Ice-Free 35°F Operation: Glycol-jacketed and fully insulated vessels maintain consistent, optimal extraction temperatures without the inconsistencies of ice.
Gentle Dual-Impeller Agitation: VFD-controlled, low-shear mixing protects delicate trichomes from streaking and preserves premium melt quality.
Sanitary 316 Stainless Build: Commercial-grade, skid-mounted design featuring zero plastic contact and rapid Clean-in-Place (CIP) capabilities.
High-Throughput Cycles: Achieve full extraction cycles in just 2.5–3 hours using a streamlined, single-operator workflow.
Advanced Filter Cart: An integrated vibratory pre-filter instantly recycles wash water, minimizing water demand and drastically speeding up trichome collection.
MB Solventless ColdWash System
The MB Stainless Solventless ColdWash System is a commercial-grade platform for trichome separation, engineered using proven stainless processing principles from the brewing and food industries.
Designed for efficiency, repeatability, and gentle resin handling, the system minimizes energy use, labor hours, and water consumption while maximizing cannabinoid and terpene preservation without ice.
The True 35°F Advantage
Consistency is paramount for melt quality. Both the wash vessel and integrated cold-water storage tank are fully insulated and glycol-jacketed, including hard-piped process lines. This eliminates fluctuating temperatures and allows true 35°F operation without ice, maintaining optimal, consistent cold-room conditions for top-tier solventless extraction, wash after wash.
Gentle Dual-Impeller Extraction & Recirculation
The system features a low-shear dual-impeller agitation system designed specifically to protect trichome heads, preventing streaking or smearing.
Fully Adjustable Control: Variable Frequency Drive (VFD) controls allow for fully adjustable speed and direction, giving the operator control to optimize care for each specific strain.
Scalable: The adjustable agitation height supports smaller R&D batches while allowing operators to scale production over time.
Integrated Recirculation: An integrated, variable-speed pump recirculates wash water through insulated hard piping, improving extraction efficiency and significantly reducing water usage per batch.
High-Throughput System Timing
Extraction is driven by a gentle, propeller-style agitation system that efficiently separates trichomes while minimizing mechanical stress.
2.5–3 hour full cycle time
Approx. 5% yield from fresh frozen depending on cultivar resin quality and SOP
Single-operator workflow reduces cost per gram
CIP-capable design enables rapid turnaround — 0.5–1 hour between batches
Built for Production — Wash, Rinse, Drain, Repeat
The mechanical design is intentionally simple and overbuilt to maximize reliability and minimize downtime.
Skid-mounted for easy installation and future relocation
Operator platform included for safe ergonomic tank access
A slotted stainless false bottom keeps biomass contained and off filtration bags
Stainless sight glass and level gauge for process monitoring
Industrial control panel with VFD controls for agitator + pump
Full CIP (clean in place)
No plastics contact with material — all 316 stainless sanitary construction
A dedicated cold-room environment is highly recommended for best melt quality.
Filter Cart: Inline Separation + Recirculation
The MB Stainless Filter Cart integrates directly with the system to dramatically speed up filtration and improve water reuse.
Vibratory Pre-Filter: A speed-controlled vibratory auto filter removes residual biomass upstream of the micron bags. Allows water to bypass the bag systems, allowing the bags to collect more rosin before needing to scrape.
Instant Recycle: The majority of wash water is instantly recycled back into the wash vessel, dramatically reducing water demand.
Precision Collection: Uses industry-standard sized micron wash bags.
Ultra-Cold Rinse: A dedicated cold water reserve tank and wash wand ensure final rinsing is performed using the coldest water in the system.

Solventless operators know: Better trichome handling means better melt.
Traditional ice-bucket agitation causes variable temperatures and smears trichomes into plant material, lowering yield and quality. Our dual-impeller low-shear mixing system lifts and tumbles biomass gently, preventing streaking while preserving terpene and cannabinoid integrity. Ice free design keeps the plant material intact for lighter color and higher quality.
No solvents. No ice contamination. No inconsistent agitation.
Just cold, clean trichome separation — at scale — exactly as nature intended.
