Eliminating Odor in Seafood Drying with Daxwell Closed-Loop Dryers

Eliminating Odor in Seafood Drying with Daxwell Closed-Loop Dryers

In the dried seafood processing industry (seasoned fish, squid, dried shrimp), the hardest puzzle is not the drying technique itself, but odor control. Emitting a pungent fishy smell into residential areas not only affects the community but also poses a massive legal risk to the business. Daxwell's closed-loop drying technology is the "key" helping factories operate sustainably and meet today's strictest environmental standards.

1. Alarm Over Odor Pollution in Seafood Processing Plants

Odor pollution from seafood processing plants, especially fish drying and fishmeal facilities, is becoming a pressing issue in many localities. According to reports from reputable press agencies:

• Tuoi Tre Newspaper reported on residents' intense frustration when factories emit pungent odors, severely affecting their daily lives.
• Da Nang Newspaper and Agriculture & Environment news sites continuously report on factories being inspected, fined, and ordered to suspend operations due to their failure to control fishy exhaust emissions.

If the technology is not upgraded, businesses will not only lose their reputation but also face the risk of permanent closure.

2. Why Are Traditional Drying Kilns the "Culprit" Behind Odors?

Traditional thermal drying kilns operate on an "Open-loop" principle. The machine draws in fresh air, heats it up, and blows it across the surface of the seafood. After absorbing moisture and odor-causing molecules (from protein and spices), this air stream is exhausted straight into the sky.

The foul odor travels far with the exhaust, especially during the rainy season or on calm days. The fishy smell lingers around residential areas, creating severe stagnation and pollution. This is the fatal flaw of outdated drying technologies.

3. Daxwell Dryers: Closed-Loop Technology - Zero Odor Emissions

The Daxwell Heat-pump Dryer completely changes the game with its "Closed-loop" technology. The drying air is 100% continuously circulated inside the drying chamber and the machine, without any exhaust vents leading to the outside environment.

At the Daxwell machine's cold coil, the moisture containing the fishy smell is condensed into liquid water. This water is piped directly into the factory's centralized wastewater treatment system. As a result, no foul odor is released into the air, allowing the factory to operate smoothly even in the middle of a residential area.

4. Dual Benefits: Achieving ESG Standards and Optimizing Profits

Investing in Daxwell closed-loop dryers is a strategic step helping businesses achieve ESG (Environmental, Social, and Governance) standards - the "ticket" to entering international supply chains:

• Environmental (E): Zero exhaust emissions, no odor pollution, reduces electricity consumption by 70%.
• Social (S): Builds good relationships with the surrounding community, avoiding public outrage and disputes.
• Food Quality: Low-temperature drying (usually under 60°C) helps seafood retain its natural color, perfect chewiness, and nutritional content without being overcooked.

5. Practical Applications: From Seafood to Regional Specialties

Daxwell's technology is not limited to seafood. The system's flexibility allows customization for various factory types:

For instance, in the rice paper drying project in Binh Dinh, applying Daxwell dryers helped the facility maintain continuous production throughout the rainy season, ensuring absolute hygiene without affecting the surrounding environment.
