Industrial Production Scales Çift Kartal ÇKRK: The Evolution of Precision and Automation

The industrial production scales of the ÇKRK series by the Turkish engineering leader Çift Kartal represent a sophisticated solution for batch weighing of bulk materials in a continuous flow. This equipment is a cornerstone for modern flour mills, feed plants, and grain terminals, where every gram of accuracy directly impacts the overall profitability of the enterprise.

In the era of Industry 4.0, industrial production scales act as the “eyes” of the production line. They enable real-time data collection, minimize human error, and ensure perfect repeatability of technological cycles.

Technical Excellence: Engineering Behind ÇKRK Scales

Every grain elevator or screw conveyor within a facility performs better when the ÇKRK weighing system coordinates the material flow. The design of these scales is a synergy of robust mechanics and high-end electronics.

Load Cell System and Metrological Accuracy

At the heart of the system are high-sensitivity strain gauge sensors (load cells). Unlike legacy mechanical systems, modern industrial production scales convert physical pressure into a digital signal with extreme precision. This allows for an accuracy of ± 50-100 grams per batch of up to 50 kg. These sensors are engineered with high vibration resistance, allowing the scales to be installed near operating machinery without losing measurement integrity.

Intelligent PLC Control

The entire operational logic — from pneumatic valve actuation to calibration — is managed by an industrial Programmable Logic Controller (PLC). This provides the user with the ability to:

• Adjust the speed of weighing cycles.

• Store weighing history by shifts, weeks, or months.

• Seamlessly integrate the equipment into the plant’s SCADA system.

Applications and Line Integration

Implementing conveying and automatic weighing systems is a mandatory requirement for certification under international quality standards like ISO and HACCP. The ÇKRK industrial production scales are ideally suited for the following products:

1. Flour Milling: Tracking various grades of flour, semolina, and bran.

2. Grain Terminals: Monitoring throughput during vessel or rail car loading.

3. Food Industry: Weighing rice, starch, and other powdery ingredients.

4. Feed Production: Precise dosing of components for balanced animal feed formulas.

The Batch Weighing Principle: Step by Step

The ÇKRK operational mechanism follows the “buffer-hopper” principle, allowing for an uninterrupted flow of material supplied by bucket elevators:

• Filling Stage: The product fills the weighing chamber. As the target weight approaches, the pneumatic valve switches to “fine dosing” mode before closing completely.

• Stabilization Stage: The PLC system pauses for a fraction of a second to stabilize sensor readings and record the exact weight.

• Discharge Stage: The bottom valve opens, dropping the batch into the lower hopper. Thanks to a special internal coating, the product does not stick, ensuring the “purity” of every cycle.

• Self-Control Mode: After each cycle, the system automatically verifies the zero mark, eliminating cumulative errors.

8 Strategic Advantages of ÇKRK Industrial Production Scales

1. Full Digitalization: Data transmission capabilities to remote servers via Ethernet or RS485 protocols.

2. Industrial Safety: Integrated aspiration ports prevent the formation of explosive dust-air mixtures.

3. High Throughput: The ÇKRK-50 model provides accounting for up to 15 tons of product per hour.

4. Environmental Protection: All electronic components are shielded against dust and moisture (IP protection).

5. User-Friendly Interface: Operators manage the system via a tactile keyboard with clear visual feedback on the display.

6. Waste Minimization: Precise flow cutoff prevents hopper overflows and spills.

7. Mechanical Reliability: Heavy-duty pneumatic cylinders are rated for millions of cycles without requiring seal replacement.

8. Rapid ROI: Through precise accounting and loss prevention, these scales typically pay for themselves within the first few months of operation.

Maintenance and User Guide

High-quality industrial production scales are an investment that requires minimal but regular care. The Çift Kartal design allows for technical inspections without a total line shutdown:

• Pneumatics: Weekly checks of the moisture separators in the compressed air system are required. Operating pressure must be maintained between 5-7 bar.

• Load Cells: Calibration checks with standard reference weights are recommended once per quarter.

• Hygiene: Due to the absence of “dead zones” in the weighing chamber, the risk of product contamination is virtually zero.

Frequently Asked Questions (FAQ)

How do these industrial production scales react to power surges?

The control unit is equipped with voltage stabilizers and interference filters to protect the PLC. However, we recommend using a UPS for mission-critical lines.

Can the scales be used for oily seeds?

Yes, but for such products, we recommend stainless steel versions with specific hopper angles to ensure better material sliding.

How is the system calibrated?

Calibration is performed via the software on the control panel. The process takes less than 10 minutes and does not require specialized external technicians.
