Solution for Drying Export-Quality Rice Crackers in Cu Chi: DeAir Installs 3 Daxwell Heat Pump Drying Rooms

Solution for Drying Export-Quality Rice Crackers in Cu Chi: DeAir Installs 3 Daxwell Heat Pump Drying Rooms

Scorched rice crackers (Cơm cháy) - a familiar snack for Vietnamese people - hold increasing potential to become a valuable export product. However, to bring this dish to the international market, traditional production methods like sun-drying or deep-frying reveal many limitations regarding food safety, inconsistent quality, and high production costs.

With the desire to professionalize their production process and deliver clean, crispy, and high-standard rice crackers to international consumers, a manufacturing facility in Cu Chi, Ho Chi Minh City, partnered with DeAir to build a modern and comprehensive drying solution.

Upgrading the Process, Aiming for Export Quality

The client's objective was to completely replace manual drying methods and establish a closed, tightly controlled process to ensure the following criteria:

• Product Quality: The rice crackers after drying must achieve the ideal crispy and porous texture, without being hard, scorched, and while maintaining an attractive golden color.
• Hygiene and Safety: The drying process in a sealed room must absolutely guarantee food safety standards, unaffected by dust, insects, or other environmental contaminants.
• Precise Drying Parameters:
  • Quantity: 03 drying rooms operating in sync.
  • Drying Temperature: Stably maintained at 40°C. This low temperature helps to dry the crackers slowly, creating a crispy and porous texture.
  • Room Humidity: Controlled at 40%RH.
  • Drying Time: A batch completed within 24 - 36 hours.

DeAir & The Comprehensive Daxwell Heat Pump Drying Solution

Based on the specific requirements of the rice cracker product and the client's export goals, the DeAir team advised the optimal solution: using the Daxwell heat pump dryer. DeAir not only supplied the equipment but also undertook the complete design and installation of 03 specialized drying rooms.

Why is the Daxwell Heat Pump Dryer the ideal choice?

1. Low-Temperature Drying Technology: The heat pump dryer by Daxwell operates extremely efficiently in the low-temperature range (40°C). The gentle flow of warm, dry air slowly removes moisture, causing the rice grains to puff up and create the characteristic crispy, porous structure without making the crackers hard or burnt.
2. Precise Humidity Control: The intelligent PLC controller of the Daxwell machine allows for stable maintenance of the humidity inside the drying room at 40%. This ensures a uniform drying process, guaranteeing that every rice cracker in the batch achieves the same quality.
3. Closed-Loop Process, Ensuring Hygiene: The entire industrial dehumidification system operates in a sealed room, completely preventing the intrusion of external elements and ensuring the final product is clean and safe.
4. Operating Cost Savings: The heat pump drying technology helps save up to 50% in energy consumption compared to traditional resistance heating, helping the client reduce production costs and increase the competitiveness of their export product.

The Result: "Made in Vietnam" Rice Crackers Ready to Go Global

With the 03 modern drying rooms installed by DeAir, the production facility in Cu Chi now boasts a professional, efficient, and stable manufacturing process. The finished rice crackers are not only delicious and crispy but also fully meet the strict quality and hygiene standards required for international markets.

The success of this project demonstrates how applying the right technology can help businesses in Vietnam's food industry enhance product value, compete confidently, and establish their brand on the global culinary map.
