With the combination of pharmaceutical and food products needing to be more shelf-stable than before, acquiring ideal freeze-drying machinery is crucial. Modern freeze driers have much more sophisticated control of temperature, pressure, and moisture which guarantees the quality of the product as well as meeting regulatory standards.
” As sponsored posts go, it was very accurate and not nearly as “salesy” as I’ve seen from other sponsored posts. I’ll share it below, but first I want to answer the question directly.
Allows for up to 10 thermal treatment steps and 12 drying steps, so you can adjust your process for each material with precision. You can control the rate of freezing, the final freeze temperature, and the duration of the freeze cycle.
