Our vacuum ovens are purpose-built to perform degassing / purging of light hydrocarbon solvents. Using the technique of cold boiling, the oven applies a gentle heat under reduced pressure conditions to expedite solvent degassing while simultaneously preserving color, aroma, and overall solute quality. We’ve applied our extensive vacuum expertise and industry experience to produce a series of ovens designed exactly for your needs: low consumption, high-throughput, and reliable operation.

CAPACITY AND THROUGHPUT PLANNING
Oven capacity requirements vary widely by the producer. We wanted to create a method to assist in determining the best oven match for your operation, based on a few of the parameters of your extraction and of your desired purge. We based this formula on an expected extraction yield of 25%, with an extract-density of 1 g/in2. Using the following variables, this formula is designed to provide an estimate of your required shelving capacity:
- Size = Extraction Batch Size (lbs)
- Number = Runs per 24h Period
- Purge = Your desired purging duration (hours)
Area Required (ft2) = [(Size) * (Number) * (Purge+1)] / 122
Area Required (in2) = (Size) * (Number) * (Purge+1) * 1.18
