Product Overview
This machine provides a small-batch platform for investigating ingredient incorporation, emulsification, thermal processing and vacuum treatment. Its counter-rotating anchor and central paddle arrangement supplies bulk mixing, while the bottom rotor-stator homogenizer applies localized high shear and drives material through the external circulation route.
For cosmetic cream, lotion and skin-care development, the system can help evaluate formulation changes under documented processing conditions. A 10L oil preparation tank supports separate oil-phase work; no integrated water preparation pot is confirmed.
Selected ointment and pharmaceutical formulation duties may also be evaluated against product viscosity, material compatibility and cleaning requirements. The application description does not establish sterile processing, regulatory approval or suitability for every pharmaceutical product.
The confirmed heating arrangement uses external steam, with electric heating available as an alternative. Hydraulic head lifting provides vessel access, while electric tilting and the bottom ball valve offer different discharge arrangements. Siemens PLC and HMI provide the specified control platform.
The listed working range is 5–20L within a 30L total vessel capacity. Trials should assess the intended batch volume, circulation behavior and recoverable sample quantity rather than vessel capacity alone.
Machine Configuration
The main vessel combines a steam-heated jacket, insulation and a hydraulically lifting head. A counter-rotating anchor agitator with a central paddle and PTFE wall scrapers provides the specified bulk mixing arrangement.
The bottom-entry rotor-stator homogenizer processes material and supplies conveying action into the external circulation route, which returns product to the main vessel. The final drawing should identify the outlet, return point, valves and cleaning route.
A separate 10L oil tank supports ingredient preparation. Siemens PLC and HMI coordinate the supplied functions through the agreed control program.
Electric tilting and a bottom ball valve provide the confirmed discharge arrangements; an external transfer pump is optional. The caster-mounted base supports planned repositioning under the approved handling procedure. Electric heating is an alternative configuration. Seal support, steam services, cooling connections and any external cleaning equipment require a defined supply schedule.

Working Principle
Development work begins with a defined formulation and trial objective. Ingredients requiring separate oil-phase preparation can be handled in the supplied oil tank, while any separately prepared water phase needs an external arrangement.
After charging, the anchor and central paddle operate in the supplied counter-rotating arrangement. PTFE scrapers act along the vessel wall, while the jacket transfers heat from the selected steam service into the batch. Operating settings follow the ingredient sequence and permitted thermal conditions.
Material entering the bottom rotor-stator homogenizer experiences localized shear. The homogenizing head also provides the conveying action that moves material through the external circulation path and back into the main vessel. Actual circulation depends on the working head, product and pipework; rpm alone does not establish flow or pass count.
Vacuum is applied at the stages defined by the trial method. The operator or supplied program coordinates ingredient addition, agitation, homogenization and thermal conditions according to the agreed control functions.
Cooling proceeds through the selected jacket-water service where required. Heat-sensitive ingredients may enter during a separately defined finishing stage.
Once the sample meets the trial endpoint, the machine is brought to the approved discharge condition. Product leaves through the bottom ball valve or electric tilting arrangement, with an external transfer pump optional. The head-lifting and tilting sequences must follow the manufacturer’s pressure-equalization and operating procedures.

After-Sales & Technical Support
🔧 Common Problems
Possible observable symptoms include inconsistent samples, visible agglomerates, uneven product movement, excessive foam, retained air, unexpected viscosity changes or differences between repeated trials. Circulation-related observations may include weak return flow, intermittent movement or a meaningful quantity of retained material after discharge. Operators may also observe slow heating, differing temperature readings, unstable vacuum indications, abnormal agitator or homogenizer noise, drive trips, seal leakage or residue remaining after cleaning. Access-related observations may include irregular hydraulic lifting or difficulty completing the intended tilting movement. These are potential observations rather than confirmed defects. Record the batch quantity, formulation version, ingredient stage, settings and utility conditions when investigating a symptom.
