Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of biscuit production equipment, specifically to a drying device for tomato biscuit production. Background Technology

[0002] In the production of tomato biscuits, the drying process is a crucial step that determines the product's taste, shelf life, and quality, and the performance of the equipment directly impacts production efficiency and product quality. However, traditional tomato biscuit drying equipment has many technical shortcomings, making it difficult to meet the demands of modern food processing for efficient, energy-saving, and clean production.

[0003] Currently, most drying equipment relies on a single electric dryer to heat and dry biscuits. This drying method mainly depends on the conversion of electrical energy into heat energy, which not only has extremely high energy consumption, leading to increased production costs, but also results in uneven heat distribution, easily causing localized overheating or insufficient drying. This results in inconsistent color and taste of the tomato biscuits, seriously affecting product quality. Furthermore, single-electric drying lacks a heat recovery and recycling mechanism, with a large amount of heat being discharged with exhaust gases, causing significant energy waste and contradicting the concept of green production. In addition, this type of equipment has low drying efficiency; the long drying process not only extends the production cycle but also limits capacity expansion, making it difficult to meet the needs of large-scale production.

[0004] On the other hand, the conveyor system of traditional drying equipment has significant drawbacks. During the drying process, crumbs, residues, and other impurities easily fall off and adhere to the conveyor belt surface. As the drying process progresses, these impurities carbonize and deteriorate, producing odors and releasing harmful gases. When subsequent biscuits come into contact with the conveyor belt containing these impurities, they will not only be contaminated, affecting hygiene and safety, but the impurities may also cause uneven heating, further reducing drying quality. Existing equipment lacks an effective impurity cleaning mechanism, requiring frequent machine shutdowns for manual cleaning, which increases labor intensity and reduces equipment operating rate, becoming a major bottleneck restricting the efficiency and quality improvement of tomato biscuit production. Therefore, the development of new, efficient, energy-saving, and clean tomato biscuit drying equipment is urgently needed. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a drying equipment for tomato biscuit production, which solves the technical problems of the prior art, which mainly relies on the conversion of electrical energy into heat energy, resulting in extremely high energy consumption and increased production costs, as well as uneven heat distribution, which easily leads to local overheating or insufficient drying.

[0006] According to one aspect, at least one embodiment of this disclosure provides a drying apparatus for producing tomato biscuits, comprising:

[0007] The housing and a pair of inlets and outlets, which are respectively opened on the two side surfaces of the housing;

[0008] A conveying assembly disposed inside the housing;

[0009] A circulating heating assembly is disposed within the housing;

[0010] The circulating heating assembly includes an air box, which is fixed to the top of the outer shell. Several first heating tubes are arranged inside the air box. Both ends of the top of the outer shell are provided with air circulation covers, which are connected to the air box. Several second heating tubes are arranged inside the top of the outer shell.

[0011] As a further technical solution, a high-temperature resistant fan is installed in the pipe connecting the air hood and the air box, and several dispersing pipes are connected between the air hoods, with several air holes opened on the inner surface of the dispersing pipes.

[0012] As a further technical solution, the conveying assembly includes a plurality of support rollers, all of which are disposed at both ends inside the housing, and a conveyor belt is fitted around the outside of the support rollers.

[0013] As a further technical solution, a pair of drive rollers are rotatably connected inside the housing, one of which is controlled to rotate by a motor. The upper surface of the drive roller is in contact with the surface of the conveyor belt, and the drive roller is located directly below the bottom support roller.

[0014] As a further technical solution, a feed plate is installed in the inlet and outlet on one side, and a discharge hopper is provided in the inlet and outlet on the other side, with both the feed plate and the discharge hopper having a certain inclination angle.

[0015] As a further technical solution, the overall shape of the dispersing pipe is close to a circular ring structure, and the dispersing pipe surrounds the top periphery of the conveyor belt.

[0016] As a further technical solution, elongated holes are provided on both sides of the outer shell, and the elongated holes are located at the lowest end of the side surface of the outer shell.

