Description

DETAILED DESCRIPTION OF THE INVENTION In order to uniformize the thickness of seaweed (dried seaweed) as a product to an appropriate thickness, the present invention is directed to a seaweed mixture supplied to a seaweed machine, that is, a raw material cut into predetermined dimensions. The present invention relates to an automatic seaweed blending method for blending a mixture of seaweed and water to an appropriate concentration.

The conventional method for blending raw material seaweed and water is to keep the amount of water constant and mechanically adjust the feed rate of raw material seaweed, thereby adjusting the mixture concentration to be close to the appropriate concentration.

In the case of this method of mechanically adjusting the feed rate of the raw seaweed, it is difficult to maintain a uniform concentration of the mixture due to changes in the moisture content of the seaweed over time or imbalance in the operation of the machine. Therefore, it was necessary to constantly monitor the concentration of the mixture and manually adjust the blender as the concentration changed, making it extremely difficult to uniformize the concentration with high accuracy.

The present invention aims to solve these conventional problems and eliminate variations in quality or defects in seaweed products caused by uneven concentration of seaweed mixture.

In order to achieve this objective, the automatic seaweed blending method of the present invention involves cutting raw seaweed algae and washing them with water, and then, in a seaweed blending tank in which the cut raw material seaweed and water are blended, as a first step, a seaweed blending method is carried out at a predetermined degree. While supplying raw material seaweed and water at the same time and performing preliminary mixing, a concentration sensor installed in this seaweed mixing tank detects the concentration of the mixture of seaweed and water, and the difference between the detected value and the set value is small. If it is within a certain range, continue supplying seaweed and water while adjusting the opening of the water supply adjustment valve, and if the difference between the detected value and the set value is large and exceeds a certain range, the seaweed is thin. Temporarily stop the water supply if the seaweed is too thick, and temporarily stop the supply of raw seaweed if the seaweed is too thick.Temporary mixing is carried out by continuing this until the water level in the seaweed concentration mixing tank reaches a predetermined high water level.The second step is to adjust the water level. After reaching a predetermined high water level, the supply of both raw seaweed and water is temporarily stopped, and after stirring for a certain period of time, the concentration of the mixture in the seaweed mixing tank is detected, and when the detected value is higher than the concentration setting value. supplies water into the seaweed mixing tank,
When the concentration is lower than the set value, fine mixing is performed by supplying raw seaweed, the concentration of the mixture is adjusted to the appropriate concentration, and when the concentration reaches the appropriate concentration, the mixture is sent to the stirring tank of the nori machine. shall be.

Hereinafter, the present invention will be specifically described with reference to an automatic seaweed blending device shown in the drawings.

In the figure, 1 is a seaweed concentration regulator, 2 is a concentration sensor installed in the seaweed mixing tank 3, 4 is a water tank for storing water, and 5 is a sensor for separating seaweed and water in the mixture of appropriate concentration that has been sent. 6 is a cutting washing machine that cuts the seaweed raw algae to a predetermined size and feeds it into the seaweed preparation tank 3 while cleaning it; A stirrer provided in the seaweed mixing tank 3; 8 a water supply adjustment valve that adjusts the amount of water supplied from the water tank 4 into the seaweed mixing tank 3;
P ₁ is the water supply pump, M ₁ is its drive motor, P ₂ is the transfer pump, M ₂ is its drive motor, M ₃ is the drive motor of the agitator 7, M ₄ is the drive motor of the water supply adjustment valve 8. , _M5 is the drive motor of the cutting and cleaning machine 6,
LS1 is a level switch of the seaweed mixer 3, and LS2 is a level switch of the seaweed machine stirring tank 5.

In this device, as a first step, when the water level in the seaweed mixing tank 3 reaches the low water level _h1 , this is detected by the level switch LS1, its output is input to the seaweed concentration regulator 1, and the water supply pump P The driving motor M ₁ of _{No. 1} and the driving motor M ₅ of the cutting/washing machine 6 are driven to temporarily mix the raw seaweed and water. In this state, the concentration is constantly detected by the concentration sensor 2,
When the sensor output, that is, the detected concentration value, deviates from the set value corresponding to the appropriate concentration, if the difference between the detected value and the set value is small and within a certain range, feed the raw material while adjusting the opening of the water supply adjustment valve. Continue supplying seaweed and water, and if the difference between the detected value and the set value is large and exceeds a certain range, if the seaweed is thin, stop the water supply pump _P1 , temporarily stop the water supply, and In the case of seaweed, the driving of the cutting and cleaning machine 6 is stopped and the supply of the raw material seaweed is temporarily stopped, and provisional mixing is performed until the water level in the seaweed mixing tank 3 reaches the high water level _h2 .

As a second step, when the water level reaches h ₂ , both the water supply pump P ₁ and the cutting washer 6 are stopped, and the agitator 7 (always on) in the tank 3 is sufficiently stirred for a certain period of time. I do. After that, the density of the seaweed is detected by the concentration sensor 2, and the cutting and washer 6 is driven when the seaweed is thin, and the water supply pump _P1 is driven when the seaweed is thick, so that the seaweed concentration reaches the set value. Make the mixture,
Make fine adjustments until the density reaches the set value. As the third step, when the concentration reaches the set value, raw seaweed,
The supply of both water and water is stopped, and the mixture is transferred to the nori machine stirring tank 5 using the transfer pump _P2 . The timing of the transfer is determined by the level switch LS2 attached to the seaweed machine stirring tank 5, so that when the water level falls below the low water level _h3 , the transfer pump _P2 becomes operational, and when the water level is high When the water level reaches _h4 or higher, the transfer pump _P2 is controlled to stop operating. All these control signals are generated by the seaweed concentration regulator 1.

As described above, in the present invention, the concentration of the mixture of raw seaweed and water is detected in the seaweed mixing tank,
If the difference in density is large, the difference is quickly eliminated, and if the difference in density is small, it is finely adjusted. Therefore, efficient concentration adjustment can be performed. Moreover, the supply speed is not impaired. In addition, the concentration of the mixture sent to the seaweed machine is constant,
It is possible to eliminate variations in the quality of seaweed products and the frequent occurrence of defective products.
