Better understanding (and so better control) of the stickiness phenomenon of drying sludge is critical for proper operation of a variety of industrial dryers, as is the case for the combined centrifuge-dryer system used on the Monsanto Europe site in Antwerp, Belgium. In this paper a binary logistic regression analysis is performed on a 4-years data base, which resulted in an empirical model fo...

This community service aimed to educate the small and medium enterprises (SMEs) about management of production technologies in obtaining halal certification. The partners this program were UKM Meugah Pliek Wina Mandiri as pliek-u asam sunti processors Aceh Besar Regency. steps products that need technology are drying pressing process. had been conducted through survey, preparation, education. R...

In this study, four different apple varieties were dried in a solar tunnel dryer using methods. Apple slices immersed solution consisting of 0.5% ascorbic acid, sodium metabisulphite, and citric acid for 3 min. Constant measurements performed various parts the drying air temperature, irradiation, velocity, relative humidity during drying. The change mass apples was measured on daily basis. Furt...

Introduction The stability of the paper machine short circulation, forming and press section are tightly connected. A new online measurement, IQInsight, now provides true instantaneous MD and CD profiles from the press section. This unique measurement device provides new possibilities for stabilizing and optimizing paper machines. The accurate and continuous moisture profile just after the pres...

Spray dryers are widely used in the chemical, pharmaceutical and food industries to turn liquid products into free flowing powder. To increase the energy efficiency and improve the product quality, the dryer in question combines drying in four stages, instead of single stage drying. In this paper, we present our latest developments within advanced process control for the four-stage spray dryer....

Dryer system is a controlled plant which is normally used in chemical industry. The proper modeling of this system facilitates its maintenance and keeping. Normally this is not an easy task, unless having a complete model of the process, due to sudden and nonlinear events. In this paper the linear identification of dryer plant in Arak petroleum, is introduced according to the Autoregressive wit...

Drying kinetics of sour cheery is investigated in solar dryer with forced convection and under open Sun with natural convection. Drying data were fitted to different mathematical models, whose performance was investigated by comparing coefficient (R), reduced chi-square (Ç) and root mean square error (RMSE) between the observed and predicted moisture ratios. Among these models, drying model dev...

to increase agricultural crops’ quality and to minimize losses in the final product and used energy during the drying process, major drying system parameters should be continuously controlled. precise control of such parameters is attained by using automatic control systems. to optimize the overall dryer efficiency in a forced convective solar dryer, a controller was designed, constructed a...
