JP 2000-116526 A Japanese Patent No. 3191645

  In the past, when making bread, it was necessary to start by obtaining flour obtained by milling grains such as wheat and rice, and mixing flour mixed with various auxiliary ingredients. Even with grain at hand (typically rice), it was difficult to make bread directly from it.

  The present invention has been made in view of the above points, and provides an automatic bread maker equipped with a convenient mechanism for manufacturing bread directly from cereal grains, and aims to make bread manufacturing more familiar. And

  In order to achieve the above object, the present invention provides an automatic bread maker that receives a bread container containing a bread-making raw material in a baking chamber in a main body and performs the kneading process, fermentation process, and baking process of the bread-making raw material. The blade rotation shaft provided at the bottom of the bread container is equipped with a grinding blade and a dome-shaped cover that covers the grinding blade and has a kneading blade on the outer surface, and the grinding blade rotates with respect to the blade rotation shaft And a clutch for connecting or disengaging the cover and the blade rotating shaft is interposed between the cover and the blade rotation shaft, and a recess for accommodating the cover is formed at the bottom of the bread container. It is said.

  According to this structure, the bread-making raw material can be manufactured in the bread container by putting the grain into the bread container and pulverizing it with the grinding blade. Thereafter, the bread-making raw material is kneaded with a kneading blade, and the fermentation and baking steps can be further advanced. Grain grains crushed in a bread container can be baked into bread in the bread container as they are, so that the grains remain in other containers, unlike crushed grains in other containers and then transferred to the bread container. There is no loss associated with the transfer, that is, not entering the bread container. In addition, the crushing blade and the kneading blade can be left in the bread container from the crushing of the grain to the baking of the bread, and the crushing blade and the kneading blade can be used properly only by reversing the rotation direction of the blade rotation shaft. It is easy to operate. Further, since the grinding blade grinds the grain within the cover, the grain does not scatter outside the bread container. Further, since the cover is housed in the recess and does not protrude from the bottom of the bread container, no large traces are left on the bottom of the bread.

  According to the present invention, in the automatic bread maker configured as described above, a gap is formed between the outer peripheral portion of the cover and the inner surface of the concave portion to allow the flow of the bread-making raw material. It is characterized by the formation of windows that connect the space.

  According to this configuration, the mixture of cereal grains and liquid existing on the concave portion enters the concave portion through the gap, enters the cover from the concave portion, and in the cover, the cereal grain is crushed by the pulverizing blade, and from the cover window. A circulation of returning to the top of the recess occurs, and the grain can be efficiently crushed.

  According to the present invention, bread can be baked using hand-held grains, and there is no need to purchase grain flour. In the case of rice, bread can be baked with rice of the desired degree of milling, from brown rice to white rice. And since it can consistently perform in the bread container in a baking chamber from the grinding | pulverization of a grain grain to baking of a bread | pan, there is little danger that a foreign material will mix in bread dough. Furthermore, unlike the case where the grain is crushed in another container and then transferred to the bread container, there is no loss associated with the transfer in which the pulverized grain remains attached to the other container. Since the crushing blade and the kneading blade can be kept in the bread container from the beginning to the end, the handling is easy, and the crushing can be performed without scattering the grains outside the bread container. Since the cover is housed in the recess and does not protrude from the bottom of the bread container, there is no possibility of leaving a large trace on the bottom of the bread. A gap that allows the flow of the bread-making material is formed between the outer periphery of the cover and the inner surface of the recess, and a window is formed in the cover so that the space in the cover communicates with the space outside the cover. The mixture of grains and liquid enters the recess through the gap, enters the cover from the recess, and the grain grains are crushed by the grinding blade in the cover, returning to the top of the recess from the cover window, efficiently. Grain grains can be crushed.

  Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, the left side of the figure is the front (front) side of the automatic bread maker 1, and the right side of the figure is the back (rear) side of the automatic bread maker 1. Further, it is assumed that the left hand side of the observer facing the automatic bread machine 1 from the front is the left side of the automatic bread machine 1, and the right hand side is the right side of the automatic bread machine 1.

  The automatic bread maker 1 has a box-shaped main body 10 constituted by an outer shell made of synthetic resin. An operation unit 20 is provided on the front surface of the main body 10. Although not shown, the operation unit 20 has operation keys such as a selection key for bread types (wheat flour bread, rice flour bread, bread with ingredients, etc.), a selection key for cooking contents, a timer key, a start key, a cancel key, and the like. A display unit is provided for displaying the group and the set cooking contents and timer reservation time. The display unit includes a liquid crystal display panel and a display lamp using a light emitting diode as a light source.

