Description

  The present invention relates to an electric heating type Baumkuchen baking machine.

  The inventor has already obtained Patent No. 3686671 for a Baumkuchen calciner using a gas burner as a heating source, and as a second embodiment of this patented invention, the single firing described with reference to FIGS. The reciprocating arc motion type Baumkuchen calciner is considered to be a known technique that is most similar to the present invention.

Japanese Patent No. 3686671

  However, since the heating source of the Baumkuchen calciner is an infrared burner (8) and a pipe burner (9), it can be kept in a high temperature and high humidity state with a gas that also generates water vapor, and has a soft feeling and a perfect (wet) While there is an advantage that you can get a baked state of Baumkuchen that is rich in feeling, it is not possible to keep the baked dough clean due to the generation of exhaust gas, dust, etc. Especially connection work with gas supply source and safety work on fire fighting etc. Therefore, for example, it is difficult to adopt a usage method that is installed on the floor above the floor and instantly demonstrated and sold.

  The present invention aims to improve such a problem, and in order to achieve the object, in claim 1, a firing furnace defined in the central part of the installation machine casing,

  A pair of parallel rolling pin holding arms supported so as to be able to perform intermittent reciprocating arc motion to the left and right ends of the horizontal rotating arm shaft that penetrates the left and right side partition walls of the firing furnace;

  A horizontal rolling pin that is pivoted so as to be capable of rotating as a detachable operation that penetrates the side partition wall to the protruding tip of both rolling pin holding arms,

  In order to apply the dough to the rolling pin, to the dough application zone that forms the entrance side of the baking furnace, a dough dish installed so as to be movable up and down from below,

  Similarly, the arc movement trajectory is cut off in synchronization with the intermittent reciprocating arc movement of the rolling pin holding arm in order to distinguish the dough baking zone occupying the inner side of the baking furnace and the dough application zone on the inlet side. And a partition shutter that is advanced and retracted like

  While the rolling pin holding arm applies the dough from the dough plate in the dough application zone to the rolling pin, and the dough firing position of the dough firing zone that is the forward end of the movement, the partition shutter advances while stopping, While closing the dough baking zone

  Similarly, when the rolling pin holding arm performs an arc motion along its reciprocating arc motion trajectory, in the Baumkuchen baking machine that opens the dough baking zone to a communication state with the dough application zone,

Only when the rolling pin holding arm moves forward from the dough application position of the dough application zone to the dough baking position, it is also temporarily stopped at the dough preheating position of the dough baking zone, which is the forward movement intermediate point. While the dough baking zone is determined to be closed by the advancement of the partition shutter,

  Many sheathed heaters that serve as heating sources on the back of the dough baking zone are installed in parallel in an upright state,

It said a rolling pin present in the dough baking position the rolling pin is a forward end point of the holding arms, is laterally placed into between the front and rear cross-facing with its sheath heater, a far-infrared radiation panel comprising a blocking wall interposed state Rutotomoni,

Insert the sheathed heater's heating temperature detection sensor into the narrow heat storage space where the far-infrared radiation panel and the sheathed heater face each other,

The sheathed heater has a relatively low convection heat so that the dough on the rolling pin existing at the dough preheating position, which is the middle point of the forward movement of the rolling pin holding arm, does not cause raw burning or insufficient expansion during subsequent baking. Preheated by

After that, the dough on the rolling pin that has reached the dough firing position, which is the forward end of the rolling pin holding arm, is fired by the high convection heat of the sheathed heater and the radiant heat from the far infrared radiation panel,

After the baking, the rolling pin holding arm is determined so as to return quickly to the dough application position in the dough application zone without once stopping at the dough preheating position.

Further, according to claim 2, the metal pipe of each sheathed heater is bent into a substantially inverted U-shape meandering, and both lower ends thereof are inserted and fixed to a heater mounting base located at a lower position offset to the rear surface in the firing furnace. And

Furthermore, in claim 3, the far-infrared radiating panel is made of a plurality of plates made of lava, ceramics, etc., and from above to a pair of upper and lower channel grooved panel holders fixed and mounted on the left and right side partition walls of the firing furnace. It is characterized by being inserted and stood up freely.

According to the above configuration of claim 1, the electric heating type Baumkuchen baking machine can improve the problems of the prior art described at the beginning, and in addition to the electric heating type, It has the effect of preventing the lack of tightness (wetness) and softness (swelling).

