Automação de um túnel de congelamento de hambúrguer

Abstract

This paper presents the design and implementation of an automated tunnel freezing hamburger. You Automation consist of a new electrical control panel, which will trigger a conveyor hamburger and fans to cool the freezing tunnel. In automating electrical panel was installed a Siemens PLC LOGO 12/24RC, and program operating motor drives the belt in three different modes which are: hygiene (fixed speed), normal production (variable speed) and direct start, and the motor drive belt cleaning mode and normal production is done via a frequency inverter. The temperature inside the tunnel is around -24 ° C, and is controlled by a temperature controller Full Gauge TC900Ri. This controller drives two fans. With automation was also changed the model of inductive sensors security conveyor belt and chain drive.
