Introduction: Choosing between a 50L and 100L pilot vacuum emulsifier comes down to batch volume, viscosity, motor power, tank construction, heating, control, and the utilities your pilot plant can support.
A formula that works in a lab beaker still has to prove itself in a pilot batch. The smaller unit may provide enough representative product at lower raw-material cost, while the larger unit can generate stronger scale-up data if you can justify the larger batch. Flow behavior, water and oil phase volumes, site power, heating source, and control preferences all shape the final choice. A useful quotation connects these variables to the model rather than treating capacity as a standalone number.
How Batch Volume and Viscosity Point to 50L or 100L
Start with the batch you actually need to produce. A 50L pilot vacuum emulsifier fits expensive formulas, early pilot trials, and teams that need to test several small variations before committing raw materials. A 100L unit makes sense when you need more product for stability testing, user trials, filling checks, or when the pilot batch must better represent future production scale. The capacity difference is simple on paper, but the three-tank design makes the choice more practical. The 50L model has a 40L water phase tank and a 20L oil phase tank. The 100L model has an 80L water phase tank and a 40L oil phase tank. If your formula calls for more oil phase than the 20L tank can hold, the 50L system may force you to split or repeat a step. If your water phase is already near 40L, the 100L system gives you more working room and a cleaner pilot batch. Viscosity then tells you how hard the machine has to work. Cosmetic creams, ointments, and fine chemical pastes often sit in the medium-to-high viscosity range, where flow is slow and heat transfer is uneven. When you compare viscosity data, match the units; dynamic and kinematic viscosity are not the same. The Engineering Toolbox viscosity converter is a useful reference for checking unit conversions before you discuss flow behavior with an equipment supplier. A high-viscosity formula rewards a pilot vacuum emulsifier with strong wall scraping, a controllable main agitator, and a homogenizer that can circulate the batch without stalling. A low-viscosity lotion may run comfortably in either size, but a thick paste usually pushes you toward the larger motor set and the larger tank volume.
What Motor Power and Tank Construction Mean for Pilot Production
Motor power is where the 50L and 100L models separate in daily use. The ratings show what the machine can move, how much shear energy the homogenizer can deliver, and what your electrical room must be ready to support.
1. Reading Total Installed Power for 50L and 100L Pilot Units
The PMK-50L has a total installed power of 18kW. The PMK-100L has a total installed power of 31kW. On the 50L unit, the main agitator is 0.75kW at 0–63 rpm, the wall scraper is 0.37kW, the homogenizer motor is 2.2kW, and the hydraulic lift pump is 0.75kW. On the 100L unit, the main agitator is 1.5kW at 0–63 rpm, the wall scraper is 0.55kW, the homogenizer motor is 4.0kW, and the hydraulic lift pump is 1.1kW. The jump from 18kW to 31kW is the main reason a 100L pilot vacuum emulsifier is not just a bigger tank. It needs a stronger electrical supply, and it gives the homogenizer more power to handle a larger batch of viscous cream, ointment, or paste. The homogenizer motor rating is central because it determines how much shear energy enters the batch. If your pilot plant has limited power, the 50L model can be the better starting point. If your batch size and formula demand the 100L working volume, plan the site power around 31kW from the beginning.
2. Why Wall Thickness and Three-Tank Volume Affect Pilot Batch Control
Both models use a 4/3/3 mm wall construction: a 4 mm inner shell, a 3 mm jacket, and a 3 mm outer layer. That construction supports the jacketed heating and vacuum duty of a pilot vacuum emulsifier and gives the vessel mechanical stability in repeated batch work. The three-tank layout also shapes batch control. With a 50L unit, you can prepare up to 40L of water phase and 20L of oil phase before transferring them into the main emulsifying vessel. With a 100L unit, those prep tanks rise to 80L and 40L. That matters when you are trying to keep phase addition smooth, avoid manual pouring, and reproduce the same temperature and mixing sequence from batch to batch. If your oil phase is 25L, for example, the 50L system is already outside its prep capacity, while the 100L system still has room for a controlled transfer. Wall thickness and tank volume therefore work together: one protects the process, and the other decides how much phase material you can prepare in one clean sequence. For cosmetic, ointment, or fine chemical pilot work, hygiene and documentation often follow GMP principles. Public WHO and FDA CFR 21 guidance is a useful reference when you define your own acceptance criteria.
