Description

Technical Field

[0001] This utility model relates to the field of solid granulation production technology, and more specifically, to a solid dosage form granule drying line with sorting function. Background Technology

[0002] A solid dosage form granule drying line is an integrated, continuous production system that combines wet granulation, fluidized bed drying, granulation, and material conveying. It is primarily used for the pre-production stages of solid dosage forms such as tablets and capsules, as well as the production of granules. Its core equipment includes a wet granulator, fluidized bed dryer, granulator, and hopper elevator. Through fully automated, sealed feeding and piping connections, it achieves dust-free, high-efficiency, closed-loop production, meeting GMP requirements. This production line optimizes process parameters to ensure granule uniformity and quality stability while reducing energy consumption and pollution risks. In the current production process of solid dosage form granules, due to the long production line process, the dried granules contain floating dust, and the broken fine particles need to be sorted and filtered. However, the current production line does not have the ability to directly sort the particles, so the dried particles need to be sorted again after discharge. This results in a long production line, increased costs, and the particles cannot be kept sealed during the sorting and transfer process, which may cause contamination. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a solid dosage form drying line with sorting function to solve the problems in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution; A solid dosage form drying line with sorting function includes a vacuum feeder, a wet mixing granulator, a feed pump, a fluidized bed dryer, and a vibrating plug, characterized in that: the vacuum feeder is used to feed the wet mixing granulator, and the feed pump inputs the wet particles into the fluidized bed dryer for drying; A hydraulic cylinder is fixedly installed on the top of the fluidized bed dryer. The bottom end of the hydraulic cylinder penetrates and extends into the interior of the fluidized bed dryer and is fixedly installed with an arc-shaped cover. The outer side of the arc-shaped cover is slidably connected to the interior of the fluidized bed dryer. An elastic tube is fixedly connected to the top of the arc-shaped cover. The other end of the elastic tube penetrates and is fixedly connected to the outside of the fluidized bed dryer and is connected to the feed port of the vibrating plug through a pipe.

[0005] As a further description of the above technical solution: the bottom air inlet of the fluidized bed dryer is connected to a high-power hot air blower with adjustable power via a pipe.

[0006] As a further description of the above technical solution: a bracket is fixedly installed on the top of the rotary vibrating plug, a separation chamber is installed on the bracket, and an exhaust fan is installed on the top of the separation chamber.

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] To address the issue that current production lines lack direct sorting capabilities and require further sorting of dried granules after discharge, resulting in longer production lines and increased costs, Example 1 is proposed: Please see Figures 1-4In this embodiment, a solid dosage form drying line with sorting function includes a vacuum feeder 1, a wet mixing granulator 2, a feed pump 3, a fluidized bed dryer 4, and a vibrating plug 5. The vacuum feeder 1 is used to feed the wet mixing granulator 2, and the feed pump 3 inputs the wet granules into the fluidized bed dryer 4 for drying. A hydraulic cylinder 41 is fixedly installed on the top of the fluidized bed dryer 4. The bottom end of the hydraulic cylinder 41 penetrates and extends into the interior of the fluidized bed dryer 4 and is fixedly installed with an arc-shaped cover 42. The outer side of the arc-shaped cover 42 is slidably connected to the interior of the fluidized bed dryer 4. An elastic tube 43 is fixedly connected to the top of the arc-shaped cover 42, and the other end of the elastic tube 43 penetrates and is fixedly connected to the outside of the fluidized bed dryer 4 and communicates with the feed port of the vibrating plug 5 through a pipe.

[0015] The bottom air inlet of the boiling dryer 4 is connected to a high-power hot air blower 6 with adjustable power via a pipe. An exhaust pipe 10 is fixedly connected to the boiling dryer 4. A solenoid valve 11 is installed on the exhaust pipe 10. The exhaust pipe 10 is connected to an external industrial air purification device.

[0016] In this embodiment, raw material powder is injected into the wet mixing granulator 2 via a vacuum feeder 1 for granulation. Then, the wet particles are fed into the fluidized bed dryer 4 using a feed pump 3, and a high-power hot air blower 6 is turned on for drying. During the drying process, the solenoid valve 11 on the exhaust pipe 10 is opened to allow the hot and humid exhaust gas inside to be discharged to the industrial air purification equipment for purification and discharge. After drying is completed, the hydraulic cylinder 41 is activated to drive the arc-shaped cover 42 to descend, and the solenoid valve 11 is closed. At this time, the internal pressure of the fluidized bed dryer 4 is increased, and the air pressure blows the dried particles inside through the elastic tube 43 into the interior of the rotary vibrating plug 5 for sorting and output. Thus, the device achieves integrated drying and sorting operation, which is efficient, stable, and reduces production line costs.

[0017] To address the issue of potential contamination due to the inability to maintain particle sealing during the sorting and transfer process, Example 2 is proposed: Please see Figure 2 , Figure 3 and Figure 4 The top of the vibrating plug 5 is fixedly mounted with a bracket 7, a separation chamber 8 is mounted on the bracket 7, and an exhaust fan 9 is mounted on the top of the separation chamber 8; the output end of the exhaust fan 9 is connected to an external industrial air purification device.

[0018] In this invention, by starting the exhaust fan 9 and utilizing the cavity inside the separation chamber 8, the powder mixed in the particles is extracted. The particles fall into the interior of the vibrating plug 5 under the action of gravity. The exhaust fan 9, together with the high-power fan 6, ensures that the particles are smoothly output from the inside of the boiling dryer 4. Thus, the device has the advantages of simultaneous and closed drying and sorting, and closed processing of particles.

[0019] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
