Inline Powder Liquid Mixer

What is the inline powder liquid mixer? We will have a specific introduction to the structural principles, operating modes, equipment configurations, and typical applications of this type mixer(the device in the following video) here. Integrating powder-liquid mixing, circulation homogenization, and high-shear emulsification, it is an ideal choice for the production of liquid emulsions such as food pastes, cosmetic lotions, and pharmaceutical creams.

I. Product Overview

The inline powder-liquid mixer is an in-line emulsification device specifically designed for the mixing and homogenization of powders and liquids. As the name suggests, it employs an inline structure wherein materials flow continuously through a closed piping system. Powder-liquid mixing and homogenization are achieved through the high-shear action generated by the emulsification pump.

II. Equipment Structure

This mixer primarily consists of a feed hopper, an emulsification pump, circulation piping, discharge piping, and control valves.

III. Working Principle

What is the working principle behind this equipment? Its operational core lies in the precise coordination between the emulsification pump's high shear homogenizing function and the system's pipeline circulation capabilities. This ensures that powdered and liquid materials undergo continuous circulation and homogenization. Thereby the mixer can meet the specific fineness requirements of various clients. For a detailed understanding, please refer to the equipment's workflow description below.

Step 1: Feeding

• Powdered and liquid materials are introduced via the hopper.

• The two types of materials make initial contact within the hopper.

Step 2: Emulsification and Homogenization

• The materials enter the emulsification pump.

• They undergo high-shear, dispersion, and emulsification processes facilitated by the pump's stator and rotor components.

• The powdered material is uniformly dispersed throughout the liquid phase.

Step 3: Circulation Processing

• The homogenized material returns to the hopper via the circulation pipeline.

• It re-enters the emulsification pump for a secondary round of processing.

• The number of circulation cycles determines the final fineness of the emulsion.

Step 4: Discharge (Upon Meeting Specifications)

• The operator can monitor the emulsification status at any time.

• Once the required specifications are met, the circulation valve is closed, and the discharge valve is opened.

• The finished product is discharged, marking the completion of the batch.

IV. Equipment Application

This inline mixer—also referred to as an inline emulsifier—is a highly versatile piece of equipment suitable for widespread application across the food, cosmetics, and pharmaceutical industries, among others.

4.1 Primary Application Fields

4.2 Applicable Product Forms

• Liquid Emulsions

• Cream-based Products

• Emulsion Systems (Oil-in-Water / Water-in-Oil)

• Powder-Liquid Suspensions

V. Design Advantages

To ensure the equipment's long-term durability, our design incorporates a water-cooling protection system and a mechanical seal mechanism.

5.1 Water-Cooling Protection - Preventing Overheating Damage

Why is water cooling necessary? When an emulsification pump operates at high speeds, it generates a significant amount of heat. Without effective cooling, the following issues may arise:

• Aging and damage to sealing components

• Thermal deformation of the stator and rotor

• Overheating and degradation of the processed materials

• Reduced service life of the equipment

The water-cooling system dissipates heat through the circulation of cooling water, thereby ensuring the equipment operates stably even at high rotational speeds.

5.2 Mechanical Seal Design - Preventing Leakage

VI. Equipment Configuration Schemes

For this device, there are primarily three types of configuration forms as show in the above picture. You can see the specific explanations of the three types as followed:

1)Configuration 1: Standard Model (Independent Feeding Head Design)

2)Configuration 2: Upgraded Model (Paired with Mixing Tank)

3)Configuration 3: High-Viscosity Model (Paired with Rotor Pump)

VII. Summary

Briefly, the inline powder liquid mixer employs a circulating homogenization mode of operation. Materials undergo repeated processing within the high-shear stator-rotor assembly of the emulsification pump. Combined with water-cooling protection and a mechanical seal design, this system achieves highly efficient mixing and homogenized emulsification of powders and liquids.
