Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a dehydrator in the production of foods such as cut vegetables, and in particular, it accommodates and spins dehydrated objects such as sterilized and washed cut vegetables. The present invention relates to a rotary container that dehydrates by centrifugal force.

[Conventional technology]

In recent years, in fresh food counters such as supermarkets, cabbage, Chinese cabbage, carrots, burdock, etc. are sterilized and washed, cut into a shape suitable for cooking, washed with water and dehydrated, then weighed and removed in a plastic bag. You can see the cut vegetables that have been wrapped in air.

This cut vegetable is manufactured by the manufacturing apparatus 1 as shown in FIG. 4 through a consistent process from washing / cutting of raw vegetables to deaeration packaging. The processed unprocessed raw material vegetables are sterilized and cleaned in the sterilization tank 5 and the cleaning tank 6 through the raw material cleaning tank 4, and then sent to the slicer 7 to be cut into a predetermined shape.

After the cut vegetables cut by the slicer 7 are washed in the second washing tank 8, they are sent to the dehydrator 10 by the conveyor 9 to be dehydrated, and further sent to the weighing machine 12 by the conveyor 11 to be weighed, It is deaerated and packaged in the packaging machine 13.

The packed cut vegetables are sent to the weight checker 15 and the sorting machine 16 by the conveyor 14, and are packed in a cardboard container by the cardboard caser 17.

The dewatering device 10 has a structure such as a household washing machine, and when a substance to be dehydrated is put in, a net bag is provided in a rotary container in advance, and the dewatering work is performed while the substance to be dehydrated is stored in the net bag. Be done.

Then, after the dehydration, the rotation of the rotary container was stopped and the net bag containing the substance to be dehydrated was taken out.

[Problems to be solved by the device]

However, in the above-described dehydrating device, it is necessary to obtain the mesh bag for handling, and therefore, although it is possible to perform unmanned in other steps, an operator is required for the dehydrating work, and there is a high demand for complete automation. It was

Incidentally, when the substance to be dehydrated is automatically carried into the rotary container, the efficiency of dehydration is poor unless it is carried out so as to be substantially uniform on the inner circumference of the rotary container. This is also a technical problem in automation.

The present invention aims to save labor by automating the above-described dehydration work, and at the time of rotating the rotating container, the dehydrated objects such as cut vegetables are loaded substantially evenly on the inner circumference of the side wall of the rotating container, so that It is an object of the present invention to provide a rotating container for a dehydrating device, which maintains the rotational balance and improves the dehydrating ability.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention secures a rotary container having a large number of drainage holes formed in a cylindrical side plate to a rotary shaft that is erected in a casing, and performs a cleaning process on the rotary container driven by the rotary shaft. In the dehydrator that performs the dehydration process by feeding the already dehydrated material and rotating the rotary container at a high speed, the rotation axis can be switched to a low speed in order to automatically perform the insertion and removal of the dehydrated material, An elevating device for elevating the bottom plate of the rotary container is connected to the rotary shaft, and a cone protruding upward is provided at the center of the bottom plate.

[Action]

According to the above configuration, the object to be dehydrated in the rotating container is dehydrated at high speed, and then the bottom plate on which the object to be dehydrated is lifted in the side plate of the rotating container switched to low speed rotation. The water to be dehydrated on the bottom plate rotating at a low speed is discharged from the upper part of the rotating container.

Further, the dehydrated substances such as cut vegetables placed in the rotating container rotating at a low speed fall on the cone on the bottom plate, and are further scattered by the centrifugal force of the rotation, and are evenly loaded on the inner peripheral surface of the side plate. It
