Thresher Drum

Thresher Drum Function and Working Method

The Thresher Drum, an essential component in a thresher drum palm oil mill system, operates by utilizing a rotating drum equipped with supper wheels. Sterilized palm fruit bunches are fed into the drum, where the rotating action and the presence of the supper wheels help to thresh and separate the individual fruits from the bunch. The design of the drum and the configuration of the supper wheels ensure that the fruits are gently separated without excessive mechanical damage, which is crucial for maintaining the quality of the fruit and the subsequent oil extraction process.

Thresher Drum Material and Construction

Constructed from carbon steel, the Thresher Drum combines strength and durability. Carbon steel is chosen for its excellent mechanical properties, including high tensile strength and wear resistance, making it ideal for withstanding the rigors of continuous use in a palm oil mill environment. The supper wheels are also made from a durable material to ensure long - term reliable operation.

Thresher Drum Key Specifications

• Size: Available in lengths of 3 meters and 6 meters to accommodate different production capacities and facility layouts.

• Supper Wheel: Equipped with 8 units of 220 mm diameter supper wheels, which assist in the gentle separation of fruits from the bunches.

• Driver Model: The thresher drum is driven by a motor coupled to a gear reducer via a fluid coupling. The gear reducer output shaft is connected to the thresher shaft by a flexible coupling system, ensuring smooth and efficient power transmission.

• Capacity: Designed to handle a capacity of 45 tons per hour, making it suitable for medium to large - scale palm oil processing operations.

• Power: Equipped with a motor rated at 1450 rpm, 18.5 kW, 380 V, and 50 Hz, providing sufficient power for reliable and high - performance threshing.

• Rotational Speed: Operates at a rotational speed of 21 rpm, ensuring efficient fruit separation while maintaining gentle handling of the fruit bunches.

Thresher Drum Performance Advantages

• Efficient Threshing: The combination of the rotating drum and supper wheels ensures effective and rapid separation of individual fruits from sterilized bunches, maximizing throughput and minimizing processing time.

• Durable Construction: The carbon steel build and robust design provide long - term reliability and minimal maintenance requirements, even under continuous and demanding operating conditions.

• Gentle Fruit Handling: The design of the supper wheels and the controlled rotational speed help to reduce mechanical damage to the fruits, preserving their quality and integrity for subsequent processing steps.

• High - Throughput Capacity: With a capacity of 45 tons per hour, the Thresher Drum is suitable for integration into high - volume palm oil processing facilities, ensuring it can keep up with the output of sterilizers and other upstream equipment.

Thresher Drum Applications

The Thresher Drum is a key piece of equipment in palm oil mills and processing plants. It is typically installed after the sterilization process to separate the sterilized fruit bunches into individual fruits. This step is essential before the fruits can be further processed for oil extraction. Its design and specifications make it suitable for integration into both new palm oil processing facilities and existing mills looking to enhance their threshing efficiency and fruit quality. By effectively separating the fruits, the Thresher Drum contributes to the overall efficiency and productivity of the palm oil production process.
