Description

Technical Field

[0001] The present invention relates to the technical field of candy preparation, and specifically, to a candy preparation device and preparation method containing rose petals. Background Art

[0002] Candy is a delicate and preservable sweet solid food with different physical states, textures and flavors, which is mainly composed of granulated sugar and starch syrup, boiled, and mixed with some food additives through processes such as blending, cooling and forming.

[0003] At present, syrup is required for candy processing. Most of the existing syrups are made by boiling sugar water raw materials. When processing candies, the sugar water raw materials need to be poured into the preparation device first, and syrup is made through operations such as heating and stirring. However, after the existing preparation device boils the syrup, the syrup needs to be cooled down for subsequent processing procedures.

[0004] For example, a syrup boiling machine disclosed in the patent with the publication number CN218418282U can facilitate the pouring out of materials by the rotation of an arc-shaped scraper and can scrape the materials on the inner wall of the boiling furnace at the same time. However, in actual use, the syrup boiled in the boiling furnace is directly poured into the discharge frame. Since the temperature of the syrup is relatively high, it is easy to splash and scald the staff. Therefore, the syrup needs to be cooled down for subsequent processing procedures.

Specific embodiments

[0035] To further understand the content of the present invention, the present invention will be described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention and not for limiting it.

[0036] The following will be further described in detail with reference to the attached Figures 1-8 This embodiment will be further described in detail.

[0037] As Figures 1-2As shown in the figure, a candy preparation device containing rose petals in this embodiment is used for boiling syrup, and includes a tank body 100 and a tank cover 110. A stirring assembly is provided inside the tank body 100. A heating cover 200 is covered at the bottom of the tank body 100, and a heating assembly for heating the syrup inside the tank body 100 is provided inside the heating cover 200. A cooling cover 120 is also covered outside the tank body 100, and a cooling assembly for cooling the syrup inside the tank body 100 is provided inside the cooling cover 120. A turbulizing assembly for turbulizing the syrup inside the tank body 100 when the syrup is cooled is also provided on the stirring assembly. A control member for switching the working state of the turbulizing assembly is provided on the tank cover 110.

[0038] In actual use of this embodiment, the upper end of the tank body 100 is open. By adding sugar water raw materials into the tank body 100 from the opening, the heating assembly is used to heat the sugar water raw materials inside the tank body 100 to boil the sugar water raw materials inside the tank body 100 to prepare syrup.

[0039] Among them, the heating cover 200 is fixedly installed at the bottom of the tank body 100 for installing the heating assembly inside it. Among them, the heating assembly includes heating wires (not shown in the figure) arranged along the circumferential direction of the tank body 100 on the bottom wall of the tank body 100. The sugar water raw materials inside the tank body 100 can be preferably boiled through the heating wires.

[0040] Among them, in order to make the concentration of the boiled syrup uniform, a stirring assembly is provided inside the tank body 100. The stirring assembly is used to gently stir and mix the sugar water raw materials inside the tank body 100 when boiling the sugar water raw materials, which is preferably convenient for boiling the syrup.

[0041] In actual use of this embodiment, a lapping portion extends outward from the upper end of the tank body 100, and the tank cover 110 is fixedly installed on the lapping portion through bolts to install the tank cover 110 at the opening of the tank body 100, that is, it is convenient for subsequent installation of the stirring assembly and the control member on the tank body 100.

[0042] Among them, in combination with Figure 5 As shown in the figure, the stirring assembly includes a stirring shaft 240 rotatably arranged inside the tank body 100. The upper end of the stirring shaft 240 extends through the tank cover 110 and protrudes. The lower end of the stirring shaft 240 passes through the heating cover 200 and is connected to a motor 241 fixedly arranged below the heating cover 200. The motor 241 can drive the stirring shaft 240 to rotate. Among them, stirring rods 501 are evenly distributed on the stirring shaft 240. By driving the stirring rods 501 to rotate through the stirring shaft 240, the sugar water raw materials inside the tank body 100 are stirred and mixed.

