment.

[0030] A kind of method that takes fish as raw material to produce water-soluble fish protein powder organic fertilizer, its specific operation steps are as follows:

[0031] 1. Raw materials

[0032] 1.1 Raw material selection

[0033] Raw fish identified for processing includes processed waste heads, scales, skins, fillets, viscera, or low-value whole anchovies from commercial fish caught in the sea, as well as freshwater cultured whole fish such as herring, Grass carp, silver carp, bighead carp and other four major carp, carp, tilapia, catfish, etc. are processed and discarded fish heads, fish scales, fish skin, fish steaks, and viscera. The raw materials selected in this embodiment include three kinds. The first kind uses the fish head, fish scales, fish steaks and viscera produced after cod processing as the representative of fish processing waste; the second kind uses the...

Abstract

The invention belongs to the technical field of organic fertilizer production. In order to fully utilize nutrient substances in offal fish and leftovers generated after fish processing, the invention provides a method for producing a water-soluble fish protein organic fertilizer from fish, which comprises the following steps: raw material treatment, fermentation and enzyme hydrolysis, physical separation, water-soluble enzymolysis solution purification treatment, concentration, drying and packaging. The production method has the advantages of severe steps and scientific parameter setting, can prevent environmental pollution generated by fish leftovers, changes the waste leftovers into valuable substances, and can implement centralized collection and treatment on the leftovers generated by aquatic product processing enterprises.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer production, in particular to a method for producing water-soluble fish protein organic fertilizer using fish as raw materials. Background technique [0002] Organic fertilizers are the development trend of agricultural fertilizers. In addition to base fertilizers, high-efficiency organic fertilizers are usually used for foliar spraying and drip irrigation. Therefore, organic fertilizers must have high water solubility. From the nutritional point of view, organic fertilizers not only need higher nutritional content, but also should retain the effect of active factors in organic matter on plant production and quality improvement, and should not contain impurities such as heavy metals that are harmful to crops. At present, the raw materials for the production of organic fertilizers mainly include 1. Agricultural waste: such as straw, soybean meal, cotton meal, etc.; 2. Livestock and poultr...