In other words, while adopting a large number of sheathed heaters as a heating source, before and after the rolling pin that reaches the dough firing position, which is the forward end of the rolling pin holding arm, and the sheathed heater that fires the dough on the rolling pin Since the far-infrared radiating panel is installed as a barrier between the two, the sheath heater does not directly hit the dough on the rolling pin, and the ambient temperature in the firing furnace by the sheath heater By giving (high-temperature convection heat) and radiant heat from the far-infrared radiant panel (far-infrared rays) to the fabric in a short time, it is possible to obtain Baumkuchen that has been uniformly baked to the core of the fabric efficiently. .

In particular, the rolling pin holding arm moves not only from the dough application position in the dough application zone and the dough baking position in the dough baking zone, but also from the dough application position (forward movement start point) to the dough baking position (forward movement end point). The dough on the rolling pin held by the rolling pin holding arm is temporarily stopped at the dough preheating position of the dough baking zone, which is a moving intermediate point, and closed at the dough baking zone closed by the partition shutter during the stoppage. Since the sheathed heater is preheated for a certain period of time by the relatively low convection heat (firing furnace atmosphere temperature) of the sheathed heater, the raw burnt of the dough that is fired at the dough firing position (forward end point) after that. (Dry burn) and lack of expansion are prevented, and the expansion (soft feeling) of the dough is remarkably promoted, and the overall soft and soft baumku There is an effect obtained a hen.

Moreover, there is a far-infrared radiation panel that serves as a barrier to prevent the sheathed heater from directly hitting the dough on the rolling pin, and the sheathed heater between the front and back of the sheathed heater facing each other (heat storage space). Since the heating temperature detection sensor is installed, it is connected to the above sheathed heater in consideration of the current baking temperature measured and detected and the target baking temperature set in advance. The temperature regulator that performs the PID control of the heating power (heating temperature distribution) of the sheathed heater with high thermal efficiency is also provided.

In that case, if the structure of Claim 2 is employ | adopted, the surface area of a sheathed heater can be expanded effectively, Furthermore, the lower end which many stand up is used as a connection terminal, and it is stable to go to the heater mounting base in a firing furnace. There is an effect that can be inserted and fixed in.

Furthermore, if the configuration of claim 3 is adopted, the far-infrared radiation panel can be used as a lava plate or a ceramic plate, and far-infrared (radiant heat) can be radiated as much as possible, and it is clean without being corroded. Even if an accident such as chipping or cracking occurs during use, it can be easily replaced with a new one.

Hereinafter, the specific configuration of the present invention will be described in detail based on the illustrated embodiment. FIGS. 1 to 12 relate to a single-fired reciprocating arc motion Baumkuchen calciner, and (1) is a constant size (for example, width). Is an approximately 1,300mm x about 1,470mm height x about 750mm depth installation machine housing, with a width of about 830mm at the center, which forms a section as a firing furnace (B) Has been.

Then, either the left or right side (in the example shown, the right side as viewed from the front) parallel to the firing furnace (B) through both side partition walls (2) is a rolling pin arc motion mechanism (C) and rolling pin rotation ( A concentric storage chamber (3) with the (rotation) drive mechanism (D) is formed, and the other (the same left side in the figure) is a vacant chamber or a spare chamber (4).

However, the both sides of the machine casing (1) are divided into a pair of left and right of the storage chamber (3) of the rolling pin arc motion mechanism (C) and the storage chamber (4) of the rolling pin rotation (rotation) drive mechanism (D). May be. (5) is an operation panel installed in front of the storage room (3) and the empty room (4). The plug used for connection to the power outlet (AC200V) is not shown.

(6) is a front work port established in the center of the firing furnace (B) in the machine casing (1), and (7) is a heat exhaust duct provided directly above the front work port (6). As shown in FIG. 4, heat is exhausted from the inside of the firing furnace (B) to the upper rear outside the machine casing (1), but its lower end functions as a partition shutter receiving wall (8) described later. (9) is a front view window cut out in the exhaust heat duct (7), from which the inside of the firing furnace (B) can be seen through.