[0043] In this embodiment, a cooling cover 120 is placed outside the tank body 100, which can preferably keep the tank body 100 warm during the boiling of the sugar water raw material in the tank body 100 to reduce the heat dissipation during boiling. At the same time, through the setting of the cooling component, the cooling component can quickly cool down the syrup after boiling so that the syrup can enter the next process;

[0044] Among them, through the setting of the stirring flow component, when the cooling component is working, the stirring flow component can cooperate with the working of the stirring component to make the syrup boiled in the tank body 100 generate turbulence, so as to improve the cooling effect of the cooling component;

[0045] It should be noted that during the boiling of the sugar water raw material, since the concentration of the sugar water raw material is low and during the boiling process, it is necessary to avoid violent stirring that may cause more bubbles in the boiled sugar water raw material and affect the quality of the subsequent syrup. When the preparation device boils the syrup, the stirring flow component does not work, and only the stirring component gently stirs the sugar water raw material. When cooling down the syrup, since the concentration of the syrup is higher than that of the sugar water raw material and the syrup is relatively viscous, at this time, the stirring flow component and the stirring component need to work synchronously to increase the turbulence of the syrup in the tank body 100, thereby improving the effect of the cooling component to quickly cool down the syrup;

[0046] Among them, through the setting of the control part, it can preferably control the stirring flow component so as to switch whether the stirring component drives the stirring flow component to work, that is, to switch the working of the stirring flow component;

[0047] When this embodiment is actually used, in order to discharge the syrup in the tank body 100 after cooling, a discharge pipe 101 is provided at the bottom wall of the tank body 100 and extends through the heating cover 200. Therefore, in order to install the motor 241 and the discharge pipe 101, support legs 102 for supporting them are provided on the bottom wall of the tank body 100.

[0048] Combined with Figures 3-4 As shown, in this embodiment, the cooling component includes a heat conduction ring 210 arranged circumferentially in the tank body 100 along the circumferential direction of the tank body 100. A plurality of heat conduction rings 210 are uniformly arranged along the axial direction of the tank body 100. A flow channel 211 communicating with the inside of the cooling cover 120 is arranged along the circumferential direction inside the heat conduction ring 210. A guide plate 221 extending into the corresponding flow channel 211 is arranged inside the cooling cover 120;

[0049] The cooling component further includes a plurality of coolant inlet pipes 301 uniformly arranged above the cooling cover 120 and a coolant discharge pipe 302 arranged below the cooling cover 120 corresponding to the coolant inlet pipes 301. A circulation pump for driving the circulation of the coolant is arranged between the coolant inlet pipe 301 and the coolant discharge pipe 302.

[0050] In actual use of this embodiment, a flow loop of the coolant is formed among the corresponding coolant inlet pipe 301, coolant outlet pipe 302 and a circulation pump (not shown in the figure). Thus, the coolant enters the cooling cover 120 from above the cooling cover 120. Among them, through the settings of the heat conduction ring 210, the flow channel 211 and the guide plate 221, the guide plate 221 extends into the flow channel 211, separating the flow channel 211 into an upper flow channel and a lower flow channel that are connected to each other. Thus, the coolant entering the cooling cover 120 can flow through the corresponding heat conduction ring 210 from top to bottom in sequence. Since the heat conduction ring 210 extends into the tank body 100 to contact the syrup and is made of a heat-conducting material, the coolant flowing in the cooling cover 120 can absorb the heat in the syrup, thereby achieving rapid cooling of the syrup.

[0051] In actual use, a radiator 130 is connected in the flow loop formed among the corresponding coolant inlet pipe 301, coolant outlet pipe 302 and the circulation pump. The radiator 130 adopts an existing structure. Thus, the heat entering the flow loop is dissipated, and further, it is ensured that the temperature of the coolant entering the cooling cover 120 is relatively low, thereby ensuring the effect of the coolant in cooling the syrup.

[0052] In this embodiment, since the cooling cover 120 is cylindrically arranged, the coolant entering the cooling cover 120 from the coolant inlet pipe 301 flows through the flow channel 211 from top to bottom in sequence to exchange heat and cool the syrup in the tank body 100. By adopting this method, there are blind spots in the flow of the coolant in the cooling cover 120, that is, the heat exchange and cooling of the syrup in the tank body 100 are uneven. Therefore, a plurality of flow loops formed among the coolant inlet pipe 301, coolant outlet pipe 302 and the circulation pump are arranged along the circumferential direction of the cooling cover, so that the coolant can flow through the heat conduction ring 210 more evenly.

[0053] In this embodiment, a rotatable coolant storage ring 230 is arranged above the cooling cover 120. A storage cavity 401 for storing the coolant discharged from the coolant inlet pipe 301 is arranged in the coolant storage ring 230. Leakage holes 402 are uniformly arranged on the bottom wall of the storage cavity 401.

[0054] In actual use of this embodiment, a lap joint ring is arranged along the circumferential direction in the cooling cover 120, and the coolant storage ring 230 is lapped on the lap joint ring to realize its rotational installation in the cooling cover 120.

