Your specialists for non-contact measurements

Based  on the online moisture measurement system MOCON with microwaves, we have developed a variant for online moisture measurement of tobacco.

During  the inspection of the finished product at the packaging exit, it is checked to what extent the moisture content of each pack of cigarettes on the roller complies with the specifications. Cigarette packs are inspected in the warehouse to avoid enormous economic losses due to mildew during storage.

Product specification

Online tobacco moisture measurement using microwaves

Description

MOCON-TAB  is an online measuring system for determining the moisture in tobacco using ultra-low frequency microwaves (925-980 MHz).

The  average moisture content of the entire cigarette pack and the moisture content per unit section of the cigarette pack are determined.

The  contactless measurement has no influence on the production process.

Per  second high test accuracy and repeatability of up to 0.1%, can be 8 data recorded and displayed as a bar graph in a trend diagram.

Details

Software  calibration and operation are simple and convenient.

The  software can immediately display the moisture data in real time and display the internal moisture of the cigarette pack.

8  different tobacco qualities can be saved and 8 linear storage channels can be supported.

The  measuring system offers you multi-port output, 4-20 mA, RS232 and other options for data exchange with PLC or DCS systems.

Quality  control can be provided with real-time moisture data remotely to adjust the process in time and meet the required quality requirements.

Moisture  measuring range:
● generally 0-60% (depending on the application)
● waste paper 0-30%, wood chips 40-55%
● strongly dependent on the product for cigarette packs and cotton
● Resolution: 0.01%

Average  absolute measurement error:
● waste paper 1%
● Wood chips 2%

RGI

Measuring principle

Microwaves  are characterized by their ability to penetrate non-conductive materials. Matter has a bipolar molecular structure (like water).

When  microwaves pass through the material, the electromagnetic field causes resonance and the microwaves lose part of the energy, this energy loss increasing with increasing moisture content of the material until the energy reaches the other side of the material.

Water  not only absorbs energy, but also reflects microwave energy. These two microwave properties are used to measure the moisture content.

During  the material transport, the material that is in the area between the microwave transmitter and the receiver probe is tested, the energy that ultimately reaches the microwave receiver probe being less than the originally emitted due to the moisture content, so that from this difference the degree of moisture can be determined.

In  the microwave reflection process, the steps are the same except that the transmitter probe and the receiver probe are installed on the same side of the material.

That's what makes RGI products so special
