[0005]

[Work] First, an object to be processed is squeezed by passing through a pressing roll to be primarily dehydrated. At this time, one surface of the object to be processed comes into contact with the bulging portion of one of the deformed rolls. The other surface abuts the depression of the other deformed roll. Since the swollen portion and the dent have different rotational velocities due to different rotational radii, the object to be processed is shifted in its front and back sides, and as a result, water is oozed out and good dehydration is performed. The object to be processed falls on the rotating drum, is conveyed with the rotation of the rotating drum, and is driven by a driving roller.
During the passage through the roller portion, the pressure is held between the driving roll and the rotating drum, and the water is further squeezed out. Thereafter, while being conveyed after being dropped on the net conveyor, it is almost completely dewatered by being fried in a fryer.
At that time, since it contains oil, it can be efficiently incinerated thereafter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an overall configuration diagram of an apparatus according to the present invention. In FIG. 1, reference numeral 1 denotes a supply conveyor for supplying an object to be processed, such as waste vegetables, to the apparatus. Be deployed. The primary dewatering section A has a hopper
It is composed of a pressing roll 2 installed in a case 4 forming 3.

The pressing roll 2 has a semi-circular bulging portion 5 having three cross sections, and a deformed roll 7 having a shallow dent 6 between the bulging portions 5 is opposed to one another. The bulging portion 5 of the roll 7 faces the recess 6 of the other deformed roll 7 at a predetermined interval. Gears meshing with each other are fixed to the shaft end of each deformed roll 7, so that both rolls always rotate inward at the same speed.

The bottom of the case 4 is opened, and the object to be treated and the squeezed water which have been primarily dehydrated in the primary dehydrating section A fall from the opening 8 and are placed under the secondary dehydrating section. B. The secondary dewatering section B comprises a box-shaped case 11 and a rotating drum 12. A large number of drainage holes 13 are provided in the rotating drum 12 so that water squeezed out from the surface can be drained.

The rotating drum 12 is in contact with the inner peripheral surface thereof, and is supported at a fixed position by a receiving roll 14 and a supporting roll 15 which are usually provided two each. And receiving roll 1
The rotary drum 12 is driven to rotate with the rotation of the drive rolls 16, which are provided opposite to the rolls 4, 14 and press the rotary drum 12 between the receiving rolls 14, 14. Drive row
The motors 16, 16 are driven to rotate in the same direction at the same speed by a motor (not shown). The receiving roll 14 and the supporting roll 15 rotate freely.

An inclined guide plate 17 is provided directly below the opening 8 on the upper surface of the case 11 so that the object to be dropped is guided onto the rotating drum 12.
That is, the opening 8 is usually located rearward in the rotational direction of the rotary drum 12 (to the right in FIG. 1) so that falling water falls rearward in the rotational direction of the rotary drum 12. A guide plate 17 is provided to prevent the object from falling backward with the water.

Reference numeral 18 denotes a squeeze radiator arranged with its upper end attached to the front (left side in FIG. 1) peripheral surface of the rotary drum 12, and a case for treating an object falling along the rotary drum 12. To the outside of the source 11. The lower end of the squeeze wrapper 18 is located on the end of the net conveyor 21. The net conveyor 21 has a middle part recessed downward, and a flyer.
22.

A holding conveyor 23 is provided on the net conveyor 21 at an appropriate interval to prevent the workpiece from floating in the flyer 22. Presser conveyor 23
Is circulated in the opposite direction to the net conveyor 21. Reference numeral 24 denotes a pair of crushing rolls, which are arranged below the traveling end of the net conveyor 21.

In the above-mentioned construction, the objects to be treated such as discarded vegetables and the like put into the hopper 3 from the supply conveyor 1 fall between the irregularly shaped rollers 7, 7 which rotate inward, and are caught and pressed. Is done. By the way, the deformed rolls 7, 7 always rotate so that the bulging portion 5 of one roll and the dent 6 of the other roll face each other. Because the distance from the surface is different, the peripheral velocities of the surfaces of both parts are also different. That is, the peripheral speed is higher on the surface of the bulging portion 5 having the longer distance.

Accordingly, the traveling speeds of the front and back surfaces of the object to be processed, which one surface is in contact with the bulging portion 5 and the other surface is in contact with the depression 6, are different from each other. Instead, a shift is induced on the front and back surfaces, and tissue destruction occurs. Therefore, the volume of the object can be reduced (1/5 to 1/10), and it is possible to sufficiently dehydrate the object. For example, in the case of sprouts, the initial moisture content is reduced from about 90% to about 20%.

The object to be processed squeezed by the squeezing roll 2 falls from the opening 8 and is conveyed, guided by the guide plate 17 and rides on the rotary drum 12, and one or two driving rolls are provided. Pass under the rule 16. At this time, the object is clamped between the drive roll 16 and the rotary drum 12, and is further dehydrated while being spread. The squeezed water is drained 13
Or fall along the rotating drum 12. The object to be processed thereafter falls along the squeeze wrapper 18, falls onto the net conveyor 21, and is conveyed. The processing object in close contact with the rotating drum 12 is
Stripped off by

The material to be processed conveyed by the net conveyor 21 is fried and dehydrated by passing through the flyer 22 on the way, and is discharged in a state that it contains oil and is very easily combusted. During the passage through the flyer 22, the object to be processed is pressed by the pressing conveyor 23 circulating so that the lower side thereof is in the same direction as the direction of the object to be processed. , And continue to be transported.

The material to be processed which has passed through the flyer 22 can be further crushed by passing it through a crushing roll 24, if necessary, to make it more flammable. In order to further save energy, it is preferable to use the heat of combustion of the object to be processed as the heat source of the flyer 22.

[0018]

As described above, the present invention is capable of performing a series of steps or equipment from the charging of the object to be treated to the burning treatment, and a pressing roller combining deformed rollers.
Sufficient dehydration processing can be performed by the primary dehydration unit composed of a roller and the secondary dehydration unit composed of a driving roll and a rotating drum. In addition, after performing such a dehydration treatment, a frying treatment is performed, and further a pulverization treatment is performed, so that almost complete dehydration can be performed. As a result, the time and cost of the incineration treatment can be significantly reduced, and the effect of contributing to energy saving can be obtained. .
