Construction and Design
The Tray Dryer NutriForge - 04 is built around a rectangular duct forming a drying channel approximately 2000mm long, with internal dimensions of 350x350mm. An axial flow fan at the left end of the duct draws air into the space, rated at 33W power, a maximum output of 700m³/h, and a maximum speed of 950min⁻¹. A bank of electric heaters, rated 0 to 3500W with an adjustable temperature limiter, enhances the air's temperature after the fan. Four removable, corrosion resistant trays, each 300x300mm, hold the drying material inside the channel. A balance above the duct holds the rack of trays, with a measuring range of 0 to 10000g and a resolution of 0.1g. A combined temperature and humidity sensor measures conditions before and after the solid sample, while a separate sensor measures air velocity. A transparent door in the drying channel allows the drying process to be observed.
