An analytical study describing the performance of a tunnel greenhouse drier is presented.Considering the greenhouse as a solar collector, a linear function between the incident solarradiation and the greenhouse output temperature is obtained. Using the drier characteristicfunction, the drier performance is evaluated as a function of the drying potentials. The resultsshow that an almost constant production is obtained each day. The generalized drying curveconcept is applied to the first tunnel cart, obtaining a result that is similar to the single chamberdrier case. The simulation tests with red sweet pepper show an improvement of 160% in theproduction, compared with the single chamber drier case, and an improvement around 40%,if the double chamber drier is considered.
