The invention relates to the technical field of
mussel cleaning, in particular to efficient cleaning equipment and a cleaning method for grading and shell protection of mussels. Comprising a
machine frame, a cleaning
pool and a conveying belt are arranged on the
machine frame, the conveying belt is provided with a horizontal conveying section submerged below the liquid level of the cleaning
pool and a climbing section penetrating out of the liquid level in an upward inclined mode, a grading mechanism is arranged on the front half portion of the horizontal conveying section and comprises a vibration material frame and a net bag arranged in the vibration material frame, and a height adjusting frame is arranged on the
machine frame. A vibration generator is arranged on the height adjusting frame, the net bag is composed of a fixed net and a movable net, an inner frame is arranged in the vibration material frame and can drive the movable net to be close to or away from the fixed net, and a material falling net gap is formed between the fixed net and the movable net. By adjusting the blanking net gap between the movable net and the fixed net, stage-by-stage release of mussels is achieved,
extrusion damage is avoided, then
dirt in the mussels is removed under the cleaning action of pre-cleaning,
aeration turning and washing and variable-frequency spraying, and the cleaning effect is improved.
