Bigbag emptier feeds into the vacuum string via a cell lock. Alternatively, in many cases, if a more accurate dosage is desired, a shorter auger would be used.
The bigbag emptier is equipped with an EPDM (food approved) rubber top. Through this diaphragm the bigbag’s nozzle ends tightly, thereby avoiding dust generation in the room. Moreover, it is cheaper to produce than a stainless-steel plate.
The small component weight is placed at the far left of the platform and is used for fine dosing. This is a unique solution, developed by Tekfa and sold all over the world. In this sanitary solution it is equipped with special nylon bearings. Nylon does not rust and therefore there is no risk of contamination.
The tipping unit is designed so that cleaning can be done all the way around when cleaning on the inside. The disadvantage is of course, that the tipping unit thereby is dimensioned a little smaller than one would do under other circumstances.
The cyclones at the far right was also customized. Usually the filter is placed at the top of a cyclone. A regular filter rinse with air “knocks” the powder from the filter down into the bottom of the cyclone. With this customer, who produces baby food, there could be no risk of filter residue entering the material. Therefore, the filter is placed at the far left, from which there are discharge to a bigbag.
The facility has, of course, also got a control unit, which is not shown in the drawing. Tekfa provided both control and the last important component: software.
Tekfa’s software (or SCADA – Supervisory Control and Data Acquisition) is especially designed for handling and dosing of powder / granules. One of the key points of good dosage is that electronics and physics must integrate and support each other. And the procedures in those tasks are standard in Tekfa’s SCADA system, which we call TekfaVision.
