Abstract

PURPOSE:To drastically save time and cost for an incineration treatment by frying waste vegetables, etc., with oil. CONSTITUTION:Materials to be treated such as waste vegetables are subjected to a dehydration treatment by compression. These materials are thereafter fried with the oil and are further subjected to a crushing treatment at need. The materials are subjected to primary dehydration by compressing rolls 2 in a case 4 formed with an upper hopper 3 in a primary dehydration section 4. Next, the materials to be treated and squeezed water are supplied to a secondary dehydration section B. The materials from which the water is separated by a rotary drum 12 having many draining holes 13 in a case 11 in this section are supplied via a scraper 18 to a net conveyor 21. The materials to be treated are transferred to a frier 22 and are passed into this frier 22, by which the materials are fried with the oil and are dehydrated. The materials are passed between crushing rolls 24 at need and are thus pulverized to fine particles.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for dehydrating waste vegetables, and more particularly, containing a large amount of water such as bean sprouts, okara, and seafood, which are discarded in large quantities in food factories. The present invention relates to a method and an apparatus for dehydrating waste vegetables such as waste vegetables, which are dehydrated prior to incineration for easy incineration.

[0002]

2. Description of the Related Art In a food factory, especially a factory handling fresh food such as vegetables and seafood, many tons of vegetables and seafood, such as sprouts, should be disposed of in a lot of places every day. Get out. Conventionally, these discarded vegetables have been used as feed for livestock, but recently they have been incinerated without being used as such. Since waste vegetables have a high water content, they are dehydrated before being incinerated. As a conventional dehydrator, a crusher that shreds and crushes waste vegetables
It is known to have a screw type dehydrator.

[0003]

In the case of the above-mentioned conventional dehydrator, the dehydrating function cannot be said to be sufficient, the waste is bulky even after the treatment, and much waste is caused by the incineration treatment which is an unproductive act. Result in spending a lot of time and money. Therefore, the present invention has a simple structure, can be supplied at low cost, and has an excellent dehydration function, and can incinerate with a small amount of energy, thereby significantly reducing the processing time and cost of waste vegetables and the like. It is an object of the present invention to provide a method and an apparatus for dehydrating waste vegetables and the like, which is excellent in energy saving effect and can be brought down to the full.

DISCLOSURE OF THE INVENTION The present invention relates to a method for dehydrating waste vegetables, characterized in that the object to be treated is dehydrated by pressing, then fried, and further crushed if necessary.
Or, a pair of deformed rolls having a shape in which a bulged portion having a semicircular cross section and a shallow dent are alternately formed, and a bulged portion of one roll faces a dent of the other roll, and A compression roll formed by arranging both rolls so that they rotate inward at the same speed,
A water-permeable rotation, which is supported below from the inside of the pressing roll by a receiving roll and a supporting roll that are in contact with the inner surface, and is rotatably driven by being held between the receiving roll and the driving roll. From a drum, a net conveyor connected to the rotary drum, an intermediate portion of which is configured to be able to pass through the flyer, and a holding conveyor which is attached to the net conveyor and circulates in the opposite direction to the net conveyor. The above-mentioned problem was solved by using a dehydration processing apparatus for waste vegetables.

[0005]

[Operation] The object to be treated is first squeezed by passing through the squeezing roll to be primarily dehydrated. At that time, one surface of the object to be treated abuts on the bulge of one of the deformed rolls, The other surface abuts the recess of the other profile roll. Since the bulging portion and the depression have different rotational radii and thus different peripheral velocities, the object to be processed is deviated from its front and back sides, and as a result, water is leaked out and good dehydration is performed. The object to be processed falls on the rotating drum, is conveyed as the rotating drum rotates, and is driven and driven.
When passing through the portion of the roll, a pressure is applied between the drive roll and the rotating drum, and water is further squeezed out. After that, while being dropped on the net conveyor and conveyed, it is almost completely dehydrated by being fried in a fryer.
At that time, since it contains oil, it can be efficiently incinerated thereafter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment 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 which 1 is a supply conveyor for supplying an object to be processed such as waste vegetables to the apparatus, and a primary dewatering section A is provided below a tip portion thereof. Will be deployed. The primary dehydration section A has a hopper at the top.
3 is composed of a pressing roll 2 installed in a case 4 forming the same.

The squeeze roll 2 has semi-circular bulging portions 5 having three cross-sections, and the irregular shaped rolls 7 each having a shallow recess 6 between the bulging portions 5 are placed opposite to each other. -The bulging portion 5 of the roll 7 is arranged so as to face the recess 6 of the other variant roll 7 at a predetermined interval. Gears meshing with each other are fixed to the shaft ends of the deformed rolls 7, so that both rolls always rotate inward at the same speed.

