Discover the Vertical Mixing Dryer

Meet the Vertical Mixing Dryer – your versatile solution for efficient plastic material handling. Also known as a lifting stirring dryer or granular blending machine, this powerhouse uses rotating mixing blades to expertly agitate plastic raw materials, ensuring rapid and uniform mixing of granules. It’s an indispensable partner for extruders, injection molding machines, and granulating machines, perfectly designed for blending and coloring various plastic granules. Need mobility? The base can be optionally equipped with casters for easy movement around your workspace. Enjoy a sealed, secure, and reliable mixing process that delivers consistent results quickly. Plus, with its built-in timer, you have full control over the mixing duration. This machine isn’t just functional; it boasts even mixing, a space-saving compact structure, an attractive modern design, and is incredibly easy to assemble, disassemble, and clean.

What Can It Do For You? Primary Functions

The Vertical Mixing Dryer is a dual-purpose workhorse designed to streamline your plastic processing. Its core functions are:

• Efficient Drying: Utilizes hot air to thoroughly dry plastic granules, removing moisture effectively.
• Uniform Blending: Seamlessly mixes plastic granules with various colorants, functional masterbatches, and fillers, ensuring homogeneity.

By employing robust rotating mixing blades, it stirs and tumbles plastic materials for rapid, consistent mixing, making it a vital auxiliary component for injection molding and granulation lines.

How Does It Work? The Working Principle

The magic happens through a clever combination of mechanical movement and controlled heating. Here’s the process:

1. Plastic granules are introduced via the feed hopper.
2. The spiral blades gently push the material upwards along their surface to the top of the barrel.
3. At the top, centrifugal force disperses the granules in an umbrella pattern, causing them to cascade down around the barrel walls.
4. Material reaching the bottom is automatically fed back into the vertical screw conveyor to repeat the lifting and mixing cycle.
5. Simultaneously, a blower sends air through an electric heating box. This air, precisely heated and controlled by a temperature controller, permeates the layers of granules.
6. As the granules continuously cycle and descend, the hot air efficiently exchanges heat and carries away moisture, completing both the drying and mixing processes in one seamless operation.

Key Features & Benefits

Our Vertical Mixing Dryer is packed with features designed for performance, durability, and ease of use:

• ✓ Premium Stainless Steel Construction: Both the mixing blades and barrel are crafted from high-quality stainless steel, ensuring easy cleaning, preventing contamination, and offering excellent durability.
• ✓ Energy-Efficient Drying: Features an insulating layer within the barrel (standard on most models) to minimize heat loss, boosting drying efficiency and saving energy. The optional heating function uses reliable stainless steel heating rods.
• ✓ Precise Temperature Control: Equipped with a PID intelligent temperature controller and strategically placed temperature points for accurate, automatic control over heating temperature and time.
• ✓ Quiet & Efficient Mixing: The stainless steel screw-lift mechanism provides powerful yet quiet mixing with low power consumption, delivering uniform blends every time.
• ✓ Robust & Operator-Friendly Design: A sturdy steel base supports heavy loads, while the observation window allows clear monitoring. The low feed port design minimizes operator strain and boosts productivity.
• ✓ Optimized Airflow: A centrifugal fan delivers high-volume hot air efficiently, reducing energy loss and enhancing the heating effect significantly.

Easy Maintenance & Operation Guide

Pre-Operation Checks:

• Confirm mixing blades are secure and properly lubricated.
• Connect power correctly. Open the lid and visually inspect the barrel for any foreign objects.
• Verify the power supply voltage matches the machine’s nameplate requirements.
• Perform a brief no-load test run. Check for smooth operation and confirm the correct rotation direction of the mixing blades before adding materials.
• Ensure all rotating parts move freely and clear any obstructions around the main shaft inside the barrel.

Operating Instructions:

• Position the machine stably. Use anchor bolts for securing if required.
• When connecting three-phase power, carefully verify the motor’s rotation direction is correct.
• After starting, let the machine run empty for 2-5 minutes to confirm normal operation before introducing materials.
• For Mixing/Coloring: Set the desired time on the timer and temperature on the controller (if heating). Start the machine. It can stop automatically based on settings or be manually stopped/restarted.
• For Drying: Set the target temperature on the controller and the drying time. The machine will operate until the cycle completes.
• To stop, use the designated stop mode or press the OFF button.

Care and Maintenance:

• Safety First: Always disconnect the main power supply before performing any maintenance or cleaning.
• Lubricate bearings weekly using ZL-2 lithium-based grease or equivalent.
• When changing colors or materials, thoroughly clean all contact parts using white mineral oil or diesel to prevent cross-contamination.
• If an electrical protection fault occurs, do not attempt to bypass it. Contact a qualified technician to inspect, repair, and resolve the issue before resuming operation.
