Performance Comparison of Tray, Bed and Integrated Drying Chamber in Closed Loop Heat Pump Dryer for Bermuda Grass

Drying plays a crucial role in various industries such as food production, agriculture, Siddha, Ayurveda, and medical fields. To achieve controlled drying conditions, heat pump dryer is considered an effective method, allowing for precise control of parameters like temperature, humidity, air velocity. In this study, was designed constructed to investigate the characteristics Bermuda grass (Cynodon dactylon) at different velocities (1.5 m/s, 2.0 2.5 m/s) using three types chambers: fluidized bed dryer, tray combined (a combination tray). The system utilized R134a refrigerant. performance chambers analyzed product. Moisture Removal Rate (MRR) calculated combinations velocity chamber, it observed that achieved higher MRR all compared dryers.
