Problems solved by technology

[0003] Recently, shell powder and egg shell powder have received great attention from the academic circle due to their natural and non-polluting properties. In the invention patent application document with the patent application number 201210000877.1, a method for preparing egg shell powder is disclosed. Shell powder has a good cleaning effect on food and kitchen products, and is easy to clean without residue, which meets the national food safety standards. The eggshell powder produced by this process needs to directly or indirectly contact the powder to the items that need to be cleaned during use. In fact, the achievement of its decontamination effect mainly depends on the friction between powder particles, the efficiency is relatively low, it is not easy to completely remove tableware stains, and the sterilization effect on vegetables, fruits and meat is very limited; and the application number is 2013

Embodiment 1

[0026] The preparation method of the present embodiment comprises the following steps:

[0027] (1) Carry out pretreatment to raw material eggshell and shell, remove residual impurity;

[0028] (2) crushing the pretreated eggshells and shells to 120 μm;

[0029] (3) Sintering the pulverized shells and eggshells at 510° C. for 4 hours, and cooling to room temperature;

[0030] (4) grinding the sintered and cooled shell powder and egg shell powder;

[0031] (5) adding hot water to the ground shell powder and eggshell powder to form a suspension;

[0032] (6) heating and stirring the suspension at 110° C. for 7 hours;

[0033] (7) The suspension after described heating is filtered, separates out powder and dry, cool, and the infrared spectrum of gained powder shows that calcium carbonate and a small amount of calcium oxide are mainly in this powder, as figure 1 shown;

[0034] (8) Add a total of 65 parts of the various raw materials according to egg powder and shell powder, ...

Abstract

The invention discloses a natural antibacterial adsorption ultrafine powder and its preparation method. The powder is prepared from eggshell powder, shell powder, sodium bicarbonate powder and lipase powder. The preparation method mainly comprises the following steps: preprocessing of shell and eggshell, preparation of ultrafine shell powder and eggshell powder and mixing of shell powder, eggshell powder, sodium bicarbonate powder and lipase powder. Particle size of the antibacterial powder prepared by the method is below 1.5 microns, and distribution frequency is more than 25%. The natural antibacterial adsorption ultrafine powder has a good antibacterial effect. By the method for preparing an antibacterial agent, raw materials are easily available, costs are low, and the environment is protected and there is no pollution.

Description

technical field [0001] The invention relates to a natural antibacterial adsorption ultrafine powder, in particular to a natural antibacterial adsorption ultrafine powder. Background technique [0002] At present, with the rising of food safety issues and the enhancement of public health awareness, people's demand for antibacterial detergents is increasing day by day, and people are paying more and more attention to the safety of detergents. How to completely remove tableware stains, remove pesticide residues in fruits and vegetables, and eliminate meat Food-borne bacteria have become a major research hotspot. The formulations of various detergents with better cleaning effects currently on the market contain some chemical additives more or less. Only ingredients obtained directly from natural substances can ensure Safe and non-irritating, environmentally friendly and non-polluting. [0003] Recently, shell powder and egg shell powder have received great attention from the ac...
