Optimizing Plastic Performance Through Precise Heat Treatment

The heat treatment of plastics (known as annealing and Normalising) is important to make sure tight tolerances are maintained during precision machining, bonding and polishing and to avoid cracking and crazing. Heat treating also eliminates internal stresses and ensures higher mechanical and thermal properties. While not this essential heat treatment method, it’s virtually impossible to …

Fluid Bed Dryer Improves Granular Chemical Production

For a Manufacturer of proprietary granular chemical product, long production times and inconsistent drying times were the problems. A circular fluid-bed dryer/screener system from KERONE provided the solutions. With a circular fluid bed dryer/screener, converted material from storage containers is fed into the top inlet of the dryer by a bucket elevator. Within the fluid-bed …

Changes Chemical and Physical Properties During Microwave Drying of Rice

Conventional rice drying is performed using heated air that transfers energy to the surface of grain kernels by convection. The energy transfer within the kernel is done by conduction. Water is desorbed into the drying air from the kernel surface, and a moisture gradient is established within the kernel, with water molecules diffusion toward the …

Comparison of Conventional Heating and Drying Methods with Microwaves

The mechanism for drying with microwave energy is quite different from that of standard drying. In standard drying, heat is transferred to the surface of the material by conduction, convection or radiation, and into the interior of the material by thermal conduction. Moisture is initially flashed far from the surface, and therefore the remaining water …
