Th e drying characteristics of “Granny Smith” apples were analysed using a tunnel drier at diff erent temperatures and diff erent pre-treatments. „Granny Smith“ apples were cut into rectangle-shaped samples 20x20x5 mm in size. Th e drying temperatures for non-treated samples varied from 50oC to 80oC at airfl ow velocity of 2.8 m s-1. Prior to drying at 60oC, the samples were pretreated either t...

the efficiency of oil extraction from oil seeds is affected by seed harvesting time, drying methods, seed storage conditions and finally the means of seed transportation to the factory. to determine the grain moisture content at harvest  and its effect on seed while on drying trails, (employing different canola dryers), a study was conducted in mazandaran province in 2009. a factorial complete ...

The effect of the initial moisture content (X(0)) of amaranth seeds on expansion volume after popping was examined in hot air and superheated steam (SHS), using a fluidized bed system (FBS). The moisturized seeds were prepared under various vapor pressures due to various saturated salt solutions. In hot air, the maximum expansion volume was shown by seeds having X(0) of 0.16 at 260 degrees C fo...

We commercialized Reactive Coke Agglomerate (RCA), a cement-bonded pellet to decrease the thermal reserve zone temperature for the reduction of the reducing agent rate of blast furnaces. To achieve a high productivity of supplying RCA to large blast furnaces, a rapid curing process of RCA using steam was investigated. We obtained rapid curing of RCA within 18 h by combining primary curing for 1...

The presented article describes two basic technological blocks of so called Flexible power unit which is located in the grounds of the Vı́tkovice company Ostrava in the Czech Republic. The experimental unit was established to research the use of potential energy in a mixture of dry air and superheated steam, which is called air/steam mixture. Creation of air/steam mixture is carried out by mixer...

Experimental results on industrial applications of the MUSMAR adaptive Predictive Controller are reported in this paper. They concern superheated steam temperature control in a thermoelectric power unit, oil temperature control in a distributed collector solar field, and trailing center line rate of cooling in a arc welding process. The processes considered are described, with an emphasis on th...
