Problems solved by technology

[0005] Food packaging paper needs to use fungicides in the production process. The fungicides currently developed often only act on a specific part of the fungal cells. The unique mechanism of action results in only a very short bactericidal validity period for fungicides with a single point of action. Therefore, Its effective application time is also limited
The current sterilization process is to add a single fungicide at the same adding point. Due to the specificity of a single fungicide, it cannot effectively kill all the various bacterial colonies existing in the production site, the sterilization effect is not obvious, and the amount of fungicide is large. , pathogenic bacteria are prone to develop resistance to

Embodiment 1

[0030] Add RX9100 antibacterial agent in the spray starch preparation tank, the dosage is 2240ml / day, add XD3899 fungicide and RX9100 antibacterial agent in the spray starch storage tank, the dosage of XD3899 is 1500ml / day, and the dosage of RX9100 is 1200ml / day. Add XD3899 fungicide to the spray starch feeding tank, the dosage is 2500ml / day, add in three times, once every 8 hours, add RX9100 fungicide to the cationic starch preparation tank, and add XD3899 fungicide to the cationic starch feeding tank.

[0031] The bactericide adopts the intermittent addition method, and after being put in stably for one week, it is detected five minutes before the addition, and the bacterial content in the spray starch storage tank is 0 ~ 100cfu / mL, which is far less than that of the comparative example, indicating that the bactericidal process of the present invention has Excellent bactericidal and bacteriostatic effect.

Embodiment 2

[0033] Such as figure 1 As shown, add RX9600 fungicide to the outer white water tank of the surface machine, the outer white water tank of the bottom machine, and the outer white water tank of the core machine, and add RX3610 fungicide to the surface layer mixing tank, bottom mixing tank, and core layer mixing tank , add RX9100 antibacterial agent in the spray starch preparation tank, the dosage is 2000ml / day, add XD3899 fungicide and RX9100 antibacterial agent in the spray starch storage tank, the dosage of XD3899 is 1200ml / day, and the dosage of RX9100 is 1000ml / day, Add XD3899 fungicide to the spray starch feed tank, the dosage is 2300ml / day, add in three times, add once every 8 hours, add RX9100 fungicide to the cationic starch preparation tank, add XD3899 fungicide to the cationic starch feed tank, Add RX9100 fungicide when sizing and coating the surface.

[0034] The bactericide adopts the intermittent addition method, and after being put in stably for one week, it is d...

Embodiment 3

[0036] Add RX9100 antibacterial agent in the spray starch preparation tank, the dosage is 2500ml / day, add XD3899 fungicide and RX9100 antibacterial agent in the spray starch storage tank, the dosage of XD3899 is 1600ml / day, and the dosage of RX9100 is 1200ml / day. Add XD3899 fungicide to the spray starch feed tank, the dosage is 2600ml / day, add in three times, once every 8 hours, add RX9100 fungicide to the cationic starch preparation tank, add XD3899 fungicide to the cationic starch feed tank, Add RX9100 antibacterial agent to the surface application-coating starch system.

[0037] The bactericide adopts the intermittent addition method, and after being put in stably for one week, it is detected five minutes before the addition, and the bacterial content in the spray starch storage tank is 0 ~ 100cfu / mL, which is far less than that of the comparative example, indicating that the bactericidal process of the present invention has Excellent bactericidal and bacteriostatic effect....

Abstract

The invention discloses a sterilization process of food packaging paper. The sterilization process comprises the steps that a quick-kill type sterilizing agent and an anti-corrosion type bacteriostatic agent are added into a tank of a starch system; particularly, an RX9100 bacteriostatic agent is added into a spraying starch preparation tank, an XD3899 sterilizing agent and the RX9100 bacteriostatic agent are added into a spraying starch storage tank, and the XD3899 sterilizing agent is added into a spraying starch supply tank. According to the sterilization process, the quick-kill type sterilizing agent and the anti-corrosion type bacteriostatic agent are added into the starch system, so that the sterilization and the bacteriostat can be effectively achieved, the interference of a medicament to the growth of bacteria is increased, the production and the development of the bacteria resistance are delayed, the prevention and control effect is improved to achieve the aim of effective sterilization and bacteriostat, and the pesticide using cost is reduced.

Description

technical field [0001] The invention belongs to the production field of food wrapping paper, in particular to a sterilization process for food wrapping paper. Background technique [0002] There are many types of fungicides used in the production of food packaging paper, which can be divided into inorganic fungicides and organic fungicides according to their molecular structures. [0003] Inorganic fungicides can be divided into oxidizing and reducing types according to their different principles of action. Reducing fungicides have a bactericidal effect due to the reducing properties of substances, such as sulfurous acid and its salts; oxidizing fungicides use their oxidizing ability to play a bactericidal effect. This type of fungicide has a strong bactericidal ability, but not Stable, easy to decompose, and not durable, so it is mostly used to sterilize equipment, instruments and water. Commonly used are hypochlorite, chlorine dioxide, chloramine, ozone, etc. [0004] Or...
