Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a storage device for raw seaweed algae, which is intended to store raw seaweed for a necessary time without degrading the quality of the raw seaweed.

(Conventional technology) Conventionally, in order to turn collected raw seaweed into dried seaweed, it was necessary to go through the following steps: quantitative feeding of raw seaweed, cutting, washing, dehydration, blending, and shaving. Due to the capacity of the production line, it is not uncommon to process raw seaweed (for example, 30,000 pieces) for several to several hours after landing.
In such cases, it is known that among the raw algae delivered to the processing line, there is a difference in quality between the first processed seaweed and the last processed seaweed.

Normally, collected raw algae are sent to a certain amount (for example, 1000
Stack them in a basket and sprinkle water from the top to store them. In addition, an automatic seaweed supply method has been proposed in which a mixture of raw algae and salt water is stored in a cooling water tank and the required amount is pumped out (Japanese Patent Publication No. 57-39633). Furthermore, a ripening machine has been proposed in which raw algae are cut and washed, stored in a storage tank, and repeatedly sprinkled with water and stirred to reach a predetermined degree of ripeness (Jikko Sho 59).
−34309).

(Problems to be solved by invention) In the above, when the baskets are piled up and water is sprinkled, the watering effect only extends to about 2 baskets from the top, so the lower ones (5 to 6 baskets stacked) are deteriorated. I was afraid.

Next, the method of storing salt water in a salt water tank requires a large amount of salt water (preferably sea water), so it is difficult to use it unless it is located close to the coast. Also, if the amount of salt water was small, there was a risk of deterioration during storage. For example, 30,000 pieces of seaweed required more than 3 tons of seawater.

Next, the ripening machine improves the quality when the raw algae are relatively coarse (when the waves are rough or near the end of harvesting), but when the raw algae are soft at the early stage of collection, the quality deteriorates rapidly. There were some problems, such as the possibility that

(Means for solving the problem) This idea uses a relatively small amount of salt water and prevents changes in the quality of the raw algae by agitating the raw algae in salt water and spraying and circulating cold salt water. It was extremely successful.

In other words, this invention includes a raw algae lifting device consisting of a rotating screw for raising raw algae in the center of a bottomed mesh tube with a non-porous part of a predetermined height at the bottom, and a guide tube provided on the outside of the lower part. A rotating stirring rod was installed vertically between the mesh tube and the rotating screw, and a cold salt water spray nozzle was provided on the upper peripheral wall of the bottomed mesh tube, which was connected to a water supply device and a water cooler. This is a storage device for raw seaweed algae.

By constantly maintaining the sprayed cold brine at around 5°C as described above, the raw algae can be preserved at around 5°C.

In short, since raw algae are alive, it is desirable to store them under conditions as close as possible to those found at sea.If they can be stored under these conditions, deterioration can be prevented even for a considerable period of time. However, by vertical convection, the temperature inside the tank becomes uniform, and even if the amount of salt water is small and the raw seaweed at the top pressurizes the raw seaweed at the bottom, the top and bottom will be replaced before any negative effects occur. , homogeneous storage becomes possible.

(Function) In this invention, a device is installed in the center of the net tube with a bottom to make the raw algae move up and down, and a cold salt water spray nozzle is installed in the upper part of the net tube. Convection flows upward from the bottom and then downward from the top of the periphery, and cold brine is evenly distributed to keep the temperature relatively low. However, the entire area is maintained under uniform conditions due to convection.

(Example) Next, an example of this invention will be described based on FIGS. 1 to 4.

A non-perforated portion 2 is provided at a predetermined height on the lower side wall of a net tube 1 made of punched metal and has a planar regular octagonal shape, and a bottomed net tube is formed by a bottom plate 3, and A rotating screw 4 is installed vertically,
A guide cylinder 5 is loosely fitted to the lower part of the rotating screw 4 over a predetermined height to constitute an algae raising device. The cylinder 5 constitutes a screw conveyor 7. A support rod 8 is installed horizontally at the mouth of the mesh tube, and a shaft 9 of the rotary screw 4 is rotatably installed on the support rod 8. A boss 10 is loosely fitted to the shaft 9, and a gear 11 is attached to the boss 10. In addition to fixing the
The bases of the stirring rods 12, 12 are connected. The stirring rods 12, 12 have a horizontal part and a vertical part, and the vertical part is inserted vertically between the screw conveyor 7 and the mesh tube 1.

A sprocket 13 is fixed to the shaft 9, and a motor 1 with a transmission is installed vertically on the upper side wall of the mesh tube 1.
Sprockets 15 and 16 are fixed to the shafts 4 and a chain 17 is attached to the sprockets 13 and 16. Further, an intermediate shaft 18 is installed vertically on the support rod 8, a sprocket 19 is fixed to the upper part of the intermediate shaft 18, a gear 20 is fixed to the lower part, a chain 21 is attached to the sprockets 15 and 19, and the gear 20 is connected to the gear 11. interlock.

A water pipe 22 is installed inside the mouth of the mesh tube 1, and nozzles 23 are provided at equal intervals inside the water pipe 22.

The storage device of the above embodiment is used, for example, by installing A and B in parallel as shown in the fourth figure. That is, they are installed in parallel at predetermined intervals in the drain tank 24, the lower discharge ports of each mesh tube are connected to both ends of the collecting pipe 25, and one end of the transfer pipe 28 is connected to the middle part of the collecting pipe 25 via a valve 26. , the other end of the transfer pipe 28 is connected to the suction side of the pump 27, and the discharge pipe 29 of the pump 27 is connected to the dehydrator 30.
The chute 31 of the dehydrator 30 is placed above the hopper 33 of the cutting and washer 32. 3 in the diagram
4 is a control panel, and 35 is a dehydrator. In the figure, 52 is a vinyl sheet.

In the above, when a predetermined amount of raw algae is put into each mesh tube 1, 1 and the motor 14 is started, the sprockets 13, 15, 16, 19 and the chains 17, 2
1 rotates the screw conveyor 7 and stirring rod 12, respectively. Therefore, the raw algae in the mesh tube 1 flow as shown by arrows 36 and 37. On the other hand, when the water pump 38 is started, the salt water (previously a mixture of seawater and fresh water) in the drain tank 24 is sucked into the cooling device 39.
Then, water is sprayed all at once from the nozzles 23 and 23 via the water pipe 40. Therefore, the raw algae are uniformly sprinkled with water during convection, come into contact with salt water and air, and are preserved in conditions similar to those at sea. Then, when the pump 27 is started and the valve 26 is opened, A, B
The raw algae in one of the mesh tubes is sent to the required amount as indicated by the arrow 41, and then processed through various known processing machines. In the figure, reference numeral 42 is a raw algae detector, which can warn of overflow due to excessive raw algae, and can also notify that there are few raw algae left.

(Effects of the invention) According to this invention, the raw algae in the mesh tube are stirred by convection by a lifting device consisting of a rotating screw and a guide tube installed outside the bottom of the screw, and cold salt water is sprinkled on the raw algae, so that the raw algae can be grown in the sea. It is stored under almost the same conditions as in the case of raw algae, and there is no risk of deterioration even after a relatively long period of time, which has the effect of preventing quality changes over time in raw algae processing.
