Description

Technical Field

[0001] The invention relates to a heating system, in particular to a coffee bean roasting heating system. Background Art

[0002] At present, the conventional coffee bean roasting heating system can refer to the heating system disclosed in a patent for a coffee bean roasting device (Announcement No. CN118203127A), that is, a heater, which is a device for heating the coffee beans inside the heating stirring barrel after the coffee beans are fed into the heating stirring barrel through a feed channel. However, the existing heating system generally still adopts a gas-fired air heating method, which not only has a low heating efficiency, but also is complicated and inconvenient to maintain and replace later. Summary of the invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a coffee bean roasting and heating system, which can heat the air to be entered into the heating and stirring barrel more evenly and quickly to improve the heating efficiency.

[0004] The present invention provides the following technical solutions:

[0005] A coffee bean roasting and heating system comprises a heating box with an air intake fan installed at the bottom, the top of the heating box is open, and the periphery of the opening is sealed and installed at the bottom of a group of air intake channels, a stirring barrel is fixed in the air intake channel and suspended above the opening of the heating box, a hot air inlet for the heated air flow to enter is provided on one side of the stirring barrel, and an exhaust gas outlet is provided on the other side for the air flow to flow out, so that the hot air flow heated by the heating box can directly enter the suspended gap between the stirring barrel and the heating box through the opening to the maximum extent, and the suspended gap not only provides a channel for the hot air flow to flow, but also provides a heat-insulating environment effect for the stirring barrel, the hot air flow flowing out of the heating box passes through the suspended gap between the stirring barrel and the heating box and then enters the stirring box through the hot air inlet to heat the coffee beans, and the heated exhaust gas flows out through the exhaust gas outlet to realize the circulation of the air flow;

[0006] A heating component is arranged in the heating box, and the heating component is installed in the heating box in a side-pull-out manner. Therefore, when the heating component in the heating box needs to be disassembled, it is only necessary to directly pull the heating component out of the heating box, which is relatively time-saving and labor-saving. A group of partitions are also arranged at the bottom of the heating box, and the partitions are used to separate the air inlet of the air intake fan and the heating component in two chambers, and the partitions are also provided with multiple rows of through holes for connecting the two chambers. The bottom of the chamber where the heating component is located is also provided with multiple groups of bending plates, and the bending plates are downwardly flared and are one-to-one correspondingly arranged above each row of through holes;

[0007] Therefore, after the airflow driven by the intake fan enters the lower chamber, it enters the upper chamber through each row of through holes. When the airflow enters the upper chamber, since the bending mouth of the bending plate is an expanded cover arranged above the through hole, the airflow can diffuse to both sides of the bending plate under the obstruction and buffering of the bending plate, and then the diffused airflow can diffuse toward the middle along the upper plate surface of the bending plate, so as to achieve the purpose of uniform and slow diffusion of the airflow into the upper chamber. The airflow that slowly and uniformly enters the upper chamber can be fully heated by the heating component to improve the heating efficiency.

[0008] Preferably, the heating components are provided with at least two groups, and are arranged in layers from bottom to top to improve heating efficiency.

[0009] Preferably, the heating assembly includes a group of rectangular frames for installing the heating element body, and four groups of guide wheels distributed in a rectangular shape are fixed on both sides of the rectangular frames. A guide groove corresponding to each group of rectangular frames for pull-out guiding installation is opened in the heating box, and the four groups of guide wheels on each side of each group of rectangular frames are guided and limited in two groups of parallel guide grooves, so as to achieve stable and convenient pulling and pulling operation, and the cost is also low.

[0010] Preferably, two sets of fixed edges extend outward from the left and right sides of the rectangular frame, and after the rectangular frame drives the heating element body to slide into the heating box, the fixed edges rest against the side walls of the heating box and are locked and fixed by screws to ensure structural stability during heating.

