The study of this experiment is the drying curve based on the moisture content of the banana within the time taken. Theoretically the dryer occurs in this experiment by the supply of heat into the banana samples and use the air velocity in order passed over a heated element that act as mass transfer to evaporate the moisture contain in banana

The rotary dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material by bringing it in direct contact with a heated gas.The dryer is made up of large rotating cylinder which slopes slightly so that the discharged end is lower than the material feed end in order to convey the material under gravity.Material to be dried enters the dryer and as the dryer rotates,the …

computer simulation of a rotary dryer. part ii: heat and

Abstract. A computer model of a single-pass, rotary-drum dryer with or without a centerfill flighting section, describes the drying behavior of wood particles within the drum. This part of a two-part study examines heat and mass transfer, which are shown to be partly dependent on the pattern of particle flow and on retention time

using a tray dryer to investigate convective and

The rate of this process depends on the difference in vapor concentration between the interface and the bulk of the gas stream. The empirical proportionality constant here is the convective mass transfer coefficient. Although the coefficients can be estimated, they are unique to the solid being dried and the geometry of the tray dryer

[pdf] dynamic simulation of an industrial rotary dryer

Engineering Solid transport phenomena drastically affect rotary drying process. A change in any solid movement variable such as particle hold up or input flow rate results in a significant variation of heat and mass transfer rates. Therefore, in this research dynamic study of these phenomena was conducted both experimentally and theoretically
