Dinnissen introduces Smart Discharge for direct infeed from big bags
Dinnissen is introducing Smart Discharge, a new system which makes it possible to feed ingredients into a processing line directly from the big bag.
The new system also offers advantages to companies looking for greater flexibility or for a cost-efficient solution to a shortage of silos or premix storage units.
Many companies in the animal feed industry needs to feed micro ingredients, premixes and other ingredients from a holding location into processing lines do so only from silos.
Although this is a classic solution, it's not always a practical one for storing and handling smaller quantities or ingredients that are sensitive to contamination. Manufacturers of animal feeds are using an increasing variety of (macro or micro) ingredients and premixes stored at an appropriate location in order to produce an even greater variety of high-quality or tailor-made products. In particular when ingredients are involved that are used in relatively small quantities (300 g/h to 8000 k/h), a classic storage solution using silos or premix storage units has many disadvantages.
Dinnissen's new infeed system feeds ingredients for compound feed, fish feed and pet food production directly into the system from the big bag. To do so, the big bags are fed into a big bag emptying station and automatically connected to a dosage/weighing station and a pneumatic Slow-Flow transport system from Dinnissen. After the ingredients have been automatically dosed or weighed out, they are fed into the mixer via a vacuum-assisted or blower type transport. To accomplish this, the Slow-Flow transport system uses low air speeds and a relatively high loading factor, making it very energy-efficient.
As a result, Slow Flow Conveying is very suitable for hygienically, carefully and efficiently transporting bulk solids that are fragile, sticky or sensitive to wear and tear. Feeding the ingredients in directly from the big bag prevents contamination and build-up of residual materials in transport lines and cells.
The new system offers cost savings and flexibility to producers using many different expensive micro-ingredients, premixes and other products held in interim storage units. As the direct infeed system also prevents the build-up of residual products and contamination in transport lines, the end product quality is also better.
Finally, such a system is also very cost-efficient. Users also have the option of feeding ingredients into the system directly from 25 kg bags. The bags are then first placed in a Dima bag discharge station supplied by Dinnissen Process Technology, based in Sevenum. The maximum infeed capacity for feeding ingredients directly from big bags or bags vary somewhat, but lies between 10 and 20 tonnes per hour.
