DIFFUSION COEFFICIENT FOR CORN DRYING

Transactions of the ASAE, 1990
ABSTRACT Recently, diffusion theory has been increasingly applied to describe the drying of agricultural grain. This requires a knowledge of the diffusion coefficient as a function of temperature and moisture content. Based on published data, a relationship was developed for the diffusion coefficient of com.

Drying Model and Moisture Diffusion Coefficient

Advanced Materials Research, 2012
Varied values of moisture diffusivity estimated using Crank’s equation with different initial moisture content, equilibrium moisture content and sample thickness are often reported. However, a theoretical explanation to this phenomenon is not available to date.

Diffusion coefficients for predicting rice drying behaviour

Journal of Agricultural Engineering Research, 1982
Abstract Recent efforts to characterize moisture diffusion in rice are summarized. New equations for temperature dependent liquid diffusion coefficients for rough and brown rice are presented. Result sindicate that the resistance to moisture movement is greater in rough rice than in brown rice.

Accurate measurement of dry friction coefficient using reciprocating tribometer

2018 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2018
A tribological test is adopted to estimate the kinetic friction coefficient of the material of interest according to the ASTM standard. Typically a number of replicate is necessary to take into account the observed casual variability of the measurand as well as a post-processing data treatment is recommended.

Mass Transfer Coefficients and Drying Rates in Through Air Drying: Part II

Drying Technology, 2009
In this study experimental results and analysis are given of convective heat and mass transfer in the drying of tissue and towel products (25 and 50 g/m2 basis weight) under commercially realistic conditions under through flow. Parameter effects on drying rate include process variables such as refining, shaping, commercial forming, initial moisture ...

Heat transfer coefficients for drying in pulsating flows

International Communications in Heat and Mass Transfer, 1998
Pulsating flows generated by a Rijke type combustor are studied for drying of grains and food particles. It is assumed that the velocity fluctuations are the main factor in the enhancement of the drying process. The heat transfer coefficients for drying in vibrating beds are utilized to estimate the heat transfer coefficients of fixed beds in pulsating

Comparison of vial heat transfer coefficients during the primary and secondary drying stages of freeze-drying

International Journal of Pharmaceutics, 2023
This study uses a heat flux sensor and temperature probes to directly measure vial heat transfer coefficients (Kv) during primary and secondary drying stages of lyophilization. It is observed that Kv is 40-80% smaller during secondary drying than primary drying, and this value exhibits a weaker dependence on chamber pressure than in primary drying ...
