Project Background & Customer Challenges
As the dairy market in Vietnam and broader Southeast Asia experiences explosive growth, consumer demand for high-quality infant formulas and functional adult milk powders has reached unprecedented heights. To capture this booming market, a leading local Vietnamese dairy processor sought to transition from low-capacity, semi-automated operations to a world-class, fully automated milk powder manufacturing plant.
The client approached Weishu Intelligent Machinery with several critical engineering challenges:
-
Stringent Hygiene Standards: The entire system had to strictly comply with international GMP and HACCP regulations to seamlessly pass the Vietnamese Ministry of Health’s audits.
-
Thermal Sensitivity: Milk is highly heat-sensitive. Traditional drying methods often result in the loss of vital nutrients or the formation of burnt particles.
-
Process Consistency: Manual ingredient dosing in their old facility caused batch-to-batch quality fluctuations, which is unacceptable for premium nutritional products.
Project Scale at a Glance:
-
Raw Material: Fresh milk reception of 150 tons per day (T/D).
-
Final Product: Premium nutritional milk powder and infant formula.
-
Delivery Scope: Turnkey EPC solution delivered by Weishu Intelligent Machinery (Process design, equipment manufacturing, international logistics, installation, and commissioning).
Advanced Technical Solutions & Core Equipment
To address these challenges, the engineering team at Weishu designed a highly customized, fully automated processing line featuring three core technological highlights:
Multi-Stage Spray Drying System with Integrated Fluidized Beds
To protect the nutritional integrity of the milk, Weishu deployed its advanced low-temperature, low-pressure multi-stage spray drying tower.
-
Nutrient Retention: By precisely controlling the air temperature and residence time, the system minimizes thermal damage, preserving active nutrients such as immunoglobulins and lactoferrin.
-
Perfect Instant Solubility: Integrated internal and external fluidized beds allow for precise secondary drying and agglomeration (granulation). This ensures the final powder achieves optimal particle size distribution and a moisture content below 4%, resulting in excellent instant solubility without clumping.
High-Precision Automatic Micro-Dosing System
For critical micro-ingredients such as vitamins, minerals, and DHA, manual dosing was completely replaced by Weishu’s closed-loop automatic dosing system.
-
Utilizing high-precision weighing modules, the system achieves a dosing accuracy of ±0.1%.
-
The entire process operates under a fully enclosed pneumatic conveying environment, eliminating any risk of cross-contamination.
Energy-Saving MVR Falling Film Evaporator
Before entering the spray dryer, raw milk must be concentrated. Weishu integrated a Mechanical Vapor Recompression (MVR) falling film evaporator. By recycling the latent heat of secondary steam, this system reduces steam consumption by over 60% compared to traditional multi-effect evaporators, dramatically lowering the factory's operational carbon footprint.
Cross-Border Execution & Localized Commissioning
Delivering a heavy-duty industrial project overseas requires seamless coordination. Weishu’s global execution strategy ensured a hassle-free turnkey experience for the client:
-
Global Standards Compliance: Every component in contact with the product was fabricated by Weishu using certified SUS316L hygienic stainless steel. Prior to shipping, the entire line underwent strict Factory Acceptance Testing (FAT) at our headquarters.
-
Streamlined Cross-Border Logistics: Dozens of oversized equipment containers were securely dispatched and cleared customs smoothly under our dedicated logistics management.
-
On-Site Expert Deployment: A veteran team of Weishu mechanical, electrical, and automation engineers was dispatched to the site in Vietnam. Working closely with local teams, they overcame language barriers and completed the mechanical installation, pipeline integration, and software loop-testing ahead of schedule.
-
Knowledge Transfer: We conducted extensive, localized Standard Operating Procedure (SOP) training for Vietnamese operators, covering system operations, preventative maintenance, and automated CIP (Clean-in-Place) protocols.
Quantifiable Business Outcomes
The commissioning of the 150 T/D milk powder production line has yielded remarkable economic and operational benefits for our client:
-
100% Quality Pass Rate: The finished milk powder successfully passed all physical, chemical, and microbiological tests, securing top-tier food safety certifications in Vietnam on the first attempt.
-
40% Labor Reduction: High-level automation from raw milk reception to final nitrogen-flushed packaging allowed the client to optimize their workforce, reducing production line staff by 40%.
-
25% Energy Savings: Thanks to Weishu’s MVR technology and smart heat recovery loops, the plant's overall energy consumption dropped by 25%, giving the client a massive cost advantage in the market.
-
Rapid Market Expansion: With reliable, large-scale production secured, the client successfully doubled their supply chain response speed, rapidly capturing premium market shares across Vietnam and neighbouring countries.
