Paddle Mixer
Industrial horizontal mixer for blending dry powders and liquid additives
S&L paddle mixer, also called fluidized zone mixer, is an industrial mixer for blending dry powders and liquid additives. It consists of a horizontal cylindrical vessel, drive unit, and double shaft paddle, and can be equipped with a lump breaker. During operation, the two shafts with counter-rotating blades rotate to different sides, driving the paddle at different angles to circulate and flip the materials along the axial and radial directions. Under the effect of high linear speed, the materials are thrown up and fall down in a weightless (i.e., zero-gravity) state.
Mixer with Retractable Rotor
The retractable rotor mixer has been developed to meet the needs of specific applications and industries. In cases where manual or CIP cleaning cannot thoroughly remove any materials that may have become stuck to mixing elements or in hard-to-reach areas, the shaft can be completely retracted for further cleaning. This design enables customers to entirely solve the problem of cleaning viscous materials and performing maintenance tasks in the future. The unique design reduces downtime for cleaning and minimizes the potential for cross contamination. An easy to access mixing chamber ensures a hygienic mixing environment.
Working Principle
The retractable rotor mixer is equipped with a quick clamp structure between the end plate and end flange of the vessel body. The shaft can be conveniently and quickly opened away from the vessel. The input shaft connects to the reducer and is held in place by the reducer bearing, while the other side of the shaft is positioned by two bearings. The rail guide ensures that the shaft can be fully opened and driven by a motor or manually operated. However, a PLC control system is required to operate the machine, and a position sensor is needed to ensure that the shaft stops at the same position if it needs to be pulled open.
CIP
S&L paddle mixers are able to achieve optimal performance for hygienic production by implementing a Clean-in-Place (CIP) system. This feature can be added to all of our horizontal mixers. CIP is an efficient cleaning process that requires some manual preparation steps, such as installing a washing device. Once installed, the system performs a complete cleaning in fully automatic mode through PLC technology. Drying with air is necessary after wet cleaning. With no cross-contamination between batches, you can be assured of the quality of your finished products.
- S&L paddle mixer has a super large maintenance door that facilitates maintenance.
- The large maintenance door has a small observation window, which allows for real-time monitoring of the mixing equipment's operation.
- This mixer can realize large batch process with high mixing output.
- Continuous blending or batch blending method: Batch processing allows for traceability.
- Batch size: It is important to find the right balance, as an excessively large batch may result in uneven mixing.
- Mixing time: Shorter mixing times lead to lower processing costs and reduced degradation of sensitive materials. However, a balance must be struck between mixing uniformity and cycle time.
- Power consumption: Energy efficiency is crucial. S&L has extensive experience in designing energy-efficient mixing and blending systems.
- Easy discharge: Discharge capability is one of the key functionalities of batch mixers. It is essential to ensure complete discharge of the blended material without any residual.
- Easy cleaning: Proper cleaning is vital to an equipment for mixing and blending different materials. S&L industrial mixers & blenders are integrated with CIP (Clean-in-Place) systems for easy cleaning.
