What is a Freeze Dryer, The Advantages of Making the Food Preserving Fresh

To explain it in the simplest terms possible, Freeze Dryer is the process of dehydrating food. To begin with, it has the effect of elongating the shelf life. In addition, it maintains the food’s structure, colour, and flavour while preserving nutrients. These three stages are all you need to know to have a basic understanding of the process of freeze drying.

Step 1: Freeze the Food in an Instant. Before beginning the process of freeze-drying food, the food must be frozen throughout. The technique known as “flash freeze drying” is the most effective way to freeze food, and it’s also the one you should use at home. This is a method used in the food industry in which the temperature of foods is dropped very rapidly to prevent water molecules from congregating and destroying the texture of the food on a cellular level.

Without specialised equipment, Freeze Dryer at home can be challenging. However, you can get a good approximation of the process by thoroughly cleaning the food, spreading it out on a flat so that it does not touch other food, and then freezing it at the coldest temperature possible.

Step 2: is to put the frozen food in a vacuum sealer. Once within the vacuum, the pressure drops, which causes the temperature to cause the ice molecules in the meal to quickly transform into a gas rather than going through the liquid phase first. Having a good freeze dryer at home is necessary to do this task successfully.

Step 3: Prevent any contact between the food and the water. The gaseous state of water vapour is collected within the vacuum, ensuring that it will not be reintroduced to the meal. This reduces the remaining meal options to those high in nutrients, calories, and protein.

The procedure of freezing and drying food.

Lyophilization, also known as Freeze Dryer, removes moisture from raw, frozen goods by using a vacuum system and a process known as sublimation. Raw frozen food is sectioned into pieces of the proper size and then distributed uniformly over trays before being stacked and placed in freezers. Having been sized, the product freezes at an even lower temperature, achieving the ideal stage in which the object’s initial form may be preserved while still retaining its integrity.

After that, the trays are put into a freezer-drying chamber with a refrigeration unit and a door that closes securely. In a process known as sublimation, the ice is removed from the product by the vacuum system of the chamber, and the ice is then converted straight to a vapour without passing through the liquid stage. Because the water is removed from the product while frozen, the cell structure is preserved, and the completed product exhibits a close similarity to its new version. As a result, the item maintains its identity.

Incorporate freeze-dried components into your next application to take advantage of the value brought about by the advantages mentioned above

Whole food nutrients

More individuals are looking for ways to get their daily nourishment from actual, high-quality food sources with labels that are easy to read due to shifting consumer attitudes. Freeze-dried foods may be clean ingredients since they are only an issue processed, meaning that they do not include any components that are synthetic, artificial or excessively processed.

Since freeze-dried fruits and vegetables are the same as their fresh counterparts, manufacturers have the opportunity to make claims about the nutritional worth of their products. The Tru Serv TM programme offered by Van Drunen Farms offers an exclusive method of substantiation that connects our production data and the USDA nutrient database to only our fruit, vegetable, and leafy green ingredients. This method was developed to ensure our customers receive the most accurate information possible.

Freshest

Freeze Dryer maintains more nutrients than conventional drying processes, complementing customers’ need for complete foods. The method retains the original raw material’s colour and form, guaranteeing customers they eat genuine fruits and veggies. Freeze-dried materials taste and smell like raw substances.
