Microwave Vacuum Lyophilisation Equipment combines the principles of freeze-drying with microwave energy to achieve superior-quality dried products at significantly faster processing speeds than traditional lyophilization. In this process, the product is first frozen and then placed under vacuum conditions where microwave energy is applied to sublimate ice directly into vapor without passing through a liquid phase. This innovative approach dramatically reduces drying cycle times, often by 50–75%, while preserving the color, flavor, aroma, and bioactive components of heat-sensitive materials. Kerone’s microwave vacuum lyophilisation systems are engineered for pharmaceutical, food, nutraceutical, and biotechnology applications where product quality and process efficiency are paramount.

Frequently Asked Questions (FAQ)
Conventional lyophilisation relies on conductive heat transfer from heated shelves through the frozen product, which is inherently slow since heat must travel from the shelf surface inward through the material. Microwave energy instead delivers sublimation energy directly throughout the frozen product's volume, bypassing the conduction bottleneck that limits conventional shelf-drying speed. Because the vacuum environment and controlled microwave power density still allow sublimation to occur below the product's collapse temperature, this acceleration doesn't sacrifice the structural, colour, or bioactive preservation that makes lyophilisation valuable. The result is dramatically shorter primary drying phases, which is typically the longest single stage of a complete freeze-drying cycle, without introducing the quality compromises associated with simply raising shelf temperature to speed up conventional freeze-drying.
Kerone's systems can achieve vacuum levels as low as 0.01 millibar, a depth that matters because effective sublimation, ice converting directly to vapour, depends on maintaining chamber pressure well below the vapour pressure of ice at the product's processing temperature. If vacuum levels aren't deep enough, sublimation slows dramatically or stalls, extending cycle time and risking partial melting that compromises the freeze-dried structure. Achieving and consistently maintaining this depth of vacuum requires high-performance vacuum pumps and tightly sealed chamber construction, which is a meaningful engineering distinction between systems capable of true pharmaceutical-grade lyophilisation and lower-cost equipment that cannot sustain the vacuum integrity needed for consistent, validated freeze-drying results.

Kerone's systems can achieve vacuum levels as low as 0.01 mbar, which is essential for effective sublimation of ice at low temperatures.
Yes, all systems feature PLC-based control panels with recipe management, allowing programmable multi-step cycles with precise control of temperature, vacuum, and microwave power.
Pharmaceutical-grade lyophilisation requires that every product-contact surface be constructed from 316L stainless steel with an electropolished finish, since this material and finish combination resists corrosion, cleans thoroughly without residue retention, and meets the hygiene standards pharmaceutical regulators expect. Buyers should also confirm the system includes comprehensive validation documentation support, automatic condenser defrost for continuous operation without manual intervention, and temperature and moisture sensors providing real-time process monitoring rather than relying solely on end-point testing. These details distinguish purpose-built pharmaceutical lyophilisation equipment from adapted industrial drying systems, and procurement teams should request material certificates and finish specifications in writing rather than accepting general GMP-compliance claims without supporting documentation.
Freeze-drying cycles typically require distinct phases, freezing, primary drying through sublimation, and secondary drying to remove residual bound moisture, each needing different combinations of shelf temperature, vacuum level, and microwave power density. A PLC-based control panel with recipe management allows operators to programme and save these multi-step sequences precisely, so the exact same parameters apply automatically every time a specific product recipe runs, rather than depending on manual adjustment by different operators across shifts. This programmability is particularly valuable for pharmaceutical and nutraceutical manufacturers who need to demonstrate process repeatability as part of regulatory validation, since a documented, automated recipe removes a significant source of batch-to-batch variability that manual control would otherwise introduce.
Pilot-scale lyophilisation systems are sized for formulation development, stability studies, and small production runs, typically handling smaller batch volumes while still offering the same multi-shelf chamber design, microwave integration, and process control found in larger units. Industrial-scale systems extend this same core technology to substantially higher batch volumes needed for commercial production once a formulation and process have been validated at pilot scale. Buyers developing a new pharmaceutical or nutraceutical product should generally start with pilot-scale equipment to establish and validate the optimal freeze-drying recipe before committing capital to industrial-scale equipment, since process parameters developed on a properly designed pilot system transfer more reliably to production scale than parameters developed on equipment that behaves fundamentally differently from the target production system.
