It has special functions that are beneficial to human health, such as regulating blood sugar. It is generally made by extracting fructose from starch and then undergoing multi-stage deep processing.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0032] Depend on Figure 1 and Figure 2 As shown, it is a schematic diagram of the structure of the heating mechanism for evaporating allulose in this embodiment, including an evaporator body 1, a steam input pipe 2, a material input pipe 3 and a material output pipe 4. A steam input pipe 2 for conveying steam with heat is installed on one side of the surface of the evaporator body 1, and a material input pipe 3 for conveying material to be heated is installed on the side of the evaporator body 1 opposite to the steam input pipe 2. A material output pipe 4 is installed at the bottom of the evaporator body 1. An evaporation mechanism 5 is installed inside the evaporator body 1. The evaporation mechanism 5 includes a matching pipe 51, a connecting pipe 52 and a curved heating pipe 53. The matching pipe 51 is installed inside the evaporator body 1, and the matching pipe 51 is connected to the steam input pipe 2. A curved heating pipe 53 for expanding the contact area with the material for heating is installed at the end of the matching pipe 51, and the connecting pipe 52 is installed at the end of the curved heating pipe 53.

[0033] During use, the material to be evaporated and heated is input into the evaporator body 1 through the material input pipe 3, and then the heating steam is input into the matching pipe 51 through the use of the steam input pipe 2. The matching pipe 51, the connecting pipe 52 and the curved heating pipe 53 are used to increase the contact surface between the outer wall of the pipe and the material, so that the material can more stably receive the heat conducted by the steam, complete better heating treatment, and the moisture inside the material is converted into water vapor due to the high temperature, and is directly discharged through the upper end part of the evaporator body 1, thereby realizing the evaporation process of allulose, thereby ensuring the working quality of the equipment itself.

[0034] By the attached Figure 3 and Figure 4 As shown, it is a schematic diagram of the structure of the evaporation mechanism 5 in this embodiment. The evaporation mechanism 5 also includes a spiral heating tube 54 and a delivery tube 55. The spiral heating tube 54 is installed inside the evaporator body 1, and the end of the spiral heating tube 54 is connected to the end of the connecting tube 52. The spiral heating tube 54 is used to heat the shell temperature of the evaporator body 1 using the waste heat of steam. The delivery tube 55 is installed at the end of the spiral heating tube 54, and a control valve is installed on the outside of the delivery tube 55.

[0035] During use, the spiral heating tube 54 is used to transport the steam that has heated the material. At this time, the steam is gradually transported along the inner wall of the evaporator body 1 with the cooperation of the spiral heating tube 54, and the evaporator body 1 itself is heated to increase the overall temperature of the evaporator body 1, thereby preventing the evaporator body 1 from having a too low temperature, which would cause the internal heat of the evaporator body 1 to lose too much heat quickly, thereby realizing multiple utilization of the steam heat, and then the steam is directly discharged through the transport tube 55, so that other components can reheat the steam and circulate it for use, thereby ensuring the working quality of the equipment itself.

[0036] By the attached Figure 5 As shown, the curved heating tube 53 is formed by connecting a plurality of groups of curved pipes, the inlet and outlet ends of the curved heating tube 53 are both installed with connecting flanges, and a support frame for assisting the curved heating tube 53 in positioning is installed on the inner wall of the evaporator body 1 on the side of the curved heating tube 53.

[0037] During use, the design of the structure of the curved heating tube 53 itself can extend the path of steam transportation inside the pipeline, extend the time for steam to heat the material, and the contact area between the curved heating tube 53 itself and the material is enlarged, so that the steam can better heat the material. The installation of the connecting flanges at both ends of the curved heating tube 53 facilitates the docking and connection between the curved heating tube 53 and the matching tube 51 and the connecting tube 52, thereby ensuring the overall sealing of the pipeline and preventing steam leakage. Finally, with the cooperation of the support frame, the position of the curved heating tube 53 itself is reinforced and supported to ensure the stability of the curved heating tube 53 when in use.