How Heating, Control, and Site Power Shape the Final Configuration
Heating is usually the first option that turns a standard pilot vacuum emulsifier into a site-specific machine. The PMK-A 50L and 100L models can be configured with no jacket and no heating, an electric heating jacket, or a steam heating jacket. Electric heating is often practical for pilot plants that do not have a steam loop, because it keeps the installation inside the machine's own electrical scope. Steam heating is a natural choice when the plant already has a stable steam supply and wants to use a jacketed vessel for temperature control. Neither choice changes the confirmed capacity or motor facts, but both affect how the machine connects to your building services, so confirm the heating method before the electrical drawings are fixed. Control and site power belong in the same conversation. The machine can be supplied with PLC and touchscreen automatic control, pneumatic automatic control, semi-automatic button panels, manual control, explosion-proof control, and remote monitoring or smart networking options. The default electrical basis is AC 380V/50Hz three-phase five-wire, and the platform supports other common industrial voltages such as 400V, 415V, and 480V three-phase, along with other listed configurations. The site voltage, control level, and heating source is worth checking before electrical drawings are finalized. Your actual site voltage, wiring system, breaker capacity, and earthing arrangement is worth checking before production. The base choice is also part of the site plan. A fixed bracket, a fixed base with weighing system and adjustable leveling feet, or a movable base with casters will change how the unit fits into your pilot room and how you move it between work areas. When these details are clear, the 50L versus 100L decision becomes a real configuration instead of a guess.
Conclusion
Choose a 50L or 100L pilot vacuum emulsifier by working from the batch, not the brochure. Match the required batch volume to the main vessel and the water and oil phase tanks, then check whether your formula's viscosity calls for the 18kW motor set or the 31kW motor set. After that, lock the heating method, control package, voltage, and base style against the real pilot room. For the PMK-A 50L and 100L hydraulic lifting vacuum emulsifier, the confirmed specifications give you a clear starting point: three-tank preparation, 4/3/3 mm wall construction, and a modular build that can be configured for electric or steam heating, PLC or manual control, and fixed or movable bases.

FAQ
Q：How do I choose between a 50L and 100L pilot vacuum emulsifier?
A：Choose the 50L vacuum emulsifier when your pilot batches are smaller, your formula is expensive, or your site has limited power and space. Choose the 100L vacuum emulsifier when you need more product for stability or filling trials, or when your water and oil phase volumes exceed the 40L and 20L prep tanks on the 50L unit. The deciding factors are required batch size, phase tank capacity, viscosity, total installed power, and the utilities available in your pilot plant.
Q：What total installed power is required for a 100L pilot vacuum emulsifier?
A：The PMK-100L has a total installed power of 31kW. That covers the larger 1.5kW main agitator, 0.55kW wall scraper, 4.0kW homogenizer motor, 1.1kW hydraulic lift pump, and the rest of the installed machine load. Plan the electrical supply, breaker capacity, and wiring for a 100L pilot vacuum emulsifier around 31kW, then confirm the final voltage and connection details for your site before installation.
Q：Should I choose electric or steam heating for a pilot vacuum emulsifier?
A：Choose electric heating when your pilot plant does not have a steam supply, when you want a simpler self-contained heating setup, or when the batch size is small and controlled. Choose steam heating when your building already has a stable steam loop and you want to use a jacketed vessel for temperature control. Both are available on the PMK-A 50L and 100L models, so the right choice depends on your site utilities, temperature targets, and control preferences.
