IN Brief:
- Roberts is investing £425,000 in refrigeration and X-ray precision portioning equipment.
- An earlier microwave tempering installation reduced a 72 hour process to around 20 minutes.
- The wider £750,000 programme targets same day production, improved yield, and lower energy consumption.
Roberts of Port Dinorwic is investing £425,000 in energy efficient refrigeration and X-ray precision portioning as part of a £750,000 manufacturing programme at its North Wales operation.
The company produces ready to cook meal components for restaurant groups, quick service operators, and food wholesalers. Its latest equipment follows a £300,000 microwave tempering installation that reduced a process previously taking 72 hours to around 20 minutes.
Conventional tempering often requires frozen meat to remain under controlled refrigerated conditions until its temperature rises sufficiently for slicing, portioning, marination, or further preparation. Product must be selected several days before use, occupying space and committing the production plan long before final customer demand is known.
Microwave tempering introduces energy through the product and raises its temperature much more quickly. Roberts can consequently retain material in stable frozen storage until closer to use, then prepare it for production during the same day.
Shorter lead times give planners more freedom to respond when order volumes or product priorities change. They also reduce the quantity of partially tempered meat waiting for a processing slot, where further delays can narrow the safe and usable production window.
The new X-ray portioning system will inspect the internal shape and composition of each piece before directing cuts with accuracy of approximately 1mm. Natural variation makes meat difficult to portion consistently from external dimensions alone, particularly where fat, bone, or thickness changes through the product.
Greater cutting accuracy can reduce giveaway while protecting compliance with customer specifications. When portions are sold at a fixed size or weight, processors frequently cut above the minimum to avoid underweight product, transferring additional meat without receiving extra revenue.
Faster preparation reshapes production planning
Roberts expects the equipment programme to save around £200,000 in energy each year, giving the investment an estimated payback below two years. Performance will depend on utilisation, maintenance, production mix, and the efficiency of the previous systems, but energy is being considered alongside labour, yield, and responsiveness.
Refrigeration is a major electrical load in meat processing because raw materials, work in progress, finished products, production rooms, and storage areas all require controlled temperatures. More efficient plant lowers direct consumption, while faster tempering reduces the time and space devoted to material moving gradually from frozen to process ready conditions.
The programme sits within a wider increase in automation across British pork and poultry processing, where yield control, cold storage, material handling, and line flexibility are receiving as much attention as simple throughput.
Reducing tempering from three days to minutes will only create the full benefit when downstream operations can accept the product. Cutting, marination, coating, cooking, packing, and despatch need available capacity, otherwise waiting time is merely transferred from tempering to another part of the factory.
Microwave processing also requires tight recipe control because absorption can vary with geometry, fat content, initial temperature, batch arrangement, and packaging. Validated programmes must reach the intended working temperature without creating local hot areas or beginning uncontrolled thawing at exposed surfaces.
The portioning system introduces different controls around calibration, blade condition, product presentation, and verification. X-ray data may improve the cut plan, but finished portions still require weight and dimensional checks to confirm that accuracy remains stable throughout production.
Maintenance becomes especially important when equipment removes a major bottleneck. A failure in tempering or portioning can now restrict several downstream activities, making spare parts, preventive work, remote support, and operator fault diagnosis central to the projected return.
The same principle applies to refrigeration. Efficiency gains must be balanced with resilience, particularly where a single upgraded system serves several production or storage areas. Monitoring, alarms, backup capacity, and emergency procedures protect material when faults occur outside staffed engineering hours.
Improved responsiveness can reduce finished goods inventory because orders can move from frozen raw material to completed product more quickly. It may also allow Roberts to accept shorter notice work, although rapid turnaround should not weaken ingredient checks, traceability, cleaning, or quality release procedures.
More precise portions strengthen the economics further at a time when meat costs remain volatile. A modest reduction in average giveaway can recover valuable material across thousands of portions, while improved shape consistency supports even cooking and more predictable presentation.
The programme connects speed, yield, and energy rather than treating each as a separate investment case. Microwave tempering releases time, X-ray cutting protects material value, and upgraded refrigeration lowers the cost of maintaining controlled conditions.
Once the equipment is fully integrated, Roberts will have a shorter and more responsive route from frozen stock to packed meal component. The operating return will be determined by how effectively scheduling, maintenance, quality, and downstream capacity use the time released from the former 72 hour tempering process.
