Abstract

The invention discloses a drying agent and a preparation method thereof. The drying agent is prepared from the following raw materials in parts by weight: 35 to 50 parts of montmorillonite, 10 to 20 parts of traditional Chinese medicine mixtures, 5 to 12 parts of plant starch, 3 to 5 parts of active carbon, 8 to 10 parts of hydrochloric acid and a proper amount of water. The drying agent can be prepared sequentially through the steps of montmorillonite purification, traditional Chinese medicine extraction, mixing pelleting, drying and cooling and the like. The drying agent uses the montmorillonite as the major raw materials and solves the problems of low adsorption speed and limited adsorption capability in the prior art. The drying agent has the advantages that the ingredient raw materials can be degraded to hundred percent; non-toxicity and green and environment-friendly effects are achieved; the price is low; the cost is reduced; the pressure on the environment is reduced; the drying agent is suitable for being popularized.

Description

technical field [0001] The invention belongs to the technical field of desiccant, and in particular relates to a desiccant and a preparation method thereof. Background technique [0002] A desiccant is a substance that can remove part of the moisture in a wet substance. Such as calcium sulfate and calcium chloride, etc., are dried by combining with water to form hydrates; physical desiccants, such as silica gel and activated alumina, are dried by physically adsorbing water. Moisture control is closely related to product yield. For food, under proper temperature and humidity, bacteria and mold in food will multiply at an alarming rate, causing food to rot, causing dampness and discoloration. Change. Electronic products can also cause metal oxidation due to high humidity, resulting in defects. The use of desiccant is to avoid the occurrence of defective products caused by excess water. [0003] At present, there are many types of desiccants, each with their own characteris...
