Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for continuously separating citrus sac into individual grains of sand.

Recently, citrus sandbags, which have been separated into individual grains, are finding new uses in juices and cakes.

The method of removing the inner and outer skin of the fruit to obtain the sacs has already been established as a manufacturing process for canning mandarin oranges, etc., but the obtained sacs are further separated into individual grains of sand. No fully satisfactory method has yet been found.

Among physical methods that do not cause the risk of decomposing and softening the sand sac film, the method of separating the sand sac by impact from a jet of water while partially suspended in water is the preferred method as it causes the least amount of damage to the sand sac. However, some spores have unseparated endothelium attached to them, and some contain seeds.
These endothelium and seeds were deposited on the mesh of the sump that separates the unseparated yeast sacs from the separated sand sacs, and it was sometimes necessary to stop operations and remove these impurities.

This invention attempts to enable continuous operation by using a cylindrical separation net and continuously sending out these impurities to one end of the net.

A detailed explanation will be given below with reference to the drawings.

Fig. 1 shows an embodiment of the sand bag separation device of the present invention, partially shown in cross section, and 1 has a mesh size of, for example, 5M, through which only sand bags separated into individual grains can pass through. It is a cylindrical body made of net, and a propulsion screw 2 is provided inside thereof in contact with the inner surface of the net cylindrical body.

This net cylindrical body 1 is supported by rollers 4 provided on the machine stand 3 so that its lower part is submerged under the water surface of a water tank 5 provided on the upper part of the machine stand 3 so that it can be transferred.

Reference numeral 6 denotes a jet pipe, which sprays running water from its downward nozzle onto the canister on the mesh cylinder.

In this embodiment, another jet tube 7 is provided at the top of the mesh cylinder 1 to wash away the impurities that have risen with the mesh.

Further, at the outlet end of the mesh cylinder 1, an appropriate number of blades 8 for scraping up the residue are provided as shown in the cross-sectional view in FIG. is discharged to the top.

10 is a drainage container for receiving the residue, 11 is an inlet for the shogunate, 12 is an outlet for the sand bag, 13 is a drainage conveyor made of a fine mesh, 14 is a flow rate adjustment valve, and 15 is for draining the discharged water. A pump 17 for circulating the fluid from the receiving container 16 to the jet pipes 6 and 7 is a drive shaft of the mesh cylinder 1 driven by a belt or the like by a motor (not shown).

If holes such as tangerines or broken spores are put into the mesh cylinder 1 from the input port 11, the spores are partially suspended in the water as the mesh cylindrical body rotates 10 times, and are moved by the propulsion screw 2. It is sent to the left in the figure.

At this time, if a water stream is injected from above through the jet pipe 6,
The impact of the jet and the turbulent flow in the tank caused by the jet separate the grains of sand into individual grains of sand, and the separated sand immediately passes through the mesh into the tank 5 below. be carried to.

At this time, the spores inside the mesh cylinder are continuously transported by the propulsion screw, so they are uniformly impacted by the water flow regardless of the jetting position of the water flow.

Spores that were not separated into individual grains enough to pass through the mesh and endothelium that could not be peeled off in the previous process adhered to the mesh, and with conventional equipment, this had to be removed by interrupting operation. In the device of this invention, not only things that are partially suspended in the water, but also things that are attached to the net and rise up, enter the water again as the net cylindrical body rotates, are sent in one direction by the propulsion screw, and are gradually removed from the residue. and is concentrated at one end of the mesh cylinder.

Furthermore, as in this embodiment, a cleaning jet pipe 7 is provided at the top.
By providing this, unseparated spores immediately return to the separation site, which not only improves separation efficiency, but also prevents the sieving ability of the mesh cylinder 1 from decreasing due to adhesion to the mesh. .

The sand grains separated into individual grains are discharged together with water from the discharge port 12 onto the draining conveyor 13, and the water flows into the lower receiver 16.
The water flows into the interior and is returned to the jet pipes 6 and 7 by the pump 15.

As mentioned above, residues such as endothelium and seeds are removed by the propulsion screw 2k.
Therefore, the accumulated residue gradually accumulates on the left end of the mesh cylinder 1, but even if the operation of the device is stopped and the accumulated residue is removed,
The operating time can be significantly extended compared to the conventional device, by providing an appropriate number of scraping blades 8 on the left end and continuously discharging the scraped residue into the container 10 through the discharge gutter 9. Fully continuous operation is possible.

As shown in FIG. 3, a plurality of jet tubes 6 are provided to increase the separation capacity, and to prevent the residue washed by the upper jet tube 7 from accumulating on the jet tubes 6. A cover 18 is provided, an upper jet pipe 7' is provided in the horizontal position shown by the dotted line in order to quickly return the unseparated spores that rise as the net cylindrical body 1 rotates to the separation position, and the upper jet pipe 7' is provided in the horizontal position shown by the dotted line. Various design changes are possible within the scope of this invention, such as using a different device.

This invention produces the following remarkable effects with the above configuration.

1. Since the sandbags are separated in a state where they are partially suspended in shallow water, the impact on the sandbags is alleviated by the water, and the separated sandbags are immediately discharged and are not subjected to any unnecessary impact, so there is no damage to the sandbags. Less is.

2. Since the sacs are continuously sent under the jet stream by the propulsion screw, all the sacs receive uniform impact, resulting in high separation efficiency and less damage.

3. Since the mesh is constantly flushed by the upper jet stream, no clogging occurs and long-term operation is possible.

4. Residues such as endothelium and seeds are collected at one end of the net cylindrical body, making it easy to remove them, and it is also easy to remove them continuously due to continuous operation of the device.
