Learn how precise humidity control and desiccant dehumidifiers solve common challenges in marshmallow production—reducing spoilage, sticking, and downtime. Explore proven air quality solutions for confectionery plants in Canada and the USA.
Optimal Humidity Control for Marshmallow Production
Consistent air quality is vital for food industry manufacturers, especially in marshmallow and confectionery plants. Humidity fluctuations lead to product defects, packaging issues, and frequent equipment failures.
- How can you prevent condensation and product spoilage in confectionery areas?
- What’s the key to extending marshmallow shelf life and reducing downtime?
- How do you maintain a reliable microclimate for every step – from conditioning to storage?
To achieve these goals, you need precise humidity control at every production stage.
Risks of Uncontrolled Humidity in Marshmallow Plants
- Condensed moisture on equipment and facility surfaces
- Packaging film sticking to product
- Mildew and bacteria growth in storage and process areas
- Clumping and sticking of hygroscopic ingredients (sugar, agar, pectin, cocoa)
- Production line stoppages and idle equipment
- Failures of electronics and control systems
- Premature deterioration of building structures
The most effective solution is installing an industrial desiccant dehumidifier to remove excess moisture from both air and production spaces.
Critical Stages for Humidity Control
- Conditioning and Drying: Ensures high-quality finish and texture.
- Glazing: Prevents stickiness and film adhesion.
- Pre-packing: Stops clumping of products and ingredients.
- Storage: Maintains product integrity and shelf life.
Desiccant dehumidifiers provide consistent results in these zones, proven in real-world case studies and food processing environments.
Production & Storage: Recommended Climate
| Stage | Relative Humidity (RH %) | Temperature (°C) |
|---|---|---|
| Glazing/Drying | up to 75 | up to 18 |
| Cooling (with rollers) | up to 40 | 10 |
| Conditioning/Drying | up to 60 | 35 |
| Prepacking/Packaging | 30–40 | 21–24 |
| Ingredient Storage | 45–55 | 20–22 |
| Finished Product Storage | 70–75 | 18 |
Benefits of Desiccant Dehumidification
- Reduces production waste
- Prevents products from sticking to conveyor lines
- Eliminates condensation and mildew
- Minimizes equipment downtime and emergency stops
- Creates stable microclimate in both production and dry room storage
- Saves energy with efficient moisture removal
- Easy installation, compact size, and low maintenance
- Corrosion-resistant, food-safe design (stainless steel, aluminum zinc)
- Full compliance with quality standards in Canada, USA, and EU
How Does a Desiccant Dehumidifier Work?
Process air passes through a special silica gel rotor that captures water molecules. A separate air stream, preheated to 90-140 °C, regenerates the rotor and expels moisture as warm, humid air.
