Abstract
An apparatus for cutting and deveining shrimp comprises a motor driving means inside a housing and a cutting mechanism outside the housing. A pair of rotating flexible disks grasp shrimp bodies and propel them past a cutting disk which slices the sand vein from the back of the shrimp. An idler roller is mounted on an adjusting shaft which may be positioned to adjust the depth of cut on the shrimp. An improved adjusting mechanism and external crank arm on the adjusting shaft enables adjustment of the idler roller while completely sealing the motor housing from any debris from the cutting operation. Polyurethane flexible disks reduce the growth of surface bacteria.
Claims10
In an apparatus for deveining shrimp of the type having a housing, a motor within said housing, means external to said housing for gripping and propelling said shrimp, means external to said housing and adjacent said gripping and propelling means for cutting the sand vein from said shrimp, and means for adjusting the position of said cutting means in relation to said shrimp, the improvement wherein:
- said a rotating shaft and a sealed journal supporting shaft for adjusting said cutting means in relation to said shrimp includes means for preventing debris from said shrimp from entering said housing.
An apparatus for deveining shrimp comprising:
- a housing;
- a vertical housing plate having three apertures therein mounted at one end of said housing;
- a motor mounted inside said housing;
- a first drive shaft extending horizontally through the first aperture in said housing plate;
- a second drive shaft extending horizontally through the second aperture in said housing plate and mounted below said first drive shaft;
- drive means connecting said motor to said first and second drive shafts for rotating said shafts;
- means mounted on said first drive shaft for gripping and propelling shrimp bodies;
- means mounted on said second drive shaft and positioned below said gripping and propelling means for cutting the sand vein from said shrimp bodies;
- an adjusting shaft extending horizontally through a third aperture in said housing plate for adjusting the position of said shrimp bodies in relation to said cutting means, said adjusting shaft having two equal-but-opposite bends external to said housing, said bends creating a portion of said adjusting shaft which is parallel to, and offset from, the axis of rotation of said adjusting shaft;
- and
- means connected to said adjusting shaft for rotating said shaft from within said housing.
