Beet residue is a by-product of sugar making, a good juicy feed for livestock, the main component is soluble nitrogen-free substances, but little protein and fat, very high calcium, less phosphorus, strong palatability, and more crude fiber. The water content is about 85%, so it cannot be stored for a long time, but can be stored after drying.

Sugar beet pulp dryer, which is also named impeller mixing rotary drum drier, rake roller dryer, rotary rake drum dryer, rotary paddle roller dryer. It is specifically designed according to the problems of the traditional rotary dryer which is not suitable for high-moisture materials that MC is higher than 50% and the viscosity is relatively low. Meanwhile, since the 'black hole' phenomenon occurring in the drum lowers the drying capacity and raises the energy consumption, the paddle rotary dryer sets high-speed spinning paddles, strengthening the crushing and separating function. The crushing effect enlarges the contact surface of particles, which largely increases the heat transfer rate and vaporization rate. According to the practical test, the unit vaporization capacity per hour of paddle rotary dryer is as much as 25-60kg /m2, which is 1-2 times of traditional rotary dryer. The output is raised by 50% and fuel consumption is reduced by 30%. At the same time, the footprint and drying efficiency is raised by 40%.
