Technical Field
The utility model belongs to kitchen garbage handles the field, concretely relates to a processing apparatus for kitchen garbage.
Background
With the development of economy and the improvement of the living standard of people, the discharge amount of kitchen waste is increased day by day, a large amount of kitchen waste brings serious influence to the living environment and the health of people, the government of China pays high attention to the waste treatment problem, and the development of a kitchen waste treatment machine is imperative.
The existing kitchen garbage disposal machines are mainly divided into the following two types. The microbial decomposition type processor utilizes organic microbes to degrade organic matters in kitchen waste and convert residues into fertilizers, the processing mode better reflects the idea of waste utilization, but more problems exist in practical use, firstly, the salt content of compost is higher, which is not beneficial to the use of the fertilizers, secondly, due to the limitation of the process, the kitchen waste processing usually needs more than one day, which puts higher requirements on the deodorization and storage of the waste, the kitchen waste needs to be cleaned every day, and the indoor air environment is deteriorated due to frequent opening of the device.
Another type is a shredder type disposer, which is typically mounted under a sink and drives a cutter head by a small dc or ac motor. Utilize centrifugal force to smash the food waste of intracavity, then directly arrange the sewer into, this kind of processing apparatus is not suitable for popularizing by a wide margin at home, this is because the kitchen garbage after being smashed forms tiny particulate matter, and they deposit in the pipeline very easily, can increase the risk of pipe blockage. In addition, due to the catering habits of Chinese people, the oil content of the kitchen waste is high, and the oil is easy to adhere to the pipeline when meeting low temperature, so that the risk of blocking the pipeline is further increased. Meanwhile, when the crushing mechanism crushes food, a large amount of resistance is caused due to a large amount of water in the food waste, so that the crushing effect is poor.
