In the field of syrup production in the food industry, with the diversification of products and the increasing demand for high concentration products, stirring equipment is facing the process challenge of higher viscosity media. A food enterprise in Zhejiang Province used a reaction kettle (diameter 2.8 × 3.2 m) in its syrup workshop. The original paddle stirrer design was suitable for material viscosity of 800-1000 cP. During the preparation of high viscosity syrup, the stirring shaft bent or even broke, seriously affecting the stability and safety of production.
To solve the above problems, Chuanneng Carbon and (Beijing) Environmental Technology Co., Ltd. customized an upgrade plan for the enterprise, using the MJN full flow mixing system (model: MJN-1050/3-11), which greatly increased the equipment's stirring viscosity adaptability range to 54000 cP, effectively meeting the process requirements of high viscosity syrup mixing.
Comparison of equipment parameters
project | Original paddle mixer | MJN-1050/3-11 |
Applicable viscosity range（cP） | 800-1000 | ≤54000 |

Core advantages of MJN full process mixing system
Strong adaptability to mixing high viscosity syrup
Designed for high viscosity up to 54000cP, it can stably handle high concentration syrup preparation conditions.
High Efficiency and Energy Saving
By adopting a variable cross-section blade design, the motor power has been reduced from 15kW to 11kW, energy consumption has been reduced by about 26.7%, and it is expected to reduce carbon emissions by 9.53 tons per year.
More reasonable structure and stable operation
Adopting a low shear axial flow blade design, combined with a three-dimensional modeling optimized blade structure, effectively covers the mixing area inside the kettle, avoids local sedimentation, and ensures uniform mixing of materials.
Improvement effect
After the equipment renovation was completed, it has been running stably for one year, with improved mixing efficiency and smooth operation. The mixing cycle has been shortened by about 1 hour per tank, and the customer is satisfied with the performance of the equipment.
