What do you know about Freeze dryer?

If we talk about removing water from a product to keep it for a longer period of time then the so-called word that is used is lyophilization and this is a simple process of removing water or you can say any liquid substance, typically used to preserve perishable materials, to increase the shelf life or make the material more convenient for transport. This procedure simply works on a manner where the water is been removed from the product after freezing it under a vacuum so that the ice can change into solid without changing its form into liquid again.

 Application of the product 

There are so many places where this freeze dryer is used to keep the product out of water which also protect the food or any other product from getting rotten easily. In today’s era so many places are already using it for their benefits as well as for convenience. Also, it is very useful when it comes to the transportation of the product as all the access water comes out from it beforehand. The places where these freeze dryers are used includes: -   

 

• Food Laboratory – Coffee, eggs, Fish, Fruit, and Juices
• Pharmaceutical Industry — Medicines
• Biotechnology
• Dairy Industry – Milk & Curd
• Sugar Cane Industry
• Pet Food
• Taxidermy
• Florals
• Documents Recovery –  Like Titanic ship Sink Documents Preservation
• Research
• Echinacea, Mussels, Shark Cartilage.
• Cheese Yogurts & Meets

FREEZE DRYER FOR LABORATORY, FOOD & PHARMACEUTICAL INDUSTRY:

If we talk about food industry, this method is especially designed for preserving the nutritional quality of food. In simple words the so-called “astronaut food” is a light option (as it is observed that up to 90% of water/solvents are removed from the product), nutritious, and which maintains the flavor and aroma of the product is always very natural and pure. As well as in the research and pharmaceutical industries, it allows the preservation of enzymes, yeasts, and other microorganisms. If we are discussing about the most recent applications then that are: the preservation of flowers and animals, documents and books old or recovered from floods, taxidermy, bone banks, and tissues for implantation. Freeze dryer is used for removing water or organic solvents from a vacuum solution and allowing the water frozen in the material to pass directly from the solid to the gas phase without going through the liquid phase.

How the lyophilization or freeze dryer Procedure works?

In general words, lyophilization is a simple process that consists of removing water (and other liquid items) from a sample, through the process called sublimation, which is the transition from a solid to a gaseous form, without going through a water state.

This process allows preserving the organoleptic characteristics, such as color, brightness, light, odor, texture and flavor, as well as the original shape of the product. So it can be easily restored when hydrated. Thus, as it works at low temperatures, it is also ideal for thermo-sensitive samples, such as enzymes. In addition, it preserves the samples by inhibiting enzymatic and oxidative reactions, which normally happen in the presence of water. It also increases the shelf life of products, which can be stored at room temperature for years.

In principle, to start lyophilization, the sample must be completely frozen. Right after the association of low temperature and pressure, it allows the solvent to be removed by sublimation. As a result, a product with a porous structure is obtained, as well as, free of moisture that can easily be reconstituted by adding water.

Conclusion- in the above article we simply learned the benefits of using a freeze dryer or we can say lyophilization process to keep the product safe and easy to transport. We also understood how the whole procedure works and how the water is been removed from the food product or any other perishable goods.
