1.In drying by normal drying machine, since the machine is still, hot wind penetration is insufficient, the material is will agglomerate easily and result in jams and blocks, so complete dry effect can not be reached. The design of this machine includes two stages of spiral rapid transports. The first stage is to move the raw material to the barrel. The second stage is to rapidly lift the material to the top of barrel and scatter it in shape of umbrella. Hot wind will blow upwards and penetrate the raw material,dynamic drying with complete heat exchange is conducted. 2.Since the raw material in the barrel is continuously rolling,hot wind is continuously blowing from the center, so mixing and drying is synchrionously conducted, so it saves time and power. If drying is not needed, dry switch can be turned off, then the machine has only function of mixing. This machine can also be used for mixing of granulate material and powder material. 3.The barrel body, spiral vanes, shaft, cylinder, support frame and the parts which touch the raw material are all made of stainless steel. 4.When the material need clearing, open the material clearing opening and let the spiral vanes rotate in counter direction.Material clearing can therefore be sinply operated.
