Abstract

In order to reduce the required manpower and biosecurity control risk for waterfowl breeding eggs, this study developed waterfowl automatic eggs cooling incubator which using the concept of pre-heating and pre-wetting type front control thermal system and add the automatic watering eggs cooling system, trolley egg rack, pneumatic eggs overturning system and monitoring system. The front control thermal system preheats and pre-wet the air to the required environment for hatching and import into incubator for the hatching test. The test results show that the hatching environment uniformity of automatic eggs cooling incubator developed by this study is better than the traditional incubator’s environment. The monitoring system can stable control the variation for three hatching parameters of temperature, humidity and carbon dioxide concentration. Besides the combination of automatic watering eggs cooling system for hatching process can significantly reduce the required manpower for watering eggs cooling and biosecurity control risk, the average hatching ratio is 82.06% that can satisfy the requirement of general professional goose breeding eggs incubator. The test using computational fluid dynamics simulation software (CFD) to simulate the variable turbulent wind speed. On the premise of using temperature as the respondence to conduct the optimization design of response surface methodology. The results shows that the incubator temperature standard deviation decreased from 0.26°C to 0.14°C when three turbulent wind speed changed from 4.25 m/s, 3.50 m/s and 4.63 m/s to 2 .00m/s, 5 .00m/s and 3.81 m/s. There is a further increase for the uniformity of the temperature field.
