Enzymes also need water to react with food, so dehydrating food will also stop ripening. Freeze-drying significantly reduces the total weight of the food. Most food is largely made up of water (many fruits are more than 80 to 90 percent water, in fact). Removing this water makes the food a lot lighter, which means it's easier to transport. The Frozen in Time F and FR Series has been purpose-designed and developed for food industry production. Available in a range of capacities from 25kg to kg, this high tech series includes a range of advanced programming, recipe creation, storage, data analysis and monitoring features – it’s designed to fit seamlessly into any operation.
However, it is important to understand that dehydrofreezing is not the same as freeze-drying. Freeze-drying is an expensive commercial technique that creates a vacuum while the food is freezing. This technique of food preservation cannot be performed at home. In dehydrofreezing, the foods are partially dried and then, frozen. Freeze Drying is Safe for Documents and Books: “In studies conducted by the Research and Testing Office of the Library of Congress, there was NO evidence found that freeze-drying causes damage of cellulosic and proteinaceous materials (5).” Source: Vacuum freeze-drying, a method used to salvage water-damaged archival and library materials.
The basic process of freeze-drying food was known to the ancient Peruvian Incas of the Andes. Freeze-drying, or lyophilization, is the sublimation (removal) of water content from frozen food. The dehydration occurs under a vacuum and causes the plant or . The Auckland-based company is part of the world-famous Heinz Group and has been producing high-quality vegetables for the food industry since Today, Heinz Wattie's employs more than people and manufactures to the highest quality standard, such as ISO , air-dried, freeze-dried and frozen vegetables.

shade and sun drying, freeze drying. There are three main steps in freeze-drying process. The solution is firstly frozen at extremely low temperature ~−70 to −80°C.
Then the solution is partially dried by reducing the pressure which is known as the initial drying. Finally, in the secondary drying process, the residual water is extracted. The food is spread as a thin layer on a horizontal mesh or solid belt and air passes through or over the material.
In most cases the belt is moving, though in some designs the belt is stationary and the material is transported by scrapers.
Freeze dryers: Freeze-drying is the process of removing water from a product by sublimation or desorption. Freeze dried food is shelf stable – no refrigeration or freezer required for storage. The “freeze” part only comes in during the freeze drying process. When you take the food out of the freeze drying chamber, it’ll be slightly chilled (since there’s ice built up inside the chamber), but should soon warm to room temp.

Freeze drying, also known as lyophilisation or cryodesiccation, is a low temperature dehydration process that involves freezing the product, lowering pressure, then removing the ice by sublimation.
This is in contrast to dehydration by most conventional methods that evaporate water using heat. Freeze drying is a well‐known dehydration process in the food and dairy industry. Compared to other drying techniques such as spray drying or drum drying, freeze drying is an expensive process due to its relatively high investment, operation and maintenance costs.
