Fruits and Vegetables Dryer

Fruits and vegetables are essential components of the human diet, providing vital nutrients, fiber, and antioxidants. However, these products are highly perishable due to their high moisture content. To extend shelf life and reduce post-harvest losses, drying is one of the oldest and most effective preservation techniques. A Fruits and Vegetables Dryer is a device or system designed to remove moisture content from fresh produce through controlled heating and airflow. Objective of Drying The primary goal of drying fruits and vegetables is to: Reduce water activity to prevent microbial growth. Extend the storage life of produce. Decrease weight and volume for easier transportation and packaging. Preserve nutritional value, taste, and texture (to the extent possible). Add value to agricultural products by transforming them into shelf-stable commodities. Working Principle The working principle of a fruits and vegetables dryer involves heat and mass transfer. Heat is applied to the produce to increase the vapor pressure of the moisture inside the cells, and air is used to carry the evaporated moisture away from the product surface.
