Description

Technical Field

[0001] This utility model relates to a composite heat source dryer for drying food. Background Technology

[0002] The compound heat source baking and flavoring machine is a type of equipment used for drying food, such as wood ear fungus and tea. Currently, a conventional compound heat source baking and flavoring machine mainly consists of a box containing a single heating wire, a fan, a rack, and an electrical box. Because it only has a single heating wire, the heating is achieved through air convection, which delivers heat energy to the surface of the processed material. This means that the drying characteristic is that the processed material dries from the outside in first, and as the heating time increases, the heat energy is transferred to the interior of the processed material. Therefore, the drying of the processed material is characterized by drying from the outside in, resulting in poor drying efficiency and effect. It may not be able to dry food quickly, thus requiring improvement in drying efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a composite heat source baking and aroma-enhancing machine, and the technical problem to be solved is to optimize the structure of the composite heat source baking and aroma-enhancing machine and improve its drying efficiency and drying quality.

[0004] A composite heat source baking and aroma-enhancing machine includes a housing, a fan, an electrical control box, a first heating element, and a second heating element. The fan is installed on the top of the housing, introducing fresh air and creating an internal circulation of hot air within the housing. The electrical control box is installed on the housing to control the fan, the first heating element, and the second heating element. The first heating element has two sets of heating wires, one set positioned below the fresh air inlet of the housing, and the other set positioned at the fan blade outlet and the hot air path. The fresh air inlet is equipped with a fresh air valve to allow air from outside the housing to enter the housing. The second heating element has a radiating heating plate, which is longitudinally arranged on the side of the housing, directly opposite the shelf inside the housing.

[0005] The box contains a shelf.

[0006] The placement rack works in conjunction with a motor located at the bottom of the box to enable the rack to rotate.

[0007] The fan is an exhaust fan.

[0008] The radiating plates are arranged in two symmetrical groups, each group having three longitudinally arranged radiating plates.

[0009] The top of the enclosure has an exhaust vent.

[0010] The radiant panel is a carbon fiber graphene heating radiant panel.

[0011] The beneficial effects of this utility model are as follows: By configuring two sets of heating wires, when fresh air enters the chamber, the first set of heating wires performs the first heating. When the heated fresh air is about to enter the inner cavity of the chamber, it is heated by the second set of heating wires, thus achieving a second heating. By adding a second set of radiant heating plates to generate radiant heat, the heating form of the processed material is improved, that is, the material absorbs heat energy and is heated simultaneously from the inside and outside, resulting in uniform water loss characteristics and more complete internal transformation, thereby achieving higher drying efficiency and effect. By configuring the above-mentioned dual-layer heating of heating wires and radiant plates, the drying effect can be significantly increased. With the matching rotating rack, all-round drying of food is achieved. Attached Figure Description

[0027] Please refer to Figures 1 to 6 The composite heat source baking and aroma-enhancing machine shown in the figure mainly consists of an electrical box 1, a housing 2, a fan 3, a first heating element 4, a second heating element 5, and other corresponding accessories. This case achieves a good drying effect by configuring the above components. It should be noted that the installation position and model of the above components can be adjusted as needed.

[0028] The box 2 in the figure is a cubic frame structure. An electrical box 1 is installed at the top end, and a fan 3 is located near the center of the top. Components not shown in the figure, such as exhaust valves and fresh air valves controlled by the electrical box 1, are arranged beside it. These valves are equipped with exhaust vents 61 and fresh air vents 62. The box 2 has two internal hollow structures. The top hollow structure facilitates the placement of the fan blades 31, the first heating element 4, and other components. The lower hollow structure facilitates the placement of food to be dried and the second heating element 5, and other components. The inner walls of the second hollow structure are designed with evenly distributed ventilation holes on opposite sides according to the hot air flow path to facilitate hot air flow and food drying. The inner walls of the box 2 require insulation to prevent heat loss. Rollers 21 are installed at the bottom of the box 2 for easy movement. A rotary motor 8 can be installed at the bottom of the box 2 to drive the rotation of the internal rack 7.

[0029] The fan 3 in the figure is a conventional fan 3, such as an exhaust fan 3 or a draft fan 3. Its body is installed on the top and upper part of the box 2, and the blades 31 are installed in the inner cavity of the top of the box 2. The blades 31 cooperate with the fresh air inlet 62 when the fresh air valve is open to introduce fresh air into the box 2. In addition, when the fresh air valve is closed, the blades 31 can realize the internal circulation of hot air in the box 2.

[0030] The electrical box 1 in the figure can be an existing control box 1, which provides real-time control of various components such as the fan 3, the first heating group 4, the second heating group 5, and various operating conditions. The aforementioned electrical box 1 is not an innovative design feature of this case.

[0031] The first heating element 4 in the diagram is designed with two sets of heating wires 41. One set of heating wires 41 is positioned directly below the fresh air inlet 62 to provide the first stage of convection heating for the fresh air entering the chamber 2. The second set of heating wires 41 is positioned at the air outlet of the blades 31 and along the hot air path, thus providing a second stage of convection heating for the air. The number and power of the heating wires 41 can be selected according to the specific type of food to be dried and the drying conditions.

[0032] The second heating element 5 in the diagram is designed with carbon fiber and graphene radiant heating panels, which are installed longitudinally on the back of the housing 2. Specifically, they are installed on the left and right sides of the back, with three radiant panels 51 on each side installed longitudinally and facing the rack 7. Their height exactly covers the height of the rack 7 to achieve good drying. In practical applications, other radiant panels suitable for this equipment can also be selected.

[0033] In practical applications, the above components can be further optimized, such as by optimizing the number and arrangement of the two heating elements.
