Product Uses


1. Food Preservation: Freeze drying is used to extend the shelf life of various food products, including fruits, vegetables, meats, and dairy, by removing moisture and preventing microbial growth.

2. Space Food: Freeze-dried foods are commonly used in space exploration due to their lightweight and long shelf life, ensuring astronauts have nutritious meals during missions.

3. Emergency Food: Freeze-dried food is a popular choice for emergency food storage because it remains edible for an extended period and requires minimal storage space.

4. Outdoor Activities: Freeze-dried meals are lightweight and convenient for hikers, campers, and backpackers, providing a source of nutrition while on outdoor adventures.

5. Ready-to-Eat Meals: Freeze-dried ingredients are used in the production of instant soups, noodles, and other ready-to-eat meals that require only hot water for preparation.

6. Dietary Supplements: Some dietary supplements, such as vitamins and probiotics, are freeze-dried to maintain their potency and ensure accurate dosing.

7. Pet Food: Freeze-dried pet food products are available, offering a convenient and nutritious option for pet owners.


Product Operate Guide


The control system of this freeze dryer utilizes an industrial touch panel for user-friendly operation. Each screen is equipped to display a wealth of process data, and it has the capability to store multiple freeze-drying recipes, with each recipe allowing for the configuration of up to 36 segments (standard type).

Our system incorporates an Intelligent Fuzzy Logic algorithm, ensuring precise and stable temperature control throughout the freeze-drying process. Moreover, you have the flexibility to modify temperature parameters as needed during the freeze-drying cycle.

Initiating the freeze-drying process is a seamless operation. The system automatically initiates pre-freezing of the product, starts the vacuum pump, and then proceeds with the freeze-drying process. We have implemented multiple stability measures to ensure the system's consistent and reliable performance.

FAQ


1. Why does the product become lighter after using a food freeze dryer?

The reduction in weight after using a food freeze dryer is due to the removal of water content from the product during the freeze-drying process. This process removes the moisture, leaving behind a lighter, dehydrated product.


2. Why is my freeze-drying time so long?

The extended freeze-drying time can be influenced by several factors. One of the main reasons is the initial moisture content of the food. Foods with higher moisture content will take longer to freeze-dry. Additionally, the performance and capacity of the freeze dryer can also affect drying time. Ensuring that the freeze dryer is operating efficiently and not overloaded can help reduce drying time.


3. Why does my food become fragile after freeze-drying?

The increased fragility of your food after freeze-drying is a result of the removal of water. During the freeze-drying process, moisture is extracted from the food, which can lead to changes in texture and make the product more brittle. This is a normal characteristic of freeze-dried foods.