  The upper surface of the main body behind the operation unit 20 is covered with a lid 30 made of synthetic resin. The lid 30 is attached to an edge on the back side of the main body 10 with a hinge shaft (not shown), and rotates in a vertical plane with the hinge shaft as a fulcrum.

  A firing chamber 40 is provided inside the main body 10. The baking chamber 40 is made of sheet metal and has an open top surface, from which a bread container 50 is placed. The baking chamber 40 includes a peripheral side wall 40a and a bottom wall 40b having a rectangular horizontal section.

  A base 12 made of sheet metal is installed inside the main body 10. On the base 12, a bread container support 13 made of an aluminum alloy die-cast product is fixed at a location corresponding to the center of the firing chamber 40. The inside of the bread container support part 13 is exposed inside the baking chamber 40.

  A driving shaft 14 is vertically supported at the center of the bread container support 13. The pulleys 15 and 16 give rotation to the driving shaft 14. Clutchs are respectively disposed between the pulley 15 and the driving shaft 14 and between the pulley 16 and the driving shaft 14. When the pulley 15 is rotated in one direction to transmit the rotation to the driving shaft 14, The rotation is not transmitted to the pulley 16, and when the pulley 16 is rotated in the opposite direction to the pulley 15 to transmit the rotation to the driving shaft 14, the rotation of the driving shaft 14 is not transmitted to the pulley 15.

  The pulley 15 is rotated by a kneading motor 60 supported by the base 12. The kneading motor 60 is a saddle shaft, and the output shaft 61 protrudes from the lower surface. A pulley 62 connected to the pulley 15 by a belt 63 is fixed to the output shaft 61. The kneading motor 60 itself is of a low speed / high torque type, and the pulley 62 rotates the pulley 15 at a reduced speed, so that the driving shaft 14 rotates at a low speed / high torque.

  The pulley 16 is rotated by a crushing motor 64 that is also supported on the base 12. The grinding motor 64 is also a saddle shaft, and the output shaft 65 protrudes from the upper surface. A pulley 66 connected to the pulley 16 by a belt 67 is fixed to the output 65.

  The crushing motor 64 plays a role of giving high-speed rotation to a crushing blade described later. For this reason, a high-speed rotation type is selected as the grinding motor 64, and the reduction ratio between the pulley 66 and the pulley 16 is set to be approximately 1: 1.

  The bread container support unit 13 supports the bread container 50 by receiving a cylindrical pedestal 51 fixed to the bottom surface of the bread container 50. The pedestal 51 is also an aluminum alloy die cast product.

  The bread container 50 is made of sheet metal and has a bucket-like shape, and a handle (not shown) for handbags is attached to the lip. The horizontal section of the bread container 50 is a rectangle with rounded corners.

  A vertical blade rotating shaft 52 is vertically supported at the center of the bottom of the bread container 50 after taking measures against sealing. A rotational force is transmitted to the blade rotating shaft 52 from the driving shaft 14 through the coupling 53. Of the two members constituting the coupling 53, one member is fixed to the lower end of the blade rotation shaft 52 and the other member is fixed to the upper end of the driving shaft 14. The entire coupling 53 is enclosed by the base 51 and the bread container support 13.

  Protrusions (not shown) are formed on the inner peripheral surface of the bread container support 13 and the outer peripheral surface of the base 51, respectively. These protrusions constitute a well-known bayonet connection. That is, when the bread container 50 is attached to the bread container support part 13, the bread container 50 is lowered so that the protrusions of the base 51 do not interfere with the protrusions of the bread container support part 13, and the base 51 fits into the bread container support part 13. Thereafter, when the bread container 50 is twisted horizontally, the protrusion of the pedestal 51 is engaged with the lower surface of the protrusion of the bread container support portion 13 so that the bread container 50 cannot be pulled upward. By this operation, coupling of the coupling 53 is achieved at the same time. The twisting direction when the bread container 50 is attached coincides with the rotation direction of the kneading blade described later so that the bread container 50 does not come off even if the kneading blade rotates.

  A heating device 41 disposed inside the baking chamber 40 surrounds the bread container 50 and heats the bread-making material. The heating device 41 is constituted by a sheathed heater.

  A crushing blade 54 is attached to the blade rotation shaft 52 at a position slightly above the bottom of the bread container 50. The crushing blade 54 is not rotatable with respect to the blade rotation shaft 52. The crushing blade 54 is made of a stainless steel plate and has a shape like an airplane propeller, as shown in FIGS.

