Flow scale and LIW system
– Newly developed flow scale for the process industry….
At Lantmännen in Denmark, they wished to measure the flow of their flour production and at the same time add a substance in relation to the flow amount. They wished an online picture of the production flow, so that they could accurately add a substance in accordance with the flow.
Jesma decided that Jesflow would be the perfect solution for the measuring of the flour flow, and that the loss-in-weight system VDI could subsequently ensure the addition of substances. The two weighing systems are functioning together in a master-slave relation, where the material flow is the master and the substance is the slave.
The new system secures that the mixing ratio between the products is the same at all times. When Lantmännen sieves and re-circulates the flour through 3-4 different sieves, the material flow may vary from 95% to 105% of the ideal capacity. This is exactly the process which the new weighing system optimizes and quality secures.
