Device and principle of operation
The body of the chopper is of welded construction. Its end walls are the supports of the grinder drum bearings. A counter knife is attached to the rear removable cover of the case. The lower sloping part of the body and the protruding part of the meat grinder pipe have double walls. When processingfrozen fodder hot water should be fed into these cavities.
The frame of the all-welded construction is made of channel roll No. 16. Shock absorbers are attached from below.
The knives in the disc are fixed with steel clamps. The drum as a whole with knives and clamps is statically balanced.
An auger with a cutting tool consists of the following parts:
screw of welded structure with variable pitch;
reception grid;
two lattices;
two knives.
The chopper drum is driven by an electric motor.
The driven clutch of the drum simultaneously serves as a pulley for driving the auger through a V-belt transmission. Belt tension is carried out by a tension roller.
The loading hopper is an all-welded construction made of rolled sheet, equipped with a barrier curtain. A collector for ego washing is installed in the upper part of the bunker.
For the operation of the G2-FIR shredder, meat and bone products are fed through a hopper to a drum, pre-grinded by it and thrown onto a screw, which is fed to the cutting apparatus, where they are finally shredded.
For the operation of the chopper, a place is selected in a feed kitchen or a special room with a horizontal concrete platform and positive temperature in winter.
By pressing the "Start" button, we spin the drum to full speed. We check the direction of rotation of the drum and the absence of noise. We run in the shredder at idle speed, and after a trial run, we start work. The required amount of product to be processed must be prepared in advance at the site where the shredder is installed.
Load the chopper evenly, avoiding idle runs.
When the chopper is working, especially on frozen products, it is necessary to heat the neck of the cutting device and the body with steam, for this purpose a heating chamber with condensate inlet and outlet fittings is provided.
