The CBS 20 is a general purpose, low-cost automatic batching system, with the facility to control up to 24 ingredients using up to 3 weigh hoppers and 4 flow meters.

The system provides up to 200 recipes and any quantity can be batched.

Automatic in-flight compensation ensures accurate weighing and dispensing. The overshoot caused by the material that is "in flight" and delays in doors closing etc. is automatically compensated for. Two-speed feeds and "jogs" can be selected to cater for difficult materials.

A downstream mixer can be controlled with preset mixer times, and automatic discharge. Materials can be ribbon fed to the mixer to assist the mixing process.

Automatic compensation for the moisture content of the materials fed to the weigh hoppers is provided. Control of the moisture content of batch in the mixer can be provided.

"Bin skipping" is provided where if a bin runs out of material and that material is also in another bin then the new bin will be used.

A printout can be provided for each batch showing time and date, target and actual ingredients, recipe number, quantity, and batch number.

Optionally, a delivery docket can be printed on a second printer. A database for 100 customers / sites is provided. The total amount of each material batched automatically is recorded. Each batch can be recorded against one of ninety job numbers.

Control can be provided for aggregate skip hoists and holding hoppers, dual door mixers, wet / dry leg control.

Automatic moisture compensation can be provided using bin probes, or probes in the mixer.
