It consists of a high-speed rotary motor 72m, a frame 72f for supporting the high-speed rotary motor 72m, the outer preheating vessel 74 is formed in a cylindrical shape, for example, the bottom surface is convex upward. It was formed so that the water (22) dropped to the bottom flows to the corners and is configured to further increase the evaporation efficiency, the heater 76 is installed on the outer peripheral surface of the preheating vessel (74).

Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

1 to 5, food waste 20 is introduced into the hopper 30 while the passages leading to the hopper 30 and the crusher 40 are closed by the shutter 35a. When the shutter 35a is opened again, the food waste 20 in the hopper 30 flows down to the grinder 40.

In this case, when the food waste 20 includes metallic foreign matter, the alarm 120 is detected by the metal detector 100 attached to the outer surface of the hopper 30.

In this case, the operator stops the operation of the machine and then removes and removes metallic foreign substances (eg, cutlery, chopsticks, coins, etc.) from the food waste 20 put into the hopper 30, and restarts the machine. You can do it.

At this time, when the grinding device 40 is operated, the food waste 20 flowing down by the cutters 44 and 45 formed on the circumference of the rotating bodies 42 and 43 is pulverized finely and again the compression tube ( 54, and when the shutter 35a is closed again while a certain amount of food waste 20 flows into the compression tube 54, the food waste 20 is further moved to the compression tube 54. It won't flow.

That is, when the shutter 35a is not used, all of the food waste 20 in the hopper 30 overflows excessively into the compression tube 54, so that the inflow amount can be adjusted using the shutter 35a. will be.

When the stopper motor 82 constituting the variable stopper 80 is driven in the above state, the piston stopper 86 crosses the steam discharge pipe 57 by a linear transfer mechanism composed of a ball screw 84 and a nut. It is inserted into the compression tube 54 so that it stops at the compression position on the compression tube 54.

At this time, the hydraulic cylinder 53 advances to the place where the piston stopper 86 is interposed between the food waste 20 and compresses the food waste 20 therebetween.

In this process, the water 22 contained in the food waste 20 compressed between the piston stopper 86 and the piston 52 is squeezed out, and the upper portion is formed through the ejection hole 54a formed in the lower portion of the compression tube 54. It flows into the drip tray 55.

Then, when the piston stopper 86 backs up and at the same time moves the piston 52 further in the same direction, the squeezed compressed waste 24 is pushed by the piston 52 and the screw extruder through the steam discharge pipe 57 It falls to the inlet of the barrel 64 which comprises 60.

At this time, the compressed waste 24 dropped to the barrel 64 is injected through the channel 63a between the barrel 64 and the screw 62 by the screw 62 rotated by the screw motor 63. As it is pushed toward the side, the residual water 22 flows down to the lower drip tray 66 through the discharge hole 64a formed at the lower portion of the barrel 64.

At this time, since the outer surface of the barrel 64 is heated by the heating device 90, the moisture 22 contained in the extrusion waste 26 passing through the channel 63a between the barrel 64 and the screw 62. As it is evaporated, it is discharged to the outside through the steam discharge port 57a at the upper end through the steam discharge pipe 57, and the extrusion waste 26 is dried.

On the other hand, the water 22 dropped into the upper drip tray 55 and the lower drip tray 66 collects in the nozzle 56a while flowing through the guide pipe 56 and the branch pipe 67, respectively, and the nozzle ( 56a) is injected into the lower evaporator 70.

At this time, the water 22 sprayed downward falls inside the centrifugal dehydrator 72 constituting the evaporator 70, and when the high-speed rotation motor 72m of the centrifugal dehydrator 72 is rotated, the dehydration tank While scattering to the outside through the dehydration hole 72a formed in the 72b, the inner wall of the preheating container 74 is stuck to the inner wall, and the preheating container 74 is heated to a high temperature by the heater 76 on the outside. As soon as they stick to the water, they evaporate and fly into the air.

Then, since the bottom surface of the preheating container 74 is convex, the water 22 falling to the bottom is collected at the corner of the dewatering container 72b and the preheating container 74 and collected near the dewatering container 72b. The water 22 is scattered outward again by the rotational force of the dehydration container 72b, and the water 22 collected at the corner of the preheating container 74 is evaporated by heat.

As described above, the present invention is configured to simultaneously heat food waste while extruding food waste, so that it is possible to remove water from food waste neatly, as well as to significantly reduce the weight of food waste. Because it is in a state, it can be used immediately for compost or manure, and when it is landfilled, it can prevent the generation of leachate, and the moisture generated when compressing food waste is evaporated into the atmosphere. It is environmentally friendly because it does not contaminate sewer pipes or soil.

In addition, since the metal detector installed in the hopper so as to know the infiltration of metallic foreign matter in advance, there is an effect that can prevent the failure of the machine by the metallic foreign matter.