[0055] Among them, the coolant entering the cooling cover 120 through the coolant inlet pipe 301 can enter the coolant storage ring 230 for temporary storage. By using the uniformly arranged liquid leakage holes 402, the coolant entering the coolant storage ring 230 can be evenly sprayed into the cooling cover 120 under the rotation of the coolant storage ring 230, so that the coolant can flow through the flow channel 211 more evenly, that is, it can avoid the flow blind area of the coolant flowing in the cooling cover 120, thus preferably ensuring the uniformity of heat exchange and cooling of the syrup in the tank body 100.

[0056] In this embodiment, a sliding groove 303 is provided along the circumferential direction of the upper end surface of the cooling cover 120. A shift lever 231 extending through the sliding groove 303 is provided on the coolant storage ring 230. A driving plate 290 is provided at the upper end of the stirring shaft 240, and a driving rod sleeved on the corresponding shift lever 231 is provided on the driving plate 290.

[0057] In actual use of this embodiment, an installation step is formed at the upper end of the stirring shaft 240. The driving plate 290 is fixedly installed on the installation step by a nut. Thus, the driving plate 290 is fixedly installed on the stirring shaft 240, so that the rotation of the stirring shaft 240 can drive the driving plate 290 to rotate, and then drive the shift lever 231 to slide along the sliding groove 303 through the driving rod, so that the coolant storage ring 230 is rotatably installed in the cooling cover 120.

[0058] Combined Figure 2 and Figure 5 As shown in the figure, in this embodiment, the heat conduction ring 210 is uniformly provided with notch openings 311 for the bubbles in the syrup to move upward. A scraping plate 502 extending between adjacent heat conduction rings 210 and fitting the inner wall of the tank body 100 is provided on the stirring rod 501.

[0059] In actual use of this embodiment, since bubbles will be generated during the boiling of the sugar water raw material, in order to prevent the heat conduction ring 210 from blocking the rising of the bubbles and affecting the quality of the syrup due to the presence of bubbles in the syrup. Among them, through the arrangement of the notch openings 311 and the scraping plate 502, when the stirring shaft 240 drives the stirring rod 501 to stir, it can drive the scraping plate 502 to rotate between adjacent heat conduction rings 210, and then drive the bubbles to move, so that the bubbles can move upward and be discharged through the notch openings 311. At the same time, the scraping plate 502 scrapes along the inner side wall of the tank body 100, which can preferably prevent the syrup from adhering to the tank wall and causing scorching during boiling.

[0060] Combined Figures 5-7 As shown in the figure, in this embodiment, the flow stirring assembly includes a flow stirring plate 250 sleeved on the corresponding stirring rod 501. Both ends of the flow stirring plate 250 are provided on the stirring shaft 240 through tension springs 260. The tension springs 260 are used to drive the flow stirring plate 250 to move towards the stirring shaft 240. A guide rod 511 is provided at the upper end of the flow stirring plate 250;

[0061] The control member includes a pressure plate 270 sleeved on the stirring shaft 240 and capable of lifting. A convex plate 610 is coaxially provided on the lower plate surface of the pressure plate 270. A groove 611 for the corresponding guide rod 511 to extend into is provided on the convex plate 610 corresponding to the guide rod 511. Guide inclined surfaces 612 are formed on both side walls of the groove 611. The stirring flow plate 250 rotates to drive the guide rod 511 to slide out of or into the groove 611 along the guide inclined surfaces 612, so as to realize the reciprocating movement of the stirring flow plate 250 along the stirring rod 501.

[0062] During actual use of this embodiment, a convex platform ring for limiting the stirring flow plate 250 is sleeved outside the stirring rod 501, so that the distance that the stirring flow plate 250 moves along the stirring rod 501 towards the stirring shaft 240 under the action of the tension spring 260 is limited, that is, the stirring flow plate 250 is slidably installed on the stirring rod 501;

[0063] Among them, through the settings of the pressure plate 270, the convex plate 610, the groove 611 and the guide inclined surfaces 612, when the pressure plate 270 descends and the guide rod 511 extends into the corresponding groove 611, at this time, the stirring rod 501 rotates to drive the stirring flow plate 250 to rotate circumferentially along the stirring shaft 240, so that the guide rod 511 slides out of or into the groove 611 along the guide inclined surfaces 612. Furthermore, while the stirring rod 501 drives the stirring flow plate 250 to rotate, the stirring flow plate 250 reciprocates along the stirring rod 501, which can preferably drive the syrup in the tank body 100 to generate turbulence, so that the syrup contacts the heat conduction ring 210 more evenly for heat exchange and cooling, thereby improving the cooling effect of the cooling assembly; when the pressure plate 270 moves upward, the guide rod 511 can be separated from the corresponding groove 611. At this time, the stirring flow plate 250 will not reciprocate on the stirring rod 501 as the stirring rod 501 rotates, that is, the stirring flow assembly does not work.

