Operating at the forefront of food engineering, PMG Engineering offers comprehensive engineering design, procurement, contracting, and construction supervision services. Our goal is to assist businesses in creating state-of-the-art food factories. With expertise spanning food processing plant design, food plant engineering, and food manufacturing consultancy, we deliver tailored solutions to meet specific industry needs.

Major Electrical Equipment

Major electrical equipment forms the backbone of a food processing plant's infrastructure. These components manage and distribute electrical power efficiently, ensuring uninterrupted production.

  • MV/LV Switchgear/Switchboards: These units distribute power to various parts of the plant, maintaining operational safety and efficiency.
  • Transformers: Critical for altering voltage levels, transformers ensure that each section of the factory receives power suitable for its equipment.
  • Motor Control Centers/Panels: They regulate the operation of electric motors across the plant, optimizing control and automation.
  • Bus Bar Trunking & Cable Bus: Essential for transmitting electrical energy through the factory infrastructure.
  • Generators: Provide backup electricity, preventing downtime during power outages.
  • UPS (Uninterruptible Power Supplies): Safeguards vital electronics and systems from power interruptions and fluctuations.
  • Power Factor Correction Equipment: Comprising capacitors, controllers, and contactors, these enhance electrical efficiency.
  • Variable Frequency Drives (VFDs): VFDs grant precise control over motor speeds, accommodating variable production needs.
  • Electric Heat Trace: Maintains process temperature, preventing freezing or solidification of materials.

Minor Electrical Equipment

While considered commodity items, minor electrical equipment is vital for seamless factory operations. These components are typically covered in a general electrical specification:

  • Cable/Wire and Termination Kits: Facilitate connections and extensions within the plant's electrical framework.
  • Cable Tray: Organizes and supports electrical cables, ensuring they are protected and efficiently arranged.
  • Conduit and Conduit Fittings: Provide protective casings for electrical wiring, imperative for safety and durability.
  • Termination/Junction Boxes: Crucial for safely connecting and branching off cables.
  • Safety/Disconnect Switches: Enable manual override and disconnecting of circuits for maintenance.
  • Receptacles and Light Switches: Essential for day-to-day operations, facilitating access to power and lighting control.
  • Lighting Fixtures: Provide necessary illumination, ensuring a safe and efficient working environment.

Conclusion

The strategic incorporation of major and minor electrical equipment is central to the successful design and operation of food processing plants. With PMG Engineering's expertise as food manufacturing consultants and food engineering advisors, businesses can ensure that their electrical infrastructure supports optimal performance and allows for scalable growth.

Frequently asked
What counts as major electrical equipment in a food processing plant?
Major electrical equipment forms the backbone of a food processing plant's power infrastructure. It includes MV/LV switchgear and switchboards, transformers, motor control centres and panels, bus bar trunking and cable bus, generators, UPS units, power factor correction equipment, variable frequency drives (VFDs) and electric heat trace. These components manage and distribute electrical power efficiently so production runs without interruption.
Which minor electrical items should our general electrical specification cover?
Minor electrical equipment is usually treated as commodity items and captured in a general electrical specification. For a food factory this covers cable and wire with termination kits, cable tray, conduit and conduit fittings, termination and junction boxes, safety or disconnect switches, receptacles and light switches, and lighting fixtures. Though minor, these components are vital for seamless factory operations.
Why would we install VFDs on food process motors?
Variable Frequency Drives grant precise control over motor speeds in a food processing plant, so equipment can accommodate variable production needs rather than running at a single fixed speed. PMG Engineering treats VFDs as major electrical equipment, specified alongside motor control centres and panels that regulate the operation of electric motors across the plant for better control and automation.
How do we protect production against power outages and fluctuations?
Two items handle this in food factory design. Generators provide backup electricity, preventing downtime during power outages. UPS (Uninterruptible Power Supplies) safeguard vital electronics and systems from power interruptions and fluctuations. Both are classed as major electrical equipment and are specified as part of the plant's power distribution backbone so production continues uninterrupted.
What is electric heat trace used for in a food plant?
Electric heat trace maintains process temperature in a food processing plant, preventing the freezing or solidification of materials in lines and vessels. PMG Engineering specifies it as major electrical equipment, meaning it is engineered into the plant's power distribution design rather than treated as a commodity item under the general electrical specification.
Why do transformers and switchgear matter for a new food factory build?
MV/LV switchgear and switchboards distribute power to the various parts of a food plant while maintaining operational safety and efficiency. Transformers alter voltage levels so each section of the factory receives power suitable for its equipment. Together with bus bar trunking and cable bus, which transmit electrical energy through the factory infrastructure, they form the core of the plant's electrical distribution.
