WebThe lab scale microwave vacuum dryer offers a freeze drying option. The minimum vacuum level is 0.5mbar. A 2kW/2450MHz vacuum dryer is generating microwave power in the range from 200 to 2000W. The IR camera can measure from -50 to 200°C. Also a fibre optical sensor is available to measure temperatures inside the product volume. Web11 mrt. 2024 · Processing times are 20 min to 2 hours per batch, also much lower than the 24 h to 36 h for freeze-drying. Materials needed are just a used household microwave, a used household fridge compressor, some tubing and cabling, and an Arduino microcontroller. Probably together still below 100 EUR.
