Freeze-drying makes it possible to freeze products gently. They are subsequently dried in a vacuum. After the product is frozen, the pressure is controlled so it remains under the sublimation pressure. Slightly heating the frozen material while maintaining the same pressure causes the water to sublimate. The steam that is liberated freezes on the subcooled condenser. JUMO offers you temperature and pressure sensors for this process to provide optimum control of the freeze-drying process, for example in combination with the JUMO IMAGO 500 process controller. The JUMO LOGOSCREEN nt paperless recorder further increases reliability and safety by accurately recording your measurement values.
