Batch Pasteurization System

The Macrowave™ RF Batch Pasteurization System, introduced by Radio Frequency Company (RFC) — the world’s largest producer of RF pasteurization equipment — is designed to meet the needs of research labs, institutions, and manufacturers handling lower-volume batches of products. It enables efficient, validated pasteurization of up to about 250 pounds per hour in a compact setup.

The Macrowave™ RF Batch Pasteurization System by Radio Frequency Company is a compact, air-cooled unit — roughly the size of a kitchen refrigerator — that delivers rapid, uniform pasteurization for low-throughput products. It features fiber optic temperature monitoring, a large RF applicator (36″ × 32″), and programmable treatment cycles with recipe storage.

Key Features of the Batch Pasteurization System

• Fiber Optic Temperature Monitoring
  Temperature probes inserted directly into the product feed data into a closed-loop control system. This ensures precise control by reducing RF output as temperatures near the target, preventing overshoot during hold time. Both “time-to-temperature” and “hold-time” are fully programmable and storable via PLC recipes.
• Large RF Applicator Area
  The applicator measures 36″ (width) by 32″ (depth), accommodating various container sizes and batch types.
• Compact, Air-Cooled Design
  The system fits in the footprint of a kitchen refrigerator and requires no external cooling infrastructure.
• Heated Applicator Compartment
  A thermostatically controlled ambient heating system prevents radiational cooling of product surfaces and avoids condensation during treatment.
• Programmable Cycles with Recipe Selection
  Easily configure treatment parameters via the Human Interface Module (HMI): adjust temperature, “time-to-temperature,” and hold duration to optimize microbial reduction while preserving product quality. 

Operational Details

• Support & Compliance
  RFC offers in-house testing facilities at their Millis, MA factory, along with full spare parts inventory and experienced field service technicians. The system is OSHA‑, FCC‑, EU‑compliant, and UL‑certified.
