“…The cost of drying for drying 500 kg of turmeric rhizomes was calculated as $33 per batch and $ 0.06 per kg. The total operating costs increased with the increase of hot air temperature, drum speed, air velocity and biomass (as fuel) resulted that higher energy expenditure was required for higher drying levels (Perazzini et al, 2021).…”

Turmeric is a challenging crop to dry because of its heat sensitive volatile content and browning characteristics. In this study, a pilot scale biomass fired rotary drum dryer was developed for drying turmeric rhizomes. The drying experiments were conducted at 50, 60, and 70 C air temperatures at an air velocity of 2 and 3 m/s and the drum speeds of 6 and 9 rpm. The turmeric rhizomes dried at a faster rate at the operating conditions of 70 C air temperature, 3 m/s air velocity and 9 rpm drum rotational speed. Among the evaluated thin layer drying models, Page model comparatively gave higher R 2 values (0.998), lower sum of square error (0.001), and root mean square error (0.01) values. The effective moisture diffusivity of turmeric in the rotary dryer ranged from 0.33 to 0.5 Â 10 À10 m 2 s À1 . The calculated activation energy of turmeric rhizomes was 19,338 kJ/kg mol À1 . The higher curcumin, oleoresin, starch, and color values such as lightness, redness, and yellowness value of 4.92%, 16.5%, 58.09%, and 59.87, 28.43, and 74.21, respectively, was observed at 50 C, 9 rpm drum rotational speed and 3 m/s air velocity. The results indicated that the color of turmeric could be retained by drying at 50 C. Practical ApplicationsThe present scenario, turmeric has been considered as an important crop against COVID-19 due to its antiviral properties and also food applications such as natural coloring agent and flavor enhancer. The unit operations involved in turmeric processing is washing, boiling, drying, polishing, and size reduction. The amount of curcumin content presents in turmeric decides its value. Drying is the timeconsuming process compared to other unit operations and has an impact over the quality parameters of turmeric. Sun drying is the main traditional drying method normally practiced by the farmers for bulk drying of turmeric rhizomes. However, the sun-dried turmeric rhizomes lost its product value because of poor quality end product (dark yellowish brown color). This could be due to longer exposure of the product in sun causes change in the volatiles and color in turn degrades the market value and fetches lower price to the farmer. And also decreased drying rate, prolonged drying time, non-uniformity, and lesser energy consumption are the other factors that degrades further the quality of the product. Hence, a drying technology should be identified to overcome the problems faced by the farmers and also to dry the bulk capacities of the turmeric rhizomes at low cost. Rotary dryers are capable of

“…The cost of the unit was estimated based on the materials used including turmeric rhizomes, dry biomass for fuel, and the cost involved in the fabrication of the rotary dryer. The calculation was done with standard procedure given by Perazzini, Perazzini, Freire, Freire, and Freire (2021) and Kudra (2015).…”

“…MC reduction can be done by using a drying system where the heat source used can be either stand-alone or by utilizing heat from the waste of industrial activity. The most common dryer types are rotary dryers [22][23][24][25], flash dryers [26], fluidized-bed dryers [26][27][28][29], and belt dryers [30,20]. Lee [13] in his experiment utilizing an electrical air heater found out that for reducing the MC of woodchip from 40 % to 10 % MC needed 23.0 min.…”

This paper is to study the drying method to reduce the moisture content (MC) of the woodchip. The methods used are to utilize the heat from solar and waste heat from the Biomass Power Plant (BioPP). By using a 250 °C heat waste from the BioPP, and stirring on the woodchip inside the drying equipment, the results obtained to reduce the MC from more than 40 % to MC around 20 % will take 2 h and 4 h faster than that which was not done on woodchips. Reducing MC from 40 % to 20 % will save 25.44 % on the woodchip consumption for combustion in the boiler of the BioPP. An analysis related to MC, CV, and woodchip consumption in generating electricity is also carried out. When MC is 26.70 %, the CV is 13.5 GJ T-1, and the woodchip consumption becomes 4.62 T h-1 and 1.31 T MWh-1, the energy produced is 764.7 kWh T-1. When the MC is higher, 47.68 %, causing the CV to become 9.8 GJ T-1, it is found that the consumption of the woodchips becomes 6.41 T h-1 and 1.81 T MWh-1, the energy produced is 551.3 kWh T-1.
