MW 4420

Cigarette & Filter Inspection System.

Check out our latest final quality inspection measurement solution for cigarettes and filters, the MW 4420.

The MW 4420 measurement station is ideal for controlling the quality of many different cigarettes, whether with or without filters, filter-tipped and multifilter.

Based on the microwave resonance technology, the system measures the moisture and density (Mass / weight) of tobacco and rods. What makes the solution unique is that moisture is measured independently of density (and vice versa). Moisture and density can be determined at the same time.

The test station detects moisture, weight and dense-end profile of a cigarette. In addition, the system thus is able to measure charcoal content and triacetin in cigarettes as well as NTRM (foreign bodies) and it can precisely detect the position and condition of aromatic capsules in filters or determine the different sections of a multifilter.

The integrated color touch screen and its self-explanatory user interface allow the system to accurately keep track of results in conformity with ISO 9000. The following details are read and kept: time, date, cigarette brand and make as well as minimum, maximum and average moisture and density values.

Results as mean values, standard deviation, minimum and maximum are shown graphically as an output to the screen and printer. Data can be exported to a USB memory stick for further processing by external programs such as spreadsheets. The Ethernet port allows integration into enterprise network, as appropriate.
