[0002] The invention relates to the field of food processing methods, in particular to a method for producing stone cakes by retaining traditional techniques. Background Art

[0003] Stone cake is a traditional famous snack popular in Shanxi and Shaanxi, and a traditional baked food in China. Stone cake is also called stone bun, dry cake, etc. When making stone cake, first heat the stone, and then put the kneaded white flour or grain flour directly on the stone to cook. It tastes crisp, crunchy, salty and fragrant, and is a food with a unique flavor. The existing stone cake production method is mostly traditional manual production, which retains the traditional flavor and taste of stone cake, but the production efficiency is low and the labor cost is high. Therefore, it is a problem to be solved by those skilled in the art to provide a stone cake production method with high production efficiency and the ability to retain the flavor and taste of traditional craftsmanship. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a method for producing gravel stone cakes by retaining traditional technology in view of the deficiencies in the prior art.

[0005] The technical solution of the present invention to solve the above technical problems is as follows:

[0006] The present invention provides a method for producing gravel stone cakes, comprising the following steps:

[0007] Prefabrication, including prefabrication of pie crust;

[0008] Finalizing the shape, using the stone dividing device to divide the stones into two parts, and make one of the stones fall on the conveyor belt first and be flattened by the stone paving device to form a lower stone layer, and the crust is flattened on the lower stone layer by the dough conveying mechanism, and the other stone is laid on the dough, so as to obtain a stone cake embryo with stones embedded on the upper and lower surfaces;

[0009] Baking: the stone cake embryo passes through the oven under the action of the conveyor belt and is baked under the action of the temperature in the oven to obtain a stone cake with stones embedded on the upper and lower surfaces;

[0010] Separation: Use a combination of mesh chain separation and / or tooth roller separation to separate the stones in the stone cake with stones embedded on the upper and lower surfaces from the stone cake to obtain stones and stone surface cakes respectively. The separated stones are recovered and the prefabrication step is repeated.

[0011] The beneficial effects of the present invention are: it retains the traditional process of using stones to make stone cakes, and on this basis, realizes the continuous production of stone cakes, improves the limitations of traditional manual production, improves production efficiency, and provides possibility for the wide promotion of stone cakes.

[0012] Furthermore, the separated stone cakes are first baked for a second time and then transported to the packaging equipment for packaging.

[0013] The beneficial effect of the above further scheme is that the secondary baking is conducive to the further evaporation of moisture in the stone cake, thereby extending its shelf life and increasing its crispy taste.

[0014] Furthermore, the secondary baking temperature is 100°C-250°C, and the baking time is 2-5 minutes.

[0015] The beneficial effect of the above further scheme is that the limitation of baking temperature and baking time can not only ensure that the stone cake has a better taste, but also avoid the stone cake from being burnt or over-dry or over-heated due to too long baking time or too high baking temperature.

[0016] Furthermore, the separated stones are first purified and then recycled and the stone preheating in the prefabrication step is performed again.

[0017] Furthermore, the purification process is to recycle the dust on the surface of the stones.

[0018] The beneficial effect of the above further scheme is that the purification treatment of the surface of the stone can not only ensure the hygiene of the entire production line, but also prevent the baked flour powder from sticking to the new cake crust for baking, causing blackening, burning, etc., which affects the taste and appearance of the stone cake.

[0019] Furthermore, in the baking step, the preset temperature of the oven is 100-350° C., and the baking time of the stone cake in the oven is 2-10 minutes.

[0020] The beneficial effect of the above further scheme is that the limitation of baking temperature and baking time can not only ensure that the stone cake has a better taste, but also avoid the stone cake from being burnt or over-dry or over-heated due to too long baking time or too high baking temperature.

[0021] Furthermore, the stones are spherical or quasi-spherical with a diameter of 2mm-40mm.

[0022] The beneficial effect of the above further scheme is that spherical or quasi-spherical stones are conducive to the processing of stone cakes, so that the pits formed on the stone cakes by the stones have a certain randomness and are relatively reasonably distributed, which is conducive to the formation of the unique taste of the stone cakes.

[0023] Furthermore, the stone is a solid ball, a hollow ball or a natural stone.

