A disinfection system and a disinfection control method

Abstract

The invention relates to the technical field of bottle cap disinfection, and provides a disinfection system and a disinfection control method. The disinfection system comprises a disinfector, a liquidinlet pipe connected to the disinfector and a liquid return pipe connected to the disinfector and is characterized in that a regulating mechanism capable of regulating the flow rate of the sterilizing liquid and a pressure detecting mechanism located downstream of the regulating mechanism are arranged on the liquid inlet pipe, a connecting pipe is connected between the liquid inlet pipe and the liquid return pipe, and the connecting pipe is located upstream of the regulating mechanism. The disinfection control method comprises the following steps: S1, detecting the pressure of the disinfection liquid in the inlet pipe during production, and adjusting the flow rate in the inlet pipe to a first set value according to the detected value; S2, when the machine is stopped, detecting the pressure of the disinfectant in the liquid inlet pipe, and adjusting the flow rate in the liquid inlet pipe to a second set value according to the detected value; Wherein the first set value is greater thanthe second set value. The disinfectant can flow in the connecting pipe when the machine is stopped, which can ensure the temperature requirement of the disinfectant, and the disinfection effect can beguaranteed when the production is started again.

Description

technical field [0001] The invention relates to the technical field of bottle cap disinfection, in particular to a disinfection system and a disinfection control method. Background technique [0002] In the aseptic filling process of beverages, the bottle caps need to be sterilized before entering the capping machine. Usually, the disinfectant solution is sprayed and soaked, and the bottle caps are transported under the action of the spray force. In order to make the disinfection effect meet the requirements of commercial sterility, sufficient disinfection time, appropriate concentration of disinfectant solution and temperature of disinfectant solution should be ensured; in order to ensure smooth transportation of bottle caps, appropriate spraying pressure should be ensured. [0003] Existing control systems such as figure 1 As shown, the liquid inlet pipe of the sterilizer 500 is provided with a pneumatic switch valve 100 , a flow meter 200 , a manual control valve 300 and...

AI Technical Summary

Problems solved by technology

At this time, if the disinfectant solution is allowed to continue to spray the bottle cap, the bottle cap will be easily squeezed and deformed under the action of the spray force, resulting in the risk of the cap being jammed.

The disinfectant is usually supplied to the cap sterilizer 500 from the disinfectant preparation tank after being heated by the heat exchanger. If the disinfectant is stopped from spraying and flushing the bottle caps, the liquid supply and heat exchange must be stopped. The temperature of the disinfectant in the pipeline and soaking tank When the equipment starts production again, the temperature of the disinfectant solution may not meet the requirements of the production process, which will affect the disinfection effect
