Homogenizer

Homogenizer is a kind of equipment for homogenization/emulsification of liquid materials (liquid-liquid phase or liquid-solid phase) with viscosity below 0.2Pa.s and temperature below 80 °C. Mainly used in food or chemical industry. Industry, such as: homogenization and emulsification processes in the production process of dairy products, beverages, cosmetics, pharmaceuticals and other products.

Application of homogenizer in food processing: Homogenizer in food processing means that the material is refined under the triple action of extrusion, strong impact and pressure loss expansion, so that the material can be more uniform. Mixed with each other, such as the use of homogenizers in the processing of dairy products to make the fat in the milk broken more compact, so that the entire product system is more stable. Milk will look whiter. Homogenization is mainly carried out by a homogenizer. It is an important processing equipment for the food, dairy and beverage industries.

Homogenizer working principle:

The precision fit of the rotor and the stator, the working head (manufactured by the rotor and stator forgings), the claw structure, two-way suction, high shear efficiency.

Intermittent high-shear dispersion emulsifier homogenizer is a high-speed, strong circumferential tangential speed, angular velocity and other comprehensive kinetic energy through high-speed and stable rotation of the rotor.

Effectiveness; under the action of the stator, a strong and reciprocating hydraulic shear, friction, centrifugal extrusion, liquid flow collision and other comprehensive effects are formed in the gaps of the stator and the rotor, and the material is reciprocated in the container. Get the product.

Homogenizer features:

·Stable operation, low noise, convenient cleaning, flexible and flexible, can be used continuously, and can be ultra-fine dispersion and emulsification of materials. It can be widely applied to emulsification, homogenization and dispersion of industrial production.

·It can make the material liquid refine and mix under the triple action of extrusion, strong impact and pressure loss expansion. This equipment is an important equipment for food, dairy, beverage and other industries.

·All kinds of dairy beverages such as milk soymilk are homogenized under high pressure, which can make the fat globules in the dairy liquid remarkably refine, and make the products easy to digest and absorb after eating, and improve the use value.

·In the production of products such as ice cream, it can improve the fineness and looseness of the liquid, so that its internal texture is obviously improved.

·It can be used in the production of emulsion, glue, juice, slurry, etc. It can prevent or reduce the score layer of the liquid and improve the appearance of the liquid, making it more vivid, more concentrated and more mellow.

Homogenizer application industry

Applied to biomedicine; food industry; daily care products; coating inks; nanomaterials; petrochemicals; printing and dyeing auxiliaries; paper industry; pesticides and fertilizers; plastics and rubber; power electronics;

Application of homogenizer in soy milk: When homogenized, soymilk is pressed out from the slit of the homogenizing valve under high pressure. The fat globules, proteins and other particles are refined by the combined action of shearing force, impact force and cavitation effect. A uniform dispersion is formed. Prevent fat from floating, protein precipitation, increase the gloss of soy milk, and improve the stability of soy milk.

The homogenization effect of soymilk is subject to homogenization pressure. The homogenization temperature and the number of homogenization factors are affected by three factors. The homogenization pressure is limited by the equipment. Soymilk production can be homogenized with a pressure of 20~30MPa. When the temperature is homogeneous, the temperature is generally controlled between 55 and 65 °C. The number of homogenizations is 1~2 times.

The homogenization process can be placed before the soymilk is sterilized. It can also be placed after sterilization. Both arrangements have their own advantages and disadvantages. The homogenization is placed before sterilization, and the sterilization process can destroy the homogenization effect to some extent. Soymilk is prone to oil lines. However, the use of this process reduces the chance of contamination after sterilization. Storage is safer. Equipment costs are relatively low. And after the homogenized soymilk enters the sterilizer, it is not easy to scale. If the homogenization is placed after sterilization, the above situation is just the opposite.

The application of the homogenizer in the raw milk: breaking the large fat globules in the milk into small fat globules under the strong mechanical action of 16.7~20.6MPa. Disperse it evenly in the milk. It can effectively prevent the fat ball from floating up. In the production of pasteurized milk. The location of the general homogenizer is in the first heat recovery section of the sterilization. In the production of indirectly heated UHT milk, the homogenizer is located prior to sterilization. In the production of directly heated UHT milk. The homogenizer is located after sterilization. Therefore, a sterile homogenizer should be used. Homogenization not only prevents the fat globule from floating, but also has other advantages: the homogenized cow's milk fat globule is reduced in diameter and easily digested and absorbed by the human body. Homogenization softens the milk protein clot. Promote digestion and absorption. In the production of enzyme cheese, homogenization can accelerate the coagulation of milk, and the flavor of dairy products is more consistent.

Preheating is required before homogenization. It reaches 60~65°C, and the homogenization method generally adopts two-stage type, that is, the first stage homogenization uses a higher pressure (16.7~20.6MPa), the purpose is to break the fat globule, and the second stage homogenization uses low pressure (3.4~4.9 MPa), the purpose is to disperse the broken small fat globules and prevent adhesion.

Application of homogenizer in citrus juice: After the citrus juice is separated by centrifugation, the pulp particles are quite uniform. In order to further refine the particles. After centrifugation, homogenization can be carried out with a homogenizer at a pressure of 20 to 35 MPa.

Application of homogenizer in peach fruit juice beverage: using homogenization pressure of 25~35MPa. Enhance the affinity of pectin and juice, and at the same time improve the stability of juice, reduce the particle size and density difference between the particles, prevent the stratified sedimentation of the slurry, and make the tissue evenly viscous and the taste is fine.

How to buy:

1. Minimum test consumption: the smaller the better, the material can be saved. At present, the raw materials of some medicines reach several thousand yuan / gram, and users of course hope to complete a homogenization experiment with a minimum of materials. Moreover, the experiment is a process of repeated iterations. The minimum amount of sample is, the more materials are wasted.

2. Homogeneous pressure: not the higher the pressure, the better. For general materials, first of all: in a sense, the higher the pressure, the smaller the particle size of the material can be processed; secondly, the higher the pressure, the more types of materials that can be processed, for example, certain liquids Emulsions can only be homogenized to below 100 nm at 15,000 psi, while some pharmaceuticals, foods, especially suspensions with a certain amount of solid particles in the liquid, can be nanoscale at a pressure of at least 26,000 psi. However, some materials are not excluded from cohesion under high pressure.

3. Processing effect: The user is of course the material that he hopes to make. One is the degree of nanometer level, and the other is nanometer level. The distribution is very uniform, instead of some particles are already dozens of nanometers, and some are still Micron.

In order to solve this problem, it is recommended that the user purchase a homogenizer, and the manufacturer is equipped with a nano-scale filter extruder device, preferably an in-line extruder, which is troublesome to extrude offline.

4. Cleaning and sterilization: The imported high-pressure homogenizer is convenient for cleaning and sterilization. It is recommended to consider cleaning and sterilization online.

5. Do not consider the noise, safety, and the number of users in China. From the user list, you can determine whether a device is selling well. The more well-known users, the better the quality of this device.

6. Manufacturers of homogenizers generally say that their equipment is very good. It is recommended that they provide a list of users and provide them with relevant results and papers.

Through the above aspects, we can compare the various aspects of the high-pressure homogenizer equipment, so that we can decide which equipment we need most.
