PEAR DRYING: PERSPECTIVES FOR CONVECTIVE DRYING AND NUTRITIONAL EVALUATION

Acta Horticulturae, 2008
The present study aimed the evaluation of the possibilities of introducing alterations in the method used traditionally to dry pears in Portugal, by direct open-air sun exposure, in order to modernize it, making it possible to be used in an industrial scale, being more profitable and allowing the obtaining of dried pears with a better quality.

Convection drying of porous material

Ceramics International, 1994
The kinetics of convection drying of flat tiles has been investigated experimentally in an industrial tunnel dryer. Applying the maximum allowed drying rate curve obtained for a flat tile in the first period of drying, a grapho-analytic model for the optimal management of the process has been developed.

Convective Drying of D Coal

Coke and Chemistry, 2018
The energy value of fossil fuels may be improved by changing their excess moisture content. In studying the development of heat and mass transfer in the heating of coal samples at a rate of 5°C/min in air, with the plotting of a complete differential scanning calorimetry (DSC) curve, it is found that initial heating of the coal sample is accompanied by

OSMO-CONVECTIVE DRYING OF GRAPES

Drying Technology, 1994
ABSTRACT In order to reduce browning of grapes during drying, a special drying method was developed and evaluated using a laboratory scale fluidized bed dryer. Fresh Thompson seedless grapes were initially dried by immersion in a fluidized bed of sugar. The mass ratio of grapes to sugar was 1:1.

Comparison of acoustic and convective drying

Journal of engineering physics, 1967
An investigation is carried out into the process of the drying of a ceramic disk involving the use of an acoustic field produced by a gasjet emitter fed by hot air (up to 140° 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.

Microwave and Convective Drying of Grapes

Transactions of the ASAE, 1993
Thompson seedless grapes were dried under forced convection and also combined convection and microwaves in a modified microwave (MW) oven. Effect of chemical pretreatment on drying rate was compared with fruits with no pretreatment. Different air temperatures and power levels were investigated. Dipping of fruits in hot alkaline solution of ethyl oleate

Convective Drying of Ginger Rhizomes

2018
This paper presents the results of convective drying of ginger rhizomes under blanched, unblanched, peeled and unpeeled conditions using the ars-0680 environmental chambers for the drying process and td1002a—linear heat conduction experimental equipment to measure the thermal conductivities of the ginger at six temperature levels ranging from 10 to 60 °

MODEL OF CONVECTIVE DRYING OF APPLES

Elektrotekhnologii i elektrooborudovanie v APK
The complexity of describing the drying of various materials requires experiments to determine the characteristics of the process in real time. Such studies are based on mathematical modeling using methods of identification and estimation of the proximity of the characteristics of the analytical model with the object under study, followed by correction.
