Modular Programmable Biomass Dryer System With HEPA Filtered Air Rack Design

This highly adaptable, modular Biomass Dryer System is the essential development and pilot-scale platform for botanical processing research centers, contract toll processors, and small-batch artisan herbalists. Whether handling a 5-kilogram test batch of exquisitely dried cannabi flower or a 200-kilogram run of adaptogenic herbs, this single-sku platform uses a plug-and-play rack design with fully programmable temperature, humidity, airflow, and lighting profiles. It brings the precision of a pharmaceutical stability chamber into an industrial-grade dryer, allowing a formulator or processor to develop, validate, and scale a perfect drying recipe that locks in color, potency, and aroma, providing an unparalleled bridge between a tabletop lab oven and a full production tunnel dryer.

Developing a premium dried herb product—whether a particularly vibrant hem p flower or a medicinally optimized herb lot—requires an iterative, precise, and highly recorded drying regimen. Standard production dryers are too inflexible and too large to risk on a speculative trial. A researcher or contract manufacturer is therefore stuck performing R&D on a small laboratory oven, which behaves completely differently from a large forced-air unit, making the results non-transferable. The alternative is to risk an entire production lot on a “best guess” recipe, which either yields sub-optimally dried, hazy biomass or a heat-degraded batch worth a fraction of its potential market value. There is a critical need for an intermediate, scalable platform that can replicate production-scale air dynamics in a small footprint and allow the user to create and lock a proprietary, product-differentiating drying SOP.

Our Modular Dryer fills this gap with a pilot-scale unit that faithfully simulates production drying conditions. The fully programmable PLC allows the formulator to design complex, multi-step drying cycles: a cool, high-humidity "sweat" phase; a ramping airflow phase; a finish phase with UV-C surface sterilization, all on a time-triggered data-logged curve. The modular rack system means small tray quantities can be run economically. Crucially, the airflow dynamics from the horizontal cross-flow fans mimic the air movement of our large-scale continuous belt systems, making the recipe a scientifically valid scale-up model. For a contract manufacturer, the system’s ability to store unlimited "Brand X Hem p A" vs "Brand Y Mushroom" recipes and generate a full batch report turns pilot drying into a billable, high-value service, not just a pre-processing step.

• Cannabi R&D: Developing and locking-in the ideal drying recipe for a new genetic cultivar’s unique floral structure.

• Botanical Contract Manufacturing: Running client-supplied raw herbs through a validated, billable, quality-assay development batch.

• Artisan Herbalist Production: Small-batch drying of premium tisane herbs, preserving maximal color and volatile oils.

• Nutraceutical Pilot: Drying pilot batches of fermented or probiotic-inoculated plant material for stability testing.

The user simply loads pre-weighed trays onto the rack, selects a stored recipe or creates a new multi-step program on the HMI, and presses start. The PLC takes command, managing the cooling compressor, heater elements, and humidifier to hold the target air setpoint with PID precision. The variable speed fan ensures the air velocity across the bed mimics the scaled-up process intent. The onboard precision balance continuously monitors the weight of a single master tray, allowing the system to automatically advance to the next drying step or end the cycle once a target weight loss percentage is achieved. The system then generates a complete PDF batch report for documentation.

Define the minimum batch size you need for statistically valid analytical testing; this sets the tray capacity. Do not compromise on the control variables: the system must be capable of managing not just temperature, but also active humidity injection and fan speed profiling. Ensure your supplier’s larger production systems mirror the cross-flow horizontal air dynamics of this modular unit, otherwise the scale-up route is broken. An essential option for a GMP-compliant pilot facility is a validated temperature and humidity sensor suite, with a pre-calibrated, replaceable sensor module that can be sent for external verification without taking the machine offline.

1. Q: Can I dry cannabi in this unit without it smelling up my entire facility?
   A: Absolutely. The system is completely sealed and uses a HEPA-filtered, closed-loop air path with an activated carbon odor-control module on the exhaust. No volatile terpenes or aromatic compounds are vented to the workspace, allowing discreet in-house R&D operation.

2. Q: How do we know the recipe will scale to a large production belt dryer?
   A: We provide a documented scale-up protocol. Because our modular dryer uses the same horizontal cross-flow aerodynamics and air-saturation logic as our large belt and tray dryers, the same temperature/ΔP/air velocity parameters directly transfer with only a belt loading density correction factor.

3. Q: Is the software 21 CFR Part 11 compliant for our GMP batch records?
   A: Yes, the software module includes secure user access and an un-editable electronic batch record. The process curve, any alarms, and the final weight loss data form a complete electronic batch history for your quality release.

4. Q: Can I process high-sugar herbal extracts that are very sticky?
   A: We offer a non-stick, food-grade silicone mesh liner kit for the trays and a gentle, pulsing airflow cycle that inhibits skinning-over. The adjustable fan speed is key, as high velocity on a sticky puree would cause flaking, while low velocity with the correct humidity gently cures it.
