Description

Technical Field

[0001] The invention discloses a curdlan dryer, belonging to the technical field of powder drying. Background Art

[0002] After processing, curdlan needs to be further dried before it can be packaged. The dried curdlan can significantly improve its stability and shelf life. It can maintain its gelling properties when stored for a long time in a dry state. It can be stored for a long time in a dry state without losing its gelling properties. However, it is easy to absorb moisture in a humid environment, resulting in a decline in product quality or even deterioration.

[0003] After drying, curdlan is in powder form with good fluidity, which is easy to transport and use. Powdered curdlan occupies little space during packaging and storage, and is not easy to agglomerate under reasonable storage conditions, which can better meet the needs of industrial production.

[0004] Dried curdlan can be used as a thickener, stabilizer, etc. to improve the texture and taste of the product. In summary, drying is a key step in the production and application of curdlan. It can improve the stability and preservation of the product, facilitate transportation and use, remove moisture to increase purity, optimize the production process, and meet specific application requirements.

[0052] The first air amplifier compressed air inlet pipe 31 is in communication with the first air amplifier compressed air inlet 310 .

[0053] The material enters the first air amplifier 3 from the material inlet duct 2. Since the compressed air inlet pipe 31 of the first air amplifier is connected to the vortex tube hot air outlet 43, the air flow carries the material, and after being heated by the vortex tube hot air outlet 43 and the air flow amplification effect of the air amplifier, a high-speed and high-temperature air flow is formed. After the air flow enters the wind processing device 1, the air flow enters the wind processing device 1 tangentially, and the air flow carries the material to perform a circular motion. Due to the different centrifugal forces of powder and gas, the powder material will fall due to gravity and centrifugal force and fall into the collecting tank 11.

[0055] It is transported to the condensation component 8, and the top gas delivery channel 6 is connected with the condensation component 8 in a tangential direction.

The powder spraying circulation chamber 13 and the hot air collecting chamber 14 are communicated with each other.

[0058] The inner shell wall 131 of the powder spraying circulation chamber is divided into an elliptical spherical structure. An inward protrusion 133 is set at the top of the inner shell wall 131 of the powder spraying circulation chamber. The powder spraying circulation chamber 13 includes the inner shell wall 131 of the powder spraying circulation chamber, and the inner shell wall 131 of the powder spraying circulation chamber is an elliptical spherical shell.

[0059] The protrusion 133 extends into the powder spraying circulation chamber 13, and a number of circular exhaust gas leakage holes 134 are provided on the shell wall of the protrusion 133 near the hot air collecting chamber 14, and the exhaust gas leakage holes 134 are arranged around the outer peripheral surface of the protrusion 133; two powder spraying circulation chamber inner cavities 132 are provided in the inner shell wall 131 of the powder spraying circulation chamber, and the two powder spraying circulation chamber inner cavities 132 are separated by the protrusion 133.

[0060] An annular wind blade nozzle 136 is provided at the bottom of the powder spraying circulation chamber 13 , and a nozzle center protrusion 137 is provided at the center of the annular wind blade nozzle 136 . The annular wind blade nozzle 136 is fixed to the bottom of the powder spraying processing device 19 through an annular wind blade support seat 135 .

[0061] The conveying device 12 includes a cylindrical conveying device shell 102, a spiral conveying blade shaft 121 is arranged in the conveying device shell 102, the conveying device shell 102 is connected to a trumpet-shaped collecting bin 1101, and a screw conveyor drop-out port 1102 is arranged at the bottom of the trumpet-shaped collecting bin 1101, the spiral conveying blade shaft 121 extends out of the conveying device shell 102, and the part of the spiral conveying blade shaft 121 extending out of the conveying device shell 102 is located above the annular wind blade nozzle 136; a support leg 122 is arranged on the conveying device shell 102.

[0062] The trumpet-shaped aggregate bin 1101 is located in the aggregate tank 11 , and the diameter of the trumpet-shaped aggregate bin 1101 is equal to the diameter of the aggregate tank 11 .

[0063] After the powder material falls into the trumpet-shaped collecting bin 1101, it gradually accumulates. When it accumulates to a certain level, the conveying device 12 works to convey the material to the upper part of the annular wind blade nozzle 136. That is, the descending material is blown up again by the hot air at the annular wind blade nozzle 136, forming a continuous drying cycle.

[0064] The annular wind blade nozzle 136 includes an annular wind blade upper cover 1371 and an annular wind blade body 1372 . The annular wind blade upper cover 1371 and the annular wind blade body 1372 are detachably connected by bolts.

[0065] Two symmetrically arranged wind blade air inlet pipes 1364 are opened in the annular wind blade body 1372, and the two wind blade air inlet pipes 1364 take in air at the same time.

[0066] The wind blade air inlet pipe 1364 is connected to the wind blade air inlet pipe 1361.

[0067] A circular wind blade air delivery groove 1366 is provided on the annular wind blade body 1372. One side wall of the wind blade air delivery groove 1366 close to the center of the annular wind blade body 1372 forms an annular wind blade inner wall 1368, and the other side wall forms an annular wind blade air outlet wall 1369. The upper surfaces of the annular wind blade inner wall 1368 and the annular wind blade air outlet wall 1369 are not flush, and the height of the annular wind blade inner wall 1368 is slightly lower than the annular wind blade air outlet wall 1369.

[0068] The height of the annular wind blade inner wall 1368 is slightly lower than the height of the annular wind blade body 1372 , and the annular wind blade air outlet wall 1369 is flush with the upper surface of the annular wind blade body 1372 .

[0069] The annular wind blade body 1372 has a conical blanking cone slope 1365, and the large diameter end of the blanking cone slope 1365 faces upward.

[0070] Two wind blade air inlet pipes 1364 are provided on the annular wind blade body 1372 , and the wind blade air inlet pipes 1364 are connected to the wind blade air delivery slot 1366 .

[0071] After the annular wind blade upper cover 1371 and the annular wind blade body 1372 are connected, a gap is formed between the annular wind blade inner wall 1368 and the lower surface of the annular wind blade upper cover 1371 to form an annular wind blade air outlet 1367 .

Due to the wall attachment effect, the airflow will be guided by the wind blade conical head 1362 to form a rotation lift force.

[0074] The large diameter end of the wind blade conical head 1362 is located at the bottom, and the air flow forms an upward blowing force between the wind blade conical head 1362 and the annular wind blade outlet 1367.

[0075] The material is blown away by the wind again to form an airflow of mixed materials. During the rising process of the airflow, it is blocked by the protrusion 133 and split into two airflows. The two airflows rotate and rise in opposite directions along the outer wall of the protrusion 133. The airflow containing more material spirals down along the inner wall of the chamber due to gravity, forming a circulation with the rising airflow; the lighter airflow enters the hot air collecting chamber 14 through the exhaust gas leakage hole 134, and then encounters the rising airflow to form a powder spraying cycle.

[0076] Hot air is introduced into the bottom air inlet pipe 17, and the condensing air and drying air outlet pipe 15 are connected to the bottom air inlet pipe 17. A second air amplifier 16 is provided on the bottom air inlet pipe 17; the hot air is connected to the wind blade air inlet pipe 1361 after passing through the second air amplifier 16.

[0077] The present invention performs secondary drying of the material through the annular wind blade nozzle 136, with good drying effect. The use of the first air amplifier 3 and the second air amplifier 16 can save energy, especially the use of the cooling air generated by the vortex tube component 4 to cool and dry the airflow, and the use of hot air to heat the material, thereby improving energy utilization and reducing energy consumption.
