Description

The present invention relates to a continuous supply type automatic fish egg processing apparatus for automatically and continuously performing various processes on fish eggs from taking out processed fish eggs.
As “fish eggs”, for example, salmon roe, masuko, caviar and the like can be assumed.
As the “various processing”, for example, seasoning processing for adding a salty taste to fish eggs can be assumed.

  Conventionally, various processing methods for seasoning fish eggs are known (for example, Patent Document 1: Title of Invention “Method for Producing Seasoned Fish Egg”). As an example, in the process of adding a salty taste to a fish egg (eg, salmon roe), the fish egg (salmon roe) that has been separated from the muscles and that has been subjected to a cleaning process and a dust removal process is put into a stirrer filled with salt water. After being salted by stirring for a predetermined time, it is taken out of the stirrer and drained.

Japanese Patent Laid-Open No. 5-91858

  By the way, in the conventional seasoning process, all of the egg processing operations from the feeding of the fish egg (Ikura) to the agitator to the removal of the seasoned fish egg (Ikura) from the agitator are performed manually. For this reason, there is a limit to improving the production efficiency of seasoned fish eggs, and additional labor costs are required according to the number of skilled workers, resulting in a significant increase in the cost required for fish egg processing.

  In addition, fish egg (Ikura) is a relatively delicate material, so the processing of fish eggs from the input of the egg (Ikura) to the stirrer and the removal of the seasoned fish egg (Ikura) from the stirrer When an external action such as impact or pressure is applied inside, the outer shell of the fish egg (Ikura) may be peeled off or the fish egg (Ikura) itself may be damaged depending on the degree of the external action. There is a risk of doing. If it becomes so, the yield of seasoned fish eggs (Ikura) as a finished product without damage etc. will fall.

  Furthermore, the seasoning of fish eggs (salmon roe) that has been seasoned in the stirrer changes every moment (for example, the salty taste becomes stronger), so that the seasoning state of all fish eggs (salmon roe) becomes uneven. In order to make it uniform, it is necessary to take out the seasoned fish egg (salmon roe) from the stirrer as quickly as possible.

  However, since such extraction work requires skill, if it is not possible to arrange skilled workers, it takes time for the extraction work, and therefore it is difficult to make the seasoning of all fish eggs (Ikura) uniform. As a result, it becomes impossible to provide seasoned fish eggs (salmon roe) with a certain quality.

  The present invention has been made in order to solve such problems, and its purpose is to automatically and continuously perform processing from various processing to fish eggs to removal of processed (seasoned) fish eggs. , Making all fish eggs processed (seasoned) evenly and uniformly, and improving the yield of processed (seasoned) fish eggs as finished products, and at the same time manufacturing processed (seasoned) fish eggs of a certain quality An object of the present invention is to provide a continuous supply type automatic egg processing apparatus that improves efficiency.

To achieve the above object, the present invention is, which has a inlet and an outlet of the roe and brine, successively across from the inlet to the outlet, rotatable in hollow cylindrical a mixer body, extending along the agitator body, a screw blade which transport region continuous helically configured toward the outlet side from the inlet side at a predetermined pitch, provided in the transfer region And a plurality of stirring blades configured to traverse the conveying area in the axial direction of the stirrer body, the stirrer body facing the discharge port from the input port at a predetermined angle The screw blades are arranged so as to form a spiral with a predetermined width from the inner peripheral surface of the stirrer body toward the axial center of the stirrer body. By the central region A central opening region continuous from the inlet side to the discharge port side is formed, and the stirring blade is provided integrally and intermittently protruding from the inner peripheral surface of the stirrer body in the transport region, and the stirring The blade has a shape protruding in the inner diameter direction that is smaller than the protruding width of the screw blade in the axial center direction, and fish eggs can pass between the blade and the screw blade positioned in the front and rear in the cylindrical axis direction. It is formed with a certain predetermined gap.

  According to the present invention, the processing (seasoning) of all fish eggs is uniformly performed by performing automatically and continuously the processing from various processing to fish eggs to the removal of processed (seasoned) fish eggs. In addition to improving the yield of processed (seasoned) processed eggs as a finished product, at the same time, realizing a continuous supply type automatic egg processing apparatus that improves the manufacturing efficiency of processed (seasoned) processed eggs be able to.

The fragmentary sectional view which shows roughly the structure of the continuous supply type automatic fish egg processing apparatus which concerns on one Embodiment of this invention. It is a figure which shows roughly the specification of the continuous supply type automatic fish egg processing apparatus which concerns on one Embodiment of this invention, Comprising: (a) is the top view, (b) is the fragmentary sectional view. It is a figure which shows schematically the other specification of the continuous supply type automatic fish egg processing apparatus which concerns on one Embodiment of this invention, Comprising: (a) is the top view, (b) is the fragmentary sectional view.

