- Abstract
The article is devoted to the effective mode selection for vacuum honey drying. There were studied an impact of the drying layer thickness and heat flux density on the efficiency of vacuum honey dehydration. Experiments on vacuum drying of honey were carried out at a heat flux density from 2 to 10 kW/m2. The dependences of the relative product mass on the vacuum drying process duration were obtained. If a heat flux density increases, the drying time reduces: when a heat flux density was 2, 4 and 6 kW/m2, the drying time lasted for 270±10, 240±10 and 225±10 min respectively; while at a heat flux density of 8 and 10 kW/m2, the time was 210±10 and 195±10 min, respectively. At the same time, the moisture content of the dehydrated product also changes: an increase in the heat flux density from 2 to 10 kW/m2 leads to the moisture content changes from 4.5 to 5 %. Experimental studies were carried out on vacuum honey drying at a product layer thickness of 5 to 20 mm. It was established that an increase in the layer thickness entails an increase in the drying time, an increase in the moisture content of the dehydrated product, and a decrease in its quality. However, this increases the productivity of the drying unit. Based on the studies, the following effective modes of vacuum honey drying were determined – heat flux density – 4 kW/m2, product layer thickness – 15 mm. It is advisable to dehydrate honey at a residual pressure of 4±0.5 kPa and at a temperature of 40 °C in the drying chamber. Under these conditions, the drying time is 275±10 minutes, and the organoleptic evaluation of the dry product is 34 points out of 40.
