Description

Technical Field

[0001] This utility model relates to the field of chocolate production technology, and in particular to a cocoa processing and refining machine. Background Technology

[0002] Chocolate is a sweet food made primarily from cocoa liquor and cocoa butter produced during the processing of cocoa beans. During the processing of cocoa, the cocoa liquor needs to be refined. Through stirring, heating, emulsification, and other methods, the aromatic properties of the finished chocolate are improved and negative "acidity" and residual moisture are eliminated.

[0003] Existing technology, such as a simple vertical chocolate refining machine disclosed in CN217389885U, includes: a mixing chamber, with three legs fixedly installed at the bottom of the mixing chamber, the three legs being equidistantly distributed in a ring about the vertical center line of the mixing chamber... This allows for more thorough mixing of the raw materials, improving refining efficiency. The stirring shaft drives the scraper to rotate, effectively scraping off the raw materials on the surface of the heating plate, preventing the raw materials at the bottom from burning due to prolonged heating.

[0004] When stirring and heating cocoa liquor, the cocoa liquor can only be mixed with the air above by stirring, which is not efficient enough. In addition, heating devices such as heating plates heat the cocoa liquor at the bottom and other external parts, which is not heated enough. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to mix cocoa liquor with the air above through stirring, resulting in insufficient emulsification efficiency, and the insufficient heating of the cocoa liquor at the bottom and other external locations through heating devices such as heating plates. Therefore, this invention proposes a cocoa processing and refining machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a cocoa refining machine, including a casing, a mixing tank, a sealing cover, and a stirring shaft rotatably installed inside the mixing tank. An air intake mechanism and a heating mechanism are installed on the inner wall of the casing, and a gas release mechanism is installed at the bottom of the mixing tank.

[0008] The air outlet of the air inlet mechanism is connected to the heating mechanism, and the air outlet of the heating mechanism is connected to the gas release mechanism.

[0009] The gas release mechanism includes a hollow turntable with an internal cavity, an exhaust port, a one-way exhaust structure, and a flow structure. The hollow turntable is fixedly connected to the outer wall of the stirring shaft, and the hollow turntable is rotatably installed at the bottom of the stirring tank. Several lower ends of the top of the hollow turntable are connected to the exhaust port of the cavity, and the exhaust port is provided with a one-way exhaust structure. The cavity is connected to the flow structure.

[0010] The top of the hollow turntable is fixed with several stirring rods, and the lower end of the stirring rods extends into the cavity. The lower end of the stirring rod is provided with a vertical hole, and the outer wall of the stirring rod is provided with an auxiliary exhaust hole that communicates with the vertical hole. The interior of the auxiliary exhaust hole is provided with a one-way exhaust structure.

[0011] Furthermore: the heating mechanism includes a heat insulation box and heating rods. The heat insulation box is fixedly installed on the inner wall of the housing. Several heating rods are fixedly installed inside the heat insulation box. The heating rods are arranged in parallel and laterally. The air outlet of the heat insulation box is connected to the air intake mechanism and the gas release mechanism through a hose and a connecting structure.

[0012] Furthermore: the air intake mechanism includes an air pump, which is fixedly installed on the inner wall of the housing, and the air outlet of the air pump is connected to the heating mechanism via a hose.

[0013] Furthermore: the flow structure includes a nozzle, a conveying hole, and a connecting hole. The upper end of the stirring shaft is provided with a conveying hole, and the lower end of the stirring shaft is provided with a connecting hole, which connects the cavity and the conveying hole. The bottom of the sealing cover is fixedly installed with a nozzle, and the upper end of the nozzle is connected to the air inlet of the heating mechanism through a hose.

An inverted L-shaped hole is formed inside the piston rod, and the upper and lower ends of the inverted L-shaped hole are respectively formed on the upper outer wall and the lower end face of the piston rod.

[0015] The cocoa processing and refining machine proposed in this utility model has the following advantages: while stirring and refining the cocoa mass, it can pump air or oxygen heated by the heating mechanism into the gas release mechanism through the air intake mechanism, and release it in the form of bubbles at the bottom of the mixing tank. The air or oxygen is mixed more evenly and fully with the cocoa mass, and the emulsification effect is better. The cocoa mass is heated by air or oxygen containing heat, and the air or oxygen is evenly and comprehensively distributed inside the cocoa mass.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 As an embodiment of this utility model, a cocoa processing and refining machine is disclosed, including a housing 1, a mixing tank 2, a sealing cover 3, and a stirring shaft 4 rotatably installed inside the mixing tank 2. An air intake mechanism 5 and a heating mechanism 6 are installed on the inner wall of the housing 1. A gas release mechanism 7 is installed at the bottom of the mixing tank 2. A motor is fixedly installed at the bottom of the stirring shaft 4, and the output shaft of the motor is connected to the stirring shaft 4. After the cocoa liquor is injected into the mixing tank 2 and the sealing cover 3 is closed, the motor drives the stirring shaft 4 and the stirring rod 8 on it and other stirring structures to rotate, thereby stirring and refining the cocoa liquor.

[0024] The air outlet of the air inlet mechanism 5 is connected to the heating mechanism 6, and the air outlet of the heating mechanism 6 is connected to the gas release mechanism 7.

