Bulk freeze drying is an advanced dehydration process used for food and non-food applications. It’s a cost-effective alternative to other dehydration methods, such as moisture pump, moisture vacuum, and spray dehydration. It’s also known as batch drying or simultaneous evacuation and sublimation. In this blog post, you will learn the benefits of bulk freeze drying, how it works and why it’s beneficial over other dehydration methods. Keep reading to discover everything you need to know about the benefits of bulk freeze drying.
What is Bulk Freeze Drying?
Bulk freeze drying is a method of food dehydration that uses sublimation to remove water followed by an evacuation cycle to remove the remaining water vapor. Bulk freeze drying is a more advanced dehydration method compared to other traditional methods like spray drying. It works by removing water from the food product and then removing the remaining water vapor using a vacuum. The freeze drying process occurs in two steps: sublimation and desorption. Sublimation is the change from a solid state to a gaseous state without passing through an intermediate liquid phase. Desorption is the change from a gaseous state to a condensed state. In freeze drying, sublimation and desorption occur simultaneously.
How Does Bulk Freeze Drying Work?
Bulk freeze drying is the process of removing water from a product and the surrounding environment in a controlled environment. During the freeze drying process, the food product is placed in a controlled environment and is frozen. While frozen, water inside the product freezes, forming ice crystals. The ice crystals reduce in size as they lose their water content. During the freeze drying phase, the surrounding environment is isolated from the product. The environment is usually a vacuum. The freezing process and the isolation from the environment creates a frozen water vapor. As the ice crystals melt, the water vapor condenses into droplets, which are then removed from the environment.
6 Benefits of Bulk Freeze Drying
Here are 6 benefits of bulk freeze drying that you should know - Cost-Effective Frozen Environment - When a company uses bulk freeze drying, water is removed from the product without passing through an intermediate liquid phase. When compared to other dehydration methods, bulk freeze drying is less expensive because it doesn’t require the use of heat. Increased Product Life Span - Frozen water droplets inside the product are removed, which means the end product has a longer shelf life. Improved Texture and Taste - Bulk freeze drying also removes most of the product’s moisture, which results in a drier and more stable end product. When moisture content is reduced, the product’s texture improves. .
Additionally, bulk freeze drying doesn’t require high temperatures, which means the quality of the product’s taste remains the same. Purified Air and Reduced Contamination - During the freeze drying process, air is removed from the environment to protect the product from contamination. The air is then filtered and re-circulated.
