The cylinder round sifter is new sieve equipment after the vibrating sieve and the ordinary net drum sieve. It is very common in the nut food processing industry and widely used for the sieve of all kinds of solid materials. Because of its unique structural characteristics, it solves the shortcomings of other types of screening machines. And this sifter is the preferred equipment in the nut food manufacturing industry.
The cocoa bean cylinder round sifter is not only used for screening cocoa beans but also for coffee beans, nuts, peanuts, almonds, walnut kernels, and other granular materials.
The machine frame and drum are made of food-grade stainless steel 201, featuring a sturdy structure, wear and corrosion resistance, and easy cleaning.
The main function of this machine is to separate cocoa beans from cocoa pods. Through the rotation of the drum and the sieve holes, it classifies and automatically sorts raw materials by different particle sizes with high efficiency. The machine provided by Taizy can screen 300–2000 kg/h, making it suitable for small, medium, and large-scale enterprises.
The composition of the cylinder round sifter
This kind of sieving machine has a simple structure. Which is mainly composed of a motor, roller device, sieve, frame, feeding port, and discharging port. The motor drives the drum device to move around the axis through the coupling to realize the sieving effect. It is generally used in combination with a lifting and cutting machine.
Stainless Steel Drum: Made of thickened stainless steel 201 perforated plate, sturdy and durable, with evenly distributed sieve holes and a screening accuracy of over 90%.
Discharge Hopper: Constructed with 201 stainless steel, it guides the screened cocoa beans of the same diameter into separate collection bins, preventing material mixing.
Frame: Entirely made of painted carbon steel with movable caster wheels, making it easy to move within the workshop.
Power System: Driven by a 1.1 kW motor to ensure stable drum rotation, featuring low operating noise and easy maintenance.
The characteristics of the cylinder round sifter
- High screening efficiency. With a screening rate of over 90%, the machine is equipped with a comb-type screening device, ensuring efficient separation regardless of how the materials are mixed.
- Compared with other types of screening machines, this machine adopts a large-size cylindrical screening component, providing a larger effective screening area and more sufficient contact between materials and the screen mesh, thereby significantly improving screening efficiency and overall output.
- During operation, the equipment can be optionally equipped with a fully enclosed dust cover to prevent dust leakage during the screening process, ensuring a clean and pollution-free workshop environment, and better meeting modern food processing hygiene requirements.
- The machine runs smoothly with low noise. Thanks to the relatively low drum speed and the external protective cover design, operating noise is further reduced, creating a quiet and comfortable working environment.
- In addition, the machine is carefully designed for convenient operation and maintenance: observation windows are installed on both sides, allowing operators to monitor material flow and screening in real time; a top inspection port is provided for maintenance and cleaning without shutting down the machine, ensuring production continuity and stability.
The application of cylinder round sifter
In the production line of cocoa processing, often used the cylinder round sifter. Which can not only remove the stone in the early stage of the cocoa bean processing but also grade the cocoa bean after the peel. Second, in addition to the cocoa beans, the machine can also use to screen most nuts.
Industries of application
- Cocoa processing plants: Used for particle size grading before roasting and grinding.
- Chocolate manufacturers: Ensures uniform raw material particles, enhancing chocolate texture and taste.
- Nut and bean processing industry: Sorts nuts and beans by size, improving product marketability.
- Coffee processing plants: Used for grading coffee beans by size.
In addition, it can also use in the chemical industry, building materials, metallurgy, and other industries. Mainly used for material screening and grading treatment, so as to improve the quality of materials.

How a cocoa bean sifter works？
- Material Feeding: The material enters the interior of the cylinder sifter through the feeding port.
- Sieving Process: The cylinder begins to rotate, and the material moves along the length of the cylinder while being subjected to centrifugal force. Smaller particles pass through the sieve or screen, while larger particles remain on the cylinder surface.
- Grading and Separation: Based on the size of the sieve or screen openings, the material is classified into different particle size levels. Fine particles pass through the openings, whereas larger particles continue moving along the cylinder surface.
- Material Discharge: After sieving, materials of different sizes move forward along the cylinder and are discharged through the corresponding outlets.
Cocoa bean sifter buying guide
- Capacity Matching: Choose equipment suitable for your factory’s scale to avoid insufficient output or wasted capacity.
- Sieving Accuracy: Select the appropriate sieve mesh size according to the cocoa bean size and grading requirements.
- Hygiene and Maintenance: Food-grade stainless steel construction and easy-to-clean design help prevent contamination.
- Continuous Operation Capability: For large-scale production, it is recommended to choose a cylinder sifter or multi-layer vibrating sieve.
- Dust Control: Optional dust covers or exhaust interfaces can reduce dust pollution.
- Noise Control: For factories with strict working environment requirements, low-noise designs are preferred.
