Chicken powder has good fluidity and is finely ground from a variety of ingredients. The particles are very fine. Therefore, the selection of inclined screw conveyor for chicken powder is crucial. It combines the working principle of traditional screw conveyors, and pushes the material forward by the rotation of the spiral blades in a closed pipe, and efficiently and stably conveys chicken powder at a certain angle (generally 15°~45°).

What is the difference between a screw conveyor and an auger?

Screw conveyor: Screw conveyors are mainly used to continuously convey powdered, granular or small block materials in relatively closed pipes. Through the rotation of the spiral blades, the material is pushed along the axial direction to achieve horizontal, inclined or vertical material transfer, emphasizing continuous conveying and displacement.

Auger: Augers are mainly used in geological exploration and foundation engineering for drilling operations. For example, they are used to dig underground pile holes in construction projects and to dig holes when planting trees in agriculture. Through the high-speed rotation and axial propulsion of the spiral blades, solid media (such as soil, rock, concrete) are cut, crushed and drilled.

What is the role of the inclined screw conveyor in the chicken powder production line?

Material conveying and lifting: The inclined screw conveyor is used to transport chicken powder from low places (such as mixers, storage silos) to high-level equipment (such as packaging machines, screening machines or drying equipment). Chicken powder is a fine granular material, which is suitable for continuous conveying by the rotating blades of the screw conveyor.

Process connection: In the chicken powder production line, the screw conveyor plays the role of connecting different process links. For example: the mixed chicken powder is transported from the mixer to the drying equipment. The dried chicken powder is transported to the screening machine for particle screening. The screened finished product is transported to the packaging machine for packaging.

Prevent material scattering and contamination: Inclined screw conveyors usually adopt a closed tubular structure, which can effectively prevent chicken powder from scattering or being contaminated by the outside world during transportation, and maintain the hygiene and quality of the material.

Adapt to the characteristics of chicken powder: Chicken powder has a certain fluidity, but it may also produce slight stickiness due to humidity or different formulas. The design of the inclined screw conveyor can adapt to these characteristics to ensure smooth transportation.

What is the inclination coefficient of the inclined screw conveyor for chicken powder?

For dry, non-abrasive materials such as chicken powder, when the inclination angle β is 0°, ≤5°, ≤10°, ≤15° and ≤20° respectively, the corresponding screw conveyor inclination coefficient C is approximately:

0°: 1.0; ≤5°: 0.9; ≤10°: 0.8; ≤15°: 0.7; ≤20°: 0.65

These coefficients are used to correct the impact of the inclined arrangement of the screw conveyor on the conveying volume. For example, if the conveyor is arranged at an inclination of no more than 5 degrees, its conveying capacity is about 90% of that when arranged horizontally (0 degrees inclination).

Chicken powder is a fine granular material with medium fluidity and is not easy to get stuck, but the conveying capacity is significantly reduced at high inclination (>30°); if a shaftless screw or a stirring blade structure is used, the actual inclination coefficient may be slightly optimized, but it is still recommended to control it below 30°; in the design, the inclination angle, material fluidity, spiral blade form, spiral speed and other comprehensive considerations should be taken into account.

What is the purpose of the inclined screw conveyor for chicken powder?

The inclined screw conveyor plays an important role in the chicken powder production line. It is mainly used to achieve material lifting and conveying. The production of chicken powder usually requires a variety of raw materials (such as monosodium glutamate, salt, starch, etc.). The inclined screw conveyor can stably lift and convey these low-lying powdered raw materials to the feed inlet of the mixer, batching equipment or other processing equipment set above.

In the production process of chicken powder, the material will go through multiple processing stages, such as mixing, granulation, drying, screening, etc. The inclined screw conveyor can serve as an efficient "bridge" between these processes, seamlessly conveying the processed semi-finished chicken powder from the outlet of one device to the entrance of the next device to ensure the continuity of the production process. The final processed chicken powder needs to be packaged. The inclined screw conveyor can smoothly and accurately lift and feed the finished chicken powder output from the production line into the feed port of the packaging machine, thereby ensuring the efficiency and accuracy of packaging.

What is the speed of the inclined screw conveyor for chicken powder?

The speed of the inclined screw conveyor for chicken powder needs to be determined comprehensively based on factors such as the characteristics of the conveying material, the conveying distance, the inclination angle, and the conveying volume requirements. Since chicken powder is a fine-grained, dust-prone, and light-weight food powder, it is necessary to avoid excessive speed when designing the speed, which may lead to: material reflux or slippage; excessive dust; unstable conveying; material stratification or crushing.

Note: The larger the inclination angle, the lower the appropriate speed, which is usually 10%~30% lower than horizontal conveying to increase the "thrust" of the spiral on the material and prevent it from falling back.

Inclined screw conveyors are mainly used for continuous conveying and lifting of materials in chicken powder production lines, connecting various process links, ensuring smooth and efficient production processes, and ensuring the hygiene and quality of materials. Its closed design and flexible inclination adaptability make it particularly suitable for the conveying needs of powdered materials such as chicken powder in the food industry.
