Pass Box is an indispensable solution in food processing factories to ensure the safe and clean delivery of raw materials and finished products. This article will update the latest Pass Box price list, helping businesses easily choose the right equipment for their needs and budget, while understanding the factors that affect the price.
1. Overview of Pass Box in Food Processing Plants
What is a Pass Box?
A Pass Box (also known as a Pass-Through Box) is an intermediate device in a cleanroom system that allows the transfer of items between two areas of different cleanliness levels without affecting the pressure, cleanliness, or environmental conditions of each area.
In food processing plants, Pass Boxes are often installed at material-finished goods transfer points or between rooms with different hygiene requirements.
Main purposes:
- Minimize cross-contamination risks from item movement.
- Optimize operational processes by reducing the need to frequently open cleanroom doors.
- Meet the requirements of HACCP, ISO 14644, ISO 22000 standards.
Basic Operating Principle
The Pass Box works on the principle of air isolation between two environments:
- Interlock doors allow only one door to be opened at a time, preventing air from one room from entering the other.
- Some Pass Boxes are equipped with UV lamps to sterilize item surfaces before transfer.
- High-end Pass Boxes have HEPA filters to create a clean airflow inside the transfer chamber.
Transfer process:
- Staff place items into the Pass Box from the sending room → Close the door.
- The system ensures safety locks before allowing the receiving side door to open.
- Staff in the receiving room open the other door and retrieve the items.
Role in Preventing Cross-Contamination & Meeting Standards
In food factories, the Pass Box serves as a critical control point for safe production:
- Prevents cross-contamination between raw material areas and processing/packaging areas.
- Reduces environmental contamination risk from direct door opening.
- Meets HACCP requirements: Assists in managing hazards and critical control points (CCP).
- Complies with ISO 14644: Limits changes in pressure and cleanliness between rooms.
- Aligns with ISO 22000: Supports a comprehensive food safety management system.
2. Types of Pass Box Used in the Food Industry
Manual Pass Box - Features and Applications
Features:
- Fully manual operation, doors opened/closed by hand.
- Mechanical interlock ensures only one door is open at any given time.
- No electronic components or motors, making the unit durable and easy to maintain.
- Common materials: 304 stainless steel or 316 stainless steel (corrosion-resistant, easy to clean).
Applications:
- Suitable for areas with low transfer frequency.
- For transferring dry, packaged items in food factories.
- Locations without UV sterilization or electronic control requirements.
Semi-Automatic Pass Box - Mechanism and Advantages
Mechanism:
- Combines electronic interlock with semi-automatic controls.
- Some models have UV lamps that automatically turn on when the door is closed to sterilize surfaces.
- Doors can be opened smoothly with assistance from mechanical aids or electromagnets.
Advantages:
- Reduces manual effort during operation.
- Improves safety compared to manual Pass Boxes.
- Enhances sterilization efficiency in high-risk contamination areas.
Applications:
- Processing-packaging areas requiring surface sterilization.
- Food factories with moderate transfer frequency.
Automatic Pass Box - Features and Recommended Use Cases
Features:
- Fully automated operation with electronic control panel.
- Equipped with UV lamps, HEPA filters, door sensors, and alarms for incorrect operation.
- Can log activities or connect to cleanroom monitoring systems.
Recommended use cases:
- High hygiene requirement zones (e.g., instant food packaging, dairy processing, fresh product handling).
- Continuous production lines needing high-speed, hygienic transfers.
- Factories certified to HACCP, ISO 14644, ISO 22000.
