DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a raisin cleaning apparatus. Raisins are mostly imported in our country.
Imported raisins cost 30 pounds (13.6k
g) pressed in a plastic bag weighing 30 g
It is packaged in a corrugated ball with a size of 0x270x200 as a nearly unified standard, and is stacked in multiple stages and loaded. The raisins unpacked and unloaded are very loose, as the glucose deposited from the raisins binds the raisin grains together and continues to be compressed while being pressed and loaded. It forms a mass of bones. Furthermore, even if such a raisin mass is loosened, such raisins cannot be used in breads, cakes, confections, etc. as they will contain garbage adhering to the precipitated glucose. .

[0002]

2. Description of the Related Art Raisins have been loosened and washed by hand. The bakery and confectionery industry, which uses a large amount of imported raisins, has been forced to use a lot of labor to unravel and clean the raisins, even though it is merely a preparatory process for preparing ingredients. How to simplify the task has been a long-standing challenge. Therefore, the present inventor has previously sent a raisin or the like into a liquid cyclone along with a strong water stream, and guided the water stream containing the raisins that came out into the rotating hexagonal mesh-shaped columnar body to perform raisin washing, a `` dry fruit selection device ''. It is being developed (JP-A-63-158142).

[0003]

However, as described above, raisins are washed in a state where the precipitated glucose is collected together with the attached garbage, and in a state where the raisin grains are combined with each other to form a tick. Since it is washing things, it is necessary to have a skillful combination of loosening that does not destroy raisins and washing with enough water to dissolve glucose to some extent. Since the sugar is substituted and loses the umami and may be swelled, it is further required that the washing be performed efficiently in a minimum time. In addition, as described above, for bakery and confectionery, raisin washing is only a preliminary treatment for preparing some ingredients, so it is not economically preferable to use a large-scale apparatus for this, and it is more convenient and efficient. Equipment is required. For the reasons described above, the present inventor has continued to develop an apparatus more suitable for raisin cleaning than the above-mentioned selective apparatus completed as a result of many years of research, and as a result, completed the present invention. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS Raisin loosening apparatus, cleaning apparatus,
Specific examples of these combination devices (hereinafter simply referred to as cleaning devices) will be described in more detail with reference to the drawings.

As shown in FIG. 1, the cleaning apparatus comprises a raisin inlet 1, a water injection nozzle 2, a loosening means 3, a stirring water washing zone 4, a draining dust crushing zone 5, and an outlet 6.

The water injection nozzle supplies water to the mass of raw raisins falling on the loosening device, but the water supply amount is minimal in the device of the present invention.

As shown in FIG. 3, the unraveling device 3 is provided in a vertical raw material raisin passage 30 immediately below the raw material raisin input port 1, and is provided with a pair of counter-rotating counter-rotating wheels located at the same height. It has a rotating shaft 31 and a fixed shaft 32 located between the rotating shaft and slightly below the rotating shaft. The pair of rotating shafts 31 have four round bars 33 radially protruding at an angle of 90 degrees at a plurality of positions at substantially constant intervals throughout the entire passage 30. The fixed shaft 32 has, at each position corresponding to the middle of the mounting position of the round bar 33 of the rotary shaft 31, two round bars 34 projecting substantially horizontally in opposite directions. Four round bars 33 of the rotating shaft 31 and two round bars 34 of the fixed shaft 32
Has a length sufficient to be alternately located in the gap of the other party. By rotating the one rotating shaft 31 and the other rotating shaft 31 in opposite directions to each other, the raisins that have fallen on these are collected toward the middle between the rotating shafts and fixed to the rotating shaft 31. Shaft 32 and these round bars 3
The small gap formed by 3 and 34 is forced downward through the raisin mass.
With the structure like the loosening device of the present invention, the raisins have elasticity, so that even if the lumps are crushed, the raisins themselves are not damaged.

This loosening device has a function of receiving the falling raisin lump by the round bar 33, a loosening operation of the round bar 33, a pushing action of the rotating shaft 31 and the round bar 33 to the center and below, By skillfully combining the sieving action in the gaps formed by the round bars 33 and 34, the delicate work required to unravel the raisin lump is accomplished in one simple step.

As shown in FIGS. 3 and 4, two of the round bars 33 of the rotary shaft 31 forming 180 degrees are formed by one round bar penetrating the rotary shaft 31, and the other two are formed by the rotary shaft. When the round bar 33 is attached to the rotating shaft 31 by shifting it by 2 mm in the opposite direction in the axial direction of the rotating shaft, the round bar 33 can reduce idle rotation when the raisins are loosened. I can do it.

In the stirring water washing zone 4, the same shaft 41 extending to the shaft of the draining dust hitting zone extends. A plurality of stirring blades 42 are mounted on the shaft 41. The blade of the stirring blade 42 has an optimum angle with respect to a plane perpendicular to the central axis, for example, an angle of 45 degrees, in order to generate a water flow in the direction of the draining zone where dust is blown off. In the agitated washing zone 4, since the raisins that have fallen into lumps from the lump and fall down are supplied with a small amount of water from the water injection means 2, the raisins are substantially the same as the raisins immersed in water. It is in the state of. Then, since the stirring is performed by the stirring blades 42, a part of the glucose and garbage deposited on the raisin surface are washed with water and dissolved or suspended therein. With such a configuration, the stirring water washing zone 4 has an action of stirring and washing a part of glucose and dust on the raisin surface, and an action of dumping a mixture of water and raisin and draining the dust to the zone 5 as a mixed water / raisin stream. It is performed simultaneously and continuously.

The draining dust removal zone 5 is provided with a central shaft 51 and four splashing blades 52 attached to the shaft 51. The angle of the blades 53 of the splash blades 52 with respect to a plane perpendicular to the shaft 51 is gradually reduced or made constant toward the outlet 6. The splashing blades 52 splash raisins, water, and debris, rotate the basket at high speed in the circumferential direction and move in the exit direction, during which water and debris are discharged out of the gap of the cylindrical basket 8. When only the raisins hit the peripheral surface of the cylindrical basket 8, the raisins rebound and advance toward the exit. The raisins are thus separated from the water and the debris. In order to limit the circumferential slip of the mixture of raisins and water to some extent due to the collision with the raisins and to obtain a sufficient time for knocking garbage from the raisins, there are a large number of barrier surfaces which are the peripheral surfaces of the cylindrical basket 8. And a number of barriers, which are arranged in a direction substantially parallel to the axis. Preferably, the peripheral surface is formed by a large number of 3 mm thin metal rods arranged at regular intervals in parallel with the central axis of the basket, for example, at a pitch of 3 mm. With such a configuration, water is dehydrated quickly and without stopping the movement of the raisins in the direction of the raisins from the raisins substantially immersed in the water, and the garbage that has adhered is simultaneously removed from the raisin surface. , And wash out of the band. It should be noted that, although the raisins are in the same condition as the raisins are substantially immersed in the water in the agitated washing zone 4, the same level of the draining smashing zone 5 is continuously mixed with the trash. The water is separated and the raisins are dehydrated near the outlet.

[0022]

[Effects of the present invention] The effects of the present invention are as follows: 1) The apparatus is simple and the cost is low. 2) From the injection of raisin chunks to the separated raisin grains that have been washed, in particular, from washing and dissolution of glucose to dehydration, can be carried out as a single stream continuously and in a short time. There is no need to separately install expensive equipment. 3) Since the raisins can be washed in a short time, the taste of the raisins is not lost.
