Abstract—This research work develops a forced internal convection dehydrator to improve the productivity regarding ginger dehydration in Pichanaqui and the objective is to design an internal forced convection dehydrator using a centrifugal fan to maximize the productivity and to improve the quality of the dried ginger. This research is based on the German design norm VDI 2221 which was adapted and complemented with the norm VDI 2225. Furthermore, it was added the state of the art and also 7 phases for the development of the objective. Those points were implemented in order to determine the list of requirements and desires, the abstraction process or black box, the sequence of operations, a solution analysis or white box, a morphology matrix, a technical economic analysis to finally obtain a preliminary project. The results of the mathematical modeling determined that for the feeding system there is a hopper and a worm screw that doses and transfers the fuel with a flow of 4.5 [kg/hour] to keep the heat generated inside the combustion system, which is made of 310 refractory stainless steel and vermiculite plate as thermal insulator, with internal tubes that function as filters and heat exchangers for the circulation system connected to a rectangular duct that joins both rooms circulating at 9. 012 kg/min of air forced by a fan of 4750 m3/h and with a dehydration temperature of 59.89°C, production capacity of 274.47kh/day, made of 304 stainless steel and glass wool insulation.
