Variance in the size of raw potatoes is a common issue faced by potato chip manufacturers. To overcome this problem, processors are incorporating a system called a ‘Grader-Halver’ into their processing lines. This cost-effective solution from Heat and Control is designed to consistently grade potatoes according to size, and then halves any that are larger than the predetermined size.
How it works Grading size is easily adjusted at any time during the production process and can be adjusted to a minimal size before rejecting very small potatoes, and foreign objects. This improves the grading process resulting in final (in bag) product consistency. Most importantly, this process stops chips from getting stuck in the former of the bagmaker when packaging snack-size packs.
In the processing line, the Grader-Halver fits in after the peelers, and before the inspection and trim table (rollers). The system has a rugged stainless-steel frame, adjustable multiple auger system with adjustable phasing, a roller conveyor, and slicing discs that halve larger potatoes. Potatoes are delivered to the infeed from the upstream equipment. Adjustable grading augers sort the product by size and over-sized product passes to a circular knife arrangement for halving. The larger-sized product continues along to the grading augers, while the undersized product falls through. Adjustment can be done during operation “ Consistent grading and halving Small product is captured along the full length of grading Clean and easy operation Ensure consistency of the final ‘in-bag product QUALITY CONTROL giving an instant assessment of grading size. The product that falls into the adjustable chute is directed into the FastBack 260E conveyor pan below the Grader-Halver and continues along the line.
The product that is larger than the maximum set size passes to the roller conveyor which orients the product and transports it to the circular halving knives, which then halves the potatoes across the longest dimension. Halved product pieces fall from the circular knives onto a curved chute that carries them to the FastBack 260E conveyor pan to mix with the previously sorted smaller items that are in turn passed to downstream equipment for further processing. Features and Benefits • Consistent grading and halving
• Small product is captured along the full length of grading
• Clean and easy operation
• No water consumption is required during operation
• Low maintenance
• Safety guards prevent access during operation
