Aluminum Rigid High Speed Door for Food Industry Application
High Sealing Industrial High Speed Door for Food Processing Plant
& Hygienic Production Environment
Product Overview
The Aluminum Rigid High Speed Door is a high-performance hygienic
industrial high speed door designed for food processing workshops
and clean production environments. Built with smooth aluminum alloy
rigid panels and a high sealing system, this high speed spiral door
effectively prevents dust, moisture, and airborne contamination
while ensuring fast and efficient operation.
It is widely used in food manufacturing plants, beverage production
lines, and packaging workshops, where strict hygiene standards,
easy cleaning, and environmental isolation are required.
Key Features of Food Processing High Speed Door
Aluminum Rigid High Speed Door is designed with a high-performance
sealing system to ensure excellent environmental control in
industrial applications. Its sealing advantages include:
- Multi-layer sealing structure: Combines bottom aluminum profile sealing with flexible strip
seals on the side tracks for full perimeter protection.
- Excellent airtight performance: Effectively prevents dust, airflow, moisture, and external
contaminants from entering the workspace.
- Rigid door panel design: Aluminum alloy structure ensures no deformation during operation,
maintaining stable sealing performance.
- High-frequency operation stability: Even under frequent opening and closing, the sealing system
remains tight and reliable.
- Energy-saving effect: Reduces air exchange, helping maintain indoor temperature
stability and lowering energy consumption.
- Wide industrial suitability: Ideal for cleanrooms, food processing, cold storage,
pharmaceutical, and precision manufacturing environments.
Product Parameters
| Parameter | Description |
| Motor System | The motor drive system adopts a branded motor system, equipped with
an encoder and an emergency manual opening mechanism.
Ensures optimal performance of safety protection devices (such as
infrared sensors) with fast rebound response.
Features strong overload capacity, capable of operating over 1,000
cycles per day in high-frequency applications. Supports
automatic/manual mode switching while ensuring safe operation of
the high-speed door. The control cabinet is installed inside the
workshop, and an external up/down push button is provided outside
the door for convenient access by external personnel. |
| Control System | The rigid high-speed door is equipped with a dedicated control
system and a specialized control box with power options of 0.75 /
1.5 / 2.2 kW.
The control box includes a main power switch, emergency stop
button, manual/automatic mode selector, and manual up/down control
buttons. It allows precise control of the door opening height. |
| End Buffering | End buffering technology effectively protects the reducer and
operating mechanism from rigid impact damage. Speed can be
digitally adjusted according to actual requirements, enabling
full-stroke speed variation (fast–slow–stop), reducing wear on
components and providing outstanding protection for the reduction
mechanism. |
| Door Structure | The door curtain adopts a modular assembly structure, using
aluminum alloy panels specifically designed for industrial doors
with multi-layer sealing strips.
The aluminum alloy hollow panel has a standard width of 90 mm,
thickness of 1.5 mm, and wall thickness of 1.0 mm. The surface is
anodized with organic coloring, available in optional colors.
Panels are sealed with flexible connection strips, offering a
folding life of over one million cycles. The panels do not contact
each other, maintaining long-term flatness and durability. |
| Safety System | Infrared Safety Sensors:
Photoelectric sensors are installed on both sides of the door
frame. When an obstacle is detected beneath the door, it remains
open. If an object passes through during closing, the door reopens
to the preset open position and descends again after a delay once
the area is clear. External infrared devices can be connected to
control fast rebound. Rebound speed and infrared function logic
(single activation or continuous hold-open) can be easily adjusted
via parameters.
Bottom Safety Edge:
When an obstacle is located within the infrared blind zone during
closing, the bottom safety edge triggers an immediate upward
rebound upon contact, effectively protecting people and objects and
preventing accidents. |
| Wind Resistance | Wind resistance up to 32 m/s, compliant with national standard
Grade 12 wind resistance. |
| Transparent Window | High-quality PVC panels with a double-layer structure provide
excellent thermal insulation while maintaining high transparency
and natural lighting. Clear visibility from both sides enhances
aesthetics and overall appearance. (Optional) |
| Sealing Performance | Multiple sealing designs including guide rail sealing, inter-panel
sealing, top sealing, and bottom sealing ensure excellent
airtightness and effective environmental isolation between indoor
and outdoor areas. |
| Thermal Insulation Performance | For an installed door in the closed state (4 × 3 m), the thermal
insulation coefficient is K < 0.6 W/(㎡·K). |
| Manual Operation | In the event of a power failure, the motor brake can be released at
any time, allowing the door to be lifted with the assistance of the
balancing system. This effectively resolves situations where the
door cannot be opened due to power loss or malfunction. |
| Panel Drive System | The door panels are driven by a high-quality, wear-resistant,
high-strength roller chain structure. The synchronized chain drives
the door into a variable-speed roller mechanism for smooth and
efficient operation. |
| Operating Methods | Standard one-touch push button with emergency stop function; manual
opening operation available during power failure. |
