In the present work, an indirect solar cooking proposal is
shown. The proposal combines three technologies: evacuated
tubes, selective absorber, and compound parabolic concentrator
(CPC). The absorber used is an evacuated glass tube, with a
highly selectivity inner surface. The temperature reached by the
solar cooker is approximately 160°C, enough to cover the
cooking needs of all types of food; Irradiance, wind speed,
ambient temperature was measured, food cooking tests were
carried out, using an evacuated tube and a parabolic solar
concentrator; as well as evacuated tube without parabolic solar
concentrator. A compound parabolic concentrator was designed
with an acceptance angle of 15 degrees, the base of the solar
cooker was made with acrylic, the concentrator was made with
simple reflection mirrors, the clips were printed on a 3D printer,
the trays were made with food grade stainless steel, food
cooking tests were carried out, recording the weather variables
every 15 minutes. The development of this evacuated tube
duplex solar cooker project is not only important because it
involves the achievement of an academic purpose, but also
involves a social purpose. It is intended to provide an efficient
and economical solution that is attractive to multilateral
organizations capable of supporting its manufacture,
industrialization and distribution to achieve the massification of
the product with a real and lasting impact
