Brief Introduction:

Sludge Rotary Harrow Rolling Triple Level Mutli-loop Drum Dryer

Food waste contains high water an and organic matters. In addition, it contains a variety of unsaturated fatty acid. The matters are easy to decompose. It is easy to grow bacteria. But after drying, food waste will be good organic fertilizer. It can not only reduce health problems and reduce pollution, but also bring economic benefits.

General mathod to make food Waste to organic fertilizer: Separation and Dehydration, crushing, drying, pelleting, cooling and package. Food waste water content is more than 80%. After separation and dehydration, the moisture will be less than 60%. It needs to be dried to be organic fertilizer. For drying it more evenly, we will crush it and with air delivery system , it will be delivered to the belt conveyor and sent to drying unit. After material going into the cylinder: Firstly, the wet material will be scattered into small pieces by rotary harrow in the process of falling, and then, it is repeatedly grabbed, lift, fallen and beaten throughly. The surface area of the shattered materials increased rapidly, and contact with hot air sufficiently to transfer heat and mass. In the last cylinder of organic fertilizer drying, the temperature is cooler than the first and second cylinders, food waste organic fertilizer cools down, which reduces water content further. There are also soecial lifting and guiding boards on the cylinders which leads material going in multiple loops and dry over 6 times than normal three-pass dryer. After multiple level drying within three cylincer drum, the water content in food waste organic fertilizer can reduce to 13% and realizes deodorization function. Then through pelleting, cooling and package, the food waste will become good organic fertilizer.
