DETAILED DESCRIPTION

[0024] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0025] See also Figure 1-4 A spray drying system for preparing Chinese herbal medicine slices comprises an atomizing mechanism 1, wherein the atomizing mechanism 1 comprises an atomizing drying cylinder 101, and a top cover 102 is detachably connected to the top of the atomizing drying cylinder 101. The top cover 102 is provided to lower the top cover of the atomizing drying cylinder 101. A plurality of connecting bolts 103 are threadedly connected in an annular array around the top cover 102, and each group of connecting bolts 103 is threadedly connected to the atomizing drying cylinder 101. The top cover 102 is connected and fixed to the atomizing drying cylinder 101 by the connecting bolts 103, so that the top cover 102 can be easily disassembled, and the entire spray drying system can be easily inspected and maintained.

[0026] A medicine liquid atomizer 105 is fixedly connected to the top of the top cover 102, an input end of the medicine liquid atomizer 105 is fixedly connected to an input pipe 104, an output end of the medicine liquid atomizer 105 is fixedly connected to an atomizing nozzle 106, and the atomizing nozzle 106 is located inside the atomizing drying cylinder 101. The setting of the medicine liquid atomizer 105 can atomize the Chinese medicine liquid input by the input pipe 104 when starting the work, and finally spray it into the inside of the atomizing drying cylinder 101 through the atomizing nozzle 106.

[0027] The drying mechanism 2 includes an annular tube 204 uniformly sleeved on the outside of the atomizing drying cylinder 101, and a plurality of guide tubes 205 are fixedly connected to the interior of each group of annular tubes 204 in an annular array, and the guide tubes 205 are connected to the annular tubes 204. Each group of guide tubes 205 penetrates the atomizing drying cylinder 101 and is connected to the atomizing drying cylinder 101. When the annular tube 204 discharges hot air, it can be discharged into the interior of the atomizing drying cylinder 101 through the guidance of each group of guide tubes 205, so that the hot air can evaporate the atomized medicine liquid after contacting with the atomized medicine liquid, thereby forming medicine particles.

[0028] An isolation tube 208 is fixedly connected to the outside of the atomizing drying cylinder 101, and each group of annular tubes 204 passes through the isolation tube 208. The setting of the isolation tube 208 can play a role in isolating and heat-insulating the annular tube 204, and reduce the probability of heat loss of the hot air flow inside the annular tube 204. The bottom of the isolation tube 208 is fixedly connected to a plurality of columns 210 in an annular array, and the setting of the columns 210 can play a supporting role for the isolation tube 208 and the atomizing drying cylinder 101. A plurality of reinforcing ribs 209 are fixedly connected to the outside of the atomizing drying cylinder 101 in an annular array, and each group of reinforcing ribs 209 is fixedly connected to the isolation tube 208. The setting of the reinforcing ribs 209 can further connect and fix the isolation tube 208 to the atomizing drying cylinder 101, thereby improving the connection stability between the isolation tube 208 and the atomizing drying cylinder 101.

[0029] The lower side of the inner wall of the atomizing and drying cylinder 101 is fixedly connected with a bottom ring 201, and the top of the bottom ring 201 is fixedly connected with an inner cylinder 202, and the setting of the bottom ring 201 can provide support for the inner cylinder 202. The top of the inner cylinder 202 is abutted with a sealing ring 207, and the sealing ring 207 is fixedly connected to the top cover 102. The setting of the sealing ring 207 can seal the gap between the inner cylinder 202 and the top cover 102. The surrounding side of the inner cylinder 202 is evenly provided with a plurality of jet holes 203, and the setting of the jet holes 203 can divert the hot air flow discharged from the guide tube 205, so that the hot air flow can be evenly discharged into the interior of the atomizing and drying cylinder 101, and at the same time, the probability of the atomized liquid medicine contacting the inner wall of the atomizing and drying cylinder 101 and the inner cylinder 202 can be prevented, thereby reducing the probability of the medicine bonding inside the inner cylinder 202 and the atomizing and drying cylinder 101. Each group of air jet holes 203 is inclined toward the middle of the atomizing drying cylinder 101 , so that the hot air flow discharged from the air jet holes 203 can blow the formed liquid medicine and medicine downward, thereby reducing the probability of the liquid medicine contacting the top cover 102 .

[0030] Isolation rings 206 are provided above each layer of flow guide tubes 205, and each group of isolation rings 206 is fixedly connected to the atomizing drying cylinder 101 and the inner cylinder 202. The setting of the isolation rings 206 can separate the area between the atomizing drying cylinder 101 and the inner cylinder 202, so that each layer of annular tubes 204 can discharge hot air flows with gradually decreasing temperatures from top to bottom, so that the upper jet holes 203 can discharge hot air flows with higher temperatures, so that most of the atomized medicine liquid can be heated and evaporated, while the lower jet holes 203 can discharge hot air flows with lower temperatures, thereby reducing the probability of the formed medicine particles being heated and burnt.

[0031] In this embodiment, the liquid medicine atomizer 105 is a prior art and will not be described in detail here.

[0032] When in use, an airflow with gradually decreasing temperature is discharged from top to bottom into each group of annular tubes 204, so that the hot air flow is discharged into the space between the inner cylinder 202 and the atomizing drying cylinder 101 through each group of flow guide tubes 205, and finally discharged through each group of jet holes 203, and then the Chinese medicine liquid is input into the input pipe 104, and then atomized by the liquid medicine atomizer 105, sprayed into the inner cylinder 202 from the atomizing nozzle 106, and then contacted with the hot air flow discharged from the jet holes 203, so that the liquid medicine is evaporated to form Chinese medicine particles. The finally formed Chinese medicine particles fall from the bottom of the atomizing drying cylinder 101 under the action of gravity. Since the hot air flow is discharged through the groups of jet holes 203 on the side of the inner cylinder 202, the contact between the atomized liquid medicine and the inner cylinder 202 is reduced, causing the probability of adhesion to the inner wall of the inner cylinder 202 after drying.

[0033] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
