Renewable energy source: those sources of energy that are sustainable and have less environmental impacts. Nowadays renewable energy like solar energy is gaining importance are preferred over conventional sources due to its different advantages. One of these applications is solar cooking. There are many designs of solar cookers available in the market, but only a few of them became commercial. Therefore, our goal is to design a simple, compact and portable solar fryer. Based on the design of a prototype will be manufactured and experienced and its performance will be tabulated along with the performance of SK-14. Based on the results, ie, efficiency will be determined and it will be concluded that the solar portable fryer is applicable for commercial purposes.

The solar cooker is the simplest and quickest way to cook food without consuming fuel or heating the kitchen. Paraboloidal solar dish type cooker. A specially designed paraboloidal reflector surface concentrates beam radiation and concentrates it at a point where a cylindrical brass vessel containing food material is placed. A commercial solar kitchen SK14 developed by EG Solar, a German NGO, is being manufactured in India recently. The vessel receives the concentrated solar radiation directly. The reflector is adjusted periodically to track the sun. You can get a fairly high temperature of about 450 ° C and you can cook a variety of foods that require boiling, baking and frying for 10-15 people. You can save fuel for up to 10 cylinders of LPG per year in full use. The cooking time is approximately 20-30 minutes. The approximate cost of the kitchen is Rs 8,500. In our project instead of the food material that holds a liter of water in the container and we have temperature up to 50 degrees Celsius.
