| সংক্ষিপ্ত: | The growing need for food is something that worries the world, which has a population that is
growing at a geometric progression while their resources grows at an arithmetic progression.
To alleviate this problem there are some proposals, including increased food production or
reduce waste thereof. Many studies have been conducted in the world in order to reduce food
waste that can reach 40% of production, depending on the region. For this purpose techniques
are used to retard degradation of foods, including drying. This paper presents a design of a
hybrid fruit dryer that uses solar energy and electric energy with automation of the process.
To accomplish drying tests were chosen Typical fruits with good acceptability as processed
fruits. During the experiments were measured temperature values at different points. Were
also measured humidity values, solar radiation and mass. A data acquisition system was built
using a Arduino for obtaining temperatures. The data were sent to a program named Secador
de Frutas, done in this work, to plot the same. The volume of the drying chamber was 423
liters and despite the unusual size test using mirrors to increase the incidence of direct
radiation, showed that the drier is competitive when compared with other solar dryers
produced in Hydraulic Machines and Solar Energy Laboratory (LMHES ) UFRN. The drier
has been built at a cost of 3 to 5 times smaller than industrial dryers that operate with the same
load of fruit. And the energy cost to produce dried fruits was more feasible compared with
such dryers that use LPG as an energy source. However, the drying time was longer. |
