[0002] The pure product of mancozeb is white powder, and the industrial product is off-white or light yellow powder with a rotten egg smell. It is difficult to dissolve in water and insoluble in most organic solvents, but soluble in pyridine. It is unstable to light, heat and moisture, and is easy to decompose into carbon disulfide. It is easy to decompose and release carbon disulfide when it encounters alkaline substances or substances such as copper and mercury, which reduces its efficiency. It has low volatility and is easy to agglomerate when it is affected by moisture during storage. Therefore, in the prior art, before using mancozeb, the agglomerated mancozeb needs to be dried before use; currently, the drying of mancozeb is usually carried out by vacuum drying in a double-cone vacuum dryer.

[0028] Furthermore, a solenoid valve 10 is provided on the surface of the connecting pipe 9 .

[0029] Furthermore, heating plates 11 are provided at the bottom of both sides of the device body 1 .

[0030] Working principle: When in use, pour the agglomerated mancozeb from the feed port, and then start the first crushing motor 3 and the second crushing motor 4 through the controller arranged on the front of the device body 1, wherein the first crushing motor 3 and the second crushing motor 4 have different rotation directions. After the first crushing motor 3 and the second crushing motor 4 are started, the rotating shaft 12 will rotate, and the rotation of the rotating shaft will rotate the two crushing rollers 13, and the rotation directions of the crushing rollers 13 are opposite, so that the agglomerated mancozeb can be crushed.

[0031] It should be noted that after the first pulverizing motor 3 and the second pulverizing motor 4 are started, the heating plate 11 is immediately turned on by the controller to preheat the bottom portion of the filter plate 14 .

[0032] After the mancozeb is crushed to a suitable size, it will flow out of the filter plate 14 and then enter the bottom part of the heating plate 11. At this time, the temperature of the bottom part of the filter plate 14 has reached a suitable temperature by preheating, thereby drying the mancozeb.

The connecting pipe 9 transports the mancozeb inside the device body 1 to the inside of the screw conveyor housing 5, and then the screw conveying motor 6 is turned on by the controller. After the screw conveying motor 6 is turned on, the conveying shaft 17 will rotate. The rotation of the conveying shaft 17 will rotate the spiral blade 18, thereby transporting the mancozeb to the discharge port 7. By setting the conveyor, the dried powder can be prevented from clogging the discharge port 7.

[0035] It should be noted that, during the drying process, the staff turns on the rotary motor 8 through the controller, and the rotation of the rotary motor 8 will rotate the stirring shaft 15, and the rotation of the stirring shaft 15 will rotate the stirring blade 16, thereby stirring the mancozeb, so that the surface of the mancozeb can be dried, thereby improving the drying efficiency.
