2 DESCRIPTION
2.1 MECHANICAL
When the 700MC is turned on with the guard(s) in the closed position, the head assembly reciprocates.
The conveyor advances when the blades are fully retracted at the top of each stroke.
The meat to be tenderized is simply placed on the conveyor. The powered conveyor advances the
product under the blades. Any blade that strikes a bone will automatically stop its downward stroke while
the other blades will continue to penetrate the meat. As the blades return to the top of the stroke, the
retracted blades are pushed back into position by the soft plastic reset pads.
The blade assemblies are mounted between two “H” shaped stainless steel frames, the head frame and
the guide frame. The head frame is bolted to the top of the one and one-half inch diameter main
uprights. The guide frame is mounted below the head frame on the smaller one inch diameter guide
uprights.
The main and guide uprights extend through the top of the cabinet and are guided by oil-impregnated
bronze bearings. These bearings are held in the main frame casting that is bolted to the underside of the
top of the cabinet. The lower ends of the main uprights are bolted to the cam plate. This is driven by a
cam roller attached to the crank cam on the output shaft of the transmission. The transmission is driven
by a two horse power electric motor. The lower ends of the guide uprights extend through the toggle
clamp assemblies and guide raisers. The guide raisers with their cushions are attached to the main
uprights and the clamp pivots are attached to the guide uprights.
As the 700MC makes its downward stroke, the head and guide frames descend until the guide frame
contacts the meat. At this point, the guide frame stops while the head frame continues downward to the
bottom of the stroke. The guide frame is locked on the stationary toggle rods by the toggle assembly.
This holds the meat down on the conveyor belt as the head frame travels upward withdrawing the blades.
As the main uprights and the guide raisers reach the clamp pivots at the position where the guide frame
had been locked, the unlock cushion lifts and levels the toggle clamp. With the toggle clamp level, the
toggle rings release allowing the guide uprights and guide frame to rise to the top of the stroke.
The crank cam also actuates the cam follower assembly and rocker arm for the conveyor advancement.
The cam follower causes the rocker arm to pull down on the pull rod, operating the bell crank. The bell
crank causes the push rod to operate the index arm. As the index arm moves, the pawl on the index arm
engages a tooth on the index wheel causing the conveyor to advance one increment. As the index wheel
advances, a serpentine track on the cam drive wheel causes the conveyor to move side to side
producing the proper interdigitation of the blades to maximize tenderization. The crank cam is designed
to have the rocker arm and conveyor drive advance the conveyor just as the head assembly is near the
top of its stroke with the blades out of the product.
2.2 ELECTRICAL
MN700-MC0010
2-1
The electrical control system is located in a sealed compartment at the input end of the Tenderizer
cabinet. The control system includes a control transformer, fuses, motor starter, phase sensor, and relay.
The electrical schematic, MN045770, is located at the rear of this manual. The incoming three-phase
power is connected between terminals 1, 2 and 3 of the main terminal block. It is then fed through the
