Description

Candy preparation device and preparation method containing rose petals

Technical Field

The invention relates to the technical field of candy preparation, in particular to a device and method for preparing candy containing rose petals.

Background technique

Candy is made mainly of sugar and starch syrup, which is boiled and added with some food additives. It goes through blending, cooling, molding and other process operations to form a delicate and long-lasting sweet solid food with different physical states, textures and aromas.

At present, candy processing requires the use of syrup, and most of the existing syrups are made by boiling sugar water raw materials. When processing candy, the sugar water raw materials need to be poured into a preparation device first, and the syrup is made through heating, stirring and other operations.

In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

The present embodiment will be further described in detail below in conjunction with Figures 1 to 8.

As shown in Fig. 1-2, a candy preparation device containing rose petals in the present embodiment is used for boiling syrup, and comprises a tank body 100 and a tank cover 110. A stirring assembly is provided in the tank body 100. A heating cover 200 is provided at the bottom of the tank body 100. A heating assembly for heating the syrup in the tank body 100 is provided in the heating cover 200. A cooling cover 120 is also provided outside the tank body 100. A cooling assembly for cooling the syrup in the tank body 100 is provided in the cooling cover 120. A stirring assembly for stirring the syrup in the tank body 100 when the temperature is reduced is also provided on the stirring assembly. A control component for switching the working state of the stirring assembly is provided on the tank cover 110.

In actual use of this embodiment, the upper end of the tank body 100 is opened, and the sugar water raw materials are added into the tank body 100 through the opening, and the sugar water raw materials in the tank body 100 are heated by the heating component to achieve boiling of the sugar water raw materials in the tank body 100 to prepare syrup;

The heating cover 200 is fixedly installed at the bottom of the tank body 100, and is used to install a heating component therein, wherein the heating component includes a heating wire (not shown in the figure) arranged on the bottom wall of the tank body 100 along the circumference of the tank body 100, and the sugar water raw materials in the tank body 100 can be boiled preferably by the heating wire;

In order to make the concentration of the boiled syrup uniform, a stirring component is provided in the tank body 100, and the stirring component is used to gently stir and mix the syrup raw materials in the tank body 100 when boiling the syrup raw materials, so as to facilitate the boiling of the syrup;

In actual use of this embodiment, the upper end of the tank body 100 extends outward to form an overlap portion, and the tank cover 110 is fixedly installed on the overlap portion by bolts, so as to realize the installation of the tank cover 110 at the opening of the tank body 100, that is, to facilitate the subsequent installation of the stirring assembly and the control component on the tank body 100;

5, the stirring assembly includes a stirring shaft 240 rotatably arranged in the tank body 100, the upper end of the stirring shaft 240 penetrates the tank cover 110 and extends out, the lower end of the stirring shaft 240 penetrates the heating cover 200 and is connected to a motor 241 fixedly arranged below the heating cover 200, and the stirring shaft 240 can be driven to rotate by the motor 241, wherein stirring rods 501 are evenly distributed on the stirring shaft 240, and the stirring rods 501 are driven to rotate by the stirring shaft 240 to achieve stirring and mixing of the syrup raw materials in the tank body 100;

In this embodiment, the cooling cover 120 is covered outside the tank body 100, which can better keep the tank body 100 warm when the sugar water raw material is boiled in the tank body 100 to reduce the heat loss during boiling; at the same time, through the setting of the cooling component, the cooling component can quickly cool the syrup after boiling so that the syrup can enter the next process;

Among them, by setting the stirring component, the stirring component can cooperate with the stirring component when the cooling component is working, so that the syrup boiled in the tank body 100 can generate turbulence, so as to improve the cooling effect of the cooling component;

It should be pointed out that when boiling the syrup raw material, since the concentration of the syrup raw material is low and during the boiling process, it is necessary to avoid violent stirring to cause more bubbles to be generated in the boiled syrup raw material, which affects the quality of the subsequent syrup. Therefore, when the preparation device is boiling the syrup, the stirring component does not work, and only relies on the stirring component to stir the syrup raw material more gently; when cooling the syrup, since the concentration of the syrup is higher than that of the syrup raw material and the syrup is more viscous, at this time, the stirring 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 on the rapid cooling of the syrup;

