Drying Rates of Tablet Granulations I: Effect of Certain Granulating Adjuvants on Drying Rates

Journal of Pharmaceutical Sciences, 1975
The design and construction of a laboratory size dryer and other accessories suitable for investigating the drying rate kinetics of granules under controlled external conditions are described. Granulations of lactose and sulfathiazole, representing water-soluble and insoluble materials, were prepared using various commonly used binders, and their ...

Study on drying rate in contact drying with flexible screen

Journal of Forestry Research, 2000
The moisture contents (MC) of popular veneers were tested in Composition Board Laboratory of Northeast Forestry University by contact drying with flexible screen. The influence factors considered included temperature, initial moisture contents (IMC), and veneer thickness. Veneer-drying laws under different hot press conditions were analyzed.

On Prediction of the Drying Rate in Superheated Steam Drying Process

Drying Technology, 2011
The aim of the study was to determine how the drying rate in the falling drying rate period can be predicted in superheated steam drying. The study presents drying kinetics (determined experimentally) in the range of steam temperatures from 120°C to 200°C, with the superheated steam velocity from 0.18 to 0.40 m/s and under atmospheric pressure of a ...

Drying rate control in the middle stage of microwave drying

Journal of Food Engineering, 2011
Microwave drying of apples at constant temperatures follows typical drying curves. The middle stage of the drying process shows a faster drying rate and accelerated moisture evaporation. Meanwhile, more flavors are lost, surface color is degraded, and charring often occurs in this stage.

Enhancing Switchgrass Drying Rate

BioEnergy Research, 2017
Rapid drying to baling moisture reduces weather-related risks when harvesting perennial grasses to be used as biomass feedstocks. Drying switchgrass can be challenging due to large, dense swaths and unfavorable autumn drying conditions, so new methods to improve drying are needed.

DRYING RATE OF EAR CORN

Transactions of the ASAE, 2004
Thin-layer ear-corn drying tests were conducted at 35°C to 45°C and 5% to 35% relative humidity. The Page thin-layer drying rate model was parameterized for the product, with the drying rate constant as a function of initial moisture content and drying air temperature.

Freeze-Drying Mechanisms and Drying Rates Under Various Drying Conditions

1985
Freeze-drying rates of relatively homogeneous frozen materials and frozen particles in a shallow tray by radiative and conductive heating are studied both experimentally and theoretically. The drying mechanism of frozen materials of which initial ice content is less than 1.0 is quite different from the flat plane sublimation, which was found previously

Evaporation rates in spray drying

The Canadian Journal of Chemical Engineering, 1964
AbstractThe rate of evaporation of pure water droplets in a co‐current spray dryer was investigated. It was found that the relative motion between the droplet and the air stream is of significant importance in the determination of the rate of heat and mass transfer.

Evaporation rates in spray drying

The Canadian Journal of Chemical Engineering, 1960
AbstractHeat and mass transfer coefficients have been determined during the evaporation of water sprays produced by pneumatic atomizing nozzles in a vertical, cocurrent spray dryer, 8‐in. in diameter and 14 ft. high, under various operating conditions.

Effect of Drying Rate on Aerosol Particle Morphology

The Journal of Physical Chemistry Letters, 2017
The morphology of aerosol particles impacts their role in the climate system. In the submicron size regime, the morphology of particles that undergo liquid-liquid phase separation is dependent on their size, where for some systems small particles are homogeneous and large particles are phase-separated.