(10) is a heater mounting base fixed at a lower position offset toward the back surface in the firing furnace (B), and (11) is a large number of standing in parallel on the back surface in the firing furnace (B) (illustration example) In this case, 1.5Kw x 9) sheathed heater, the metal pipe through which the heating wire passes is bent into an almost inverted U-shape meandering to increase the surface area, as shown in FIG. The lower ends of each of the standing metal pipes are inserted into the heater mounting base (10) as connection terminals and tightened from the back side by a fixing nut (12). (13) shows an energization line connected to the sheathed heater (11).

Further, (14) is a horizontal rotating arm shaft that is horizontally mounted at a position almost directly above the front working port (6) in the firing furnace (B), and is vertical to the firing furnace (B) as shown in FIG. Both side partition walls (2) pass through, and both left and right end portions thereof are respectively supported by pillow blocks or the like inside the vacant chamber (4) and the storage chamber (3). (15) is a rotary arm shaft escape hole cut out at the upper part of both side partition walls (2).

(16) is a pair of left and right parallel rolling pin holding arms that are fitted and integrated via a boss (17) in the middle of the rotary arm shaft (14), and the storage chamber (3) and the empty chamber ( 4) and extended inside. Moreover, one rolling pin (18) is placed horizontally on the front end (rear end) where both the holding arms (16) protrude from the rotary arm shaft (14) by a certain length (L). It is designed to be detachable and replaceable.

That is, as is clear from FIGS. 6 to 8, a pillow unit (19) is attached and integrated at the tip of one of the rolling pin holding arms (16) (left side in the example), A corresponding one end (left end) of the rolling pin (18) is rotatably supported. A bearing case (20) is attached and integrated with the remaining tip (right side in the example), and the connecting sheath shaft (22) supported by the bearing (21) is moved into the storage chamber (3). A large-diameter driven sprocket (23) for rolling (spinning) of a rolling pin, which will be described later, is inserted and fitted into the shaft end portion that faces.

Similarly, the connecting head shaft (22) projects into the furnace through the side partition wall (2) of the firing furnace (B) and has a corresponding other end (right end) of the rolling pin (18). Key groove (25) that can be inserted and locked in a detachable manner so that the key pin (knock pin) (24) protruding in the radial direction from the portion is cut out in an approximately L shape or hook shape. The key pin (24) and the key The rolling pin (18) rotates (rotates) through the engagement with the groove (25). (26) is a rolling pin outlet cut out on both side partition walls (2) of the firing furnace (B), and is bent in an arc shape.

(27) is a lock pin (core shaft) penetrated into the hollow interior of the connecting sheath shaft (22), and the driven sprocket (23) is pulled out by a fixing nut (28) fastened to the screw end thereof. It is assembled in a stopped state. (29) is a compression coil spring enclosed in the hollow inside of the connecting sheath shaft (22), and the large-diameter head portion of the lock pin (27) is always placed in the direction in which the rolling pin (18) is present (inner direction of the firing furnace). The key pin (24) on the rolling pin (18) side is kept in a locked state so as not to be detached from the key groove (25) on the connecting sheath shaft (22) side.

Therefore, when attaching and using the rolling pin (18) to both holding arms (16), one end portion (left end portion) of the rolling pin (18) is first moved into the pillow unit (19) and moved. After that, the key pin (24) at the other end (right end) of the rolling pin (18) is inserted into the key groove (25) of the connecting sheath shaft (22) under the state where the lock pin (27) is pressed and locked. You can do it.

When the rolling pin (18) is removed from both holding arms (16), the key pin (24) on the rolling pin (18) side is moved to the connecting sheath shaft (22) side while the lock pin (27) is pushed in and submerged. The rolling pin (18) may be extracted from the keyway (25) and moved in the direction in which the pillow unit (19) is present. In addition, only the center part where the dough (M) is wound and applied on the rolling pin (18) is made of wood, and is formed into a cylindrical shape having a larger diameter than the left and right mounting shafts. │

The one rolling pin (18) is driven to rotate (spin) in the forward / reverse direction by its rotation (spinning) drive mechanism (D), but holds a pair of left and right rolling pins by a separate rolling pin arc motion mechanism (C). A reciprocating (up and down) arc motion is made through the arm (16) by a certain angle (for example, about 100 degrees) (θ) along the rolling pin outlet (26) around the pivot axis of the rotating arm shaft (14). You can also do that. (R) shows the arc motion locus along the escape port (26) of the rolling pin (18), and the constant length (L) of the rolling pin holding arm (16) becomes the radius of the arc motion.