Among them, through the setting of the control component, it is possible to better control the flow stirring component, so as to determine whether the stirring component drives the flow stirring component to work, that is, to switch the flow stirring component to work;

In actual use of this embodiment, in order to discharge the syrup after the tank body 100 is cooled, a discharge pipe 101 extending through the heating cover 200 is provided at the bottom wall of the tank body 100. Therefore, in order to install the motor 241 and the discharge pipe 101, a support leg 102 for supporting them is provided on the bottom wall of the tank body 100.

As shown in FIGS. 3-4 , in this embodiment, the cooling assembly includes a heat conducting ring 210 disposed in the tank body 100 along the circumferential direction of the tank body 100, a plurality of heat conducting rings 210 are evenly arranged along the axial direction of the tank body 100, a flow channel 211 connected to the cooling cover 120 is disposed in the heat conducting ring 210 along its circumferential direction, and a guide plate 221 extending into the corresponding flow channel 211 is disposed in the cooling cover 120;

The cooling assembly also includes a plurality of coolant inlet pipes 301 evenly arranged above the cooling cover 120 and coolant outlet pipes 302 corresponding to the coolant inlet pipes 301 arranged below the cooling cover 120. A circulation pump for driving the circulation of the coolant is provided between the coolant inlet pipes 301 and the coolant outlet pipes 302.

In actual use of this embodiment, a flow loop of the coolant is formed between the corresponding coolant inlet pipe 301, the coolant outlet pipe 302 and the circulating pump (not shown in the figure), thereby allowing the coolant to enter the cooling cover 120 from the top of the cooling cover 120; wherein, by providing the heat-conducting ring 210, the flow channel 211 and the guide plate 221, the guide plate 221 extends out of the flow channel 211, and the flow channel 211 is divided into an upper flow channel and a lower flow channel that are interconnected, thereby allowing the coolant entering the cooling cover 120 to flow through the corresponding heat-conducting ring 210 from top to bottom in sequence, and since the heat-conducting 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;

In actual use, the corresponding coolant inlet pipe 301, the coolant outlet pipe 302 and the flow loop formed by the circulating pump are connected with a radiator 130, and the radiator 130 adopts an existing structure, thereby dissipating the heat entering the flow loop, thereby ensuring that the temperature of the coolant entering the cooling cover 120 is low, thereby ensuring the effect of the coolant cooling the syrup;

In this embodiment, since the cooling hood 120 is arranged in a cylindrical shape, the coolant entering the cooling hood 120 through the coolant inlet pipe 301 flows through the flow channel 211 from top to bottom in sequence, and the syrup in the tank body 100 is heat exchanged and cooled. In this way, there is a blind spot in the flow of the coolant in the cooling hood 120, that is, the heat exchange and cooling of the syrup in the tank body 100 is uneven. Therefore, a plurality of flow loops formed by the coolant inlet pipe 301, the coolant discharge pipe 302 and the circulating pump are arranged along the circumference of the cooling hood to allow the coolant to flow through the heat conductive ring 210 more evenly.

In this embodiment, a rotatable coolant storage ring 230 is provided inside and above the cooling cover 120, and a storage cavity 401 for storing coolant discharged from the coolant inlet pipe 301 is provided inside the coolant storage ring 230, and leakage holes 402 are evenly distributed on the bottom wall of the storage cavity 401.

In actual use of this embodiment, a lap ring is provided inside the cooling cover 120 along its circumference, and the coolant storage ring 230 is overlapped on the lap ring, so as to realize its rotational installation inside the cooling cover 120;

Among them, the coolant entering the cooling hood 120 through the coolant inlet pipe 301 can enter the coolant storage ring 230 for temporary storage, and the evenly arranged leakage holes 402 are used to allow the coolant entering the coolant storage ring 230 to be more evenly poured into the cooling hood 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 existence of a flow blind spot for the coolant flowing in the cooling hood 120, thereby better ensuring the uniformity of heat exchange and cooling of the syrup in the tank body 100.

