| Yhteenveto: | The processes of manufacturing and assembling a solar box-type oven with the base element
of a disused refrigerator for food baking are presented. The main feature of this oven was its
ability to bake various foods simultaneously, in addition to its low cost, as it can be
manufactured from recyclable elements. An energy balance of the proposed solar oven was
presented, determining its thermal loss and yield. The proposed solar oven was tested to
produce the baking of various types of food. The solar oven proved to be feasible to produce
the five-bolus bake, with a load of 3.62 kilos, in only 70 minutes, presenting superiority over
the conventional gas-fired oven, with a capacity of only two baking cakes, in about 50
minutes. The efficiency of the furnace under good solarimetric conditions, between 10:00 am
and 4:00 p.m., was 66.5%, competitive with other solar furnaces already studied in the
LMHES and presented by the solar literature for food cooking, between 40 - 70 %. The
economic feasibility of the studied solar furnace was also approached aiming at verifying the
possibility of use in poor communities, being able to become a source of generation income
and employment, as well as diffusing and massifying the use of solar energy for the roasting
of food, minimizing the serious ecological problems generated by the use of firewood as a
source of energy for cooking. |
