Abstract
The plant comprises a single reactor divided into adjacent cells which communicate together with a limited passage opening. An inlet for a primary starch fraction and an inlet for a starch-reducing product open into one end-cell, an outlet for the glue connects to the other end-cell and an inlet for a secondary starch fraction opens into an intermediate cell. In this intermediate cell a baffle-plate is mounted. A stirrer is mounted in the reactor and comprises in each cell a stirring disc extending eccentrically relative to the geometrical reactor axis.
Claims7
A reactor for continuously preparing a two-component starch glue, said reactor having a geometrical axis and comprising:
- a. a plurality of cells adjacent in the direction of said geometrical axis, said cells forming,
- a first end cell at one end of said axis,
- a second end cell at the other end of said axis and
- intermediate cells between said first end cell and said second end cell,
- said cells having each a cylindrical inner wall
- b. partitions between adjacent cells, each partition being provided with a limited passage opening,
- c. an inlet for a primary starch fraction, said inlet opening into said first end cell,
- d. an inlet for an agent for gelatinizing said primary starch fraction, said inlet opening into said first end cell,
- e. an inlet for a secondary starch fraction, said inlet opening into one of said intermediate cells,
- f. an outlet for glue, which outlet connects to said second end cell,
- g. a stirrer comprising:
- a shaft rotatably mounted in the reactor and extending parallel to the reactor axis, through the passage opening in each of the partitions between the cells, said shaft having a geometrical axis lying at a distance from the reactor axis,
- in each cell a stirring disc mounted on said shaft, said disc having its center on the geometrical axis of the shaft and being provided with teeth on its circumference, and
- a drive mechanism connected to said shaft,
- h. means for providing a primary starch fraction, means for feeding the primary starch fraction to the inlet of subsection c, means for providing an agent for gelatinizing the primary starch fraction, means for feeding the agent for gelatinizing the primary starch fraction to the inlet of subsection d, means for providing a secondary starch fraction, and means for feeding the secondary starch fraction to the inlet of subsection e, and
- i. in the intermediate cell into which opens the inlet for the secondary fraction, a baffle-plate mounted on the inner wall of the cell, opposite to the stirrer shaft axis with respect to the geometrical axis of the reactor, said baffle-plate extending in parallel relationship with said geometrical axis of the reactor, the first end cell into which opens the inlet for a primary starch fraction and cells, if any, between the first end cell and the intermediate cell into which opens the inlet for the secondary starch fraction being free of baffle-plates on their inner wall.