In this embodiment, a sliding groove 303 is provided on the upper end surface of the cooling cover 120 along its circumference, a lever 231 extending through the sliding groove 303 is provided on the coolant storage ring 230, a driving plate 290 is provided on the upper end of the stirring shaft 240, and a driving rod which is sleeved on the corresponding lever 231 is provided on the driving plate 290.

During actual use of this embodiment, a mounting step is formed at the upper end of the stirring shaft 240, and the driving plate 290 is fixedly mounted on the mounting step by a nut. Thus, the driving plate 290 is fixedly mounted on the stirring shaft 240, so that the rotation of the stirring shaft 240 can drive the driving plate 290 to rotate, and then the driving rod 231 is driven to slide along the sliding groove 303 through the driving rod, so that the coolant storage ring 230 is rotatably mounted in the cooling cover 120.

As shown in combination with Figures 2 and 5, in this embodiment, the heat conductive ring 210 is evenly provided with grooves 311 for allowing bubbles in the syrup to move upward, and the stirring rod 501 is provided with a scraper 502 that extends between adjacent heat conductive rings 210 and fits against the inner wall of the tank body 100.

In actual use, since bubbles are generated during the boiling of the syrup raw materials, in order to prevent the heat-conducting ring 210 from blocking the rising of the bubbles, resulting in the presence of bubbles in the syrup that affect its quality, the notch 311 and the scraper 502 are arranged so that when the stirring shaft 240 drives the stirring rod 501 for stirring, the scraper 502 can be driven to rotate between adjacent heat-conducting rings 210, thereby driving the bubbles to move, so that the bubbles can move upward and be discharged from the notch 311. At the same time, the scraper 502 scrapes against the inner wall of the tank body 100, which can better prevent the syrup from adhering to the tank wall and causing it to burn during boiling.

As shown in FIGS. 5-7 , in this embodiment, the agitator assembly includes an agitator plate 250 sleeved on the corresponding agitator rod 501, and both ends of the agitator plate 250 are arranged on the agitator shaft 240 through a tension spring 260, and the tension spring 260 is used to drive the agitator plate 250 to move toward the agitator shaft 240, and a guide rod 511 is arranged at the upper end of the agitator plate 250;

The control component includes a pressure plate 270 that can be raised and lowered on the stirring shaft 240. A convex plate 610 is coaxially provided on the lower plate surface of the pressure plate 270. A groove 611 corresponding to the guide rod 511 on the convex plate 610 is provided for the corresponding guide rod 511 to extend into. The two side walls of the groove 611 form a guiding inclined surface 612. The rotation of the agitator plate 250 is used to drive the guide rod 511 to slide out of or into the groove 611 along the guiding inclined surface 612, so as to realize the reciprocating movement of the agitator plate 250 along the stirring rod 501.

In actual use of this embodiment, a boss ring for limiting the agitator plate 250 is disposed on the outer cover of the agitator rod 501, so that the distance that the agitator plate 250 moves along the agitator rod 501 toward the agitator shaft 240 under the action of the tension spring 260 is limited, that is, the agitator plate 250 is slidably mounted on the agitator rod 501;

Among them, by setting the pressure plate 270, the convex plate 610, the groove 611 and the guide inclined surface 612, when the pressure plate 270 is lowered, the guide rod 511 is extended into the corresponding groove 611. At this time, the stirring rod 501 rotates to drive the agitator 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 surface 612, and then the stirring rod 501 drives the agitator plate 250 to rotate while the agitator plate 250 reciprocates along the agitator plate 501, which can better drive the syrup in the tank body 100 to generate turbulence, so that the syrup can more evenly contact the heat conductive ring 210 for heat exchange and cooling, thereby improving the cooling effect of the cooling component; when the pressure plate 270 moves upward, the guide rod 511 can be separated from the corresponding groove 611. At this time, the agitator plate 250 will not reciprocate on the agitator plate 501 as the agitator rod 501 rotates, that is, the agitator component does not work.