[0038] By the attached Figure 4 As shown, the spiral heating tube 54 is attached to the inner wall of the evaporator body 1 in a spiral upward trend to heat the shell of the evaporator body 1, and a connecting notch is opened at the middle end of the spiral heating tube 54 to communicate with other components.

[0039] During use, the waste heat of the steam is recycled through the design of the shape and structure of the spiral heating tube 54, so that the steam can heat the entire evaporator body 1 along the tube wall of the spiral heating tube 54, and the design of the connecting notch facilitates the connection between the spiral heating tube 54 and other components, so that the steam can be reasonably and fully utilized, and the heat can be recycled multiple times, thereby ensuring the use effect of the equipment itself.

[0040] By the attached Figure 6 As shown, it is a schematic diagram of the structure of the stirring component 56 in this embodiment. The evaporation mechanism 5 also includes a stirring component 56 that uses flowing steam as a power for stirring. The stirring component 56 includes a transmission rod 561, a matching impeller 562, a stirring block 563 and a stirring rod 564. The transmission rod 561 is rotatably installed inside the matching pipe 51 and the connecting pipe 52, and the matching impeller 562 is fixedly installed at the end of the transmission rod 561. The stirring block 563 is fixedly installed on the side of the end of the transmission rod 561 opposite to the matching impeller 562, and the stirring rod 564 is fixedly installed on the outside of the stirring block 563 at an equal distance.

[0041] When the steam flows along the matching pipe 51 during use, the steam will push the matching impeller 562. Due to the matching angle and structure of the matching impeller 562, the matching impeller 562 will drive the transmission rod 561 to rotate, thereby driving the stirring block 563 on the side to rotate synchronously, so that the stirring rod 564 stirs the material inside the evaporator body 1, allowing the material to better contact with the surface of the matching pipe 51 and the connecting pipe 52, thereby achieving more stable heat conduction. There is no need to install motors and other driving components as the whole, and it basically relies on the flow of steam as power to achieve reasonable use of steam.

[0042] By the attached Figure 7 As shown, it is a structural schematic diagram of the preheating mechanism 6 in this embodiment. The heating mechanism also includes a preheating mechanism 6 that uses steam waste heat to preheat the material. The preheating mechanism 6 includes a heating component 61, a first connecting pipe 62 and a second connecting pipe 63. The first connecting pipe 62 and the second connecting pipe 63 are both installed on the connecting notch in the spiral heating pipe 54. The first connecting pipe 62 and the second connecting pipe 63 are both connected to the spiral heating pipe 54. The heating component 61 is installed outside the material input pipe 3. The air inlet end of the heating component 61 is connected to the first connecting pipe 62, and the air outlet end of the heating component 61 is connected to the second connecting pipe 63.

[0043] During use, the first connecting tube 62 and the second connecting tube 63 are installed on the corresponding connecting notches on the side of the spiral heating tube 54 to ensure that the steam transported inside the spiral heating tube 54 will enter the heating component 61 through the first connecting tube 62, and then the steam in the heating component 61 will re-enter the spiral heating tube 54 along the second connecting tube 63, and then be discharged through the spiral heating tube 54, thereby realizing the recycling of heat in the steam. The heating component 61 will heat the outer wall of the material input pipe 3 and pre-heat the material in the material input pipe 3 to ensure the stability of the equipment during operation.

[0044] By the attached Fig. 9 As shown, it is a structural schematic diagram of the heating component 61 in this embodiment, the heating component 61 also includes a heating shell 611, an insulating layer 612 and a heating pipeline 613, the heating shell 611 is installed on the outside of the material input pipe 3, an insulating cavity is opened inside the heating shell 611, the insulating cavity is filled with an insulating layer 612 for reducing heat loss, a heating pipeline 613 for preheating the material inside the material input pipe 3 is arranged outside the material input pipe 3, and the air inlet end of the heating pipeline 613 is connected to the heating component 61, and the air outlet end of the heating pipeline 613 is connected to the second connecting pipe 63.

