Processing a flush
Processing a flush mounted system like the Baumer Hygienic Connector enables to measure quick, as there is no thermowell required. This makes the sensor faster. The flush mounted integration speeds up phase shift operations as well in production as while cleaning. This leads to saving product, time and energy. Hygienic design is a basic requirement for efficient and safe Food and Beverages processes in general. Using flush mounted sensors will improve every days performance. Local networks MTP The control system of the future might be even faster, using a local digital network as we can see in Modular Type Package set up. The valve and the sensor can communicate in a local network, very fast, very efficient. From the control system only the generic program is supplied, all other control duties are handled locally. Quick temperature sensor will speed up the process even more using a IO Link protocol. Fast signals, without losses and fast communication time allow speeding up the loop even more. Baumer IO-Link sensors support as well the future upgrading of systems. Dual Channel technology will enable to run the system today with 4 … 20 mA, using IO-Link only for parameterization and predictive maintenance, while in future the IO-Link signal will be the main signal as well for the signal transfer after the system is digitalized. Cleaning regime As standard effect, any build up or fouling will influence the transfer capacity of a heat exchanger. This can sometimes be mineral based layer on the media side, but usually it is more the fouling of product burned onto the surface. The colder a process can be kept, the longer it takes to build up a layer that requires a cleaning to get back to efficiency. But as build up can`t be prevented completely the main topic is to identify the best possible time to stop production and start with a CIP step. Especially the plate heat exchanger operation can make a huge step forward by not wasting production time because of early cleaning, but also not wasting energy because of too late cleaning. The pressure sensor PBMH from Baumer is a perfect match for this application. High sensitivity, digital communication and a strong performance in changing and especially hot temperatures, support the detection of the pressure difference rising between inlet and outlet with the time. In that way, the best possible timing to start the CIP can be measured and as well predicted. With a sensor in the media side or on the unsafe product side, it can be as well ensured, that the pressure on the treated side is always higher, avoiding that unsafe product reaches it. Detecting leakages that introduce product in to heating or cooling water could be recognized very fast, using the conductivity sensor CombiLyz AFI. Energy Monitoring On the other side, it also possible to measure the required heat that is supplied to the exchanger and compare the development with the product flow. The calorimetric flow sensor FlexFlow PF20H can measure the hot water supply and the supplied amount of energy can be compared with the produced product. Summary: Based on hygienic design, we have a lot of opportunities to improve the product quality, lower the energy usage, bring up the OEE and keep Food Safety ensured in heat exchanger operations. Quick temperature measurement, high accurate and temperature unaffected pressure measurement and the smart use of different flow meter will lead to best possible results. The mix of Baumer products designed for this process environment help to stay competitive improving daily operations. Let us help, finding the best suitable solution for your application. fmt The faster temperature measurement compresses and accelerates the control loop 32 food Marketing & Technology • October 2021
Processing Online Moisture Measurement on Cereal, Grains & Powders For food products produced by the grain industries, moisture is a crucial issue throughout the manufacturing process. Too little or too much moisture at different stages of production can affect the quality of the final product and the optimisation of production costs. By using microwave technology, it is possible to monitor moisture online, allowing trend analysis and early intervention when necessary. The Berthold moisture systems can measure grain moisture when harvested, throughout processing, and before storage and sale. This significantly reduces production costs and improves product quality. For example, as a rule the moisture content of couscous must not exceed 13.5%. Early recognition of fluctuations The MicroPolar system provides real-time, continuous measurement of moisture or dry matter content in a wide range of products. The measurement is performed directly on the main stream. This microwave measurement is nonintrusive; no sensor comes into contact with the product to be measured, which reduces maintenance. The measurement is not influenced by the color, viscosity or inhomogeneity of the product. Moreover, the measurement is carried out on the entire product. The MicroPolar system is easy to install. The processing unit has a large display and a user-friendly interface. Calibration can also be performed on site. Measuring principle and function The installation possibilities are manifold, common installation situations are e.g. on pipes, belt conveyor, shafts / chutes. Possible applications are on all types of cereals, grains and powder products including maize, semolina and couscous, as well as soya, rice, coffee, starch, nuts, rice, etc. The microwaves pass through the product to be measured, causing the free water molecules, which have excellent dielectric properties, to rotate. This rotation causes a slowing down (phase shift) and a decrease in amplitude (attenuation) of the microwaves, resulting in a very accurate measurement of the water content. Thanks to the multifrequency technique used by Berthold, measurements are highly reliable and stable and are not affected by reflectance or resonance.
