PRAWNTO™ SHRIMP MACHINE
We manufacture the "PRAWNTO™shrimp cutter and deveiner - the most dependable
piece of equipment of its kind on the market today. Because it is powered by a ¼ h.p.
motor and constructed of aluminum and stainless steel, and high quality standards are
used in the manufacturing processes, we offer a 1-year warranty.
What exactly does the PRAWNTO™do?
It cuts the shrimp down the back to any depth while destroying most of the sand vein.
The shell is then easily removed by "pinching" or pulling it off from the underside. The
tail can be removed or left on for any presentation required.
What about cutting different sizes of shrimp?
Here is the beauty of the Prawnto... It's self-adjusting for different sizes. With our NEW
patented roller system only the depth knob is necessary for different depths of cut.
Can the PRAWNTO™butterfly?
Yes. The cut will be deep in the front to fan the shrimp for better presentation while
stopping at the tail section for efficient breading or skewering. Round cut and western
cuts are also possible with the Prawnto™.
