Insights on low-pressure botanical extraction

500L Vacuum Drying Oven with Drawer

A production-scale 18 cu ft vacuum oven with a pull-out drawer and integrated pump that purges and dries large batches of botanical extract at low temperature.

Description

The 500L Vacuum Drying Oven with Drawer brings the same gentle, low-temperature purging and drying to a production floor. A large 18 cu ft chamber on a pull-out drawer holds four heated shelves and an integrated vacuum pump, so big batches of extract are purged of residual solvent and dried without the heat that harms colour, aroma and actives. The drawer design makes loading and unloading heavy trays quick and safe.

How it works

Production drying, still gentle

Trays of extract load into the drawer across four heated shelves, and the integrated pump pulls the large chamber down to a working vacuum of 0.089 MPa. As with the bench unit, the reduced pressure lets residual solvent and moisture evaporate at low temperature, so even large volumes finish cool and clean.

Temperature stays controlled to about 1 °C across the chamber, keeping big batches consistent. The pull-out drawer and 65 lb load capacity make it practical to move serious volume through a production line while protecting the quality of every batch.

Frequently asked questions

Same low-temperature vacuum process, scaled up roughly ten times: an 18 cu ft chamber, four shelves, 65 lb capacity and a pull-out drawer with an integrated pump.

No. Temperature is held stable to about 1 °C across the chamber, so large batches are purged and dried as gently as small ones.

It lets you slide heavy, fully loaded trays in and out easily, which speeds up loading and unloading on a production line.

Yes, the pump is integrated, and the chamber reaches a working vacuum of 0.089 MPa.

4000 W at 208-240 V on a 26 A supply, in a 930 × 1050 × 1990 mm footprint at about 256 kg, with a minimum 10 m² floor area.
