Rice Flexible Screw Conveyor

The Rice Flexible Screw Conveyor is a device used to transport various types of rice grains. It features a flexible spiral tube that, along with a flexible conduit, transports rice grains from one location to another in a closed, continuous, and smooth manner. It can smoothly transport, load, or fill paddy rice, brown rice, and polished rice. The tube diameter is available in 100mm, 120mm, and 160mm options, with a conveying capacity adjustable from 2 to 15 tons per hour and a conveying distance of approximately 3 to 12 meters. It can be laid horizontally, slightly tilted, or used vertically for short distances. The flexible conduit is made of food-grade thick PU material, which is non-absorbent, non-sticky to rice, and odorless. The inner spiral tube is made of 304 stainless steel, with a smooth and sturdy surface, preventing scratching or crushing of rice grains during transport.

Rice Flexible Screw Conveyor Parts

The components of the Rice Flexible Screw Conveyor are designed to address the characteristics of rice grains: fragility, sensitivity to moisture, and contamination. The power unit uses a geared motor with adjustable speed, allowing for slow and gentle rice conveying and reducing breakage. A baffle plate in the feed hopper prevents rice grains from accumulating and clogging. The flexible conveying pipe is sealed, isolating dust, moisture, and impurities. There are no bearings in the pipe, eliminating concerns about lubricant contamination. The discharge port has a flow rate regulator to control the feeding speed. The entire machine frame is lightweight and sturdy, and some models even have casters for easy movement and repositioning. Parts in contact with the rice grains are made of food-grade materials, are burr-free, easy to clean, and meet grain hygiene requirements.

Benefits of Rice Flexible Screw Conveyor

Using a Rice Flexible Screw Conveyor to convey rice offers numerous advantages, especially in protecting the rice grains, flexible installation, and easy cleaning and maintenance. Rice grains are relatively fragile; in pneumatic conveyors or bucket elevators, high-speed collisions and drops easily break the grains. The flexible screw conveyor gently pushes the grains with its screw, rather than throwing them around, resulting in a smoother transport process, fewer broken grains, higher grain integrity, and a better yield. Factories often have obstructions from pillars, equipment, or pipelines. Flexible conduits can bypass these obstacles, avoiding straight-line installations, saving factory space and reducing modification costs. The equipment has a simple structure, is easy to disassemble, and can be thoroughly cleaned without complicated tools, helping to prevent mixing of different batches of rice and mold growth. The enclosed conveying pipes prevent external dust and insects from entering, and rice flour won't fly out, resulting in cleaner air in the workshop.

Rice Flexible Screw Conveyor Specifications

Rice Flexible Screw Conveyor Price

The price of a Rice Flexible Screw Conveyor is affected by configuration, materials, conveying distance, and capacity requirements. For example, small models with a pipe diameter of around 63mm, a conveying length of 2 to 3 meters, and a small conveying capacity typically cost between $500 and $1,100, suitable for small farmers or workshops processing rice. Medium-sized rice mills typically use equipment with a pipe diameter of 114mm and a conveying length of 6 to 10 meters. Equipped with food-grade stainless steel screws and high-performance motors, these cost approximately $2,300 to $4,100. For large-scale rice industrial applications, pipe diameters may exceed 140mm, and conveying lengths may exceed 15 meters. If explosion-proof motors or wear-resistant materials are added, the price of such customized equipment could range from $4,900 to $9,000.

Rice Flexible Screw Conveyor Conveying Solutions

During rice processing, issues such as moisture absorption, overheating, breakage, and dust are common. The Rice Flexible Screw Conveyor can be adjusted according to site conditions.

Rice is hygroscopic, and in warmer workshops, friction can cause it to overheat, affecting its quality. Therefore, the equipment can be equipped with anti-static, high-temperature resistant hoses, and cooling jackets can be added to the screw to help control the temperature during conveying.

For brown or polished rice containing dust, the equipment can be equipped with dustproof inlets and outlets and filter breathers to balance air pressure and collect dust, significantly improving the cleanliness of the workshop environment. If the production line needs to switch between different grades of rice, the quick-release structure allows operators to remove the screw and hose for cleaning within minutes.

During renovations of older factories, if space is limited, the conveyor can be fixed to a wall, suspended from the ceiling, or mounted on a mobile trolley to serve as a mobile conveyor station, moving between multiple hoppers and reducing the inconvenience caused by dead corners.

The Rice Flexible Screw Conveyor meets the hygiene and gentle handling requirements of rice production. Different pipe diameters can be selected based on production volume; for example, smaller diameters can be used for small-batch processing, while larger diameters can be selected for large production lines. The screw blade curvature and speed are also adjusted according to the characteristics of the rice to reduce compression and collision. Equipment purchase costs and subsequent maintenance expenses are relatively controllable; routine maintenance only requires periodic checks of the motor and screw wear. Whether it's a small processing point or a continuous conveyor system for an automated production line, it can be configured and adjusted according to on-site needs, making the process of rice from raw grain to finished product smoother and reducing breakage and loss.
