The drying process is as follows: Firstly, the internal moisture of food has been frozen in the low-temperature environment. Secondly, in drying step, the ice inside previous raw material will directly be converted into steam evaporation during a near-vacuum environment. Finally, the internal moisture of food will dramatically decrease. The whole dewatering process is under a lower temperature environment than that of traditional dryer.

Frequently Asked Questions (FAQ)
A freeze dryer is an industrial system that removes moisture from materials using controlled heat and airflow.
It operates by circulating hot air or transferring heat to evaporate moisture from products efficiently.
It ensures faster drying, energy efficiency, and product uniformity.
Industries like food, agriculture, pharmaceutical, and chemical commonly use these dryers.
Yes, Kerone designs every system according to specific industry and process needs.
Yes, precise temperature control ensures safe drying for sensitive materials.
Kerone’s designs optimize heat recovery and minimize energy consumption.
Regular inspection, cleaning, and calibration ensure optimal performance and longer lifespan.
Yes, this is the primary reason pharmaceutical and biological products are freeze dried; the absence of heat and liquid water during lyophilization prevents the degradation reactions that would reduce potency in thermally dried or liquid-stored products.
Properly lyophilized products reconstitute rapidly in water due to the highly porous, sponge-like structure created by sublimation; reconstitution times of seconds to minutes are achievable for pharmaceutical vials.
Conventional heat-based drying exposes a product to elevated temperatures and, in many cases, a liquid water phase during evaporation, both of which can trigger degradation reactions in heat- or hydrolysis-sensitive compounds such as certain proteins, enzymes, and biological actives. Freeze drying avoids both of these stressors: the product remains frozen and solid during the critical primary drying stage, and moisture leaves as vapor through sublimation rather than passing through a liquid state. This combination of low temperature and avoidance of liquid water is precisely why freeze drying is the preferred method for pharmaceutical biologics, certain food actives, and other products where potency or structural integrity must be preserved through the drying process.
AISI 304 stainless steel offers strong corrosion resistance and is widely accepted across food and pharmaceutical regulatory frameworks for direct product contact, which matters significantly in freeze drying applications given the sensitive, often high-value nature of the materials being processed â biological actives, pharmaceutical intermediates, and premium food products. The chamber, trays, and vapor condenser are all surfaces that contact either the product directly or the water vapor removed from it, so material consistency across all these components reduces contamination risk and simplifies cleaning validation. This material choice also supports the repeated cleaning and sterilization cycles that pharmaceutical-grade freeze drying operations typically require between batches.
The vacuum system is what enables sublimation to occur at low temperature by reducing chamber pressure below the point where ice can exist as a stable solid at typical primary drying temperatures. A high-performance vacuum system maintains the deep vacuum needed consistently throughout the drying cycle, which directly affects how quickly sublimation proceeds â weaker or unstable vacuum performance extends cycle time and can risk partial product melting if pressure rises above the critical point for the product's formulation. Kerone pairs the vacuum system with the refrigeration system's condenser capacity, since the condenser must continuously capture sublimated vapor to maintain the vacuum level the process requires throughout the full cycle.
Many freeze-dried products, particularly pharmaceutical and certain food actives, require packaging under vacuum or inert gas immediately after drying to prevent moisture reabsorption or oxidative degradation before the product reaches its final sealed container. Kerone's freeze dryers support a wide range of product containers with provision for sealing under vacuum or inert gas directly as part of the drying cycle, which avoids the quality risk of exposing a freshly dried, highly hygroscopic product to ambient air during a separate packaging step. Buyers whose products are sensitive to moisture reabsorption or oxygen exposure should specify this sealing requirement early, since it affects chamber and tray configuration.
Sublimation during freeze drying leaves behind a highly porous, sponge-like internal structure where ice crystals once occupied space, and this porosity is precisely what allows water to rapidly re-penetrate the dried material during reconstitution. Properly executed freeze drying typically achieves reconstitution times of seconds to minutes for pharmaceutical vials, and slow or incomplete reconstitution can indicate that the original drying cycle didn't achieve adequate porosity, possibly due to incomplete sublimation or structural collapse during the process. This is why reconstitution performance is often used as a downstream quality check that reflects how well the freeze drying cycle itself was executed, beyond just confirming the product reached its target moisture level.
