APPLICATION REPORT Food & Beverage Granulated sugar level measurement • Storage of sugar of various grain sizes in concrete silos • Non-contact radar measurement of medium that forms dust • Automated inventory management of sugar supplies 1. Background The Pfeifer & Langen Group is one of the largest sugar producers in Germany. In addition to several sugar plants, this long-established company also has plant locations for storage and logistics, one of which is located in Grevenbroich in the Lower Rhine region. Here, granulated sugar from the sugar factories is stored in four concrete silos. The...

APPLICATION REPORT 3. KROHNE solution The customer decided on the OPTIWAVE 6300 C non-contact radar level transmitter. Boasting a 24...26 GHz FMCW radar, the measuring device is designed for use in extremely dusty atmospheres. It features a patented, elliptical drop antenna that does not clog up, even in the presence of extremely adhesive media such as sticky sugar dust. Due to the measuring height and the low dielectric constant of the medium, in this application the large drop antenna (DN 150) made of polypropylene (PP) was selected. It was installed using a G1 ½ process connection. The devices...

Food & Beverage APPLICATION NOTEMeasuring layer thickness in a centrifuge • Continuous measurement of layer thickness when filling centrifuge • Controlling the layer thickness during the spin process • Automated filling process 1. Background A sugar producer fills a centrifuge with hot molasses sugar to press the moisture out of the molasses at high speed. The thickness of the layer of molasses on the wall of the centrifuge is reduced in the process. The layer thickness is thus a measurement of the moisture content of the layer of molasses. 2. Measurement requirements The centrifuge is the shape...

APPLICATION NOTE 3. KROHNE solution For this type of application, KROHNE supplied 4 OPTIWAVE 7300 C radar level measuring devices with DN 50 / 2" horn antennas and G 1½" connection. The existing constructions were used for mounting. Thanks to FMCW radar technology, the OPTIWAVE level meters measure over a very wide dynamic range. That is why neither the minimally reflective surface of the molasses layer nor the high speed of the centrifuge when filling and during the spinning process affect the measurement of the layer thickness. Following each spin cycle, all parts that come into contact with...

APPLICATION NOTE Food & Beverage Measurement of Brix and mass flow in sugar production • Determining the weight and sugar concentration in sugar cane juice • Measuring without pressure drop or blockage of the measuring tube • Cost-effective alternative to weighbridges and laboratory analysis 1. Background A sugar manufacturer produces sugar from sugar cane juice. After harvesting, the sugar cane is crushed in presses to obtain the sugar cane juice. This juice is then weighed before it is made ready for further processing. In the past, measuring the weight of juice was done by large weighbridges...

KROHNE supplied the Coriolis mass flowmeter OPTIMASS 7300 C. The meter was installed between the sugar cane press and the storage tanks. It measures the mass flow of the sugar cane juice as well as the sugar concentration (the Brix value) by way of integrated density measurement. The single straight tube design makes the OPTIMASS 7300 the meter of choice for measuring viscous liquids such as sugar without the risk of blockages or pressure loss. The OPTIMASS 73000 has enabled the sugar producer to reduce investment and operating costs in sugar processing significantly through the elimination of...

Food & Beverage APPLICATION REPORT Custody transfer measurement of sugary syrup • Measuring system as per MID MI-005 • Mass flow measurement of sugary syrup • Space-saving installation with straight tube design 1. Background UNIFERM is a domestic and international supplier of ingredients for bakeries. The company supplies the bakery trade and baking industry with a comprehensive range of products including baking yeast, baking agents for bread and rolls, baking agents for fine pastries and separating agents. 2. Measurement requirements Measuring system Sugary syrup is used as a raw material in...

KROHNE provided a Coriolis mass flowmeter OPTIMASS 7300 C. It was supplied in a compact version featuring a Titanium measuring tube (DN 25). The OPTIMASS 7300 boasts a single straight measuring tube and was thus able to be installed very compactly in a confined space. The general requirements for measuring systems for liquids other than water were taken into account. The measuring system's compact design meant that having no inlet run was a possibility. The OPTIMASS 7300 C meets all custody transfer requirements according to OIML R117 and MI-005. The high linearity of the mass flowmeter as well...

APPLICATION NOTE Food & Beverage Level measurement in starch production • Storing bran in 20 meter high silos • Permanent monitoring of bran stock for supply inventory • Low operating costs due to simplified and maintenance-free installation 1. Background The world’s production of starch and its by-products currently amounts to 6.5 million tons per year. Obtained mostly from corn, wheat and potatoes, starch is used as an additive in various industries: e.g. food processing, papermaking, clothing, chemical and pharmaceutical industry. Several processes allow for the production of starch: One of...
