Abstract

The present invention utilizes the crustaceans, such as tainted shrimp, dead crab, grasshopper and silkworm chrysalis, etc, and makes them undergo the process of hydrolysis reaction under the alkaline condition so as to obtain amino acid, and makes crust undergo the process of hydrolysis reaction under the acidic condition to obtain aminoglucose hydrochloride. After two solutions are neutralized, the secondary and trace elements necessary for crops are added to make chelation reaction so as to obtain the invented composite foliage fertilizer.

Description

Utilize weste crustacean and crust thereof to produce amino acid foliage fertilizer

The present invention relates to a kind of weste crustacean and crust thereof of utilizing and produce amino acid foliage fertilizer.

The crustacean aboundresources of China, coastland and big, the rotten dead crab enormous amount of dead shrimp of area, middle and lower reach of Yangtze River shrimp crab output.In the food processing process, shrimp and crab shells except a part be used to produce chitin and extension product major part thereof go out of use need not.China always has partial area that the plague of locusts takes place every year, and every square metre can reach thousands of when the plague of locusts took place, and all fails to obtain after a large amount of locusts dies like a rat to utilize, and also has silkworm chrysalis etc., all is sources of crustacean.Crustacean also contains a large amount of protein except containing chitin in the body.The objective of the invention is to make full use of this natural resources and produce amino acid foliage fertilizer." Jiangsu chemical industry " paper " DEVELOPMENT PROSPECT of chitin and derivative thereof " that the 5th phase delivered in 2002, the production method and application present situation and the DEVELOPMENT PROSPECT of product in medicine, food, daily use chemicals, agricultural, environmental protection, papermaking, weaving of chitosan and derivative thereof have been introduced, " agricultural chemicals " magazine the 4th phase of calendar year 2001 " Application and Development of chitin on agricultural ", to the mechanism of action of chitin and derivative thereof with and the key areas that is applied to agricultural done introduction.Common ground is to be to be applied to agriculture field with shrimp and crab shells after as raw material chitin extraction and derivative thereof, and the protein in shrimp and crab shells and the Crustacean and other organic substance are all given it up.Chinese patent application 97112535.X discloses a kind of middle trace-element compound fertilizer and preparation method thereof.This composite fertilizer comprises the required N of crop growth, P, K and moderate-element Ca, S, Mg, Si and micro-Fe, Mn, Zn, B, also contains housing and the remaining marine organisms of part of Crustacean.This invention is not done chemical treatment to Crustacean, thereby can only be as the raw material of composite fertilizer, Chinese patent application number 01128811.6 discloses " a kind of method for preparing leaf fertilizer by chelating amino acids with trace elements ", be characterized in the animal/vegetable protein being raw material, through hydrolysis, neutralization, desalination, chela and, process such as spraying drying makes aminoacid chelating microelement; Chinese patent application numbers 92106896.4 discloses a kind of organic amino acid trace-fertilizer and production technique, has introduced blood from the slaughterhouse, hair, the coffin the like waste and has extracted the method that amino acid is made organic little fertilizer.Do not see the report that utilizes crust and crustacean to produce amino acid foliage fertilizer.

Technology of the present invention is with crust and crustacean, the aquatic products tankage are raw material, crust is generated amino acid and glucosamine hydrochloride with hydrochloric acid hydrolysis, in addition with crustacean and other aquatic products tankage KOH hydrolysis, make it to generate basic aminoacids, its isolated crust neutralizes two liquid for hydrochloric acid hydrolysis, trace elements such as chelating Fe, Cu, Mn, Zn are deployed into amino acid foliage fertilizer at last again.With the amino acid foliage fertilizer technology advantages of simple that this method is produced, cost is low, not only contains the hydrolysate glucosamine hydrochloride that 20 multiple amino acids and multiple middle trace element also have chitin in its product.Because of glucosamine hydrochloride contains-NH ₂The band positive charge not only has the function that stimulates plant growth, also has sterilization efficacy, and is without any side effects.The effect of existing raising crop yield of its amino acid foliage fertilizer and quality product has sterilization effect again, improves the resistance of farm crop.

Fig. 1 is seen in technical process of the present invention

Embodiment 1

1, the filter residue 100Kg that takes by weighing behind the shrimp and crab shells 300Kg basic hydrolysis amino acid places the 1000L enamel reaction still, and the hydrochloric acid 500L that puts into 25-33% is in header tank.The salt slow acid is added reactor, open cooling and reflux device.It is fierce to begin reaction, and the speed of hydrochloric acid is accelerated to add in the relatively milder back of question response, and the adding speed of hydrochloric acid is not overflowed degree of being with reaction solution.After hydrochloric acid added, the passageway was steam heated to boiling, kept 3-4 hour, cooling, filtered, and was discharged to plate-and-frame filter press and removed residue, and it is standby that clear liquid is that acidic amino acid mixed solution (I) is put into the storage pond.

2, take by weighing crustacean, smelly shrimp, dead crab or locust 500Kg, add in the 1000L carbon steel reactor, adding concentration is 8% KOH solution 500Kg, is heated to 90-100 ℃ of reaction 2 hours.Filter, remove residue, it is standby that stillness of night basic aminoacids liquid (II) is put into the storage pond.

3, with above-mentioned basic aminoacids liquid (II) 1000L, squeeze in the 2000L enamel reaction still, progressively adding acidic amino acid mixed solution (I), to be neutralized to PH be that 3-4 is reaction solution (III).

4, the inorganic salt of trace elements such as adding Fe, Cu, Mn, Zn, B make micro-total amount 〉=2% in reaction solution (III), after chelatropic reaction 3-4 hour, add mixings such as thickening material, bio-hormone, tensio-active agent, product is amino acid foliage fertilizer of the present invention.
