Industrial Freeze Dryer For Food KFD-50 Model
The KFD-50 freeze-drying machine is a dependable piece of equipment that is frequently used to enhance the shelf life and quality of products,in the food processing business.
Brief introduction
Principle
The principle of food freeze-drying is to freeze fresh food containing a large amount of moisture in advance to solidify the moisture, and then sublimate the solidified moisture in a high vacuum.
After sublimation is completed, the remaining adsorbed water is eliminated, and the residual water content of the freeze-dried food is 1-4%.
capacity
The KFD-50 freeze dryer has a loading capacity of 500 kg per batch for fresh raw materials used in heavy products and less than 500 kg per batch for fresh raw materials used in light products.
time
The freeze-drying time mainly depends on the type and thickness of the food, as well as the specific process parameters.
For a 50 square meter freeze dryer, the freeze drying time for common foods is usually between 16-20 hours. The time may be longer if the food is thicker or has a higher moisture content.
Output
The quantity of freeze-dried product would be different as the difference of water content of raw products, approximately 15-40% of the raw product.
