Cassava starch desander price

The utility model relates to a starch milk desander
A plurality of primary desanders are composed of an upper Diyi cylinder and a lower transparent Diyi conical cylinder
The outer wall of the Diyi cylinder is provided with a feed inlet, the top end of the Diyi cylinder is connected with a discharge pipe, the discharge pipe on each Diyi cylinder is connected with the main discharge pipe, and the bottom end of the Diyi conical cylinder is connected with the primary return pipe; The upper end of the secondary cylinder is connected with the second return cone, and the upper end of the secondary cylinder is connected with the second return cone
The utility model adopts the conical cylinder of the transparent primary desander, and opens the secondary desander by observing whether the fine sand is mixed with starch milk when it spirals down to the primary return pipe along the inner wall of the conical cylinder of the primary desander, so as to save the production cost and improve the work efficiency
In the production of corn, potato and sweet potato starch, the desander cyclone is usually used to remove the fine sand contained in the starch milk
The separation principle of the desanding cyclone is that the materials to be separated enter the cylindrical part of the cyclone along the tangent direction at a certain speed for circular rotation, and the materials with different specific gravity obtain different centrifugal force
The larger centrifugal force than the large fine sand (heavy phase) is thrown to the outer layer of circular motion for external swirl, and the starch emulsion (light phase) with small specific gravity is in the inner layer of circular motion to form internal swirl
These materials move downward in a spiral shape, and the fine sand spirals down to the bottom outlet along the inner wall of the conical cylinder on the cyclone
The starch emulsion rotating and falling in the inner layer of circular motion is blocked by the underflow port and discharged from the top of the cyclone in the same upward motion
At present, in the desanding process of starch emulsion, multiple primary desanders and one secondary desander are used
The heavy fine sand (heavy phase) in the primary desander enters the secondary desander through the return pipe, and the heavy fine sand (heavy phase) in the secondary desander enters the sand collector
Among them, the conical cylinder at the bottom of the primary desander is made of steel, and the working condition of materials in the conical cylinder cannot be known from the surface of the desander
Therefore, it cannot be guaranteed that the starch milk (light phase) with small specific gravity will enter the return pipe with the fine sand (heavy phase) with large specific gravity during processing
Therefore, it is necessary to open the secondary desander to remove the fine sand returned at the primary
The primary desander and secondary desander currently used are of the same specification, However, compared with the primary Desanding, most of the secondary desanders are fine sand, so there is no need to do too long movement like the primary desander to separate the starch milk
In this way, Jiangdi not only improves the processing efficiency, but also improves the production cost
In order to solve the technical problems existing in the background technology, the utility model proposes a starch milk desander, which opens the secondary reflux by observing the fine sand state entering the secondary desander, saves the production cost and improves the work efficiency
