Scaling Processes from Lab to Plant with a 50L Vacuum Emulsifier

Scaling Processes from Lab to Plant with a 50L Vacuum Emulsifier

Why correct scale-up matters for emulsion mixer applications

Moving a formulation from a bench-top recipe to a commercial batch is more than increasing volumes. Emulsion quality (stability, droplet size distribution, viscosity), process repeatability, compliance and cost all depend on how you scale mixing, shear and heat transfer. An appropriate emulsion mixer at pilot scale bridges R&D and full production—reducing risk and shortening time-to-market. The 50L Hydraulic Lift Vacuum Emulsifier is a common pilot-scale solution designed to replicate plant conditions while remaining manageable for iterative development.

Common challenges when scaling emulsions (and how the right emulsion mixer helps)

Typical scale-up hurdles include: droplet size shift, phase inversion, inadequate heat transfer, foaming and entrapped air, and inconsistent powder incorporation. These issues arise because geometry, shear fields and residence time change nonlinearly with volume. A properly designed vacuum homogenizer/emulsion mixer helps by providing controlled shear via a homogenizing rotor-stator, precise vacuum degassing to eliminate entrained air, repeatable heating/cooling jackets for thermal control, and robust powder absorption systems to incorporate solids without clumps.

Introducing the 50L Hydraulic Lift Vacuum Emulsifier

50L Hydraulic Lift Vacuum Emulsifier — Product Overview

Yuanyang hydraulic lift vacuum emulsifier is a combined mixing equipment with a main vacuum homogenizer tank, a water tank, and an oil tank, which is an integrated equipment with a mixing, dispersing, homogenizing, emulsifying, vacuumizing and powder absorption system that is widely used in cosmetics, food, pharmaceutical, and chemical fields.

Features:

⦁ With a hydraulic lift lid & tilting pot, vacuum system, and electric control system.

⦁ Suitable for products of 10,000~50,000 cps viscosity.

⦁ Perfect particle size of 2 microns and evenly distributed.

Key design elements of this emulsion mixer and why they matter

The 50L Hydraulic Lift Vacuum Emulsifier integrates three key systems: (1) a vacuum homogenizer tank for degassing and high-shear homogenization, (2) separate water and oil tanks for controlled pre-heating and phased addition, and (3) a powder absorption and mixing system for easy incorporation of solids. Important benefits include hydraulic lift and tilting for safe loading/unloading, electric control for repeatable recipes, and the capability to handle viscosities commonly found in creams, ointments and high-viscosity sauces (10,000–50,000 cps). The emulsifier's homogenizer can achieve particle sizes down to 2 microns—critical for stable, aesthetic emulsions.

Process parameters to monitor and control with the 50L emulsion mixer

Successful scale-up requires active control of these variables:

• Shear rate / rotor speed — Dictates droplet breakup. Keep rotor/stator geometry and tip speed consistent with lab trials when possible.
• Temperature profile — Heating rate and hold time affect solubility and emulsifier activation.
• Vacuum level — Reduces entrained air and boiling point for volatile components; improves stability and aesthetic.
• Addition order & rate — Oil phase addition speed into water phase, and powder feed rates influence droplet formation and lumping.
• Residence time — Time inside homogenizer under target shear; too short yields coarse emulsions, too long may overwork sensitive actives.

The 50L emulsifier's controls allow operators to set and log these variables, enabling reproducible transfer of lab procedures to pilot batches.

Step-by-step scale-up strategy using the 50L Hydraulic Lift Vacuum Emulsifier

1. Characterize the lab process

Document lab conditions precisely: stirrer geometry, rpm, temperature ramps, vacuum used, order of addition, and measured properties such as droplet size distribution (D50), viscosity, pH, and stability data. These will be the baseline for scaling decisions.

2. Map geometric and dynamic similarity where possible

Complete geometric similarity is rarely possible, but maintain key dimensionless numbers when practical: Reynolds number (flow regime), tip speed for rotor-stator systems, and energy input per unit volume (kW/m3). The 50L unit's rotor-stator design allows matching tip speeds to preserve shear conditions encountered in lab homogenizers.

3. Conduct pilot batches with incremental increases

Start with small pilot runs on the 50L unit using the documented lab recipe. Monitor critical quality attributes (CQA) — droplet size, viscosity, pH, and stability. Adjust rotor speed, vacuum, addition rates and hold times as needed. Record adjustments and rationale for reproducibility.

4. Validate process windows

Use the 50L to map a robust operating range: upper/lower limits for rotor speed, temperature and vacuum that still produce acceptable CQAs. This creates the basis for transfer to larger plant emulsifiers and for regulatory documentation.

5. Create scale-up specification and SOPs

Document exact setpoints, equipment configuration, start-up/shut-down procedures, cleaning steps (CIP/SIP if applicable), and batch records. The hydraulic lift and tilting pot features on the 50L simplify cleaning and material handling, which should be reflected in SOPs.

Yuanyang brand advantages when scaling emulsions

When you select the 50L Hydraulic Lift Vacuum Emulsifier from Yuanyang you gain:

• Integrated pilot features designed to reflect plant operations—separate oil/water tanks, powder feed, vacuum homogenizing tank—so scale-up is more predictable.
• User-friendly ergonomics—hydraulic lift and tilting pot simplify material handling and cleaning.
• Proven performance—ability to reach 2 µm particle size and handle 10,000–50,000 cps viscosity increases the range of formulations you can validate.
• Comprehensive electrical and vacuum controls for recipe repeatability and easier tech transfer documentation.

Frequently Asked Questions (FAQ)

Q1: Can the 50L Hydraulic Lift Vacuum Emulsifier reproduce lab droplet size distributions?

A: In most cases yes, if rotor tip speed, energy per unit volume and thermal history are matched. Expect small shifts in D50; use the 50L for iterative adjustments until the target distribution and stability are met.

Q2: What product viscosities can it handle?

A: The unit is suitable for products between 10,000 and 50,000 cps. For products outside this range, consult engineers to verify pumpability and seal compatibility.

Q3: How does vacuum improve emulsions?

A: Vacuum reduces entrained air and prevents micro-foam, improving visual quality and stability. It also lowers boiling points for volatile components, which must be managed to avoid component loss.

Q4: Is the 50L suitable for pharmaceutical GMP production?

A: The 50L is often used for pilot and development work supporting GMP manufacturing. For GMP production, ensure the final configuration, materials, documentation, and cleaning validation meet regulatory requirements.

Q5: What analytical controls are recommended during scale-up?

A: Recommended controls include droplet size distribution (laser diffraction), viscosity profiling, pH, thermal profile logs, and stability (accelerated and real-time). Track these during pilot runs to define acceptable process windows.
