The freezer is an item that is commercially used to store and preserve food.These devices are even used for medical purposes.The freezer room is very portable and can be saved anytime and anywhere.They can have different shapes and sizes, and these freezer rooms are completely different from what you see in your home.These devices are expensive and take up a lot of space.The equipment is used even in bars and restaurants.Products for home purposes are cheaper than laboratories for several research and development projects.They are more or less similar to the refrigerator in the room, the only difference is that the temperature of both items is different.The temperature of the freezer room is usually from-1 to -5.In addition to the temperature range, another important factor is that the equipment needs to be energy-efficient, as this is an important part of setting up the freezer.If we discuss freeze-drying, it is a dehydration process that is usually used to preserve delicate materials so that they are more suitable for transportation.The freeze dryer usually works by freezing the material and then reducing the pressure so that the frozen material is sublimated from the solid state to the gas phase.This process was developed somewhere before and after World War II with the aim of preserving the blood of battlefield damage and not even destroying the organic properties of the plasma.Since then, the process has been used to preserve or process various types of products.These applications are not limited to food processing, but are used for the production of synthetic skin, the repair of damaged documents and the processing of medicines.The whole process is carried out in four stages.e.Pre-treatment, freezing, primary drying and secondary drying.Freeze-dried foods include frozen foods, which then basically remove moisture from the food and then seal the food in close storage.These foods can be kept and stored for a long time, and can be eaten in a minimum amount of preparation, and you will notice that they taste similar to the original.Although they were originally used to preserve blood on the battlefield, they are now even used to store and preserve food materials.There are some foods that are perfect for freezing and drying.Coffee, chicken slices, beef, lobster all frozendried.All types of fruits and vegetables can even be frozen and dried, and items such as olives and nuts can also be treated by freezing and drying.
