TCQY Drum Cleaner
keyword：
info@mission-mac.com
The TCQY Series Drum Grain Cleaner is a robust rotary screen for pre-cleaning grain at the front end of processing lines. It removes oversize contaminants (straw, cobs, corn ears) and light impurities (dust, husks, chaff) via a rotating cylindrical screen. Clean grain passes through while debris discharges separately. Widely used in rice mills, flour plants, corn facilities, and coffee operations.
Throughput ranges from 12 to 80 t/h with multiple model sizes. Simple mechanical design minimizes maintenance; low-power drive reduces operating costs. For coffee processors, it excels at removing jute fibers and twigs from green beans. Screen mesh is selectable by material characteristics, ensuring optimal cleaning efficiency across diverse grain types.
Key Features
High-Output Capacity With Optimized Energy Efficiency
This Grain Drum Cleaner processes 12–80 t/h with only 1.1–4 kW power consumption—exceptional throughput per kilowatt. Low rotational inertia reduces startup energy. Ideal for continuous operation in grain elevators, rice mills, and processing plants where pre-cleaning cannot become a bottleneck. Balances high volume with low operating costs.
Quick-Change Screen System for Process Flexibility
Swap screen meshes without specialized tools or extended downtime. Adapt rapidly between crops (rice, wheat, corn, coffee) or adjust cleaning intensity based on incoming material quality. Various perforation sizes from coarse debris removal to finer impurity separation. The rotary screen simplifies changeovers, reducing maintenance time while achieving optimal cleaning for each batch.
Simple Construction for Easy Installation and Minimal Maintenance
Few moving parts, modular sections for straightforward on‑site assembly, and accessible inspection points. Low maintenance requirements and reduced spare parts inventory. This drum pre-cleaner delivers excellent ROI for facilities needing reliable, continuous pre‑cleaning without constant supervision or service interruptions.
Gentle Product Handling With Effective Impurity Removal
Calibrated low‑speed tumbling cascades grain, preserving kernel integrity—critical for rice, coffee beans, and other delicate products. Effectively separates oversize debris (straw, cobs, twigs) and light impurities (dust, chaff). The Drum Cleaner prevents breakage and cracking while ensuring thorough cleaning, maintaining product value and roast quality.
Versatile Applications Across Multiple Grain Types
Handles rice, wheat, corn, coffee, soybeans, canola, and barley. Models TCQY80 through TCQY180 cover 12–80 t/h. Excels at removing jute fibers and twigs from green coffee beans before roasting. Serves as a standardized pre‑cleaning solution across intake points or multiple processing lines, adapting to diverse commodities.
Durable Construction With Optional Corrosion Protection
Carbon steel with anti‑corrosion coating for indoor applications; optional stainless steel for high‑humidity, wash‑down, or acidic environments. High‑strength perforated drum, sealed bearings against dust ingress. This cleaning drum ensures long service life and reliable performance in demanding grain processing conditions, reducing replacement frequency and maintenance costs.

FAQ
What is a drum cleaner used for in grain processing?
A drum cleaner removes large impurities such as straw, cobs, corn ears, and light contaminants like dust and husks from grains before main cleaning or milling. This protects downstream equipment and improves final product quality.
How does the TCQY rotary drum screen work?
Material enters the rotating cylindrical screen. As the drum turns, oversize particles travel to the discharge end while smaller, clean material falls through the screen openings. The gentle tumbling action minimizes grain damage.
How to choose the right screen mesh for my application?
Select mesh size based on the target impurities and desired product purity. Larger openings (10-15mm) for coarse pre-cleaning to remove straw and cobs; smaller openings (2-6mm) for finer separation. We can assist with recommendations based on your material.
Can the drum cleaner be used for coffee beans?
Yes. The TCQY series is well-suited for green coffee bean cleaning, effectively removing jute fibers, twigs, stones, and other foreign materials that could affect roast quality and flavor.
How often does the drum screen need to be replaced?
Screen life depends on throughput volume and material abrasiveness. With typical grain processing, screens last 6-12 months. We recommend weekly visual inspections and replacement when wear affects cleaning efficiency.
Is the drum cleaner suitable for organic grain processing?
Yes. The TCQY series is frequently used in organic grain facilities. Stainless steel construction options are available to meet organic certification requirements for ease of cleaning and contamination prevention.