[0017] As a further technical solution, the distribution range of the plurality of the dispersed pipes is close to the overall length of the conveyor belt.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. In this disclosure, the circulating heating component achieves efficient and energy-saving drying through hot air circulation and dispersed heat distribution. The first heating tube in the air box and the second heating tube at the top of the outer shell work together to heat the air. A high-temperature resistant fan drives the hot air to circulate in the air box, the air hood, and the dispersion pipe. The dispersion pipe surrounds the top of the conveyor belt, and its air holes blow the hot air evenly onto the biscuits. The heat that is not absorbed is returned to the air box for heating and utilization. Compared with the traditional single heating method, heat waste is reduced, energy utilization is improved, local overheating or insufficient drying is avoided, the biscuits are heated evenly, and the quality and drying efficiency are improved.

[0020] 2. In this disclosure, the conveying assembly ensures stable biscuit conveying by means of a drive structure and inclined design. The support roller supports the conveyor belt, and the motor drives the drive roller to drive the conveyor belt to run smoothly. The drive roller is located directly below the bottom support roller to enhance the driving effect and prevent slippage and deviation. The inclined feed plate and discharge hopper use gravity to assist the biscuits in entering and exiting the equipment. The feed plate allows the biscuits to enter in an orderly manner to avoid accumulation, and the discharge hopper quickly receives the dried biscuits, reducing the dwell time and ensuring continuous and efficient operation of the equipment to meet the needs of large-scale production.

[0027] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0028] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0030] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-4 As shown, a drying apparatus for producing tomato biscuits according to an embodiment of the present disclosure is illustrated, comprising:

[0034] The outer casing 1 and a pair of inlets and outlets 2 are respectively opened on both sides of the outer casing 1;

[0035] Conveying assembly 4, which is disposed inside the housing 1;

[0036] A circulating heating component 3 is disposed in the outer casing 1;

[0037] The circulating heating component 3 includes an air box 3-1, which is fixed to the top of the outer shell 1. Several first heating tubes 3-2 are arranged inside the air box. Both ends of the top of the outer shell 1 are provided with air circulation hoods 3-3, which are all connected to the air box 3-1. Several second heating tubes 3-4 are arranged inside the top of the outer shell 1. High-temperature resistant fans 3-5 are arranged in the pipes connecting the air circulation hoods 3-3 and the air box 3-1. Several dispersing pipes 3-6 are connected between the air circulation hoods 3-3, and several air holes 3-7 are opened on the inner surface of the dispersing pipes 3-6.

[0038] In some examples, a circulating heating component 3 is designed to achieve efficient and uniform drying. The first heating tube 3-2 inside the air chamber 3-1 and the second heating tube 3-4 at the top of the outer casing 1 work together to heat the air to a suitable temperature. After the high-temperature resistant fan 3-5 is activated, forced convection is created between the air chamber 3-1 and the air hood 3-3, allowing hot air to circulate continuously through the dispersion pipe 3-6. The evenly distributed air holes 3-7 on the inner surface of the dispersion pipe 3-6 disperse the hot air at a specific angle and flow rate, ensuring that the hot air evenly covers the tomato biscuits on the conveyor belt 4-2. During the circulation of hot air within the outer casing 1, any unabsorbed heat returns to the air chamber 3-1 for reheating and reuse, significantly improving energy efficiency compared to traditional single-heating methods. Through the circulating flow of hot air and the precise heat distribution of the dispersion pipe 3-6, this component effectively avoids localized overheating or uneven drying, ensuring that the tomato biscuits are heated evenly throughout the drying process, thus improving product quality and drying efficiency.

[0039] like Figures 1-4 As shown in the figure, the conveying assembly 4 in this embodiment includes several support rollers 4-1, which are all disposed at both ends inside the outer shell 1. A conveyor belt 4-2 is fitted around the support rollers 4-1. A pair of drive rollers 4-3 are rotatably connected inside the outer shell 1. One of the drive rollers 4-3 is controlled to rotate by a motor. The upper surface of the drive roller 4-3 is in contact with the surface of the conveyor belt 4-2. The drive roller 4-3 is located directly below the bottom support roller 4-1. A feed plate 4-4 is installed in the inlet / outlet 2 on one side, and a discharge hopper 4-5 is provided in the inlet / outlet 2 on the other side. The feed plate 4-4 and the discharge hopper 4-5 both have a certain inclination angle.

