Customer requirements.

One of the world’s leading research based pharmaceutical and healthcare companies, and one of the oldest pharmaceuticals companies in India, required a conveying solution for handling the raw material from the raw material warehouse to the process silos, then weighing and batching of the raw material for further conveying to the processing vessel and then finally conveying the finished product.

What is critical?

The hygiene aspect was one of the most critical parameter in designing the system, considering handling of hygroscopic material.

Solution.

Raw Material Handling to Milk Standardization area

Milk standardization process requires a system to standardize the quality of Milk before it is used in the process. Desired quantity of Skimmed milk powder and weigh powder are dissolved in an Agitator Vessel. Milk additive powders are always critical to handle due to their hygroscopic nature and hygienic aspect being extremely critical when designing such a system.

We designed a Lean Phase Pneumatic conveying system for handling skimmed milk powder and weigh powder from raw material ware house to process silo in process building and milk standardization area. Air from the atmosphere was filtered and dehumidified using the suitable type of dehumidifier and used for conveying, for nullify the hygroscopic nature of the milk additive powders and preparing for easy conveying.

Skimmed milk powder and weigh powders are available in 25kg/50kg bags. These bags are to be unloaded into bag dumping station with the bin mounted dust collectors to ensure the dust free unloading of bags in to the hoppers. Then powders from the hoppers would be fed to the conveying line with the help of specially designed rotary air lock valves and conveyed to the batching hoppers.

Weighing - Batching system.

In weighing and batching system, skimmed milk powder and weigh powder are to be received in weigh hopper and batch is prepared. Weigh hopper was provided with precise load cells which accurately weighs the required quantity of milk additive powders and gives the feedback to panel. And the batch is ready to be conveyed to Milk standardization area.

Milk Standardization system.

Measured quantity of skimmed milk powder and weigh powders to be fed to the Milk Standardization Vessel for dissolving the skimmed milk powder and weigh powder in chilled Milk at 4 Deg C temperature. The dissolving operation of skimmed milk and weigh powder is carried out with the help of agitator vessel.

After dissolving measured quantity of skimmed milk powder in the Milk Standardization, the Standardized Milk will be fed back with the help of Milk Pump. The whole operation sequence is operated through the PLC control in AUTO as well as manual model.

Our competence to create a complete solution rendered high quality and reliable results.

Precision matters
Industry: Iron & Steel

Customer requirements.

One of our esteemed customer required accurately weighed raw material feeding to discharge hoppers above the weigh hopper. Then weighing and conveying the complete batch to the destination hopper from which it is fed to the further process.

What is critical?

Weighing accuracy being most important, the designing of the conveying and weighing system had to be done with extreme precision.

Solution

We successfully installed and commissioned a batching and formulation system in steel plant additives section in our customer’s steel plant.

1. Bag Slitting Machine & Raw Material Handling

  • In this part of the system various powders, a part of the batch are feed to the conveying system, achieved with help of bag slitting machines and jumbo bag unloading stations.
  • The fully automatic bag slitting machines were installed to transfer the small bags (25kg/50kg) from stacking area to bag slitting cutter and then unload the powders in to hopper and remove the residue of bag material. Similarly the jumbo bag unloading stations with the electric hoist arrangement were provided for unloading the powder from jumbo bag to the collecting hopper.
  • To carry out the complete unloading operation in a dust free manner we provided the proper venting arrangement and bag filter. Then the collected powders are conveyed to each destination hopper above the weighing hoppers with the help of dense phase conveying system.
  • Dense phase systems were opted to convey the raw material due to abrasive nature of the powder. In dense phase system, by keeping the low air volumes with high pressure we limit the end conveying velocities. Which in turns safe guards the system components form wear and tear due to abrasive nature of the materials.
  • Material is conveyed in closed piping with diverter arrangement to divert the conveying flow in to selected destination hopper. Bin mounted bags filters were provided above the destination hoppers to separate the conveying air from powders.

2. Weighing - Batching system

  • Material from various destination powder hoppers is received in weigh hopper and the batch is prepared with the necessary proportion of each powder.
  • Weigh hopper is provided with precise load cells which weigh the material and gives the feed to panel. The batch is ready to convey for further processing.

3. Air slide conveying system and pneumatic conveying system

  • The completely prepared batch can be unloaded to the next conveying hopper with the help of air slide (Air-lift) arrangement.
  • The completely prepared batch can be unloaded to the next conveying hopper with the help of air slide (Air-lift) arrangement.

The whole operation sequence is operated through the PLC control panel in AUTO as well as manual mode.
Our competence to create a complete solution enables high quality and reliable results.
