Plastic bottle cap rinsing and sterilizing device and method thereof

Abstract

The invention discloses a plastic bottle cap washing sterilization device and a washing sterilization method adopting the plastic bottle cap washing sterilization device. The plastic bottle cap washing sterilization device comprises a primary washing sterilization area, a secondary washing sterilization area and a sterile air jetting area which are arranged in sequence, and a bottle cap passage penetrating through the primary washing sterilization area, the secondary washing sterilization area and the sterile air jetting area, wherein the bottle cap passage positioned in the primary washing sterilization area is spirally arranged from top to bottom, and the bottle cap passage positioned in the secondary washing sterilization area and the sterile air jetting area is linearly arranged; a primary sterilization liquid pipeline, a secondary sterilization liquid pipeline and a sterile air pipeline are provided with spray nozzles with spray openings pointing to the bottle cap passage, and the included angles between the spray opening direction of at least part of the spray nozzles and the bottle cap flowing direction of the bottle cap passage are acute angles. With the adoption of the plastic bottle cap washing sterilization device and the washing sterilization method adopting the plastic bottle cap washing sterilization device, the problems that the bottle cap deforms easily and the washing sterilization effect is poor existing in the bottle cap washing device in the prior art are effectively solved, and the plastic bottle cap washing sterilization device and the washing sterilization method adopting the plastic bottle cap washing sterilization device have the advantages that the cleaning effect is good, the occupied space of the device is small, the bottle cap can not deform, and thus the practical value is very high.

Description

technical field [0001] The invention relates to the field of cleaning technology, in particular to a plastic bottle cap washing and sterilizing device and method thereof, which are mainly suitable for washing and sterilizing plastic bottle caps before filling in the food and beverage industry. Background technique [0002] At present, bottled beverage filling in the food and beverage industry generally uses PET bottled beverage aseptic cold filling technology. Among them, the sterilization effect of packaging materials (PET bottle body and plastic bottle cap) is one of the important parameters of this aseptic cold filling technology. Before aseptic filling of bottled beverages, plastic bottle caps need to be rinsed and sterilized to meet the filling requirements. The bottle cap channel of the traditional plastic bottle cap washing and sterilization device is mainly horizontal and straight. Horizontal linear plastic bottle cap washing and sterilizing devices have to meet th...