[0040] In some examples, a conveyor assembly 4 is designed to ensure stable feeding and discharging of tomato biscuits. Support rollers 4-1 at both ends inside the outer casing 1 provide stable support for the conveyor belt 4-2. A motor drives one of the drive rollers 4-3 to rotate, and friction drives the conveyor belt 4-2 to run smoothly. The layout of the drive roller 4-3 directly below the bottom support roller 4-1 enhances the driving effect on the conveyor belt 4-2, ensuring no slippage or deviation during the conveying process. An inclined feed plate 4-4 and a discharge hopper 4-5 utilize gravity to assist the biscuits in automatically sliding into and out of the equipment. The feed plate 4-4 ensures that the biscuits enter the conveyor belt 4-2 in an orderly manner, avoiding accumulation and blockage; the discharge hopper 4-5 quickly receives the dried biscuits, reducing dwell time. This structural design not only ensures stable feeding and discharging of tomato biscuits during the drying process but also optimizes the feeding and discharging process, enabling the equipment to operate continuously and efficiently, meeting the needs of large-scale production.

[0041] For example, such as Figure 4 As shown, the overall shape of the dispersing pipe 3-6 is close to a circular structure, and the dispersing pipe 3-6 surrounds the top periphery of the conveyor belt 4-2.

[0042] In some examples, the near-annular structure allows the dispersing pipes 3-6 to fully surround the conveyor belt 4-2, maximizing the temperature coverage around the biscuits and achieving better drying results.

[0043] For example, such as Figure 1 As shown, elongated holes 5 are provided on both sides of the outer shell 1, and the elongated holes 5 are located at the lowest end of the side surface of the outer shell 1.

[0044] In some examples, by providing an elongated hole 5, cookie crumbs can be blown out through the hole 5 by airflow, making cleaning easier and preventing internal accumulation.

[0045] For example, such as Figure 3 As shown, the distribution range of several of the dispersed pipes 3-6 is close to the overall length of the conveyor belt 4-2.

[0046] In some examples, the dispersing pipes 3-6 are laid out according to the length of the conveyor belt 4-2, ensuring that the temperature evenly covers the biscuits conveyed on the conveyor belt 4-2. The dispersing pipes 3-6 are closely arranged along the longitudinal direction of the conveyor belt 4-2, their distribution almost covering the entire length of the conveyor belt, ensuring that each tomato biscuit is within the effective hot air zone during conveying. The air vents on the pipes are precisely calculated and arranged, using a staggered opening design to ensure that the hot air blown from adjacent pipes forms a cross-over heat flow layer above the conveyor belt. As the biscuits move with the conveyor belt, regardless of their position, they will be evenly baked by hot air from different angles. This layout avoids the problem of uneven drying of biscuits caused by the lack of hot air coverage in some areas of traditional drying equipment, significantly improving the uniformity and quality stability of tomato biscuit drying, and effectively ensuring product quality consistency.

[0047] In actual use: After fixing the outer shell 1, inlet and outlet 2 are opened on both sides of the outer shell 1. The conveyor assembly 4 is installed inside the outer shell 1. The support rollers 4-1 are set at both ends inside the outer shell 1. The conveyor belt 4-2 is fitted on the outside. The drive roller 4-3 is rotatably connected inside the outer shell 1. One of the drive rollers 4-3 is controlled to rotate by a motor. Inclined feed plates 4-4 and discharge hoppers 4-5 are respectively installed at the inlet and outlet 2. The circulating heating assembly 3 is installed in the outer shell 1. The air box 3-1 is fixed on the top of the outer shell 1. The first heating pipe 3-2 is set inside. The two ends of the top of the outer shell 1 are set with air hoods 3-3 and connected to the air box 3-1. The air hoods 3-3 are connected to each other in a dispersed manner. Pipe 3-6 has air holes 3-7 on its inner surface and a high-temperature fan 3-5 inside. A second heating tube 3-4 is installed at the top inside the outer shell 1. When in use, tomato biscuits enter through the inlet 2 via the feed plate 4-4. The drive roller 4-3 drives the conveyor belt 4-2 to transport the biscuits. The first heating tube 3-2 and the second heating tube 3-4 heat the air. The high-temperature fan 3-5 makes the hot air circulate between the air box 3-1 and the air hood 3-3. The hot air is evenly blown onto the biscuits through the air holes 3-7 of the dispersing pipe 3-6. The hot air is recycled. The dried biscuits are discharged from the inlet 2 through the discharge hopper 4-5. The long holes 5 on both sides of the outer shell 1 can discharge the crumbs.
