Description
The Dual-Frame “A-Frame” Blender is a cGMP tumble blender engineered for high-capacity powder and granule mixing with superior stability and precision. Its dual-support frame design ensures smooth rotation and consistent blending, even with large vessels. Built to accommodate a range of vessel types, including V-Shells, Offset Cones, Double Cones, or Bins, this blender delivers reliable performance and uniform results. Designed for easy cleaning and maintenance, it provides a robust, sanitary solution for large-scale powder processing applications.
Direct Drive Rotation
The vessel is directly driven by a TEFC electric gearmotor with an integrated fail-safe brake, providing controlled and reliable rotation. A solid, precision-machined shaft supports the vessel and is carried by three industrial-duty bearings to ensure smooth, effortless rotation underload. Integrated encoders provide continuous position feedback for accurate vessel alignment throughout the operation.
A-Frame
Industry standard A-frame design. fabricated from 304 stainless steel and polished to a uniform brushed finish. All external welds are as laid, pit free and chemically cleaned. All motors, gearboxes, and electrical enclosures remain fully enclosed within the footprint of the blender’s frame. The A-frame maintains a clean exterior and minimizes exposure to the production environment.
Barrel Coupling Alignment
The vessel is aligned using a precision barrel coupling to ensure perfect alignment with the frame. This design accommodates slight floor unevenness, preventing binding and reducing stress on the vessel that could lead to cracking. By maintaining accurate alignment, the coupling ensures smooth, reliable rotation and extends the service life of the system.
cGMP Design
The blender is engineered and assembled to the highest level of cGMP compliance. All surfaces and components are designed for ease of cleaning, with smooth transitions and minimal crevices to prevent product accumulation. This thoughtful design supports hygienic operation, simplifies washdown, and helps maintain a safe, contamination-free production environment.
Optional – Drum Loading Module
The drum loading module is designed to safely handle drums for fully contained loading of the blender. Two stainless steel pneumatic cylinders raise and lock the drum into position over a remotely actuated butterfly valve. The blender then rotates 180° while the valve opens, allowing controlled material discharge into the vessel. Once the drum is empty, the blender automatically returns to the home position. The module is fully removable to support easy cleaning, changeover, and maintenance.
Optional – Manway Interlock
The manway is interlocked with blender motion using a trapped interlock key system. The key must be inserted and secured before rotation is permitted, ensuring the manway is properly closed and preventing product loss during operation.
Operator Controls
Controls all equipment movements with automated sequencing. At minimum, the following user interfaces will be provided: Power On/Off, Emergency Stops, Reset, Start/Stop Blend, Manual Set Blend Time, Manual Set Blend RPM, Jog Forward/Reverse.

Optional – 21 CFR Part 11 Compliancy
The PLC system furnished 21CFR Part 11 compliant – data logging, archiving & auditing data stored onto a locally stored file for Ethernet download. Tiered Security based on pre-determined user groups and privileges.
Stack Light with Audible Alarm
A stack light with an integrated audible alarm can be added to provide clear visual and sound-based status indication of lift operation, fault conditions, or safety interlocks. This enhances operator awareness and improves overall system visibility within the processing area.
Safety Light Curtain
A safety light curtain can be installed to create a non-contact protective barrier that prevents access to hazardous areas. If the beam field is interrupted during operation, the system will automatically stop motion to protect the operator from moving equipment.
Safety Laser Scanner
A floor-mounted safety laser scanner can be incorporated to provide three programmable safety zones, enabling warnings, controlled slow-down, or a full system emergency stop based on intrusion level. Multiple scanners can also be linked together to create a wider, continuous protective field around the lift.