  A central portion of the pulverizing blade 54 is a hub 54 a that is fitted to the blade rotation shaft 52. A groove 54b that crosses the hub 54a in the diametrical direction is formed on the lower surface of the hub 54a. A pin (not shown) penetrating the blade rotation shaft 52 horizontally receives the hub 54a and engages with the groove 54b to connect the grinding blade 54 to the blade rotation shaft 52 in a non-rotatable manner. Since the crushing blade 54 can be easily pulled out from the blade rotating shaft 52, it is possible to easily perform washing after the bread making operation and replacement when the sharpness is deteriorated.

  A planar dome-shaped cover 70 is attached to the upper end of the blade rotation shaft 52. The cover 70 is made of an aluminum alloy die-cast product and covers the grinding blade 54. The cover 70 is rotatably fitted to the blade rotation shaft 52 and is received by the hub 54a of the grinding blade 54. Since the cover 70 can also be easily pulled out from the blade rotating shaft 52, the cleaning after the bread making operation can be easily performed.

  A planar square kneading blade 72 is attached to the outer surface of the cover 70 by a vertical support shaft 71 disposed at a position away from the blade rotation shaft 52. The kneading blade 72 is also an aluminum alloy die cast product. The support shaft 71 is fixed or integrated with the kneading blade 72 and moves together with the kneading blade 72.

  The kneading blade 72 rotates in a horizontal plane around the support shaft 71, and takes two postures, a folded posture shown in FIG. 3 and an open posture shown in FIG. In the folded position, the kneading blade 72 is in contact with the stopper portion 73 formed on the cover 70 and cannot be rotated clockwise with respect to the cover 70 any more. At this time, the tip of the kneading blade 72 slightly protrudes from the cover 70. In the open posture, the kneading blade 72 is separated from the stopper portion 73, and the tip of the kneading blade 72 protrudes greatly from the cover 70.

  The cover 70 is formed with a window 74 that communicates the space inside the cover and the space outside the cover. The window 74 is arranged at a height equal to or higher than the grinding blade 53. In the embodiment, a total of four windows 74 are arranged at 90 ° intervals, but other numbers and arrangement intervals can be selected.

  As shown in FIGS. 7 and 8, a total of four ribs 75 are formed on the inner surface of the cover 70 corresponding to the windows 74. Each rib 75 extends obliquely from the vicinity of the center of the cover 70 to the outer peripheral annular wall with respect to the radial direction, and the four ribs 75 constitute a kind of bowl shape. Further, each rib 75 is curved so that the side facing the bread-making raw material that presses toward it is convex. The grinding blade 54 rotates so that the lower edge of the rib 75 is grazed.

  A clutch 76 (see FIG. 8) is interposed between the cover 70 and the blade rotation shaft 52. The clutch 76 connects the blade rotation shaft 52 and the cover 70 in the rotation direction of the blade rotation shaft 52 when the kneading motor 60 rotates the driving shaft 14 (rotation in this direction is referred to as “forward rotation”). On the contrary, in the rotation direction of the blade rotation shaft 52 when the crushing motor 64 rotates the driving shaft 14 (rotation in this direction is referred to as “reverse rotation”), the clutch 76 connects the blade rotation shaft 52 and the cover 70. Is to be separated. In FIGS. 3 and 4, the “forward rotation” is counterclockwise rotation, and the “reverse rotation” is clockwise rotation.

  The clutch 76 includes a first engagement body 76a and a second engagement body 76b. The first engagement body 76 is fixed or integrally formed with the hub 54 a of the grinding blade 54, and is thus non-rotatably attached to the blade rotation shaft 52. The second engagement body 76b is fixed or integrally formed with the support shaft 71 of the kneading blade 72, and changes the angle as the posture of the kneading blade 72 changes.

  The clutch 76 switches the coupling state according to the attitude of the kneading blade 72. That is, when the kneading blade 72 is in the folded position shown in FIG. 3, the second engaging body 76b is at the angle shown in FIG. At this time, the second engagement body 76b interferes with the rotation path of the first engagement body 76a, and when the blade rotation shaft 52 rotates in the clockwise direction in FIG. Engaging with the engaging body 76 b, the rotational force of the blade rotation shaft 52 is transmitted to the cover 70 and the kneading blade 72. When the kneading blade 72 is in the open position shown in FIG. 4, the second engagement body 76b has an angle shown in FIG. At this time, the second engagement body 76b is retracted from the rotation track of the first engagement body 76a, and even if the blade rotation shaft 52 rotates in the counterclockwise direction in FIG. And the second engagement body 76b is not engaged. Accordingly, the rotational force of the blade rotation shaft 52 is not transmitted to the cover 70 and the kneading blade 72.

