Description

Technical Field

[0001] This utility model relates to a medium-fire roasting and stabilization device for grains and their products, belonging to the technical field of grain and product processing equipment. Background Technology

[0002] To improve the nutritional and taste quality of grains and related products, or to enhance the quality stability of grains and related products, roasting and stabilization processes are frequently used during the processing of grains and related products.

[0003] Existing technologies typically use methods such as baking and microwaves. For example, CN201820745081.1 discloses a microwave drying device for powders. However, during the powder drying process, the powder is basically in a relatively static state, and the upper and lower layers of the powder are heated unevenly. This leads to the problem of unstable degree of ripening and poor uniformity in the baking and stabilization process of grains and products, resulting in fluctuations in product nutrition and taste quality, poor stability, and high equipment wear. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a medium-fire roasting and stabilization device for grains and products, which addresses the shortcomings of the existing technology. By setting up protrusions under the conveyor belt, the material can be turned over during the conveying process, so that the material is heated evenly, preventing the material from scorching, compensating for the unevenness of the upper and lower layers and the lateral side of the material, and increasing the lateral uniformity of the fabric, thereby improving the quality of the product.

[0005] The technical problem to be solved by this utility model is achieved through the following technical solution:

[0006] This utility model provides a medium-fire roasting and stabilization device for grains and their products. The medium-fire roasting and stabilization device for grains and their products includes a microwave heating device, a material conveying device that passes through the microwave heating device, a dehumidification device, and a control device. The material conveying device includes a conveyor belt, a drive motor that drives the conveyor belt, and a plurality of protrusions arranged at intervals below the conveyor belt. The plurality of protrusions are arranged at intervals along the material conveying direction.

[0007] Preferably, the microwave heating device includes a microwave heating chamber and a plurality of microwave generators arranged horizontally within the microwave heating chamber.

[0008] To facilitate observation of the baking process, at least one visible oven door is provided on the microwave heating chamber.

[0009] Preferably, the distance between adjacent bosses is 30cm, the height of the boss is 20cm, and the cross-section of the boss is triangular.

[0010] Preferably, the angle between the side of the boss and the conveyor belt is 45° to 60°.

[0011] To facilitate the placement of materials on the material conveying device, a buffer hopper is provided at the feed end of the material conveying device.

[0012] To improve dehumidification efficiency, the air extraction port of the dehumidification device is located at the feed inlet of the microwave heating chamber.

[0013] In summary, by setting protrusions under the conveyor belt, this utility model can stir-fry the material during the conveying process, making the material heat evenly, preventing the material from scorching, compensating for unevenness between the upper and lower layers and in the lateral direction of the material, and also increasing the lateral uniformity of the fabric, thereby improving the quality of the product.

[0014] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the fire roasting and stabilization equipment for grains and their products according to this utility model;

[0016] Figure 2 This is a schematic diagram of the structure of the transmission belt and the boss of this utility model. Detailed Implementation

[0017] Figure 1 This is a schematic diagram of the fire roasting and stabilization equipment for grains and their products according to this utility model; Figure 2 This is a schematic diagram of the conveyor belt and boss of this utility model. Figure 1 and Figure 2 As shown, the grain and product roasting and stabilization equipment of this utility model includes a microwave heating device 100, a material conveying device 200 passing through the microwave heating device 100, a dehumidification device (not shown in the figure), and a control device 300. The control device 300 is electrically connected to the microwave heating device 100, the material conveying device 200, and the dehumidification device, and is used to control the operation of the microwave heating device 100, the material conveying device 200, and the dehumidification device.

[0018] The microwave heating device 100 includes a microwave heating chamber and a plurality of microwave generators arranged horizontally within the microwave heating chamber. The control device 300 can, for example, control the microwave output intensity of the microwave generators based on the temperature inside the microwave heating chamber, and can also control the conveying speed of the material conveying device 200 and the dehumidification power of the dehumidification device, etc.

[0019] To ensure thorough cooking of grains and products, the length of the microwave heating chamber can be designed as needed. To avoid the microwave heating chamber becoming too long and difficult to transport and install, the microwave heating chamber can be composed of multiple sub-chambers horizontally connected, with connection methods including, but not limited to, flange connections. Figure 1 As shown in the figure, an example of a microwave heating chamber consisting of five sub-chambers is presented.