The rolling pin rotation (spinning) drive mechanism (D) will now be described. The drive source is located at the mid-high position in the drive mechanism (D) storage chamber (3) as shown in FIGS. While the geared motor (30) with a brake is supported, the rotating arm shaft (14) extends into the storage chamber (3) of the rolling pin rotation (spinning) drive mechanism (D) and extends. The rolling sprockets (31) and (32) for rotating (spinning) rolling pins with different diameters are fitted and integrated in a parallel state. (33) is an endless 1 wound between the large-diameter driving sprocket (31) on the rotary arm shaft (14) and the small-diameter output sprocket (34) of the geared motor (30). The next transmission chain.

Further, the connecting sheath shaft (22), which is locked to one end (right end) of the rolling pin (18), has a shaft end facing the storage chamber (3) of the rolling pin rotation (rotation) drive mechanism (D). As described above, the large-diameter driven sprocket (23) is fitted and integrated, but the driven sprocket (23) and the small-diameter driving sprocket (32) remaining on the rotating arm shaft (14) remain. An endless secondary transmission chain (35) is wound between the two facing each other.

Therefore, the rolling pin (18) is rotated (spinned) in the forward and reverse directions by the geared motor (30) with a brake via the primary and secondary transmission chains (33) and (35). The geared motor (30) of the rotation (autorotation) drive source is inverter-controlled as the rotation speed set by the rolling pin rotation speed adjustment volume on the operation panel (5). Regarding the direction of rotation (spinning) of the rolling pin (18), the operator can perform a forward / reverse switching operation in consideration of the winding state of the dough (M) around the rolling pin (18).

On the other hand, as for the rolling pin arc motion mechanism (C), as shown in FIGS. 3 and 4, a brake motor (36) serving as a drive source in the storage chamber (3) also stores the rolling pin arc motion mechanism (C). The rolling arm shaft (14) is supported in parallel with the geared motor (30), which is a driving source for rotating (spinning) the rolling pin, and the rotating arm shaft (14) is similarly rolled to the middle height position. ) Is extended into the storage chamber (3), and a rolling sprocket (37) for rolling the rolling pin is fitted and integrated. The driven sprocket (37) on the rotating arm shaft (14) is in an installed state in parallel with the pair of rolling sprockets (31) and (32) for rotating the rolling pin (rotation).

Further, (38) is an orthogonal shaft type geared motor or speed reducer supported almost right above the brake motor (36), and a large transmission sprocket (39) on the gear shaft and the brake motor. The small output sprocket (40) of (36) is connected via an endless primary transmission chain (41), while the small diameter on the motor shaft of the orthogonal shaft type geared motor (38) is also provided. A continuous driving sprocket (42) and a rolling sprocket (37) for rolling the rolling pin on the rotating arm shaft (14) are connected by an endless secondary transmission chain (43).

Therefore, when the rotary arm shaft (14) is driven to rotate in the forward / reverse direction by the brake motor (36), the rolling pin is held backward from the rotary arm shaft (14) by a predetermined length (L). The arm (16) is circularly moved by a certain angle (θ), and one rolling pin (18) held by the holding arms (16) is a dough on the inner back side (back side) in the baking furnace (B). The firing zone (Z2) and the dough application zone (Z1) on the entrance side (front side) are also automatically reciprocated (lifted) intermittently.

In that case, the rotating arm shaft (14) penetrates the side partition wall (2) of the firing furnace (B) and extends to the inside of the empty chamber (4) (the left end portion in the example). A plurality (three in the illustrated example) of first to third strikers (cams) (44) (45) (46) are fitted and integrated in a parallel state as shown in FIGS. 1st to 3rd stop position detecting sensors (proximity switch or limit switch) (47) (48) (49) for the rolling motion of the rolling pin that can come into contact with the 1st to 3rd strikers (cam) (44) (45) (46) Is installed corresponding to the inside of the vacant chamber (4), and the rolling motion of the rolling pin every time a detection output signal is received from the first to third stop position detection sensors (47), (48), and (49). The brake motor (36) that is the drive source of the mechanism (C) is stopped. Going on.

