Abstract
Description
Technical Field
[0001] The utility model relates to the field of vacuum drying ovens, in particular to a vacuum pharmaceutical drying oven. Background Art
[0002] The vacuum pharmaceutical drying oven is a drying equipment designed for the pharmaceutical industry. It creates a vacuum environment, reduces air pressure, and evaporates water under low pressure, thereby accelerating the drying of items. The equipment is widely used in the fields of biochemistry, chemical pharmaceuticals, medical care, agricultural research, and environmental protection. It is particularly suitable for powder drying, baking, and efficient drying of heat-sensitive, easily decomposable, easily oxidized substances and items with complex components.
[0003] However, the pharmaceutical vacuum drying oven faces some challenges in practical application. First, the high vacuum environment leads to reduced heat transfer efficiency, making the material and the placement plate temperature higher. After the drying is completed, this high temperature state still exists, so special care must be taken when removing the material to avoid burns or damage to the material.
[0004] Secondly, due to the high temperature of the material and the placement plate, the discharge process requires a special structure, and high temperature resistant gloves, clamps and other tools are often required, which not only increases the complexity of the operation, but also increases the operation time and cost. Therefore, in practical applications, these factors need to be considered comprehensively to ensure the smooth progress of the drying process. Utility Model Content
[0005] The main purpose of the utility model is to provide a vacuum pharmaceutical drying box, which can effectively solve the problems raised in the background technology.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0024] like Figure 1 - Figure 5 As shown, a vacuum pharmaceutical drying oven mainly includes several key parts, namely, a box body 1, a sealed door 2, a vacuum drying chamber 3, a locking device 4, an instrument 5 and a control panel 6. Among them, the sealed door 2 is flexibly mounted on the box body 1 through a hinge device, and its tightness when closed is ensured by the locking device 4, so as to maintain the vacuum environment inside the drying oven. The vacuum drying chamber 3 is located in the inner cavity of the box body 1, which is the core area for drying pharmaceutical materials. The instrument 5 and the control panel 6 are respectively located at the top and the bottom of the front end of the box body 1, so that users can monitor and adjust the drying process in real time.
[0025] In order to ensure the stability and uniformity of the pharmaceutical materials during the drying process, the chamber wall of the vacuum drying chamber 3 is provided with a plurality of limit frames 7, which are evenly spaced and have a "U"-shaped cross section to provide a stable support. A limit support frame 8 is installed on each limit frame 7, and the top view of these frames is in a "mouth"-shaped design, and a straight bar is provided at the front end of the hole wall for installing a hinge assembly 9. Through the hinge assembly 9, the movable placement plate 10 can be flexibly connected to the limit support frame 8 and set up in the frame.
[0026] In order to further improve the stability and drying effect of the pharmaceutical material, a protrusion 11 is provided on the rear side of the inner end of the limiting support frame 8. These protrusions 11 are designed as a whole with the limiting support frame 8 and are symmetrically distributed. Two opposite oblique protrusions 12 are provided on the protrusion 11 and the movable placement plate 10. A return spring 13 is installed between the two oblique protrusions 12 and fixed by welding. When the sealing door 2 is closed, the extrusion sheet 14 will move to the upper end of the movable placement plate 10 as the door moves, and the movable placement plate 10 will be squeezed and flattened by its arc design and smooth surface, ensuring that the pharmaceutical material is evenly heated during the drying process.
[0027] In addition, the edge of the movable placement plate 10 is designed in a semicircular shape, which is not only beautiful, but also can effectively prevent the material from scattering during the drying process. The outer end of the extrusion sheet 14 is also designed in an arc shape to ensure its uniformity when in contact with the movable placement plate 10. When the extrusion sheet 14 is opened with the sealing door 2, the return spring 13 will rebound using its characteristics, pushing the movable placement plate 10 to tilt, thereby quickly discharging the pharmaceutical material. This discharge method not only improves the discharge efficiency, but also requires a material storage device to be set at the lower end of the opening of the vacuum drying chamber 3 to collect the discharged pharmaceutical materials for subsequent processing and use.
[0028] The unique design and structure of this vacuum pharmaceutical drying oven provide an efficient, stable and uniform environment for the drying of pharmaceutical materials, ensuring the smooth progress of the pharmaceutical process and the steady improvement of product quality.
[0029] Working process: The operator places the pharmaceutical material to be dried on the movable placement plate 10. Since the edge of the movable placement plate 10 is designed in a semicircular shape, the material is effectively prevented from scattering during the drying process; the operator closes the sealing door 2 and ensures that the sealing door 2 is tightly closed through the locking device 4, thereby maintaining the vacuum environment inside the drying box; the operator sets the drying parameters, such as temperature, time, etc., through the control panel 6; the instrument 5 monitors the temperature, humidity and other parameters in the drying box in real time to ensure that the drying process is stable; the vacuum drying chamber 3 starts working, and provides stable support for the pharmaceutical material through its internal multiple limit frames 7 and limit support frames 8, ensuring the stability and uniformity of the material during the drying process; the movable placement plate 10 is connected to the limit support frame 8 through the hinge assembly 9 and is set up in the frame. The design of the reset spring 13 and the oblique boss 12 enables the movable placement plate 10 to be squeezed and laid flat when the sealing door 2 is closed, ensuring that the material is evenly heated;
[0030] When the drying process is completed, the operator opens the sealed door 2; as the sealed door 2 is opened, the extrusion sheet 14 moves, and the return spring 13 rebounds by its characteristics, pushing the movable placement plate 10 to tilt; the pharmaceutical material is quickly discharged due to the tilt of the movable placement plate 10, and falls into the material storage device arranged at the lower end of the opening of the vacuum drying chamber 3; the operator collects the pharmaceutical material in the material storage device for subsequent packaging, storage or further processing; the operator cleans the inside of the drying box and prepares for the next drying operation; during the entire working process, the efficient, stable and uniform environment of the vacuum pharmaceutical drying box ensures high-quality drying treatment of the pharmaceutical material, thereby ensuring the smooth progress of the pharmaceutical process and the steady improvement of product quality.
