DEVICE FOR TESTING ADHESIVE STRENGTH OF CULTIVATED LAVER USING TENSION FORCE

The present invention relates to a device to test the adhesion force of cultivated laver using tension force. Wire stretchers having an elevation rod are vertically installed in the lower part of the internal space of a device frame. Rope clampers to tightly hang a cultivating rope to which cultivated laver is attached are installed on the top of left and right sides of the device frame. A tension force measurement sensor to which a tension wire is connected is installed on the top of the elevation rod of the wire stretchers. A tong for cultivated laver is installed in the end of the tension wire. The present invention determines the adhesion force of the cultivated laver to the cultivating rope, the taking strength of the cultivated laver, by measuring the maximum tension force or a mean tension force at a time when the cultivated laver is separated from the cultivating rope while pulling downward the elevation rod with the tension wire by operating the wire stretchers in a state where the tong holds the cultivated laver on; thereby having more objective and systematic determination criterions than an existing way of determining the freshness and quality of the cultivated laver depending on the sense or experience of experts. Also, the present invention highly improves the productivity and quality of the cultivated laver through quick and active response to the change of cultivating environments as cultivated laver conditions are frequently and easily measured by taking a sample from a laver farm using a sample cultivating rope with a length of 1 m or shorter according to necessity.
