Dehumidification device of package thermal-shrinking oven

A dehumidification device of a package thermal-shrinking oven, comprising:

• at least one thermal-shrinking oven body, which is combined with a packaging and conveying strip for conveying an object-to-be-packaged, two sides of a lower portion of the thermal-shrinking oven body being each provided with at least one connecting portion;
• at least one steam conduit, which is connected, at a lower end thereof, with at least one steam device, so that hot steam generated by the steam device is conducted into the steam conduit, two sides of an upper portion of the steam conduit being respectively connected to the connecting portions on the two sides of the lower portion of the thermal-shrinking oven body;
• at least one thermal isolation board, which is mounted to an upper portion of interior of the steam conduit and enclosing two sides of the packaging and conveying strip;
• at least one pair of first heaters, which are respectively mounted to exterior of two sides of the steam conduit to provide a first heating operation on the hot steam at two sides of the steam conduit to form moisture-removing dry hot gas for being subsequently guided along the two sides of the upper portion of the steam conduit through the connecting portions of the thermal-shrinking oven body into an interior of the thermal-shrinking oven body to implement a heat-shrinking packaging operation on the object-to-be-packaged located on the packaging and conveying strip;
• at least one second heater, which is mounted on a bottom of interior of the steam conduit to carry out the first heating operation, in synchronization with the first heaters on the hot steam at the bottom of interior of the steam conduit;
• and
• at least one pair of third heaters, which are respectively mounted to two sides of exterior of the thermal-shrinking oven body to carry out an enhanced moisture-removing effect in synchronization with the heat-shrinking packaging operation of the dry hot air in the interior of the thermal-shrinking oven body.
