This blog focuses mainly on the concept of freeze drying homework help. Freeze drying is a very old concept. It is a process by which a material is first frozen and then the pressure on the surroundings is reduced so that the water material on its side can easily sublimate and change into a gaseous state. Why so people freeze dry? It is mainly done so that the perishable material is preserved for a longer time period. It is also used while transporting some goods as it makes transportation more convenient. Freeze drying is also known by other names like lyophilizes, cryodesiccation etc.
How did the concept of freeze drying evolve?
The process was first invented by Arsena d’ Arsonval and his assistant Frédéric Bordas in 1906 in Paris. Later on, it was developed by Downey Harris and Shackle in 1911 for preserving rabies virus. By the process of freeze drying, the live rabies virus was preserved which in turn helped in the invention of the anti-rabies vaccine.
The concept of freeze drying homework help would help you to understand how this process is used in the medical science field. This process was also used during World War II to transport Blood serum from Europe to the US. Later on, it was used to preserve quite a number of perishable medicines for a longer time period. Now it is also used in food processing industries, water tank and also for the river – bottom sludge so that hydrocarbons can be analysis.
Uses of freeze drying in different areas
To help you with the concept of freeze drying homework help, we would like to focus on the applications of freeze drying.
Steps used in freeze drying
There are four basis stages that are followed which using the concept of freeze drying homework help:
Different equipment and their uses in freeze drying
There is different equipment that is used for freeze drying process. This part of concept of freeze drying homework help would focus on this equipment. There are mainly three types of freeze dryers – the tray style freeze dryer, the rotatory freeze dryer and the manifold freeze dryer. One of the most important components used in the process of freeze drying is the vacuum that is used to remove the ambient air. The next important thing is the condenser which is use to freeze the material.
The rotary freeze dryer is used to obtain a more uniform freezing by rotation movements. Tray style dryer is generally used in the pharmaceutical purpose. It is generally used to freeze the tissue extracts that can be easily placed on the tray. The manifold freezer is generally used for freezing the liquid substances. These are generally used for perishable goods that would be used in a short time span.
Thus these are the different uses of the techniques used in freeze drying. This was a complete analysis of the concept of freeze drying homework help. As stated before, the concept of freeze drying is nothing new. It was invented way back and scientists are still working to improve the technology.
