Embodiment 1

[0027] A kind of disinfection and sterilization method of pillow stuffing (millet)

[0028] Take 1000 grams of chitosan with a degree of deacetylation greater than 70%, dissolve it in 10% lactic acid (or take 1000 grams of chitosan lactate, dissolve it in water), and use 0.1Mol / L NaHCO 3 Adjust the pH value of the solution to 3.0~6.5, with a total volume of 100 liters;

[0029] Add the chitosan solution to the millet to be treated in a ratio of 1:20 by weight, stir and mix;

[0030] Send the treated millet into a tunnel microwave heating device (power 20kW), control the heating temperature between 70°C and 95°C, and process for 6 to 8 minutes;

[0031] The processed millet is collected, cooled and filled into pillow cases in a clean environment.

Embodiment 2

[0033] A kind of disinfection and sterilization method of pillow stuffing (silkworm excrement)

[0034] Take 1000 grams of chitosan with a deacetylation degree greater than 70%, dissolve it in 0.1-1.0 Mol / L hydrochloric acid (or take 1000 grams of chitosan hydrochloride, dissolve it in water), and use 0.1Mol / L NaHCO 3 Adjust the pH value of the solution to 4.0~7.0, with a total volume of 50 liters;

[0035] Add the chitosan solution to the silkworm excrement to be treated at a weight ratio of 1:5, stir and mix;

[0036] Send the treated silkworm excrement into a tunnel-type microwave heating device (power 20kW), control the heating temperature between 85°C and 100°C, and process for 7-9 minutes;

[0037] Collect the microwave-treated silkworm excrement, and fill it in a pillow case in a clean environment after cooling.

Embodiment 3

[0039] A kind of disinfection and sterilization method of pillow stuffing (buckwheat husk)

[0040] Get 500 grams of chitosan with a degree of deacetylation greater than 70%, dissolve it in 0.3 Mol / L acetic acid, adjust the pH value of the solution to 3.0~6.4 with 0.1 Mol / L NaOH, and have a total volume of 100 liters;

[0041] Add the chitosan solution to the buckwheat husk to be treated at a weight ratio of 1:10, stir and mix;

[0042] Send the processed buckwheat husks into a tunnel-type microwave heating device (power 20kW), control the heating temperature between 75°C and 90°C, and process for 5 to 7 minutes;

[0043] Collect buckwheat husks and fill them in pillow cases in a clean environment after cooling.

Abstract

The invention relates to the technical field of biology and particularly relates to a chitosan and microwave composite sterilizing method and an application thereof. The method is characterized in that a material is firstly treated with chitosan and then sterilized by microwaves. The method has the advantage that the sterilizing efficiency is remarkably improved under the same microwave power and sterilizing time, is applicable to disinfecting and sterilizing of the medicine and health and food processing and other industries, and is a green and environmentally-friendly sterilizing method. The method applicable to disinfecting and sterilizing of plant-based pillow inner fillers shows the advantages of being high in efficiency and low in energy consumption, and preventing the fillers from generating thermal damage and deterioration, etc.

Description

technical field [0001] The invention belongs to the field of biotechnology and relates to a sterilization method. Background technique [0002] At present, there are many pillows filled with natural plant seeds, roots, stems, leaves, flowers and fruits on the market. These products use the natural volatilization of aromatic substances in plants to calm the nerves and lower blood pressure. , regulating qi and relieving depression, etc. Although the plant series functional health pillow has many advantages, however, the biggest defect of using plants as the filling of the pillow core is that natural plants contain a large number of bacteria and molds. According to the investigation of relevant departments, the content of bacteria and mold in many plant pillow fillings on the market is 4,000-20,000 cfu / g, and some products have the phenomenon of long worms. [0003] Aiming at the problem of sterilization of plant pillow fillings, if ordinary dry heat method or microwave heati...
