What Is a Vacuum Homogenizer Emulsifier Mixer? A Complete Guide for Mayonnaise and Cosmetic Production

A vacuum homogenizer emulsifier mixer is a specialized processing machine used to create stable emulsions, dispersions, and mixtures under controlled vacuum conditions. YeKeey (Wuxi YK Automation Technology Co., Ltd.), a Chinese manufacturer established in 1998, produces a range of vacuum emulsifying mixers designed for the food, cosmetics, and daily chemical industries. This guide explains what these machines are, how they work, and why they are essential for products like mayonnaise and cosmetic creams.

The Problem: Inconsistent Emulsions and Air Entrapment

Traditional mixing methods often struggle to achieve the fine, stable emulsion required for high-quality mayonnaise, salad dressings, creams, and lotions. Air bubbles trapped during mixing can cause oxidation, shorter shelf life, and an undesirable texture. Without vacuum capability, it is difficult to remove air from the mixture, leading to product inconsistencies. Manufacturers need a solution that can both emulsify and deaerate simultaneously.

Industry Background: Growing Demand for Vacuum Emulsification

The global homogenizers market was valued at approximately USD 2.10 billion in 2024 and is projected to reach USD 3.79 billion by 2035 (Roots Analysis). Within this space, the vacuum mixer homogenizer segment was estimated at USD 1.02 billion in 2026, with the cosmetics and personal care segment holding a 38% market share (Future Market Insights). The mayonnaise market alone was worth around USD 12.58 billion in 2024 (Zion Market Research), further driving the need for efficient vacuum emulsification equipment. Asia-Pacific dominates the homogenizing mixer market with a 36.2% revenue share as of 2025, largely due to China's manufacturing ecosystem (Dataintelo).

Detailed Solution: YeKeey Vacuum Homogenizer Emulsifier Mixer

YeKeey's Vacuum Emulsifying Mixer is a purpose-built machine that performs emulsifying, homogenizing, mixing, and dispersing functions. It operates under vacuum conditions with a pressure range of -0.09 MPa and is designed for high-temperature environments up to 110°C. The mixer is constructed from stainless steel grades SS304 or SS316, ensuring corrosion resistance and compliance with food-grade and cosmetic-grade standards. It can be controlled via button control or PLC system, and it supports integration with auxiliary ducting systems.

YeKeey offers three main series of vacuum emulsifying mixers:

• MC Series (Recirculation Homogenizing Mixer) – Available in models MC-100 to MC-2500, with power range 5–91.5 kW and output speed up to 2800 rpm. Suitable for both laboratory and production scale.
• ZJR Series (Vacuum Emulsifying Mixer) – Model range from ZJR-5 to ZJR-2500, power 5–91.5 kW, output speed 2800–6000 rpm. Includes a lab version (ZJR-Lab).
• SP Series (Standard Vacuum Processing Unit) – Models SPA-30 to SPA-10T, power 3.7–110 kW, output speed up to 2800 rpm. Offers larger capacity options up to 10 tons.

Step-by-Step Operation

1. Material Loading – Raw materials (oil, water, emulsifiers, active ingredients) are introduced into the main vessel through a feeding port.
2. Vacuum Generation – The system draws a vacuum of -0.09 MPa to remove air and prevent foam formation.
3. High-Shear Homogenization – A rotor-stator assembly rotates at up to 6000 rpm (depending on model), creating intense shear forces that break droplets into micron-sized particles.
4. Mixing and Heating – Anchor or scraper blades continuously mix the batch while a heating jacket maintains temperatures up to 110°C.
5. Cooling and Discharge – After the desired emulsion is achieved, the batch is cooled and discharged through a bottom valve.

Use Cases

Mayonnaise Production

In mayonnaise manufacturing, the vacuum homogenizer emulsifier mixer ensures a fine, stable oil-in-water emulsion without air bubbles. The high-shear rotor-stator homogenizes egg yolk, oil, vinegar, and seasonings into a smooth, creamy texture. The vacuum prevents oxidation, extending shelf life. YeKeey's equipment is applied in food sauce sector projects globally.

Cosmetic Cream and Lotion Manufacturing

For skincare products such as creams, lotions, and serums, the mixer emulsifies water and oil phases into a uniform product. The vacuum deaeration eliminates micro-bubbles that can cause surface defects. YeKeey's vacuum emulsifying mixers are used in cosmetic manufacturing lines and personal care product production lines, handling high-viscosity formulations with ease.

Daily Chemical Products

Shampoos, conditioners, and liquid detergents also benefit from vacuum emulsification to achieve desired consistency and clarity. The SP series offers large volume options (up to 10,000 liters) for bulk production.
