Máquina automatizada de congelación para el proceso de ultracongelación de alimentos

Abstract

This paper deals with the design and development of an automated freezing machine for the ultra-freezing process of foodstuffs. In the context of high competitiveness and technological advances, manufacturing companies need to modernize their operations. This project focuses on the implementation of control systems and production flexibilities. The research includes a detailed analysis of the refrigeration system, from the desing of the freezing tunnel to the implementation of a PLC for its control. The tunnel freezer operates an advanced process in which products are exposed to cold air streams at controlled speeds, allowing for a rapid and uniform temperature reduction. Results show that the developed system can reach ultra-low temperatures in record times, significantly reducing operating costs and increasing productivity. In tests, the machine was able to freeze food products in an average time of 12 minutes, guaranteeing optimal preservation of quality and freshness. In conclusion, the developed blast freezing machine represents a significant breakthrough in the food industry, offering tangible benefits in terms of quality, productivity and sustainability.
