500L Stainless Steel Fixed Vacuum Homogenizer Emulsifier Mixer for Cream Making

Product Introduction

Designed Specifically for Large‑Volume Continuous Production

Looking for an emulsification system that handles high‑viscosity formulations while saving on factory ceiling height and equipment investment? Our Fixed Vacuum Homogenizing Emulsifier is purpose‑built for exactly this requirement. Unlike hydraulic lift‑type models, this machine features a fixed, non‑detachable connection between the lid and vessel, eliminating the hydraulic lifting mechanism. This design drastically reduces overall equipment height for easier installation in low‑rise workshops, while delivering a highly cost‑effective price advantage.

This machine is particularly ideal for large‑batch, single‑product continuous production. It delivers exceptional homogenization results for a wide range of products, including toiletries such as body wash and shampoo, as well as high‑viscosity formulations like creams, ointments and pastes.

Core Structure & Working Principle

The system mainly consists of a pre‑processing mixing tank (oil/water phase pot), main vacuum emulsification vessel, vacuum pump system, electrical control system and operating platform. Its workflow follows an efficient three‑step process:

1. Pre‑processing: Raw materials for the oil phase and water phase are separately heated and dissolved in their respective pre‑processing pots until reaching the set temperature.
2. Vacuum Feeding: Pre‑mixed oil and water phases are drawn directly into the sealed main vessel via negative vacuum pressure, preventing contamination and air bubble entrainment.
3. Homogenization & Blending: Materials undergo final emulsification under the combined action of high‑speed shear homogenization and low‑speed wall‑scraping agitation, ensuring uniform and stable emulsified products.

Core Advantages

• Efficient Vacuum Deaeration for Enhanced Product Texture

Operating under vacuum conditions, bubbles generated during material mixing are instantly removed. This guarantees the final products (such as creams and lotions) are glossy, fine and pore‑free, resolving issues of bubble formation, bacterial contamination and easy oxidation caused by conventional mixing.

• Bottom‑Mounted High‑Shear Homogenizer

Equipped with a powerful bottom‑mounted homogenizer featuring a stator‑rotor structure. As materials pass between the high‑speed rotating rotor and stationary stator, they undergo intense shearing, impact, crushing and turbulence, with droplet sizes refined down to 1μm or even nanoscale, ensuring a smooth, particle‑free finished product.

• PTFE Wall‑Scraping Mixing System

The unique frame‑type wall‑scraping agitator is fitted with PTFE scrapers. During mixing, the scrapers maintain close contact with the inner tank wall, continuously removing high‑viscosity materials adhering to the wall to prevent burning and caking, while improving heat exchange and ensuring full circumferential mixing with no dead zones.

• All‑In‑One Multifunctional Integration

Complete process flows including heating, cooling, vacuum degassing, emulsification, mixing and milling can be fulfilled in a single unit. The system effectively handles high‑viscosity bases and high‑solid‑content formulations (such as pigments and titanium dioxide).

• Automated Control System

Production is automated via panel or pushbutton control. A PLC touchscreen and data logging system are available as options, enabling real‑time monitoring of temperature, rotation speed and vacuum level with trend recording functionality.

FAQ

Q1: What's the difference between a fixed vacuum homogenizing emulsifier and a hydraulic lift-type model? How should I choose?

• Fixed Type: The lid is permanently fixed, resulting in a lower overall height and a more cost-effective price. It is ideal for single-product, large-batch production.
• Lift-Type: The lid can be hydraulically lifted, and the vessel can be tilted for discharge. This design enables easy cleaning and fast product changeover, making it perfect for multi-product, small-batch production.

Selection Recommendation: If your factory has limited ceiling height, or if you have a tight budget and relatively consistent product formulations, the fixed type offers the highest cost-effectiveness.

Q2: What is the maximum viscosity of materials that a vacuum emulsifier can handle?

This machine is engineered to process high-viscosity materials. Equipped with a powerful wall-scraping system and a bottom-mounted homogenizer head, it can effectively form laminar flow and material exchange for pastes with viscosities as high as hundreds of thousands of centipoise (cps), such as high-viscosity hair wax and ointments, achieving uniform mixing.

Q3: Homogenizers are available in top-mounted and bottom-mounted designs. Which one is better?

• Bottom-Mounted Homogenizer: Leverages gravity to feed materials directly into the shear head, making it ideal for large-batch production. It is currently the most mainstream and efficient solution on the market.
• Top-Mounted Homogenizer: Suited for specific formulations that require liquid sealing or are prone to sedimentation.

Our equipment is typically equipped with a bottom internal/external circulation homogenization system, ensuring that both the material at the tank bottom and throughout the vessel is thoroughly refined.
