Preferably, the heating device 22 is an electric heating wire.

In an embodiment, a temperature sensor 25 and a humidity sensor 26 are disposed inside the housing 21, and the temperature sensor 25, the humidity sensor 26 and the heating device 22 are respectively connected to the controller 38. Design like this, temperature sensor and humidity transducer implement and transmit the humiture information in the clamshell to the controller in, the controller operates according to the logic that has set up in advance, calculate when the temperature reaches how much can reduce the humidity of the material after smashing to predetermineeing the interval in, then increase heating device's power, reach the calculated value until the temperature, and, the controller can also control the functioning speed of conveyer belt, prolong the dry time of material in the conveyer belt, make its humidity reach the requirement.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
