Microwave drying kinetics of a clay-plate

Ceramics International, 1995
This study presents the development of an exponential model for the description of kinetics in the drying process of a porous material under the condition of dielectric heating. The model describes the changes in moisture content and in the rate of drying related to the duration of the process, as well as the moisture content in the material to be ...

Drying kinetics of polymer films

AIChE Journal, 1998
AbstractDrying kinetics of a polymer film cast from a polymer–soluent solution is studied. A modelization of the whole drying process is performed, including the difision of soluent through the varnish layer, the moving interface, and the coupled heat and mass transfer between the interface and the drying air.

Kinetics of safflower seed drying

Food processing industry, 2022
Сафлор является одним из древнейших масличных и красильных культур, чьи ценные пищевые, кормовые, технические, лечебные косметологические и диетические качества используются человечеством уже более 4000 лет. За последние три десятилетия в Казахстане сафлор используется и широко применяется в фармацевтической и пищевой, аграрной промышленности.

DRYING KINETICS

The three fundamental techniques for drying food include surface diffusion on pore surfaces, liquid or vapor diffusion resulting from changes in moisture content, and capillary action induced by surface forces in granular and porous food products. The thin-layer drying process of food products is significantly influenced by various variables, including

Dry grinding kinetics of colemanite

Powder Technology, 2007
Abstract The kinetics of batch dry grinding of colemanite from the feeds of sieve sizes − 2.360 + 1.700, − 1.700 + 1.180, − 1.180 + 0.850, − 0.850 + 0.600, − 0.600 + 0.425 and − 0.425 + 0.300 mm has been determined using a standard Bond mill. The specific rates of breakage ( S i ) and primary breakage distribution ( B i,j ) values, called ...

Kinetics of drying apple slices

Journal of the Science of Food and Agriculture, 1969
AbstractThe process of drying apple tissue under most conditions may be divided into two main periods viz primary and secondary falling‐rate periods. For most drying conditions the secondary falling‐rate period is longer and has the greater influence on the overall rate.

Phase Separation Kinetics During Drying

MRS Proceedings, 1996
AbstractKinetics of phase separation at air/polymer interface in a binary polymer mixture on evaporation of common solvent is studied. The lateral dimension of the highly anisotropie, pancake-like, minority phase increases with a growth exponent of 2/3 identical to ‘late-stage’ growth under (classical) thermal-quench at interface.

DRYING KINETICS OF SOME FRUITS

Drying Technology, 1997
ABSTRACT Drying kinetics of four Fruits (namely, apple, pear, kiwi and banana) were studied by introducing an one-parameter empirical mass transfer model, involving a characteristic parameter (drying constant), as a function of process variables. The model was tested with data produced in a laboratory dryer, using non-linear regression analysis.

Kinetics of coal drying‐decomposition

AIChE Journal, 1982
AbstractA series of seven coals of different ranks and from various locations were heated in an inert atmosphere under relatively mild conditions to measure the rates of gas evaporation. Samples crushed to various fractions in the particle size range −6+50 U.S. mesh were studied at temperatures in the range of 150 to 300°C.

Convective drying kinetics of raspberry

2023
The drying kinetics of raspberry in a laboratory dryer was studied. Fresh, untreated raspberries were dried at selected temperatures of 50 °C with a constant air velocity of 1.2 m/s. The drying rate curves showed that drying process took place only in the falling rate period.