That is, both holding arms (16) holding one rolling pin (18) are the dough application position (forward movement start point / lower limit position) (P1) of the dough application zone (Z1) in the baking furnace (B), The dough application zone (Z1) so that the dough firing zone (Z2) makes a reciprocating (up and down) arc movement by a certain angle (θ) between the dough firing position (forward end point / upper limit position) (P3) of the dough firing zone (Z2). The rolling pin holding arm (16) temporarily stops at the dough preheating position (forward movement intermediate point) (P2) of the dough baking zone (Z2) only during the forward movement (rise) from the dough to the dough baking zone (Z2). The rotating arm shaft (14) is automatically and intermittently driven by the brake motor (36) so that the rolling pin holding arm (16) is in the dough application position (P1) in the dough application zone (Z1). That stopped The dough (M) is wound and applied to the stick (18). Similarly, the rolling pin holding arm (16) is temporarily stopped at the dough preheating position (P2) of the dough baking zone (Z2). M) is preheated at a low furnace atmosphere temperature (convection heat) to prevent the dough (M) from being burned during the subsequent baking, and the degree of expansion of the dough (M) can be promoted. While (16) is also stopped at the dough baking position (P3) of the dough baking zone (Z2), the dough (M) on the rolling pin (18) is heated with high indirect resistance (convection heat) with a sheathed heater (11). By far infrared rays (radiant heat) of the far infrared radiation panel (54), it is possible to fire evenly to the center.

When the dough firing zone (Z2) moves backward (down) from the dough firing position (forward end / upper limit position) (P3) to the dough application zone (Z1), the rolling pin holding arm (16) applies the dough. Do not temporarily stop at the fabric preheating position (forward intermediate point) (P2) in the zone (Z1), but return quickly to the fabric application position (forward start point / lower limit position) (P1) in the fabric application zone (Z1). It becomes. The dough application position (P1) can be rephrased as the backward movement end point / lower limit position of the rolling pin holding arm (16).

In any case, it is a matter of course that the rolling pin (18) rotates (rotates) while the rolling pin holding arm (16) temporarily stops the reciprocating (lifting) arc motion. The stop time of the rolling pin holding arm (16) (the dough winding application time at the dough application position, the preliminary dough warming time at the dough preheating position, the dough baking time at the dough baking position) is appropriately adjusted by a timer. It can be set, and the setting can be manually canceled by a push button. The rotational speed of the brake motor (36) is also inverter controlled.

(50) is a position between the rolling pin (18) at the dough baking position (forward end point / upper limit position) (P3) of the dough baking zone (Z2) and the front and back (straight) between the sheathed heater (11). A pair of upper and lower horizontal panel holders that are fixedly mounted horizontally, and are composed of channel channel steel plates or aluminum plates facing each other, and their left and right ends are bottom support angles (51) and vertical as shown in FIGS. The pair of side support brackets (52) are attached to both side partition walls (2) of the firing furnace (B) through a pair of side support brackets (52). (53) is a fixing bolt for the attachment.

(54) is a pair of left and right far-infrared radiating panels kept in an upright state by being removably inserted into the channel groove of the panel holder (50) from above. It consists of lava, pumice, and ceramic plates that are about 400mm x height is about 250mm x thickness is about 15mm, and the multiple parallel plates block the position just before the sheathed heater (11) as shown in Figs. The dough firing position (forward end point / upper limit position) (P3) prevents the dough (M) from being dried quickly by the high temperature heating of the sheathed heater (11), and the far infrared radiation panel (54 ) From the radiant heat (far-infrared rays) to the center of the fabric (M), which can be effectively baked to give a sufficient degree of expansion and a sense of tightness (wetness).

In addition, between such a far-infrared radiating panel (54) and the sheathed heater (11) between the front and back (straight back) (heat accumulation space), the heating temperature of the sheathed heater (11) (dough baking temperature) ) A detection sensor (55) is also interposed as shown in FIGS. As an example, the temperature detection sensor (55) is composed of a radiation thermometer having a length of about 300 mm and a diameter of about 5 mm, aiming at the narrow heat storage space from the side partition wall (2) of the firing furnace (B). Hangs out almost horizontally.

A temperature regulator (not shown) connected to the sheathed heater (11) is detected by the target temperature preset by the temperature setter on the operation panel (5) and the temperature detection sensor (55). PID control of the heating power (heating temperature distribution) of the sheathed heater (11) in consideration of the current temperature thus obtained, preferably a two-degree-of-freedom PID capable of achieving both control performance of target value response and disturbance response It comes to control.

