PURPOSE:To make possible to compulsorily realize half-drying similar to natural draft drying by providing plural suspending frames of vertical multistage type on self-standing vertical rotation shaft freely changeable of rotating speed through connecting frames and changing the rotating speed according to weather conditions. CONSTITUTION:A casing pipe 11 for a vertical rotating shaft 1 is vertically installed and fixed on a base stage 3, then the vertical rotating shaft 1 is vertically installed in freely rotatable structure through square flange-type bearing units 12 and 13 provided up and under the casing pipe. Suspending frames 2 are provided at vertical intervals of about 40cm so as to keep nearly horizontal arrangement as a whole and connected and supported to the vertical rotating shaft 1 through connection arms 21. Preferably the frames 2 are shaped like ring having about 100cm diameter. Raw cuttlefishes are compulsorily rotated with suitably controlling rotating speed according to weather condition, i.e., beach wind or degree of clear weather, in natural environment of beach the most suitable for drying of cuttlefish to drastically shorten dying time and make possible to perform uniform and nearly ideal drying. |
