Desenvolvimento de uma mesa chopeira de autoatendimento

Abstract

The development and evolution of automation to increase interactivity with customers and maximize profits in business establishments is rapidly gaining momentum. The present work aims at the development of a self-service chopp machine, intended for bars and restaurants that have scratched the beer as one of its services. For the work, tools such as temperature sensor, flow sensor and microcontroller were used to have the automation of the equipment. The results generated that served as data base were obtained during the test with the passage of water in the machine of chopp, being after that, used in the final adjustments for the test with beer, due to the latter having as characteristic, the presence of CO₂. Each phase of assembly and preparation of the project was separated in phases, where we first had the material and the necessary costs, after that, the construction of the cooling base and finally the programming, where the sensors and microcontrollers were organized to carry out a work in common. It was observed after the tests, that in order not to freeze the chopp in the coil, it is necessary that an antifreeze liquid is distributed around it, without formation of ice sheet and improving the control of temperature by the sensor. Through the liquid collected at the output of the equipment and the data recorded by the controllers regarding temperature and flow, it was observed that the generated results were satisfactory for a requirement of low flow. As the instruments we have at the time the work was developed are not all the most suitable for working with the draft, it is difficult to advance the efficiency of the equipment. In order for the process of withdrawing the beverage to take place in full, it was necessary to adapt some parts to meet the demand of the work, such as connections, flow sensors and arrangement of taps in a certain way that there is no loss of liquid transfer between the coil.
