Production device and preparation method of kelp monosodium glutamate

The invention relates to the technical field of kelp processing, in particular to a kelp monosodium glutamate production device and a preparation method thereof.The kelp monosodium glutamate production device comprises a drying room, two guide rails and a set of rotation driving mechanisms are arranged at the bottom of an inner cavity of the drying room in parallel in the feeding direction, and a plurality of kelp hanging frames are connected between the two guide rails in a rolling mode. The driving piece drives the reciprocating screw to rotate, so that the sliding block and the rack are driven to slide back and forth along the reciprocating screw in a reciprocating mode, the rack is intermittently meshed with the ratchet wheel assembly in the reciprocating sliding process, and therefore the rotating column and the hanging rod are driven to intermittently rotate by a fixed angle. According to the kelp drying device, the hanging rods are sequentially rotated to the positions right facing the heating assembli
