The content of this page is about fixed weight retail pre-packing and weighing scales solutions from Aja.
Aja has been at the forefront of providing Fixed Weight, Fixed Price, Case Ready retail pack weighing solutions since Fixed Weight, Fixed Price packs first appeared on the shelves of UK Supermarkets.
Multiweigh Fixed Weight Solutions
The Aja Yamato TDW ‘Selector’ Scale and SDW ‘Optima’ Multihead Weigher have over the last 15 years become industry standards in the meat, poultry, fish and produce sector for entry level, medium and high volume, fresh, frozen and value added difficult, delicate, fixed weight retail packs.
Multihead weighing has repeatedly proven to be the most accurate and effective way of controlling and minimising Give Away and handling awkward often sticky product by weight controllers.
Multihead combination weighing analyses all the individual piece weights in each hopper or pan and then calculates in which order/combination will the minimum give away be achieved. This is all being calculated in mille seconds with the high speed processor being constantly updated with new weights in which to calculate new pack combinations.
At any one time on say a 14 head weigher there are typically 11 or 12 real time weights from which to make a true and accurate combination. Multihead weighing is vastly superior to Linear systems which have only weigh head with possibly weighing combines
Both the TDW and SDW are user friendly, flexible, fully washdown to IP66.
Above: The ‘New’ TDW ‘Selector’ Scale 2102 will pack all day to 15 ppm with between 1% link TDW at 3% Give Away without the minimum of training and supervision.
SDW ‘Optima’ offers a higher level of automation, sophistication and speed with superior Give Away control by offering both average and nett minimum weight and superior software to optimise pack accuracy and weighing performance. Typical pack speed is 30 ppm with Give Away as low as 0.5%.

Thus ensuring pack and weight integrity. Ease of clean down for short runs and a emphasis on hygiene are all critical elements of the AWS and BWS weighers.

Typical Give Away can be as low as sub 1% with speeds up to 35ppm depending on model and product characteristics