[0011] Preferably, the heating element body is a U-shaped electric heating tube, whose front end pipeline joint passes through the front connecting pipeline of the rectangular frame, and whose rear end U-shaped bottom passes through the rear side of the rectangular frame, so as to realize the support of the rear side plate of the rectangular frame for the electric heating tube and improve the heating stability.

[0012] Preferably, the rear side panels of the rectangular frame are provided with through grooves corresponding to the heating element bodies, and the extension direction of the through grooves intersects with the opening at an angle of 45°. The heating element body is inclined at an angle of 45° and passes through the through grooves. In this way, it can be ensured that the airflow rising from the bottom can fully exchange heat with the electric heating tube.

[0013] Preferably, spiral heat dissipation fins are also provided outside the electric heating tube.

[0014] The beneficial effects of the present invention are:

[0015] In the present invention, the hot air flow heated by the heating box can directly enter the suspended gap between the stirring barrel and the heating box through the opening to the maximum extent. The suspended gap not only provides a circulation channel for the hot air flow, but also provides a heat preservation environment effect for the stirring barrel. The hot air flow flowing out of the heating box passes through the suspended gap between the stirring barrel and the heating box and enters the stirring box through the hot air inlet to heat the coffee beans. The heated exhaust gas flows out from the exhaust gas outlet to realize the circulation of the air flow.

[0016] 2. When you need to disassemble the heating component in the heating box, you only need to directly pull the heating component out of the heating box, which saves time and effort;

[0017] 3 After the airflow driven by the air intake fan enters the lower chamber, it enters the upper chamber through each row of through holes. When the airflow enters the upper chamber, since the bending opening of the bending plate is an expanded cover arranged above the through hole, the airflow can diffuse to both sides of the bending plate under the obstruction and buffering of the bending plate, and then the diffused airflow can diffuse toward the middle along the upper plate surface of the bending plate, so as to achieve the purpose of uniform and slow diffusion of the airflow into the upper chamber. The airflow that slowly and uniformly enters the upper chamber can be fully heated by the heating component to improve the heating efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example 1

[0028] like Figure 1-6 As shown, a coffee bean roasting and heating system, in this embodiment, includes a heating box 2 with an air intake fan 1 installed at the bottom, the top of the heating box 2 is open, and the periphery of the open is sealed and installed at the bottom of a group of air intake channels 3, the stirring barrel 4 is fixed in the air intake channel 3, and is suspended above the opening of the heating box 2, and one side of the stirring barrel is also provided with a hot air inlet 5 for the heating air flow to enter, and the other side is provided with an exhaust gas outlet 6 for the air flow to flow out. At this point, after the coffee beans enter from the feeding port at the top of the stirring barrel 4, the stirring shaft therein rotates to stir the materials, and the bottom The discharge pipe connected on one side can be used for discharging, which is a prior art and will not be described in detail here. During stirring, the hot air flow heated by the heating box 2 can directly enter the suspended gap between the stirring barrel 4 and the heating box 2 through the opening to the maximum extent. The suspended gap not only provides a circulation channel for the hot air flow, but also provides a heat-insulating environment effect for the stirring barrel 4. The hot air flow out of the heating box 2 passes through the suspended gap between the stirring barrel 4 and the heating box 2 and then enters the stirring box through the hot air inlet 5 to heat the coffee beans. The heated exhaust gas flows out from the exhaust gas outlet 6 to realize the circulation of the air flow.

[0029] A heating assembly 7 is arranged in the heating box 2, and the heating assembly 7 is installed in the heating box 2 in a side-pull-out manner. Therefore, when the heating assembly 7 in the heating box 2 needs to be disassembled, it is only necessary to directly pull the heating assembly 7 out of the heating box 2, which is relatively time-saving and labor-saving. A group of partitions 8 are also arranged at the bottom of the heating box 2. The partitions 8 are used to separate the air inlet of the air intake fan 1 and the heating assembly 7 in two chambers, and the partitions 8 are also provided with multiple rows of through holes 9 for connecting the two chambers. The bottom of the chamber where the heating assembly 7 is located is also provided with multiple groups of bending plates 10, and the bending plates 10 are downwardly expanded and one-to-one correspondingly arranged above each row of through holes 9;

