Green Drying: Continuous Dehumidified-Air Dryer

Simulation Model for Heat Pump-Assisted Dehumidified Air Drying for Some Herbs

A computer simulation model for the heat pump dehumidified air drying for garlic and white mulberry leaves was developed. The Modified Page model was found suitable in describing the drying curves. The computer simulation model was verified against heat pump dehumidified drying data of garlic and white mulberry leaves. The results revealed that drying air temperature and relative humidity influ...

Pulverizing Air Dryer

mathematical modeling of onion drying process using hot air dryer

the main purpose of present paper is the modeling of onion drying process and investigation of experimental data of onion drying obtained with using a hot air dryer. therefore some empirical and regression models have been considered to fit experimental data. the investigation of the experimental data shows the onion drying happens only in falling rate zone. the experimental data have been fitt...

mathematical modeling of green pepper drying in microwave-convective dryer

in this study, green pepper was dried by a laboratory scale microwave-convective dryer. the effects of microwave power on drying rate, effective moisture diffusivity, and energy consumption of green pepper were studied at four different microwave powers of 180, 360, 540, and 720w. the drying data were fitted to the four thin-layer drying models. the moisture reduction of the green pepper sample...

Drying of Municipal Sewage Sludge: from a Laboratory Scale Batch Indirect Dryer to the Paddle Dryer

Among available technologies, disk and paddle dryers are often encountered in France to process municipal sewage sludge but their thermal design is still a question of know how rather than scientific knowledge. From experiments performed on an industrial Naratherm paddle dryer and the literature, a simple model has been developed. The dryer is divided into two parts depending on the sludge cons...
