Design of an auger thermo-radiation dryer for drying plant-derived pomace

This paper reports the improved model design of an auger thermo-radiation dryer for drying plant-derived pomace under a low-temperature mode (35...80 °C) to resulting moisture content at level 8...13 % solids. The has adjustable speed rotation (3...4 min–1), airflow (0.05...0.09 m/s), and is characterized by uniform distribution heat flux. It equipped with energy-saving two-circuit complex that utilizes secondary energy primary air from 21.1 °C 28.9 °C. use Peltier elements, installed heating technical surface dryer's auger, makes it possible convert thermal into low-voltage supply voltage autonomous supercharger exhaust fans. duration in structure been determined, particular tomato pomace, initial 75 solids, which 107 min. For apple whose starting solids 65 %, 98 comparison, convective (75 solids) 120 minutes. was carried out temperature 60 10...12 Organoleptic evaluation on example confirms effectiveness structural solutions compared technique. results reported this study could create conditions further implementation proposed involving altered technique utilization energy. designed device process preserve quality properties allowing product wide range foodstuffs
