Hopper Type Plastic Dryer 75kg by Yokoma Stainless Steel Dryer

Description

Product Overview

The Yokoma Hopper Type Plastic Dryer is engineered to meet the demanding moisture‑control requirements of modern polymer processing facilities. With a generous 75 kg (165 lb) hopper capacity, the unit can handle large batches of granules, pellets, and powders, reducing the number of drying cycles and increasing overall throughput. The core of the dryer is a stainless‑steel barrel that resists corrosion, deformation, and wear, ensuring a long service life even under continuous operation. A high‑efficiency 6 kW motor drives a powerful fan that circulates uniformly heated air throughout the chamber, delivering rapid and even moisture evaporation across the entire material load.

Temperature regulation is achieved through an accurate proportional‑deviation controller, which maintains the set point within a narrow tolerance, preventing overheating or under‑drying of sensitive polymers. The vertical design maximizes space utilization, making the dryer suitable for compact laboratory benches as well as larger production floors. All critical components—including heating elements, fan blades, and the detachable barrel—are designed for easy access, allowing routine maintenance and thorough cleaning without disassembly of the entire machine.</n

Usage

This dryer excels in environments where material moisture directly impacts product quality, such as injection molding, extrusion, and additive manufacturing. Operators can load wet granules directly from bulk containers or transfer them from drying tunnels, then set the desired temperature and drying time via the intuitive control panel. The uniform hot‑air flow eliminates hot spots, ensuring that each particle reaches the target moisture level, which is critical for achieving consistent melt flow index and preventing defects like short‑shots or surface blemishes.

Typical applications include drying poly‑propylene (PP) for automotive interior components, polyethylene (PE) for packaging films, acrylonitrile‑butadiene‑styrene (ABS) for consumer electronics housings, and specialty engineering plastics used in medical devices. The machine’s robust construction also makes it suitable for research laboratories where precise control of drying parameters is required for experimental reproducibility. Whether used in a small‑scale pilot plant or a full‑scale production line, the dryer’s flexible design accommodates a wide range of batch sizes and material types.</n

Why Choose Us

Choosing the Yokoma Hopper Type Plastic Dryer means investing in a solution that combines durability, performance, and user‑centric design. The stainless‑steel barrel not only resists chemical attack from aggressive polymer additives but also maintains dimensional stability, which is essential for consistent airflow and temperature distribution. The 6 kW motor provides ample power to drive the fan at high speeds, yet the unit operates quietly, minimizing acoustic disruption in shared workspaces.

Yokoma’s commitment to quality is reflected in rigorous testing procedures that verify temperature uniformity, airflow velocity, and energy consumption under various load conditions. Each dryer is shipped with a comprehensive set of documentation, including installation guides, operating manuals, and preventive maintenance schedules. In addition, Yokoma offers responsive technical support and a warranty that covers core components for three years, giving customers confidence that their investment is protected.

Environmental responsibility is also a priority. The dryer’s efficient heating system reduces energy waste, and the detachable barrel design encourages proper cleaning, extending the lifespan of the equipment and reducing the need for replacement parts. By selecting this dryer, manufacturers can achieve lower operational costs while maintaining the high product quality demanded by today’s competitive markets.</n

FAQ

What types of polymers can be dried with this machine?

The dryer is suitable for a wide range of thermoplastic polymers, including polypropylene (PP), polyethylene (PE), acrylonitrile‑butadiene‑styrene (ABS), polycarbonate (PC), and engineering plastics such as nylon and POM. It can also handle moisture‑sensitive additives and color concentrates that are commonly used in specialty formulations.

How do I clean the barrel after a drying cycle?

The barrel is designed to be detachable. Simply loosen the securing bolts, lift the barrel from the base, and use a soft brush or compressed air to remove residual granules. For thorough cleaning, a mild detergent solution can be applied, followed by a rinse with deionized water and complete drying before reassembly.

Can the dryer be integrated into an automated production line?

Yes. The control panel includes standard communication ports that allow integration with PLCs and factory automation systems. Custom interfaces can be programmed to trigger drying cycles based on upstream sensor data, ensuring seamless material flow from storage to processing equipment.

What safety features are included?

The unit is equipped with an over‑temperature protection relay that shuts down the heating element if the set temperature is exceeded. Additionally, the machine has a grounded metal enclosure and safety interlocks that prevent operation when the barrel is not properly seated.

Is there a recommended maintenance schedule?

Yokoma recommends a quarterly inspection of the fan blades, heating elements, and temperature sensors. The barrel should be cleaned after each batch to prevent material buildup. A full service, including lubrication of moving parts and verification of electrical connections, is advised annually to maintain optimal performance.