Among them, in order to better realize the downward movement of the pressure plate 270 so that 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, and a guide surface 621 for guiding the guide rod 511 into the groove 611 is provided on the outer wall of the guide ring 620. By utilizing the setting of the guide ring 620 and the guide surface 621, when the pressure plate 270 moves downward, the setting of the guide surface 621 can enable the guide rod 511 to fit the convex plate 610 and slide into the corresponding groove 611, so that the flow stirring component can work.

In this embodiment, the control part also includes a mounting cylinder 280 provided on the tank cover 110 and sleeved on the outside of the stirring shaft 240, and a slider 711 is 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 fixed cylinder 630 sleeved on the outside of the stirring shaft 240 and extending through the mounting cylinder 280, and a sliding groove 631 for the corresponding slider 711 to slide is provided on the outer side wall of the fixed cylinder 630; the outer sleeve of the fixed cylinder 630 located in the tank body 100 is provided with a slider 711 for driving the pressure plate 270 downward. The spring 271 is moved, and an installation groove 632 is relatively provided on the outer side wall of the fixed cylinder 630. A locking groove 633 is provided on the bottom wall of the installation groove 632. The locking groove 633 includes an upper positioning portion and a lower positioning portion. A rotatable locking rod 640 is provided in the installation cylinder 280. A sliding rod 721 sliding in the locking groove 633 is provided at one end of the locking rod 640. The sliding rod 721 slides to the upper positioning portion and the lower positioning portion to lift the pressure plate 270, thereby realizing the state switching of the agitation component.

In this embodiment, the lower end of the mounting tube 280 extends outward to form a mounting portion 712, and the mounting portion 712 is fixedly mounted on the tank cover 110 by screws;

The slide groove 631 and the slider 711 are matched to form a keyway between the fixing tube 630 and the mounting tube 280, so that the pressure plate 270 can be lifted and installed on the tank cover 110 and cannot rotate in the circumferential direction.

As shown in FIG8 , the locking groove 633 is a polygonal groove, which includes an upper recess 801 and a lower recess 802. The upper recess 801 and the lower recess 802 respectively form a first bending groove 803 and a second bending groove 804 on both sides. The first bending groove 803 is provided with a first inclined surface 805 opposite to the upper recess 801 and a second inclined surface 806 opposite to the lower recess 802. The second bending groove 804 is provided with a third inclined surface 807 opposite to the lower recess 802. In actual use, one end of the locking rod 640 forms a sliding rod 721 sliding in the locking groove 633, and the other end forms a mounting rod 722 rotatably mounted on the mounting cylinder 280. The spring 271 always pushes the pressure plate 270 downward, driving the fixing cylinder 630 downward, wherein the upper recess 801 forms an upper positioning portion, and the lower recess 802 forms a lower positioning portion. When the sliding rod 72 When the guide rod 511 is in the upper concave portion 801, at this time, the pressure plate 270 is in a downward movement state, that is, its downward movement can make the guide rod 511 extend into the groove 611 to realize the operation of the agitator assembly. At this time, the fixed cylinder 630 is lifted up, so that the slide bar 721 slides into the first bending groove 803 under the guidance of the first inclined surface 805, and the slide bar 721 slides into the lower concave portion 802 under the guidance of the second inclined surface 806. At this time, the fixed cylinder 630 is released, so that under the action of the spring 271, the pressure plate 270 is in an upward movement state, even if the guide rod 511 is separated from the groove 611, at this time, by lifting and loosening the fixed cylinder 630 again, the slide bar 721 can slide along the second bending groove 804 to the upper concave portion 801 under the action of the third inclined surface 807, so that the slide bar 721 slides in the locking slide groove 633 to switch whether the agitator assembly is working;

In order to facilitate the operator to lift the fixing tube 630 , a pressing ring 634 is provided at the upper end of the fixing tube 630 .
