PURPOSE: A napa cabbage salting tank is provided to salt napa cabbages with proper and uniform salinity in a tank capable of maintaining inside temperature, thereby reducing the time required in salting in the winter season. CONSTITUTION: A napa cabbage salting tank(20) is divided into a upper space where napa cabbages are loaded and salty water is filled and a lower water jacket(24) where heated water circulates and includes a compressed air injection pipe(25) installed in the upper space. The heated water supply tank supplies heated water to the water jacket of the salting tank. A compressor supplies compressed air to the compressed air injection pipe. A controller controls the heated water supplied from the heated water supply tank to the water jacket and the amount of compressed air supplied from the compressed air injection pipe. The compressed air injection pipe is connected to an air header(10) through a pipe. An inlet(26) and an outlet(27) installed in the water jacket are connected to the heated water supply tank through a pipe for heated water to be recollected into the heated water supply tank after circulating inside of the water jacket. A solenoid valve is installed at the heated water supply pipe, of which the opening and closing is controlled by the controller. The air compressor and the compressed air injection pipe are connected with each other through a pipe, and a solenoid valve controlled to be open or closed by the controller is installed at the pipe. |
