The invention discloses a quick
drying device for spraying. The quick
drying device comprises an elongated tunnel, a
heat exchanger, a blower and a heating device. A guide rail is fixed on the top wall of the tunnel, a product conveying frame capable of sliding along the guide rail is arranged on the guide rail, a plurality of hot air inlets are formed in the lower end of the side wall of the tunnel, a plurality of
cold air outlets are formed in the upper end of the side wall of the tunnel, a heating medium outlet of the heating device is connected with a heating inlet of the
heat exchanger through a pipeline, a heating outlet of the
heat exchanger is connected with a heating medium return port of the heating device through a pipeline, the blower is connected with an air inlet of the heat exchanger, a hot air outlet of the heat exchanger is respectively connected with the hot air inlets in the side wall of the tunnel through pipelines, and the
cold air outlets in the side wall of the tunnel are connected with an air inlet of the blower through a pipeline.
Drying temperature is uniform, products are not easily cracked, the tunnel is long and large in volume and contains more products, and the quick
drying device is low in cost, high in efficiency, low in
energy consumption and high in productivity.
