Accurate dosing with pneumatic vacuum transfer
Daxner’s innovative concept meets highest requirements for a modern ingredient handling facility - high throughput, utmost dosing accuracy, reduced dust generation and cross contaminations, easy cleaning and hygienic operation.
A high capacity vacuum transfer system pneumatically transfers all large components such as flour, sugar and dextrose from large outdoor silos directly to the receiver stations above the mixing lines. Not only does the pneumatic transfer system convey the material from A to B, it also serves as a dosing and weighing installation for batching all ingredients needed “just in time” on demand of the mixing line.
In explanation, a dosing system at the silo discharge precisely meters the batch quantity directly into the pneumatic suction intake unit and transfers the correct amount to the receiver bin station, which function we call a “vacuum scale”.
On the picture we can see high precision weighing hoppers or scales measuring the exact amount (+/- 50g) of minor ingredient from indoor silo stations containing starches, milk powders, sugars, flours etc. The same vacuum transfer system conveys the precisely metered batch from the weighing hopper to the receiver station at the mixing line.
Similarly the same vacuum transfer system collects big bag ingredients directly from the corresponding intake stations via rotary valves and pneumatically doses and conveys them into the vacuum weighing hopper at the mixing line.
In conclusion, this system combines both fully automated dosing and transfer of small, minor and major ingredients from silo and bulk bag intake location to the production lines at accuracies ranging from +/- 50g to +/- 2.000g depending on the ingredient batch component size – at a throughput rate of 10t/h of pneumatic vacuum transfer.
