This research aims to develop the design of vertical bed dryer which could dry corn kernel. The characteristics has been investigated. consists three chambers each in order facilitate inlet hot air stream, kernel chamber, and outlet wet air. Each chamber was separated by perforated plate steel. Air flew a blower heated 2 x 350 heaters. parameter was: (a) drying temperature, varied 50-60 oC, (b)...

An aerodynamic calibration device called ICARE is briefly described. ICARE is currently being used at the Nuclear Research Center of Saclay in France for the certification of instruments employed in measurement of artificial radioactive particulate airborne contamination. ICARE is essentially a blower. Aerosols calibrated in size and labelled with 137Cs or 239Pu are injected in the mainstream o...

The following is a review of some of the work that we have done since 2007 regarding the importance of molds in the phenomenon of sick building syndrome (SBS). In these studies we first examined mold contamination in air handling units (AHU). Our results showed that Cladosporium sp. were commonly recovered in AHU as growth sites and free spores. They were found mainly on the blower wheel fan bl...

Having builtin compression process, monotooth rotary compressor can reach larger discharge pressure with higher efficiency and lower discharge temperature when compared with Roots blower. So it is a good alternative for Roots blower used in various fields. In order to put this kind of compressor into market as soon as possible, theoretical and experimental study of the monotooth rotary compress...