Further, (56) aims at the partition shutter receiving wall (8) suspended from the exhaust heat duct (7) of the baking furnace (B) and crosses the arc motion locus (R) of the rolling pin (18). , A pair of left and right parallel shutter shutter advancing and retreating (elevating) guide rails arranged in an upwardly inclined manner on both side partition walls (2) of the firing furnace (B), along which partition shutters (57 ) Is moved forward / backward (lifted / lowered) by a fixed stroke (S).

That is, when the partition shutter (57) is advanced (raised) so as to block the arc motion locus (R) of the rolling pin (18), the firing furnace (B) is moved as shown in FIGS. A dough application zone (Z1) on the entrance side where a dough plate described later is present, and a dough baking zone (Z2) on the inner side where the above-described sheathed heater (11), far-infrared radiation panel (54), etc. are present. Thus, the dough baking zone (Z2) can be closed at a high temperature, and heat radiation from the dough baking zone (Z2) to the dough application zone (Z1) can be prevented.

When the partition shutter (57) is retracted (lowered) as shown in FIG. 10, the dough baking zone (Z2) and the dough application zone (Z1) of the baking furnace (B) are opened to the communication state. It goes without saying that the rolling pin (18) passes between the zones (Z1) and (Z2) along the arc motion locus (R) without any trouble.

FIG. 9 shows an advancing / retreating (lifting / lowering) operation mechanism (A) of the partition shutter (57), and (58) is a geared motor with a brake serving as a dedicated drive source for the firing shutter (B). It is installed on the bottom inside.

It is connected. Moreover, a pair of pinion gears (64) are also fitted and integrated near the left and right ends of the rotary driven shaft (60), while the pair of left and right rack gears (65) meshing with these pinion gears (64) The partition shutter (57) is laid and integrated along an upwardly inclined surface. The partition shutter (57) is operated by the geared motor (58) to advance / retreat (elevate) along the advance / retreat (elevation) guide rail (56) through meshing of the rack gear (65) and the pinion gear (64). That is why.

In the illustrated embodiment, the advancing / retracting (elevating) guide rail (56) of the partition shutter (57) is made of a channel groove type steel plate or aluminum plate, and both side partition walls (2) of the firing furnace (B) are used. A plurality of rollers (66), which are attached and fixed from the inside to the side of the partition shutter (57) and supported by a pair of left and right sides, smoothly roll in the channel groove of the guide rail (56). It is supposed to be.

(67) and (68) are an advance (upward) limit position detection sensor and a backward (downward) limit position detection sensor of the partition shutter (57), both of which consist of a proximity switch or a limit switch, and a detection output from this Each time a signal is received, the geared motor (58) of the drive source is stopped. However, a pair of strikers (cams) that can come into contact with the position detection sensors (67) and (68) may be fitted and integrated in the middle of the rotary driven shaft (60).

Then, a geared motor (58) as a driving source for moving the partition shutter (57) forward / backward (lifting / lowering) and a brake motor (36) as a driving source for reciprocally moving both holding arms (16) of the rolling pin (18). Are synchronously driven to rotate intermittently, and when the rolling pin holding arm (16) moves the partition shutter (57) in a reciprocating arc motion, the dough baking zone (Z2) is kept open, and similarly the rolling pin holding arm (16) Are temporarily stopped at the dough application position (P1) of the dough application zone (Z1), the dough preheating position (P2) and the dough baking position (P3) of the dough baking zone (Z2). It can be kept closed.

Further, (69) is a dough dish containing Baumkuchen dough (M) dissolved from flour, sugar, fats, eggs, water, etc., and is a dough application zone (M) that forms the entrance side of the baking furnace (B). Z1) is horizontally mounted, and from now on, a pair of left and right support rods (70) is suspended integrally through a horizontal partition wall (table) (71). (72) is a storage chamber of the dough tray lifting and lowering operation mechanism (T) defined immediately below the partition wall (table) (71).

Moreover, the lifting / lowering operation mechanism (T) of the dough tray (69) is similar to the forward / backward (lifting / lowering) operation mechanism (A) of the partition shutter (57), and a geared motor with brake ( 73), as shown in FIGS. 1 and 4, are fixed to the bottom surface of the storage chamber (72). Similarly, (74) is a frame frame erected integrally from the bottom surface in the storage chamber (72), and has a gate shape in front view. 75) is laid horizontally.