Hereinafter, a continuous supply type automatic fish egg processing apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 1, the continuous supply type automatic fish egg processing apparatus of this embodiment has a fish egg inlet 2a and an outlet 2b, and is continuous and rotated from the inlet 2a to the outlet 2b. A stirrer body 2 configured to be rotatable about a central axis Ax, a screw blade 4 extending along the stirrer body 2 and spirally swung at a predetermined pitch P, and a screw blade 4 A plurality of stirring blades 6 provided at predetermined intervals along a region that spirally continues between the pitches P, and configured to cross the region, and the rotation of the stirrer body 2 Accordingly, the screw blade 4 and the stirring blade 6 are configured to rotate simultaneously.

  It should be noted that fish eggs are fed into the charging port 2a of the stirrer main body 2 together with the processing liquid via a predetermined charging path T1. The “processing liquid” is not particularly limited here because the component concentration, type, etc. of the liquid are set according to the purpose and environment of use of the continuous supply type automatic egg processing apparatus. As an example, assume that the purpose is to add saltiness to fish eggs (eg, salmon roe), and in order to achieve this purpose, salt water adjusted to the optimum salt concentration is set as the “processing liquid”. . In addition, as the input path T1, a guide member such as a spider or a pipe that guides the fish egg to the input port 2a together with the processing liquid may be applied.

  In this case, as an example, the drawing shows that the processing liquid (salt water) and the fish egg (salmon roe) are mixed with each other in a mixed state on the lower side between the pitches P of the screw blades 4. The state of being conveyed from the inlet 2a to the outlet 2b is schematically shown by a one-dot chain line.

  The stirrer main body 2 is supported by the support frame 8 so as to be rotatable around the rotation center axis Ax, and in the supported state, the stirrer body 2 has an upward slope of a predetermined angle θ from the input port 2a toward the discharge port 2b. It is arranged so as to be inclined. The angle θ of the stirrer body 2 can be defined as the angle formed by the horizontal plane H and the rotation center axis Ax, but is set according to the purpose and environment of use of the continuous supply type automatic fish egg processing apparatus. Therefore, the numerical values are not particularly limited here.

  The stirrer main body 2 has a hollow cylindrical shape that extends from the inlet 2a to the outlet 2b, and the screw blades 4 extend along the inner peripheral surface 2s of the hollow cylindrical stirrer main body 2. , And is spirally turned at a predetermined pitch P. Here, as the turning direction of the screw blade 4, either a right turn or a left turn can be applied. In the drawing, as an example, the spiral is seen from the input path T1 side (that is, the T1 direction). A screw blade 4 is shown that is turned to the left and fixed to the inner peripheral surface 2s of the stirrer body 2 (for example, welding, adhesion, etc.).

  In this case, in the stirrer body 2 having the screw blades 4 turned leftward, the rotation direction R of the stirrer body 2 is clockwise (clockwise) when viewed from the charging path T1 side (ie, the T1 direction). By setting and rotating, the fish eggs (salmon roe) introduced from the inlet 2a can be sequentially (continuously) conveyed together with the processing liquid (salt water) toward the outlet 2b.

  On the other hand, the pitch P of the screw blades 4 (also referred to as the turning pitch) is shortened or lengthened, so that the fish egg (shrimp) is processed from the input port 2a toward the discharge port 2b. The conveying speed and time can be adjusted together with the salt water), and the conveying speed and conveying time are set by adjusting the rotational speed of the agitator body 2, for example, and the continuous supply type automatic egg The pitch P of the screw blade 4 is not particularly limited here because it is set according to the purpose of use of the processing apparatus and the usage environment.

  For example, assuming a specification that completes a seasoned fish egg (salmon roe) using only one agitator body 2 (see FIG. 1), the fish egg (salmon roe) is transferred from the input port 2a to the discharge port 2b. The pitch P of the screw blades 4 and the rotation speed of the stirrer main body 2 may be set so that the optimum seasoning (salty taste) is achieved.

  The stirring blade 6 is configured to protrude from the inner peripheral surface 2 s in a state of being fixed (for example, welding, adhesion, etc.) to the inner peripheral surface 2 s of the stirrer body 2. Here, the protrusion amount (protrusion height) of the stirring blade 6 may be set to such an extent that the egg (salmon) can be stirred together with the processing liquid (salt water) by the stirring blade 6. )) Is set according to the purpose and environment of use of the continuous supply type automatic egg processing apparatus, and is not particularly limited in numerical value.

  In addition, a plurality of stirring blades 6 are provided along a region (hereinafter referred to as a spiral region) that is spirally continuous between the pitches P of the screw blades 4. The interval can be set to an equal interval or an arbitrary interval. In any case, the interval is set according to the purpose and environment of use of the continuous supply type automatic egg processing apparatus. Not limited.

