Different drying methods viz., Sun drying, shade drying and tray drying (temperature 45, 55 and 65 0C) were used for dehydration of curry (Murraya koenigii) leaves for optimal retention of color and its constituents. It was observed that the time required for tray drying was less (27%), when compared to sun and shade drying. Tray dried (550C) curry leaves had maintained nutritional constituents...

The fluidized bed drying principles for drying of tea in Bangladesh is thoroughly studied. The experiments were conducted to determine the drying curve, drying time, drying constant and dynamic equilibrium moisture contents of tea at the Bangladesh Tea Research Institute. Drying of tea in a fluidized bed dryer (Kilburn Vibro Fluid Bed Dryer) takes only 20 min for drying from an initial moisture...

[1] This study uses a cloud-resolving model under the weak temperature gradient (WTG) approximation to explore the response of deep convection to imposed drying. The drying, intended to mimic horizontal advection of dry air, is imposed as a linear relaxation of the humidity field toward zero within a specified layer. Radiative cooling and sea surface temperature are held constant and there is n...

The dehydration tests were conducted at three drying methods to evaluate the drying curves and the energy uptake. Apple (Malus domestica L.) cubes were dried under different processing conditions applying freeze drying (FD), freeze drying assisted by hot air and freeze drying assisted by infrared radiation. Control samples were produced using regular freeze drying without the pre-drying. Hot ai...

This paper examines the influence of imposed drying, intended to represent horizontal advection of dry air, on parameterized deep convection interacting with large-scale dynamics in a single-column model framework. Two single-column models, one based on the NASA Goddard Earth Observing System general circulation model version 5 (GEOS5) and the other developed by Bony and Emanuel, are run in wea...

black tea sample was dried by a vibro-fluidized bed dryer to find its aerodynamic behavior and thermal performance during drying. the drying experiments were conducted at three different inlet air temperatures of 100, 115 and 130°c and fluidization condition at five vibration intensity levels of 0 (no vibration), 0.063, 0.189, 0.395 and 1.184. the results showed that bed channeling and defluidi...

The intermittent drying characteristics of an Iranian popular paddy rice variety were experimentally investigated to determine the drying kinetics and obtain the effective moisture diffusivity. A lab-scale fluidized bed dryer was designed and constructed to enable obtaining the required results while controlling critical drying parameters. The effects of drying temperature and tempering per...

a thin layer solar drying method was compared with a traditional method (sun drying) of paddy drying, with their effects on quality characteristics of two varieties of iranian rice (kamphiroozi and sazandegi) studied. solar drying process was conducted in a passive, mixed mode type solar dryer at about 50ºc for 90 minutes. in sun drying method this process took 8-10 hours at a mean temperature ...
