Experimental dryer design for agricultural products

design principles of experimental fluidized bed dryer for some agricultural products

in order to study the fluidization behavior of grains, a laboratory fluidized bed dryer (fbd) was designed and developed. forward blade centrifugal fan with 1.5 kw electric motor, was selected to be used based on the highest pressure loss calculated at minimum fluidization condition and airflow rate at terminal velocity of the selected grains (paddy, soybean, millet and barley). the dryer was c...

Review on the Application of a Tray Dryer System for Agricultural Products

Application of tray dryer is widely used in agricultural drying because of its simple design and capability to dry products at high volume. However, the greatest drawback of the tray dryer is uneven drying because of poor airflow distribution in the drying chamber. Implementing the proper design of a tray dryer system may eliminate or reduce non-uniformity of drying and increases dryer efficien...

Biological Variance in Agricultural Products Experimental Examples

Based on the colour development of tomatoes (theoretical) and apples (measured) as an example the approach to biological variance from a new perspective is made more clear and more explicit. The origin of biological variance is traced back to the stage of maturity at the moment of harvest. By modelling the colour development of individual units in a batch in a generic fashion, and using this mo...

Image Analysis for Agricultural Products and Processes

Variability of weed infestation needs to be assessed for site-specific weed management. Since manual weed sampling is too time consuming for prctical applications, a system for automatic weed sampling was developed. The system uses bispectral images, which are processed to derive shape features of the plants. The shape features are used for the discrimination of weed and crop species by using a...
