4 Chapter Machine Description This machine or production line is manufactured from many components and the final operation of the machine is to achieve either a bar shaped extruded product or a ball. For either of these two final products to be realized correct product has to be inserted into the first part of the line. The line is made up of the following essential sub machines. 1. The extrusion system 2. The extrusion nozzle 3. The take off /away conveyor system (no longer in system) 4. The cutter/blade system 5. The take away conveyor 6. The ball forming system 7. The take away conveyor The raw material is to be entered into the extrusion line via the hopper on top of the extrusion unit, care must be taken to ensure that the product does not clog up the extrusion transfer wheels, should this happen, the raw material is either to sticky or to tough and smaller quantities should be thrown into the extrusion to allow for easier extrusion. Should the extrusion line extrusion transfer wheels get clogged up, then the unit will need to be cleaned either by dismantling the unit and cleaning or removing the material and running some hot water through the extrusion system to alleviate the blockage. It must be understood that the extrusion system has two drive systems, The product extrusion transfer wheels and the screw extruder. Both these units can be adjusted for speed individually. The appropriate speed of these two items as well as the relative speed can only be determined when the line is running with appropriate product. This will take time and experience to determine as there is no correct setting. NOTE: Air temperature, relative humidity and fluidity of the product will determine the final extrusion settings.

5 Extrusion Transfer Wheels Extrusion Screws (Two) Note: See mechanical drawing of the system for removal and cleaning/dismantling Extrusion heads will determine the final shape of the product. If the product is pushed out of the extrusion head and the product is not consistent, i.e. It contains bubbles or space between the product. Change the speed settings of the extruder to alleviate these issues. The final product shape will be determined by the extruder nozzle. Extrusion Nozzle The extruded product will exit the nozzle and take on the same form as the nozzle internal. For bars the nozzle will be 4 sided and for the ball former the nozzle will be round. The final weight of the product will be determined by a combination of features. Bulk density of product Extruded area. Extruded cut length The take off conveyor speeds can be set so as to match the extruded product speed. Too fast and the product will be pulled apart and too slow and the product will be compressed causing a snake effect on the conveyor belt. The rope effect of the extruded product can now be passed under the cutter and the product can be cut accordingly. Correct length of the cut product can be achieved by changing the cutting frequency of the blade. This cut product length will determine the final bar length. For balls the product length must be determined so as to not jam the ball former and the ball weight will be determined from this length. The ball formed rope will be approximately equal in all dimensions prior to the ball former. Should a smaller ball be required, the following parts require changing. Extrusion nozzle Ball former plates- Male and Female

6 Ball former plates Note: Cut product of the incorrect size will not go through the ball former and will cause a blockage. The final exit conveyor can be set so as to provide the operator with a reasonable packaging experience. v Correct setting up of the machine is essential for correct operation and specific attention should be paid to the following areas. The person who operates this packaging machine must know the contents of this manual in detail. The operator and at least two mechanical and electrical staff will need to be trained on the machine after commissioning to ensure that daily maintenance of the machine. NOTE: All these areas will be covered in a later chapter (Chapter 3) Machine Safety Guides The following safety guides pertaining to this machine must be observed in order to prevent accidents with this machine: The installation of all safety devices, such as protective doors, must be closed to enable the machine to operate. Note these parts cannot be dismantled. The machine operators must check the machine for any foreign objects that could cause damage to the machine prior to switching on and operation. Once the machine is running, no hands are to be placed or inserted near the sealing area as well as any of the running parts Safety with the Operational Parts The power supply must be switched off when the machine is being cleaned or repaired. If the machine is equipped with a hopper, do not insert hands or fingers into the filling device during operation.

Carefully break open the exterior panels to reveal the machine and its working parts. The machine will be covered in a plastic protective cover. This is to be removed. Make sure that no parts have been damaged during transport, or fallen off the machine. The machine will get to you with certain parts dis-assembled. These need to be fitted to the machine to resemble the photos above of the machine. The machine is affixed to the wooden pallet by four metal brackets. Remove these brackets and discard or keep for future use. The doors and covers have been taped closed for safety reasons; these taped parts can now be opened. Surface rust can take place due to the excessive sea air during shipping. This will only be surface rust and a dry cloth should be used to remove this rust residue. The entire machine was shipped with an oil coating on the machine to safeguard the machine from corrosion. This can now be removed with a very light detergent. The non stainless steel parts should be re-oiled to prevent rusting taking place after cleaning. Do not leave the machine wet. The machine is top heavy and as such care should be taken when handling the machine and removing it from its wooden pallet. Handling After unpacking, a forklift can be used to maneuver the machine into position; the length of the fork must be long enough to reach under the width of the machine. See figure below. The center of gravity of the machine is about 1500mm from the right hand side (the electrical box side) frontal view of machine. NOTE: Do not handle the machine on the upper surface of the machine.
