CBD/Hemp Vacuum Drying Oven

Achieve Chem CBD vacuum oven at the center of this lineup was originally built for a broad range of lab and production tasks - powder drying, baking, and disinfection/sterilization of glass containers - with a specific emphasis on materials that don't tolerate direct heat well: substances that are heat sensitive, decompose easily, or oxidize when exposed to air during drying. That's precisely the profile of most CBD distillate, crude oil, and hemp biomass - cannabinoids and terpenes degrade under sustained heat, and extended air exposure at elevated temperature accelerates oxidation and loss of the lighter, more volatile terpene fractions.

Running the drying or solvent-purge cycle under vacuum lowers the temperature needed to evaporate residual solvent and moisture, which means the material spends less time exposed to heat overall. This is why the unit works well as a vacuum oven for CBD distillate purging - the optional nitrogen/inert gas inlet adds a further layer of oxidation control for operators running purge cycles on solvent-laden extract or drying trimmed biomass where oxidative loss is a concern.

Four chamber sizes - 30L, 50L, 90L and 210L - cover the range from small-batch R&D or QC testing up to larger production runs. For processors scaling past pilot volume, the 90L and 210L models function as a large-volume vacuum oven for hemp processing, with shelf heating built to keep heat distribution even across every shelf, not just the ones closest to the element.

Our CBD vacuum drying oven built around one core requirement in cannabinoid and hemp processing: get moisture and residual solvent out without cooking the material or letting it oxidize on the way out. As a CBD vacuum purge oven manufacturer supplying chambers from lab-scale to production volume, we build each unit around that requirement first.

Five-side or shelf heating design (model-dependent) that distributes heat evenly across the chamber under vacuum, avoiding the hot spots that scorch terpene-rich extracts sitting near a single heat source

Vacuum level down to ≤133Pa, letting solvents and moisture evaporate at lower temperatures than atmospheric drying would require - the same principle that protects heat-sensitive, easily decomposable and oxidizable materials

PID temperature control with ±1°C stability and 0.1°C resolution, so a low-temp decarb or purge cycle stays where you set it, not drifting a few degrees in either direction

Built-in inert gas inlet (10mm) for nitrogen or other inert gas purging - relevant wherever oxidation during the drying or purging stage is a concern

Dual-layer tempered glass door for visual monitoring of the material without breaking vacuum to check on it

304 stainless steel chamber paired with a cold-rolled steel housing, plus a KF25 vacuum port for standard pump connections

Chamber volumes from 30L to 210L across four models, covering everything from small-batch runs to larger production volumes

Factory tested under vacuum for 24+ hours before shipment, with a mechanical pressure gauge for direct, reliable vacuum readings

CE & ISO9001 certified · Established 2008 · Free replacement parts for 1 year

Remark: Technical parameters are tested at ambient temperature 20°C, 50%RH, no load, no strong magnetic field and no vibration. Product images are for reference only - please refer to the actual goods received.

Solvent purging on crude oil and distillate. After extraction, residual solvent needs to come out of the oil without pushing the material through a long, high-heat cycle that degrades cannabinoids and drives off the lighter terpenes. Running the purge under vacuum brings the required temperature down, which is the same principle the oven was built around for heat-sensitive, easily decomposable materials generally.

Biomass and trim drying. Hemp flower and trim are exactly the kind of "easily decomposable, oxidizable" material the oven's five-side or shelf heating design is meant to dry evenly - no single hot spot cooking one section of the load while the rest lags behind. It's a common reason processors look for a hemp biomass drying oven supplier that can size the chamber to their harvest volume rather than a fixed one-size unit.

Oxidation-sensitive purge cycles. Where oxidative degradation during drying or purging is a concern, the built-in 10mm inert gas inlet allows nitrogen or another inert gas to be introduced into the chamber, giving operators a way to limit oxygen exposure during the cycle.

Powder and isolate drying. The oven's original design use case - powder drying - extends directly to CBD isolate and crystalline material. As a CBD isolate drying oven, consistent, low-fluctuation temperature control (±1°C) is what matters most for a clean, uniform result across the batch.

QC and small-batch testing. The smaller chamber models (30L/50L) suit lab-scale or QC-batch runs, while the 90L/210L shelf-heating models scale up to larger production volumes without changing the underlying vacuum and temperature control specs.

Whether you're purging solvent from distillate, drying biomass, or finishing isolate to a consistent moisture level, the right CBD/Hemp Vacuum Drying Oven configuration comes down to batch size and cycle requirements. As a custom CBD vacuum oven manufacturer, we size the chamber and heating setup to your process rather than the other way around - send us your typical volume and process step, and we'll help you match it to the VO-16020 through VO-16213 lineup, or answer any spec question directly.
