Abstract
A production method of amino acid chelate compound environmental protection fertilizer by using discarded protein or farm and side line products containing high protein ratio as raw material through the steps of, acidification, electrodialysis deacidification, hyperfiltration concentration into 50% of composite amino acid solution, separating amino acid with high content by means of electrochemical method, using mother liquor as sequestering agent, chelating with trace element and rare-earth element of a finite proportion, charging N, P and K for recombination, then obtaining the end product through drying, disintegrating and quantitative packaging.
Description
1, technology contents
The present invention relates to a kind of by discarding the high protein thing or containing the production method that the high protein agricultural byproducts are made raw material extraction aminoacids complex and produced composite environmental-friendly fertilizer with amino acid as sequestrant.Its advantage is to make full use of the waste protein resource, for new channel is opened up in the agricultural byproducts deep processing.Amino acid is as sequestrant; raw material sources are extensive; cheap; contain carboxyl and amino two kinds of functional groups in its molecule; it is a kind of ideal ligand; very easily with the essential trace element of crop growth and rare earth element chelating and form the bidentate title complex, and stability constant is moderate, has avoided the antagonistic action between the element; be not subjected to the influence of P in soil H value and other foreign ion; need not to participate in the protein synthesis of body directly, improve crops quality, increase the yield per unit area thereby play through photosynthesis; reduce pesticide residue; sterilizing pesticide prevents that soil acidification from hardening, the effect of preserving the ecological environment.
Chelating amino acids composite environmental-friendly fertilizer is fertile more rational in infrastructure than single nitrogen, phosphorus, potash fertilizer or compound (closing), comprehensive nutrition, and more stable and do not run off than common little fertilizer, stronger than chelating abilities such as humic acid, xanthohumic acids, the fertile price of EDTA chelating that adopts than the U.S. is low.In process of production, adopt the electrodialysis depickling lower than traditional neutralisation cost, more easy and simple to handle than resin method, and reclaim the acid solution recycle, stopped environmental pollution.The employing reverse osmosis concentration is energy-saving and cost-reducing, has reduced production cost significantly.Adopt the electrochemistry settling process to separate the higher relatively simple substance amino acid of content, changed domestic and international iso-electric point neutralisation, do not introduce chemical reagent, avoided common-ion effcet, amino acid is not damaged, improve recovery rate.Whether amino acid is complete with the chelatropic reaction of trace element, rare earth element, is the key of production technology and quality product.In the determination techniques of chelation percent, at present both at home and abroad all is to record indirectly by the method for measuring free trace element, as ion electrode method, EDTA complexometry, ion-exchange-resin process etc., formality trouble and out of true.This law adopts a kind of brand-new technology directly to measure chelated microelements, and is easy, quick, accurate, is convenient in time hold in process of production quality product.
2, goal of the invention
The objective of the invention is the strong chelating amino acids agent of chelating ability for a kind of cheapness is provided; trace element, the rare earth element essential with crop growth carry out chelatropic reaction; compound with plant growth three elements N, P, K again in the science ratio; make a kind of broad spectrum type, diversification, multifunctional novel fertilizer; soil fertility is brought up to the level that adapts with farm crop physiology and economic system; for develop green, Organic food provides the new source of manure, help preserving the ecological environment and the Sustainable development of agriculture production.
3, technical scheme
With the high protein thing is raw material, through acid hydrolysis, depickling, the concentrated compositing acid solution that forms, the electricity consumption chemical deposition method carries out isolation and purification to the higher relatively simple substance amino acid of content, the inorganic salt or the oxide compound that in mother liquor, add trace element, rare earth element then in proportion, carry out abundant chelating, again by scientific matching add N, P, K carry out compound, last drying, pulverizing, quantitative package and finished product.