[0064] Among them, in order to preferably realize that when the pressure plate 270 moves downward, the guide rod 511 can extend into the corresponding groove 611, a guide ring 620 is coaxially provided on the lower end surface of the convex plate 610. A guide surface 621 for guiding the guide rod 511 into the groove 611 is provided on the outer side wall of the guide ring 620. By using the settings of the guide ring 620 and the guide surface 621, when the pressure plate 270 moves downward, the guide rod 511 can be made to fit the convex plate 610 and slide into the corresponding groove 611 by using the setting of the guide surface 621, so as to facilitate the operation of the stirring flow assembly.

[0065] In this embodiment, the control member further includes a mounting cylinder 280 provided on the can lid 110 and sleeved outside the stirring shaft 240. Sliders 711 are oppositely provided on the inner side wall of the mounting cylinder 280 along its axial direction. The upper end of the pressure plate 270 is provided with a fixing cylinder 630 sleeved outside the stirring shaft 240 and extending through the mounting cylinder 280. A sliding groove 631 for the corresponding slider 711 to slide is provided on the outer side wall of the fixing cylinder 630. A spring 271 for driving the pressure plate 270 to move downward is sleeved outside the fixing cylinder 630 located inside the tank body 100. Mounting grooves 632 are oppositely provided on the outer side wall of the fixing cylinder 630. A locking sliding groove 633 is provided on the bottom wall of the mounting groove 632. The locking sliding groove 633 includes an upper positioning portion and a lower positioning portion. A rotatable locking rod 640 is provided inside the mounting cylinder 280. One end of the locking rod 640 is provided with a sliding rod 721 sliding in the locking sliding groove 633. When the sliding rod 721 slides to the upper positioning portion and the lower positioning portion, it is used for lifting and lowering the pressure plate 270 to realize the state switching of the stirring flow component.

[0066] In this embodiment, the lower end of the mounting cylinder 280 extends outward to form a mounting portion 712, and the mounting portion 712 is fixedly mounted on the can lid 110 by screws;

[0067] Among them, by the cooperative setting of the sliding groove 631 and the slider 711, a keyway fit is formed between the fixing cylinder 630 and the mounting cylinder 280, so that the pressure plate 270 can be lifted and lowered and mounted on the can lid 110 and cannot rotate circumferentially;

[0068] Among them, in combination with Figure 8As shown, the locking chute 633 is a polygonal groove, which includes an upper concave portion 801 and a lower concave portion 802. First bending grooves 803 and second bending grooves 804 are respectively formed on both sides of the upper concave portion 801 and the lower concave portion 802. A first inclined surface 805 opposite to the upper concave portion 801 and a second inclined surface 806 opposite to the lower concave portion 802 are provided at the first bending groove 803. A third inclined surface 807 opposite to the lower concave portion 802 is provided at the second bending groove 804. During actual use, one end of the locking rod 640 forms a sliding rod 721 that slides within the locking chute 633, and the other end forms a mounting rod 722 that is rotatably mounted on the mounting cylinder 280. The pressing plate 270 is always pushed downward by the spring 271, driving the fixed cylinder 630 to move downward. Among them, the upper concave portion 801 forms an upper positioning portion, and the lower concave portion 802 forms a lower positioning portion. When the sliding rod 721 is within the upper concave portion 801, at this time, the pressing plate 270 is in a downward moving state, that is, its downward movement can make the guide rod 511 extend into the groove 611 to realize the operation of the flow stirring assembly. At this time, lifting the fixed cylinder 630 makes the sliding rod 721 slide into the first bending groove 803 under the guiding action of the first inclined surface 805, and under the guiding action of the second inclined surface 806, the sliding rod 721 slides into the lower concave portion 802. At this time, releasing the fixed cylinder 630 makes it, under the action of the spring 271, the pressing plate 270 is in an upward moving state, that is, the guide rod 511 is separated from the groove 611. At this time, by lifting and releasing the fixed cylinder 630 again, the sliding rod 721 can slide along the second bending groove 804 to the upper concave portion 801 under the action of the third inclined surface 807. In this way, the sliding of the sliding rod 721 within the locking chute 633 is realized, and the switching of whether the flow stirring assembly works is carried out;

[0069] Among them, in order to facilitate the operator to lift the fixed cylinder 630, a pressing ring 634 is provided at the upper end of the fixed cylinder 630.

[0070] The present invention also provides a method for preparing a candy containing rose petals, which specifically includes the following steps:

[0071] S1. Add the sugar water raw material into the tank body 100, start the heating assembly. At the same time, drive the flow stirring assembly to move upward through the control member.