  Furthermore, the stirring blade 6 is configured in a predetermined shape so as to cross (cross, cross) the above-described spiral region. In this case, the shape of the stirring blade 6 can be set to various shapes such as a rectangular shape, a triangular shape, an arc shape, and an elliptical shape, and is not particularly limited. A state where the stirring blade 6 (also called trapezoidal shape) crosses the above-described spiral region is shown.

  Here, the stirring blade 6 is preferably configured with a predetermined gap interposed between the stirring blade 6 and the screw blade 4 in a state of crossing the spiral region. In the drawing, as an example, a gap is interposed between the stirring blade 6 and the screw blade 4 on both sides in the axial direction of the rectangular stirring blade 6 (direction along the rotation center axis Ax of the stirrer body 2). The configuration is shown.

Thus, by interposing a gap between the stirring blade 6 and the screw blade 4, the stirring efficiency when stirring the fish egg (Ikura) together with the processing liquid (salt water) by the stirring blade 6 can be improved. it can.
Specifically, when the agitator body 2 is rotated, the screw blade 4 and the stirring blade 6 are simultaneously swirled to agitate the fish egg (icula) together with the processing liquid (salt water). No. 6 repeats the entry and exit of the processing liquid (salt water) mixed with fish eggs (Ikura).

  In this case, in the configuration in which no gap is interposed between the stirring blade 6 and the screw blade 4, the processing liquid (salt water) existing in the region surrounded by the stirring blade 6 and the screw blades 4 on both sides thereof is Almost all of them are forcibly conveyed as the screw blades 4 turn. In this case, there is no room for the stirring blade 6 to enter and leave the processing liquid (salt water). As a result, it is not possible to sufficiently stir the processing liquid in which fish eggs (salves) are mixed.

  On the other hand, in the configuration in which a gap is interposed between the stirring blade 6 and the screw blade 4, there is room for the stirring blade 6 to enter and exit from the processing liquid (salt water), and the stirring blade 6 ) Is mixed with the processing liquid (salt water), the processing liquid (salt water) behaves so as to rub through between the stirring blade 6 and the screw blade 4. The fish egg (salmon roe) can be sufficiently stirred together with the processing liquid (salt water).

  As mentioned above, according to the continuous supply type automatic fish egg processing apparatus which has such a structure, the fish egg (Ikura) thrown into the stirrer main body 2 with the processing liquid (salt water) from the inlet 2a is the said stirrer main body 2's. While rotating in the direction of arrow R (clockwise as viewed from the charging path T1 side (T1 direction)), the stirring blade is being conveyed toward the discharge port 2b along the rotating screw blade 4 After being subjected to a predetermined seasoning process by being stirred together with the processing liquid (brine) by 6, it is discharged from the discharge port 2 b.

  Here, assuming a specification that completes a seasoned fish egg (salmon roe) using only one agitator main body 2 (see FIG. 1), the optimum seasoning is required until it is transported from the inlet 2a to the outlet 2b. After the fish egg (salmon) with (salty taste) is discharged from the discharge port 2b together with the processing liquid (salt water), the processing liquid (salt water) and the seasoned fish egg (salmon roe) Sorted out.

  The sorting device 10 is provided along a dropping unit 10a for simultaneously free-falling processing liquid (salt water) and seasoned fish eggs (salmon roe) discharged from the outlet 2b of the agitator body 2 and the dropping unit 10a. And a sorting structure 10b. In this case, as the sorting structure 10b, resin or metal linear members are arranged in parallel in a lattice shape, and only the seasoned fish eggs (shrimp) are allowed to pass through the processing liquid (salt water). Can be made to pass.

  According to the sorting device 10, the processing liquid (salt water) and the seasoned fish egg (salmon roe) are seasoned with the processing liquid (salt water) by the sorting structure 10 b only by freely dropping along the dropping unit 10 a. Sorted into fish eggs. Then, the processing liquid (salt water) passes through the sorting structure 10b, while the seasoned fish egg (salmon roe) falls freely along the sorting structure 10b without passing through the sorting structure 10b. It moves to the next processing path L1.

  At this time, the processing liquid (salt water) that has passed through the sorting structure 10 b is returned to the stirrer main body 2 again from the charging port 2 a via the return path L <b> 2 provided in the sorting device 10. As a method for returning the processing liquid (salt water) to the stirrer main body 2 via the return path L2, for example, the processing liquid (salt water) that has passed through the sorting structure 10b is stored in a predetermined place, and this is commercially available. May be sucked by a pump (not shown) and fed to the charging port 2a of the stirrer body 2.

