The front end portions (other end portions) of the blender units 28a and 28b are floating ends 38 and 38 that are not supported by a bearing or the like. The end surfaces of these floating ends 38 and 38 are covered with end surface covers 31 and 31. On the other hand, a space between the pump screws 7a and 7b and the stirring blades 34a and 34b serves as a secondary material charging portion 52. The secondary material from the outside of the pump is formed on the upper surface of the blender casing 3 in the secondary material charging portion 52. Are formed in the blender casing 3. These inlets 23, 24, and 25 are formed with a diameter corresponding to the addition ratio of the auxiliary material to the transferred object Q. Incidentally, the diameter of the middle inlet 23 is the largest, and the inlet 24 near the stirring blade part 34 a and the inlet 25 near the stirring blade part 34 b are formed to be somewhat smaller in diameter than the inlet 23. Yes. On the other hand, a discharge port 19 is formed on the bottom surface of the blender casing 3 below the free ends 38, 38 of the mixing rotary shafts 29, 29 for discharging the mixture of the transferred material Q and the auxiliary material to the outside of the pump. Has been. A pipe part 44 having a ferrule part 17 is connected to the lower surface opening edge of the blender casing 3 surrounding the discharge port 19, and a pipe 37 is connected to the ferrule part 17 of the pipe part 44 and fixed by a clamp band 36. Is done. The tip of the pipe 37 is connected to a mixture receiving container or the like.

For ease of observation, only one stirring blade plate portion 34a is shown in FIG. 6, but the other stirring blade plate portion 34b (not shown) is also provided. On the outer peripheral surfaces of the pair of mixing rotating shafts 29, 29, spiral blade-shaped stirring blade portions 34a, 34b are projected outward in the rotational axis radial direction. These stirring blade portions 34a and 34b are both provided in a spiral arrangement opposite to the spiral direction of the pump screws 7a and 7b connected to the mixing rotary shafts 29 and 29. The pair of stirring blades 34a and 34b are formed so as to be able to rotate by screwing in a non-contact manner. In addition, a plurality of through portions (examples of passage portions) 35, 35, 35,... Capable of passing the material to be transferred Q are respectively provided in the stirring blade portions 34a and 34b. It is formed penetrating in the direction of the coating arrow F). These penetrating portions 35, 35, 35,... Go from the outermost peripheral surface 34A in the radial direction of the rotation axis of the stirring blades 34a, 34b toward the axis Xa, Xb of the mixing rotation shafts 29, 29. It is formed as a notch cut out. A connecting member 32 used for connecting to the pump screws 7a and 7b is fixed to the ends of the mixing rotary shafts 29 and 29. This connecting member 32 is positioned in the circumferential direction by a pin fitted into a recessed part at the tip end surface of the base 7 </ b> A, and a pin attached to the pin hole 33. A relatively large gap is provided between the outer peripheral surface 34 </ b> A of the stirring blade portions 34 a and 34 b and the inner peripheral surface 3 </ b> A of the blender casing 3. Further, the stirring vane portion 3 4a, 34b is the axis Xa of the mixing rotary shaft 29, the inclination with respect to Xb, mixed axial-29 is rotated in the direction of rotation of the provisions (arrows Ra, Rb) The material to be transferred and the auxiliary material are set so that they can be pushed back toward the one end side of the blender casing 3 when moving. That is, blender casing 3, a mixing rotary shaft 29, stirring vane plate 3 4a, 34b, and blender unit 53 through the through region 35 is formed, the blender 101 from the sub material charging section 52 and the blender unit 53 is configured Thus, the blender-equipped pump 1 is constituted by the pump bearing portion 5, the pump portion 51, and the blender 101.

  Next, the operation of the blender-equipped pump 1 configured as described above will be described. Here, an example is shown in which a “molten candy material” having a relative viscosity of 50 Pa · s (@ 100 ° C.) is used as the high-viscosity transfer object Q. The molten candy material is a sugar liquid obtained by heating and boiling raw materials such as sugar and starch syrup. Then, the auxiliary material is input from the input ports 23, 24 and 25. For example, heated buttered butter is press-fitted by pump power or the like from the charging port 23, and heated and melted chocolate is press-fitted by pump power or the like from the charging port 24. It shall be press-fitted with pump power.

  First, when the pump screw 7a is rotated in one direction (the direction of arrow Ra in FIG. 7B) by the rotational drive of the motor M, the pump screw 7b to which power is transmitted via the synchronous gears 13a and 13b is reversed (see FIG. 7 (b) in the direction of arrow Rb). The rotational speed of the pump screws 7a and 7b is, for example, 100 to 1000 rpm. Then, the transferred object Q in the hopper enters the pump chamber 6 from the hopper through the pipe portion 21 and the intake port 18 of the pump casing 2. The transferred object Q that has fallen into the pump chamber 6 is pumped in the direction of the black arrow F by the pump action of the pump screws 7a and 7b, and passes through the connection port 14 of the blender casing 3 from the discharge port 55 of the pump casing 2. Then, it is transferred toward the blender units 28a and 28b in the blender casing 3. Here, the transported material Q was joined together with the melted butter pressed from the charging port 23 of the auxiliary material charging unit 52, the molten chocolate pressed from the charging port 24, and the molten fat and oil pressed from the charging port 25. Thereafter, both arrive at the blender units 28a and 28b.