[0024] Furthermore, the solid ball is one of a ceramic ball, a steel ball, a glass ball, a hard alloy ball, and an alumina composite material ball, the hollow ball is a metal or non-metal hollow ball, and the natural stone is a river pebble. On this basis, the stone can also be a negative ion or functional composite ball added with rare non-metal.

[0025] The beneficial effect of the above further scheme is that it provides some specific material limitations of stones that can meet the stone cake production method. At the same time, stone here is a broad concept, which should include but not be limited to the above material limitations.

[0026] Furthermore, the crust is made of one of wheat flour, rice flour, grain flour, functional wheat flour or grain flour. On this basis, plant vegetables or dried fruit crumbs can be added to the aforementioned flour to enrich the taste of the stone cake.

[0027] The beneficial effect of the above further scheme is that the ingredients of the above cake crust are some main ingredients that conform to the traditional craftsmanship of stone cake, which can not only satisfy the traditional taste that consumers like, but also take into account the needs of nutritional matching.

[0028] Furthermore, the network chain separation is achieved by using a first stone cake separation device, which includes a frame, a driving wheel group, a separation network chain, a stone guide groove and a stone recovery bin, wherein the driving wheel group is connected to the frame and rotates under the drive of a driving motor; the separation network chain is a conveyor belt with holes, the size of the holes is between the stone and the stone cake, the separation network chain is sleeved on the driving wheel group and is driven by the rotation of the driving wheel group; the stone guide groove is a groove inclined along the axial direction, and the stone guide groove is connected to the frame and is located below the separation network chain; the stone recovery bin is connected to the frame, and the stone recovery bin is located below the lower end of the stone guide groove.

[0029] Furthermore, the tooth roller separation is achieved by using a second stone cake separation device, which includes a machine body, a separation device installed on the machine body, and a stone receiving device installed directly below the separation device. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figure 1 The present invention is a simplified flow chart of the method for producing gravel stone cakes. DETAILED DESCRIPTION

[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0032] like Figure 1 As shown, the present invention provides a method for producing stone cakes, comprising the following steps:

[0033] Prefabrication, including preheating of stones and prefabrication of crust;

[0034] Finalizing the shape, using the stone dividing device to divide the stones into two parts, and make one of the stones fall on the conveyor belt first and be flattened by the stone paving device to form a lower stone layer, and the crust is flattened on the lower stone layer by the dough conveying mechanism, and the other stone is laid on the dough, so as to obtain a stone cake embryo with stones embedded on the upper and lower surfaces;

[0035] Baking: baking the stone cake embryo with stones embedded on the upper and lower surfaces at a preset temperature to obtain a stone cake with stones embedded on the upper and lower surfaces;

[0036] Separation: Separate the stones in the stone cake with stones embedded on the upper and lower surfaces from the stone cake to obtain stones and stone surface cakes respectively. The separated stones are recovered and re-prepared, and the separated stone cakes are packaged.

[0037] Among them, in the prefabrication step, stones are placed on a conveyor belt. The stones at this time can be stones at room temperature or heated stones. At the same time, the crust is purchased or prepared in advance. At this time, it should be noted that there is no order restriction between the prefabrication of the crust and the preheating of the stones.

[0038] During the baking process, the stone cake embryo passes through the oven under the action of the conveyor belt and is baked under the action of the temperature in the oven. The preset temperature of the oven is 100-350°C. The baking time of the stone cake in the oven is 2-10 minutes, and the stone cake with stones embedded on the upper and lower surfaces is obtained;

[0039] In the separation step, a method combining mesh chain separation and toothed roller separation is used to separate stone cakes from gravel, specifically including: stone cakes with gravel embedded on the upper and lower surfaces fall from the unloading section of the conveyor belt to the first-level mesh chain separation equipment, and the gravel and stone cakes are initially separated after being shaken, and part of the gravel falls through the holes on the separation mesh chain, and the remaining gravel and stone cakes are left above the separation mesh chain. When the mesh chain separation equipment is multi-stage, the above operation is repeated until the gravel and stone cakes are completely separated, and the separated stone cakes are transported to the packaging equipment through the chain, and the collected gravel is recovered by the gravel recovery device and transported to the conveyor belt of the gravel preheating step again to realize the recycling of the gravel.

[0040] The separated stone cakes are transported to the secondary oven for secondary baking. The baking temperature is 100℃-250℃ and the baking time is 2-5min. The stone cakes after secondary baking can be transported to the packaging equipment for packaging.