  As mentioned above, according to the continuous supply type automatic fish egg processing apparatus of this embodiment, the discharge | emission (removal) operation | movement of the seasoned fish egg (Ikura) from the seasoning operation | work with respect to the fish egg (Ikura) in the agitator 2 is all automated. In other words, since it can be unmanned, labor costs that were necessary in the past are not required at all, and as a result, the cost required for processing the egg can be greatly reduced compared to the conventional one.

  Moreover, according to the continuous supply type automatic fish egg processing apparatus of this embodiment, the fish egg (Ikura) thrown into the stirrer main body 2 with the processing liquid (salt water) from the inlet 2a is applied to the rotating screw blade 4. Along with being continuously and smoothly transported toward the discharge port 2b, it is stirred together with the processing liquid (salt water) by the stirring blade 6 and then sequentially discharged from the discharge port 2b.

  In this case, at present, since it is automatically and continuously supplied from fish egg (Ikura) separation to fish egg (Ikura) washing, it is only put into the agitator body 2 together with the processing liquid (salt water) from the inlet 2a. Anyone can easily produce a large amount of seasoned fish eggs (salmon roe) with a certain seasoning even when skilled workers cannot arrange.

  At this time, the turning movement of the screw blade 4 and the stirring motion by the stirring blade 6 are continuously and smoothly applied to the fish egg (salmon roe) and the processing liquid (salt water) input from the insertion port 2a ( For example, the outer skin of the fish egg (Ikura) is peeled off, or the fish egg (Ikura) itself is damaged. There is no fear of doing it. Thereby, since the yield of seasoned fish eggs (Ikura) as a finished product without damage etc. can be improved, the productivity of seasoned fish eggs (Ikura) can be dramatically increased as a result.

  In addition, the turning motion of the screw blade 4 and the stirring motion by the stirring blade 6 are continuously and smoothly applied to the fish egg (salmon) and the processing liquid (salt water) at a constant timing. Since the seasoning state of all the fish eggs (shrimp) can be made uniform without any spots, it is possible to provide a seasoned fish egg (salmon roe) with a constant quality at all times.

  Further, during the seasoning of the fish egg (salmon roe), the processing liquid (salt water) enters the salt concentration adjustment tank (not shown) via the return path L2, and again from the input port 2a at a constant concentration. Since it is returned to the stirrer main body 2, the fish egg (salmon roe) in the stirrer main body 2 is seasoned with a processing liquid (salt water) always maintained at a constant volume and a salt concentration. In this case, since it is not necessary to replenish the processing liquid (salt water), the cost required for the seasoning process can be greatly reduced.

  In the above-described embodiment, it is assumed that the seasoned fish egg (salmon roe) is completed with only one agitator body 2 (see FIG. 1). Instead, for example, FIG. 2 and FIG. As shown in the above, it is needless to say that the technical scope of the present invention also includes a specification for completing a seasoned fish egg (salmon roe) with a plurality of agitator bodies 2 that are connected in series.

2 (a) and 2 (b) show the specifications of a continuous supply type automatic fish egg processing apparatus in which the stirrer main body 2 is linearly continued in the above-described embodiment.
That is, the processing liquid (salt water) and fish egg (salmon) introduced into the first stirrer body 2 from the input port 2a through the predetermined input path T1 are discharged along the rotating screw blades 4. While being transported toward the outlet 2b, after being stirred together with the processing liquid (salt water) by the stirring blade 6 and discharged from the outlet 2b, the second unit from the inlet 2a via the second inlet path T2 After being put into the main body 2 of the stirrer and subjected to the same treatment as the first unit, it is sorted into processing liquid (salt water) and seasoned fish eggs (salmon roe) by the sorting device 10 provided at the outlet 2b Is done.

3 (a) and 3 (b) show the specifications of the continuous supply type automatic fish egg processing apparatus in which the stirrer body 2 is continuously arranged in parallel in the above-described embodiment.
That is, the processing liquid (salt water) and fish egg (salmon) introduced into the first stirrer body 2 from the input port 2a through the predetermined input path T1 are discharged along the rotating screw blades 4. While being transported toward the outlet 2b, after being stirred together with the processing liquid (salt water) by the stirring blade 6 and discharged from the outlet 2b, the second unit from the inlet 2a via the second inlet path T2 The first agitator main body 2 is put into the third agitator main body 2 from the inlet 2a through the third charging path T3 after the same processing as the first one is performed. After the same processing as above, the sorting device 10 provided at the discharge port 2b sorts into processing liquid (salt water) and seasoned fish eggs (salmon roe).

  In this case, as the input path T2 or T3, the processing liquid (salt water) and fish egg (salmon) discharged from the discharge port 2b are received, and the second or third agitator body 2 is input. What is necessary is just to apply guide members, such as a spear and a pipe, which guides to the mouth 2a while making it fall freely.
