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 …

Natural diamonds form deep underground, about 177 to 241 km below the surface. Pressures at this depth can reach nearly 50,000 atm. (One atmosphere, or “atm,” is similar to the air pressure at sea-level). Temperatures will vary from 900º to 1,300º C. These intense conditions compress carbon into its most compact type, making diamonds in …

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 …

Poultry litter is a nuisance, particularly once you don’t treat it well and leave it wet on a pile in or outside your poultry house. It releases high levels of ammonia inflicting poor environmental conditions for the birds and the employees inside the house as well as for the neighbors. Additionally, ammonia is seen as …

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 …