[0041] The separated stones can be recovered in a dust recovery device or purified in other purification equipment, and then transported to the conveyor belt in the preheating step to repeat the stone preheating in the prefabrication step. This can make the stones cleaner and more hygienic, and avoid the problem of blackening on the surface of the processed stone cakes due to the mixing of flour powder that has not been processed before on the stones.

[0042] The stones are spherical or quasi-spherical with a diameter of 2mm-40mm.

[0043] The stone is any one of ceramic balls, steel balls, stainless steel balls, glass balls, hard alloy balls, alumina and composite material balls, negative ion or functional composite balls, metal or non-metal hollow balls, natural stones, and river pebbles.

[0044] The crust is made of wheat flour, rice flour, miscellaneous grain flour, functional wheat flour or miscellaneous grain flour, or one of the above flours with added plant vegetables.

[0045] The above preparation method can be realized by the following stone cake production line that retains traditional technology, including a gravel transport channel, a first lane, a second lane, a first lane conveyor, a second lane conveyor, an upper gravel laying mechanism, a lower gravel laying mechanism, a stone cake forming and transporting platform, and a gravel surface cake separation device.

[0046] One end of the gravel transport channel is provided with a lane dividing device which divides the gravel transport channel into a first lane and a second lane. Preferably, the lane dividing device of this embodiment is a baffle plate arranged at one end of the gravel transport channel close to the first lane conveyor and the second lane conveyor. The baffle plate divides the second half of the gravel transport channel into two branches to achieve gravel lane separation. Of course, the structure of the lane dividing device is not limited to this. Other structures that can achieve the lane dividing function (for example, directly designing the gravel transport channel as a double-branch long and short structure) are also within the protection scope of the present invention.

[0047] The two ends of the first lane conveyor are connected to the first lane and the lower stone laying mechanism respectively, and the two ends of the second lane conveyor are connected to the second lane and the upper stone laying mechanism respectively. The upper stone laying mechanism and the lower stone laying mechanism are used to lay the stones conveyed by the above-mentioned lane conveyor into the stone cake forming and baking process. Specifically, the upper stone laying mechanism and the lower stone laying mechanism both include a stone receiving trough and a stone transport device. One side of the stone receiving trough is provided with an opening for stones to leave the stone receiving trough. The lower part of the stone receiving trough is open. The stone transport device is installed at the opening at the lower part of the stone receiving trough. The stone transport device is used to transport the stones in the stone receiving trough to the opening at the lower part of the stone receiving trough. Preferably, the internal width of the stone receiving trough decreases from top to bottom to facilitate the falling of stones. The stone transport device of this embodiment can be a conveyor belt. Of course, other devices that can horizontally transport objects known in the art are also within the protection scope of the present invention.

[0048] The above structure processes the gravel in the gravel transport channel by the lane dividing device, and conveys the gravel to the upper gravel laying mechanism and the lower gravel laying mechanism respectively by the lane dividing conveyor, thereby completing the automation of gravel lane dividing and laying, greatly improving production efficiency and reducing labor costs.

[0049] The first lane conveyor and the second lane conveyor both include a conveying channel and at least one vibrator installed at the bottom of the stone channel, and the vibrator facilitates the downward movement of the stones.

[0050] At the same time, the length of the first lane is designed to be greater than that of the second lane. This design is because during the stone cake making process, the lower layer of stones needs to be laid first, then the dough cake is put in, and then the upper layer of stones is laid. Therefore, when the length of the first lane is greater than that of the second lane, it can be ensured that the lower layer of stones can be laid first on the stone cake forming and transporting platform.

[0051] The stone cake forming and transporting platform comprises a belt conveying mechanism and an oven, wherein the oven forms the baking section, and the oven and the preheated stones heat the dough cakes together, thereby greatly accelerating the maturation speed of the dough cakes.

[0052] The gravel conveying channel includes a gravel conveying belt and a plurality of conveyor belt rollers spaced apart at the bottom of the gravel conveying belt. The mesh belt structure facilitates the evaporation of moisture in the dough during baking, thereby accelerating the baking speed of the dough. Furthermore, the gravel conveying belt is supported by a plurality of conveyor belt rollers spaced apart at intervals, thereby improving the structural stability.

