Introduction of homogenizer

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

The application of homogenizer in food processing: The homogenizer in food processing refers to refining the material under the triple action of extrusion, strong impact and pressure loss expansion, so that the material can be more uniform. Mixing with each other, such as the use of a homogenizer in the processing of dairy products, makes the fat in the milk break up more finely, 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 in the food, dairy and beverage industries.

The working principle of the homogenizer:

The precise coordination of the rotor and the stator, the claw structure of the working head (manufactured by the rotor and the stator forging), the bidirectional suction, and the high shearing efficiency.

Intermittent high shear dispersing emulsification homogenizer is through the high-speed and stable rotation of the rotor to form high-frequency, strong circumferential tangential velocity, angular velocity and other comprehensive kinetic energy

Efficiency; under the action of the stator, a strong, reciprocating hydraulic shear, friction, centrifugal extrusion, liquid collision and other comprehensive effects are formed in the reasonably narrow gap between the stator and the rotor, and the material circulates and reciprocates in the container. get product.

Homogenizer Features:

·Stable operation, low noise, convenient cleaning, flexible maneuverability, continuous use, and ultra-fine dispersion and emulsification of materials. It can be widely used in emulsification, homogenization and dispersion in industrial production.

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

·For various dairy beverages such as milk and soy milk, homogenizing under high pressure can significantly refine the fat globules in the milk liquid, making the products easy to digest and absorb after eating, and improving the use value.

·Used in the production of ice cream and other products, it can improve the fineness and looseness of the material and liquid, so that the internal texture is significantly improved.

·Used in the production of emulsions, glues, juices and slurries, etc., it can prevent or reduce the splitting of the material liquid, improve the appearance of the material liquid, and make it more bright in color, stronger in aroma and more mellow in taste.

The application industry of the homogenizer

Used in biomedicine; food industry; daily chemical care products; paint and ink; nanomaterials; petrochemical industry; printing and dyeing auxiliaries; paper industry; pesticides and fertilizers; plastics and rubber; power electronics; other fine chemical industries.

Application of homogenizer in soymilk: Soymilk is pressed out from the slit of the homogenizer valve under high pressure during homogenization. Under the combined action of shear force, impact force and cavitation effect, particles such as fat globules and proteins in a constant temperature homogenizer are miniaturized. A homogeneous dispersion is formed. Prevent fat from floating, protein precipitation, increase the gloss of soymilk, and improve the stability of soymilk.

The homogenization effect of soymilk is affected by homogenization pressure. Three factors affect the homogenization temperature and the number of homogenization times. Homogenization pressure is limited by equipment. In the production of soymilk, the pressure of 20~30MPa can be used for homogenization. It is more suitable to control the temperature between 55~65℃ during homogenization. Homogenization times 1 to 2 times.

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

The application of homogenizer in raw milk: under the action of strong mechanical force 16.7~20.6MPa, the large fat globules in the milk are broken into small fat globules. Disperse evenly in the milk. It can effectively prevent fat globules from floating. in the production of pasteurized milk. Generally, the location of the homogenizer is in the first heat recovery section of sterilization. In indirect heated UHT milk production, the homogenizer is located before the sterilization. In direct heated UHT milk production. The homogenizer is located after sterilization. Therefore a sterile homogenizer should be used. Homogenization can not only prevent the fat globules from floating, but also has some other advantages: the diameter of the milk fat globules after homogenization is reduced, which is easy to be digested and absorbed by the human body. Homogenization softens the milk protein curd. Promote digestion and absorption. In the production of enzymatic cheese, homogenization can accelerate the coagulation of milk and make the flavor of dairy products more consistent.

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

The application of homogenizer in citrus juice: After the citrus juice is centrifuged, the pulp particles are quite homogenized. In order to further refine the particles. After centrifugation, a homogenizer can be used to homogenize with a pressure of 20~35MPa.

The application of the homogenizer in the peach pulp juice beverage: the homogenization pressure of 25~35MPa is adopted. It can enhance the affinity between pectin and fruit juice, improve the stability of fruit juice, reduce the particle size and density difference between particles, prevent the stratification and precipitation of the slurry, and make the tissue uniform and viscous, and the taste is delicate.

How to buy:

1. Minimum trial amount: the smaller the better, which can save materials. At present, the raw materials of some medicines reach several thousand yuan/gram. Of course, users hope that a homogenization experiment can be completed with the least amount of materials. Moreover, the experiment is a repeated process, the larger the minimum sample size, the more material wasted.

2. Homogeneous pressure: It is not that the higher the pressure, the better. For general materials, first: 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, some liquids Emulsions only need to be homogenized to below 100 nm at 15,000 psi, while some medicines, foods, especially suspensions with a certain amount of solid particles in liquids, require at least 26,000 psi to achieve nano-scale. However, it is not excluded that some materials coagulate under high pressure.

3. Processing effect: Of course, the user wants to make the material. One is that it can reach the level of nanometers, and the other is that the distribution of nanometers is very uniform, not that some particles are already dozens of nanometers, and some are still micron scale.

In order to solve this problem, it is recommended that when purchasing a homogenizer, the user should ask the manufacturer to equip it with a nano-level filter extruder device, preferably an online extruder, which is very troublesome to extrude offline.

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

5. It is inevitable to consider the noise, safety, and number of users of a device 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 the device.

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

Through the inspection of the above-mentioned aspects, we can compare many aspects of the high-pressure homogenizer equipment, so as to decide which equipment you need the most.
