Description

Detailed Description of the Invention

  The present invention relates to a technique for bonding a liquid raw material to a powder or a raw material equivalent thereto and a technique for asking it.

  When trying to rotate the raw material along the inner wall surface of the cylinder, various shapes such as flat plate type, round bar type, paddle type, shovel type, ribbon type, etc., with the effect that the rotary blade itself pushes the raw material directly The raw materials have been rotated using blades.

Problems to be solved by the invention

The conventional rotary blade pushes the raw material with the blade, cuts the raw material with the blade, and rotates the raw material while stirring. Then, for example, using the technique of Japanese Patent Application No. 2003-145534, the liquid raw material that has been microparticulated using a microparticulater is added to the powder raw material layer that rotates along the cylindrical inner wall surface from the side of the rotating shaft. As a result, the rotating blades provide rotational motion to the raw material when simultaneously trying to bring about uniform bonding, and at the same time, the powder raw material combined with the liquid raw material and the liquid raw material and the unbonded powder raw material are mixed by stirring. Doing so prevents even bonding.
In addition, if the raw material of the powder is a raw material that becomes a viscous component by combining with the liquid raw material, such as wheat flour, it is combined with the liquid raw material while the liquid raw material is still being added by adding a stirring action. Since the sticky component of the raw material is organized, it prevents the liquid raw material from being uniformly added to the powder raw material.

Means for solving the problem

As a means for rotating the raw material along the inner wall surface of the cylinder, a rotating blade as in the past in which the rotating blade itself has a function of pushing the raw material is not used. Instead, the rotating blade itself has a function of pushing the raw material and has a width that is not too wide in the rotation direction, and uses a thin curved plate-like rotating blade curved along the inner wall surface of the cylinder. As the material rotates, the powder material placed on the thin curved plate-like rotating blades is bent into a plate shape with a slope that is gentler than the rest angle of repose due to the centrifugal force generated by the rotational motion. Build on the rotating blades. This pile of raw materials pushes and rotates the powder raw material on the inner wall surface of the cylinder, the raw material being combined with the liquid raw material, and the raw material combined with the liquid raw material.
When the powder raw material on the inner wall surface of the cylinder collides with the powder raw material placed on the curved plate-like rotary blades as the rotation rotates, the powder raw material placed on the curved plate-like rotary blades is slightly affected. Replacement is performed. However, since the powder raw material placed on the curved plate-like rotary blade is pressed in the direction of the inner wall surface of the cylinder by centrifugal force, there is little change. However, the appearance changes when the bond between the powder raw material and the liquid raw material begins.
When the powder raw material that has increased in mass by combining with the liquid raw material on the inner wall surface of the cylinder collides with the powder raw material placed on the curved plate-like rotary blade, the powder with a small mass on the curved plate-like rotary blade The raw material is blown off and replaced with the powder raw material combined with the liquid raw material. After all the raw materials on the curved plate-shaped rotating blades are combined with the liquid raw material, when a raw material with a larger mass combined with more liquid raw materials collides, it combines with fewer liquid raw materials. Raw material with a small mass is flipped and replaced. In this way, the raw material on the inner wall surface of the cylinder and the raw material on the curved plate-like rotary blade are evenly combined with the liquid raw material.
The rotating blade is not a curved plate with a curved surface that is purely along the inner wall surface of the cylinder, but the rotating inner surface is a curved surface along the inner wall surface of the cylinder, and the rotating shaft is a rotating blade with a flat surface. Even if the side of the shaft has some unevenness, and even if the front and back of the plate are close to a flat surface, there is no significant difference in the above action and effect.

The curved blades along the inner wall of the cylinder that cause the rotational movement of the raw material may be several independent blades, or a series of blades extending across the width of the cylinder in the direction perpendicular to the direction of rotation. But you can. Moreover, there may be a plurality of connected blades. The blades may extend straight along the inner wall surface of the cylinder or may be curved.
However, when the number of blades is too large and the raw material on the inner wall surface of the cylinder is too small, or the width in the rotational direction of the curved plate-shaped blades is too wide and a raw material with a different degree of coupling with the liquid material collides. It must be ensured that the replacement due to the loading and unloading of the raw material does not become difficult. Moreover, it is desirable that the rods connecting the rotating shaft and the curved plate-like rotating blades have a shape with little action of stirring the raw material on the inner wall surface of the cylinder.

  Even if a curved plate-shaped blade extending to the full width of the left and right sides of the cylinder is attached at an angle to the direction of rotation instead of being attached at right angles to the direction of rotation, the raw material is rotated in the same way. The powder raw material and the liquid raw material can be combined. In this way, the raw material on the inner wall surface of the cylinder moves not only in the direction of rotation but also in the direction of the length of the cylinder.

  For example, if two blades connecting the left and right sides of the cylinder are provided with the direction inclined to the direction of rotation reversed, the raw material on the inner wall surface of the cylinder is left to the right with respect to the direction of travel as the blades rotate. Move alternately.

  If the rotational speed is reduced at the time when the combination of the powder raw material and the liquid raw material is completed, the raw material on the curved plate-like rotary blade leaves the rotary blade.

  If irregularities that run at a right angle or near a right angle with respect to the direction of rotation are provided on the surface on the side of the rotation axis of the curved plate-like rotary blade of item 0007, the sticky component is organized and hardened like flour. Since the rotating blades with irregularities act on the combination of the powder raw material and the liquid raw material with the properties to become a rotating part while changing the place of contact with the rotation, it can also be kneaded .

