In-bin drying provides an alternative to traditional drying in terms of achieving good grain quality and saving fossil fuel. Some mathematical models were developed which could be used to simulate the in-bin drying process. To test the models’ ability for application, a partial differential equation model (PDE model) and a logarithmic model (Log model) were applied to simulate the heat and mass...

drying of green peas in a fluidized bed dryer (fbd) with inert particle, heated by combined sources of hot air and infrared (ir) radiation, has been experimentally and theoretically studied. for this purpose, an experimental set up was constructed. this setup was composed of a cylindrical bed dryer containing some inert particles which are fluidized by hot air. some infrared lamps were also pla...

Water-based pressure sensitive adhesives are typically latex suspensions and are often coated onto silicone-coated paper prior to being contacted with the face stock. It is necessary to control drying conditions to achieve low residual moisture in the PSA without formation of defects, and mathematical models can be effective tools to determine appropriate drying conditions. We will present two ...

Benefits in using model based predictive control during drying and lyophilisation. 3rd European Drying Conference joint conference of the European Federation of Chemical Engineering (EFCE) Drying Working Party, Association Française de Séchage dans l’Industrie et l’Agriculture (AFSIA), May 2009, Lyon, France. 23 (1), pp.100-101, Cahier de l’AFSIA. ...

An evacuated tube solar collector drier is designed and developed to study analytically and experimentally drying kinetics of Thompson seedless grapes in Pune, India. Drying experiments are carried out in the month of April- June for continuous three years from 2013-2015. During the experimentation, temperatures of hot and cold air at various places, ambient relative humidity and humidity varia...

During drying, stresses and deformations develop in a wood board due to shrinkage fi elds which result from moisture content and temperature fi eld variations. In spite of numerous works done in wood drying modelling in the last decades, wood drying optimisation based on modelling and simulation remains far from initial expectations. Two main reasons can explain this assessment: the huge variab...

"Observer based model predictive control of the water Based painting drying using a humidity profile soft sensor and a temperature measurement", This paper deals with the model predictive control of an infrared drying process of a water based epoxy-amine painting. During the drying cycle, the control problem is to optimize the use of the process under constraints. This approach is based on a no...

Certain deep indentations observed in dry coatings are referred to as "craters". They are believed to arise from gradients in the coating surface tension. A mathematical model of surface-tension-gradient-driven flow, using the lubrication approximation for thin layers, is developed to study the formation of craters. The paint is modeled as consisting of an evaporating "solvent" part and a nonvo...

Superheated steam drying technique has been known for a long time, but its application to food drying has received little attention. In this work, superheated steam was applied to dry fresh parsley (Petroselinum Cripsum). A mathematical model to simulate this drying process was developed by using mass and energy conservation equations for solid and steam phases. The resulting partial differenti...

A model for the simulation of timber drying in a batch kiln has been used for the investigation of a set of different questions related to this drying process. The model is global in the sense that it takes into account that the drying air local climate changes as it passes through the kiln load. In Scandinavian, practice kiln stacks are normally built from boards of random lengths so that ever...
