The new models are particularly ideal for meat, poultry, fish and seafood, which cannot be moved by feeder vibration, or where manual product feeding is not economically viable. Because of the very sticky nature of these products, most current weighing systems are either manual or based on a linear design that relies on operators to direct and control the supply and flow of product.
The Ishida Screw Feed design, by comparison, utilises the familiar circular multi-head weigher layout but incorporates unique rotating corkscrews to replace the traditionally used radial feed troughs. The use of the screws provide a powerful, controlled and fully automatic product feed to the pool, and weigh hoppers.
Ishida has developed two screw feeder models. The first features three litre, stepper motor driven anti-stick metal hoppers and is particularly suitable for larger target weights and larger piece size applications, including on-the-bone products. It has a top speed of 80wpm. The second version incorporates 1.5 litre pneumatic driven plastic scraper hoppers with a maximum speed of 60 wpm.
Both models incorporate the unique calculation processing software of the Ishida R-Series. Ishida says they will easily double packing speeds for the stickiest products, while significantly reducing giveaway thanks to their outstanding accuracy. As a result, weighing speeds and accuracy show an improvement of approximately 20% compared with the best linear weighing systems, says the company.
A user-friendly Remote Control Unit (RCU) allows ease of set up and changeovers to minimise downtime, and provides detailed production information. The new Screw Feed weigher range is another innovative approach to fresh food weighing.
