To give you an idea of the value of the recovered powder, simply enter your data in the calculator below and see the estimated yearly gain from installing a Simatek bag filter.
What is your spray dryer powder capacity?
The powder output capacity of your spray dryer in kg per hour. This is the amount of dried powder your system produces, not the liquid feed rate.
What is the air capacity from your Spray Dryer?
The total volume of process air flowing from your spray dryer to the filtration system per hour. If you are unsure about the exact capacity,click the information icon
and use the diagram for guidance.
What is the temperature of the process air
from the spray dryer?
The exhaust air temperature leaving your spray dryer.
This is typically measured at the outlet before the cyclone or bag filter.
What is the estimated powder emission from a cyclone?
The powder concentration in the air leaving your cyclone(s), measured in milligrams per normal cubic meter (mg/Nm³). This value indicates how much powder passes through the cyclone instead of being recovered.
What is your desired powder emission
from a Simatek bag filter?
What is your production schedule?
Enter your typical production schedule. Consider planned maintenance, cleaning cycles (CIP), and seasonal variations.
What is the prime cost of the product?

Based on your input we have calculated the estimated value of powder recovery from the bag filter:
Basis for calculation
| Powder from the spray dryer | kg/h | 500 |
| Air capacity from spray dryer | kg/h | 25,000 |
| Temperature of process air | °C | 80 |
| Final Product price | per kg | 3.0 |
| Emission from Cyclone | mg/Nm³ | 250 |
| Corresponding to | % | 0.00 |
| Emission from Bag filter | mg/Nm³ | 5 |
| Corresponding to | % | 0.00 |
| Production hours per year | h/yr | 5,000 |

Estimated corresponding process air to powder capacity
Various factors is having an impact to the ratio between process air to the bag filter and final powder in the bag.
Following examples (but not limited to) can be mentioned:
- Whether the process air to the bag filter is from a single stage or multi stage spray dryer or from an agglomeration process, the ratio between process air and powder in the bag is fluctuating.
- The drying temperature, humidity of the drying air and exhaust air temperature to the bag filter.
- Total solids in the concentrate to the spray dryer versus the rest moisture in the final powder.
If the exact air capacity to the bag filter is not known the table shows an estimated range between the ratio between process air to the bag filter and powder in the bag.
