“…The drying profiles of the rhizomes during drying in the Polydryer with the operation of the heater were converted into drying models by fitting using linear logarithmic equations of Lewis, Henderson and Pabis, and Page models as summarized in Table 1 [34][35][36][37][38][39].…”

In this study, a superabsorbent polymer dryer (Polydryer) used to obtain dried medicinal plant materials (Simplicia) was incorporated with a heater to enhance the drying rate. In general, the Polydryer was constructed using a cabinet containing polymer hydrogel (polygel), a gas-fueled heater, and a drying cabinet. A polygel synthesized from acrylic acid and cassava starch was utilized to reduce the moisture content in the drying air prior to entering the heater. The drying performance of the Polydryer with and without heater operation was investigated. The results showed that the drying in the Polydryer with heater operation required 18–26 h to attain a final moisture content of 8.8–10%, significantly faster than the Polydryer without heater employment (95–119 h). In addition, the drying of medicinal plants in the modified Polydryer followed the Page thin-drying model. The Simplicia products also showed a slightly lighter color, with no significant structural differences than those obtained without heat implementation. Overall, this drying machine is a time-effective and energy-efficient system that can be applied in pharmaceutical and agricultural industries on a large scale.

“…Drying or dehydration was carried out in a laboratory hot air oven available at the National Institute of Technology Mizoram. 50-60 °C is the optimum drying air temperature, and 10-14% (wb) is the safe moisture level, at which ginger quality can be retained [17]. The temperature in the oven was set at 60 °C and initially ran for half an hour with no load condition to get the steady-state condition.…”

Hot air drying of ginger (Zingiber Officinale) samples (10 mm × 10 mm × 5 mm) having an initial moisture content of 84.89% (wet basis) were carried out at 60°C. Effect of treatment prior to drying was studied at different concentrations of calcium chloride (CaCl 2 ) of 3, 3.5, 4, and 4.5 Mol per liter and compared with the samples dried without pretreatment. Also, process intermittency was applied with a pulse ratio of 1.5 by keeping the sample in vacuum or open atmosphere. During intermittent drying, the products were dried in hot air dryer for 40 min, followed by either vacuum drying or open-air drying at ambient conditions for 20 min. It was observed that calcium chloride with higher concentrations had a significant effect on the moisture extraction rate. Open-air intermittency exhibited better rehydration ability and lowest shrinkage ratio, which facilitated a higher drying rate during the falling rate period.
