Daxwell Rice Paper Dryer: The Technology Solution for Consistent Quality & Superior Productivity

Rice paper is a specialty, a part of Vietnamese culinary culture. However, traditional sun-drying methods are a major obstacle preventing producers from controlling their productivity and ensuring consistent quality, especially during the rainy season. This article will introduce a modern drying technology solution from DeAir that helps rice paper producers completely overcome these challenges.

1. The Challenges of Traditional Rice Paper Sun-Drying

• Unstable Productivity: Entirely dependent on the weather, making production impossible on rainy or overcast days.
• Unhygienic: Open-air drying cannot avoid dust and insects, affecting food safety standards.
• Inconsistent Quality: Harsh sun can make the rice paper brittle and easily breakable during packaging and transport. Weak sun leads to uneven drying and a high risk of mold.
• Costly in Labor and Space: Requires large drying areas and significant manual effort to monitor and turn the papers.

2. The "Golden" Technical Requirements for a Perfectly Dried Rice Paper

To achieve the highest quality finished product, the drying process must meet strict technical requirements:

• Low and Stable Temperature: To allow the paper to dry slowly, retaining its characteristic pliability without being "cooked" or blistering.
• Controlled Humidity: The air in the chamber must be dry enough to draw out moisture, but not so dry that it causes cracking.
• Even Air Circulation: To ensure that every single rice paper in the batch, regardless of its position, dries uniformly.

3. Heat Pump Drying Technology - The Answer for Vietnamese Rice Paper

Instead of using resistance heaters to heat the air to high temperatures, Heat Pump technology operates on a "cold drying" principle, creating a stream of dry, warm air (at a low temperature of 40-60°C). This offers superior advantages over other methods:

• Compared to Sun-Drying: 100% production control, absolutely hygienic.
• Compared to Resistance Heater Ovens: Drying at a lower temperature results in more pliable, less brittle rice paper. Furthermore, Heat Pump technology saves up to 70% in energy costs.

The result: Finished rice paper with ideal pliability, a clear appearance, and the delicious aroma of rice preserved.

4. The Daxwell Dryer: The Optimal Solution for Rice Paper Producers

DeAir's Daxwell smart Heat Pump dryer line is the solution designed to perfectly meet the above requirements:

• PLC/HMI Controller: Allows users to program unique drying cycles, ensuring consistent quality for every batch. This is a superior feature that standard ovens do not have.
• DeAir Quality: As a Made in Vietnam product manufactured under ISO 9001:2015 standards, it comes with full CO, CQ documentation. The machine uses high-end components like the Copeland compressor and an anti-corrosion evaporator coil, ensuring durable operation.

The effectiveness of the Daxwell dryer has been proven through real-world projects for rice paper producers in Binh Dinh, helping them to maintain production year-round, even during the rainy season.
