The present invention relates to a hot air convection belt-type drying system for use in drying coal or various agricultural products (such as peppers) and cigar leaves, et cetera. The present invention comprises: an insertion conveyer for aligning and inserting, on a drying conveyer, an object to be dried, the object being supplied by a supply conveyer; a drying housing comprising at least two drying chambers; a heat exchanger for supplying hot air to each of the drying chambers in the drying housing; a collection conveyer for removing dust which separates from the drying conveyer; a discharge conveyer for discharging dust and the object to be dried, which is supplied by the drying conveyer and the collection conveyer; cyclones which are connected to a final drying area and a discharge pipe in each of the drying chambers; a dust collection device, a gas collection device, and purifying devices which are sequentially installed on the discharge pipe that passes through the cyclones; and a boiler device for supplying hot water which is heated by the heat exchanger. The present invention can improve drying efficiency of the object to be dried by stacking the object to be dried so as to have a uniform thickness and passing same through a plurality of drying areas in which hot air is circulated, and can dry the object to be dried while preventing breakage or damage by minimizing external physical force that is applied to the object to be dried, thereby allowing the drying system to be utilized in a variety of fields.
