Egg containers are egg transporters provide agriculturist to use, but egg transporters does not provide egg containers cleaning services. In order to ensure the use of egg containers health and safety, and improve the traditional human washing and sterilization. Establish a complete washing and sterilizing system for egg containers is extremely important. We divide speed of conveyer, placed way of egg containers, and the messy degree of egg containers to twelve statuses in experimental procedure and paint simulation experimentation under fixed liquid flow, spray angle of nozzle pipeline. Analysis and comparison for each of the different statuses do get the best cleaning mode and do sampling detection before and after washing egg containers. We use analysis software (Fluent) to simulate the fan speed when the wind blows through the mouth of its distribution after air-dried. Sampling detection indicates under the slow motion the number of colonies effectively reducing after washing(E. coli 93.6% and total plate count 65.7%). Consistent operating procedures also enhance the cleaning rate (42%).We can replace traditional wash from human labor by using automatic washing and sterilizing system for egg containers and increase the cleaning rate effectively. Simulation indicates that wind velocity is insufficient, we can take more powerful centrifugal fan to enhance the effect of air-dried.
