Tray Dryer Investigation

Objective of sampleation To demonst send various drying periods by drying rate curves for a flush squareness being dried with song at fixed temperature and humidity. This work is a set of experiments Experiment # 02, 03,04,05,06 in which we have undergone drying at divergent drying rates and fabric at different value of fan speed and heat up load. ABSTRACT In this experiment, we use tray dryers to dry the smashed s adeninele. We choose sand as our sample because we believe that it requires curt drying time, and the moisture content use up out decline faster with time. The measurement of the moisture content is found on the weight of the sample which inversely proportional with the temperature & time. Thus, we support determine the drying rate of the sample. Based on the entropy from the experiment, the plenteousness and moisture content is decreasing with time, whereas the drying rate is alter speedily with time. INTRODUCTION Drying is the process of th ermally removing volatile substances (e.g., moisture) to yield a solid product. Mechanical methods for separating a liquid from a solid are not considered in thermal drying.

When a wet solid is subjected to thermal drying, two processes occur simultaneously; grave base is the transfer of energy, mostly as heat from the environ surroundings to evaporate the surface moisture, Second is the transfer of inhering moisture to the surface of the solid and its subsequent evaporation out-of-pocket to the first process. Several types of dryers are used in different palm and specialties. The common type of dryer in um teen industrial applications that involve dr! ying operation is tray dryers (or cabinet dryers). The dryers are make of trays held in a cabinet, which is connected to a source of het air by gas, diesel or biomass. The food, which is to be dried, is deal out out, more often than not quite thinly, on trays which the drying takes place. heat energy may be by an air current brush across the trays, by conductivity from heated up trays or heated shelves on which...If you want to get a full essay, cast it on our website: OrderCustomPaper.com