  At the bottom of the bread container 50, a recess 55 for accommodating the grinding blade 54 and the cover 70 is formed. The recess 55 is circular in a planar shape, and a gap 56 is formed between the outer periphery of the cover 70 and the inner surface of the recess 55 to allow the bread-making material to flow.

  Operation control of the automatic bread maker 1 is performed by the control device 80 shown in FIG. The control device 80 is constituted by a circuit board disposed at a suitable place in the main body 10 (preferably a place not easily affected by the heat of the baking chamber 40). In addition to the operation unit 20 and the heating device 41, the motor driver of the kneading motor 60 81, a motor driver 82 of the grinding motor 64, and a temperature sensor 83 are connected. The temperature sensor 83 is disposed in the baking chamber 40 and detects the temperature of the baking chamber 40. 84 is a commercial power source for supplying power to each component.

  Then, the process of manufacturing bread from cereal grains using the automatic bread maker 1 will be described with reference to FIGS. 11 to 19. Among them, the first aspect bread manufacturing process is shown in FIGS.

  FIG. 11 is an overall flowchart of the first aspect bread manufacturing process. In FIG. 11, the process proceeds in the order of impregnation process before grinding # 10, grinding process # 20, kneading process # 30, fermentation process # 40, and firing process # 50. Then, the content of each process is demonstrated.

  In the pre-grinding impregnation step # 10 shown in FIG. 12, first, in step # 11, the user measures the grain and puts a predetermined amount into the bread container 50. Rice grains are most easily available as grains, but other grains such as wheat, barley, straw, buckwheat, buckwheat, corn and the like can also be used.

  In step # 12, the user weighs the liquid and puts a predetermined amount into the bread container 50. A common liquid is water, but it may be a liquid having a taste component such as broth or fruit juice. Alcohol may be contained. Note that the order of step # 11 and step # 12 may be switched.

  The operation of putting the grain and liquid into the bread container 50 may be performed by removing the bread container 50 from the baking chamber 40 or may be performed while the bread container 50 is placed in the baking chamber 40.

  When the grain and liquid are put in the bread container 50 in the baking chamber 40, or when the bread container 50 containing the grain and liquid is attached to the bread container support part 13, the lid 30 is closed. Here, the user presses a predetermined operation key in the operation unit 20 to start the liquid impregnation time count. Step # 13 starts from this point.

  In Step # 13, the mixture of the grain and the liquid is allowed to stand in the bread container 50, and the grain is impregnated with the liquid. In general, since the impregnation is promoted as the liquid temperature increases, the heating means 41 may be energized to increase the temperature of the baking chamber 40.

  In step # 14, the control device 80 checks how much time has elapsed since the start of the resting of the grain and liquid. When the predetermined time has elapsed, the pre-grinding impregnation step # 10 ends. This is notified to the user by display on the operation unit 20 or by voice.

  Following the pre-grinding impregnation step # 10, the pulverization step # 20 shown in FIG. 13 is performed. Step # 21 is started when the user inputs grinding operation data (type and amount of grain, type of bread to be baked, etc.) through the operation unit 20 and presses the start key.

  In step # 21, the controller 80 drives the grinding motor 64 to rotate the blade rotation shaft 52 in the reverse direction. Then, the grinding blade 54 starts rotating in the mixture of the grain and the liquid. The cover 70 also follows the blade rotation shaft 52 and starts to rotate. The rotation direction of the cover 70 at this time is a clockwise direction in FIG. 3, and the kneading blade 72 turns to the open position by the resistance received from the mixture of the grain and the liquid when it has been in the folded position. When the kneading blade 72 is in the open posture, the clutch 76 disconnects the connection between the blade rotation shaft 52 and the cover 70 by the second engagement body 76b retracting from the rotation locus of the first engagement body 76a. At the same time, the kneading blade 70 in the open position hits the inner wall of the bread container 50 as shown in FIG. 4 and prevents the cover 70 from rotating. Thereafter, the blade rotating shaft 52 and the pulverizing blade 54 rotate at high speeds in opposite directions. Since the cover 70 and the kneading blade 72 are stopped, even if the grinding blade 54 rotates at a high speed, the mixture of grains and liquid does not vortex in the bread container 50. Therefore, the vortex swells at the periphery and does not spill out of the bread container 50.

