This is a commercial food dryer dehydrator machine. It is used to remove moisture from food items like fruits, vegetables, meat, and herbs using controlled heat and airflow. The goal of using this machine is to preserve food for a long time without using chemicals. It works by blowing hot air over food trays, which slowly removes the water content while keeping the nutrition and taste. People in Bangladesh can use this machine for small businesses, restaurants, or even home food drying. It helps store food safely and reduce wastage.