[0053] The separation equipment can be at least one of two types of stone cake separation equipment, namely a first stone cake separation equipment and a second stone cake separation equipment. The two separation equipment are preferably used together, which can greatly improve the separation efficiency. As shown in the figure and, the first stone cake separation equipment includes a frame, a driving wheel group, a separation network chain, a stone guide groove, and a stone recovery bin. The driving wheel group is connected to the frame and rotates under the drive of the driving motor; the separation network chain is a conveyor belt with holes, and the size of the holes is between the stone and the stone cake. The separation network chain is sleeved on the driving wheel group and is driven by the rotation of the driving wheel group; the stone guide groove is a groove inclined along the axial direction, and the stone guide groove is connected to the frame and is located below the separation network chain; the stone recovery bin is connected to the frame, and the stone recovery bin is located below the lower end of the stone guide groove. The separation equipment is arranged below the unloading end of the gravel cake conveyor belt. The setting of the height difference makes the separation steps of gravel cake and gravel include throwing out, falling, knocking and leaking. The size and shape of the holes on the separation net chain are suitable for the falling of matching gravel and can ensure that the gravel cake remains on the separation net chain and is transmitted to the next process.

[0054] The separation network chain comprises a first separation network segment and a second separation network segment, the projections of the first separation network segment and the second separation network segment on the horizontal plane overlap, and the overlapping parts have a height difference on the vertical plane, that is, the first separation network segment and the second separation network segment are in a reverse "z" shape. The driving wheel group is a group, including a steering wheel and a positioning wheel, the separation network chain is a closed ring network chain sleeved on the driving wheel group, the positioning wheels are at least four, two of which are respectively connected to the two sides of the upper part of the frame, and are used to position the upper side of the closed ring network chain, and the remaining positioning wheels are also connected to the frame, and are used to position the separation network chain into a tight closed ring network chain, so as to facilitate the operation of the separation network chain, at least one of the positioning wheels is connected to the motor, and the steering wheels are two, which are respectively the first steering wheel and the second steering wheel along the transmission direction of the separation network chain, the height of the first steering wheel is higher than the height of the second steering wheel, and the first steering wheel and the second steering wheel separate the upper side of the separation network chain into the first separation network segment and the second separation network segment with a height difference. When the first separation net chain segment and the second separation net chain segment are located on the same closed separation net chain, a larger closed cavity will be formed inside the separation net chain. The gravel guide groove and the gravel recovery bin can be located in such a closed cavity, which can facilitate the installation and arrangement of the equipment and save space.

[0055] The second stone and flour cake separation equipment includes a body, a separation device installed on the body, and a stone receiving device installed directly below the separation device. The separation device can be a single-stage separation mechanism composed of a screen and a toothed roller group, or a two-stage separation mechanism as shown in the figure that can bring better separation effect. The two-stage separation mechanism includes an upper screen, an upper toothed roller group, a lower screen and a lower toothed roller group. The meshes of the upper screen and the lower screen are larger than the stone size and smaller than the flour cake size. The upper screen is installed on the upper toothed roller group, and the lower screen is installed on the lower toothed roller group. The upper toothed roller group and the lower toothed roller group are respectively located at the front and rear sides of the body, that is, the flour cake transported by the upper screen and the stones that are not completely filtered out are connected by the lower screen and screened out for the second time. The upper toothed roller group and the lower toothed roller group both include a plurality of parallel toothed rollers made of stainless steel. The toothed rollers are connected to a toothed roller driving device, and the driving device can be a driving motor or other mechanism.

[0056] It should be noted that the "upper and lower" in the above-mentioned upper screen, upper gear roller group, lower screen and lower gear roller group refer to the relative upper and lower position relationship of the upper screen and the lower screen or the upper gear roller group and the lower gear roller group, and do not refer to the position of the above-mentioned structures on the machine body.

[0057] Specifically, the toothed roller of this embodiment is provided with multiple rows of tooth groups evenly spaced along its circumference, and each row of tooth groups has multiple teeth evenly spaced along the axial direction of the toothed roller. The screen is provided with mesh holes for the teeth of the toothed roller to pass through, that is, when the toothed roller rotates, any row of teeth can pass through the mesh holes of the screen, and can also play a certain role in moving the cakes. The multiple teeth of the toothed roller are designed to be evenly spaced, which can ensure the regularity of the movement of stones and stone cakes and avoid uneven filtering of stones. Of course, there can be many ways to arrange the teeth on the toothed roller group, for example, multiple teeth can be unevenly distributed, or the size and shape of the teeth can be modified. Conventional improvements made by those skilled in the art to the arrangement and shape of the teeth are also within the protection scope of the present invention.

