Washing cyclone

The washing cyclone can remove the soluble and insoluble protein and the micro fiber in the starch milk. The vertical starch washing cyclone consists of a shell and a gland. The shell is provided with an upper overflow port, a bottom flow port and a lower overflow port. The shell and the cover are connected by bolts. The cover is fixedly provided with a lifting ring. The cover is connected with the upper swirl core through the upper isolation pressure ring. The upper swirl core is connected with the lower swirl core through the lower isolation pressure ring. Both the upper swirl core and the lower swirl core are provided Cyclone tube. Since the gland is set on the top of the cyclone, the cyclone core and cyclone tube can be taken out directly from the top by using the aerial flat car, which completely avoids the manual pulling out of the heavy cyclone core from the side and causing harm to workers···

Product introduction

Washing cyclone It is impossible to remove soluble starch and soluble protein from milk. The vertical starch washing cyclone consists of a shell and a gland. The shell is provided with an upper overflow port, a bottom flow port and a lower overflow port. The shell and the cover are connected by bolts. The cover is fixedly provided with a lifting ring. The cover is connected with the upper swirl core through the upper isolation pressure ring. The upper swirl core is connected with the lower swirl core through the lower isolation pressure ring. Both the upper swirl core and the lower swirl core are provided Cyclone tube. Since the gland is set on the top of the cyclone, the cyclone core and cyclone tube can be taken out directly from the top by using the aerial trolley, which completely avoids the injury to workers caused by manually pulling out the heavy cyclone core from the side, and ensures the cleaning and maintenance of the equipment under safe conditions.

 Washing cyclone

Basic technology

The basic technology of starch washing is to use a series of starch grading to remove insoluble protein, and counter current washing to remove soluble protein. Because the diameter of corn starch granules is 10-20 μ m, and the specific gravity is about 1.6, while the diameter of corn protein granules is 4-8 μ m, and the specific gravity is about 1.06. The granule size of "a" is called "granule size of about 1.4" for the granule size of "a", which has a "double peak size". Production practice has proved once again that the difference of particle size and specific gravity can be used to divide the particles into starch flow and protein flow by sedimentation process. Due to the centrifugal force, the rapidly increased density area in the starch washing cyclone is more suitable for this starch washing process. The countercurrent washing process is that the washing water flows in the opposite direction with the starch milk to be washed. The cyclone system of each stage provides the conditions for countercurrent washing and classification of each particle. It is very important to control the temperature of starch granules in the starch washing system when the temperature of starch granules in the washing process is higher than 60 ℃.

Structural features

Hydrocyclone is mainly composed of cyclone barrel, frame, pipeline, exhaust valve, sampling valve, blowdown valve, feed pump, pressure gauge, control system, touch screen and other relatively independent parts. Equipment debugging is generally arranged at the user's production site due to the relationship of raw materials. The main structural characteristics of the cyclone are vertical, which makes good use of the gravity of the material weight, improves the discharging speed and effect of the underflow, increases the material handling capacity, and makes the starch washing cyclone compact in structure and small in floor area.

 Washing cyclone

working principle

Its working principle is as follows: the mixed fluid with high pressure enters at a high speed from the tangent direction of the feed inlet and rotates at a high speed. Under the action of centrifugal field force, the material with large specific gravity (weighing phase) is thrown to the wall of the device and discharged from the underflow port; the material with small specific gravity (also known as light phase) is squeezed to the middle layer and discharged from the overflow port.

When the pressure of each pump is up to 0.6MPa, it will enter into the control system by touching the air inlet valve and exhaust valve.
