Description

[Detailed description of the invention] The present invention relates to a method for promoting ripening of seaweed.

In the conventional nori aging method, the seaweed raw material supplied to the raw material tank is aged in a rice bran style.
In terms of equipment, an inner tank through which water can freely enter and exit is fixed to an outer tank.
The inner tank is configured to support a rotary shaft with a winged seaweed raw material by a bearing, and to discharge the matured seaweed from a feeding port at the bottom of the inner tank.

Therefore, the seaweed raw material is supplied from the previous process to the inner thigh tank in a water-containing state, and water is added thereto as necessary, or the seaweed raw material that has been dehydrated in the previous process is supplied to the inner tank, and then water is added as necessary. By adding water and performing a fine coagulation process, it is possible to achieve the effect of ripening the hard seaweed material.
However, in the case of such conventional methods, the ripening process is merely carried out by a mechanical means of drying the seaweed, and therefore, it is difficult to achieve a sufficient effect of ripening the seaweed in a short period of time, and it is difficult to achieve a sufficient effect of ripening the seaweed in a short period of time. In some cases, it takes a lot of time to process the barrels, and in some cases the barrels are sent to the next post-processing step in an insufficiently aged state. In particular, when insufficiently ripened seaweed is dried, the small pieces of seaweed shrink and shrink in a warped shape, which in turn causes dry damage such as cracks and holes in the dried seaweed. On the other hand, if it is not possible to mature the seaweed over a long period of time, it will disrupt the flow of the entire seaweed production process.
It is necessary to deal with this problem by installing two or three such conventional machines in series, which requires securing more installation space than necessary and also increases equipment costs. there were. In addition to the above-mentioned points, the present invention was invented with an eye to the fact that seaweed manufacturing operations are carried out at times when outside and water temperatures are low, and this is a factor that prevents the seaweed from achieving a sufficient ripening effect. When the seaweed raw material supplied to the raw material tank is locked and matured, the seaweed raw material is subjected to heating treatment, thereby promoting smooth and rapid aging of the seaweed raw material for hard seaweed-like raw materials. This is an attempt to deal with this problem in a useful way.

As shown in FIG. 2, the seaweed ripening machine is interposed between the cutting and cleaning device 23 for the collected seaweed raw algae and the dehydration device 24 supported and fixed on the upper part of the base 24a.

First, seaweed raw material x, which has been cut and refined in the cutting and washing unit 23 and is a mixture with water y, is fed to the inner tank 4 via the feed pipe 26 by the suction and feed force of the feed pump 25. At the stage when a certain amount of such seaweed raw material x is stored in the inner tank 4, specifically, to the extent that water y from the seaweed raw material Or, if the amount of water secreted is small, the valve 22a is activated to inject water from the supply port 18. Next, the motor 17 is driven to rotate the rotary shaft 5 continuously or intermittently to feed the seaweed raw material x in the inner tank 4, and the air supply proar 11
Alternatively, the water supply pump is driven to blow out the pressurized air or water from the through hole 8a of the fly wing 8. Furthermore, the valve 13a is opened and closed to spray water continuously or intermittently from the through hole 12a of the sprinkler pipe 12. Then, seaweed raw material x
Not only is the seaweed raw material x matured by the refinement-like Takaazusa process, but also the air or water sent from the through hole 8a is used as the raw material for seaweed in the inner tank 4
It effectively spreads to every corner of the seaweed raw material x, thereby significantly promoting the ripening of the seaweed raw material x. Moreover, the through hole 12 of the water sprinkler pipe 12
By sprinkling water from a, fresh water leaks downward as the seaweed raw material , is discharged from the overflow row 4a of the water level adjustment pipe 14. Even with such water sprinkling from above, the water in the inner tank 4 is replaced and replaced, and the mulch treatment is performed, so that the ripening effect is further promoted. In the above case, since the seaweed manufacturing work is carried out at a time when the outside air temperature and water temperature are low, the pressurized air supplied by the air supply blower 11 or the pressurized water supplied by the water supply pump is heated to the required temperature using a separate heater device. The seaweed raw material However, even in this case, if the seaweed raw material is heated, it is useful to further promote the aging effect of seaweed on hard seaweed raw materials.

In addition, the water level adjustment pipe 14 is separately prepared.
4'', the water level can be easily adjusted depending on the hardness of the seaweed.The seaweed raw material The aged seaweed is sucked and fed from the feed port 18 by driving the feed pump 20 in response to a command from the feed pump 20 (not shown). The water is fed to the next process, the dewatering device 24, for dehydration treatment.During this feeding, the valve 22a is opened to inject water into the water injection ridge 19 and the feed port 18, and from the feed port 18. As a result, when the seaweed raw material x in the inner tank 4 decreases below a certain amount, it is detected and the feed pump 25 is activated to supply new seaweed raw material x. Figure 3 shows a second embodiment of the nori ripening machine, with a through hole 5a in the side wall of the pipe b of the rotating shaft 5, and a hole 5a in the outer periphery of the inner tank. A through hole 10a is formed through the provided air supply or water supply pipe IW, and a through hole 27a is formed in the fin air or fountain chamber 27 of the rice bran bottom 3, respectively.

After configuring one or two combinations of such configurations, the compressed air supplied by the air supply blower or the compressed water supplied by the water supply pump can be supplied by a separate heater device in the same way as in the first embodiment. Flooding to a required temperature and heating the seaweed raw material
Alternatively, heating the fresh water fed through the water supply pipe to a required temperature using a separate heater device is useful for further promoting the nori ripening effect. The present invention is a seaweed ripening method in which the seaweed raw material supplied to the raw material tank is aged like a washing liquid as described above, in which the seaweed raw material is heated. Regardless of the hardness of the seaweed, it achieves the effect of ripening the seaweed in a relatively short time, and not only improves processing capacity and work efficiency, but also contributes to improving the quality of seaweed products. Brings various effects.