  While the cover 70 stops rotating, the grinding blade 54 rotates at high speed to grind the grain. The pulverization by the pulverization blade 54 is performed in a state in which the liquid is immersed in the cereal grains, so that the cereal grains can be easily pulverized to the core. The ribs 75 extending from the vicinity of the center of the cover 70 to the outer peripheral annular wall suppress the flow of the mixture of the grain and the liquid in the same direction as the rotation direction of the grinding blade 54 and assist the grinding. That is, the rib 75 changes the flow of the mixture and acts to increase the chance of collision with the grinding blade 54. Since the pulverization is performed in the cover 70, the grains are not scattered outside the bread container 50.

  The pulverized grain and liquid mixture is guided toward the window 74 by the ribs 75 and is discharged out of the cover 70 through the window 74. Since the rib 75 is curved so that the side facing the mixture of the grain and liquid that presses toward it is convex, the mixture of the grain and liquid is unlikely to stay on the surface of the rib 75, and the window 74 smoothly It flows toward.

  As the mixture of the grain and liquid is discharged from the inside of the cover 70, the mixture of the grain and liquid existing on the recess 55 enters the recess 55 through the gap 56, and enters the cover 70 from the recess 55. to go into. Grain grains in the cover 70 are pulverized by the pulverizing blade 54 and return from the window 74 of the cover 70 onto the recess 55. Thus, by grind | pulverizing while circulating a grain, a grain can be grind | pulverized efficiently. Due to the presence of the ribs 75, the pulverized product generated by the pulverizing blade 54 is promptly guided to the window 74 and does not stay in the cover 70, so that the pulverization efficiency is further improved.

  Since the window 74 is arranged at a height above the crushing blade 53 or above, the direction in which the mixture of the crushed grain and liquid is discharged from the cover 70 is horizontal or diagonally upward. Circulation is promoted.

  In Step # 22, in order to obtain a desired pulverized grain, a pulverization pattern as set (however, if the pulverizing blade is continuously rotated, intermittently interlaced with a stop period, or intermittently rotated, the interval is taken. The control device 80 checks whether or not the rotation time length has been completed.

  When the pulverization pattern as set is completed, the process proceeds to step # 23 to finish the rotation of the pulverization blade 54, and the pulverization step # 20 ends. This is notified to the user by display on the display unit 22, voice, or the like.

  In the above description, the pulverization step # 20 is started by the user's operation after the pre-grinding impregnation step # 10. If the pulverization operation data is input in the middle of No. 10, the pulverization step # 20 may be automatically started after the pre-pulverization impregnation step # 10 is completed.

  Subsequent to the pulverization step # 20, the kneading step # 30 shown in FIG. 14 is performed. At the time of entering the kneading step # 30, the cereal grains and liquid in the bread container 50 are pasty or slurry dough raw materials. In the present specification, the material at the start of the kneading step # 30 is referred to as “dough raw material”, and the material that has come close to the intended state of the dough as the kneading progresses, ".

  In step # 31, the user opens the lid 30 and puts a predetermined amount of gluten into the dough material. Add seasoning ingredients such as salt, sugar and shortening as needed. The automatic bread maker 1 may be provided with an automatic charging device for gluten and seasoning materials, and the user can input them without bothering the user.

  The user inputs the type of bread and cooking details from the operation unit 20 before and after Step # 31. When the user presses the start key when the preparation is complete, the bread making operation that automatically continues from the kneading step # 30 to the fermentation step # 40 and further to the baking step # 50 is started.

  In step # 32, the control device 80 drives the kneading motor 60. When the blade rotation shaft 52 rotates in the forward direction and the cover 70 rotates in the forward direction, the kneading blade 72 changes from the open position to the folded position due to resistance from the dough material. In response to this, the clutch 76 connects the blade rotation shaft 52 and the cover 70 when the second engagement body 76b has an angle that interferes with the rotation locus of the first engagement body 76a. It rotates in the forward direction together with the rotating shaft 52.

  Here, the control device 80 energizes the heating device 41 and raises the temperature of the baking chamber 40. As the kneading blade 72 rotates, the dough raw material is kneaded and kneaded into a dough connected to one having a predetermined elasticity. When the kneading blade 72 swings the dough and knocks it against the inner wall of the bread container 50, an element of “kneading” is added to the kneading.

