方法を提供甘んとするものである。In this invention, animal waste is rapidly freeze-dried in vacuum to a moisture content of approximately 6%, and then oil is removed using normal hexane, thereby avoiding thermal denaturation of proteins and rancidity of oil. The present invention aims to provide a method for processing animal waste that can be dehydrated and deoiled and turned into feed and fertilizer containing high quality protein.

質のものとなる。Feathers, skins, and other animal excreta are used, and these wastes are shredded and vacuum-freeze-dried to a moisture content of around 6%, and made into powder, which is then treated with normal hexane. Boiling is also used to remove the oil contained in powdered waste that has been dehydrated by spraying or boiling, and the processed waste that has been dehydrated and oiled in this way is highly valuable as feed and fertilizer.

を行うもの１ある。Here, the vacuum rapid freeze-drying treatment method refers to a treatment method in which animal waste is rapidly frozen and vacuum-dried in the frozen state, and has the feature of improving water return properties.
The equipment consists of an airtight vacuum chamber, a heating machine, a refrigerator, its evaporator, water condenser, and four vacuum pumps, and the waste is first rapidly frozen. Then, the waste is vacuum-dried using a freezing process, and dehydration is carried out while preventing the water on the surface of the waste from freezing in a vacuum state.

がある。According to the present invention, the temperature used for dehydration processing or the drying process is 11J1! Since dehydration is performed by evaporating moisture by heating, it is performed by vacuum freeze-drying, which prevents denaturation of proteins due to heat, compared to dehydration using oil and oil temperature. Because it does not use oil, it is not affected by the acidity of the oil, and furthermore, because there is no oil extraction process after using the oil, there is no generation of frictional heat that conventionally occurs when pressing and removing oil with an expeller. Heat denaturation of proteins can be prevented, and the oil content in waste after dehydration can be easily removed with normal hexane, making it easy to produce high-quality feed and fertilizer from animal waste. be.
