Purifier ÇKIS-46/200: The Gold Standard in Flour Milling Quality

In today’s grain processing industry, profitability is directly linked to the extraction percentage of premium grade flour. To achieve superior quality and ideal flour whiteness (low ash content), it is essential to thoroughly separate the pure endosperm from the grain’s outer bran layers. The Purifier ÇKIS-46/200, manufactured by the global leader in milling machinery — ÇİFT KARTAL, is specifically engineered for this critical production stage.

This unit combines the functions of a plansifter with aerodynamic air separation, making it an indispensable asset for high-performance modern mills.

The Role of the Purifier in the Technological Flow

After the grain passes through the initial break systems of the roller mills, an intermediate product is formed — a mixture of semolina, middlings (fine semolina), and bran particles. If this mixture were sent directly to the reduction rolls, the bran particles would be ground along with the endosperm, inevitably degrading the color and baking properties of the final flour.

The Purifier ÇKIS-46/200 eliminates this problem. It receives the fractions from the sifters and grades them by two parameters simultaneously: by size (using sieves) and by aerodynamic properties (using an upward air current). Due to this, the light bran particles are lifted and removed via aspiration, while the heavy, pure semolina passes through the sieves and is directed to the reduction rolls.

Aerodynamics and Multi-Level Sieve System

The efficiency of the ÇKIS-46/200 model is based on a perfect synergy between mechanics and pneumatics.

• 5 m² Sifting Area: The machine is equipped with three layers of sieve frames. Such a large area guarantees high throughput and a thin product layer on the sieves, which is critical for effective air penetration.

• Aerodynamic Balancing: The machine’s air requirement ranges from 40-70 m³/min. Thanks to an ingenious valve system, the operator can precisely adjust the airflow strength for each zone of the sieve frame individually, achieving the ideal “fluidization” of the product.

• Oscillation Mechanism: The machine is driven by two reliable vibration motors with a total power of only 0.4 kW (2 × 0.2 kW). The speed of 590 rpm and an adjustable stroke of 0 to 9 mm ensure the gentle movement of semolina across the sieves without friction, preventing further fragmentation of the bran skins.

Why Invest in the ÇKIS-46/200 by ÇİFT KARTAL?

Integrating this equipment into your production line yields immediate economic benefits:

1. Increased Premium Extraction: Pure semolina is more easily ground into high-quality flour with minimal ash content.

2. Load Optimization: Reduction rolls work more efficiently because they do not waste energy on grinding bran. This reduces roll wear.

3. Energy Savings: The extremely low power consumption (0.4 kW) makes this machine one of the most economical in its class on the global milling equipment market.

Integration and Operational Performance

The ÇKIS-46/200 has well-thought-out dimensions (2800 x 1290 x 1380 mm), allowing it to be easily integrated into both new mill projects and during the modernization of existing lines. A weight of 1300 kg and a solid steel frame using specialized shock absorbers ensure that no vibrations are transmitted to the building’s floors.

We recommend using the purifier in combination with our roller mills and pneumatic conveying systems to create a fully automated and uninterrupted production cycle. The machine’s design ensures easy access to the sieve frames for quick replacement or cleaning, minimizing downtime during maintenance.

Frequently Asked Questions (FAQ)

1. Can the oscillation intensity be adjusted during operation? Yes, the oscillation stroke (amplitude) is adjustable from 0 to 9 mm using the unbalance weights on the vibration motors. This adjustment is done when the machine is stopped. The settings depend on the particle size of the fraction being cleaned and the product’s moisture levels.

2. What aspiration system is required for this machine? For correct operation, the purifier must be connected to the mill’s centralized aspiration system or an individual fan. The required air volume is 40 to 70 cubic meters per minute. For capturing light bran particles removed from the machine, our industrial jet filters are an ideal match.