The bottom of the case 4 is opened, and the object dehydrated in the primary dewatering section A and the squeezed water fall from the opening section 8 and the secondary dewatering section installed below it. Supplied to B. The secondary dehydration section B comprises a box-shaped case 11 and a rotary drum 12 therein. The rotary drum 12 is provided with a large number of drainage holes 13 through which water squeezed out can escape.

The rotary drum 12 is in contact with the inner peripheral surface thereof, and is normally supported in a fixed position by two receiving rolls 14 and two supporting rolls 15, respectively. And the receiving roll 1
The rotary drum 12 is rotationally driven by the rotation of the drive rolls 16 and 16 which are provided in opposition to the receiving rolls 14 and 14 and press the rotary drum 12 between them. Drive low
The motors 16 and 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 installed just below the opening 8 on the upper surface of the case 11 so that the falling object to be processed is guided onto the rotary drum 12.
That is, the opening 8 is normally located at the rear of the rotating drum 12 in the rotational direction (to the right in FIG. 1) so that the falling water falls to the rear of the rotating drum 12 in the rotational direction. A guide plate 17 is provided in order to prevent an object from falling backward together with water.

Reference numeral 18 is a squeeper which is arranged with its upper end in front of the rotary drum 12 (to the left in FIG. 1), and which serves as a casing for the workpiece to be dropped along the rotary drum 12. It is discharged out of the space 11. The lower end of the squipeper 18 is located on the end of the net conveyor 21. The net conveyor 21 is a flyer in which the middle part is depressed downward.
Immerse in 22.

A holding conveyor 23 is additionally provided on the net conveyor 21 at an appropriate interval to prevent the object to be processed from floating in the flyer 22. Presser conveyor 23
Circulates in the opposite direction to the net conveyor 21. Reference numeral 24 denotes a pair of crush rolls, which are arranged below the advancing end of the net conveyor 21.

In the above-mentioned structure, the object to be treated such as waste vegetables, which has been put into the hopper-3 from the supply conveyor 1, falls and is caught between the deformed rolls 7 and 7 which rotate inward. To be done. By the way, the deformed rolls 7 and 7 always rotate so that the bulging portion 5 of one roll and the dent 6 of the other roll face each other. Since the distance from is different, the peripheral velocities on 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.

Therefore, the traveling speeds are different between the front and back surfaces of the object to be processed, one surface of which is in contact with the bulging portion 5 and the other surface of which is in contact with the depression 6, and the object is not simply pressed. However, the displacement is caused on the front and back surfaces, and the tissue is destroyed. Therefore, the volume of the object to be treated can be reduced (1/5 to 1/10) and sufficient dehydration can be achieved. For example, in the case of bean sprouts, the initial water content is about 90% to about 20%.

The object to be treated, which has been compressed by the compression roll 2, falls from the opening 8 and is conveyed, guided by the guide plate 17 and mounted on the rotary drum 12, and one or two drive rolls are installed. Pass under Le 16. At this time, the object to be treated is pinched between the drive roll 16 and the rotary drum 12, and is further dehydrated while being spread. Water that has been squeezed out is a drain hole 13
Falling through or through the rotating drum 12. After that, the object to be processed falls along the squeeper-18, falls on the net conveyor 21, and is conveyed. An object to be processed that is in close contact with the rotary drum 12 is a squeeper-18.
Stripped by.

The object to be processed conveyed by the net conveyor 21 is deep-fried and dehydrated by passing through the flyer 22 on the way, and is discharged in a state that it contains oil and is extremely easy to burn. The object to be processed during passing through the fryer 22 is pressed by a pressing conveyor 23 that circulates so that the lower side is in the same direction as the direction of travel of the object to be processed, so that it does not float from the net conveyor 21 and is reliably fried. At the same time, it continues to be transported.

The object to be processed which has been emptied after passing through the fryer 22 can be further crushed into particles by passing through a crushing roll 24, if necessary, so that it can be more easily burned. In order to further save energy, it is preferable to use combustion heat of the object to be processed as a heat source of the flyer-22.

[0018]

As described above, the present invention is capable of performing a series of steps or devices from the introduction of an object to be processed to the combustion process, and a squeezing roll in which variant rolls are combined.
Sufficient dehydration treatment can be performed by the primary dehydration unit composed of a roll and the secondary dehydration unit composed of a drive roll and a rotary drum. In addition, by performing such dehydration treatment, frying treatment, and further crushing treatment, almost complete dehydration can be achieved, thereby significantly reducing the time and cost of incineration treatment and contributing to energy saving. .
