Overview
The Marel Multihead Weigher deals with all infeed, sorting, mixing and weighing requirements. It automatically portions and packs food products into virtually any type of tray, thermo pack, bag, can, glass or box.
Products are dispensed into hoppers by vibrating feeders and weighed into exact portions.
Food items ideally batched with a Multihead Weigher include seafood mix, frozen fish fillets, IQF toppings, diced meat, poultry strips, nuggets, wings and drumsticks.
The Multihead Weigher can also be used by processors who need to make split or mix portions. The machine can be divided for use with two or three products, which enables split portions of three different products. The machine can also be divided for use with two packing lines.
The new Marel Multihead Weigher IQF Poultry
Based on many positive user experiences of the Multihead Weigher series, Marel has now developed an entirely new machine exclusively for the poultry industry. Robust, easy to use and designed for optimum throughput with minimum giveaway, the Marel Multihead Weigher IQF Poultry handles poultry cuts at high capacity and with great accuracy.
The MHW-IQF Poultry is designed for the rapid, accurate batching of frozen poultry products. The unit's 14 large hoppers, each with a capacity of 7 litres, are specifically designed to handle the toughness of frozen products, with a high throughput of up to 60 batches/min.
Features
- High-quality touch screen
- Hermetically sealed load cells
- Consistent, maximum-capacity flow of products, thanks to Automatic Feeder Adjustment (AFA) technology
- Ethernet connection
Marel is able to supply and integrate a wide range of standard and customised conveyors, vibrators, screw feeders and lifts – as well as specially engineered systems to meet individual requirements.
Distribution tools

Software
Automatic Feeder Adjustment (AFA)
The key to weighing accuracy and high production capacity is an effective vibratory feed system.
To make sure these vibratory feeders operate at maximum efficiency, it is crucial that each feeder vibrates at its own specific resonance frequency at all times. This frequency changes over time, however, due to wear and tear in the feeder system as well as normal fluctuations in temperature and humidity.
The AFA technology therefore automatically ensures that each individual feeder vibrates at its own unique resonance frequency.
Key features of AFA:
- Extremely fast self-adjustment – it takes less than 30 seconds to optimise the frequency of all 10, 14 or 18 vibratory feeders
- Easy to use - no need to give operators any special training - simply push a button
- Driver frequency is far more accurate than when using mechanical adjustment
- Unaffected by any fluctuations in electrical voltage.