[0045] During use, the first connecting pipe 62 is used, and steam enters the interior of the heating shell 611. At this time, the heating shell 611 cooperates with the steam transported inside to regulate the overall temperature of the heating shell 611, thereby increasing the temperature of the material input pipe 3 itself, and realizing preheating treatment of the material in the material input pipe 3. The filling of the thermal insulation layer 612 can effectively prevent excessive heat loss inside the heating shell 611, thereby facilitating subsequent steam heating treatment of the temperature of the shell of the evaporator main body 1.

[0046] By the attached Fig.10 As shown, it is a structural schematic diagram of the exhaust mechanism 7 in this embodiment. The heating mechanism also includes an exhaust mechanism 7 for conveying heated steam. The exhaust mechanism 7 includes a guide tank 71, a water vapor conveying pipe 72 and a water vapor exhaust pipe 73. The guide tank 71 is fixedly installed on the upper surface of the evaporator body 1, the interior of the guide tank 71 is connected to the evaporator body 1, the water vapor conveying pipe 72 is fixedly installed on the side of the guide tank 71, and the water vapor exhaust pipe 73 is installed at the end of the water vapor conveying pipe 72.

[0047] During use, the heated water vapor is collected through the use of the guide tank 71 and the water vapor delivery pipe 72, and then the water vapor is transported to subsequent components with the cooperation of the water vapor exhaust pipe 73. Through the processing of subsequent components such as the condenser, resource recovery and utilization are achieved.

[0048] By the attached Fig.10As shown, connecting flanges are installed at both ends of the water vapor exhaust pipe 73, and the water vapor exhaust pipe 73 is connected to the water vapor delivery pipe 72 by means of the connecting flanges and fixing bolts. During use, the water vapor exhaust pipe 73 is assisted to quickly connect with the water vapor delivery pipe 72 through the cooperation of the connecting flanges and the fixing bolts, thereby ensuring the sealing of the connection between the water vapor delivery pipe 72 and the water vapor exhaust pipe 73, and facilitating the discharge of water vapor.

[0049] By the attached Figures 1 to 10 As shown, a heating method for evaporating allulose comprises the following steps: S1, input, input the material to be processed into the evaporator body 1 through the material input pipe 3, during the material transportation process of the material input pipe 3, steam is input into the heating component 61 through the cooperation of the first connecting pipe 62 and the second connecting pipe 63, and the area of ​​the material input pipe 3 wrapped by the heating component 61 is heated to realize preheating of the material; S2, heating and evaporation. The steam required for heating is input into the evaporator body 1 through the use of the steam input pipe 2. Then, through the coordination of the matching pipe 51, the connecting pipe 52, and the curved heating pipe 53, the steam is stably transported along the inner walls of the matching pipe 51, the connecting pipe 52, and the curved heating pipe 53, thereby extending the time the steam exists in the evaporator body 1 and the length of the circulation path. In addition, the structure of the curved heating pipe 53 is used to expand the contact area between the steam and the material, making the heating of the material more stable. Due to the increase in temperature, the excess water in the material is converted into steam under high temperature processing and discharged through the upper end component of the evaporator body 1. S3, heat recovery and utilization, after the steam heats the material, the steam continues to flow along the spiral heating tube 54, and the residual heat in the steam is used to heat the shell of the evaporator body 1, thereby increasing the temperature of the shell of the evaporator body 1 and reducing heat loss. When the steam is transported inside the spiral heating tube 54, the steam will first enter the preheating mechanism 6, and after preheating the material in the material input pipe 3 in accordance with the above steps, it will continue to be transported along the spiral heating tube 54, and finally discharged through the transport pipe 55; S4, discharge of steam. Due to the difference in boiling point of water itself, water will be converted into water vapor due to high temperature. Under the condition of different density, water vapor is directly input into water vapor discharge pipe 73 through diversion tank 71 and water vapor delivery pipe 72, so that water vapor can be collected by water vapor discharge pipe 73 and then recovered and utilized through condenser. S5. The discharge and collection of sugars. Through the design of the conical shell structure at the bottom of the evaporator body 1, the material with water discharged will automatically flow to the bottom of the evaporator body 1 and concentrate. Then, with the cooperation of the material output pipe 4, the material heated inside the evaporator body 1 is discharged to complete the collection of sugars.
