Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mozuku for salting to prevent rot during transportation from a production area to a processing area, and in which the volume of the shrunk “raw material mozuku” is reduced to a state at the time of collection, or to a bulky state. Regarding the processing method.
[0002]
[Prior art]
In the process of commercializing “raw material mozuku” that has been directly sent in a salted and frozen state from the production area, it is thawed and then washed in a washing tank filled with water in the washing process. The sterilization is performed by adding a disinfectant, and the mechanical action of the water flow by stirring the washing water removes the salt and removes foreign substances (sea garbage, small animals, etc.) attached to the surface.
[0003]
[Problems to be solved by the invention]
By the way, as described above, the “raw material mozuku” collected at the production area is salted (and frozen) to prevent decay on the way to the processing place. The osmotic pressure oozes to the outside and lowers the bulk, so that the commercial value is halved as it is.
[0004]
However, at the processing site, in the above-described cleaning step, the water is immersed in the cleaning water and is sometimes rubbed by the mechanical action of the water flow due to stirring.
[0005]
However, with the conventional degree of normal cleaning, it is far from the state (volume) immediately after collection and bulky. To make up for this, at the current site of the cleaning process, the number of cleaning tanks must be increased, By increasing the time, the time for immersion in water is increased.
[0006]
However, this is very inefficient in terms of time, water usage, and equipment costs.
[0007]
Therefore, in the present invention, as described above, it is an object to increase the bulk of the raw material in parallel with the cleaning step, so that it can be efficiently performed.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention is designed to cause fine bubbles to act during the cleaning in the cleaning tank.
[0009]
The principle of this is described with reference to FIG. 2. As schematically shown in FIG. 2A, the cross section of “raw material mozuku M” just collected from the sea has a fiber f and a fiber f. Free water w exists between them.
[0010]
This is generally salted in salt water having a concentration of 18% to 25% in order to prevent decay on the way from the place of production to the place of processing, but after salting, Mozuku M is free water inside. w flows out to the outside by the osmotic pressure of the surrounding salt water, and as shown in FIG. The dashed-dotted circle is the outer diameter of Mozuku M in the state shown in FIG.
[0011]
When mozuku M in the state of (b) is washed in the above-described conventional washing step, water (free water w) is absorbed as shown in (c) and surrounded by a dashed line. The bulk increases to near Mozuku M in the original state. The results up to this point are the results of conventional cleaning.
[0012]
Next, in the present invention, as described above, as shown in (d), since the action of micro-bubbles B ₂ to Mozuku M of middle wash, the pressure at which the fine bubbles B ₂ is play hydraulically, mozuku Since the fibers f in M are loosened and the free water w easily enters between the fibers f, the "raw material M" expands and returns to the original state due to the free water w infiltrated between the fibers f, or , And even more.
[0013]
According to this method, or increase the cleaning tank, there is no need to lengthen the period of immersion, in order to generate microbubbles B _2, in the middle of the supply pipe of the washing water provided the pressure regulating valve, As a result, the washing can be performed by injecting the pressurized washing water into the washing tank, so that there is no need to newly provide expensive equipment, and the volume of Mozuku can be efficiently increased (returned to the original).

The above is the overall configuration of this device. Next, the operation procedure and operation of mozuku cleaning by this apparatus will be described.
[0027]
First, the three washing tanks 10, 20, and 30 are all filled with water, and the “raw material Mozuku M” thawed from the salted / frozen state is put into the first washing tank 10. In the first washing tank 10, the stirrer 1 in the washing tank 10 is operated, and by the action of the resulting water flow, foreign substances on the surface of Mozuku M are roughly removed and salt is removed. Then, based on the past data, when a predetermined time that would have been desalted has elapsed, sodium hypochlorite, which is a bactericide, is charged, and the residual chlorine concentration in the cleaning tank 10 is reduced. Sterilize for 5 to 15 minutes by adjusting to 50 ppm to 200 ppm. Up to here is the same primary cleaning as the conventional one.
[0028]
When the primary cleaning has been completed, the solenoid valve V ₁₀ for draining the signal of the timer is activated, the water tank 10 is drained through the discharge pipe P _10. When draining is finished completely, the solenoid valve V ₁₂ for the transfer is activated by the transfer pump 3, mozuku M is fed into the storage tank 4 through a transfer pipe P _12.
[0029]
When the amount of mozuku sent into the storage tank 4 reaches a predetermined amount, the sensing sensor 4s operates to stop the transfer pump 3. Simultaneously with the stop of the transfer pump 3, the cleaning operation in the second and third cleaning tanks 20, 30 is started. The lowermost work conveyors 41, 42, and 43 also start operating.
[0030]
At the same time, the bottom plate 4b of the storage tank 4 is opened by the discharge cylinder 4c, and the mozuku in the storage tank 4 falls naturally into the second cleaning tank 20 and is thrown.
[0031]
In the second cleaning tank 20, the stirrer 11 operates to stir the water in the cleaning tank 20, thereby washing mozuku with the water flow, and operating the blower 17, thereby causing air bubbles generated in the cleaning tank 20. B ₁ is the removal of foreign matter on the surface is performed by swinging the mozuku. In order to avoid complication in the figure, mozuku is not drawn to be swung by the bubble B _1.
