Freeze Drying Containers

Misconceptions In Freeze Drying Glass Vials.

Amorphous materials do not have a eutectic point but they do have a critical point below which the product must be maintained to prevent meltback or collapse during primary and secondary drying.

Both are methods for removing moisture from foods to allow them to last far longer than they normally would before going badDehydration typically removes 95 or so of the moisture within foodsFreeze drying removes as much as 99 of the moistureThis makes freeze drying a more effective solution for extremely long term storage of foods.

Different foods last different lengths of time when freeze driedFruits tend to not last very long becoming less than ideal in as little as 2 yearsThe longest will last 25 years or moreTypically freeze dried foods don’t go bad but they will become less appetizing and powdery as long as they haven’t been contaminated with moisture.

Disadvantages Water required for reconstitution except for simple snacks Slow process — average cycle is 24 hoursSome dislike the dry styrofoam textureNot all foods can be freeze driedAirtight containers are required for longterm storageNo space savings — the food’s cellular structure is mostly retained.

During the primary drying phase the pressure is lowered to the range of a few millibars and enough heat is supplied to the material for the ice to sublimeThe amount of heat necessary can be calculated using the sublimating molecules’ latent heat of sublimationIn this initial drying phase about 95 of the water in the material is sublimatedThis phase may be slow can be several days in the industry because if too much heat is added the material’s structure could be altered.

Freeze Drying Containers Freezedrying can be carried out in a number of containersIn the pharmaceutical and biotech industries the most common format is vials but in the food industry it is more common for product to be dried loose in trays known as bulk.

Freezedrying—technically known as lyophilisation lyophilization or cryodesiccation—is a dehydration process typically used to preserve a perishable material or make the material more convenient for transportFreezedrying works by freezing the material and then reducing the surrounding pressure to allow the frozen water in the material to sublimate directly from the solid phase to the gas phase.

In this phase pressure is controlled through the application of partial vacuumThe vacuum speeds up the sublimation making it useful as a deliberate drying processFurthermore a cold condenser chamber andor condenser plates provide a surfaces for the water vapour to resolidify onThis condenser plays no role in keeping the material frozen rather it prevents water vapor from reaching the vacuum pump which could degrade the pumps performanceCondenser temperatures are typically below −50160°C −58160°F.

Jars – You don’t have to make jam or pickles to take advantage of the art of canning Traditional canning jars are perfect for storing freezedried foodsAll you need to do is make sure they are sanitized and add an oxygen absorber to lock your food up nice and tight for the long haulSome choose to use a vacuum sealer to seal their jars but it8217s vital that all the oxygen is removed when using this method.

Pretreatment includes any method of treating the product prior to freezingThis may include concentrating the product formulation revision iaddition of components to increase stability preserve appearance andor improve processing decreasing a highvaporpressure solvent or increasing the surface areaIn many instances the decision to pretreat a product is based on theoretical knowledge of freezedrying and its requirements or is demanded by cycle time or product quality considerations.
