Problems solved by technology

[0002] In order to prolong the shelf life of food, people need to add desiccant in the sealed transportation of food to prevent its quality from being affected by moisture. Most of the existing desiccants are divided into chemical method and physical method. No matter which one is used for a long time, It is prone to agglomeration and leakage, which is not conducive to long-term development

Abstract

The invention relates to a drying agent special for food and a preparation method thereof. The drying agent is composed of, by weight, 45-60 parts of silicon dioxide gel, 10-15 parts of nano silicon dioxide, 6-10 parts of plant fiber, 8-16 parts of zeolite powder, 7-15 parts of active aluminum oxide, 20-30 parts of starch and 15-30 parts of deionized water. The drying agent is easy-to-get in material, the preparation method is simple, and the drying agent is nontoxic, environment-friendly, good in moisture absorbing and locking effect being three times or more than three times of original hydroscopicity, long in service life, stable in chemical property and reusable, thereby lowering cost.

Description

technical field [0001] The invention relates to the field of desiccants, in particular to a special desiccant for food and a preparation method thereof. Background technique [0002] In order to prolong the shelf life of food, people need to add desiccant in the sealed transportation of food to prevent moisture from affecting its quality. Most of the existing desiccants are divided into chemical method and physical method. No matter which one is used, after long-term use, It is prone to agglomeration and leakage, which is not conducive to long-term development. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a special desiccant for food and a preparation method thereof in order to overcome the above deficiencies. [0004] The technical scheme of the present invention includes: a special desiccant for food and a preparation method thereof. The raw material components are composed of the following proportions by weight: 45-60 parts of si...
