Abstract

The invention provides a plant fiber dryer which includes the following components, by mass, 91.3-96.3% of plant fibers, 3-8% of water, 0.5-2% of calcium oxide and 0.2-1% of calcium chloride. The plant fiber dryer is prepared from the pure-natural plant fibers through a special process finely, so that the plant fiber dryer has high moisture absorption rate and moisture absorption ratio. The saturate moisture absorption ratio is 100% as the weight of the plant fiber dryer itself (25 DEG C, RH is 100%) and is three times as that of a common silica gel dryer. The dryer is convenient and practical and is free of space occupation. With the natural plant fibers as a moisture absorption carrier, the dryer can be naturally degraded by 100% and belongs to environment-friendly dryers. The plant fiber dryer looks like a thick paper piece and can be cut or chopped into different shapes, can be filled in bottle covers or other containers directly and is an excellent selection for various biological foods, health-caring foods and medicines.

Description

technical field [0001] The invention relates to the technical field of desiccants, in particular to a plant fiber desiccant and a preparation method thereof. Background technique [0002] Desiccants vary in variety and packaging materials depending on their scope of application. From its content: silica gel desiccant, alumina desiccant, natural active desiccant, drying sheet, drying paper, etc., widely used in food, medicine, electronic products, household appliances, handicrafts, instruments, meters, clothing, shoes and hats Control the relative humidity of the environment during the storage and transportation of such products to prevent items from getting damp, mildew or rust. [0003] However, these desiccants have low moisture absorption rate and limited adsorption capacity, and even pollute the environment and the items to be dried, so they cannot meet the market demand. Contents of the invention [0004] In order to overcome the deficiencies in the prior art, the p...
