1 IBC CONTAINER / DRUMS segregation free discharge
When butterfly valves are used in IBC bulk containers or drums, core flow often occurs in powder mixtures. Different grain sizes in shape and weight lead to segregation. The fine-grained and lighter powder in the middle of the funnel and above the butterfly valve empties first, followed by the coarser material at the funnel.
- Suitable PE double cone for all kind of drums or powder IBC
- segregation free transfer of mixed powder
- special drum hopper sizes DN400/457/500/600
- dimensions are customized and available for any container volume and size
2- Fill IBC containers with DT200 system without segregation
First, the IBC container is placed onto a lowered scissor lift table with turntable. The IBC is positioned below the DT200 with filling hose. The built-in, preset gravity lowering first causes the IBC to be lifted up to the filling hose, which is completely immersed through the manhole cover to the center of the hopper in the IBC when fully lifted. The fall distance of the medium from the end of the hose to the outlet of the IBC is thus minimized. It remains constant, as the IBC lowers uniformly with increasing filling and weight increase. This controlled lowering guarantees the mass flow and prevents segregation.
Properties:
- Anti segregation PE filling hose available for all shapes and dimensions of IBC containers
- Additional effect: gentle filling of fragile media such as tablets or capsules
- DT 200 Filling hose connection DN100-300 with central TC connection
- Easy assembly/disassembly of the PE filling hose
3- Segregation free filling downpipes with DT200:
Reasons:
The discharge of mixded solids with different characteristics into downpipes leads to the unpleasant property of segregation. The diversity of the powders mainly refers to the particle size, but includes all properties such as density and surface finish. The pharmaceutical industry is particularly affected by the problem of particle segregation. Leading to considerable quality reductions in the production of powdered remedies or in the mixture of tablet active ingredients.
Many factors can lead to segregation. According to Williams, one of the most common causes of segregation is the movement behavior of particles with different particle sizes and densities. Especially in free fall when fine particles and coarse particles trickle through downpipes.
Solution:
The DT 200 is particularly suitable for transporting powders in free fall without the risk of segregation. It prevents gravimetric separation (classifier effect) for products with different bulk weights and grain sizes. This results in increased cost-effectiveness when feeding tablet presses or packaging machines, for example, due to a significant reduction in the amount of rejects.This is achieved by a high-quality “inliner technology”, whereby no supply lines are integrated in the guide tube (in contact with the product). The system, which is designed according to GMP guidelines, is operated only with compressed air.Furthermore, an offset between the inlet, tablet press and ceiling bushing can be compensated for by tilting it up to almost 60°.
The hermetically sealed downpipe system made of stainless steel in NW 200 complies with GMP guidelines and is therefore easy to clean. When changing products, the insert is replaced. The system can also be retrofitted to existing systems and is available with installation lengths of 1 m to 6 m.
Function:
The medium is fed with a closed, internal hose inliner (top) by means of compressed air. When filled, the medium forms a plug in the hose in the inlet area. This moves downwards at a slow speed with increasing media pressure, so that no gravimetric segregation can take place. When the product transfer (bottom) is reached, the membrane opens and thus releases the cross-section to the product flow. To avoid contamination inside the downpipe, the surfaces in contact with the product are completely sealed in the tube. The constricted head is continuously moved by applying overpressure and vacuum, so that no external or separate connection cables are required.
