The DSM screen (sieve bend screen) is mainly used for the separation of fiber, residue skin, and starch milk in the processing of corn and potato starch and the manufacture of modified starch. It can also be used for the extraction of high-purity professional starch required by the pharmaceutical industry and monosodium glutamate production.

Why Use BLU-HXS-01 Series Starch 120° Static DSM Screen?

The structure of an ordinary static pressure DSM screen includes profile wire, bottom support rod, middle lining, and sidelining.

The positional relationship between various components is: the profile wire is above, the bottom support rod is below the profile wire, the edge is lined at both ends, and the middle lining is between the profile wire and the bottom rib.

The profile wire is perforated and connected with the bottom reinforcement, and the bottom reinforcement and sidelining are connected with the middle lining, and the sidelining is generally welded with the bottom reinforcement at both ends.

Disadvantages of ordinary static pressure sieve bend screen

  • The profile wire and support rod are made of ordinary 316, which has poor corrosion resistance, impact resistance and wear resistance.
  • The profile wire adopts a 1.02 mm round wire, which has a poor filtering effect, and the fiber blocks the screen gap, which is not conducive to screen filtration and improving screen efficiency.
  • Because the bottom reinforcement is round, the welding is not firm and easy to be desoldered, and the surface flatness of the product is very poor, surface strengthening treatment and other treatment cannot be done, so that the product has low strength and short service life.

BLU-HXS-01 series products are designed to overcome the shortcomings of the prior art and provide a 120 ° static pressure DSM screen.  The utility model has the advantages of good wear resistance, strong filtering effect, firm welding, difficult desoldering, long service life, etc.

BLU-HXS-01 series 120° static pressure curved screen, including profile wire, bottom support rod, middle lining, and sidelining.

Advantage of BLU-HXS-01 Series Starch 120° Static DSM Screen

  • The material of profile wire and support bar is changed to double stainless steel 316L, which can improve its corrosion resistance, impact resistance and wear resistance.
  • The cross-section of the profile wires changed from round to trapezoid, which is conducive to the filtration of the screen and improves the efficiency of the screen. The circular filtration effect is poor. The screen not only plays the role of filtration but also cuts off the fiber in the starch slurry during filtration.
  • The profile wireis trapezoidal. After fine grinding, there will be a knife-edge, which can cut off the fiber and prevent the fiber from blocking the screen slot.
  • The support bars trapezoidal, which is convenient and firm for welding. The round bottom bar is not firmly welded and easy to be desoldered.
