Prototipo de túnel de limpieza y secado automatizado de bandejas alimenticias utilizando un sistema de riego a alta presión

Abstract

For the present project, it was discovered that automated cleaning disinfects up to nine pieces in less than two minutes, representing only a tenth of manual washing. However, despite these technological advances in the food industry, tray sanitation still largely follows traditional methods. Therefore, the ongoing project aimed to develop a tunnel-style prototype that functions for both automated cleaning and drying of food trays using a high-pressure irrigation system, providing more efficient processes regarding water reuse and increased operational productivity. The design of this prototype consists of a tunnel with two pairs of coils inside. The first group is activated by the main sensor, which expels water under pressure for soaping, while the second group is for rinsing the trays. It is worth mentioning that all water used in this process was collected in containers placed under the tunnel for reuse. For the final drying stage, a blower and a trumpet were implemented to eliminate moisture from the initial process using pressurized air. Furthermore, the results showed that the time reduction indicator was met, approximately one minute and forty seconds, allowing us to detect clean and dry trays. Additionally, it was determined that the amount of water used for the washing process exceeded two liters because this value would not provide sufficient pressure for proper functioning. However, by recycling the water, the process could be sustained. Therefore, it is concluded that the creation of this machine allowed for the efficient use of resources, improved operational efficiency, and enhanced the quality of the washing process, providing high percentages of cleaning and drying and ensuring high standards for food products.
