The process for sterilizing and cleaning the mozuku alga will be described below. (Sterilization Step) The sterilization tank 2 is filled with raw water in advance, and the pump 7 circulates the fluid. First, raw mozuku algae is input from the input port 17 of the sterilization tank 2. The mozuku alga is loosened and sterilized by the stirring crusher 5. At this time, the Mozuku is accumulated at the bottom of the sterilization tank 2, but is floated by bubbling from the inlet 12 connected to the compressor 9 and is stirred by the stirring crusher 5. Pebbles, shells, etc. are collected at the bottom of the sterilization tank 2 and discharged from the drain port 18. In addition,
At this time, the sluice gate 13 is closed, and while it is closed, fluid and mozuku are accumulated in the sterilization tank 2.

When the water gate 13 is opened, the fluid and mozuku in the sterilization tank 2 move to the draining tank 3. The fluid and Mozuku pass through the basket 6, the Mozuku is scraped up by the basket 6 and sent to the cleaning tank 21, and the fluid and dust of 1 mm or less are discharged from the lower part of the draining bath 3 and pass through the dust receiving basket 14. And sent to the circulation tank 4. The fluid in the circulation tank 4 is sucked by the pump 7 from the suction port 16 provided in the lower portion of the circulation tank 4.

The fluid sucked from the suction port 16 is mixed with ozone by the ozone generator 8 and the blender 10
Is sent to the inlet 11 and discharged into the sterilization tank 2. It should be noted that the temperature of the fluid in the ozone-containing water is set to 20 ° C. or lower because ozone itself decomposes when the temperature rises.

(Draining Step) The basket 6 in the draining tank 3 drains the mozuku sterilized in the sterilization tank 1. Since the entire basket 6 is punched with a diameter of 1 mm or less, the mozuku remains on the basket 6 and is thrown into the cleaning tank 21 as the basket 6 rotates. At this time, if the rotation speed is increased, the water can be further drained by the centrifugal force.

(Washing Step) Next, the step of washing the sterilized Mozuku will be described. First, the cleaning tank 22 is filled with raw water in advance, and the pumps 25 and 26 circulate the flowing water. From the sterilization tank 1, the sterilized mozuku scraped up by the basket 6 is put. At this time, the basket 31 is sprayed with ozone-containing water from the bottom surface by the shower 31, so that the charging operation is smoothly performed and the sterilization is also performed.

Ozone-containing water is discharged from the discharge port 38, and fine bubbles / nitrogen-containing water is discharged from the discharge port 39 in the traveling direction of the flowing water in the cleaning tank 2, whereby the mozuku is cleaned. It In addition, on the surface of the flowing water, the blower
The jet flow from 32 causes dust, floating substances, and the like to rise in the form of bubbles and is pushed up onto the perforated plate 33.

By making the pressure from the suction port 35 to the pump 24 negative, the ozone gas (4 g / l) generated by the ozone generator 26 can be easily sucked. The amount of ozone gas is 5 times the amount of flowing water sent by the pump 24.
-15%. Blender 2 for flowing water and ozone gas
It is pressurized by 9, and the discharge amount and pressure are adjusted to the discharge port 38. In addition, a part is sent to the shower 31. The liquid water discharged from the discharge port 38 and the liquid water discharged from the shower 31 are water containing ozone of about 1.6 ppm.

The flowing water sucked from the suction port 36 is sucked by the pump 25, mixed with the fine bubbles and nitrogen generated by the nitrogen generator 27 in the tank 30, and discharged from the discharge port 39 into the cleaning tank 22. To be done. Tank 30
The amount of nitrogen injected into the inside is adjusted to 5 to 15% of the amount discharged from the discharge port 39. The pressure in the nitrogen generator 27 is adjusted to 10% of the pressure in the pump 25 to prevent backflow.

Due to the water flow in the cleaning tank 22, the cleaned mozuku passes through the conveyor 23 together with the flowing water.
When the flowing water passes through the conveyor 23, Mozuku is blocked on the conveyor 23, and the Mozuku is scraped from the flowing water as the conveyor 23 rotates.

The cleaning tank 21 can be modified as follows. (1) Although the conveyor 23 in the cleaning step is a mesh, by adjusting the size of the mesh, the size of mozuku scraped up on the conveyor 23 and the size of dust / float collected in the overflow port 40 due to overflow You can decide

(2) The amount of dust / foreign matter that competes like bubbles on the perforated plate 33 can be determined by the amount and angle of discharge from the discharge ports 38 and 39 and the amount of air from the blower 32.

(3) Depending on the type of Mozuku, it is also possible to install stirring crushers at several places in the cleaning tank 22, stir the Mozuku and apply fine pressurized water to increase the swelling degree and cleaning degree of the Mozuku. .

The present embodiment is preferably used for food processing of Mozuku, but is not limited to Mozuku.
It is preferably used for seafood such as oysters and wakame, which are for raw food and require a high degree of swelling.

[Table 1]

[0064]

[Table 2]

[0065]

[Table 3]

From the results shown in FIG. 2, the expansion coefficient of Mozuku is almost the same as that of Example 1 although the conventional method using neither ozone-containing water nor fine bubbles according to Comparative Example 1 changes much with time. When ozone-containing water is used as the flowing water in the cleaning tank,
The expansion rate of Mozuku increases with the passage of time. In addition, when the fluid containing ozone-containing water and fine bubbles is used as the flowing water in the cleaning tank as in Example 2, the expansion rate of Mozuku increases significantly with the passage of time.

The results shown in Table 1 show that the use of ozone-containing water as the flowing water in the washing tank produces a bactericidal effect for Escherichia coli and general live bacteria with a minute residence time.

According to the results shown in Table 2, when the ozone-containing water according to Example 1 was used as the flowing water in the cleaning tank, dust in the water tank
Although the amount of foreign matter tends to decrease with the passage of time, it can be seen that when the ozone-containing water and the flowing water containing fine bubbles according to Example 2 are used, the amount of dust and foreign matter in the circulating water further decreases.

According to the results shown in Table 3, as shown in Comparative Example 2, when tap water was used as the flowing water, the bacteria grew very much with the passage of time. The use of deoxygenated water suppresses the growth of bacteria, and as shown in Example 4, the use of deoxidized fluid water and nitrogen injection further suppresses the growth of bacteria.
