Description

Technical Field

[0001] This utility model relates to the technical field of dried bean curd processing equipment, specifically a dried bean curd drying equipment. Background Technology

[0002] Tofu skin, a traditional soy product, is loved by consumers. Drying is a crucial step in the production process, directly affecting its quality, texture, and shelf life. Tofu skin drying equipment replaces the traditional sun-drying method, freeing the tofu skin from environmental influences and preventing contamination from outdoor dust.

[0003] However, traditional tofu skin drying equipment typically uses a heat pump to heat the air, and then a motor blows hot air onto the side of the tofu skin for drying. This method can cause one side of the tofu skin to be subjected to greater airflow, leading to localized stress during the drying process. This can easily cause problems such as deformation, cracking, or wrinkling. Furthermore, the heating method is singular, and when the ambient temperature is too low, the heat pump's heating efficiency decreases, affecting the drying efficiency. Additionally, the water vapor evaporated from the heated tofu skin is directly discharged from the drying equipment through a dehumidifier, meaning the residual heat inside is not fully utilized, resulting in energy waste.

[0004] To address the aforementioned problems, this application proposes a dried bean curd drying device. Utility Model Content

[0005] The purpose of this utility model is to provide a dried bean curd drying device to solve the problems of uneven drying of dried bean curd, single heating method of drying equipment, and insufficient utilization of heat energy in the prior art mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dried bean curd drying device, comprising a drying chamber, a control component fixedly installed on the front outer surface of the drying chamber, a sealing door movably installed on one outer surface of the drying chamber, an air guide plate fixedly installed on the inner side of the drying chamber, multiple sets of ventilation holes evenly opened on the upper outer surface of the air guide plate, and an air guide cavity formed by the air guide plate and the upper inner surface of the drying chamber, and an air supply pipe and a heating pump fixedly installed on the other side of the drying chamber, the upper end of the air supply pipe being connected to the air guide cavity, and the lower end being connected to the heating pump.

[0007] Preferably, a dehumidification hole is provided on the inner surface of the other side of the drying chamber, the dehumidification hole is connected to a dehumidification pipe, and the other end of the dehumidification pipe is connected to a dehumidification fan located on the other side of the drying chamber.

[0008] Preferably, a condensing device is fixedly installed at the upper end of the dehumidifying fan, and a hot air pipe is fixedly connected to the upper end of the condensing device. The other end of the hot air pipe is connected to a heating pump.

[0009] Preferably, a water outlet pipe is fixedly installed at the front end of the dehumidification fan.

[0010] Preferably, an infrared heating tube and a protective frame are fixedly installed at the lower end of the air guide plate, the infrared heating tube is located between the air guide plate and the protective frame, and a protective net is fixedly installed on the inner side of the protective frame.

[0011] Preferably, an insulation board is fixedly installed inside the interlayer of the drying chamber.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses a heating pump to heat the outside air, and then uses an internal fan to transport the hot air through an air duct to the air guide cavity. The hot air in the air guide cavity flows vertically downward through the ventilation holes at the top of the air guide plate. The hot air can vertically and relatively evenly cover the entire surface of the dried bean curd stick, so that the heat received by each part of the dried bean curd stick is basically the same. This reduces the situation of local over-drying or local under-drying caused by uneven heat distribution, and can better ensure the consistency of the overall drying effect of the dried bean curd stick.

[0014] This invention uses a dehumidifying fan to draw the water vapor from the heated tofu skin into the dehumidifying pipe through the dehumidifying hole, and finally to the condensing device. The condensed water can be discharged through the water outlet pipe, while the remaining hot air will enter the heating pump through the hot air pipe for recycling, so that the heat can be fully utilized and energy waste can be reduced.

[0015] This invention utilizes an infrared heating tube to ensure that when the ambient temperature is too low and the heating efficiency of the heating pump decreases, the airflow with lower heat will first pass through the surface of the infrared heating tube when it enters the drying chamber through the ventilation holes. The infrared heating tube can then further heat the airflow, thereby improving the drying efficiency of the dried bean curd sticks. Attached Figure Description

