る。In the figure, food waste 1 put into a food waste hopper 2 is cut into small pieces by a cutting machine 3 installed inside the hopper 2. The cut garbage 4 is fed into the evaporator/concentrator 5 while still having a high moisture content of about 90%, where the separation between evaporation of moisture and concentration of solids is carried out. Evaporation is performed by recovering waste heat, which will be described later, so thermal energy from outside the system is not required.

で冷却する為のエアフィンである。The evaporated steam passes through a mist separator 6, is superheated by a connected superheater 7, and then is introduced into a heating chamber 8. Heating chamber 8
The thermal energy of the outlet exhaust gas serves as a driving source for the superheater 7. The steam 9 whose heat has been recovered by the superheater 7 further recovers its thermal energy as energy for evaporating the volatile matter in the waste liquid. A heat pipe 10 recovers the thermal energy of the steam 9 into another fluid 11 as a heat transfer medium, and transfers heat as steam 12. In order to use this heat to evaporate volatile matter in the waste liquid, it is necessary to create a temperature difference that will serve as a driving source.
For this purpose, a heat pump 13 is installed. As a result, 120 to 1
Steam 15 can be produced which condenses at 40°C. The heated liquid 16 is circulated through the heat pipe 10. Therefore, the heat of the steam 9 is used as the heat of evaporation of the waste liquid, and is discharged as fresh water 17. 18 is an air fin for cooling at room temperature.