[0020] This invention does not limit the type and structure of the microwave generator, and those skilled in the art can design and select according to actual needs. For example, existing Boda microwave equipment can be used, with a microwave frequency of 2450±50MHz and a microwave power of 20KW (adjustable), or the continuous microwave drying and sterilization equipment of Hunan Weilang Technology Co., Ltd. can be used. Since the microwave generator is existing technology, it will not be described in detail here.

[0021] To reduce power loss in the microwave generator, the microwave generator of this invention preferably adopts a multi-port direct feed method. The broadband top-down microwave feed, combined with precise network analysis and design, allows the material to directly receive electromagnetic field energy, thereby improving heating efficiency.

[0022] The dehumidification device is used to extract water vapor generated inside the microwave heating chamber during the baking process. This dehumidification device is also existing technology and will not be described in detail here. It should be noted that, based on the direction of moisture vaporization, this invention preferably adopts an inlet-end dehumidification method, that is, the air extraction port of the dehumidification device is located at the feed inlet of the microwave heating chamber. Figure 1 (on the left side of the microwave heating device 100), thereby increasing the heat utilization rate and improving the dehumidification efficiency.

[0023] To prevent damage to electrical components caused by harsh environments and high voltage, and to ensure the long-term stable operation of each component and continuous production of the equipment, the interfaces of all electrical components in this invention are preferably sealed by welding or casting.

[0024] The material conveying device 200 includes a conveyor belt 210, a drive motor for driving the conveyor belt 210, and a plurality of protrusions 230 disposed below the conveyor belt 210, the plurality of protrusions 230 being spaced apart along the material conveying direction. The portion of the conveyor belt 210 located above the plurality of protrusions 230 is respectively lifted up.

[0025] The material of the conveyor belt 210 can be polytetrafluoroethylene or the like, and the drive motor drives the conveyor belt 210 to transport materials, for example, through a crawler-type drive. Figure 1 The arrows in the diagram indicate the direction of material transport.

[0026] Unlike traditional conveyor belts, in this invention, the conveyor belt 210 has multiple protrusions 230 below it. Because of these protrusions 230, during the movement of the conveyor belt 210, a portion of the conveyor belt 210 is lifted by the protrusions 230, changing its height. At this time, the material located in that portion moves under the influence of gravity and the support of the conveyor belt 210, thus achieving material turning.

[0027] Preferably, the distance between adjacent protrusions 230 is 30cm, the height of the protrusion 230 is 20cm, and the cross-section of the protrusion 230 can be an isosceles triangle, etc.

[0028] When the cross-section of the boss 230 is an isosceles triangle, the angle (base angle of the isosceles triangle) between the side of the boss 230 and the conveyor belt 210 is 45° to 60°. This invention is not limited to this; those skilled in the art can design and select the shape and size of the boss according to the type of material, etc. For example, the boss can also be trapezoidal, semi-circular, etc.

[0029] To facilitate the placement of materials on the material conveying device 200, a buffer hopper 201 is provided at the feed end of the material conveying device 200.

[0030] To prevent materials such as beans from being ejected during discharge, the discharge end of the material conveying device 200 is equipped with a discharge baffle and other bulletproof structures.

[0031] To facilitate observation of the baking process, at least one visible oven door 110 is provided on the microwave heating chamber, and the visible oven door 110 is at least partially made of a transparent material (such as glass).

[0032] The working process of this utility model will be explained below with specific examples.

[0033] Grains and their products fall onto the conveyor belt through the buffer hopper and are then transported to the microwave heating device. Because there are multiple protrusions under the conveyor belt, these protrusions lift up the portion of the conveyor belt above them, making the conveyor belt into a wave-like shape. The grains and their products tumble on the conveyor belt, thus allowing them to be roasted more evenly.

[0034] It should be noted that the grain and product roasting and stabilization equipment disclosed in this utility model can also be used to roast other materials.

[0035] In summary, by setting protrusions under the conveyor belt, this utility model can stir-fry the material during the conveying process, making the material heat evenly, preventing the material from scorching, compensating for unevenness between the upper and lower layers and in the lateral direction of the material, and also increasing the lateral uniformity of the fabric, thereby improving the quality of the product.
