After dehydration by the pressure dehydration device, it enters the conveying machine and enters the drying process; the inorganic matter pool enters the drying process with the same scheme, and performs a second rolling separation and refinement process, and the organic matter can enter and be bagged to form the product organic fertilizer.

In the first process flow, the domestic garbage enters the flattening and dispersing machine a of the garbage sorting and separating machine vertically through the feed port, as shown in Figures 1 and 2. The general diagram of the garbage sorting and separating machine is shown in the accompanying drawing 1, which consists of a flattening and dispersing machine a, a rolling and separating machine b, a cutting and dispersing machine c, a barbed tooth dispersing machine d, and a wire rope separating machine e with a total of five layers of mechanical screens . The function of pushing and dispersing machine a is to push the garbage flat, break the bags and disperse evenly. The rubbish that is flattened and scattered and piled up falls into the second layer of rolling and separating machinery b. The rolling and separating machinery is composed of multiple sets of double-roller extrusion rolls 2 and roller vertical knives 1, see Figure 3. The rolling and separating machine has an extrusion force between 1 ton and 2 tons. The roller vertical knife 1 is composed of special-shaped convex and concave gears.

Scattered and littered garbage will be transformed into regular flat shape and reduced volume. Make the softer wastes reach a certain hardness after strong extrusion, which is favorable for decomposition. The strong extrusion effect enables effective dehydration of the water in the original water-containing garbage. In the process of extrusion and rolling, different special-shaped rollers can be added according to the characteristics of the actual waste to be processed, and irregular shapes can be cut into regular shapes. The crushed and separated rubbish falls into the third layer of cutting and dispersing machinery c.

Special equipment can make large hard objects into small pieces and powder state. Scattered and littered garbage will be transformed into regular flat shape and reduced volume. It can make softer wastes reach a certain hardness after strong extrusion, which is beneficial for decomposition. The strong extrusion effect enables effective dehydration of the water in the original water-containing garbage. Squeeze and roll the different shaped objects and add rollers according to the actual needs of processing waste. The rolling knives and vertical knives are installed on the extrusion machine, which can cut irregular shapes into regular shapes.

Accompanying drawing 9 is rolling flat drying device, and its function is rubbish flattening, rolling, drying.
