The hopper then flips back onto the lift rails under its own weight and slides down the lift rails back into the freezer.
On the other hand, the medical waste collected by the collecting and transporting unit 104 is loaded into a temporary storage after weighing. The medical waste is waste with direct or indirect infectivity, toxicity and other harmfulness generated by medical institutions in medical treatment, prevention, health care and other related activities, and specifically includes infectious, pathological, traumatic, medicinal and chemical waste, which may contain a large amount of pathogenic microorganisms and harmful chemical substances, so the collection and transportation unit 104 or the temporary storage can include a sterilizing device to perform high-temperature steam treatment on the medical waste.
The second conveying unit 105 is used for conveying the medical waste into the pyrolysis incineration unit 106 so as to be pyrolyzed and incinerated in cooperation with the animal carcasses. In one embodiment, the second conveying unit 105 comprises a chain plate machine. However, it is understood that the second conveyor unit 105 may also comprise any other suitable conveyor device, for example, the second conveyor unit 105 may be of the same or similar construction as the first conveyor unit 103.
