Frequently Asked Questions
(FAQ)
Your complete guide to solventless extraction equipment, ice water hash processing, and rosin production.
General Solventless Extraction
Q: What is solventless extraction?
Solventless extraction is a method of separating cannabis resin glands (trichomes) without using chemical solvents like butane or ethanol. Instead, it relies on mechanical separation, ice water agitation, and heat/pressure pressing to produce hash and rosin.
Q: Why choose solventless over solvent-based extraction?
Solventless methods are considered safer, cleaner, and more natural, producing extracts free from residual solvents. They are also easier to set up for compliance in regulated markets and are highly valued for premium-quality products.
Access Rosin Equipment
Q: What type of solventless equipment does Access Rosin manufacture?
We manufacture industrial, food- and pharma-grade systems for solventless cannabis processing, including:
- Rosin Presses (FLUID, FLUID XL, AIR, KWAD, S1/S2/S3)
- Smart Agitator Systems (50, 85, 132, 290 gallon) for ice water hash washing
- Spin Flow Vibration Sieves and false-bottom filter plates
- Chillers, pumps, and iceless water packages
- Consumables like rosin bags, wash bags, bubble bags, and parchment paper
Q: Are Access Rosin systems GMP-ready?
Yes. All equipment is fabricated from stainless steel and food-safe polymers, with UL-certified components and CE compliance, meeting international GMP expectations.
Q: Do you offer both small-batch and industrial systems?
Yes. Our lineup ranges from bench-top rosin presses for boutique operators to multi-hundred-gallon agitation systemsfor enterprise labs.
Rosin Presses
Q: How do rosin presses work?
Rosin presses use heat and pressure to squeeze resin out of cannabis flower or hash. The resin flows into parchment paper pouches, leaving plant material behind.
Q: What makes Access Rosin presses unique?
Our presses feature flow-channel plate design, precision pneumatic or hydraulic pressure control, and compatibility with custom rosin bags and parchment pouches. This ensures smooth operation, higher yields, and cleaner product.
Q: How safe are your presses?
Safety features include two-hand operation, emergency stop buttons, and pressure interlocks. All presses use UL-certified components for compliance.
Q: What size plates do your presses have?
- S1, S2, S3 models: 36” square trapezoid plates (different pressure drivers).
- KWAD models: Four times the surface area for industrial throughput.
Q: How much material can I press at once?
- Flower: Up to 28g per bag.
- Hash: 25–50g per bag.
Q: How much rosin is left behind in a pouch?
Typically 0.5–1.0g, depending on material and press conditions. Our flow-channel parchment pouch system reduces residual loss.
Ice Water Hash Processing (Smart Agitator Systems)
Q: How does ice water extraction work?
Ice water extraction separates trichomes by agitating frozen cannabis material in cold water. Resin heads break off and are filtered through micron bags into hash.
Q: What is a Smart Agitator System?
Our Smart Agitators are industrial-scale stainless steel wash vessels with programmable agitation cycles, recirculation, and temperature/pH control, designed for consistency and yield optimization.
Q: Why use pH adjustment in washing?
Slightly acidic water (pH 4.5–5.5) helps break down plant compounds like chlorophyll, cutin, and pectin, improving resin release and reducing wash times.
Q: What is Hybrid Wash Mode?
Hybrid Wash Mode alternates agitation and recirculation, maximizing resin release while preserving trichome integrity.
Q: Why pre-spray sieve bags with cold water?
It prevents trichomes from sticking to warm mesh, ensuring cleaner separation and higher yields.
Freeze Drying
Q: Why is freeze drying hash important?
Freeze drying removes water without damaging resin heads, preserving terpene content, color, and shelf stability.
Q: What freeze dryers do you recommend?
We recommend pharmaceutical-grade freeze dryers with programmable freeze/dry/hold cycles. Adding mesh layers or tray spacing speeds up drying cycles.
Yields & Efficiency
Q: What yield can I expect from rosin pressing?
Yields vary by material quality:
- Flower: ~15–25% return.
- Hash/ice water resin: ~60–80% return.
Q: How can I maximize yield?
- Use correct micron rosin bags.
- Balance temperature and pressure curves with PID-controlled presses.
- Use cold water washing and properly prepared material.
Maintenance & Cleaning
Q: How often should presses and wash systems be cleaned?
- Presses: Daily wipe-downs and cleaning between batches.
- Agitators: Rinse between washes; perform deep cleaning weekly.
- Sieves and bags: Rinse immediately after use to prevent clogging.
Training & Operation
Q: What skill level is needed to run your systems?
Our systems are operator-friendly. With SOPs, training programs, and commissioning support, teams at any skill level can be trained to run solventless production.
Power & Compliance
Q: What are the power requirements for your equipment?
- Rosin presses: 220V (single or 3-phase depending on model).
- Water extraction systems: 20A, 220V, 3-phase.
- Chillers (10 HP): 40–45A, 220V, 3-phase.
- Ancillary items: Standard 120V/220V outlets.
Q: Are your systems UL or CE certified?
Yes. All systems use UL-certified components, are UL-compliant, and CE-certified for international installations.
