The advent of home freeze dryers has made everything simpler; freeze-dried delicacies are no longer expensive and out of reach. Imagine how exciting it is to easily create delicious freeze-dried food with just the push of a button. Now,Let’s learn about freeze dryers together.
The Role of a Freeze Dryer
Freeze dryers have a wide range of applications, with their main functions including:
Food Preservation
Home freeze dryers can remove moisture from food, greatly extending the shelf life of food while retaining its nutrients. This is something traditional preservation techniques cannot compare with.
Making Healthy Snacks
We can use freeze dryers to make freeze-dried fruits, freeze-dried candies, freeze-dried desserts, or other freeze-dried snacks, achieving the freedom of creating freeze-dried delicacies at home.
Making Pet Food
Home freeze dryers can also produce nutritious pet treats. You can use a freeze dryer to make a variety of pet foods. Compared to traditional pet foods, freeze-dried pet foods are not only healthy but also taste almost the same as the original food, which pets particularly love.(Freeze Dry Maker: A New Trend In The Pet Food Industry)
Freeze-Drying Breast Milk
For many mothers with babies, the advent of freeze dryers has made storing breast milk simpler. Freeze-dried breast milk can be stored at room temperature for years, and the freeze-drying process does not damage the nutrients in breast milk. It can be easily rehydrated when needed.( Freeze-Dried Breast Milk: The New Use For Home Freeze Dryers)
Can Freeze Drying Remove All Moisture?
Freeze dryers can almost remove all moisture from food. General home freeze dryers can remove 99% of moisture from food, and our home freeze dryers can remove more than 99.5% of moisture. Therefore, freeze-dried food can be stored for a long time. If vacuum-sealed bags or airtight jars are used for packaging, freeze-dried food can even be stored for up to 25 years in a cool, dark environment.
Comparison Between Freeze Dryers and Dehydrators
Dehydrators remove most of the moisture from food by circulating hot air, effectively extending the shelf life of food. Because food is treated at high temperatures, its texture and flavor change. Freeze dryers, on the other hand, remove moisture from food in a low-temperature vacuum environment, causing the water in the food to sublimate directly from solid to gas. Since moisture is removed at low temperatures, the texture of the food does not change, and the nutrients are well preserved. From a cost perspective, dehydrators are more economical than freeze dryers, with lower post-use energy consumption. If the household budget is limited, a dehydrator is a better choice. However, if the budget allows, a freeze dryer is the better option in all respects.
Common Questions About Freeze Dryers
How Long Does It Take to Freeze-Dry Food?
The time it takes to freeze-dry food depends on the model of the freeze dryer and factors such as the type, shape, and size of the food. Generally speaking, most foods can complete the freeze-drying process in about 10 to 20 hours.
Will Freeze-Dried Food Spoil?
Freeze-dried food has a very long shelf life under appropriate conditions, but it can still spoil under certain circumstances.
Firstly, let’s understand the ideal storage environment for freeze-dried food. Freeze-dried food needs to be stored in a dry, cool, and sun-protected environment. Additionally, the packaging of freeze-dried food must ensure airtightness. Generally speaking, vacuum-sealed bags or airtight jars are ideal packaging. In such an environment, freeze-dried food can be stored for more than 25 years. On the other hand, if the storage environment is not ideal, such as damaged packaging or exposure to moist air, freeze-dried food can spoil and mold.
Can Home Freeze Dryers Pay for Themselves?
If you have a long-term need for freeze-dried food, using a home freeze dryer can pay for itself. Currently, freeze-dried food sold on the market is very expensive, ranging from tens to hundreds of dollars. In contrast, the price of home freeze dryers ranges from two thousand to six thousand dollars. Therefore, for households that need freeze-dried food in the long term, a home freeze dryer can indeed pay for itself.
Since Freeze Dryers Are So Expensive, Can Food Be Freeze-Dried at Home Without One?
Theoretically, as long as the two conditions of freeze-drying (low temperature and vacuum environment) are met, food can be freeze-dried. A practical approach is to freeze the food in the refrigerator and then place it in an insulated box (leaving a hole for dry ice vapor), then put dry ice in it. After 10 to 20 hours, freeze-dried food can be obtained. However, practical tests have shown that while this method can also freeze-dry food, the final freeze-drying effect is far inferior to using a freeze dryer. Therefore, we do not recommend this freeze-drying method.
