Understanding Freeze Drying


Freeze drying is a revolutionary process that removes moisture from food, preserving its taste, texture, and nutrients for extended storage. This method of food preservation offers numerous advantages, such as:

  • Creating lightweight, long-lasting, and delicious freeze-dried foods

  • Foods can be stored for up to 20-25 years

  • A wide variety of food items can be freeze dried, including fruits, vegetables, meats, and entire meals

With commercially freeze dried foods, you can enjoy the highest quality and freshest foods all year round.

Preparation of food prior to freeze drying is a key step to ensure optimal processing. This includes cutting fruits into bite-size pieces, and using parchment paper or silicone mats to prevent food from adhering to freeze dryer trays. By taking these steps, you can look forward to a successful freeze drying experience and delicious preserved food to enjoy in the future.

The Science Behind Freeze Drying

The science behind freeze drying is fascinating and involves the following steps:

  1. Freezing the material

  2. Reducing pressure

  3. Introducing heat, which facilitates the transition of the frozen water in the material to vapor, a process known as sublimation

This technique results in shelf-stable food that typically has a comparable texture and flavor as the fresh product and can last up to 8 years. Freeze drying also has the added benefit of reducing the weight of the food, making it more convenient to transport.

Factors to consider when freezing dry include:

  • Size of the freeze dryer

  • Space requirements

  • Capacity and batch size

  • Noise levels

  • Location

In addition, proper food preparation and pre-freezing, along with vacuum sealing and correct storage, are essential for a successful freeze-drying experience.

Comparing Freeze Drying to Dehydration and Canning

Freeze drying offers better preservation of taste, texture, and nutrients compared to dehydration and canning, but at a higher cost. Freeze drying removes approximately 98-99% of the moisture content, while dehydration only removes about 90-95%. This results in freeze-dried foods having a more pleasing taste, texture, and nutritional content compared to their dehydrated or canned counterparts.

Although freeze drying may be costlier and requires additional time and energy, the benefits of maintaining the flavor, texture, and nutritional content of food more effectively make it a worthwhile investment for those seeking the highest quality preserved food.

Grasping the difference between capacity and batch size is crucial in choosing the right freeze dryer for your needs. While capacity represents the overall size or capability of the system, batch size denotes the number of items or units that are processed or handled together as a group in a single batch. By choosing a freeze dryer with the appropriate capacity and batch size, you can ensure that you are able to process the desired amount of food in an efficient manner.

Size and Space Requirements

Size and space requirements should be considered to ensure the freeze dryer fits in your home and has adequate space for proper operation. The dimensions of Harvest Right freeze dryers, for example, are approximately the size of a small washing machine. When assessing the size and weight of a freeze dryer, it is essential to ensure that the machine is compatible with the available space and not too cumbersome to move.

Additionally, it’s important to consider space requirements for the vacuum pump and room below the freeze dryer for runoff. By taking these factors into account, you can ensure that your home freeze dryer is installed correctly and operates efficiently, providing you with the best possible freeze-dried food.

Noise Levels and Location

Noise levels and location are important factors to consider when purchasing a home freeze dryer, as these machines can be quite loud. The Harvest Right freeze dryer, for example, can reach noise levels between 62 to 67 decibels, even with the quiet motor option installed. To mitigate the effects of noise pollution, it’s recommended to position the freeze dryer away from important and frequently used living areas.

When selecting a location for your home freeze dryer, it is also crucial to ensure convenience and the ability to inspect the machine easily, as well as avoiding any impediments that could disrupt vacuum sealing.
