What equipment is needed for microencapsulation production?

In today's high-tech and refined production fields, microencapsulation technology, as an advanced material processing method, is widely used in the fields of, food, cosmetics, textiles, agriculture, and many other industries. Microencapsulation can effectively protect active ingredients, control the release rate, and enhance product stability and functionality.

1. Equipment composition

The microcapsule production line usually includes the equipment for the following key processes:

Raw material preparation system Responsible for the metering, mixing, and pre-treatment of raw materials. This includes precise metering pumps, high-speed mixers, and homogenizers,., to ensure that the raw materials are uniformly and precisely mixed and blended.

Microencapsulation reaction device: The core part, used to achieve the microencaps of active substances. Common ones include spray dryers, fluidized bed coating machines, emulsification equipment, and interfacial polymerization equipment, etc. Each type of equipment varies to different microencapsulation technologies (such as physical method, chemical method, or physicochemical method).

Drying and solidification system: Used to remove moisture orvents from the microcapsule products, ensuring the stability and morphological integrity of the capsules. Common equipment includes freeze dryers, hot air dryers, and infrared dryers,.

Grading and sieving equipment: Through vibrating screens, airflow classifiers, etc., the microcapsule products are classified by particle size, and particles that too large or too small are removed to ensure the consistency of product quality.

Packaging and preservation system: The final step, using automatic packaging machines for aseptic packaging finished products, ensuring the long-term preservation and transportation safety of products.

2.Working Principle

1. Raw Material Preparation: Different raw materials are precisely weighed by weight or volume and quickly mixed evenly a high-speed mixer, providing a stable base liquid for the subsequent microencapsulation process.

2. Microencapsulation:

Spray Drying: liquid raw material is atomized into extremely fine droplets, which rapidly evaporate moisture in hot air, forming dry powder microcapsules.

Fluidized Bed Co: Solid particles are suspended by gas action and coated layer by layer with a coating material to form microcapsules. Ultrasonic Emulsification: Ultrasonic is used to generate intense local high temperatures and pressures, promoting the encapsulation of active ingredients by the wall material.

Interfacial Polymerization: A wall is generated chemical reactions at the interface of two immiscible liquids, encapsulating the core material.

3. Drying and Curing: Appropriate drying methods are selected according different process requirements, such as lyophilization, which removes moisture by sublimation, preserving the integrity of the material structure; hot air drying, on the other hand, uses energy to evaporate moisture.

4. Grading and Screening: Microcapsules are separated by size through mechanical vibration or airflow separation to ensure product quality uniformity.

5. Packaging and Storage: Automated equipment is used to package the screened qualified microcapsules under aseptic conditions, extending the shelf life and facilitating transportation.

3.Performance Characteristics

High automation:The entire production line is integrated with an automated control system, reducing human intervention and improving production and product quality stability.
