SAMMIC, S.A. manufactures different machinery for the food service industry including: potato peelers, mixers-beaters, vegetable processors, meat grinders, glassware-washing machines, dishwashing machines, vacuum-packed machines, etc. SAMMIC is a medium size Spanish company employing 130 persons, and achieved sales of 22,84 MEUR in 1.999.

The company is specialised in the design, manufacture, marketing and through life support of machinery for the food service industry. The product improved during this AE is the company's dishwashing machine supplied to catering business and communities such as hotels, restaurants, cafés and snack bars, through distributors and resellers of food service equipment.

Before the AE, the company used electromechanical cam based programmers to control the operation sequence of the dishwasher. The company had no experience in electronics with no knowledge of microcontroller based system design.

Thanks to the electronic technology SAMMIC can reduce the number of washing program controllers references used to control the wide range of dishwashers that the company produces. A more flexible and general control device has been obtained. The new washing program controller results in a more flexible solution with easier way to program and adjust washing cycles time. Additionally the electronic control system incorporates built-in fault diagnostics functions to make maintenance service even simpler.

One of the main competitiveness factor of SAMMIC's products is quality-price relationship. The new electronic washing program controller will allow the company to maintain their machines selling price and increase sales. Moreover, the company will extend the range of dishwasher's models with the incorporation of new machines offering additional functions, like decalcifying function.

The total cost of the AE was 37 KEUR and it was completed in 10,5 months. It is predicted that 240 additional units will be installed during the first year, and hence the payback period will be 1 year (15 months taking into account industrialisation costs). The company will achieve a ROI of 560% in relation to the project total investment.
