Pharmatech MB015 Laboratory Drum-Type Powder and Granule Blender

Overview

The Pharmatech MB015 is a GMP-compliant, laboratory-scale drum-type blender engineered for precise, reproducible dry powder and granule blending in pharmaceutical, nutraceutical, food, and cosmetic R&D and pilot-scale manufacturing. It operates on the principle of tumbling motion—rotating the entire mixing vessel (drum or cone) about a fixed axis—to induce convective and diffusive mixing without mechanical agitation. This low-shear, gravity-driven mechanism preserves particle integrity, minimizes attrition, and ensures content uniformity across small-batch formulations (0.1–5 L). Designed to meet stringent regulatory expectations, the MB015 integrates mechanical robustness, process transparency, and operational traceability—core requirements for early-phase formulation development, blend uniformity studies (per USP ), and tech transfer to commercial-scale equipment.

Key Features

• GMP-validated stainless steel construction (304 SS frame and contact parts), fully welded and electropolished where applicable
• Adjustable rotational speed range: 5–30 rpm, digitally controlled via integrated HMI for precise kinetic profiling
• Tool-free, ergonomic quick-change drum coupling system compatible with multiple geometries: cylindrical (25° tilt), square-conical IBC, V-shaped, Y-shaped, double-cone, and custom-profile drums
• Interlocked safety door with IP65-rated enclosure (IEC 60529), ensuring operator protection and dust resistance during operation
• Vertical auto-stop function halts rotation when the drum reaches its upright loading/unloading position—reducing manual handling risk
• Modular mobility: base-mountable on optional 304 SS trolleys with integrated drum storage, brushed finish, and polished welds
• Standard 5.7-inch color touchscreen HMI with intuitive parameter entry (time, speed, direction), real-time status display, and fault diagnostics

Sample Compatibility & Compliance

The MB015 accommodates free-flowing and moderately cohesive powders and granules across a wide density spectrum (tested up to 1.0 g/mL bulk density; max load: 3.3 kg in 5 L drum). Its design conforms to EU GMP Annex 15 (Qualification of Equipment), ISO 14644-1 (cleanroom compatibility), and FDA guidance on process validation for solid dosage forms. Optional IQ/OQ/DQ documentation packages—including FAT protocols—are available to support regulatory submissions. The unit carries CE marking per Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU. For hazardous environments, ATEX-certified variants (II 2G Ex db IIB T4 Gb) can be supplied upon request.

Software & Data Management

The standard HMI logs all critical process parameters (start/stop timestamps, speed setpoint, actual RPM, duration) with timestamped event history. An integrated thermal printer provides immediate hard-copy output of each batch record—including operator ID, batch ID, and deviation flags—with archival stability exceeding 25 years under ambient storage. For full 21 CFR Part 11 compliance, the optional PLC-based control system adds electronic signatures, audit trail functionality, role-based access control, and encrypted data export (CSV/Excel). While the MB015 does not include NIR monitoring (a feature reserved for the BV-series), its architecture supports third-party sensor integration via analog/digital I/O ports for future scalability.

Applications

• Pre-formulation blending trials and excipient compatibility screening
• Blend uniformity assessment for API-excipient systems prior to compression or encapsulation
• Small-batch production of clinical trial materials (Phase I–II)
• Process optimization studies: residence time distribution, scale-up correlation, and shear sensitivity evaluation
• Validation of mixing endpoints using offline assays (e.g., HPLC, UV-Vis) correlated with MB015 operational parameters
• Training platform for GMP-compliant blending SOP development and operator qualification

FAQ

What is the maximum recommended fill level for the 5 L drum?
For optimal mixing efficiency and content uniformity, the drum should be loaded between 30% and 70% of total volume—i.e., 1.5–3.5 L for the 5 L configuration. Maximum mass load is 3.3 kg at 1.0 g/mL bulk density.
Can the MB015 be validated for use in regulated environments?
Yes. Full qualification documentation (DQ/IQ/OQ) and Factory Acceptance Testing (FAT) reports are available as optional deliverables. Installation includes calibration certificates for speed and timer functions.
Is the HMI interface configurable for multi-language operation?
The standard firmware supports English only; however, localized UI overlays can be implemented via PLC upgrade for sites requiring bilingual operator interfaces.
Does the MB015 support continuous monitoring of torque or power draw?
No. Torque sensing (5 Nm nominal) is used internally for overload protection but is not exposed as a real-time data stream. For energy-based mixing analysis, external power analyzers may be connected via the motor’s terminal block.
Are replacement drums supplied with material certification?
All standard drums are manufactured from 316L stainless steel and supplied with EN 10204 3.1 material test certificates, including chemical composition and mechanical property verification.
