In commercial kitchens, deep fryers are essential for frying various foods, particularly frozen products. These appliances, available in multiple models and capacities, typically use gas or electricity and utilize significant amounts of cooking oil. For instance, a standard commercial deep fryer may have a cooking chamber with a capacity of 22 liters of oil. However, over time and with repeated use, the quality of the cooking oil deteriorates, leading to the formation of waste oil. This waste oil affects the quality of fried foods and presents significant environmental challenges. The improper disposal of waste oil contributes to environmental pollution, necessitating businesses’ careful management and disposal. In response to these concerns, our research and development (R&D) efforts have focused on designing and developing a novel eco-friendly commercial deep fryer with an integrated filter system. Unlike existing models in our product range, this innovative deep fryer is designed to achieve energy savings and reduce the amount of waste oil produced. Specifically, the new deep fryer has demonstrated energy savings of at least 25% compared to our current models. Additionally, this fryer can operate using alternative solid oil, offering further flexibility and sustainability in commercial kitchen operations.

Commercial kitchen cookers are widely used in various capacities and fuels (natural gas, LPG, etc.). Depending on the decrease in fossil resources and the increase in energy needs, several researches in alternative fuels have been accelerated. Especially in recent years, R&D studies and investments in renewable and environmentally friendly energy sources (solar, wind, biomass etc.) have increased. In line with the EU’s Renewable Energy Directive (Directive 2018/2001/EU), it is aimed to use at least 32% renewable energy sources by 2030. Significant R&D gains have been achieved with the cooperation of industry-university in order to use hydrogen as clean energy as an environmentally friendly alternative energy source for commercial kitchens. In this work, we developed an environmentally friendly commercial kitchen cooker prototype using hydrogen with a uniquely designed burner has been achieved. Results show that using hydrogen in commercial kitchens is promising if hydrogen safety is locally possible.
