Twin-shaft paddle mixer in feed production: How to effectively deal with the problem of barrel and paddle residue?

In the process of feed production, raw materials go through multiple links such as crushing, batching, and mixing, and finally become nutritionally balanced feed products. As the core equipment in the mixing link, the performance of the twin-shaft paddle mixer directly affects the mixing uniformity and production efficiency of the feed. However, the diversity and complexity of raw materials often lead to residual materials on the barrel and paddles. These residues will not only reduce the mixing efficiency, but also become a breeding ground for bacteria, posing a serious threat to feed quality.

Decrease in mixing efficiency: Residual materials will occupy the effective mixing space on the barrel and paddles, reduce the mixing area of ​​newly added raw materials, and thus reduce the mixing efficiency. Especially when the formula is changed or batch production, residual materials may cause uneven distribution of the new formula ingredients, affecting the overall quality of the feed.
Damage to feed quality: Residual materials may contain ingredients that have deteriorated or are not suitable for the current batch. After mixing with new raw materials, they will directly affect the nutritional value and palatability of the feed. In addition, residual materials may also become a breeding ground for microorganisms such as bacteria and mold, resulting in excessive feed hygiene indicators and affecting animal health.
Equipment maintenance and cost increase: Long-term accumulation of residual materials will increase equipment wear and corrosion and shorten equipment life. To ensure feed quality and equipment performance, frequent shutdown cleaning and maintenance will increase production costs and time costs.
Faced with the challenge of residual materials on the barrel and blades of the twin-shaft paddle mixer, regular cleaning and intelligent maintenance have become key strategies to ensure efficient operation of equipment and feed hygiene and safety.
Regular cleaning: Building standardized processes
Develop a cleaning plan: Develop a detailed cleaning plan based on production frequency, raw material characteristics and equipment status. The plan should include cleaning cycles, cleaning methods, cleaning agents used, and inspection and acceptance criteria after cleaning.
Choose the right tools: Choose cleaning tools that are suitable for the shape of the barrel and blades, such as high-pressure water guns, soft brushes, special cleaning agents, etc., to avoid damage to the equipment.
Implement thorough cleaning: During the cleaning process, ensure that every corner of the barrel and blades is thoroughly cleaned, especially the root of the blades, the barrel connection and other areas prone to residue. After cleaning, rinse with clean water and dry properly to prevent corrosion caused by residual moisture.
Record and evaluation: After each cleaning, the cleaning time, method, cleaning agent used and cleaning effect should be recorded, the effectiveness of the cleaning plan should be evaluated regularly, and adjustments and optimizations should be made based on the evaluation results.
Intelligent maintenance: Improve maintenance efficiency and accuracy
Remote monitoring and early warning: Use the Internet of Things technology to remotely monitor the operating status of the twin-shaft paddle mixer, monitor key parameters such as equipment temperature, vibration, and pressure in real time, and issue an early warning immediately if an abnormality is found, providing data support for timely maintenance.
Predictive maintenance: Based on big data analysis, equipment operation data is mined and analyzed to predict equipment failure trends, and maintenance plans are formulated in advance to avoid downtime losses caused by sudden failures.
Automated cleaning system: Develop automated cleaning systems, such as automatic cleaning nozzles, rotating cleaning brushes, etc., to reduce the labor intensity and time cost of manual cleaning and improve cleaning efficiency and consistency.
