Moisture measurement drastically reduces gas consumption

Save efficiently on energy with targeted moisture measurement when drying for example grain, animal feed pellets, sand and sewage sludge pellets Gas is used in a huge variation of dryers. The consumption of natural gas as a primary energy source has been standard for many years. It has even been promoted as a bridge technology until the application of energetic-technological alternatives is qualified. Just recently, a customer from Saarland told me that he scrapped his oil tank last year and switched to gas. At the moment, he is facing another rise in gas prices. Help is needed here to optimise the use of this resource and possibly make intelligent savings. A calculation example from a comparable application: 1 m³ of gas is required to reduce the moisture content of 1 tonne of sand by 1%. With a throughput of 85 tonnes per hour and an average required reduction of 4 %, 340 m³ of gas are consumed per hour. Now the energy costs have doubled. Instead of EUR 350,000 for gas, EUR 700,000 is now required to operate this dryer. Plenty of money to fund an instrumentation. The installation of moisture determination

Moisture measurement in sawdust and wood chips/wood pellets

Using SONO-GS1 enables direct moisture measurement in the material, even at hard to reach places Drying bulk solids in belt dryers When drying bulk solids with belt dryers, an air-permeable belt is filled with the product to be dried. The height of the bulk solids on the belt and the dwell time in the dryer are defined based on the product type and properties, and the water volume to be removed. By adjusting the dwell time to the mean value, it is possible to compensate for a varying moisture content. This is necessary in the production of wood pellets, for example, because the quality is no longer guaranteed if the material is excessively dry, and operating times are put at risk if the material is too moist, provided the compactor closes. Benefits SONO-GS1 * Continuous recording and monitoring of moisture content and temperature * Improved and more accurate process control during all work processes * Increased process stability and thus lower scrap rates * Cost savings due to increased energy efficiency (due to less overdrying) Overdrying or underdrying

Fast and precise moisture measurement in screw conveyors

Representative conditions and decent material flowin order to actually measure the process and no artificial accumulations of material. In order to reliably measure in bulk solids, it is necessary to determine an installation spot maintaining representative conditions and a decent material flow in the measuring field in front of the probe in order to actually measure the process and no artificial accumulations of material. A favorable installation was realized when using a SONO-VARIO LD in Italy. The screw diameter is large enough to allow the 108 mm probe diameter to fit into the screw housing without restrictions in the geometry, causing dead ends of material flow. Typically, the probe of choice would be a SONO-MIX Mini LD or even the larger SONO-GS1, as their rectangular geometry qualifies for easier integration into existing layouts of screw conveyors and narrow threads.

Applications and advantages of TRIME technology

Since 2023, we have a dedicated ATEX product portfolio in the specification: ATEX Directive 2014/34/EU | Ex II 2 D Ex tb IIIC T75°C Db according to EPS 20 ATEX 1 237. What is special about the TRIME method is that the measuring volume of the probe completely penetrates the adjacent material. In this way, not only measured values for surface moisture are determined. In contrast, measured values for representative bulk volumes in the process are transparent. In addition, there is no need for complex and error-prone bypass designs when using our TRIME systems. Since the end of last year, we have a dedicated ATEX product portfolio in the specification: ATEX Directive 2014/34/EU | Ex II 2 D Ex tb IIIC T75°C Db according to EPS 20 ATEX 1 237. Advantages of TRIME technology * Grain moisture and product moisture measurement directly in the dryer * Inline measurement in the process at up to 130°C * Reduced working time and higher process transparency through continuous measurement * Cost savings, since time-consuming post-treatments in the event of over- or under-drying become superfluous * Measuring ranges up to 70% humidity *

Phenomenon of shrinking bulk solids in silos

Have you ever experienced mystery? A container has been filled with bulk material, after some time the level was checked again and it has decreased. Astonishingly, nothing had been removed? Actually, this sounds familiar to all of us, doesn´t it? The flour in mum´s storage tin has changed its level over time along with flow characteristics. When turning the can upside down - the flour still stays unperturbed. What happened? The flour has settled, the air in the gaps has escaped, the filling level has decreased and the bulk density has increased. Bulk solids specialists refer to this observation as the ”time consolidation of bulk solids”, which is important for silo design and the dimensioning of discharging systems. Another key variable in the design of the silo and the peripheral technology is the moisture content of the bulk material. This can be determined, using various standard methods of sampling and oven drying, drying scales or sophisticated electronic measuring methods. We have been offering measurement technology for bulk solids since the 1990s. The underlying TRIME technology has been continuously improved over the last 40 years