(76) is a driving sprocket that is fitted and integrated in the central portion of the horizontal rotating intermediate shaft (75), and an output sprocket of the geared motor (73) via an endless primary transmission chain (77). (78). (79) is a pair of intermediate sprockets arranged in parallel in the vicinity of the left and right ends of the rotating intermediate shaft (75), and (80) is a horizontal rotation horizontally mounted on the upper positions of both side portions of the frame frame (74). An endless secondary transmission chain (82) is wound between the upper and lower sides of a pair of driven sprockets (81) parallel to the left and right ends of the driven shaft and the intermediate sprocket (79). Yes.

And the middle height position of the secondary transmission chain (82) and the lower end of the support rod (70) in the dough pan (69) are connected and integrated through a pair of left and right joints (83). Therefore, the dough pan (69) is moved up and down by a fixed stroke (H) through the primary and secondary transmission chains (77) and (82) by the geared motor (73) as the drive source.

In that case, the dough pan (69) existing in the dough application zone (Z1) of the baking furnace (B) temporarily stops the rolling pin holding arm (16) to the dough application position (P1) of the dough application zone (Z1). When the rolling pin is operated in synchronization with this, the dough (M) is applied to the rolling pin (18) in a wound state, coupled with the rotation (spinning) of the rolling pin (18). The rolling pin holding arm (16) is also lowered during reciprocating arc movement so as to be retracted from the arc movement locus (R) of the rolling pin (18) in synchronism with this.

Moreover, the upper limit position of the dough pan (69) can be changed appropriately with the manual rotation operation handle (84) to finely adjust the thickness of the Baumkuchen, and the thickness of the dough (M) in Baumkuchen can be adjusted. Therefore, the winding application time of the dough (M) to the rolling pin (18) can be adjusted and set by a timer.

When firing the Baumkuchen using the Baumkuchen baking machine of the present invention, if the operation preparation button on the pre-operation panel (5) is pressed, the rolling (rotation) of the rolling pin (18) is manually operated by the operator. ) And arc motion, raising and lowering of the dough pan (69), and advance and retreat (up and down) of the partition shutter (57), the setting of the dough application time, the dough preheating time and the dough baking time by the timer, and the furnace temperature setting device The dough baking temperature (in-furnace temperature) is also set by turning on the sheathing heater (11) of the heating source and closing the dough baking zone (Z2) of the baking furnace (B) by the partition shutter (57). And it is preferable to bake the rolling pin (18).

The left and right ends of the rolling pin (18) are horizontally inserted into a pair of connecting sheath shafts (22) that form the projecting front end portion (rear end portion) of the rolling pin holding arm (16) so as to be integrally rotatable. Needless to say.

After such preparation, if the dough baking temperature (furnace temperature) rises to a target set temperature (for example, about 450 ° C. to about 550 ° C.), the operation button on the operation panel (5) is also pressed, The baking operation of the dough (M) is started. Of course, the dough (M) is contained in the pre-made dough plate (69) as a dissolved state from flour, fats and oils, sugar, eggs and the like.

That is, while the rolling pin holding arm (16) is stopped at the dough application position (P1) of the dough application zone (Z1) that forms the entrance side of the baking furnace (B), The first layer of the dough (M) is applied in a wound state to the central portion of the rolling pin (18) during the rotation (spinning) motion. As an example, the atmospheric temperature while stopping at the dough application position (P1) is about 30 to 35 ° C., and the required time is about 15 to 30 seconds.

Thereafter, the partition shutter (57) of the firing furnace (B) moves backward (lowers) as shown in FIG. 10, while the rolling pin holding arm (16) moves along the arc motion trajectory (R) of the firing furnace (B). The fabric firing zone (Z2) moves forward (rises) and once stops at the fabric preheating position (P2) in the fabric firing zone (Z2) as shown in FIG. 11, the fabric firing zone (Z2) is moved to the partition shutter ( It is closed by advancement (rise) of 57).

