In recent years, with the improvement of people's living standards, the production of kitchen waste has been increasing, and the treatment of kitchen waste has become a major challenge today. Based on the characteristics of kitchen waste, research on kitchen waste treatment technology and equipment has also received attention. At present, there are three main types of methods for treating kitchen waste:

① Crush the kitchen waste and directly discharge it into the sewer;

② Mainly based on reduction, also known as drying, using heating to evaporate water and reduce the volume and quality of garbage;

③ Mainly based on resource utilization, also known as biochemical formula, it uses bacteria to decompose organic matter and use the remaining residue as fertilizer.

　　The advantages of kitchen waste treatment equipment designed based on horizontal disc drying technology are that it does not have secondary pollution, occupies a small area, has low operating costs, and is easy to operate. It can be used in restaurants, unit restaurants, residential kitchens, and other departments where kitchen waste is generated in large quantities, such as garbage stations.

Drying process flow of kitchen waste

　　After pre-treatment, sorting, and crushing of kitchen waste, it is transported to a damp heat sterilization kettle for high-temperature cooking, which can achieve the killing of harmful microorganisms in kitchen waste; It can also change the water holding structure and effectively remove salt and oil from kitchen waste. The steamed material is divided into solid and liquid phases after solid-liquid separation: the solid phase enters the disc dryer and is dried at low temperature to form feed additives/fertilizer crude products. During the drying process, microbial agents are added to convert animal protein into mycelium protein and improve nutritional composition. The crude products can be processed through screening, packaging, and other post-processing processes to form final products; After the liquid phase is separated by oil and water, the generated crude oil can be processed into green energy - biodiesel. The high concentration organic wastewater generated in the process enters the water treatment system for treatment and is discharged up to standard.

Main characteristics of horizontal disc dryer for kitchen waste

① Completing the entire drying process in a closed environment is more suitable for odorous materials such as kitchen waste.

② This machine heats simultaneously through a jacket on the outer shell and internal stirring, resulting in a large heat transfer area and high thermal efficiency.

③ This machine is equipped with a stirring device to form a continuous circulation state of materials in the cylinder, further improving the uniformity of material heating and improving the heat and mass transfer effect.

④ The design is reasonable and advanced, easy to install and debug, and can adapt to various conditions for placement.

⑤ Can reduce labor intensity and improve work environment.

⑥ The main machine automatically feeds and feeds, with good effects in stir frying, cutting, mixing and crushing.
