Abstract

A method and a device for drying an explosive, wherein the explosive contains moisture and microwave radiation causes the explosive to expel the moisture contained in the explosive. Provided is a drying chamber having magnetrons that exert the required microwave radiation on the explosive to be dried and thereby heat the explosive. During heating, the moisture in the explosive is then expelled.

Claims (17)

1. A device for drying an explosive that contains moisture, the device comprising:

a drying chamber in which the explosive is dried;

a support device on which the explosive is stored;

at least one magnetron being associated with the drying chamber, via which the explosive is subjected to microwave radiation,

wherein the support device is a transportation belt, which has a transportation direction,

wherein a first chamber is provided and is positioned upstream of the drying chamber,

wherein the transportation belt extends through the first chamber and the drying chamber so that the transportation belt guides the explosive through the first chamber and then through the drying chamber,

wherein the first chamber includes further magnetrons so that a heating of the explosive in the first chamber is provided, and

wherein an adsorption device, that subjects the explosive to adsorption, is provided in the first chamber.

2. The device as claimed in claim 1 , wherein at least one sensor is associated with the drying chamber, which permits a moisture and/or temperature measurement.

3. The device as claimed in claim 1 , wherein a second chamber is downstream of the drying chamber, and wherein the transportation belt extends through the second chamber so that the transportation belt guides the explosive through the second chamber after the drying chamber.

4. The device as claimed in claim 3 , wherein cooling elements cool the explosive in the second chamber.

5. The device as claimed in claim 3 , wherein an additional adsorption device is provided in the second chamber to subject the explosive to adsorption.

6. The device as claimed in claim 1 , wherein a running speed of the transportation belt is variable.

7. The device as claimed in claim 1 , wherein the wavelength of the at least one magnetron is variable.

8. The device as claimed in claim 1 , wherein at least one fan is provided, which exhausts the air in the drying chamber to outside the drying chamber.

9. The device as claimed in claim 8 , wherein the fan has at least one moisture filter.
