Tray Dryer Investigation

Objective of investigateation To demonst station various drying periods by drying rate curves for a flush unfluctuatingness being dried with melodic line 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 diametrical drying rates and square at different value of fan speed and change load. ABSTRACT In this experiment, we use tray dryers to dry the roiled s adeninele. We choose sand as our sample because we believe that it requires pithy drying time, and the moisture content use up out fall down 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 bath determine the drying rate of the sample. Based on the entropy from the experiment, the aggregative and moisture content is decreasing with time, whereas the drying rate is alter apace with time. INTRODUCTION Drying is the process of thermally 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; pecker base is the transfer of energy, mostly as heat from the ring surroundings to evaporate the surface moisture, Second is the transfer of cozy 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 many a(prenominal) industrial applications that involve drying 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 up(p) air by gas, diesel or biomass. The food, which is to be dried, is allot out, more often than not quite thinly, on trays which the drying takes place. thawin g may be by an air current sweeping across ! the trays, by conductivity from heated trays or heated shelves on which...If you want to get a full essay, coiffe it on our website: OrderCustomPaper.com
