    Development of innovative commercial dishwasher using gas-heated water for energy efficiency

    Machines. Technologies. Materials., Vol. 16 (2022), Issue 6, pg(s) 192-194

    Commercial dishwashers are among the most important products for commercial kitchen personnel as they clean dirty products (plates, glasses, cutlery, etc.) in a short time (between 1 and 4 minutes according to the program). In recent years, customers’ demands for energy-saving products have been increasing. Therefore, instead of using the electrical energy to be obtained after the combustion of natural gas in power plants, the use of direct natural gas in a commercial dishwasher contributes to reducing the carbon footprint. In this study, the original design studies of the combustion system of the innovative commercial dishwasher prototype using water heated with gas were carried out. For the first time in our country, the system that enables the heating of water with gas was designed as a module other than the existing commercial dishwasher. An independent combustion system has been developed to provide easy use to other commercial dishwashers on the market. Simulation studies have been used effectively in the design verification phase in order to provide the most efficient combustion conditions for different gases (natural gas and LPG) in the original designed combustion system. Combustion analyses were carried out by parametric study for different operating conditions. In the innovative commercial dishwasher prototype that uses water heated with gas, optimum temperature values have been obtained for effective washing at the water inlet and water outlet points of the uniquely designed combustion system. As a result of the tests and evaluations, the most effective working range of the innovative prototype was determined.

    A new commercial dishwasher design using mineral additives in its drying system

    Machines. Technologies. Materials., Vol. 15 (2021), Issue 6, pg(s) 223-225

    Commercial dishwashers in different performance classes are used in all industrial kitchens. In contrast to existing commercial dishwashers, there is an increasing demand for products that use drying technology to meet customer wishes and needs. Various household dishwashers having zeolite mineral during drying prevents water droplets and detergent stains (including surfaces of plastic containers) on the surfaces of dishes and rinsing of sensitive products (crystal glass glasses, etc.). By pointing out that they prevent excess steam from spreading when opened, they highlight these products as environmentally friendly and value-adding compared to conventional household products. In this work, we developed a new commercial dishwasher prototype using a mineral in the drying process. Technical simulations and experiments are used during the development of our innovative prototype with a drying system using a mineral that stores moisture and converts it into thermal energy. This is the first prototype in commercial dishwashers with its innovative drying system.
