From Hau Giang to the Nation: The Success Story of Soursop Tea and the Daxwell Drying Solution

1. The "Soursop Tea Craze" of 2023: When a Market Opportunity Knocks

In 2023, the Vietnamese beverage market witnessed the explosion of a 'new star' called soursop tea. According to media reports, this drink quickly created a "nationwide craze". A huge business opportunity opened up almost overnight. But for producers in the "soursop capital" like Hau Giang province, the question was: How to seize this opportunity and supply the market with a premium quality product?

The biggest barrier was not the supply of raw materials, but the drying technology – the crucial stage that determines the flavor, color, and nutritional value of the finished tea slices.

2. The Technical Challenge: Preserving the "Soul" of the Soursop Fruit

Drying soursop tea is not just about removing water. It is a complex technical problem that requires precise control to preserve the "soul" of the fruit.

• Flavor & Nutritional Requirements: It is essential to retain the tangy flavor and delicate aroma, while preserving the maximum amount of vitamins and heat-sensitive antioxidants.
• Visual Requirements: The dried tea slices must have a natural bright white color, without turning yellow or dark due to high temperatures.

3. [CASE STUDY] DeAir Partners with a Hau Giang Business to Seize the Opportunity

In February 2023, a production facility in Hau Giang partnered with DeAir to build a professional drying solution to capture the opportunity from the "soursop tea craze." The implemented solution was a cold drying room using the Maxwell-300S Heat Pump Dryer (the predecessor model of the current Daxwell S-Series).

Why the Daxwell S-Series?

• State-of-the-art Cold Drying Technology: The low-temperature range (25-80°C) of the S-series is the "golden key" to gently drying soursop, fully preserving its flavor and nutrients.
• Closed-Loop Drying Cycle: Maximally retains the product's aroma, preventing it from escaping into the environment, resulting in a richer final tea product.
• Uniform Quality: The intelligent controller ensures that every slice in a batch achieves perfect dryness and quality, ready for packaging.

4. The Result: From a Local Agricultural Product to a Nationwide "Hot Trend"

By investing in the right technology, the client was able to confidently produce a high-quality product and fully capture the market opportunity.
