Dehumidifier Machine
- Dehumidifiers are used in the powder industry to control moisture and prevent issues like caking, sticking, and clumping: Spray drying
Dry conditions are ideal for spray drying, so dehumidifiers are used in this process
- Handling and storage
Dehumidifiers are used to create dry conditions for handling and storing hygroscopic powders.
- Powdery food processing
Moisture in the air can cause powdered foods to stick together, which can interfere with processing and affect the final product.
- Pharmaceutical manufacturing
Dehumidifiers are used to prevent hygroscopic materials from sticking to belts or presses or blocking conveying paths.
- Effervescent tablets
Excess moisture can cause tablets to stick to machines and affect their surface finish.
Cough drop syrups
High humidity can cause the material to stick to the stamping machine.
Dehumidification for Powder Processing and Spray Drying
Dry conditions are the optimal climate for spray drying, handling and storage. However indoor climate conditions fluctuate and seasons change. If you want to optimise production, lower operating costs and reduce your energy consumption, consider dehumidification technology.
Desiccant Dehumidification systems are the best option for dairy product processing because they are superior at moving sticky, lightweight and hygroscopic powders.
Dairy and Powder – Humidity Control
Common Industry Problems
- Quality is affected due to high moisture levels
- Extra manpower required to combat fluctuating humidity
- Loss of production in higher humidity months
- Operators have to constantly re-adjust settings because of humidity changes
- Very hygroscopic powders can be difficult to produce
How to Keep Powder From Clumping
Dealing with changing weather conditions including humidity creates challenges in providing consistent quality when spray drying.
Desiccant Dehumidifiers Create Dry Air for Powdered Products
The best way to overcome these challenges is to use a desiccant dehumidifier for drying a liquid product.
Dehumidification physically removes the moisture from the incoming air. The dry air is in direct contact with the product during the process – so it is no longer affected by the weather.
Furthermore, the same dehumidified air used for conveying can be delivered into the silo or hopper and will not cause the ingredients inside to solidify.
pneumatic conveying system
Humiscope dehumidifiers can include a pneumatic conveying system which can move dry materials in bulk better than conventional mechanical systems and at a lower cost.
Pre-drying the air using a dehumidification system allows for stable inlet conditions, enabling consistent quality and increased performance in the spray drying process.
