Embodiment 1

[0023] Step (1): wet disinfection, bleaching. Put the bamboo chopsticks made of bamboo into the steel wet reaction tank after being ground and finely processed. In the water tank, adjust the power of the ozone generator to produce 10g h of ozone -1 , when the height of the water in the tank is close to the height of the tank, stop water injection and pass ozone. The ozone in the water decomposes slowly by itself, and the bamboo chopsticks are immersed in the water tank for 7 hours. During the whole process, the product of the ozone concentration and time in the water is kept at 100mg·h / L.

[0024] Step (2): dry mildew prevention. Put the bamboo chopsticks soaked in step (1) into a ventilated room to air-dry, then put them into a dry aeration tank, turn on the ozone generator and let the ozone flow in for 0.5 hours. During the whole ozone passing process, the total amount of ozone produced The mass ratio to the total amount of chopsticks is 1:20000, and the chopsticks can be...

Embodiment 2

[0028] Step (1): wet disinfection, bleaching. Put the bamboo chopsticks made of bamboo into the steel wet reaction tank after being ground and finely processed. In the water tank, adjust the power of the ozone generator to produce 20g h of ozone -1 , when the height of the water in the tank is close to the height of the tank, stop water injection and pass ozone. The ozone in the water slowly decomposes by itself, and the bamboo chopsticks are soaked in the water tank for 9 hours. During the whole process, the product of the ozone concentration and time in the water is kept at 180mg·h / L.

[0029] Step (2): dry mildew prevention. Put the bamboo chopsticks soaked in the step (1) into a ventilated room to air-dry, then put into a dry aeration tank, open the ozone generator and let the ozone flow in for about 1 hour. The mass ratio of the amount to the total amount of chopsticks is 1:15000, and the chopsticks can be sold after finishing the ozone process.

[0030] Finally, the ...

Embodiment 3

[0033] Step (1): wet disinfection, bleaching. Put the bamboo chopsticks made of bamboo into the steel wet reaction tank after being ground and finely processed. In the water tank, adjust the power of the ozone generator to produce 50g·h of ozone -1 , when the height of the water in the tank is close to the height of the tank, stop water injection and pass ozone. The ozone in the water slowly decomposes by itself, and the bamboo chopsticks are immersed in the water tank for 6 hours. During the whole process, the product of the ozone concentration and time in the water is kept at 200mg·h / L.

[0034] Step (2): dry mildew prevention. Put the bamboo chopsticks soaked in step (1) into a ventilated room to air-dry, then put them into a dry aeration tank, turn on the ozone generator and let the ozone flow in for 1 hour. During the whole process of passing through the ozone, the total amount of ozone generated The mass ratio to the total amount of chopsticks is 1:15000, and the chop...

Abstract

The invention provides a method for carrying out processing treatment on bamboo chopsticks via ozone. The method comprises the following steps: (1) wet-process disinfection and bleaching: polishing and thinning the bamboo chopsticks made of bamboos, then putting the bamboo chopsticks into a reaction water tank made of steel and injecting the ozone into the water tank together with water flow so as to soak the bamboo chopsticks in the water tank; (2) dry-process mold prevention: carrying out air drying on the soaked bamboo chopsticks in a ventilating room, then putting the bamboo chopsticks into a dry-process aeration tank, opening an ozonator to feed the ozone into the dry-process aeration tank, and tidying and packaging the bamboo chopsticks after an ozone feeding process is finished so as to obtain finished products. The method is safe and reliable. According to the method, no toxic substances caused by the ozone can remain on the chopsticks, and the energy conservation is realized well by virtue of an ozone disinfection method, i.e., good mold-proof, bleaching and disinfecting effects are achieved by only consuming a small amount of electric power without heating.

Description

(1) Technical field [0001] The invention relates to a processing method of bamboo chopsticks, in particular to a method for disinfecting, bleaching and preventing mildew of bamboo chopsticks by utilizing ozone. (2) Background technology [0002] There are two ways to make disposable bamboo chopsticks. The solid state is fumigated and bleached with sulfur. The sulfur dioxide of chopsticks bleached by sulfur gas will seriously exceed the standard, and one of the characteristics of sulfur dioxide is that it will solidify when it is cold. Therefore, when people eat with this kind of chopsticks, when heated, sulfur dioxide gasifies and enters the human respiratory tract, and respiratory diseases such as cough and asthma follow. In addition, sulfur contains heavy metals, such as lead and mercury, which can accumulate in the human body, and long-term accumulation will cause lead poisoning or mercury poisoning. The method of liquid processing chopsticks is bleaching with chlorine ...