[0025] The gas release mechanism 7 includes a hollow turntable 71 with an internal cavity 72, an exhaust port 73, a one-way exhaust structure 74, and a flow structure 75. The hollow turntable 71 is fixedly connected to the outer wall of the stirring shaft 4, and the hollow turntable 71 is rotatably installed at the bottom of the stirring tank 2. Several lower ends of the top of the hollow turntable 71 are connected to the exhaust port 73 of the cavity 72, and the exhaust port 73 is provided with a one-way exhaust structure 74. The cavity 72 is connected to the flow structure 75.

[0026] A number of stirring rods 8 are fixedly provided on the top of the hollow turntable 71, and the lower end of the stirring rods 8 extends into the cavity 72. A vertical hole 9 is provided at the lower end of the stirring rods 8, and an auxiliary exhaust hole 10 communicating with the vertical hole 9 is provided on the outer wall of the stirring rods 8. A one-way exhaust structure 74 is provided inside the auxiliary exhaust hole 10.

[0027] In this embodiment, the air intake mechanism 5 pumps filtered air or oxygen into the heating mechanism 6, which heats the air or oxygen. The heated air or oxygen enters the gas release mechanism 7 and is released at the bottom of the mixing tank 2 in the form of bubbles. It mixes with the stirred cocoa liquor, emulsifies the cocoa liquor with air or oxygen, and transfers the heat contained in the air or oxygen to the cocoa liquor, heating it. At the same time, the density of the air or oxygen decreases and rises with the stirring due to buoyancy, thereby allowing the cocoa liquor to exchange between the top and bottom.

[0028] Heated air or oxygen enters through the air or oxygen inlet cavity 72 and is discharged through the exhaust port 73. The hollow turntable 71, driven by the stirring shaft 4, rotates while the exhaust port 73 is venting, so that the air or oxygen is released and mixed more comprehensively and evenly.

[0029] Not only can the hollow turntable 71 drive several stirring rods 8 and their blades and other stirring structures to stir the cocoa liquor, but the air or oxygen in the cavity 72 can also be discharged through the vertical hole 9 and the auxiliary exhaust hole 10, further releasing the air or oxygen into the cocoa liquor at the middle height, increasing the uniformity and fullness of the mixing of air or oxygen with the cocoa liquor.

[0030] The heating mechanism 6 includes a heat insulation box 61 and heating rods 62. The heat insulation box 61 is fixedly installed on the inner wall of the housing 1. Several heating rods 62 are fixedly installed inside the heat insulation box 61. The heating rods 62 are arranged in parallel and laterally. The air outlet of the heat insulation box 61 is connected to the air intake mechanism 5 and the gas release mechanism 7 through a hose and a connecting structure.

[0031] In this embodiment, air or oxygen enters the insulation box 61 from the bottom and exits from the top, and flows through a plurality of heating rods 62 in sequence to heat the air.

[0032] The air intake mechanism 5 includes an air pump 51, which is fixedly installed on the inner wall of the housing 1. The air outlet of the air pump 51 is connected to the heating mechanism 6 through a hose.

[0033] In this embodiment, an air filter is installed at the air inlet of the air pump 51, or the air inlet of the air pump 51 is directly connected to a gas tank containing oxygen, thereby starting the air pump 51 to pump the air filtered by the filter or the oxygen in the gas tank into the heat insulation box 61, which reduces internal heat loss, for heating, and then pumping it into the cavity 72.

[0034] The flow structure 75 includes a nozzle 751, a conveying hole 752, and a connecting hole 753. The upper end of the stirring shaft 4 is provided with a conveying hole 752, and the lower end of the stirring shaft 4 is provided with a connecting hole 753. The connecting hole 753 connects the cavity 72 and the conveying hole 752. The bottom of the sealing cover 3 is fixedly installed with a nozzle 751, and the upper end of the nozzle 751 is connected to the air inlet of the heating mechanism 6 through a hose. The lower end of the nozzle 751 is inserted into the conveying hole 752.

[0035] In this embodiment, the tip of the lower end of the nozzle 751 of the upper sealing cover 3 is inserted into the connecting hole 753 and the conical surface of the tip abuts against the sealing ring at the upper end of the stirring shaft 4 to form a sealed connection. Air or oxygen heated by the heating rod 62 enters the nozzle 751 through the hose, then enters the conveying hole 752 through the lower end of the nozzle 751, and then enters the cavity 72 through the connecting hole 753.

[0036] The one-way exhaust structure 74 includes a piston rod 741, an inverted L-shaped hole 742, a spring 743, and a convex ring 744. The piston rod 741 is inserted into the exhaust hole 73. An annular groove is formed on the inner wall of the exhaust hole 73, and the spring 743 and the convex ring 744 are slidably arranged inside the annular groove. The convex ring 744 is fixedly connected to the outer wall of the piston rod 741, and the upper end of the convex ring 744 abuts against the spring 743. An inverted L-shaped hole 742 is formed inside the piston rod 741, and the upper and lower ends of the inverted L-shaped hole 742 are respectively formed on the upper outer wall and the lower end face of the piston rod 741.

[0037] In this embodiment, after air or oxygen enters the cavity 72, the air pressure increases and pushes the piston column 741 upward, causing the upper end of the inverted L-shaped hole 742 to rise above the hollow turntable 71, so that the air in the cavity 72 can be released into the cocoa liquor above the hollow turntable 71 through the inverted L-shaped hole 742; when the air intake in the cavity 72 stops and the air pressure is restored, the piston column 741 descends under the action of the spring 743 and lowers the inverted L-shaped hole 742 into the exhaust hole 73, which is blocked by the hollow turntable 71, preventing the cocoa liquor from entering the cavity 72 through the inverted L-shaped hole 742.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
