Guide to the freeze drying processThe information presented is generic in nature and is the result of research and experience by Labconco personnel and users of freeze drying equipmentIt is our intention to provide a nonbiased review of preparation techniques and freeze drying methods.

In this work we have optimized the design of highly porous granules with a hierarchy of pores from zeolite NaX and CaA powders using a lowcost robust freeze granulation approach and evaluated the granules in terms of CO2 separation from CH4Prior to the freeze granulation process the zeolite suspension characteristics were investigated.

Jan 01 1986nbsp018332In this study vacuum freeze drying using zeolite as an adsorbent of water vapour was applied to food stuffs such as carrot and shrimp for the purpose of improving the drying rate1 Raw samples As raw samples carrot was used because it can be made into various shapes.

SERAIL teamed up with Millennium Energy and Millerail who are the holders of the internationall patents for the ZEODRATION technology.

The drying of aqueous products through Zeodration is an alternative to existing drying processesDuring the zeodration process the product is dried under vacuum at near ambient temperaturesThe evaporated or sublimated water is adsorbed by the Zeolite after completion of the drying cycle the Zeolite is regenerated for the next batch.

The drying operation is very respectful of the product cost efective and eco friendly as it does not require any refrigerant gases.

The preparation of catalytic zeolites can seem like a black artYou might read a paper and marvel at the obvious talent of the researchers the elegance of the science and the tremendous impact of their findings – while at the same time wondering to what extent they genuinely understood what they were doing while they were doing itOf course the researchers themselves are not the problemThey know their area of science very wellThe problem is simply that predicting zeolite function and synthesis is notoriously difficult.

These can be shipped to most parts of Australia and New ZealandFreeze dryers are the revolutionary new way to preserve foodBy removing water the process conserves virtually all the vitamins and nutritional value of the food whilst greatly reducing the end weight and volume of the preserved foodFood can be eaten as is many fruits make.

Zeolites are hydrated alumino173silicate minerals composed of linked alumina AlO 4 and silica SiO 4 tetrahedraCations of group one and two metals – commonly sodium magnesium and potassium – sit in gaps in the structure and balance out the excess negative chargeAs a result the elemental composition of zeolites is.

Zeodration uses the properties of zeolites both as an adsorbent to dehydrate products under vaccum and as a molecular sieve to preserve volatiles flavors and others contained in the product to be dried.