Therefore, the dough (M) of the first layer wound around the rolling pin (18) is subjected to an ambient temperature (for example, about 150 to 200 ° C.) in the baking furnace for a preset time (for example, about 30 to 60 seconds). ) Is preliminarily warmed. The dough (M) on the rolling pin (18) is present in the dough firing zone (Z2), but is heated by so-called low indirect resistance heating (convection heat) at a position farthest from the sheathed heater (11). However, the primary firing is not performed. By being given preheating at a low ambient temperature, the so-called raw burning of the dough (M) during the subsequent baking at a high temperature and the lack of expansion (soft feeling) are prevented.

When a certain period of such preheating elapses, the rolling pin holding arm (16) continues to move (rise) to the dough baking position (P3) in the dough baking zone (Z2) as shown in FIGS. The sheathed heater (11) and the far-infrared radiation panel (54) just before it are approached. In that case, the dough baking zone (Z2) of the baking furnace (B) is still closed by the partition shutter (57).

While the rolling pin holding arm (16) is stopped at the dough baking position (P3), the first layer of dough (M) on the rolling pin (18) is also set for a predetermined time (for example, about 20 It is fired to a target set temperature (for example, about 450 to 550 ° C.) by high indirect resistance heating of the sheathed heater (11) only for ˜30 seconds). At that time, the sheathed heater (11) becomes red hot to a high temperature in a short time, but the far infrared rays that serve as a baffle plate between the sheathed heater (11) and the fabric (M) before and after (directly back). Since the radiating panel (54) is interposed, only the surface of the fabric (M) does not dry and burn, and far infrared (radiant heat) penetrates from the far infrared radiating panel (54) to the center of the fabric (M). Together, the entire fabric (M) can be baked into a uniform state rich in a tight (wet) feeling and a degree of expansion (soft feeling).

The heating temperature during the baking of the dough is measured and managed by the temperature detection sensor (55). When the preset target temperature is reached and baking of the first layer of dough (M) is completed, The partition shutter (57) of the baking furnace (B) is retracted (lowered) as shown in FIG. 10 to open the dough baking zone (Z2) to the communication state with the dough application zone (Z1), while holding the rolling pin. The arm (16) moves back (lowers) along the arc motion trajectory (R) as shown in FIGS. 12 to 10 and quickly returns to the dough application zone (Z1).

Therefore, by repeating one cycle as described above, the dough (M) in the second and subsequent layers is also sequentially fired to obtain Baumkuchen in which the dough (M) is laminated in the shape of tree rings. A product having a target thickness may be extracted from the rolling pin holding arm (16) by the operator at the front working port (6) of the installation machine casing (1).

During the baking operation for each layer of the dough (M), the partition shutter (57) of the baking furnace (B) is synchronized with the reciprocating (lifting / lowering) arc motion of the rolling pin holding arm (16), and the dough application zone (Z1 ) Is temporarily stopped at the dough application position (P1), and the operator closes the dough baking zone (Z2) of the baking furnace (B), so that the operator does not be exposed to heat radiation from the dough baking zone (Z2). Standing at the mouth (6), the dough can be replenished to the dough plate (69) and the rolling pin (18) can be attached and detached comfortably.

Similarly, the partition shutter (57) of the baking furnace (B) is synchronized with the reciprocating (lifting / lowering) arc motion of the rolling pin holding arm (16), and the dough preheating position (P2) and the dough baking position of the dough baking zone (Z2). In order to close the dough baking zone (Z2) during each stop at (P3), first the dough (M) on the rolling pin (18) at the dough preheating position (P2) is set to the atmospheric temperature in the baking furnace (relatively low temperature). Convection heat), which can easily be expanded later and can be stably preheated, and then the dough (M) on the rolling pin (18) that has reached the dough baking position (P3), and then the sheathed heater (11) is red hot. High temperature indirect resistance heating and radiant heat from far-infrared radiant panel (54) are applied in a short time to make Baumkuchen in a baked state rich in overall expansion (softness) and tightness (wetness) efficiently. can get It is.

In any case, the rolling pin holding arm (16) stopped at the dough application position (P1) of the dough application zone (Z1), the dough preheating position (P2) and the dough baking position (P3) of the dough baking zone (Z2), respectively. ) Since the upper rolling pin (18) is rotating (rotating), the dough (M) can be wound and applied to the rolling pin (18), and the dough (M) can be preheated and baked efficiently. This is useful for baking high-quality Baumkuchen.
