Touch-Screen Controlled Continuous Distillation Unit

The XINYU HUACHUANG Touch-Screen Controlled Continuous Distillation Unit is an advanced, industrial-grade separation system designed to simplify complex continuous purification processes. Engineered for maximum operational efficiency, this unit replaces traditional complex control panels with a modern, high-resolution touch-screen interface. It allows operators to effortlessly monitor real-time temperatures, pressures, flow rates, and reflux ratios directly on the screen. Equipped with intelligent PLC automation and multi-level safety interlocks, the Touch-Screen Controlled Continuous Distillation Unit ensures stable, unattended long-term operation while delivering highly reproducible purity data for commercial production and process optimization.

What is a Touch-Screen Controlled Continuous Distillation Unit?

A Touch-Screen Controlled Continuous Distillation Unit is a specialized chemical separation apparatus that operates on a continuous fractional distillation principle, fully managed through a digital Human-Machine Interface (HMI). The feedstock is continuously metered into the system, where vapor undergoes repeated condensation and revaporization across fractionating columns to separate multi-component mixtures. The defining feature of this unit is its smart touch-screen control system, which provides visual flow diagrams, real-time data trending, and one-touch parameter adjustments. This seamless integration of hardware and software makes it an ideal platform for modern laboratories and pilot plants seeking high-precision separation with minimal manual intervention.

Technical Specifications

What are the characteristics of the equipment?

● Intuitive HMI Operation: The high-resolution touch-screen provides a user-friendly graphical interface, allowing operators to easily set parameters, view real-time curves, and manage alarms without complex programming.

● Automated Continuous Processing: Designed for true continuous operation, ensuring consistent product quality and high energy efficiency compared to traditional batch systems.

● Data Logging & Traceability: The touch-screen system automatically records historical data (temperature, pressure, flow) and allows one-click export via USB for comprehensive quality traceability.

● Multi-Level Safety Interlocks: Integrated with the PLC, the touch-screen displays real-time safety statuses, triggering automatic shutdowns for over-temperature, over-pressure, or dry-heating conditions.

● Modular & Customizable: Flexible integration of preheaters, vacuum systems, and automated fraction collectors to meet specific continuous separation requirements.

Usage Precautions

● Screen Protection: Avoid touching the screen with sharp objects or wet hands. Use the provided stylus or clean fingers to prevent damage to the capacitive/resistive layer.

● Inert Purging: Always purge the system with an inert gas (N2) before heating and before introducing reactive or flammable feedstocks to prevent explosive mixtures.

● Gradual Heating: Utilize the programmable heating ramp rates on the touch-screen to avoid sudden vaporization and column flooding, especially during system startup.

● Regular Calibration: Periodically verify the accuracy of the temperature and pressure sensors displayed on the screen against standard instruments to ensure process reliability.

Common Mistakes vs. Correct Methods

● Mistake: Ignoring alarm pop-ups on the touch-screen and forcing the system to continue. Correct Method: Always acknowledge and investigate alarms immediately. The PLC triggers these alerts to prevent equipment damage or safety hazards; bypassing them can lead to severe consequences.

● Mistake: Overloading the feed rate beyond the column's design capacity. Correct Method: Monitor the differential pressure and temperature profiles on the touch-screen. Adjust the feed pump speed via the interface to maintain stable column hydraulics and prevent flooding.

● Mistake: Failing to save recipe parameters after adjustments. Correct Method: After modifying setpoints for a new batch or product, always use the "Save Recipe" function on the touch-screen to prevent accidental parameter loss during power fluctuations.

● Mistake: Shutting down the heating without stopping the feed. Correct Method: Follow the automated shutdown sequence programmed in the HMI. Typically, this involves stopping the feed first, continuing reflux to clear the column, and then cooling the reboiler safely.

Shipping & Packaging

● Professional Packaging: The Touch-Screen Controlled Continuous Distillation Unit is securely packed in fumigation-free export-standard wooden crates. The delicate touch-screen panel and PLC cabinet are heavily protected with shock-proof foam and anti-static film.

● Component Fixation: Internal piping, columns, and electrical components are firmly braced to prevent vibration damage during ocean or air freight.

● Documentation: A comprehensive English operation manual, electrical schematics, P&ID diagrams, and a detailed packing list are included in a waterproof document pouch attached to the crate.

● Global Logistics: We support EXW, FOB, CIF, and DDP terms, providing reliable door-to-door delivery services to facilities worldwide.
