In March 2026, Changzhou Changhai Drying Equipment Co., Ltd. successfully completed production, assembly, air tightness testing, low-temperature debugging and delivery of three sets of square vacuum dryers. The equipment was shipped in bulk to Thailand and delivered to a local food processing enterprise, specially used for low-temperature dehydration and fine drying of fruit and vegetable powder.

Fruit and vegetable powder is a typical heat-sensitive food material, rich in vitamins, anthocyanins, dietary fiber and other active nutrients. Traditional high-temperature drying easily causes nutrient loss, oxidation and discoloration, powder agglomeration and flavor volatilization, which greatly affects the final product quality. The Thai customer focuses on deep processing of tropical fruit and vegetable powder with strict requirements on color retention, active ingredient retention and uniform moisture content, which cannot be met by ordinary hot-air drying equipment.

Tailored for heat-sensitive food materials, our square vacuum dryer adopts low-temperature vacuum negative pressure drying technology. Working in a fully sealed vacuum environment, the equipment lowers the boiling point of water significantly and realizes drying at a low temperature of 40℃–60℃. The whole process avoids high-temperature oxidation and dust pollution, maximizing the retention of natural color, flavor and active nutrients of fruits and vegetables, and solving common industry problems such as discoloration, deterioration and nutrient loss.

The equipment is fully made of food-grade stainless steel with a smooth, dead-angle-free inner tank, which is easy to clean and disinfect and fully meets Southeast Asian food hygiene standards. With uniform internal temperature distribution, it ensures consistent drying effect and fine, loose finished powder with stable moisture content. The vacuum degree and drying time can be adjusted flexibly to adapt to various materials such as mango powder, durian powder, spinach powder and carrot powder.

The bulk delivery of three units fully reflects the Thai customer’s high recognition of Changhai’s equipment quality, food-grade drying technology and comprehensive service capability. With reliable performance and mature low-temperature vacuum drying technology, our food drying equipment continues to expand the Southeast Asian market, helping overseas food enterprises achieve high-quality, standardized and green deep processing production.

In the future, Changzhou Changhai Drying will continuously upgrade professional food drying equipment, further explore the Southeast Asian market, and provide energy-saving, clean, efficient and high-quality complete drying solutions for the global food processing industry.
