WHY IS LYOPHILIZER (FREEZE DRYER) EQUIPMENT SO IMPORTANT?

The Freeze Dryer (Lyophilizer) is an equipment used in many areas, from research laboratories to the food, pharmaceutical and technological industries. This equipment uses the lyophilization process to perform its main function and can have some distinct and suitable types according to the purpose for which they were designed.

But after all, do you know what a freeze dryer is, how it works and its applications?

FREEZE DRYER: EVERYTHING YOU NEED TO KNOW ABOUT THIS EQUIPMENT

The freeze dryer is very useful, because in addition to preserving food better, it allows them to be stored more easily, eliminating the need for very low temperatures and also making them lighter. See a little more about some concepts of lyophilization, how it works and other pertinent information.

WHAT IS LYOPHILIZATION?

Lyophilization is a separation technique that uses sublimation to perform the dehydration of a product. It consists of three steps that include freezing, removing ice and separating the water contained in the sample. In the first stage, all the water in the material is transformed into ice. After that, the sublimation process takes place, where all the ice previously produced is transformed into steam. The third step allows to remove all the water that is still adsorbed to the product, which is transformed into steam. It is a very important process for product maintenance, since after this procedure the material does not need to be kept in a refrigerated environment, making storage easier.

WHAT IS LYOPHILIZER (FREEZE DRYER)?

The lyophilizer is the equipment capable of promoting lyophilization, causing the water to be removed from a product, without it losing its properties. It has a component that makes it possible to allocate the materials that will be submitted to the procedure, in addition to a tool that reduces the pressure around the product to be dried.

HOW DOES THE FREEZE DRYER WORK?

The sample freezing process can be done directly in the lyophilizer or in other equipment that allows this step. In the lyophilizer, the sample is subjected to a pressure drop that occurs with the aid of the device's vacuum pump. 

In order for the ice contained in the material to change state, passing from the solid directly to the vapor, it is necessary that the temperature is high, preventing the solid sample from being transferred to the liquid state.

MAINTENANCE OF FEATURES

The combination of low temperatures and reduced product deterioration make the characteristics of these materials easily maintained through lyophilization. Therefore, nutrients, color, texture and flavor are preserved through this process.

CONCLUSION

The freeze dryer is essential equipment to efficiently dehydrate a sample or product without losing its properties and nutrients. It is widely used in different areas and can have different types that are specific for some purposes. Because it is an item used in so many areas, it is interesting to research which one is the most suitable for your needs. Thus, before purchasing this equipment, look for the one that best satisfies your demand.