Detailed Implementation

[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] Please see Figures 1-5 This utility model provides a technical solution: a dried bean curd drying device, comprising a drying chamber 1, a control component 2 fixedly installed on the front outer surface of the drying chamber 1, a sealing door 3 movably installed on one outer surface of the drying chamber 1, an air guide plate 4 fixedly installed on the inner side of the drying chamber 1, multiple sets of ventilation holes 5 evenly opened on the upper outer surface of the air guide plate 4, and an air guide cavity 6 formed by the air guide plate 4 and the upper inner surface of the drying chamber 1, and an air supply pipe 7 and a heating pump 8 fixedly installed on the other side of the drying chamber 1, the upper end of the air supply pipe 7 and the air guide plate 7 are connected to the air guide plate 4. The air chamber 6 is connected to the heating pump 8 at its lower end. The heating pump 8 heats the outside air, and the internal fan then transports the hot air to the air chamber 6 through the air duct 7. The hot air in the air chamber 6 flows vertically downward through the ventilation hole 5 at the upper end of the air guide plate 4. The hot air can vertically and relatively evenly cover the entire surface of the bean curd stick, so that the heat received by each part of the bean curd stick is basically the same. This reduces the situation of local over-drying or local under-drying caused by uneven heat distribution, and can better ensure the consistency of the overall drying effect of the bean curd stick.

[0024] In this embodiment, as Figures 1-4As shown, a dehumidification hole 9 is provided on the inner surface of the other side of the drying chamber 1. The dehumidification hole 9 is connected to the dehumidification pipe 10. The other end of the dehumidification pipe 10 is connected to the dehumidification fan 11 located on the other side of the drying chamber 1. A condenser 12 is fixedly installed at the upper end of the dehumidification fan 11. A hot air pipe 13 is fixedly connected to the upper end of the condenser 12. The other end of the hot air pipe 13 is connected to the heating pump 8. A water outlet pipe 14 is fixedly installed at the front end of the dehumidification fan 11. When the dried bean curd is heated by hot air, the moisture on its surface will evaporate. The water vapor will enter the dehumidification pipe 10 through the dehumidification hole 9 under the action of the dehumidification fan 11, and finally enter the condenser 12. The condensed water can be discharged through the water outlet pipe 14, while the residual hot air inside will enter the heating pump 8 through the hot air pipe 13 for recycling, so that the heat can be fully utilized and energy waste is reduced.

[0025] In this embodiment, as Figure 3 Figure 5 As shown, an infrared heating tube 15 and a protective frame 16 are fixedly installed at the lower end of the air guide plate 4. The infrared heating tube 15 is located between the air guide plate 4 and the protective frame 16. A protective net 17 is fixedly installed on the inner side of the protective frame 16. An insulation board 18 is fixedly installed in the interlayer of the drying chamber 1. When the ambient temperature is too low and the heating efficiency of the heating pump 8 decreases, the infrared heating tube 15 can be activated for heating. When the airflow with low heat enters the drying chamber through the ventilation hole 5, it will first pass through the surface of the infrared heating tube 15. The infrared heating tube 15 can further heat the airflow, thereby avoiding the impact of the reduced heating efficiency of the heating pump 8 on the drying efficiency of the dried bean curd. The insulation board 18 is made of aluminum silicate fiber, which has the characteristics of high temperature resistance and low thermal conductivity, which can effectively reduce heat loss. It also has strong chemical stability and will not cause pollution to the dried bean curd. The infrared heating tube 15 can be protected by the protective net 17 in the protective frame 16 without affecting the flow of gas.

[0026] Working principle:

[0027] When using the dried bean curd drying equipment, the drying rack with the bean curd hanging on it is first pushed into the equipment. The heating pump 8 is then started via the control component 2. The heating pump 8 draws in and heats air from the outside. The fan inside the heating pump 8 then transports the hot air through the air duct 7 to the air guide chamber 6. The hot air in the air guide chamber 6 flows vertically downwards through the ventilation holes 5 at the top of the air guide plate 4, ensuring that the hot air vertically and evenly covers the entire surface of the bean curd. As the bean curd is heated by the hot air, the surface moisture evaporates. The water vapor, under the action of the dehumidification fan 11, enters the dehumidification pipe 10 through the dehumidification hole 9, and finally enters the condensation device 12. The condensed water is discharged through the water outlet pipe 14, while the remaining hot air is recycled back into the heating pump 8 through the hot air pipe 13. When the ambient temperature is too low and the heating efficiency of the heating pump 8 decreases, the infrared heating tube 15 can be activated for heating. When the airflow with low heat enters the drying chamber through the ventilation hole 5, it will first pass through the surface of the infrared heating tube 15. The infrared heating tube 15 can further heat the airflow, thereby improving the drying efficiency of the dried bean curd sticks.

[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
