How long does it take to freeze water and juice?
It depends what temperature you try to freeze it at.
What is the difference between a freezer and ice?
A freezer is a appliance that maintains a low enough temperature to freeze whatever is placed inside it, often food. Ice is frozen water, often made in a freezer.
Suppose you have 100kg of fresh strawberries what would be the approximate mass of the strawberries after freeze drying?
That would depend on the water content of the fresh strawberries and the water content of the dried strawberries.
When a membrane is freeze fractured the bilayer splits down the middle between the two layers of phospholipids In the electron micrograph of a freeze-fractured membrane the bumps seen on the fracture?
Integral Proteins.
Can you freeze gas?
Nitrogen can freeze anything and i think it is a frozen gas.
Incas well known invention?
Quote from the Related Link: "The basic process of freeze-drying food was known to the ancient Peruvian Incas of the Andes. Freeze-drying, or lyophilization, is the sublimation/removal of water content from frozen food." See the Related Link.

Is lyophilization a method of dry heat sterilization?
If we limit our discussion to the enveloped viruses HIV, HCV and HBV, then lyophilization is a sterilization method as explained in my recent article [Cell Tissue Bank (2011) 12:99-104]. Desiccation of the lipid envelops inactivates these viruses.
What is lyophilisation?
Freeze-drying (also known as lyophilization or cryodesiccation) is a dehydration process typically used to preserve a perishable material or make the material more convenient for transport. Freeze-drying works by freezing the material and then reducing the surrounding pressure and adding enough heat to allow the frozen water in the material to sublime directly from the solid phase to gas.
What two of state are involved in freeze drying?
The two changes of state involved in freeze drying are melting and freezing.
Is lyophilization a sterilization process?
yesOnly If the process is followed by standards and protocol.The lyophilization process generally includes the following steps:Dissolving the drug and excipients in a suitable solvent, generally water for injection (WFI).Sterilizing the bulk solution by passing it through a 0.22 micron bacteria-retentive filter.Filling into individual sterile containers and partially stoppering the containers under aseptic conditions.Transporting the partially stoppered containers to the lyophilizer and loading into the chamber under aseptic conditions.Freezing the solution by placing the partially stoppered containers on cooled shelves in a freeze-drying chamber or pre-freezing in another chamber.Applying a vacuum to the chamber and heating the shelves in order to evaporate the water from the frozen state.Complete stoppering of the vials usually by hydraulic or screw rod stoppering mechanisms installed in the lyophilizers.Source..

What is lyphilization?
Lyophilization is a process where water is removed from a product by freezing it and then subjecting it to very low pressure, causing the ice to sublimate directly from solid to vapor without passing through the liquid state. This process helps to preserve the product by reducing the moisture content and extending its shelf life.
Is freeze drying a physical change or chemical?
Freeze-drying is a chemical change because it changes the actual composition of the object by removing water.
What are freeze dryers used for?
Freeze drying is a method of dehydrating a perishable product to enable long term storage or easier transportation. One well known application is freeze drying coffee.
Is freeze-drying a chemical or physical change?
yes
How does freeze drying clothes work and what are the benefits of using this method for drying clothing?
Freeze drying clothes involves freezing them at a very low temperature and then removing the ice by sublimation, which turns it directly into vapor. This method helps preserve the fabric and prevents shrinkage or damage that can occur with traditional drying methods. The benefits of freeze drying clothes include faster drying times, reduced energy consumption, and maintaining the quality and shape of the clothing.
Is freeze drying a healthy method of food preservation?
Freeze drying is a healthy method of food preservation because it retains most of the nutrients in the food and does not require the use of preservatives.
