Design of Heat Pump Drying Device for Livestock and Human Feces

The composition of livestock and human feces are relatively complex. In addition to being rich in organic matter, nitrogen, phosphorus, and potassium, there are also a large number of pathogenic bacteria, parasite eggs, antibiotics, and large doses of heavy metal additives. Livestock and human feces are good organic fertilizers, but if they are used without effective treatment, they will cause great damage to the environment. Because heat pumps have the advantages of low power consumption, environmental friendliness, easy automatic control, good quality of dried products, and saving drying time, heat pumps have been used to dry seafood, grains, and other materials. This paper set chicken manure as the research object, designed a set of heat pump drying devices to reduce and harmlessly treat the chicken manure, and used FLUENT software to simulate the drying oven, and drew the conclusion that the chicken manure can be dried evenly according to the set conditions in the drying oven.
