The invention discloses a tunnel type dryer based on drying effect. The tunnel type dryer based on the drying effect comprises a support, wherein a conveying mechanism is arranged at the upper end of the support, a preheating device, a sterilizing device and a cooling device are sequentially arranged along the moving direction of the conveying mechanism on the support, the sterilizing device comprises a shell, the conveying mechanism is arranged below the interior of the shell, the heating device is arranged above an air inlet of the interior of the shell, an air gathering drum is arranged inside the shell, an air inlet vent matched with the heating device is formed in the side wall of the air gathering drum, and a heating laminar flow fan matched with the air gathering drum is arranged on the shell; a connecting plate is arranged at an air outlet end of the air gathering cover, a plurality of ventilation pipes are vertically arranged on the connecting plate, and ventilation holes are formed between adjacent ventilation pipes on the connecting plate; and multiple deflectors are arranged at one side, opposite to the air inlet vent, in the air gathering drum. The tunnel type dryer disclosed by the invention can be used for solving the problem that drying effect of an existing drying system and dispersion uniformity of drying hot air flow dispersion can not be balanced, and speed of introducing drying hot air flow can be effectively improved.
