A considerable proportion of the oven cost is in building the steel structures, baking chambers, heat exchangers, frames, covers and insulation. This work can be carried out successfully in many countries. There is no need to import large steel fabricated items with high capital cost, which can be manufactured successfully locally.

FIG 3: Oven assembly with completed baking chambers and burners
Most biscuit oven manufacturers now assemble their ovens into complete modules before shipment. This reduces the time required on site to assemble the oven. However, it results in most of the assembly work being carried out in a high-cost environment and in incurring high shipping costs. Shipment of a typical oven may require 10-20 containers with both cost and time disadvantages to the project. The capability to manufacture ovens locally in the growing markets is an important advantage.
FIG 4: The tasks and team
Mechanical engineering design
Software: CADCAM, Solid Works or equivalent Steel
Fabrication experience: Pneumatic systems, conveyor drives / transmissions
Control and safety systems and components
Temperature control systems
Pneumatic systems for conveyors, drives and transmissions
PLC and PID system software Commissioning experience
Layout drawings are produced in Solid Works and Corel Draw to set out the design concept.
A layout drawing is then made to meet the customer’s requirements.
Following an agreement, a drawing is made showing foundations and installation details.
Control and safety systems
For hard wired control panels, wiring diagrams with parts lists are produced by the electrical engineer. The contractor will make AutoCAD drawings for approval and inclusion in the Operation Manual. For PLC controlled ovens, software is provided by a specialist contractor