Embodiments will be described with reference to the drawings. In the cross-sectional view and FIG. 1 and the cross-sectional view and FIG. 2, 1 is fixed by a cylinder of the outer frame. Reference numeral 2 denotes an atomizing device that rotates at a high speed to finely pulverize the liquid raw material and adds it to the powder raw material layer on the inner wall surface of the cylinder or the powder raw material on the rotary blades from the rotating shaft side. 3 and 4 are atomization blades. Reference numeral 5 denotes a rotating shaft of the atomizer. Reference numerals 6 and 7 denote curved blades that are curved along the inner wall surface of the cylinder. It is a continuous blade extending to the left and right widths in the direction of the length of the cylinder along the inner wall surface of the cylinder. There are two rotating blades 6 and 7 at positions opposed to each other with the atomizing device interposed therebetween, and the charged powder raw material is rotated along the inner wall surface of the cylinder. The rods 8, 9, 10 and 11 are connected to the rotary shaft 12 by rods. The rotary shaft 5 of the atomizer and the rotary shaft 12 of the rotary blade rotate separately at a rotation speed suitable for each rotation. In order to prevent adhesion and adhesion, the surface of the atomizer including the inner wall surface of the cylinder, the rotating blades, and the atomizing blades is coated with Teflon.
In both cross-sectional views, the powder raw material inlet provided in the upper part of the cylinder and the dough outlet provided in the lower part of the cylinder are omitted.

  When a powder raw material is introduced into the inside of the cylinder from the raw material inlet provided in the upper part of the cylinder 1, the raw material is placed on the inner wall surface of the cylinder at the lower part of the cylinder and on a rotating blade partly positioned below. A part of the raw material is also placed on the atomizer 2. When the atomizer is rotated without supplying the liquid material, the powder material placed on the atomizer is scattered in the direction of the inner wall surface of the cylinder. The rotary blades 6 and 7 are rotated at a speed that does not cause the powder raw material to rotate too fast along the inner wall surface of the cylinder. At this time, the rotary blades 6 and 7 rotate with the powder material placed on the rotary shaft side. The powder raw material lays a gentle mountain on the rotary blades 6 and 7 with the axis of the rotation axis at the top. The atomizing device 2 is rotated at a high speed to start supplying the liquid raw material. The liquid material is atomized by the atomizing blades 3 and 4 and is added to the powder material on the inner wall surface of the cylinder and the rotating blades. The raw material combined with the liquid raw material and the unbonded raw material are switched on the rotation axis side and the cylindrical inner wall surface side of the powder raw material layer rotating along the cylindrical inner wall surface. The exchange of the raw material on the blade also occurs, and the fine liquid raw material is uniformly added to the powder raw material.

  When the rotation of the rotary blades 6 and 7 is dropped to the point of stop after supplying the liquid raw material, the raw material on the rotary blades is separated from the rotary blades. The discharge port provided at the bottom of the cylinder is opened to take out the raw material after adding the liquid raw material.

The invention's effect

  The present invention is implemented in the form described above, and has the following effects.

  In the action of urging the raw material on the cylindrical inner wall surface caused by the raw material that builds a mountain at a gentler angle than the rest angle of repose on the curved rotary blade along the cylindrical inner wall surface, the rotary blade itself The agitation action as provided by conventional rotating blades that push the raw material does not occur. Therefore, for example, when applying the liquid raw material finely divided from the rotation axis side to the powder raw material layer rotating along the inner wall surface of the cylinder using the technique of Japanese Patent Application No. 2003-145534, Compared to the case where the raw material is rotated along the inner wall surface of the cylinder using the conventionally used rotary blade, the blades push the raw material directly, and a more uniform combination of the powder raw material and the liquid raw material is used. Can be obtained in a shorter time.

  Until the supply of the liquid raw material is completed and the rotary blade is once stopped or decelerated and the raw material on the rotary blade leaves the rotary blade, there is almost no stirring and mixing action on the raw material. Therefore, it is hardly necessary to carry out stirring and mixing to eliminate the uneven supply of the liquid raw material after the addition of the liquid raw material as in the past.

The effect is greater for raw materials with finer particles such as flour. When the powder raw material particles are fine, fine air between the raw material particles shows the property of clinging to the particles, and when trying to diffuse and infiltrate the liquid raw material from the place where the liquid raw material was added excessively, The clinging air does not give way to the liquid material that is moving.
For this reason, once the uneven bonding between the liquid raw material and the liquid raw material is made, it takes a long stirring and mixing time to eliminate the uneven bonding between the powder raw material and the liquid raw material. If the technique of rotating this raw material is used in the technique of Japanese Patent Application No. 2003-145534, the liquid raw material can be uniformly added to the entire powder raw material until the addition of the liquid raw material is completed, so the stirring time for homogenizing the liquid raw material In the case of flour or the like, a high-quality dough can be obtained simply by kneading the whole and organizing the sticky components after adding the liquid raw material.

It is sectional drawing of the mixer which adds the liquid raw material highly atomized from the rotating shaft side to the powder raw material which rotationally moves along a cylindrical inner wall surface. A rotating blade according to the present application is used as means for rotating the raw material along the inner wall surface of the cylinder. It is sectional drawing which changed the direction which looks at 90 degree | times of the surface which connects a and b.
