Abstract
The edible desiccant is prepared through mixing water absorbing material and supplementary material in certain ratio, puffing in puffing machine, crushing in crushing machine, pelletizing, sieving and packing. The edible desiccant has high moisture absorption of water absorbing rate 35-150 % at 25 deg.c and 90 % RH, high water maintaining property, safety, biodegradability and other advantages. It may be used widely for moisture protection and drying of food, medicine, instrument, seed, clothing, etc.
Description
Technical field
The present invention relates to a kind of edibility drier, it is applicable to food; Medicine; Optical electron, precision instrument, instrument; Seed, processed food, tealeaves; The moistureproof drying of article such as clothes, footwear, leather and heritage archive, workmanship.
Background technology
The drier that uses at present mainly is made as raw material with silica gel, montmorillonite and quick lime.
The wettability power of silica-gel desiccant is 35% of himself weight approximately, in the bigger environment of humidity, easily breaks behind the big water gaging of absorption, and the regeneration temperature height, its application is restricted.Silica gel color and luster shape as drier is all more beautiful in addition, is eaten by mistake by child easily or is used as flavouring and eats.
The moisture pick-up properties of montmorillonite drier is better, but wherein may contain heavy metallic salt and a large amount of other impurity, even some has radioactivity, and the drier that abandons after using up can cause environmental pollution.
The quick lime drier has stronger moisture pick-up properties, absorbs the calcium hydroxide of pulverize powder behind the moisture, and just the white lime known of people as long as become powder, has not just had desiccation.If eat this kind drier by mistake, because of calcium oxide becomes release heat in the process of calcium hydroxide, can burn oral cavity or esophagus meeting water.Simultaneously, calcium hydroxide is alkalescence, oropharynx, esophagus is corrosive, as is splashed into the damage that can cause conjunctiva and cornea in the eye.
Summary of the invention
The object of the present invention is to provide a kind of edible deciccant, this drier does not have injury to skin, eyes, and eat by mistake and do not have harm, the hygroscopicity height, water holding capacity is strong, and is biodegradable.
In order to achieve the above object, technical solution of the present invention is: this edible deciccant is made up of water-absorbing material and auxiliary material, and its weight proportion is:
0.1～5 part of water-absorbing material (konjaku flour grafted propylene hydrochlorate or starch grafted acrylate or chitin grafted propylene hydrochlorate or cellulose graft acrylates or polyacrylate)
0.1～50 part of auxiliary material (rice or corn or soybean or cassava or potato or sweet potato or wheat or stalk or sawdust)
(1) water-absorbing material comprises:
A konjaku flour grafted propylene hydrochlorate (Chinese patent 1410463): in advance konjaku flour is added water after 30～60 ℃ of following gelatinizations; the passing ratio pump adds the acrylate monomers that partly neutralizes with alkali; initator (potassium peroxydisulfate or ammonium persulfate or ammonium ceric nitrate) and crosslinking agent (N; N '-methylene-bisacrylamide or epoxychloropropane or 1; the 4-butanediol); stir and feed nitrogen or argon shield; after 30～70 ℃ of initiation grafting copolyreaction; follow the reactant liquor injection to enter helix tube type turbulent flow reactor with nitrogen or argon gas and carry out graft copolymerization; react after 30～300 seconds; spiral is extruded and is sent into drum-type film forming drier, makes reactant be membranaceous drying.Dry back product is the film sheet, through being ground into granular product.
B starch grafted acrylate (product)
C chitin grafted propylene hydrochlorate (product)
D cellulose graft acrylates (product)
E polyacrylate (product)
(2) auxiliary material comprises:
F rice starch (product)
G cornstarch (product)
H soybean (product)
I cassava (product)
J potato (product)

L wheat (product)
M stalk (product)
N sawdust (product)
The edible deciccant preparation process is: water-absorbing material and auxiliary material mixed in stirring mixer, and expanded in bulking machine then, go in the pulverizer and pulverize, granulation then, screening divides packing by quantitative racking machine, obtains edible deciccant.This product must add before use and pack airtight preservation.
Do not add auxiliary material, a kind of or water-absorbing material that is mixed arbitrarily of above-mentioned raw materials all can be realized the present invention.
The present invention compares with existing drier, has the following advantages:
(1) natural plant raw material, green product;
(2) nonpoisonous and tasteless, eat by mistake and do not have harm;
(3) eyes, skin there is not injury;
(4) hygroscopicity height, water holding capacity are strong;
(5) environmental friendliness, biodegradable.
