Supply Anhui Baikang potato starch machinery and equipment

  The design of the cleaning machine adopts countercurrent washing, that is, the cleaning water enters the cleaning machine from the material outlet; The materials enter the rotating drum, complete the cleaning in the tumbling collision, and effectively remove the skin of the materials
The cleaned sediment skin falls between the drum and the inner wall of the water tank through the mesh, moves forward under the push of the blades, and discharges the equipment through the overflow tank
Potato starch is mainly stored in the fleshy part of the root tuber
The raw material particles are relatively large and the internal tissue is not easy to be damaged
Repeated filing can destroy the tissue structure of the potato tuber, so that the small starch particles can be smoothly separated from the root tuber and improve the starch extraction rate

The materials enter the filing housing through the upper inlet and are crushed by the impact, shear and grinding of the high-speed moving saw blade
The lower part of the rotor is provided with a screen
The materials smaller than the size of the screen hole in the crushed materials are discharged through the screen plate, and the particles larger than the size of the screen hole are blocked on the screen plate to continue to be hit and ground by the saw blade, Z and then discharged out of the machine through the screen plate

The centrifugal screen is that the potato and wheat starch slurry after filing and desanding evenly enters the bottom of the screen basket through the feed structure, and the screen basket rotates at high speed driven by the power transmission part
The starch slurry enters the screen surface through the powder mechanism
Under the action of gravity and centrifugal force, the slurry makes a circular motion along the screen surface and moves to the edge of the screen basket at the same time
Under the spray of the washing system, fine starch particles are discharged through the screen and discharged by the defoaming pump under the screen
Larger starch particles cannot be discharged through the screen and gradually sink into the slag bin and discharged by the slag pump
During the process of moving to the edge of the sieve basket, potato residue and starch slurry are continuously washed by washing water to remove the adsorbed free starch in the residue slurry
In addition, under the action of the recoil pipe at the back of the screen surface, the fine slag attached to the screen life can be removed, which can effectively avoid the blockage of the screen surface and ensure the normal operation of the equipment

The desander uses the principle of centrifugal separation to remove sand
Since the water inlet pipe is installed at the eccentric position of the cylinder, when the water passes through the water inlet pipe of the cyclone desander, it first forms an oblique downward surrounding fluid along the tangential direction around the cylinder, and the water rotates downward
When the water reaches a certain part of the cone, it rotates upward along the axis of the cylinder, Z and then is discharged through the water outlet pipe, Under the action of fluid inertial centrifugal force and its own gravity, impurities fall into the conical slag bucket at the lower part of the equipment along the cone wall
Components are set at the lower part of the cone to prevent sundries from rising
When the sundries accumulated in the slag bucket reach a certain degree, as long as the manual butterfly valve is opened, the sundries can flow out of the cyclone desander under the action of water flow

The starch slurry enters the middle cavity of the cylinder block from the feed inlet of the cyclone through the starch pump
The starch slurry enters the inlet of the cyclone pipe and enters the cyclone pipe along the tangent direction of the cyclone pipe
In the cyclone pipe, each component of the material rotates according to the spiral line to generate centrifugal force
When the material goes down to the conical part, due to the different relative density (specific gravity) and particle size of each component The centrifugal force is different due to different shapes, and the component starch with high relative density obtains a large centrifugal force, which is thrown along the outer spiral to the inner wall of the cone and then dropped along the wall to the bottom outlet; When the relative density of protein and water is small, the centrifugal force is small, the inner spiral vortex in the reverse rotation direction is formed by the resistance of the bottom flow port when the inner spiral motion drops close to the lower part of the cone, and the inner spiral vortex rises to the top flow port for discharge, so as to achieve the purpose of separation of each group

The vacuum drum suction filter adopts the method of vacuum suction filtration to realize the separation of solid particles and liquid
During operation, the speed regulating motor drives the drum to rotate in the slurry tank, and the vacuum pump generates vacuum inside the drum
Under the action of differential pressure, the suspended solution of materials forms a uniform coating on the surface of the drum
When a certain thickness is reached, the starch is scraped off by the pneumatic scraper, and the filtrate enters the steam water separator, so as to achieve the purpose of starch, water and gas separation

The cold air enters the radiator plate through the air filter, and the heated hot air flows into the drying air duct
At the same time, the dried wet material enters the hopper of the feeding unit from the wet starch inlet, and is transported into the elevator through the feeding auger
The elevator rotates at high speed to throw the wet material into the dry air duct, so that the wet material is suspended in the high-speed hot air flow for heat exchange, After the materials are dried, they enter the cyclone separator with the air flow, the separated dry materials and finished products are discharged through the closed air winch, and the finished products are screened, packaged and stored in the warehouse; The separated tail gas is pumped Z into the tail gas duct by the tail gas fan and sent to the atmosphere
