Product Details

Product Introduction

A laboratory vacuum emulsifier is primarily used to uniformly disperse one or more phases into a continuous phase under vacuum conditions. By harnessing the powerful kinetic energy generated by mechanical action, the material is subjected to hundreds of thousands of hydraulic shear cycles per minute within the narrow gap between the stator and rotor. Through a combination of centrifugal forces, extrusion, impact, and shear, the mixture is instantaneously and evenly dispersed and emulsified. After repeated high‑frequency cycling, the final product is free of air bubbles, finely textured, and highly stable.

Working principle

After being preliminarily mixed and dispersed in the pre‑treatment tank through heating and stirring, the material is drawn into the emulsification tank by the negative pressure generated by a vacuum pump. Inside the emulsification tank, the material undergoes a complex, integrated process involving scraping‑type agitation and high‑shear homogenization, experiencing stirring, shearing, impact, and compression. This rapidly breaks the material down into micro‑droplets ranging from 200 nm to 2 µm, thereby forming a stable emulsion. During this process, the wall‑scraping blades made of polytetrafluoroethylene remain in close contact with the tank wall, swiftly removing adhering material and continuously renewing the interface between the product and the vessel wall. This not only enhances heat‑transfer efficiency but also ensures the uniformity of highly viscous materials within the tank. Meanwhile, the equipment’s high‑vacuum system rapidly evacuates entrapped air during preparation, preventing oxidation or contamination caused by bubbles in the final product; additionally, the defoamed material exhibits improved gloss and ductility.

Product Structure

The laboratory vacuum emulsifier consists of an emulsification pot (with a liftable lid and a tilting pot body), a water-phase pot, an oil-phase pot, a vacuum system, a heating and temperature-control system, a cooling system, and an electrical control system.

Product Features

1. The emulsification pot lid of the high-shear vacuum homogenizing emulsifier is automatically liftable and lowerable, and the main vessel can be tipped over for dumping.
2. The emulsification tank is equipped with a high-shear homogenizer and a counter-rotating wall-scraping agitator.
3. Equipped with two pre-processing tanks: an aqueous-phase tank and an oil-phase tank.
4. The pre-treatment tank is equipped with a high-speed dispersion system.
5. Equipped with a vacuum system, the material in the pre‑treatment tank can be drawn into the emulsification tank via a suction line under negative pressure.
6. The inner surface of the emulsification tank is mirror-polished, meeting hygienic-grade requirements.
7. The system employs a sandwich-type electric heating method, ensuring uniform heat transfer and high temperature control accuracy; it can also be connected to cooling water or coolant for cooling.
8. It employs push-button or PLC control, which is simple, intuitive, and easy to operate.
