Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is mainly used for bleaching and pre-dehydration of fish meat in the process of producing surimi, and for removing fine particles of fish meat contained in the water-bleached wastewater. This relates to collection, etc.

Conventional technology For example, the rotating sieve used for making surimi is made of a nylon mesh with a Y-shaped mesh, which can easily break, and when a wire mesh with a 1-mesh mesh breaks, the wire can get into the material. For reasons such as being dangerous, conventionally we have used a material with a large mesh at the worn end and a board thickness of 7.

As a result of the above, since the mesh is large, fine particles of fish meat flow out together with the wastewater, resulting in poor yield of surimi and generally making wastewater treatment difficult.

Problems to be Solved by the Invention Conventional rotary sieves for producing surimi use punched nets with a plate thickness that is not easily damaged and has a mesh that is worn out, but fine particles of fish meat flow out and reduce yield. The reality is that there is no suitable method to recover these fine particles, and valuable protein resources are wasted, resulting in problems in subsequent wastewater treatment.

Therefore, this machine provides a separator that attempts to collect the fine particles of fish meat flowing out from the rotating sieve using a net with a mesh that is most suitable for collecting the fine particles.

Means to Solve the Problem The present invention uses a net with a mesh size of I from the beginning depending on the fish species in order to prevent fine particles of fish meat from flowing out, and uses a cradle-type separator instead of a rotating sieve. The water is separated from the fine particles of fish meat by passing through appropriate guide plates one after another at an appropriate slope.

In addition, the fine particles of fish meat in the waste water discharged from a general rotating sieve are collected using a basket-type separator using a mesh net with a mesh size of 1.5 mm, which is suitable for fish meat. You can use a mesh net. In addition, the swing width of the cradle is appropriately adjusted depending on the data, and the slope from the entrance to the exit of the cradle is also appropriately adjusted to achieve the most efficiency.

Function In the above, set the oscillation width of the cradle, set the trough-shaped frame with an appropriate downward slope from the entrance to the exit, move the dowel-shaped frame from side to side, and place the material on the high side of the trough-shaped frame. When the material is inserted between the information board and the information board of the store, it moves step by step between the information boards as it shakes, separating the material into the material that comes out through the mesh of the net and the material that remains on the net. Move and go. In that case, if it is better to wash the net with a fountain, wash it from the bottom of both the left and right sides of the trough-shaped frame, depending on the material.
Washing water is sprayed from the lower part of the central shaft to both the left and right sides, or depending on the material, water is sprinkled to expose the material, and eventually the separated material falls down from the droplet and is collected. An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, the semicircular trough-shaped frame has a diameter of 14°1 to 1
The net that can be easily bent is 2, the net frame attached to the trough-shaped frame is 3, the frame of the semicircular guide plate is 4, the guide plate 5, the extortion rod 6, and the extortion rod on the motor side. It consists of a bottle 7, a pin 8 on the cradle side, a central shaft 9, a drainage tank 1, and a reduction motor n.

When the above speed reducer motor n is given rotation, the rotating plate 12
From the prime mover side bin 7 attached to the
At the bottle 8 on the cradle side through the semicircular trough-shaped frame 1
swings from side to side. A net frame 3 is attached to the semicircular trough-shaped frame, and together they form the framework of this far corner, which swings from side to side together with the central shaft 9. A net 2 with a mesh size of 1 mm to 1 mm is stretched over the inner peripheral surface of the mesh frame 3 that forms the frame of the cradle. Since it is made of a textile fabric, a thin punched board, etc., and has a weak stiffness, it is supported by a strong mesh frame 3 and can be mounted on the inner peripheral surface without creating too much unevenness. A semicircular guide plate 5 is placed on the net 2 together with the frame 4 of the semicircular guide plate to prevent deformation of the net 2 and to apply a concentrated load to a part of the net 2. In order to prevent this, the net frame 3 passes smoothly between the guide plates 50 and the tip of the guide plate 5 each time it swings, and moves toward the exit. The net for the mesh frame 3 is generally a wire mesh with a mesh size of 2 to 30 mm, but a punched steel plate or the like with a hole diameter of 2 to 20 mm may also be used, and both are integrated with the trough-shaped frame 1. As mentioned above, this is the framework of the cradle separator. It goes without saying that the contact portion of the guide plate 5 with the net 2 should be covered with a soft material such as rubber to prevent the net from being damaged. Also, net frame 3
It goes without saying that the contact area between the net 2 and the net 2 should be rounded so as not to damage the net 2, and recently it seems possible to use a rounded mesh frame made of resin that will not cause scratches.

The net 2, which has a mesh size of 100 to 1 mm, can be freely and easily replaced depending on the material. That is, when the guide plate frame 4 is removed, the guide plate frame 4 and the guide plate 5 are integrated, so in the illustration, the guide plate frame 4 is 180 mm.
When turned once, the guide plate frame 4 is removed. Therefore, remove the net 2, replace it with a suitable net, attach it to the trough-shaped net frame 3, place the guide plate frame 4 on top of it, and place the guide plate frame 4 on top of it.
It is preferable to attach it to the thorn-shaped mesh frame 3.

