50㎡ middle Vacuum Freeze Dryer

Traditional drying processes cannot achieve stable large-scale industrial production while ensuring high-quality nutrition and long shelf life of food.

The 50㎡ medium-sized vacuum freeze dryer uses low-temperature vacuum sublimation drying technology to directly remove moisture at -40℃, achieving drying without damaging the food structure.

It can help companies achieve:

✔ Maximum retention of nutrients (approximately 97%)

✔ Stable original shape, flavor, and color of food

✔ Long shelf life of products

✔ Support for 50㎡ industrial-grade batch production needs

The 50㎡ medium-sized vacuum freeze dryer employs a built-in alternating collector structure and a -40℃ low-temperature vacuum sublimation drying process. While ensuring the stability of food nutrition, structure, and flavor, it achieves industrial-scale production capacity (maximum single batch capacity of approximately 600kg, depending on the material). The equipment features rapid vacuuming and a stable refrigeration and condensation system, effectively shortening the production cycle and reducing unit energy consumption. It is suitable for long-term stable production of coffee, fruits and vegetables, seafood, and high-end foods. This model has been applied in export-grade food processing scenarios, balancing product quality consistency and long-term operational reliability, making it suitable for food companies with clear production capacity plans and international market demands.

Retains nutrients: Freeze-dried food retains up to 97% of its nutrients, including vitamins, minerals, and antioxidants.

Long shelf life: Freeze-drying removes the potential for bacterial growth, so freeze-dried food can last for years.

Maintains flavor and texture: Freeze-drying preserves the original shape, flavor, and texture of food.

Sustainable: Freeze-drying reduces food waste and transportation and storage costs.

The 50㎡ medium-sized vacuum freeze dryer is primarily designed for medium to large-sized food processing enterprises, suitable for applications with specific requirements for product quality stability, shelf life, and large-scale production.

1. Ready-to-eat and Instant Food Production: Suitable for the industrial freeze-drying of products such as instant coffee, instant tea, and ready-to-eat soup mixes. The low-temperature vacuum sublimation process maintains the original flavor and solubility, meeting the consistency requirements of ready-to-eat products.

2. Deep Processing of Fruits, Vegetables, and Agricultural Products: Widely used in the production of freeze-dried fruits, freeze-dried vegetables, and fruit powders. It extends the shelf life while maintaining color, structure, and nutritional components, making it suitable for export-oriented agricultural product processing enterprises.

3. Meat and Seafood Processing: Suitable for processing high-protein foods such as freeze-dried meat and freeze-dried seafood. It allows for long-term preservation without damaging the product's structure, reducing reliance on the cold chain and facilitating cross-border transportation and storage.

4. High-end Functional Foods: Suitable for freeze-drying of bird's nest, probiotic cultures, protein powder, and functional ingredients. For products requiring high temperature and vacuum stability, it enables safe and controllable industrial production.

5. Pet Food Freeze-Drying Applications: Suitable for the production of freeze-dried pet food and pet nutritional supplements. It effectively preserves protein structure and nutrients, meeting the quality and safety requirements of pet food.
