The moisture balances analyze the dry sample that remains after a practice of drying with infrared energy of the total substance, first weighed to reduce the moisture of the wet heavy mass. During drying, the deduction of moisture content can be seen on the screen. They are also ideal equipment to treat moisture, dry matter or the consistency of volatile and fixed materials or substances with precision.
In the same way, these are used mainly in the industrial sector, to quickly analyze pastes, masses, wood, adhesives, powders, etc., both in the production and in the control of entry of goods. The weighing system possesses all the properties of modern scales.
Finally, with the use of this equipment, it will be possible to quickly and accurately analyze the moisture of the most diverse bulk materials, powders, food, wood pellets or pasta.
Principle of measuring Humidity Balances
The detection of moisture content in different materials is an important property element and plays a very significant role in sectors such as technical and economic. Using the thermogravimetric method, it determines the weight loss through the drying process, where the sample of material must be weighed before and after drying. The difference in weights is established with respect to the starting weight or the final weight after drying.
In this way, the amount of moisture in the materials with the thermogravimetric method, are enclosed in the measure of all the components of the sample of material that can change their physical state, and that are involved in weight loss. In this measurement, all types of volatile elements, such as alcohols, aromatic substances, base diluents and other substances originating from thermal decomposition, should be taken into account.
Applications of Humidity Balance
The moisture balance is used especially in the manufacture of food, in the manufacture of construction materials, in the chemical sector, in biotechnology, in the wood industry, in the pharmaceutical industry, in the environment and in ensuring the quality of materials. It can also be used as a laboratory scale to determine the weight of the materials (without the drying process).
The objective of this description is to know practical aspects of moisture analysis, which allows using the balance as a 100% work tool.
This moisture balance, after weighing the wet substance, applies heat by quartz foci until the moisture completely evaporates, now can be calculated on the difference of both weights (wet and dry), the moisture it contains.
Development of Calibration Methods
The determination of the appropriate calibration method for an equipment will depend largely on the working principle, and through the course will be the gravimetric method (drying in an air oven), because it allows to give traceability to the commonly used instruments in the industrial field and additionally allows calibrating multiple equipment simultaneously.
For this purpose, adjustments should be made to the adjustment measures, such as drying temperature, drying schedule and sample weight and sample handling. This is the result of the humidity balance, as a perfect measuring device to establish the exact humidity, the weight of the anhydrous substance or the consistencies of the solid materials and evaporated substances.
