Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

Examples

Referring to fig. 1 and 2, the sealed dryer adopting the lower blowing and return air circulating system in the present embodiment includes a dryer body 1, and a plurality of detachable side plates 2 are respectively and fixedly mounted on left and right sides of the dryer body 1. The top of the inner cavity of the machine body 1 is fixedly provided with a heating device 7, and the top of the machine body 1 is fixedly provided with a temperature controller 6 for controlling the heating time and temperature of the heating device 7. The heating device 7 is a steam heating device or an electric heating device.

And leather curtains 8 are respectively arranged at the inlet and the outlet of the two ends of the machine body 1. A supporting plate 3 made of stainless steel is fixed in the machine body 1 from an inlet to an outlet of the machine body 1, an air distribution plate 4 is arranged above the supporting plate 3, a plurality of ventilation holes 41 are uniformly distributed in the air distribution plate 4, and a conveying chain 5 for conveying tableware passes through the upper part of the air distribution plate 4.