  As shown in FIG. 7, the combined product Q, melted butter, melted chocolate, and melted fat and oil are on the upstream side (connection port 14) of the stirring blade portions 34 a and 34 b of the blender units 28 a and 28 b. And is moved in the push-back direction or the rotational axis circumferential direction as indicated by arrows ga and gb. On the other hand, a part of the merged material passes through the through portions 35, 35, 35,... As shown by the arrow f without contacting the plate surfaces of the stirring blade plates 34 a, 34 b, and the next stage plate. Reach the plane. Then, the merged material pushed back on the plate surface and the merged material that has passed through the through portions 35, 35, 35,... The mixing action by such pushing back movement and passing movement is repeated, and the transferred object Q and the auxiliary material are efficiently and reliably mixed to form a mixture. The pushing back force by the plate surfaces of the stirring blade portions 34a, 34b is not so large, the gap between the stirring blade plates 34a, 34b, and the inner peripheral surface of the stirring blade plates 34a, 34b and the blender casing 3 Since the gap between 3A is sufficiently large, the mixture can move in the blender units 28a and 28b by the transfer force generated by the pumping action of the pump screws 7a and 7b, and is discharged from the discharge port 19 after being sufficiently mixed. The mixture discharged from the discharge port 19 is accommodated in a receiving container, then molded in a mold, and allowed to cool to become a candy product.

As described above, according to the blender-equipped pump 1 of this embodiment, the transferred object Q, which is a fluid, has a gap G between the pump screws 7a and 7b, and the pump screw 7a or 7b and the storage chamber 52. Since it cannot pass through the gap H with the inner peripheral surface 2A, it is pumped under the pump action of the pump screws 7a, 7b. At this time, since the pump screws 7a and 7b and the inner peripheral surface 2A of the pump casing 2 are not in contact with each other, no shear force is applied to the transferred object Q without generating metal wear powder. That is, food, medical products, etc. can be transported without alteration. And the to-be-transferred object Q discharged from the pump screws 7a and 7b through the discharge port 55 can reach the blender units 28a and 28b after joining with the auxiliary material from the input ports 23 to 25. The combined product is efficiently stirred and mixed by the blender units 28a and 28b. That is, it is possible to perform both the transfer of the transfer object Q and the auxiliary material and the stirring and mixing with one unit.
Moreover, since the blender part 53 is arrange | positioned adjacent to the pump part 51 in the main body casing 4, piping does not exist among them. Therefore, it is not necessary to clean the pipe after using the apparatus, which is preferable in terms of hygiene, and is particularly preferable when handling foods. In addition, since the pump unit 51 and the blender unit 53 have a side-by-side integrated structure, the apparatus can be installed without taking up a large space.

  Further, as described above, since the stirring blade plates 34a and 34b of the blender units 28a and 28b are arranged in a spiral direction opposite to the spiral direction of the pump screws 7a and 7b, the stirring blade plate portion 34a. , 34b and the passing action of the penetrating portion 35, the combined product can be mixed efficiently. And since the penetration part 35 is a notch part notched from 34 A of outer peripheral surfaces, it can manufacture easily using a cutting machine and can take a large penetration area compared with penetration parts, such as a circular hole. Thereby, since the passing amount of the mixture becomes large, the amount of stirring can be increased, and the mixing efficiency can be further increased.

In addition, in said Embodiment 1, although the penetration part notched toward the rotating shaft center was illustrated from the outer peripheral surface of the rotating shaft radial direction outermost part of the stirring blade board part, this invention is not limited to it. In addition to the above-mentioned notch, the through-hole formed through the stirring blade plate in the transfer direction of the object to be transferred is a through-hole (round hole, long hole) not connected to the outer peripheral surface of the stirring blade plate portion. It may be a circular hole, a polygonal hole or the like). Even if it is such a through-hole, if it is formed large, a sufficient mixture passing effect can be obtained.
In the first embodiment, the example in which the pair of blender units 28a and 28b are connected to both the other end portions of the two pump screws 7a and 7b is shown. However, any one of the pump screws 7a and 7b is used. A blender pump in which only one blender unit is connected to only one is also included in the present invention .

As the object to be transported object Q of high viscosity to be used in transport and撹拌混case according blender with pump of the present invention, in addition to the molten candy material described above, for example syrup, food such as miso, cosmetics such as creams In addition, industrial materials such as molten synthetic resins, or medical materials are also included.
