Conical Screw Mixer
Vertical cone screw blender for batch processing powders, pastes and liquids
Conical screw mixer, also known as Nauta Mixer, cone screw mixer, vertical screw mixer, consists of one or two asymmetric screws. The vertical cone screw blender is a batch mixer, specially designed for batch processing of powders, pastes and liquids. The screws rotate around their own axis (rotation) while, with the help of the rotation of the cantilever, they revolve around the central axis of the cone vessel along the inner wall of the vessel (revolution).
Conical Mixer with CIP
S&L conical screw mixer is equipped with a Clean-in-Place (CIP) system to enhance its performance for hygienic production. This system allows for thorough cleaning of the mixer without disassembly. It involves installing washing devices and performing manual preparatory steps to initiate the cleaning process. The CIP system operates in a fully automated mode through programmable logic control (PLC), ensuring complete cleaning. After wet cleaning, it is essential to dry the mixer using air. By utilizing the CIP system, cross-contamination between batches can be prevented, thus ensuring the quality of the finished products.
Conical Mixer with Jacket
The dimple jacket is a commonly used type of jacket for dryer mixers. It consists of a thin external shell attached to the vessel shell using spot welds. The cooling or heating medium flows through the jacket, allowing for temperature control of the mixer. With advancements in material processing, mixers are increasingly being used for multi-functional mixing purposes. A dryer mixer can be utilized for mixing materials with a maximum water content of 70%, which can then be dried through the heating jacket combined with vacuum technology. In some cases, the drying effect can reduce the water content to as low as 0.05%. The basic design of a dryer mixer involves a stationary horizontal cylinder that is loaded from the top and discharged from the bottom. The standard mixing tools are plow-shaped and radiate from a horizontal shaft supported by outboard bearings. Other mixing tool designs are also available to suit specific requirements.
Operating based on the proven "fluidized bed" mixing principle, this dryer maintains the materials in a mechanically fluidized suspended state. This allows for intimate contact between reacting mediums, such as gas-solid or liquid-solid, and facilitates efficient heat transfer between them and the heat transfer surfaces of the mixer.
Cooling or heating: Various types of jackets can be added to the outside of the mixer cylinder to achieve cooling or heating of the materials by injecting cold or hot media into the jackets. Cooling is typically achieved by pumping industrial water, while heating can be achieved by introducing steam or thermal oil.
Conical Mixer with Retractable Rotor
In a hygienic mixing environment, the screw agitator pull-out design is an ideal choice. This design allows for easy access to the mixing chamber, reduces downtime for cleaning, and prevents cross-contamination between batches. The driven system ensures that the top cover and vessel can be easily separated, facilitating efficient cleaning of the mixer. The screw agitator pull-out design is particularly useful for dealing with sticky materials that may adhere to the vessel or agitator. This design provides a good way to ensure complete cleaning, thereby avoiding any potential pollution or cross-contamination issues. Additionally, this design allows for quick and easy receipt changing, enabling users to increase the efficiency of their mixing processes.
- 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.
