1. Introduction
The dairy industry demands automation equipment that can withstand the harshest hygienic conditions — including high-pressure washdowns, temperature fluctuations, and chemical cleaning.
A standard industrial PC often fails under these conditions due to water ingress, corrosion, and hygiene concerns.
The IP69K computer — specifically the 21.5-inch full stainless-steel Panel PC (UTC-W21XXG series) — provides a durable and sanitary solution for these challenges. Built for environments where cleanliness and reliability are critical, it is ideal for use in milk processing, cheese production, and packaging lines.
2. IP69K Protection and Hygienic Design
The UTC-W21XXG IP69K computer features a fully enclosed stainless steel chassis (SUS304) that complies with EHEDG and FDA hygiene standards.
Key features:
- IP69K protection rating: Withstands high-pressure (80–100 bar) and high-temperature (up to 80°C) water jets during CIP (Clean-in-Place) cleaning.
- Seamless, crevice-free enclosure: Prevents bacterial growth and makes the device easy to sanitize.
- Corrosion and chemical resistance: Ensures long-term reliability in dairy plant environments with acidic or alkaline cleaning agents.
This design guarantees that the IP69K computer remains operational even under frequent steam and water cleaning, making it a preferred choice for food and beverage automation systems.
3. Powerful Performance Options
The UTC-W21XXG IP69K Panel PC offers several processor configurations to meet different operational needs:
| Processor Option | Typical Application | Advantages |
|---|---|---|
| Intel® Celeron J1900 / J6412 | Basic HMI, SCADA terminals | Low power, fanless design |
| Intel® 10th Gen Core™ i3/i5/i7 | Process control, data visualization | High performance and fast response |
| Intel® 12th Gen Core™ | AI inspection, data analytics | Superior multitasking and graphics capability |
Interface configuration:
- 2 × USB ports (for barcode scanners, RFID readers)
- 2 × COM ports (for PLC, sensors, weighing instruments)
- 1 × LAN port (Ethernet connection to MES/SCADA systems)
Dimensions: 570 × 336.6 × 56 mm
Display: 21.5-inch full-flat capacitive touchscreen, glove-friendly operation.
4. Application Scenarios in Dairy Production
a. Raw Milk Reception and Testing
The IP69K computer connects to milk analyzers via RS-232 or Ethernet for real-time monitoring of temperature, fat content, and density. Data is automatically logged to MES or ERP systems for traceability.
b. Pasteurization and Processing Control
Operators can view process data, control heating/cooling curves, and monitor equipment performance in real-time. The robust IP69K-rated stainless steel housing ensures uninterrupted operation even during steam cleaning.
c. Filling and Packaging Automation
Mounted directly on the filling line, the IP69K Panel PC provides real-time control for filling levels, labeling, and sealing operations. Its hygienic design prevents contamination in open product zones.
d. CIP/SIP Cleaning Monitoring
The IP69K computer can withstand direct high-pressure cleaning, allowing it to be installed inside washdown zones. It monitors cleaning parameters such as pressure, temperature, and duration to ensure sanitation compliance.
e. Cold Storage and Logistics
Integrated with barcode or RFID systems, the device tracks product batches, monitors temperature, and ensures end-to-end cold chain traceability.
5. Software Compatibility and Connectivity
The IP69K computer supports multiple operating systems:
- Windows 10/11 IoT
- Linux Ubuntu
- Android (optional)
It also supports industrial software platforms such as Ignition, WinCC, and FactoryTalk, making it easy to integrate into existing automation networks.
Optional Wi-Fi, 4G, or 5G modules allow wireless communication for mobile or remote operations.
6. Benefits for Dairy Automation
- Hygienic and safe: Fully compliant with food-grade sanitation standards.
- Durable and reliable: Resistant to high-pressure water, detergents, and temperature fluctuations.
- Low maintenance: Reduces downtime and replacement costs caused by corrosion or moisture damage.
- Smart manufacturing: Enables data integration with MES/ERP systems for digital transformation in dairy plants.
7. Conclusion
The UTC-W21XXG 21.5-inch IP69K computer combines industrial durability, food-grade hygiene, and advanced computing performance.
Designed specifically for demanding environments like dairy production, it ensures reliable operation during continuous washdown processes and supports digitalized, traceable, and efficient manufacturing.
For dairy producers seeking to enhance automation while maintaining hygiene compliance, the IP69K computer is the ultimate solution.