Generally, the trough-shaped mesh frame 3 has a downward slope from the entrance to the exit, but depending on the material, the material moves toward the exit each time it is pushed and shaken by the materials being thrown in one after another. In some cases, it is not.

Generally, the guide plates 5 are arranged at equal intervals, but if the materials to be separated are easily separated, the intervals between the guide plates 5 on the entrance side may be widened and gradually narrowed as they approach the exit. be.

The trough-shaped mesh frame 3 may be long depending on the material to be separated, or may be short.

Since the mesh of the net 2 is small, the material to be separated may become clogged and the mesh becomes blocked, so it is preferable to spray washing water from the pipe 13 for washing. As for the cleaning method, it is also possible to use a solenoid valve, a timer, etc. to spray a fixed amount of water at a fixed time as a water-saving method.

Alternatively, high-pressure air may be used for cleaning, and the mesh of the net may be cleaned with air.

In addition, when it is necessary to expose materials to water, a shower pipe 14 can be provided below the rotary shaft 9 to perform a shower.

Normally, on a rotating sieve with a diameter of 400 mm or more, it is difficult to install a net with a small mesh size of about 7 mm, and it is also difficult to replace the net when it is damaged.However, the cradle separator of the present invention can be easily replaced, and the guide plate The intervals between the two can also be cleaned very easily.

The swing angle of the cradle becomes smaller when the position of the bottle 7 attached to the disc 12 attached to the deceleration motor 11 is moved to the center of the disc 12, and when it is moved farther away, the swing angle of the cradle becomes smaller. Since the swing angle increases, the swing angle of the cradle can be adjusted by changing the position of the bin 7. Alternatively, this can be changed by moving the bin 8, but it is generally better to move the bin 7.

The number of times the cradle sways varies depending on the diameter of the semicircle, but generally it is around 5 to 50 reciprocations per minute; if it is too fast, various problems may occur due to centrifugal force, which is not good.

The rocking angle of the cradle should be between 10 degrees and 10 degrees.

The semicircular shape of the trough-shaped frame may be a U-shape or a triangular shape with a pointed bottom.

The guide plate 5 of the guide plate frame 4 has semicircular strip plates arranged at right angles along the inner peripheral surface so that the left and right sides engage with each other alternately.
The guide plate 5 may be arranged at right angles to both the left and right sides of the trough-shaped frame, or the tip of the guide plate 5 may be inclined toward the exit so that materials between the guide plates can be easily moved.

Depending on the material to be separated, the central axis may not be located at the center of the inner circumferential surface of the approximately semi-circular proboscis frame, but may be set at a somewhat eccentric position and swayed irregularly.

In the above configuration, for example, if the fish meat in the process of making surimi is passed through a meat harvesting machine, the fish meat is exposed to water, placed in a rotating sieve with a 7-mesh mesh, drained, and dehydrated to produce surimi. It is said that the amount of fish meat that flows out of the rotating sieve with a 7-mesh mesh together with water is about 5% of the amount of fish meat compared to Surimi. Now, in order to collect this 5% particulate fish meat, when it is shaken while flowing into the high slope part of the cradle type separator of the present invention, the particulate fish meat and water pass between the guide plates step by step with each shaking. move in the direction. In addition, if a net with a mesh size of 7 mils is set up, water will fall into the water tank 10 along with the fish meat particles smaller than 7 mils than the mesh of the net, and 96% of the fish meat particles larger than 1 mil will fall into the water tank 10.
The water becomes as much water as possible and falls through the 7-mesh mesh into the collection tank. This is mixed with regular fish meat and placed in a dehydrator to dehydrate it to produce Surimi.

As described above, the cradle separator of the present invention is the least expensive equipment for collecting fine particles, can be easily replaced with a net suitable for the material, and clogging of the mesh can be solved by washing with washing water.

In the above, the end of the almost semicircular trough-shaped tip on the entrance side is covered by a roughly semicircular side plate, so even if materials are thrown in, they will not spill out.

The cradle separator of the present invention is designed to shake smoothly.
In order to keep the weight from above and below the center axis from being too different, a weight of 15 lbs. It is supported by bearings 15 and 16 on both sides of the central axis to make it easier to swing.

Depending on the purpose, there are large and small semicircles, long and short trough-shaped ones, large and small swing angles, and long and short round trip times.
Can be freely selected.

Effects of the Invention As described above, according to the present invention, fine particles can be easily recovered due to the simple structure, and in particular, the recovery of fine particles of fish meat contained in water bleaching and dewatering wastewater during the Surimi production process is small. This can have a significant effect on resource recovery.

It goes without saying that the present invention is applicable not only to the process of producing surimi, but also to the separation of small particles of any material.