[0032]
The washing tank 20 is always in an overflow state because the air-fuel mixture pump 14 sucks and sends the water in the circulation tank 13 below the figure in addition to the washing water that is initially filled with water. The washing water overflowing the washing tank 20 flows into the circulation tank 13, and at the same time, the overflowing Mozuku M is rubbed off on a mesh plate 13a installed at the upper part in the tank. When the detecting sensor 13s disposed on the net plate 13a senses the Mozuku M, branch pipe sends a signal to the solenoid valve V ₂₁ in the middle of the P ₂₁ open it, by operating the transfer pump 3 at the same time guide the Mozuku M to the branch pipe P _21, further through the transfer pipe P _12, transported back to the storage tank 4.
[0033]
In the above process, ozone is supplied from the ozone generator 16 connected to the middle of the circulating pipe P ₁₃ in the washing water in the pipe P _13, the supplied ozone is mixed with the admission pump 14, pressurized Due to the action of the tank 15, it is supplied to the second cleaning tank 20 in a state where the density is further increased.
[0034]
In the cleaning in the second cleaning tank 20, foreign substances on the surface of mozuki that could not be removed by the primary cleaning are removed, and the chlorine odor of sodium hypochlorite administered at the time of the primary cleaning is deodorized by ozone.
[0035]
In addition, ozone also removes the "slime" of Mozuku M by its decomposition action, and by removing the slime, the entanglement between Mozuku M is broken and the removal of foreign substances is promoted, and the taste is also improved. I do. In addition, ozone also has a sterilizing effect of 5 to 6 times that of chlorine, thereby further enhancing the sterilizing effect. When the processing in the second cleaning tank 20 is completed after a predetermined time has elapsed, Mozuku M is supplied to the next third cleaning tank 30 by the transfer conveyor 12.
[0036]
In the third washing tank 30, the circulating water is not ozone water but ordinary water, and the fine bubbles B ₂ are caused to act on the inside of the washing tank 30. In order to avoid the complexity of FIG. Again, mozuku is not drawn to the fine bubble B ₂ is acted. The fine bubbles B ₂ are generated by adjusting a pressurizing valve V ₂₂ provided in front of the cleaning tank 30 of the circulation pipe P _{22. By} causing the fine bubbles B ₂ to act on the surface of Mozuku, its "loosening" fine bubble B ₂ is for the fibers in the Mozuku by pressure during play hydraulically cause action, as schematically shown in FIG. 2, supra, free water w between each fiber f in Mozuku M Is easily infiltrated, and mushrooms M swell due to the infiltration of the free water w.
[0037]
The third mozuku the process is completed in the cleaning tank 30 is transfer conveyor 21, but are sent to the working conveyor 41, 42 and 43 side, mozuku M of the cleaning tank 30 overflows, the discharge pipe P _30, then branched After passing through the two pipes P ₃₁ and P ₃₂ , they are scraped off by the two straining baskets 31 and 32 hanging down from the upper edge of the circulation tank 22, respectively, and are collected manually. The reason why the two straining baskets 31 and 32 are provided is that the washing water and the mushroom always overflow the washing tank 30 and cannot be dealt with by only one straining basket.
[0038]
On the other hand, mozuku sent directly to the work conveyors 41, 42, 43 by the transfer conveyor 21, or draining and loosening on the first work conveyor 41 are performed manually. Drained been washing water through the drain pipe P _41, returns again to the circulation passage is recovered in the third cleaning tank 30 circulates tank 22.
[0039]
In the second and third work conveyors 42 and 43, final removal of foreign matter is manually performed. Here, the color of the belts of the two conveyors 42 and 43 is changed to check foreign matter such as dust and small animals. Easy going.
[0040]
As described above, in the mozuku cleaning apparatus of this embodiment, the free water w is impregnated between the fibers f by the “relaxation action” by the action of the microbubbles B ₂ at the same time as the normal cleaning, whereby the mozuku M Can be efficiently increased.
[0041]
According to the invention of claim 1, foreign substances on the surface of mozuku can be removed by the mozuku cleaning step, and thereafter, in the step of applying the fine bubbles, the particles attached to the mozuku are applied by applying the fine bubbles. The fibers in the mozuku can be loosened by the impact generated when the microbubbles pop due to water pressure. Then, even if the free water remaining around the fiber becomes easy to penetrate between the fibers, the muzzle expands, and the mozuku, which had been reduced in volume due to salting, should be in the state at the time of collection, or more bulky And maintain the commercial value.
According to the second aspect of the present invention, it is possible to perform the washing with the water stream of mozuku and the “relaxation” with the fine bubbles in separate water tanks.
According to the third aspect of the present invention, in the second step, the chlorine odor of the disinfectant administered in the first step can be deodorized with ozone while removing foreign substances on the surface of mozuki that could not be removed in the first step. Ozone also removes "slime" of mozuku by its decomposition action. By removing the slime, the entanglement between the mozukus is broken, so that the removal of foreign substances can be promoted and the taste can be improved. Further, ozone has a sterilizing effect of 5 to 6 times that of chlorine, so that the sterilizing effect can be further enhanced.
According to the fourth aspect of the present invention, when the stirrer is operated, the water in the tank is stirred, and the water flow can wash the mozuku. Then, the foreign matter on the surface can be removed also by swinging the muzzle generated by the bubbles supplied from the blower.
[0042]
The generation of microbubbles can be achieved simply by providing a pressure adjusting valve in the middle of the cleaning water supply pipe, and by injecting the pressurized cleaning water into the cleaning tank, it is necessary to add costly equipment. Absent. Since only microbubbles are generated during the cleaning and are caused to act on them, there is no need to increase the amount of water or to lengthen the cleaning time.