  If the cover 70 rotates, the rib 75 also rotates. As the rib 75 rotates, the dough raw material in the cover 70 is quickly discharged from the window 74 and assimilated into the dough raw material kneaded by the kneading blade 72.

  In step # 33, the controller 80 checks how much time has elapsed since the start of rotation of the kneading blade 72. When the predetermined time has elapsed, the process proceeds to step # 34.

  In step # 34, the user opens the lid 30 and puts yeast into the dough. At this time, the yeast used in the dough may be dry yeast. Baking powder may be used instead of yeast. For yeast and baking powder, an automatic dosing device can be used to save the user.

  In step # 35, the control device 80 checks how much time has passed since the yeast was added to the dough. When the time necessary to obtain the desired dough has elapsed, the process proceeds to step # 36, where the rotation of the kneading blade 72 is completed. At this point, the dough that is connected and has the required elasticity has been completed. Most of the dough stays above the recess 55 and only a small amount enters the recess 55.

  When baking the bread containing ingredients, the ingredients are introduced in any step of the kneading step # 30. An automatic loading device can also be used for material loading.

  Following the kneading step # 30, the fermentation step # 40 shown in FIG. 15 is performed. In step # 41, the dough that has undergone the kneading step # 30 is placed in a fermentation environment. That is, the control device 80 energizes the heating chamber 40 to the heating device 41 if necessary, and sets the temperature in a temperature zone where fermentation proceeds. The user arranges the dough, if necessary, and leaves the dough.

  In step # 42, the control device 80 checks how much time has passed since the dough was placed in the fermentation environment. If predetermined time passes, fermentation process # 40 will be complete | finished.

  Subsequent to the fermentation step # 40, the firing step # 50 shown in FIG. 16 is performed. In step # 51, the fermented dough is placed in a baking environment. That is, the control device 80 sends electric power necessary for baking to the heating device 41 and raises the temperature of the baking chamber 40 to the baking temperature zone.

  In step # 52, the control device 80 checks how much time has passed since the dough was placed in the baking environment. When the predetermined time has elapsed, the firing step # 50 ends. Here, since the completion of bread making is notified by display or sound on the display unit 22, the user opens the lid 30 and takes out the bread container 50. And bread is taken out from the bread container 50. Although the trace of the kneading blade 72 remains at the bottom of the bread, the cover 70 is housed in the recess 55 and does not protrude from the bottom of the bread container 50, so a large trace remains at the bottom of the bread. There is no such thing.

  Next, the second aspect bread making process will be described with reference to FIGS. 17 and 18. FIG. 17 is an overall flowchart of the second aspect bread manufacturing process. In FIG. 17, the process proceeds in the order of pulverization step # 20, post-pulverization impregnation step # 60, kneading step # 30, fermentation step # 40, and firing step # 50. Next, the content of the post-grinding impregnation step # 60 will be described based on FIG.

  In step # 61, the dough raw material formed in the pulverization step # 20 is left in the bread container 50. This dough raw material has not been subjected to the impregnation step before pulverization. While standing still, liquid soaks into the ground grain. The control device 80 energizes the heating device 41 as necessary to heat the dough material and promote the impregnation.

  In step # 62, the control device 80 checks how much time has elapsed since the start of standing. When the predetermined time has elapsed, the post-grinding impregnation step # 60 is finished. When the post-grinding impregnation step # 60 is completed, the process automatically proceeds to the kneading step # 30. The steps after the kneading step # 30 are the same as the first aspect bread making step.

  Then, the 3rd aspect bread-making process is demonstrated based on FIG. FIG. 19 is an overall flowchart of the third aspect bread manufacturing process. Here, the pre-pulverization impregnation step # 10 of the first aspect is placed before the pulverization step # 20, and the post-pulverization impregnation step 60 of the second aspect is placed after the pulverization step # 20. The steps after the kneading step 30 are the same as the first aspect bread making step.

  The pulverizing blade 54 can be used not only for pulverizing grains, but also for reducing the size of ingredients such as nuts and leafy vegetables. For this reason, bread containing fine ingredients can be baked. The crushing blade 54 can also be used for crushing ingredients other than ingredients mixed in bread and crude drug ingredients.

  In this embodiment, the single control device 80 can control the rotation of the grinding blade 54 and the rotation of the kneading blade 72 in association with each other. At the stage of kneading, the rotation suitable for the kind and amount of the grain is given to the grinding blade 54 and the kneading blade 72, and the quality of the bread can be improved.

  Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.

  The present invention is widely applicable to automatic bread machines used mainly in general households.
