Hot Air Dryer for Food Industry
Hot Air Dryer for Food Industry
A HotAir Dryer in the food industry is an energy-efficient drying system
designed to remove moisture from food products using controlled hot air
circulation. These dryers help preserve food by reducing water activity,
inhibiting microbial growth, and extending shelf life. Available in batch or
continuous modes, hot air dryers are essential for processing fruits,
vegetables, herbs, meat, fish, spices, and more. Modern systems feature
temperature and humidity controls, ensuring uniform drying while preserving
flavor, color, and nutritional value.
Frequently Asked Questions (FAQs)
