Clay Bath

Clay Bath Function and Working Method

The Clay Bath operates by utilizing a solution gravity kernel - shell separation system. The process involves the use of calcium carbonate (CaCO3) to create a solution with specific density properties. When the mixture of kernels and shells is introduced into this solution, the difference in density between the kernels and shells allows them to separate. The kernels, being lighter, float to the surface, while the heavier shells sink. The stirrer ensures thorough mixing and maintains the solution's homogeneity, while the vibration motor assists in separating and discharging the kernels and shells through the screen.

Clay Bath Material and Construction

The Clay Bath is constructed from a combination of carbon steel and SS304 stainless steel. Carbon steel provides the necessary structural integrity and durability, while SS304 stainless steel is used for components that come into contact with the solution and materials to prevent corrosion and contamination.

Clay Bath Key Features

• CaCO3 Pump: With a capacity of 40 m³/hr, a head of 8 m, and powered by a 4 kW motor operating at 380 V and 50 Hz, it ensures efficient transportation and circulation of the calcium carbonate solution.

• Stirrer: Equipped with a 1.5 kW motor, operating at 380 V and 50 Hz, with a speed of 8 rpm, it maintains the solution's homogeneity and ensures effective separation.

• Screen: Features a SS304 screen with a hole size of φ4 mm, powered by two 2.2 kW vibration motors operating at 380 V and 50 Hz, ensuring precise separation of kernels and shells.

• Capacity: Designed for a capacity of 7 tons per hour, making it suitable for medium- scale palm oil processing operations.

Clay Bath Performance Advantages

• High - Efficiency Separation: The gravity and centrifugal method ensures thorough separation of kernels and shells, producing a high - purity kernel product suitable for oil extraction.

• Durable Construction: The combination of carbon steel and SS304 stainless steel ensures long - term reliability and minimal maintenance requirements.

• Stable Operation: The system is designed for continuous and stable operation, with minimal vibration and efficient power transmission.

• Energy - Efficient Operation: The pump, stirrer, and vibration motors are designed to minimize energy consumption while maintaining high - performance separation.

• Precision Separation: The SS304 screen with φ4 mm holes ensures precise separation, allowing only kernels of the desired size to pass through while effectively retaining the shells.

Clay Bath Applications

The Clay Bath is a key component in modern palm oil mills and processing plants. It is typically installed after the initial dehulling and polishing stages to further refine the separation of kernels from shells. By efficiently separating kernels from shells using the gravity and centrifugal method, the Clay Bath ensures that only high - quality kernels are processed further for oil extraction. This enhances the overall efficiency and yield of the palm oil production process. Its design and specifications make it suitable for integration into both new and existing palm oil processing facilities, contributing to the production of high - quality palm kernel oil.
