Problems solved by technology

[0008] However, due to the irritating smell and strong corrosiveness of high-concentration chemical agents for sterilization, if they are exposed to for a long time, they will cause relatively large harm to the operator's health; at the same time, due to the incomplete utilization of chemical agents, the increase in The pressure of subsequent sewage treatment increases the cost
[0009] Therefore, traditional PET bottle cap sterilization methods all have certain deficiencies, and are all unsatisfactory.

Embodiment Construction

[0034] Such as figure 1 As shown, the sterilization device in the present invention includes a sterilization tunnel 8, a hydrogen peroxide spray module 4, a sterile hot air blowing module 5 and an ultraviolet irradiation module 6.

[0035] The sterilization tunnel 8 is linear, with an entrance 8-1 and an exit 8-2 respectively at both ends, and a linear track 3 arranged along its length is installed inside the sterilization tunnel 8 to move the bottle caps 2 to be sterilized from the entrance 8-1 place is delivered to exit 8-2 place. The hydrogen peroxide spray module 4, the sterile hot air blowing module 5 and the ultraviolet irradiation module 6 are sequentially installed on the side of the sterilization tunnel 8 opposite to the front of the opening of the bottle cap 2 along the direction of movement of the bottle cap 2 (ie, the direction from the entrance to the exit) on the wall.

[0036] Such as figure 2 As shown, the hydrogen peroxide spray module 4 is composed of thr...

Abstract

The invention relates to a bottle cap sterilization method and a bottle cap sterilization device. In order to solve the technical problems, the invention provides the bottle cap sterilization method and the bottle cap sterilization device with thorough sterilization, no sterilization dead angle and little residue. The invention adopts the technical scheme that the bottle cap sterilization method is characterized by comprising the following steps of: a, atomizing hydrogen peroxide solution, spraying the atomized hydrogen peroxide solution on a bottle cap to perform sterilization, and ensuring that the acting time of the solution is 5 to 12 seconds; b, blowing sterile hot air to the bottle cap, wherein the temperature of the sterile hot air is 80 to 90 DEG C and the acting time is 3 to 5 seconds; and c, irradiating the bottle cap by adopting ultraviolet with wavelength of 250 to 260 nanometers, and ensuring that the radiation quantity is 333 to 600W.s / m<2>. The method and the device are mainly applied to bottle cap sterilization before filling in the food and beverage industries.

Description

technical field [0001] The invention relates to a bottle cap sterilization method and device, in particular to a PET bottle cap sterilization method and device, which are mainly suitable for bottle cap sterilization before filling in the food and beverage industry. Background technique [0002] At present, the sterilization methods used for PET bottle caps mainly include ultraviolet sterilization, thermal sterilization, and chemical agent sterilization. [0003] Ultraviolet light can change the DNA structure of bacteria and other microorganisms to kill bacteria. In the actual application of PET bottle cap sterilization, the method of directly irradiating the surface of the bottle cap with ultraviolet rays is often used, which has the characteristics of simple process, no chemical residue, and high efficiency. However, this method also has its limitations and deficiencies. On the one hand, with the continuous improvement of the beverage production line speed (even reaching 5...
