Description

[Detailed Description of the Invention] The present invention relates to a device for preventing cloudiness that occurs in dried seaweed during the production of seaweed, and is aimed at obtaining seaweed of a certain quality with good color and luster.

During the production of seaweed, if the dried seaweed (product) becomes cloudy and lacks luster, the value of the product will be significantly reduced.

The cause of this cloudiness is largely related to the salt concentration of the raw seaweed solution, which is a mixture of raw seaweed and water at a certain ratio.The salt concentration also affects the product's flavor, color, luster, and drying time of the seaweed. It was found that the effect of

In other words, it has been found that if the salt concentration is too high, not only will the taste deteriorate, but also the color and luster will be lost, and the drying time of the seaweed will take a long time.

Therefore, it is necessary to adjust the salt concentration of the stock solution in the mixing tank to within a certain range.

This has no meaning at all once the dried seaweed is produced, and the concentration of salt contained in raw algae varies depending on the type of raw algae, the time of collection, the place of origin, the depth of the seawater, etc., so rejecting defective products. This is because in order to reduce the salt concentration, it is better to control the salt concentration immediately before making seaweed.

The present invention was developed based on the above-mentioned viewpoint, and aims to prevent the occurrence of cloudiness without reducing the flavor of the product, to fully display the color and luster, and thereby to obtain a large quantity of products of a constant quality. This is what I am trying to do.

The gist of the present invention is that in a seaweed washing and mixing machine that stirs and mixes raw seaweed washed by a washing machine 1 and water at a constant ratio in a mixing tank 3, a detector 10 is installed in the mixing tank 3 to detect the salt concentration. It is characterized by being equipped with a controller 11 that automatically controls the washing time or amount of washing water for raw seaweed in the washing machine 1 so that the salt concentration falls within a predetermined range of concentration values in accordance with the salt concentration detection signal of the detector 10. There is a device to prevent fogging of seaweed.

The present invention will be described above with reference to the drawings. After the raw algae is cut into pieces by the cutter 2, it is sent to the washer 1 where it is agitated and washed.

The washed raw seaweed is then sent to the mixing tank 3 of the mixing machine, where the raw seaweed and water are stirred and mixed in a predetermined ratio.

Conventionally, this blended stock solution was fed to the sand straining tank 6 of the paper machine 5 using the pump 4, and then a certain amount was allowed to flow down the paper machine 5, and then sent to the bottom of the paper machine 5 by the chain conveyor 7. A method has been adopted in which raw seaweed is made into paper sheets on a seaweed cage.

In addition, numeral 9 in the figure is a sewage regulating machine that moves up and down in cooperation with the box of the paper machine 5 and performs the action of making seaweed.

In such conventional methods, the salt concentration of the stock solution is not adjusted at all, so as mentioned above, the product is defective and the defect rate is high.

Therefore, in the present invention, a detector 10 is provided to detect the salt concentration of the raw solution in the mixing tank 8, and a signal from this detector 10 is sent to a controller 11, and the number of times and speed of stirring of the washing machine 1 are adjusted according to this detection signal. , the amount of washing water, etc. are controlled individually or in combination, and the washing time and/or amount of washing water for the raw seaweed is controlled.

As the detector 10, a salt meter or the like which detects changes in the conductivity of the stock solution is generally used.

Based on the detection signal from the detector 10, the controller 11 controls the rotation of the stirring blade or porous stirring cylinder motor of the washing machine 1, or controls the opening degree of the washing water valve, etc. The apparatus is configured to control the washing time and/or amount of water for washing raw seaweed.

Therefore, according to the present invention, the salinity concentration of the raw solution in the mixing tank 3 is automatically adjusted to a certain range, and the pump 4 sends a certain amount of this to the paper machine 5 via the sand strainer tank 6 to make paper. Therefore, the dried seaweed (product) obtained through the subsequent steps of dehydration → drying → peeling the seaweed does not become cloudy and has a full luster of color and is rich in commercial value.

Furthermore, even if the properties of the raw algae change due to the type of raw algae, the salt concentration of the stock solution is adjusted just before papermaking, making it easy to control and dramatically reducing the defective rate. The product can be obtained in large quantities.

In addition, the drying time of seaweed can be kept constant, allowing efficient production.
