Increased competition brings needs for automation and quality control to the grain, milling and feed business
Plenty of companies within the grain, milling and feed industries have realized an increasing need for automation in production lines and reduction of production costs. Furthermore the business has realized a dramatic increase in raw material prices, with few or no signs of short term improvement.
With a weighing solution from Jesma in Denmark, the companies within the business can both automate their production processes, and at the same time supervise the production for improving the quality of the end product and reduce waste percentage.
Process weighing
“In-line” weighing is an effective way of avoiding over dosing of expensive additives, and adjusting the production to the actual need. Jesma is able to supply a wide range of dynamic and continuous scales and gravimetric dosing systems, and at the Danish grain processing and flour manufacturer Lantmännen Cerealia in Vejle such a gravimetric system has been installed.
The system consists of a flow scale type JesFlow in combination with a continuous “loss-in-weight” unit for dosing of an additive.
At Lantmännen Cerealia the Production Manager Mr. Torben Bodin explains: “In the past it has been difficult to find an accurate and reliable solution to measure the actual flow. It is our highest priority to know the actual product flow as we dose additives very accurate in relation to the main flow. At the same time the main flow is fluctuating, so the dosing of the additive has to follow the fluctuations very accurately. It is important for Lantmännen Cerealia that the product mix is as we expect and identical, we had to think of new ways to achieve the required end-quality.
Previously we have been using a combination of volumetric and gravimetric dosing technologies, however with the new system from Jesma, we both measure and dose additives gravimetric and we can establish an essential end-quality of our products. At Lantmännen Cerealia our position is clear – The process must be controlled as accurate as technology enables and the result of the Jesma solution has been an absolute success” ends Torben Bodin.

The regulation of the additive dosing through a “loss-in-weight” system reacts quickly and effectively due to the “Master-Slave” regulation based on the main flow.
Managing Director of Jesma Mr. Palle Serup explains: “At Jesma we have extensive experience within continuous weighing and gravimetric dosing of any bulk material. Based on our experience we find it easy to enter a dialogue with our customer at an early stage to find the best suitable and technical optimum solution for the project. Jesma not only delivers standard units, but also develops a lot of customer- and project adapted weighing solutions. It is highly surprising how much the raw material consumption can be reduced only be choosing the correct weighing solution.

”Loss-in-weight” unit
A ”loss-in-weight” unit from Jesma can be used anywhere where continuous dosing of powder or another bulk material needs to be dosed with high accuracy and reliability.
Regulation of the mixture by using weighing systems results in a more accurate mix compared to other available techniques. This results in a more uniform end-product, and thus higher end-quality. Jesma “loss-in-weight” units are designed according to the specific requirements of the customer, and are available with capacities from few kg to several tons per hour. All units are designed and constructed according to the actual product and thus secures a high operational safety and optimum user friendliness.
During operation of the “loss-in-weight” unit the bin is slowly emptied, and the loss in weight in relation to the time results in the mass signal which controls the dosing to the required value. Jesma´s own developed control system continuously updates the ratio between the required amount and the actual dosing. When the bin is nearly empty and it is re-filled the control system uses the historic values as basis for the relation between actual dosing and the weight loss in the bin. When the bin is full the control system switches back to normal operation. This type of control, without “freezing” the operation during filling of the bin, results in a unique dynamic accuracy and a very accurate regulation of the product flow.

Dynamic and development
From Jesma Mr. Palle Serup explains: “Jesma is a very dynamic company, which constantly aim at developing new products and concepts which helps our customers achieve their goals. We are a very innovative company where quality and flexibility are corner stones in our development. We aim our products at a quality that reflects the rest of our company, which means total quality control and tested equipment. For that reason we are confident that our equipment lives up to the high standards of our customers when it leaves our factory.”
