Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, in particular to a capsule drying device for capsule production. Background Technique

[0002] Drying treatment is one of the important processes in the capsule production process. The capsule production drying device is mainly used to remove the moisture in the capsules during the production of drugs or nutritional supplements to ensure the stability and effectiveness of the capsules. The design and functions of this device usually include aspects such as drying principle, temperature control system, humidity control, air flow design, cleaning and maintenance, production capacity, etc.

[0003] Using a drying device to dry capsules can prevent moisture from affecting their stability, protect the drug ingredients, ensure proper drug release and extend the product shelf life, but there are still some problems: 1) When the traditional flipping drying equipment dries capsules, there will be a phenomenon of capsule accumulation, which affects the drying efficiency; 2) The contact area between hot air and capsules is small; Therefore, in view of the above current situation, there is an urgent need to develop a capsule drying device for capsule production to overcome the deficiencies in current practical applications and meet the current needs. Content of the Utility Model

[0004] The purpose of the utility model is to provide a capsule drying device for capsule production to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A capsule drying device for capsule production, including a tank body, a conical tank bottom and a base. The conical tank bottom is vertically installed at the bottom end of the tank body, the base is vertically installed at the bottom of the tank body, a motor is installed at the bottom of the conical tank bottom, a top cover is installed at the top end of the tank body, and a three-dimensional drying component is embedded in the tank body;

[0006] The three-dimensional drying component includes an inner cylinder, a screw conveyor and an inner spiral feeding net. The inner cylinder is vertically arranged at the middle position inside the tank body, and the bottom end of the inner cylinder is detachably connected to the inner bottom of the conical tank bottom. The screw conveyor is arranged inside the inner cylinder and is rotationally connected to the inner cylinder. The inner spiral feeding net is arranged around the outer wall of the inner cylinder. The screw conveyor is driven and connected to the motor. Specifically, the motor drives the screw conveyor to rotate, and cooperates with the inner cylinder to lift the capsules.

[0007] Preferably, the tank body is composed of a composite of an inner tank body and an outer tank body. A plurality of groups of oppositely arranged circulation fans are arranged through the side wall of the inner tank body. Electric heating elements are embedded in the side wall of the outer tank body. Specifically, a heating space and a heat circulation channel are formed between the inner tank body and the outer tank body. The hot air is introduced into the inner part of the inner tank body through one side of the circulation fan, and then the air inside the inner tank body is exported to the space between the inner tank body and the outer tank body through the other side of the circulation fan for heating treatment.

[0008] Preferably, the inclination angle of the inner spiral feeding net is 60 degrees. Specifically, its relatively large inclination angle can ensure the smooth sliding of the capsules and avoid blockage.

[0009] Preferably, a through hole for feeding is provided at the bottom end of the inner cylinder. Specifically, the capsules enter the inner cylinder through the through hole and are lifted by the auger to realize the cyclic drying process.

[0010] Preferably, a number of ventilation holes are provided in the inner spiral feeding net.

At the same time, the relatively large inclination angle of the inner spiral feeding net ensures the smooth rolling of the capsules.

[0011] Compared with the prior art, the present utility model provides a capsule drying device for capsule production, which has the following beneficial effects:

[0012] It uses a three-dimensional drying component as the drying path, allowing the capsules to be lifted by the auger and then naturally roll down along the inner spiral feeding net. This method can prevent the large-scale accumulation of capsules from affecting the drying efficiency, and at the same time increase the contact area between the capsules and hot air, further improving the drying efficiency. The hot air forms a horizontal convection cycle, and the good heat circulation path can effectively ensure the balance of the capsule drying efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Embodiment:

[0021] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a capsule drying device for capsule production, including a tank body 10, a conical tank bottom 20 and a base 40. The conical tank bottom 20 is vertically installed at the bottom end of the tank body 10, the base 40 is vertically installed at the bottom of the tank body 10, a motor 30 is installed at the bottom of the conical tank bottom 20, a top cover 50 is installed at the top end of the tank body 10, and a three-dimensional drying component 60 is embedded and installed inside the tank body 10;

[0022] The three-dimensional drying component 60 includes an inner cylinder 601, an auger 602 and an inner spiral feeding net 603. The inner cylinder 601 is vertically arranged at the middle position inside the tank body 10, and the bottom end of the inner cylinder 601 is detachably connected to the inner bottom of the conical tank bottom 20. The auger 602 is arranged inside the inner cylinder 601 and is rotationally connected to the inner cylinder 601. The inner spiral feeding net 603 is arranged around the outer wall of the inner cylinder 601. The auger 602 is drivingly connected to the motor 30. Specifically, the motor 30 drives the auger 602 to rotate, and cooperates with the inner cylinder 601 to lift the capsules.

[0023] Preferably, the tank body 10 is composed of an inner tank body 101 and an outer tank body 102. A plurality of groups of oppositely arranged circulation fans 103 are arranged through the side wall of the inner tank body 101, and an electric heating element 104 is embedded and installed on the side wall of the outer tank body 102. Specifically, a heating space and a heat circulation channel are formed between the inner tank body 101 and the outer tank body 102. The hot air is introduced into the inner part of the inner tank body 101 through one side of the circulation fan 103, and then the air inside the inner tank body 101 is exported to the space between the inner tank body 101 and the outer tank body 102 through the other side of the circulation fan 103 for heating treatment.

[0024] Preferably, the inclination angle of the inner spiral feeding mesh 603 is 60 degrees. Specifically, its relatively large inclination angle can ensure the smooth sliding of the capsules and prevent blockage.

[0025] Preferably, a through hole for feeding is provided at the bottom end of the inner cylinder 601. Specifically, the capsules enter the inner cylinder 601 through the through hole and are lifted by the auger 602 to realize the cyclic drying process.

[0026] Preferably, a number of ventilation holes 6031 are provided on the inner spiral feeding mesh 603. Specifically, the hot air can circulate in the tank body 1 through the provided ventilation holes 6031, preventing the inner spiral feeding mesh 603 from blocking the upward movement of the hot air. At the same time, the inclination angle of the inner spiral feeding mesh 603 is relatively large, ensuring the smooth rolling of the capsules.

[0027] Working principle: The capsules are introduced into the tank body 10, the motor 30 is started to drive the auger 602 to operate. The capsules enter through the through hole at the bottom end of the inner cylinder 601 and continuously rise under the cooperation of the auger 602 and the inner cylinder 601. Finally, they fall from the top end of the inner cylinder 601 into the top end of the inner spiral feeding mesh 603 and freely roll down along the inner spiral feeding mesh 603. Repeating the above process realizes the cyclic rolling of the capsules. At the same time, the electric heating element 104 heats the internal air, and the hot air is introduced into the inner tank body 101 by the circulating fan 103 on one side to dry the internal capsules. Then, the internal air of the inner tank body 101 is discharged by the circulating fan 103 on the other side and returns to the electric heating element 104 along the inner tank body 101 and the outer tank body 102. After secondary heating, it enters the hot air circulation process again. It should be noted that multiple groups of circulating fans 103 are respectively aligned with different heights of the inner spiral feeding mesh 603, which can ensure the uniform drying of the capsules.

[0028] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the said element.
