RENDERING PRE BREAKER

MO D E L : PB6 PR E BR E A K E R


The PB6 Pre Breaker is a heavy duty machine designed for rapid size reduction of whole fallen animals, condemned carcasses, green bone etc. and similar materials in the rendering industry.

The cutting edges inside the machine are formed from a specific hard facing grade of steel. The machine operates on the principle of a shearing action to rapidly process high volumes of material.

PB6 PreBreakers can be supplied as bareshaft machines (as per image this page) or as a complete turnkey item, including the drive motor, gearbox, couplings and baseframe. If processing of smaller carcasss and throughputs is required, the use of a smaller PB4 or PB3 Pre Breaker should be considered.

RENDERING GUT CUTTER

MO D E L : GC3 GU T CU T T E R


The GC3 Gut Cutter is a heavy duty machine designed to rapidly reduce the size of soft offals and similar materials in the rendering industry, they are also extensively used in the commercial fishing industry.

The cutting edges inside the machine are aligned to a very close tolerance, providing a clean sharp cut rather than a shearing action used in other similar machines. The shearing action of similar machines is not suited for use on soft materials.

GC3 Gut cutters can be supplied as bareshaft machines (as per image this page) or as a complete turnkey item, including a drive motor, couplings, flywheel and baseframe. In marine conditions, we recommend a special order of a galvanized body GC3 Gut Cutter, and can supply hydraulically operated models.


Developed primarily for the meat processing industry, the GC3 Gut Cutter is ideal for handling:

Washed or unwashed soft cut offals (cattle, sheep, pig etc.)

Whole sheep or lamb paunches and runner sets

Fish Bone, whole fish, fish scraps


Rapidly reduces the size of soft materials with high precision cutting edges

BATCH RENDERING DRIER

MO D E L : NO5 ME L T E R


The No5 Melter is a heavy duty machine designed to rapidly cook all forms of rendered material. It has also successfully been used in other industries for various drying operations. The No5 Melter has both a Steam heated shaft and a Steam heated jacket, for maximum efficiency. Jackets are normally lagged with 50mm of insulation after machine installation.

The No5 Melter has the advantage over continuous cooker style units, in that as a closed vessel, pressure can be built up during the cook cycle which speeds the cooking process. Continuous cookers normally only operate at atmospheric pressure.

MEAT RAIL SWITCHES

MO D E L : MRS CA S T IR O N SW I T C H E S


Mechanically operated rail switches are frequently required in the Meat Industry for diverting skids to different rails, and are prolific in Chiller Room situations amongst others. A simple tug on the pull handle toggles the switch from one direction to the other.

Our MRS switches are produced from Cast SG Iron, chosen for its excellent strength, wear and corrosion resistance, as well as its self lubricating properties, effectively meaning they are largely maintenance free.


Main components cast in an SG grade Iron excellent wear and corrosion resistance
