1. CAD Computer Aided Design

2. Computer Aided Design Computer-aided design (CAD) is the use of computer technology for the design of objects, real or virtual. The design elements include: Packaging design Bacterial modelling Nutritional analysis

3. Computer Aided Design Packages

4. CAD - Packaging/ Product Design Designers can produce 2D/3D images (‘virtual reality’) of new food products and packaging The ideas can be seen by others in other parts of the office or even the world! Changes or modifications can be made on screen

5. CAD CAD can be used for adding pictures to packaging design/artwork Scanned images Digital photographs Clipart

6. CAD - Product Development CAD packages can also be used for Product Development. Spider Diagram Packaging nets Food labels Design ideas Star diagrams

7. CAD - Databases DATABASE - A collection of costs and items that can be accessed and searched through a spreadsheet. E.g. Using spreadsheets to cost products in product development COSTING

8. CAD – Nutritional Databases Nutritional modelling can be carried out using computer packages to create labels and nutritional data

9. CAD -Spreadsheets Spreadsheets are used to create: PRODUCT COSTINGS SCALING UP PRODUCT RECIPES STOCK CONTROL

10. CAD CAD can also be used for : Planning production flow charts Research and sales forecasting Modelling bacterial growth

11. Advantages of using CAD in the food industry Mathematical work is done speedily and with great accuracy. Computers allow designers to work quickly and accurately ‘Modelling’ saves money for manufacturers Designers can model ideas without having to produce a real dish!

12. CAM: Computer Aided Manufacture

13. Computer Aided Manufacture (CAM) - Definition The process of using specialised computers to control and monitor and adjust food processing machinery

14. CAM – Computer Aided Manufacture Food manufacturers use computers in many of the stages of production because they: Do not make mistakes Can run all day everyday without tea breaks! Save on labour costs

15. CAM – Computer Aided Manufacture Remove human error Assess thousands of products in minutes Detect things that the human eye cannot see!

16. CAM - Uses in manufacture Cam includes: Oven thermostats Oven temperature and temperature adjustment Weighing and measuring control Rate at which ingredient is added Amount of mixture coating being used Timing of mixing, kneading, stirring, combining Speed of a conveyor belt or other machinery Metal detector See CAD/CAM in food industry supplementing sheet for further information

17. ICT and CAM in single item production Microwave ovens Timers Bread makers Edible icing printer

18. Computer Numerical Control (CNC) CNC Means controlling machines using numbers and digital information Equipment required for the system in highly sophisticated and very expensive CAM systems use CNC machinery to carry out tasks in the production processes

19. Computer Numerical Control (CNC) – Cont... CAM systems use CNC machinery to carry out tasks in the production processes. Cad software can be used to drive CNC machines, e.g. Card cutters for packaging The benefits of using CNC include the following: - increased speed and accuracy - increases flexibility - continuous operations -economical to operate

20. Example of CNC Robot! This is a piece of equipment that is computer driven and mimics the skills of a human being Robots used for ‘pick and place’ operations e.g. Packing biscuits into a tray Stacking boxes

21. Computed Integrated Manufacture (CIM) A system in which all the stages of in a food manufacture processes are integrated and linked and controlled by computer systems High volume products such as bread, cereals and snack foods use CIM systems. They are essential because: They produce high volumes quickly They are highly accurate Consistent result
