Case Studies: Products Made with 50L Vacuum Emulsifiers

Introduction — emulsifying machine and product overview

Small-to-medium batch production and R&D labs increasingly depend on a robust emulsifying machine for repeatable, high-quality results. The 50L Hydraulic Lift Vacuum Emulsifier offers a compact, flexible solution that combines mixing, dispersing, homogenizing, emulsifying, vacuumizing and powder absorption in one integrated unit. Below is the official product introduction for reference:

Yuanyang hydraulic lift vacuum emuslifier 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.

This article uses multiple case studies to show how a 50L Hydraulic Lift Vacuum Emulsifier (emulsifying machine) is applied across industries, the technical benefits it brings, operational best practices, and how it compares to other mixing technologies.

Case Study 1 — Cosmetic Cream: achieving stable, luxurious textures with the emulsifying machine

Challenge: A mid-size cosmetics startup wanted to scale up a High Quality face cream formula from 5 L lab batches to 30–45 L pilot batches without losing the silky feel and stability achieved at lab scale. The key success metrics were droplet size (target <2.5 μm), viscosity stability (20,000–35,000 cps), and no phase separation after 6 months.

Process and settings (50L Hydraulic Lift Vacuum Emulsifier):

• Preheat water and oil phases separately to 70°C in dedicated tanks.
• Use low-speed anchor agitator for bulk heating and degassing.
• Introduce oil phase into main tank while vacuum draws air out to prevent oxidation.
• Start rotor-stator homogenizer at medium speed, then apply high-shear homogenization for 5–8 minutes to achieve target droplet size.
• Cool under vacuum to 40°C while continuing gentle homogenization for texture refinement.

Results: The emulsifying machine consistently produced creams with mean droplet size near 1.8–2.0 μm, excellent sensory feel, and stability over 12 months in accelerated aging tests. The hydraulic lift lid and tilting pot allowed safe loading/unloading and easier cleaning, reducing downtime between batches.

Case Study 2 — Pharmaceutical Ointment: contamination control and controlled viscosity

Challenge: A small pharmaceutical manufacturer developing a topical ointment needed strict vacuum processing to minimize air inclusion and microbial contamination risk during emulsion formation. Desired viscosity range: 15,000–40,000 cps. Accuracy and recordability of process parameters were required for regulatory compliance.

Process notes:

• Use the unit’s vacuum system to achieve <50 mbar during homogenization to remove dissolved gases and avoid air pockets.
• The integrated electric control system recorded process profiles (temperature, vacuum, homogenizer speed) for traceability.
• Sanitary design and CIP (clean-in-place) compatible pot minimized cross-contamination risk.

Results: The 50L emulsifying machine met pharmaceutical cleanliness and process traceability needs. Ointments showed uniformity and required spreadability; batch-to-batch viscosity variance was <5%. The vacuum environment also reduced oxidation of sensitive actives, improving shelf-life.

Case Study 3 — Food Spread (Sauce): improving mouthfeel and shelf stability

Challenge: Developing a High Quality sauce/spread with high oil content and smooth mouthfeel, avoiding oil separation during storage. Food-grade materials and gentle processing to protect volatile flavors were important.

Approach:

• Use the oil tank for controlled oil dosing and the water tank for aqueous phase preparation.
• Apply vacuum emulsification to limit entrained air (reduces oxidation) and preserve flavor.
• Target particle size around 2 μm for stable emulsion and desirable texture.

Outcome: The emulsifying machine produced a sauce with superior creaminess and no phase separation after 3 months at ambient conditions. The vacuum processing reduced foaming and retained volatile flavor compounds, enhancing sensory acceptance.

Why choose the 50L Hydraulic Lift Vacuum Emulsifier for R&D and small production?

For manufacturers evaluating an emulsifying machine, the 50L Hydraulic Lift Vacuum Emulsifier hits a sweet spot between lab-scale flexibility and production-level repeatability. Key advantages that address buyer intent:

• Capacity fit: 50 L is practical for pilot batches, small production runs and formulations needing scale-up verification.
• Integrated systems: having a main homogenizer tank plus dedicated water and oil tanks simplifies workflow and reduces transfer contamination.
• Hydraulic lift lid & tilting pot: improves ergonomics and safety for loading, sampling and discharge.
• Vacuum capability: essential for removing air, preventing oxidation and improving product density and appearance.
• Electric control system: supports repeatable recipes and quality control through process parameter logging.
• Viscosity range (10,000–50,000 cps): covers a wide variety of cosmetics, ointments and viscous foods.

Below is a compact comparison table to help decision-makers evaluate technologies for emulsion production.

Operation and maintenance tips for the emulsifying machine (industrial mixer)

To ensure long-term performance from a 50L vacuum emulsifier, follow these practical recommendations:

• Preheat phases evenly — temperature mismatches cause poor emulsification and larger droplet sizes.
• Maintain the vacuum system — check seals, gauges and vacuum pumps regularly to sustain degassing performance.
• Record process parameters — use the electric control system to log temperature, RPM and vacuum for reproducibility and troubleshooting.
• Schedule rotor/stator inspections — replace worn rotor or stator parts before they cause excessive heat or poor shear.
• Use proper CIP/SIP routines — validated cleaning cycles prevent cross-contamination, especially for pharma and food.
• Train operators on pot tilting and hydraulic lift safety — hydraulic failure or misuse can cause spills and injuries.

Performance metrics and measurable benefits

Manufacturers who adopt the 50L Hydraulic Lift Vacuum Emulsifier typically observe these measurable improvements:

• Reduced bubble entrainment by 40–80% thanks to vacuum processing (varies by formula).
• Smaller and more uniform droplet sizes (target 1.5–2.5 μm), improving stability and gloss in cosmetic products.
• Lower oxidation of sensitive ingredients leading to longer shelf life and better color retention.
• Faster batch turnaround due to integrated water/oil tanks and hydraulic features, reducing manual transfers.
