Tray dryer experiment sand

Tray dryer experiment sand

In this experiment, the tray dryer was used in order to remove water from the wet sand. The aim of this experiment is to generate two plots which are drying and drying rate for wet sand, and compare drying rate with data from psychometric chart and the data of weight loss. In this experiment, by plotting the drying curve, the moisture content and the weight loss were found to be decreasing as the time passes

    Jan 01, 2017 The tray dryer unit used in the experiment was first retrofitted with a PC, a data acquisition card and LabVIEW software. Then a 2 k full factorial design and analysis of variance (ANOVA) were used to analyze the operation of the retrofitted dryer by the variation of two parameters: air temperature and velocity. The interactive effects of these

    Repeat Step 6 with the wet sand. Next, make similar structures with dry soil and dry sand, for a total of four structures: one made from muddy soil, one dry soil, one wet sand, and one dry sand. Now that your creations exist, it's time to see which stand up to wind and water. Use your battery-operated fan to blow air on the four structures

    A typical batch tray dryer consists of an enclosed, insulated housing in which trays containing solids are placed on shelves. Direct heat transfer is achieved by circulating a large volume of hot gas between the trays. Indirect heat transfer requires the use of heated shelves. Tray dryers can be operated under vacuum with indirect heat transfer
