Embodiment 1

[0012] A preparation method of a special desiccant for food, mainly comprising the following steps:

[0013] A. Pulverize the montmorillonite and put it in an oven to dry until the water content is ≤1%, to obtain a montmorillonite desiccant. The temperature is kept at 400°C for 2 hours;

[0014] B. Calcining limestone with high CaO content to obtain calcium oxide desiccant, the temperature is set to 1250°C;

[0015] C. Mix the montmorillonite desiccant and calcium oxide desiccant, add appropriate amount of activated carbon particles and silica gel particles and stir;

[0016] D. Fill and extrude the mixture in step C into the rayon-coated film, and sterilize for 6 minutes with an ultraviolet device to obtain the final product.

Embodiment 2

[0018] A preparation method of a special desiccant for food, mainly comprising the following steps:

[0019] A. Pulverize the montmorillonite and put it in an oven for drying until the water content is ≤1%, to obtain a montmorillonite desiccant. The temperature is kept at 300°C for 3 hours;

[0020] B. Calcining limestone with high CaO content to obtain calcium oxide desiccant, the temperature is set to 1300°C;

[0021] C. Mix the montmorillonite desiccant and calcium oxide desiccant, add appropriate amount of activated carbon particles and silica gel particles and stir;

[0022] D. Fill and extrude the mixture in step C into the rayon-coated film, and sterilize it with an ultraviolet light instrument for 8 minutes to obtain the final product.

Embodiment 3

[0024] A preparation method of a special desiccant for food, mainly comprising the following steps:

[0025] A. Pulverize the montmorillonite and put it in an oven to dry until the water content is ≤1% to obtain a montmorillonite desiccant. The temperature is kept at 500°C for 1 hour;

[0026] B. Calcining limestone with high CaO content to obtain calcium oxide desiccant, the temperature is set to 1300°C;

[0027] C. Mix the montmorillonite desiccant and calcium oxide desiccant, add appropriate amount of activated carbon particles and silica gel particles and stir;

[0028] D. Fill and extrude the mixture in step C into the rayon-coated film, and sterilize for 6 minutes with an ultraviolet device to obtain the final product.

Abstract

The invention discloses a preparation method of a drying agent special for foods. The preparation method mainly comprises the following steps of A, preparing a montmorillonite drying agent; B, preparing a calcium oxide drying agent; C, performing mixing and stirring; and D, performing stuffing and disinfection. The drying agent is simple in processing method, low in processing cost, high in adsorptive capacity, good in absorption properties, free from resurgence, good in heat resistance, free from toxins, harmless, green and safe, and peculiar smell is effectively removed; man-made fiber coating films are used, so that the drying agent can be better protected; and the man-made fiber coating films can degrade and are good in air permeability, so that the leakage problem can be solved, and the food health can be better guaranteed.

Description

technical field [0001] The invention relates to the field of food additives, in particular to a preparation method of a food-specific desiccant. Background technique [0002] Desiccant is a substance with hygroscopic function, and its principle is to adsorb water molecules in its own structure through physical adsorption. The desiccant has the function of absorbing moisture and is harmless to the human body. It is a common material for food additives. The desiccant is made of adsorbents and adhesives combined with other auxiliary materials, which can effectively improve the drying efficiency. The existing desiccants contain certain chemical agents, which are harmful to the human body, and will have peculiar smell after long-term use. Contents of the invention [0003] The object of the present invention is to provide a preparation method of a food-specific desiccant to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve th...
