Description

Technical Field

[0001] This utility model relates to the technical field of cooking equipment, and in particular to a multi-layer cooking machine. Background Technology

[0002] Traditional cooking equipment often employs a single-layer cage structure, resulting in low space utilization and uneven heating of the material. Furthermore, existing cooking devices typically use a single-sided heating element, leading to a significant temperature gradient within the chamber, which is detrimental to centralized and uniform cooking of the product. Additionally, the presence of only one stirring structure can easily result in overheating at the bottom while the top remains underheated. Therefore, to address the problems of existing technology, this invention proposes a multi-layer cooking machine that facilitates centralized cooking. Utility Model Content

Detailed Implementation

[0026] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1-5 As shown, the multi-layer cooking machine of this utility model includes a cooking chamber 1. The interior of the cooking chamber 1 has at least two parallelly installed material-bearing cages 82. Each material-bearing cage 82 includes a base 821, a material-separating baffle 822 disposed around the base 821, and a hinged cover 823 hinged to one side of the material-separating baffle 822. The base 821, the material-separating baffle 822, and the hinged cover 823 are all provided with water inlets. Several material-bearing cages 82 are connected by a hanging rod 8. The hanging rod 8 extends from the bottommost material-bearing cage 82 upwards to the topmost material-bearing cage 82. The top of the hanging rod 8... The unit is equipped with a hook 81. For easy assembly, the flip cover 823 is a two-piece design. The two flip covers 823 have a clearance hole in the middle to facilitate the passage of the lifting rod 8. The two flip covers 823 are mounted on a hinge rod 824, which is located on the upper side of the material separator baffle 822. During assembly, the hook 81 is suspended on a hanging rod inside the cooking chamber 1. The top of the cooking chamber 1 is equipped with an air vent 2 and an overflow vent 3. The bottom of the cooking chamber 1 is equipped with a water outlet pipe 5, which is equipped with a switch valve. The bottommost material cage 82 is located above the connecting pipe 42.

[0028] The cooking chamber 1 is equipped with a heating assembly 4. The heating assembly 4 includes a first heat exchange rod 41 disposed on one side of the chamber wall and a second heat exchange rod 43 disposed on the other side of the chamber wall. The first heat exchange rod 41 and the second heat exchange rod 43 are connected by a serpentine connecting pipe 42. The interiors of the first heat exchange rod 41, the second heat exchange rod 43 and the connecting pipe 42 are hollow and interconnected. The second heat exchange rod 43 is connected to an external steam delivery pipe 44. In order to facilitate the control of the amount of steam entering, a solenoid valve 45 is provided on the steam delivery pipe 44. The delivery section of the steam delivery pipe 44 passes through and is fixed in the limiting ring 46 at the bottom of the cooking chamber 1.

[0029] A first motor 6 is provided on the lower outer side of the cooking chamber 1. The first motor 6 is connected to a first rotating shaft 61 vertically arranged inside the cooking chamber 1. First stirring rods 62 are evenly distributed on the first rotating shaft 61. After assembly, the first stirring rods 62 are arranged between the first heat exchange rod 41 and the material support cage 82.

[0030] A second motor 7 is provided on the upper outer side of the cooking chamber 1. The second motor 7 is connected to a second rotating shaft 71 inside the cooking chamber 1. A second stirring rod 72 is provided around the circumference of the second rotating shaft 71. After assembly, the second stirring rod 72 is positioned between the second heat exchange rod 43 and the material cage 82. The second motor 7 is fixedly installed on the support platform 73 on the outer side of the cover of the cooking chamber 1.

[0031] Before operation, the materials are distributed into different receiving cages. The hooks on the lifting rods are then fastened to the hanging rods inside the cooking chamber. The chamber lid is then closed from top to bottom and locked in place. During operation, steam is introduced into the second heat exchanger through the conveying pipe, forming a circulating heating system through a serpentine connecting pipe. The steam is also directed towards the first heat exchanger, creating a three-dimensional circulating heating field inside the entire chamber. Driven by the first motor, the first stirring rod generates an upward water flow between itself and the heating components, while the second stirring rod descends under the drive of the second motor. The water flow forms a closed-loop convection, allowing heat to diffuse evenly within the water, which is beneficial for heating the material. The permeable design of the material cage allows the high-temperature water flow to penetrate the material layer. The hinged flap remains sealed during cooking, preventing material leakage. It should be noted that during assembly, the flap is pressed into the groove of the material baffle on the other side for locking, and this locking mechanism is existing technology. When processing different amounts of material, the cooking space can be adjusted by setting the number of material cages, forming multi-layered, concentrated, and uniform cooking. After the operation is completed, the hoisting assembly can be lifted out as a whole for unloading.

[0032] The embodiments described above are merely preferred embodiments of the present invention, and are described in a relatively specific and detailed manner. However, the present invention is not limited to these embodiments. It should be noted that for those skilled in the art, any improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
