For the Grading, Classifying and Equalizing of unpacked food products

LIEBEL graders of the USS-4, USS-6, USS-8 and USS-12 type are made for applications with high throughput especially within the area of meat and fish production. The assembly of fixed weight batches, consisting of products with different individual weights, as well as a weight specific classification into different weight categories, can be carried out – if necessary simultaneously on the same machine.
Our industrial standards guarantee excellent precision together with unsurpassed reliability. Stainless steel finishings with disguised weighing-units provide solutions for both, dry and wet production areas (IP 66 protection). Polished stainless steel surfaces, cantilever transport-belts and a high ground clearance permit excellent cleaning properties. Aside from that LIEBEL graders are known for their minimum space requirements.
LIEBEL graders are equipped with an independent weighing unit based on the LWS 1500 checkweigher series and the UNISORT sorting-software. The operating unit affords easy handling. Despite of the uncomplicated intuitive menu, the user has multiple operating and statistical options (see Data Sheets).
A large variety of technical options allow each USS machine to be adapted to specific needs. This includes bag filling devices, roller containers, automatic delivery to bag-filling machines or tild conveyer systems for most gentle “no-touch” sorting – just to mention a few.
It is also possible to use USS graders within the non-food industry (see our non-food demonstration of a sorting machine for metal hangers).
Attention: Graders (Sorting systems of the USS type - Universal Sorting Systems) are generally used for both, sorting as well as equalizing of unpacked products. Equalizing machines of the UES type (Universal Equalizing Systems) are generally used for packed products in combination with a price labelling machine.

DETAILED DESCRIPTION OF LIEBEL GRADERS

Depending on the difficulty of the sorting process, our graders are equipped with 4 to 12 channels. The decision as to which system to use, will be based on a previous software simulation. As a prerequisite for this simulation we ask our clients to send us a USS-Checklist together with specific weight data.


Videos are available in Windows-Media-Format. The current software version can be downloaded here.

   

USS 4 to 12 Channels Standard System
Unpacked or packed products - sorting is, aside from the criteria of weight, also possible for other criteria like pH-levels, color, size, etc...
