Abstract
The food waste pretreatment system is widely used in the EU and USA. Compared with food waste pretreatment system in China, systems in EU and UAS are relatively advanced and impeccable. Based on the characteristics of food wastes in China, in this thesis, some modifications of drum sieve – one important part of the whole system were done in order to improve the efficiency of separation meanwhile achieve the miniaturization of drum sieve.
The biggest difference between the traditional drum sieve and the new one designed in this thesis was that there were no any plates in the drum which made it possible to achieve the miniaturization of the drum sieve. And those plates in the drum were replaced by another machine – bag breaker. Besides the main tasks of this thesis was to design the parameters of each structural size of the drum sieve including the diameter of drum, the length of drum, the thickness of drum, the distribution and the size of the sieve holes on the surface of drum according to the required handling capacity and existing features of food wastes in China.
Apart from the structure designing, the selection of electromotor of drum sieve, proofread of shafts in the drum and in the bag breaker were also needed to be done. And the distance between the shafts and the bag breaking area were also calculated. After that, the manufacture and installation of drum sieve, some relevant inspections and maintains and some notices about daily operation were also told in this thesis
In last part, some introductions to the relevant existing food waste treating methods, the marketing analysis and potential perspective research of our new equipment were also presented.
To sum up, this new type of drum sieve designed in this thesis has the wide range of usage and potential marketing competence, that is to say, this type of drum sieve can be applied into personal business.