[0030] Therefore, after the airflow driven by the intake fan 1 enters the lower chamber, it enters the upper chamber through each row of through holes 9. When the airflow enters the upper chamber, since the bending mouth of the bending plate 10 is an expansion-shaped cover arranged above the through hole 9, the airflow can diffuse to both sides of the bending plate 10 under the obstruction and buffering of the bending plate 10, and then the diffused airflow can diffuse toward the middle along the upper plate surface of the bending plate 10, so as to achieve the purpose of uniform and slow diffusion of the airflow into the upper chamber. The airflow that slowly and uniformly enters the upper chamber can be fully heated by the heating component 7 to improve the heating efficiency.

[0031] Example 2

[0032] A coffee bean roasting heating system, in this embodiment, is further defined based on embodiment 1, wherein three groups of heating components 7 are provided, and are arranged in layers from bottom to top to improve heating efficiency. Each group of heating components 7 includes a group of rectangular frames 71 for mounting a heating element body 75, and four groups of guide wheels 72 distributed in a rectangular shape are fixed on both sides of the rectangular frames 71, and a guide groove 73 corresponding to each group of rectangular frames 71 is provided in the heating box 2 for pull-out guiding installation, and the four groups of guide wheels 72 on each side of each group of rectangular frames 71 are guided and limited in two groups of parallel guide grooves 73, so as to achieve stable and convenient pull-out operation, and the cost is also low. Two groups of fixed edges 74 are also extended outward from the left and right sides of the rectangular frame 71, and after the rectangular frame 71 drives the heating element body 75 to slide into the heating box 2, the fixed edges 74 are against the side walls of the heating box 2, and are fixed and fixed by screws to ensure structural stability during heating. The heating element body 75 is a U-shaped electric heating tube, and its front end pipeline joint 76 passes through the front side connecting pipeline of the rectangular frame 71, and its rear end U-shaped bottom passes through the rear side of the rectangular frame 71, so as to realize the support of the electric heating tube by the rear side plate of the rectangular frame 71, thereby improving the heating stability. A through groove 77 corresponding to the heating element body 75 is provided on the rear side plate of the rectangular frame 71, and the extension direction of the through groove 77 intersects with the opening at a 45° angle. The heating element body 75 is arranged to pass through the through groove 77 at an angle of 45°, so as to ensure that the airflow rising from the bottom can fully exchange heat with the electric heating tube. A spiral heat dissipation fin 78 is also provided outside the electric heating tube.

[0033] The working principle of the present invention is as follows: in the present invention, the hot air flow heated by the heating box 2 can directly enter the suspended gap between the stirring barrel 4 and the heating box 2 through the opening to the maximum extent. The suspended gap not only provides a circulation channel for the hot air flow, but also provides a heat-insulating environment effect for the stirring barrel 4. The hot air flow flowing out of the heating box 2 passes through the suspended gap between the stirring barrel 4 and the heating box 2 and then enters the stirring box through the hot air inlet 5 to heat the coffee beans. The heated exhaust gas flows out from the exhaust gas outlet 6 to realize the circulation of the air flow. When it is necessary to disassemble the heating component 7 in the heating box 2, it is only necessary to directly remove the heating component 7 from the heating box 2. After the airflow enters the lower chamber, it enters the upper chamber through each row of through holes 9. When the airflow enters the upper chamber, the bending mouth of the bending plate 10 is an expansion-shaped cover arranged above the through hole 9. Therefore, the airflow can diffuse to both sides of the bending plate 10 under the obstruction and buffering of the bending plate 10, and then the diffused airflow can diffuse toward the middle along the upper plate surface of the bending plate 10, so as to achieve the purpose of uniform and slow diffusion of the airflow into the upper chamber. The airflow that slowly and uniformly enters the upper chamber can be fully heated by the heating component 7 to improve the heating efficiency.
