FREEZE DRYERS
Wash, press — then freeze-dry to finish the line. Sub-zero drying locks volatiles and drops water activity before you press, so nothing you worked for burns off in the dry. Access Rosin® supplies freeze dryers from Harvest Right and Xiros, sized from home benchtop to industrial.
You washed clean and you press hard — and then a slow, warm air-dry undoes it, taking the volatiles and the color with it. Freeze drying is the fix. It is the last precision step of the line: sub-zero drying that holds the aromatics air-drying burns off and drops water activity before the material ever reaches the press.
Curated and supported by Access Rosin — not a rebadge, a recommendation we stand behind. The same team that designs and builds your presses and wash systems in Lake Forest, California has been pairing the right OEM dryer into shops' lines since 2016. We don't manufacture these units — Harvest Right and Xiros do, and their names and documentation stay on them. What we add is the judgment: we size the dryer to your wash volume, wire it into the line beside our own gear, and pick up the phone when a cycle needs tuning. One team, from the wash vessel to the finished, dried material.
Why Sub-Zero Drying Protects What You Washed For
Locks in the Aroma a Warm Air-Dry Cooks Off
Sublimation at sub-zero temperature pulls water out as vapor without heat — so the volatile aromatics that a warm rack-dry drives off stay in the material, and the flavor survives all the way to the press
Drops Water Activity for Shelf-Stable Material
A tight cycle pulls moisture down low enough that the material stores clean and presses without steam or scorch — press-ready, not half-dried
Turns Days of Racking Into One Unattended Cycle
A programmed cycle runs overnight while you work the next wash, so material comes off dry and on schedule instead of tying up rack space and gambling on room humidity
Watch the Whole Cycle From Your Phone
Monitor drying progress and get alerts on your phone, so you're not standing over the unit or checking it at 2 a.m. — the cycle finishes whether you're in the room or not
Harvest Right — American-Made, Sized for Every Line
The American-made workhorse for freeze-dried output, from a benchtop home unit to a full commercial machine. We help you match the unit to how much you actually wash in a day instead of over-buying capacity you'll never load.
Representative image
Home — X-Large
A Home Pro X-Large bundle: 7 trays and an industrial oil vacuum pump, plus a bag sealer, 50 mylar bags, and 50 oxygen absorbers to store what you dry. The benchtop entry point for small-batch runs.
Scientific — Large
Premier build on US 110V / 60 Hz. Stepped-up capacity and control for producers running multi-batch days who need consistent, documented cycles.
Commercial — HRC100
Handles up to 90 lbs of material per batch — the commercial workhorse for facilities that run a full harvest day in one cycle.
Pharmaceutical — Stainless
Premier build with an industrial oil pump, US 110V / 60 Hz. Stainless-chamber units in three sizes to match your batch.
Xiros — Premium Sublimation Drying
When output volume and cycle control matter most, the Xiros line runs from a compact development unit up to full industrial capacity.
Xiros Mikro V1.12
Benchtop unit with 9 shelves on 12mm trays and roughly 4 kg of ice capacity per 24 hours, built for continuous operation with fully programmable digital controls (~30″ × 30″ × 20″). Designed for water hash and terpene preservation — dial in your process before you scale.
Xiros 2
The industrial Xiros system for large-scale processors documenting every run.
Cold Room — Whole-Room Freezing
Freezer Room Container
A 20-foot container cold room — a walk-in for facilities that pre-freeze and stage material at volume before drying.

Common Questions
Why freeze-dry if I already wash and press?
A warm air-dry drives off the volatile aromatics you washed for and can scorch material. Sub-zero sublimation pulls water out as vapor without heat — so aroma and color survive to the press, and water activity drops low enough to store or press clean.
How long does a freeze-dry cycle take?
A programmed cycle typically runs overnight, unattended — you monitor progress and get alerts on your phone. The benchtop Xiros Mikro handles roughly 4 kg of ice capacity per 24 hours.
What sizes are available?
From a benchtop Home X-Large (7 trays) up to the Commercial HRC100 that dries up to 90 lb per batch, plus stainless Pharmaceutical units, the Xiros line, and a 20-foot cold-room container. We size the unit to your actual wash volume rather than over-buying capacity.
Does Access Rosin manufacture the freeze dryers?
No — Harvest Right and Xiros manufacture them, and their names and documentation stay on the units. Access Rosin curates the right dryer for your line, sizes it to your wash volume, wires it in beside our own gear, and supports it — one team, since 2016 in Lake Forest, California.
Can I finance a freeze dryer?
Yes — financing and leasing are available for qualified buyers, arranged case by case, and Section 179 deductions may apply. Contact our team to talk through options for your purchase.
Picture the end of a wash day: the racks are empty, the room isn't fogged with warm-dry humidity, and the dryer is humming through a cycle you set and walked away from. You come back to material that's dry, aromatic, and ready for the press — with the aroma you washed for still in it, because it never got cooked out on a rack. That's the last step of the line doing its job while you sleep.
