DIT Dosing System

Unloading bulk solid material can be a troublesome and risky operation if not managed correctly. The DIT® iris dosing equipment can help manage this delicate phase of unloading into continuous liner drums. In fact, controlling product flows, such as highly active powders, is not only a safety need for the operator but utlimately a matter of product quality.

During the unloading phase from a dryer, for instance, dosing operations are performed by a rotary valve that allows regulating flows uniformly. However, it also requires constant cleaning and hence several maintenance operations. The external positioning of the iris dosing equipment guarantees cleanliness and ease of use of powder flow.

The iris acts as a dispenser due to its manual opening and closing mechanism, allowing regulation of the quantity weighed by the scale under the drum. The scale can be connected to a display mounted on the structure, enabling operators to work more precisely as material is unloaded into the continuous liner. Once the desired dose is reached, the separation operation can easily be accomplished using CSV Containment’s Twin Tie® kit.

The diameter of the dispensing iris is customizable, and the canister onto which the liners are mounted has an inflatable gasket.

This type of dosing system consists of:

• an adapted flange, with hopper, to connect the equipment from which to unload
• corrugated canister with an inflatable bag-tightening gasket
• folded or donut-shaped liners
• DN450 iris with a steel body and conductive EPDM diaphragm
• floor scale placed on a cart equipped with wheels
• weight control display mounted on the structure of the iris dosing
• ATEX configuration
