The procedure is. Lead to half a kilogram of beef dried on the threshing,.Solar ovens and solar oven invented by the convex mirror attached to the steel structure below. The aluminum structure is the first glass plate on top of 45 degrees to the light.Place the oven rack in the middle of two sheets of stainless steel roller. Brick and iron sheet and spray the black at the end to absorb light and heat from the second heat added by lens 6.

How action is taken and a half kilos of dried beef going on kradong,Solar ovens, solar oven, convex lenses that are fabricated by applying glass fitted with steel structures below. Above is a structure of aluminium by using glass plates 1 installation above 45 degrees-to receive light. In the middle of the oven, place the sieve plates and 2 Hymenoptera reflecting steel sheets, steel and brick sprayed black paste here late to attract light and absorbs the heat from the heat energy added with 2 lenses embossed 6;

Is there a way to do this is to bring beef half-kilogram dried on a winnowing basket,the oven, oven, solar energy and Solar Energy lens convex the invention by the glass and steel structure attached to the bottom of the aluminum, using a clear glass plate 1 attached to the top angle 45 degrees to the lightin the oven, in the middle of the basket สะแต, stainless steel sheets 2 and remove the disc and brick Mon spray black place astonishment at the light and vacuum to suck the heat from the thermal energy 2. Add 6 convex lens.
