Amorphophallus glucomannan drying agent and preparation method thereof

Abstract

The invention relates to an amorphophallus glucomannan drying agent which consists of amorphophallus glucomannan, propenoic acid, sodium hydroxide, ethanol, hydrochloric acid, potassium persulfate, N,N-methylene-bisacrylamide, calcium chloride and water. The preparation method of the drying agent comprises the steps of: preparing deacetylation amorphophallus glucomannan and deacetylation amorphophallus glucomannan-propenoic acid copolymer; mixing the deacetylation amorphophallus glucomannan and the deacetylation amorphophallus glucomannan-propenoic acid copolymer according to a proportion; andcrushing and pelleting after expansion. The drying agent has the advantages of reasonable formula, low cost, strong water absorption, safety, no toxicity, no harm to skin and eyes, biodegradability and the like, and can be widely applied to the fields such as food, medicine, chemical industry and the like.

Description

technical field [0001] The invention relates to a desiccant and a preparation method thereof, in particular to a konjac glucomannan desiccant with konjac glucomannan as a main raw material and a preparation method thereof. Background technique [0002] In view of the traditional desiccant, silica gel, quicklime, molecular sieve and polymer water-absorbing agent are often used as the main raw materials. However, due to their own shortcomings, such as the low water absorption capacity of silica gel, the water absorption can easily reach saturation at high humidity; quicklime gradually becomes an aqueous solution during the moisture absorption process; Wide application in other fields. Therefore, the research of a new type of desiccant has attracted much attention, especially the edible desiccant has become one of the hot spots in the development of the desiccant manufacturing industry. The new generation of desiccants use natural materials as raw materials, which can be divi...
