Custom Stainless Steel 2-Square-Meter High Efficiency Vacuum Freeze Dryer for Fruits and Flower Petals

With a freeze-drying area of 2 m², this model is a small-scale production-grade unit equipped with independent refrigeration, vacuum, heating, and intelligent control systems. The cold trap temperature can reach -50°C, with a maximum vacuum of ≤2.6 Pa. It can reliably process dozens of kilograms of material per batch, balancing production capacity with flexibility.

Based on the principle of low-temperature sublimation, the material remains in a low-temperature vacuum environment below the eutectic point throughout the entire process, preserving more than 95% of its original activity, nutritional content, and physical form. The moisture content of the final product can be controlled between 1% and 5%, allowing for long-term storage without the need for preservatives.

Suitable for small- to medium-scale production and pilot-scale R&D, it is widely used for freeze-drying high-end snack foods, premium Chinese herbal slices, biological reagents, and functional cosmetic ingredients. It offers a cost-effective solution for drying small batches of high-value-added materials.
