Selection of water chestnut starch cyclone

  Starch cyclone is a device that uses fluid pressure to produce rotary motion
When the starch milk enters the hydrocyclone at a certain speed, it makes a rotary motion after encountering the wall of the hydrocyclone
Due to the different centrifugal force, the starch in the slurry has a large centrifugal force, which can overcome the hydraulic resistance and move towards the wall
Under the joint action of its own gravity, it moves downward spirally along the wall
Due to the small centrifugal force, fine and small fibers, proteins and impurities move with the slurry before they get close to the wall
Driven by the follow-up feeding, the slurry continues to move downward and rotary, so the large particles of starch continue to concentrate around, while the small particles of fiber, protein and impurities stay in the ZX area, and the particle size increases from ZX to the wall, forming a layered arrangement As the slurry flows from the column part to the cone part of the hydrocyclone, the flow section becomes smaller and smaller
Under the compression of the shrinkage of the outer slurry, the fibers, proteins and impurities with light specific gravity have to change the surface direction and move upward to form an internal swirl, which is discharged from the overflow port, while the starch with large particles continues to move downward spirally along the wall of the hydrocyclone to form an external swirl, Z which is finally discharged from the underflow port, Become the main function of starch cyclone station: remove soluble and insoluble protein, fine fiber and sugar in starch milk to obtain high-quality starch milk

  Starch cyclone station is the leading product of the company in recent years
With the development of starch science and technology, the market's requirements for starch quality continue to improve, and the manufacturing and deep processing of starch develop very fast
Therefore, the quality and process matching of starch cyclone station directly affect the starch quality, The starch cyclone (station) of our company is made of high-quality stainless steel, the equipment surface is treated by special process, and the cyclone pipe is made of wear-resistant wool
The product quality is stable and the price is reasonable, which is deeply welcomed by the majority of starch users

Structure , Xlq hydrocyclone unit is composed of multi-stage hydrocyclones in a certain way, and each stage hydrocyclone is composed of multiple small-diameter liquid hydrocyclones in parallel
Each stage of cyclone needs to be installed with different number of cyclone pipes and a feeding pump according to its different process role in the cyclone unit
The pipeline is equipped according to the process requirements, and equipped with pressure gauge and other instruments, which are integrated with the cyclone
The whole unit is independent in the process, with compact structure and convenient installation SF

  In order to reduce the protein content of starch milk to less than 0
5%, when producing grain starch, the number of cyclone units shall not be less than nine, and the potato starch shall not be less than seven
When the protein content of crude starch milk separated from starch centrifuge does not exceed 2
5%, under the above conditions, after refining by multi-stage cyclone, the protein content of refined starch can be less than 0
5

  Characteristics of starch washing cyclone unit
Hydrocyclone is composed of several small-diameter liquid hydrocyclones
It is widely used in starch industry and similar industries
Generally, grade 7-23 is adopted
Starch milk enters from a certain stage and passes through all levels in sequence
The material flows out from the bottom of the first stage after Z, and the washing water enters from the feed pump of the first stage after Z, flows back in turn until the first stage before Z, and is discharged by the overflow of Dy stage
The purpose of this device is to further remove soluble and insoluble impurities in starch milk after separation of husband substance, which are mainly proteins
Insoluble protein is a part of husband substance
Soluble impurities include soluble protein and inorganic salts

There is a feed pump in front of each stage of hydrocyclone, which is connected with the underflow of the previous stage and the overflow of the next stage, and a blue filter is installed in front of the pump inlet
The pressure between the inlet and overflow port shall be kept between 4
2-6
3kg/cm, and the pump pressure shall be 6-8kg

The types of hydrocyclones include separation and classification type, washing type, clarification type and concentration type

BK cyclone unit technology is a liquid-liquid and solid-liquid separation technology introduced by our company from abroad
With unique structure and different combination forms, it can independently complete the operation tasks of separation, washing, clarification, concentration and screening units in food, medicine, fermentation, starch and other industries
It is especially suitable for manufacturers that originally produced 10000 tons of starch output, technical transformation, selection of production expansion, less investment and quick effect
Our existing products are starch washing cyclone units with an output of 10000-120000 tons / year, and experts are responsible for commissioning, which has SF unique uses in the starch industry
It completely simplifies the traditional refining process of separator or separation plus cyclone concentration in the past, so that the high protein content primary starch milk after fiber washing can complete the separation and intermediate concentration of gluten and the refined washing and concentration of starch milk in the cyclone unit at one time, so as to meet the requirements of refined starch milk entering the horizontal centrifuge
