Abstract
Description
Technical Field
[0001] This utility model belongs to the field of drying equipment, and specifically relates to a high-efficiency automatic circulating drying device. Background Technology
[0002] With the development of society and technology, equipment in various fields has been greatly improved. Various types of drying equipment are often needed in industrial production and daily life. They evaporate and remove the moisture in materials by introducing hot air. They are widely used in the food industry, medicine, construction and other fields. Among them, drying equipment with horizontal plate hot water circulation function can also improve energy utilization, improve material drying efficiency, ensure quality and reduce costs.
[0003] Currently, most drying devices on the market use fans to draw air into the material basket for drying. However, this method results in the material being piled up inside the basket, preventing the material on the inside and bottom from being dried by hot air, leading to low drying efficiency. In addition, fresh air is usually introduced and old air is discharged through an adjustment plate. However, the old air contains a lot of heat, and direct discharge will cause heat damage, resulting in low energy utilization.
[0004] Therefore, the above problems urgently need to be solved. Utility Model Content
[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a high-efficiency automatic circulating drying device, which adopts a layered flat plate heater to improve drying efficiency and heat utilization rate; at the same time, it is equipped with a material cart connected to a material grinding device, so that the material enters and exits the drying device in an integrated operation, which is convenient to operate and ensures that safety and quality are not affected.
[0006] Technical Solution: To achieve the above objectives, this utility model provides a high-efficiency automatic circulating drying device, including a grinding device, a material cart, and a drying assembly; the material cart is located between the grinding device and the drying assembly; the material cart is equipped with several loading trays; the drying assembly includes a drying chamber, a hot water tank, a hot water circulation pump, a condenser, and an ethanol storage tank; the hot water tank is located beside the drying chamber, and a set of water pipes is provided between the two; a hot water circulation pump is provided on one side of the hot water tank; the condenser is located beside the hot water tank and is connected to the exhaust port of the drying chamber through a pipe; the ethanol storage tank is located beside the condenser and is connected to the condenser; the material cart is located on one side of the drying chamber door; the top and four corners of the drying chamber are rounded; several layers of flat plate heaters are provided inside the drying chamber; a drain pipe is provided at the bottom of the drying chamber; and a pressure relief valve is provided on the side of the drying chamber. The organic integration of grinding equipment, material carts, and drying components makes the entire process from grinding to drying smoother, reducing material handling and waiting time in intermediate stages. The rounded corner design at the top of the drying chamber prevents condensate from dripping back onto the material after vaporization during drying, improving drying efficiency. The rounded corners at the four corners of the drying chamber eliminate dead angles and facilitate drainage, making the equipment easy to clean and maintain. Several layers of flat plate heaters inside the drying chamber further improve heat transfer efficiency, ensuring more uniform heating of the material and avoiding localized overheating or uneven drying. The condenser condenses the vapor generated during drying into liquid, which flows through pipes into an ethanol storage tank. This not only recovers the condensate but also reduces environmental pollution and facilitates subsequent treatment and reuse of the condensate.
[0007] Furthermore, the flat plate heater has seven layers. This ensures a more uniform temperature distribution and provides a large-area heat transfer effect.
[0008] Furthermore, the drying chamber is equipped with a drying chamber pressure gauge to provide real-time visual monitoring of the pressure inside the drying chamber.
[0009] Furthermore, the drying chamber has a viewing window on its door. The viewing window facilitates observation of the drying process.
[0010] Furthermore, the grinding equipment is provided with a discharge port; a transfer plate is provided between the discharge port and the receiving tray to ensure that the material will not fall during the transfer process.
[0011] Furthermore, the condenser is equipped with a condenser vacuum gauge; the exhaust pipe connecting the condenser and the drying chamber is equipped with a condenser connection manual valve. The condenser vacuum gauge provides real-time visual monitoring of the vacuum status during drying; the condenser connection manual valve controls the airflow, regulates the flow rate, and facilitates maintenance and inspection.
[0012] Furthermore, the ethanol storage tank is equipped with a vacuum generator; the side of the vacuum generator is connected to the drying chamber via a pipe. The vacuum generator can simultaneously perform vacuuming operations on both the ethanol storage tank and the drying chamber, greatly improving vacuuming efficiency.
[0013] Furthermore, a main control panel is located next to the hot water tank. The main control panel provides integrated control for the drying process, enabling more convenient operation.
[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects:
[0015] 1. This utility model provides a high-efficiency automatic circulating drying device, which adopts a layered flat plate heater to improve drying efficiency and heat utilization rate.
[0016] 2. This utility model provides a high-efficiency automatic circulating drying device, which is equipped with a material cart connected to a material grinding device, so that the material enters and exits the drying device in an integrated manner, making the operation convenient and ensuring that safety and quality are not affected.

[0028] Specifically, a distributed hot water jacket can be added to the outside of the inner wall of the drying chamber 31 to ensure that the inner wall and the internal flat plate heater 311 are heated synchronously, thereby achieving a better drying effect.
[0029] In particular, the bottom of the drying chamber 31 can be configured as a funnel shape, and the drain pipe 312 is located at the lower end of the funnel-shaped outlet. The condensate in the drying chamber 31 is concentrated from the surrounding area to the middle of the bottom and discharged through the drain pipe 312, saving drying time.
[0030] Specifically, the flat plate heater 311 can be designed as a detachable type as an option for easy cleaning.
[0031] Specifically, the door seal of the drying chamber 31 uses a high-temperature resistant mushroom-shaped food-grade silicone rubber sealing strip as a preferred option, which has a long service life and good sealing effect.

The ethanol-containing material is put into the grinding equipment 1 for grinding to obtain an ethanol-containing slurry. The slurry is transferred from the discharge port 11 to the receiving tray 21 by the transfer plate 111, and then transferred to the door of the drying chamber 31 by the material cart 2. The receiving tray 21 is placed inside the drying chamber 31 manually, and the door of the drying chamber 31 is locked.
[0048] During drying, set the target temperature of the hot water tank 32 and turn on the hot water circulation pump 33; confirm that the pressure relief valve 313 is closed and open the condenser connection hand valve 342; observe and confirm that the condenser vacuum gauge 341 reading is ≤ -0.08Mpa and confirm that the vacuum generator 36 is venting normally;
