The invention discloses an isolated type continuous tunnel vacuum furnace. The isolated type continuous tunnel vacuum furnace comprises a plurality of tunnel cavities, vacuum valves, a material carrying vehicle and normal-pressure valve plate doors. The plurality of tunnel cavities are linearly connected side by side. The vacuum valves are arranged between the adjacent tunnel cavities. The material carrying vehicle is slidably connected in the tunnel cavities. The two ends of the tunnel cavities are provided with the normal-pressure valve plate doors. Each normal-pressure valve plate door comprises a valve frame, an air cylinder, an air cylinder supporting plate and a normal-pressure plate valve, wherein the air cylinder is vertically connected and fixed to the top of the valve frame; an output shaft of the air cylinder is connected with the air cylinder supporting plate; the air cylinder supporting plate is connected with the normal-pressure plate valve. Each tunnel cavity comprises acavity body, a servo motor, an air cylinder, a cooling mechanism, a shifting tooth mechanism and a heating movable contact mechanism. The isolated type continuous tunnel vacuum furnace provided by the invention can guarantee high consistence of the drying quality of dried objects, and is smooth and compact in drying process, stable in performance. Equipment is automatic and integral. Manpower andmaterial resources are saved. The isolated type continuous tunnel vacuum furnace is high in drying quality and efficiency.
