Batch pasteurizer and sterilizer APEX

cannabisnot specifiedradio frequency

Overview
Microbial pathogens, specifically mold and yeast, are a common cause of post‑harvest quality loss and regulatory non‑compliance for cannabis flower. Stalam's APEX series provides a batch, post‑harvest radio frequency (RF) treatment that is organic‑compatible, non‑ionizing and chemical‑free, delivering volumetric heating that inactivates target microorganisms while preserving sensory and chemical attributes.

How it works
Operating at 27.12 MHz, the RF field excites water molecules in the natural moisture of the cannabis; the field polarity changes ~27 million times per second, producing intermolecular friction and uniform volumetric heating. Treatment temperatures typically range 60°C–90°C. The RF effect combines synergistic thermal exposure with cell membrane electroporation to inactivate microbes without ionizing radiation.

Performance and efficacy
The dual‑action RF treatment has been shown to reduce total yeast and mold count (TYMC) to <10,000 cfu/g in a single cycle, even from starting counts up to ~150,000 cfu/g. Typical batch sizes of 2–8 kg are processed in approximately 15 minutes, providing consistent reduction regardless of product density, size or thickness.

Benefits

• Comprehensive volumetric treatment: RF penetrates uniformly through the product mass; 2–8 kg batches treated in ~15 minutes.
• Chemical‑free and non‑ionizing process: Organic‑compatible, non‑irradiating and non‑oxidizing; reduces TYMC to <10,000 cfu/g in one cycle from high initial counts.
• Quality preservation: Preserves cannabinoids, potency, moisture and sensory attributes (texture, color, aroma) with no reported decarboxylation.
