At a glance  The control system for the bread baking oven meets three specific requirements: - temperature control across four different temperature zones - speed control on the conveyor carrying the loaves through the oven - and an HMI to monitor the process.  The selection of established, reliable components and careful programming, were key in delivering a low-maintenance design.

Speed control on the conveyor belt is also closely linked to the finished quality of the bread. tuning function of the DTC1000/2000 played a large part in ensuring that bakers can deliver a quality product in every batch, by providing excellent temperature control,” said Victor Ogedegbe, Field Application Engineer at Delta. Toma Draganov, Automation Engineer at Mechatronics Ltd, said: “Construction of the bread furnace was simplified by the availability of components that are interoperable and fulfilled the requirements set out by our customers. Accurate temperature control was most critical for us, and the Delta team’s support was essential in configuring the DTC1000/2000 auto-tuning function. This assistance contributed to the project moving from the initial design stage to full production in just seven months.” □

This project highlighted the skill required of bakers and engineers in creating a machine that delivers the perfect loaf in every batch.

New graphic operation terminals

Mitsubishi Electric has launched two new Graphic Operation Terminals (GOTs) as the latest addition to its GOT2000 Series Wide Model line-up. The 12.1-inch widescreen models, which feature narrow bezels and frame colours of smart silver (GT2512-WXTSD) or cool black (GT2512-WXTBD), will help meet customers’ needs for a wider screen to show more information in factory, process, utility and other automation applications. The models also feature various interfaces, including two Ethernet ports which facilitate the connection of

12.1, 10.4 and 8.4 inch sizes. The sheets help reduce the need for disinfection by adopting SIAA-certified sheets (evaluated in accordance with ISO 22196 and ISO 21702 standards). The sheets, which use RIKEN TECHNOS’ RIKEGUARD ® , are proven to inactivate 99.99% of viruses and reduce bacterial growth to less than 1/100, with 10+ years of performance in typical environments.

Ethernet cables. Additionally, they can support remote connection in cases where user access may be restricted. Remote connection functions such as SoftGOT enable remote maintenance via access to the local GOT screen and operators can obtain live data using GOT Mobile. Another benefit to support safe working practices, is the option of including new antibacterial, antiviral protection sheets for standard GT27 and GT25 GOTs in
