A common example of application in the chemical sector is the batch feeder. The need is dispensing individually different ingredients, including liquids, into a weighed hopper to make them available to the following process, for example a mixing cycle.
The most diverse devices can be used to store, extract, transport, weigh and mix the products of our recipe. The distinctive feature of a batch plant is always the high accuracy required, the system of static weighing is suitable for reaching weights as accurate as smaller than 0.1%. When the number of ingredients to be managed is high, we use a PLC system. This solution allows for total control of the plant, from the levels of all the ingredients, to the management of the recipes with direct control of all the dosing units (valves, screws, rotating valves, etc.), the registration of all the plant alarms and the production data by shift/lot/order for purposes of tracking the product. Often the application in the chemical feld leads to the need for the plant to be certified as in ATEX release.
