Abstract

  The study was conducted to calculate, design, fabricate and test a bee pollen heat pump raking device assisted dryer with a yield of 10 kg/batch. The aim of mixing material is to increase the contact of pollen with drying air, thus, increasing heat exchange, drying efficiency and drying rate. Besides, it reduces energy consumption and increases product uniformity. Experimental planning was carried out to determine the influence of operating parameters of the drier on the quality of the dried bee pollen. A set of mathematical equations represents the dependence of electrical energy consumption of the drying process, vitamin C content in the dried pollen and product recovery rate on drying temperature and the raking cycle was determined. The result showed that, at the drying temperature of 38.4⁰C and raking cycle of 10 minutes, the drier operates at optimal working condition with the minimum electrical energy consumption Ar_min = 0.96 kWh/kg, maximum vitamin C content C_max = 72.11% (256.7 mg/kg) and maximum product recovery rate M_max = 75.46%. 

Keywords: Pollen Heat Pump; Bee Pollen; Vitamin C
