Diseño y construcción de una freidora industrial circular a gas semi-automatizada con brazo removedor y sistema de fritura agua-aceite para la elaboración de snacks de papa

Abstract

The company "Proveedora Industrial" seeks to increase its line of potato snack fryers distinguished by its unique heating system, unlike conventional fryers available on the market. Therefore, the objective of this technical project is to carry out the design and construction of a semi-automated circular gas-powered industrial fryer equipped with a stirrer arm and a water-oil frying system. A methodology based on the DIN VDI 2225 standard was adopted to select the fryer design parameters. The proposed fryer has a capacity of 60 liters of oil and 15 liters of water. Its design incorporated a heating system using guitar-type burners. In addition, it is equipped with a remover arm consisting of 5 "L"-shaped paddles designed to prevent potatoes from sticking. The arm structure was designed using finite element techniques. To ensure food grade and avoid corrosion, select AISI 304 stainless steel as the construction material. The fryer has a heat capacity of 230,000 BTU/h and uses four burners controlled by a millivolt valve. The remover arm has an angular speed of 25 RPM and is driven by a 0.25 Hp single-phase reducer motor. Consequently, it is concluded that, with the heating capacity of 60 liters of oil, the maximum production reaches 30 kg/h. The heating process to 180°C takes approximately 30 minutes, and decreasing the temperature in 20°C intervals requires about 5 minutes. The resulting snacks have a golden color, adequate shape, and resistance and maintain these characteristics in 50 g containers, ensuring the final product's quality.
