Product Operate Guide

1. Split design with pre-freezing in the pre-cooling chamber and drying in the drying chamber, enhancing drying efficiency significantly.

2. High-precision temperature control of the shelves ensures uniform drying results.

3. Adjustable and controllable shelf temperatures for process development and optimization.

4. Separate drying chamber and cold trap, providing strong water-capturing capability and shorter drying times.

5. Touchscreen operation with a dedicated freeze-drying PLC controller, displaying drying curves.

6. Square-shaped trays are resistant to deformation, easy to handle, and simple to clean.

7. Optional inflation valve for introducing inert gases during drying.


1. The freeze-drying time for small food freeze dryers is often long. Are there any ways to speed it up?

The length of freeze-drying time is typically related to the moisture content of the food and the performance of the machine. To expedite the freeze-drying process, you can take the following measures: Firstly, choose foods with lower moisture content, as this will reduce the freeze-drying time. Secondly, ensure that the refrigeration and vacuum systems of the small food freeze dryer are operating properly to provide sufficient cooling and vacuum. Lastly, evenly distribute the food on the trays to ensure uniform freeze-drying. If you require faster freeze-drying, consider upgrading to a larger-capacity or higher-performance freeze dryer.

2. How can I clean and maintain a small food freeze dryer?

Maintaining cleanliness and conducting regular maintenance are crucial for preserving the performance and hygiene of a small food freeze dryer. You can follow these steps for cleaning and maintenance:

· Periodically clean the freeze-drying chamber, trays, and cold trap to remove residue and dirt.

· Use appropriate cleaning agents and disinfectants for cleaning, and make sure all components are thoroughly dry before reassembling.

· Additionally, regularly inspect and replace consumables like filter cartridges and vacuum pump oil in the refrigeration system to ensure the equipment operates correctly.

3. What types of food can I freeze dry in a small food freeze dryer?

Small food freeze dryers are suitable for freeze-drying a variety of foods, including fruits, vegetables, meats, seafood, dairy products, pastries, and more. You can choose different ingredients based on your needs to create various food products. Before freeze-drying, ensure that the ingredients are appropriately prepared and sliced to achieve the best freeze-drying results.
