ESG Standard Mango Drying: Elevating Vietnamese Agricultural Products with Daxwell Technology & Solutions from DeAir

ESG - A New "Passport" for Vietnamese Dried Mangoes to Reach the World

In the context of globalization, the ESG (Environmental - Social - Governance) standard is no longer an option but has become a mandatory requirement for exported agricultural products. Especially with dried mangoes – the pride of Vietnamese agricultural products – applying green drying technology not only helps businesses overcome technical barriers but also creates long-term sustainable value. At leading companies like Nafoods Group or the clean agriculture model Vuon Ba Ba, the conversion from traditional drying ovens to Daxwell heat-pump dryers has created a major turning point in both product quality and environmental efficiency.

1. ESG Pillars in the Dried Mango Processing Industry

ESG in the agricultural industry is not just numbers on reports, but actual actions in the factory:

• Environmental: Reducing carbon footprint through the use of heat-pump technology. Daxwell dryers save up to 70% of electricity compared to conventional heat drying, and emit no greenhouse gases. Social: The closed-loop drying process ensures food safety and hygiene, protecting consumer health. At the same time, it enhances the value of fresh mangoes, helping farmers earn a more stable income. Governance: Using HMI screens and intelligent control systems to transparently display drying parameters, facilitating easy product traceability – a strict requirement of EU and US markets. 2. Case Study: Nafoods & Ba Ba Garden Conquers the International Market

  Nafoods Group: Pioneering Green Processing

  As a leading agricultural export group, Nafoods requires its processing procedures to meet stringent international standards. Recently, Nafoods successfully raised 160 billion VND in green capital from responsAbility to invest in upgrading processing capacity and supporting business models adapted to climate change. The application of energy-saving equipment such as the Daxwell heat-pump dryer is key to helping businesses maintain the natural golden color and soft, chewy texture without using many preservatives, while optimizing operating costs on a large industrial scale. Ba Ba Garden: A Sustainable Agricultural Model Ba Ba Garden focuses on the local elements and the "authenticity" of the product. Using cold drying/heat-pump technology helps to preserve the full content of vitamins and minerals in mangoes. Ba Ba Garden's dried mangoes are not only delicious but also tell a story about clean farming, perfectly meeting the "S" (Social) criterion in ESG.

  WHY CONVERT TO DAXWELL DRYER?

  Old Drying Oven (Resistance Electric)

  • Energy Consumption: 100%.
  • Color: Easily caramelized due to high heat.
  • Emissions: High (Large carbon footprint).
  • Uniformity: Low, requires constant manual tray turning.

  Daxwell Heat Pump Dryer

  • Energy Savings: ~70% energy savings compared to conventional dryers.
  • Color: Natural golden color, retains all vitamins.
  • Emissions: Closed system, no direct exhaust air.
  • Management: Automated via HMI screen.

  4. Standard Mango Drying Process with Daxwell Dryer

  According to scientific studies on processing technology, drying mangoes to ESG standards requires strict control steps:

  • Step 1: Pre-processing & Handling: Mangoes are washed, peeled, and sliced ​​evenly (about 10-15mm thick) to ensure uniform moisture removal.
  • Step 2: Temperature Setting: Maintain a low drying temperature of 45°C - 55°C. This is the optimal temperature range to prevent color change (caramelization) and nutrient loss.
  • Step 3: Multi-stage drying: Daxwell dryer automatically adjusts humidity from high to low, helping to draw water out from the core of the mango slices without hardening the surface.
  • Step 4: Control the moisture content of the finished product: The final product should have a moisture content of approximately 15-20%, which is ideal for mangoes to retain their softness, chewiness, and ease of long-term storage.

  

  5. Frequently Asked Questions About ESG Agricultural Drying Technology (FAQ)

  Does drying mangoes with a Daxwell machine really reduce costs?

  Absolutely possible. Although the initial investment cost is higher, the operating cost (electricity) is only about 1/3 compared to a conventional drying oven. A cost analysis shows that the business can quickly recoup its investment after 1.5 - 2 years thanks to the savings in electricity and labor.

  Does heat-pump dried mango require preservatives?

  Due to drying at low temperatures and in a sterile, sealed chamber to achieve the target moisture content (15-20%), microbial growth is inhibited. As a result, heat-pump dried mangoes have a very long natural shelf life without the overuse of chemical preservatives, meeting the "Clean Label" requirements of the ESG standard.
