Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveying device for conveying a granular material containing water, such as squeezed fruit juice and tea powder extracted from tea.

[0002]

2. Description of the Related Art In recent years, fruit juice and various teas are bottled or canned and sold in large quantities. In the production of these beverages, a large amount of granules such as squeezed juice obtained by squeezing fruit juice and tea leaves extracted from tea are discharged, and the transportation of the granules is a major problem in production. These dregs contain a large amount of water and are heavy. In the past, these debris discharged from the hopper were placed on a transport vehicle and collected at a collection site, where they were loaded into a large vehicle and transported to a disposal site.

[0003]

However, according to the above-mentioned transportation means, it is necessary to prepare a large number of transport vehicles, and also an operator who operates the transport vehicles is required. There is a problem that it takes time. It is conceivable to lay a belt conveyor from the hopper to the gathering place, but since the distance between the two is long, a new problem arises that a large amount of equipment cost is required.

Conventionally, the transportation of objects by air is generally applied to dried powder or granules. However, as a result of diligent research, the applicant is able to pneumatically transport even granular materials such as squeezed juice obtained by squeezing fruit juice and tea powder extracted from tea by reducing the water content to an appropriate range. It was confirmed. The present invention has been made in view of the above circumstances, and an object thereof is to easily convey a granular body containing water, and further, the equipment cost can be reduced, and to convey the granular body containing water. To provide the equipment.

According to a first aspect of the present invention, there is provided a transporting device for transporting a granular material containing water such as squeezed fruit juice and tea powder from which tea is extracted. It is characterized in that it is provided with a dehydrating section for dehydrating the water of 1. and a conveying section for pneumatically transporting the dehydrated granular material. According to a second aspect of the present invention, the dewatering unit includes a screw that conveys the granular material, a casing that surrounds an outer peripheral portion of the screw,
It is characterized in that it has a water passage hole formed in the lower surface portion of this casing.

[0005]

According to the invention of claim 1, the water-containing granules such as squeezed juice from juice and tea leaves from which tea has been extracted are dehydrated in the dehydration section, and the water content thereof is suitable for pneumatic transportation. Reduce to a state. Therefore, if the dehydrated granular material is transported by air, the transportation of the granular material can be facilitated and the facility cost can be reduced. In the dewatering section of the invention of claim 2, when the granular material is conveyed by the screw, the granular material is compressed between the screw and the casing, water is squeezed out and discharged from the water passage hole.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The hopper 1 is installed below the beverage manufacturing machine 2, and granules containing water such as squeezed residue obtained by squeezing fruit juice and tea scraps from which tea is extracted are charged from the charging port 1a at the upper part, and the discharging port 1b at the lower part It is connected to the dehydration unit 3. The dewatering unit 3 is composed of a so-called screw conveyor, and includes a screw 4 that conveys the granular material, a casing 5 that surrounds the outer periphery of the screw 4, and a plurality of passages that are formed on the lower surface of the casing 5. And water holes 6.
A drain 7 is provided below the casing 5 to collect water dehydrated from the granular material.

[0007] The powdery granules such as the squeezed residue obtained by squeezing the fruit juice discharged from the beverage production machine 2 and the tea powder extracted from the tea are usually about 6
Although the water content is 0 to 70%, it is pumped by the screw 4 when passing through the dehydration section 3, the water content is squeezed out, collected in the drain 7 and discarded. And, the water content of the granular material is about 5 to 15% after being dehydrated to about 45 to 55.
%.

The dehydrated granular material is put into a hopper 11 and sent to a pressure feeding pipe 13 via a rotary valve 12. This pressure-feeding pipe 13 connects between the hopper 11 and the residue hopper 14 provided at the stacking place.
3, compressed air is supplied from an air compressor 15 such as a roots blower, and the flow velocity of the air in the pressure feed pipe 13 is 10
It can be adjusted to a range of up to 50 m / s, and a flow velocity of 30 to 35 m / s is usually used. Then, the pressure-feeding pipe 13 and the air compressor 15 constitute a carrying unit 16.

The granular material sent through the pressure feeding pipe 13 is accumulated in the dust hopper 14. And the lower door 14a
When is opened, it is loaded into the vehicle 17 for unloading. An air blow (not shown) is attached to the dust hopper 14 in order to accelerate discharge of dust left on the inner wall. Also,
An operation panel 18 for controlling each device is installed.

The dewatering section is not limited to the above-mentioned embodiment, but may be, for example, a centrifugal type, and the granular body dehydrated by this centrifugal type dewatering machine is a separate unit. You may convey to the hopper 11 by a conveying apparatus.

According to the above-mentioned embodiment, even the granular particles containing water such as squeezed juice obtained by squeezing fruit juice and tea powder extracted from tea are dehydrated to a predetermined water content by the dehydration section 3, so that they are transported by air. This makes it possible to easily convey the granular material by installing the pressure feed pipe 13 and the air compressor 15 even if the place where the dust is collected is distant.
Further, unlike the conventional case, it is not necessary to prepare a large number of transport vehicles and it is not necessary to lay a belt conveyor over a long distance. Therefore, it is possible to significantly reduce the facility cost as compared with the conventional case. Is played. Further, since the dehydrating section 3 is composed of the screw 4, the casing 5 and the water passage hole 6, the granular body can be dehydrated while being conveyed, and the work can be efficiently performed. Moreover, the dehydration unit 3
Has the effect that the equipment cost can be further reduced because it is used both as a dehydrator and a conveyor.

[0012]

According to the first aspect of the present invention, there is provided a transporting device for transporting water-containing granules such as squeezed juice obtained by squeezing fruit juice and tea scraps obtained by extracting tea. Since it is equipped with a dehydrating section for performing dehydration and a transporting section for transporting the dehydrated granular material by air, the dehydration section enables dehydration to a predetermined water content, which enables air transportation, and a place where dust is collected is far away. Even with the effect of being able to easily convey the granular material simply by laying a pressure feed pipe and an air compressor, it is possible to significantly reduce the equipment cost compared to the conventional one. is there.

According to a second aspect of the present invention, the dehydrating section includes a screw for conveying the granular material, a casing surrounding the outer peripheral portion of the screw, and a water passage hole formed in a lower surface portion of the casing. Therefore, the granular material can be dehydrated while being transported, and the work can be efficiently performed. Moreover, since the dewatering device and the transfer device are used in combination, the facility cost can be further reduced.
