Description

Water-soluble fertile desiccator of using of fish protein amino acid

Technical Field

The utility model relates to a fertilizer processing equipment field specifically is a desiccator is used to water-soluble fertile of fish protein amino acid.

Background

With the development of marine fishery and aquatic product processing industry in China, abundant low-value fish resources and aquatic product processing leftovers become important green ecological organic fertilizer sources. The amino acid decomposed from fish protein can be used as basic structural unit of life for directly synthesizing protein, nucleic acid and individual endogenous hormone by crops, and can enhance the metabolism and stress resistance of crops. The amino acid fertilizer can also improve the physical and chemical properties of soil, improve water retention, fertility retention and air permeability, and play roles in maintaining, curing and improving soil.

The solid content of the amino acid liquid water-soluble fertilizer generated by degrading the fish protein is generally 10-18%, the content of free amino acids is 2.5-10%, the free amino acids comprise more than ten kinds of amino acids such as aspartic acid, threonine and serine, and the fertilizer is rich in organic matters and nutrient elements such as nitrogen, phosphorus and potassium. The fish protein amino acid liquid water soluble fertilizer is easy to grow bacteria due to high water content. Nitrogen-containing organic matters such as amino acids and polypeptides in the water soluble fertilizer are easily degraded by bacteria and decomposed into putrefactive products such as ammonia, trimethylamine, indole, hydrogen sulfide and histamine. Therefore, the fish protein amino acid liquid water-soluble fertilizer is not easy to store for a long time, and is more easy to decay and deteriorate particularly under hot weather conditions. Liquid fertilizers are generally higher in packaging cost than solid fertilizers, and are generally packaged by barrels, bottles and non-leakage plastic bags. And the liquid fertilizer has larger volume than the solid fertilizer, so the transportation and storage cost is higher. In order to enable the fish protein amino acid water-soluble fertilizer to be widely applied, the liquid water-soluble fertilizer is preferably dried and stored. In the prior art, the drying modes of the liquid water-soluble fertilizer comprise three types: counter-current, parallel, and mixed. The countercurrent type is not suitable for drying and granulating heat-sensitive materials such as fish protein amino acid liquid water-soluble fertilizer containing heat-sensitive amino acid components because the material is suspended in the drying chamber for a long time; the parallel flow type is suitable for materials with low moisture content because the hot air flow and the spray liquid are in parallel flow and the mutual contact and heat exchange time is short, and the materials with high moisture content, such as fish protein amino acid liquid water-soluble fertilizer with solid content of only 10 percent, can not be completely dried in a parallel flow structure; in the mixed type, because the airflow direction is mixed and superposed, the stress and heating generated when the mixed type is contacted with the liquid water-soluble fertilizer are uneven, so that the dry particles are uneven, and the granulating effect is not ideal.