[0058] The stone paving equipment for leveling the lower stone, the stone paving equipment includes a stone leveling mechanism located above the stone cake forming and transporting platform and a vibration mechanism located below the stone cake forming and transporting platform, the distance between the bottom of the stone leveling mechanism and the upper surface of the stone cake forming and transporting platform is greater than or equal to the particle size of the stone and less than twice the particle size of the stone. It should be noted that the sizes of the above-mentioned stones in this embodiment are roughly the same or completely the same, and are prefabricated by the applicant. The vibration part of the vibration mechanism in this embodiment contacts the bottom of the stone cake forming and transporting platform, and transmits the vibration to the stone cake forming and transporting platform.

[0059] Specifically, the stone leveling mechanism of the present embodiment includes a plurality of leveling rollers spaced apart along the stone transport direction. More specifically, there are two leveling rollers, one of which is located directly above the vibration mechanism, and the other is disposed on the middle and rear sections of the stone cake forming and transporting platform. The stone can be initially leveled during the vibration stage, and secondary leveled by the leveling rollers on the middle and rear sections of the stone cake forming and transporting platform, thereby improving the leveling effect.

[0060] Specifically, the vibration mechanism of this embodiment includes a bracket, an elastic member and a vibration motor, the bottom of the vibration motor is installed on the bracket, the vibration mechanism on the upper part of the vibration motor is in contact with the stone cake forming and transporting platform, one end of the elastic member is connected to the upper part of the vibration motor, and the other end is installed on the bracket, the vibration mechanism on the upper part of the vibration motor is reset by the elastic member during the vibration process, and the elastic member can play a certain buffering role on the vibration of the vibration motor. Preferably, the top of the vibration motor of this embodiment is provided with a plurality of rollers, and the rollers are connected to the bottom of the stone cake forming and transporting platform. Since the vibration motor will generate a certain horizontal displacement vibration in addition to the reciprocating vibration up and down, in order to avoid the horizontal vibration from affecting the upper stone forming and transporting platform, the top of the vibration motor of this embodiment is provided with rollers, and the rotation of the rollers can avoid the horizontal vibration from disturbing the upper stone cake forming and transporting platform. More preferably, the elastic member of this embodiment is a spring, and the four springs are respectively installed on the left and right sides of the bracket, and the spring has a good restoring effect and shock absorption ability.

[0061] Specifically, in this embodiment, in order to further improve the baking efficiency, this embodiment is also provided with a secondary baking device which is connected to the stone cake separation device and bakes the cake for the second time, so as to further bake the cake and prevent some areas of the cake from being not fully cooked after being baked once.

[0062] It also includes a stone circulation transport device for transporting stones screened out by the stone cake separation device to the stone transport channel, one end of the stone circulation transport device is connected to the stone cake separation device, and the other end is connected to the stone transport channel. The stone circulation transport device can greatly improve the utilization rate of stones, and because the stones just separated from the cake have a certain residual temperature, the heat energy required to heat the stones can be reduced after entering the preheating section again, saving energy.

[0063] There are many ways to arrange the stone cake forming and transporting platform and the gravel transporting channel. For example, the stone cake forming and transporting platform and the gravel transporting channel are arranged on the same horizontal plane, or have a certain height difference. In this case, the gravel circulation and transporting device structure can also be composed of a gravel conveyor belt and conveyor belt rollers. For another example, the stone cake forming and transporting platform is arranged below the gravel transporting channel. In this case, the gravel circulation and transporting device can be a structure such as a vertical hoist to vertically transport the gravel into the gravel transporting channel. Of course, other arrangement structures are also within the protection scope of the present invention.

[0064] A powder recovery and filtering device is provided between the stone transport channel and the stone circulation device. The powder recovery and filtering device may be a negative pressure exhaust fan or the like, which is used to remove powder from the recycled stones to prevent the powder from affecting the dough when the stones are put back into production.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
