1. Humidity - The "Silent Enemy" of Vietnam's Food Industry
In Vietnam's tropical humid climate, high humidity is not just an inconvenience; it is a direct threat to food safety, product quality, and business profitability. Humidity control is no longer an option but a mandatory requirement for survival and growth.

4 major risks caused by high humidity in the food industry:
- Microbiological Hazards: Humidity is the ideal environment for mold and bacteria to thrive, causing product spoilage, degradation, and failure to meet critical food safety standards like HACCP and ISO 22000.
- Sensory Quality Degradation: Dry products such as milk powder, spices, and snacks become lumpy, lose their crispness, and turn stale. The shelf life of fresh products like vegetables, meat, and fish is significantly reduced.
- Condensation & Frost Formation: Causes dampness on workshop floors, ceilings, and walls, creating breeding grounds for bacteria and potentially dripping onto products, leading to contamination. In cold storage, moisture causes thick frost buildup, reducing cooling efficiency and wasting energy on defrost cycles.
- Reduced Production Efficiency: High humidity prolongs the time needed for drying and cooling products post-processing, and hinders the coating process for sugar or chocolate, making product surfaces sticky and unattractive.
2. DeAir's Specialized Humidity Control Solutions for Each Sub-Sector
Understanding the industry's unique challenges, DeAir provides tailor-made solutions for each application, based on experience and international standards.

2.1. Processing & Slaughtering Areas (Meat, Seafood)
Problem: Condensation on cold surfaces, especially stainless steel equipment, increasing the risk of cross-contamination.
DeAir Solution: Use of DeAir.RE industrial dehumidifiers with stainless steel casing or Olmas industrial models. The stainless steel casing ensures high hygiene standards, corrosion resistance, and ease of cleaning. The system helps maintain ideal humidity for processes like slicing bacon (recommended 45-50% RH).
2.2. Cold Storage, Coolers & Lobbies
Problem: Moist air infiltration whenever doors are opened, causing frost buildup on floors, cooling coils, and doorways, which is both hazardous and energy-wasting.
DeAir Solution: Install a Dezenno rotor dehumidifier in the lobby or airlock area. Rotor technology can handle humidity at extremely low levels (recommended 5-15% RH for cold storage lobbies), effectively "locking out" moisture from the outside and completely preventing frost formation.
2.3. Confectionery & Chocolate Production
Problem: Sugar or chocolate coatings become sticky, dry slowly, and lack a glossy finish. Hard candies absorb moisture and become sticky.
DeAir Solution: Use a DeAir.RE dehumidifier to create a dry environment, helping coatings set quickly and ensuring quality. For temperature-sensitive products, the DeAir.CRE isothermal dehumidifier is the optimal choice. The ideal environment for hard candy production is 25-30% RH.
2.4. Powder & Granule Products (Milk Powder, Coffee, Spices)
Problem: Products become lumpy, reducing quality, solubility, and causing blockages in automated packaging lines.
DeAir Solution: Strict humidity control in production, storage, and packaging areas. For instance, for products like instant coffee or cooling milk powder, maintaining humidity at 25-40% RH is crucial to ensure final product quality.
2.5. Drying of Agricultural Products, Foods & Seafood
Problem: Traditional heat-based drying methods are often energy-intensive, time-consuming, and can degrade product quality (color, flavor, nutrients).
DeAir Solution: The Daxwell Heat Pump Dryer and **DeAir.RE-H** are breakthrough solutions. This technology allows for drying at lower temperatures, preserving the product's quality while offering superior operational cost savings compared to electric heaters. Daxwell is widely used in processing agricultural products, food, and seafood.
