Food & Beverage Processing

CD Automation supplies SCR/thyristor power control for food and drink processes including baking and tunnel ovens, proofers, fryers and kettles, pasteurisers/UHT systems, CIP/SIP heaters, chocolate tempering and packaging shrink tunnels. REVO controllers help improve product consistency, support hygiene-focused designs and provide useful diagnostic and energy data to plant automation systems.

With REVO C for single zones, REVO-PN for compact multi-zone equipment, and REVO-PC, or REVO-DPU zone control for larger lines and utilities, we integrate with PLC and SCADA platforms using common fieldbuses to support OEMs and end-users across bakery, dairy, beverages, ready meals and confectionery.

Industry Overview – Electric Heating in Food & Drink

Food and drink manufacturers use electric heating in ovens, proofers, fryers, kettles, pasteurisers/UHT systems, CIP/SIP heaters, chocolate lines and packaging equipment. Stable, repeatable temperature control helps maintain product quality, microbiological safety and throughput, while efficient power delivery supports energy and sustainability objectives. Intelligent SCR power control can improve stability, help manage electrical load and provide data to plant automation and monitoring systems.

  • Baking & tunnel ovens
  • Proofers, retarders & low-temperature dryers
  • Fryers, kettles & cooking vessels
  • Pasteurisers, UHT/HTST & process loops
  • CIP/SIP heaters & electric boilers
  • Chocolate tempering systems & conches
  • Shrink tunnels & heat sealers
  • Hot-fill & aseptic transfer heating

Typical Pain Points & How We Solve Them

  • Temperature Uniformity & Product Quality
Baking, frying, cooking, tempering and pasteurisation processes are sensitive to temperature variation, which can affect texture, appearance, microbiological stability and shelf life.
Solution: REVO C, REVO-PN and REVO-PC-based architectures provide smoother power control to heaters and zones, helping to maintain consistent temperature profiles across ovens, kettles, pasteurisers and lines.
  • Hygiene, Washdown & Food Safety
Food and drink plants must maintain hygienic conditions and often use washdown regimes around production equipment.
Solution: By locating REVO power controllers in suitable panels and technical areas, the control system can be kept away from direct washdown while still providing accurate electric heating to hygienic process equipment.
  • Energy Costs in Heat-Intensive Processes
Ovens, fryers, kettles, CIP heaters and UHT/HTST systems can represent a significant portion of a site’s energy use.
Solution: Using appropriate firing modes, demand limiting and staged starts via REVO-PN and REVO-PC can help reduce electrical peaks and improve overall energy performance compared with basic on/off control.
  • Frequent Changeovers & SKU Complexity
Multiple recipes, formats and packaging configurations require predictable heating performance during changeovers and start-up.
Solution: Digitally controlled SCR power via REVO C or REVO-PC allows heating profiles to adjust quickly to new setpoints, helping to reduce start-up scrap and changeover time.
  • Downtime & Heater Reliability
Heater and wiring failures can cause downtime on critical assets such as tunnel ovens, pasteurisers or packaging lines.
Solution: Diagnostics like open or partial-load detection and current monitoring from REVO C and REVO-PC assist maintenance teams in identifying developing issues earlier.
  • Compliance, Traceability & Audit Support
Food manufacturers are asked to provide evidence of process conditions and equipment performance for audits and customer approvals.
Solution: When REVO controllers are connected to PLC or SCADA systems, power and alarm information can be logged alongside temperature data to support traceability and reporting.

Snapshot: Baking Tunnel & Pasteuriser Electric Control Upgrade

Problem: a bakery and ready-meal site using contactor-based tunnel oven control and a basic hot-water pasteuriser loop was experiencing temperature swings, long start-up times and limited information on heater performance and energy use.
Solution: the tunnel oven zones were re-controlled using a REVO-PC master with REVO-S zone controllers, while the pasteuriser hot-water heater skid was upgraded to REVO C (with optional expansion via REVO-PC + REVO-C for future loops). The line PLC now receives power, current and alarm data over a fieldbus connection and coordinates oven and pasteuriser setpoints with production recipes.
Result: more stable baking and pasteurisation temperatures, smoother start-up, improved batch consistency and better visibility of energy use and heater status for engineering and production teams (typical benefits achievable on similar upgrade projects).
