Working principle of homogenizer:
The precise matching of the rotor and stator, the claw structure of the working head (manufactured by the rotor and stator forgings), bidirectional suction, high shear efficiency.
Intermittent high-shear dispersing emulsifying homogenizer is the high-speed, strong circumferential tangential speed, angular speed and other comprehensive kinetic energy efficiency formed by the rotor rotating at high speed and smoothly; Strong, reciprocating hydraulic shear, friction, centrifugal extrusion, liquid flow collision and other comprehensive effects are formed, and the materials are circulated in the container to reciprocate the above working process to finally obtain the product.
Overview and classification of homogenizer:
With the development of biomedicine, petrochemical industry, food industry and other fields, more and more homogenizers are used. The development of the experimental instrument industry has also provided a variety of different function homogenizers for laboratories in the above industries.
The principle of the homogenizer commonly used in the laboratory: the experimental sample and the solution or solvent are mixed uniformly to reach the standard solution required by the experiment. According to the working mode of its homogenizer, it can be divided into the following three categories:
1. Ultrasonic crushing homogenizer
This type of homogenizer is mainly used for various tissue crushing / cell lysis, organelle, nucleic acid, protein extraction, and emulsification and homogenization of other industrial samples. The advantages are: easy to use, different samples can be processed by replacing different probes; emulsification and homogenization are good, suitable for single sample operation. Disadvantages: multiple samples cannot be processed at the same time. Different samples need to be replaced or cleaned, which increases the chance of cross-contamination between samples; it has certain influence on biological samples with special requirements.
2. Probe rotary blade homogenizer
This type is rotated by a grinding pestle in a homogenizer to achieve the purpose of separation, mixing, crushing and homogenization, and is suitable for processing tough samples. It is used to disperse animal / plant tissues, with lysate to extract nucleic acids, proteins, etc. It can also be used for industrial resins and pigments to make suspensions / emulsions. The main advantages of this type of homogenizer are: low speed, high torque, and no noise. It is easy to use. By changing different probes, it can process different amounts of samples. It is easy to operate and more suitable for single sample operation. Disadvantages: Can not process multiple samples at the same time, different samples need to be replaced or cleaned probes, increasing the chance of cross-contamination between samples; this type of homogenizer is not considered for the treatment of thick-walled samples such as bacteria, yeast and other fungi.
3. Slap homogenizer (also called percussion homogenizer, grinding bead homogenizer)
The flapping homogenizer thumps on the bag non-stop by thumping the plate. The resulting pressure can crush and mix the contents of the bag. Grinding bead homogenizer is to put the sample and the corresponding beads into the test tube through three-dimensional high-speed rotation and vibration, and grind the sample by high-speed beating of the grinding bead, homogenize to break the sample, and the application range is wide. It is used for the crushing of animal and plant tissues, algae, bacteria, yeast, fungi or mold, as well as various sporophytes, DNA / RNA, protein extraction. Its advantage is that it can efficiently process stubborn samples including bones, spores, soil, etc. Each homogenizer cup of the homogenizer is equipped with a homogenizing knife to avoid cross-contamination, and the operation is simple and efficient. It is better to handle brittle samples. The disadvantage is that it cannot process large-volume samples. The single sample processing volume is generally less than 1.5ml, and the consumption of consumables and equipment is relatively high.
Characteristics of homogenizer:
· Stable operation, low noise, easy cleaning, flexible maneuverability, continuous use, ultra-fine dispersion and emulsification of materials. It can be widely used in emulsification, homogenization and dispersion of industrial production.
· The material liquid can be refined and mixed under the triple action of squeezing, 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 and soy milk are homogenized under high pressure, which can significantly refine the fat globules in the dairy liquid, make it easy to digest and absorb after eating, and improve the use value.
· Used in the production of ice cream and other products, it can improve the fineness and looseness of the liquid, so that its internal texture is significantly improved.
Used in the production of emulsions, glues, juices, slurries, etc., it can prevent or reduce the stratification of the material liquid, improve the appearance of the material liquid, make its color more bright, the aroma is more concentrated, and the taste is more mellow.
Homogenizer application industry:
Biomedicine; food industry; daily chemical care products; paints and inks; nanomaterials; petrochemicals; printing and dyeing auxiliaries; paper industry; pesticides and fertilizers; plastics and rubber; power electronics;
Mainly used for tissue dispersion in the field of biotechnology, sample preparation in the field of medicine, enzyme treatment in the food industry, and in the pharmaceutical industry, cosmetics industry, paint industry and petrochemical industry.
Shanghai Qiaoyue slap homogenizer (also called percussion homogenizer, grinding bead homogenizer) product introduction:
JOYN brand tapping homogenizer is widely used in food microbiological analysis; homogenization of animal tissues, biological samples, cosmetics; meat, fish, vegetables, fruits, biscuits; microbiological analysis of drugs. The process of extracting bacteria from a solid sample becomes simple.
