Solution Overview
Problem
Existing plasma sterilization methods for agricultural products face long processing times and risks of secondary pollution, whether performed before or after packaging.
Innovation Solution
A plasma sterilization packaging device that integrates plasma sterilization directly into the packaging process using a conveyor belt system with a plasma generator, roll film adjustment, and sealing devices, allowing for efficient and hygienic packaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plasma sterilization is performed before packaging, then sterilization effect is improved, but processing time increases and secondary pollution occurs
Solution Approach 1:
The patent combines packaging and sterilization operations into a single integrated process. The packaging machine includes a plasma sterilization chamber that sterilizes products during the packaging process itself, eliminating the need for separate sterilization steps before packaging. This merging of operations reduces total processing time while maintaining sterilization effectiveness.
Solution Approach 2:
The system performs rapid plasma sterilization treatment on products immediately before they enter the packaging chamber. This preliminary sterilization action is integrated into the packaging flow, ensuring products are sterilized just in time for packaging without requiring extended pre-treatment time.
2Object-affected harmful factors
If plasma sterilization is performed after packaging, then secondary pollution is avoided, but bactericidal effect is weakened and processing time increases
Solution Approach 1:
The patent integrates the plasma sterilization chamber directly into the packaging machine, allowing sterilization to occur simultaneously with or during the packaging process. This ensures that packaging materials do not interfere with plasma penetration while still achieving effective sterilization, and the sterilized products are then packaged in a controlled environment to prevent secondary pollution.
3Reliability
If multiple cycles of plasma treatment are applied, then sterilization completeness is improved, but total processing time increases
Solution Approach 1:
The system optimizes plasma treatment parameters including power level, gas flow rate, and exposure time to achieve effective sterilization in a single pass or minimal cycles. By adjusting these parameters, the system maintains high sterilization completeness while minimizing processing time to preserve production efficiency.
