What Is A Mixing Reactor

Mixing reactor is a kind of equipment for chemical reaction, which can carry out multiple reactions simultaneously in the same container. This kettle usually consists of a main container and one or more auxiliary devices, which can be mixed, heated, cooled and stirred under controlled conditions.

The mixing equipment premise is to employ diverse reactants to carry out a mixing reaction at a specific temperature, pressure, and duration to create the needed chemical reaction. It can be utilized in a variety of chemical reactions, including organic synthesis, polymerization, hydrolysis, and redox reactions.

The Structure

 

Main container: The main container is the main place for reaction, which is usually made of corrosion-resistant materials (such as stainless steel) and has sufficient strength and sealing performance. The main vessel usually has an appropriate volume and shape to meet the reaction requirements.

 

Accessories: Accessories include stirring device, heating device, cooling device, feed inlet, discharge outlet, etc. Stirring device usually consists of agitator and driving device, which is used to mix reactants and promote the reaction. The heating device can provide heat by conduction, heat transfer oil or steam, while the cooling device can reduce the reaction temperature by circulating coolant (such as cold water or cold air).

 

Control system: The mixer reactor is usually equipped with a control system to monitor and adjust the reaction conditions, such as temperature, pressure and stirring speed. This enables operators to monitor the progress of the reaction in real time and make corresponding adjustments as needed.

MIXING

Common Types of Mixing Reactors

Batch mixing reactor: Batch mixing reactor machine is the most common type, which is suitable for small batch production or laboratory-scale reaction. In batch mixing reactor, the reaction materials are added into the reactor at one time for reaction, and the product needs to be taken out after the reaction, and the next round of reaction can only be carried out after the kettle body is cleaned.

Continuous mixing reactor: Contrary to batch reactor, continuous mixing reaction can continuously react and is suitable for large-scale production. The reaction materials are continuously added and discharged to realize the continuous reaction process.

Stainless steel mixing reactor: A mix reactor made of stainless steel has good corrosion resistance and structural strength, and is suitable for various chemical reactions, especially when the reaction medium is required.

Glass reaction kettle: Glass reaction kettle is usually used for laboratory-scale reactions, and it is suitable for some occasions where it is necessary to observe the reaction process, such as observing color changes and precipitation formation.

High-pressure reaction kettle: Used for reaction under high pressure, usually used for some chemical reactions that need high temperature and high pressure environment, such as hydrogenation reaction and synthesis reaction.

Stirred reactor: It has a stirring device, which is used to keep the reaction materials evenly mixed and promote the reaction.

Fermentation reactor: Used in microbial fermentation process, such as fermentation reaction in pharmaceutical and food industries.

Common agitator shapes

1. Anchor Agitator: An anchor agitator is an agitator with anchor blades, which is usually fixed at the bottom and extends into the reaction liquid. It is suitable for reaction materials with high viscosity or easy caking, and can effectively stir the materials deposited at the bottom.

2. Paddle Agitator: Paddle agitator has flat blades and is usually mounted on a horizontal shaft. It is suitable for reactions that do not require high stirring intensity and can provide a larger surface stirring area.

3. Helical Agitator: Helical agitator has spiral blades, which can produce propulsion and mixing effects along the axis. It is suitable for high viscosity reaction materials and can effectively stir the materials from the bottom up.

4. Conical Agitator: Conical agitator has conical or inclined blades, which can produce strong shear force and eddy current effect in the reactor. It is suitable for reactions that require high mixing strength and shear force.

5. Ribbon Agitator: Ribbon agitator has ribbon blades, which can provide high shearing force and mixing effect. It is suitable for reactions that require strong mixing and uniformity.

Sweet condensed milk is a common dairy product, which is made by mixing milk or milk powder with sugar, heating, concentrating and dewatering.

In the production of sweet condensed milk, the mixing reaction unit is mainly used in the following aspects.

Mixing reaction: The machine can fully mix milk or milk powder with sugar, and make it evenly distributed through the stirrer to ensure that sugar and dairy products are fully contacted, so as to achieve the purpose of uniform dissolution and reaction.

Heating and concentration: The mixing equipment is usually equipped with a heating device, which can heat the reaction materials and improve the reaction rate and efficiency. In the process of making sweet condensed milk, it is necessary to heat the emulsion to a certain temperature to promote the dissolution and reaction of sugar, and gradually concentrate the emulsion.

Dehydration: In the process of making sweet condensed milk, the ss mixed reactor can also be used for dehydration. By means of heating and evaporation, the water in the emulsion is gradually evaporated to concentrate the emulsion to the required concentration.

Temperature control: The mixing reactor is usually equipped with a temperature control system, which can accurately control the temperature during the reaction. In the production of sweet condensed milk, temperature control is very important, which can affect the reaction rate, product quality and taste.
