[0002] Inositol is a white crystalline powder or white crystal, odorless, slightly sweet, and half as sweet as sucrose. Inositol is easily soluble in water and can be crystallized into colorless monoclinic crystals in water. At 100-110°C, inositol containing crystal water is easily dehydrated to become anhydrous crystals. At present, the production of inositol is mainly based on corn soaking water as raw material. my country is a major corn producer, so there is sufficient raw material for the production of inositol, which is not only conducive to increasing the added value of corn and reducing the waste of resources of grain and oil processing by-products, but also the inositol produced is used in medicine, food processing, feed, cosmetics and other fields, which is of great significance to people's health and life.

[0003] Inositol production requires a drying device. At present, in the inositol drying process, oven drying is often used, and after drying, a pulverizer is used to manually crush and load. This process not only has high energy consumption, but also is time-consuming and labor-intensive to manually load, which reduces the production capacity of inositol, and the dried material will produce a large amount of dust during the crushing process, polluting the operating environment. Therefore, how to reduce the energy consumption of inositol drying, reduce the labor intensity, reduce the dust in the drying process, and increase the production capacity of inositol is a problem that those skilled in the art need to solve. Utility Model Content

[0008] Preferably, the crystallization tank is connected to the centrifuge through a pipeline, a valve and a discharge pump.

[0009] Preferably, a flow meter is also provided on the pipeline connecting the crystallization tank and the centrifuge.

[0010] Preferably, the air outlets of each section of the vibrating fluidized bed dryer are connected to the second cyclone separator.

[0011] Preferably, the gas outlet of the second cyclone separator is connected to the bag dust collector and the second induced draft fan in sequence.

Moreover, the device is combined with the air flow crusher and the first cyclone separator, and the fine particles in the crushing process are sucked into the first cyclone separator under the action of the first induced draft fan, realizing the automation of the discharging process, making the discharging more stable, reducing the energy consumption of inositol drying, and increasing the production capacity.

[0026] The crystallizer 1 is connected to the centrifuge 2 through a pipeline, a valve and a discharge pump 6. A flow meter 7 is also provided on the pipeline connecting the crystallizer 1 and the centrifuge 2. The solid outlet of the centrifuge 2 is connected to the feed port 9 of the air flow mill 3. The crystal liquid in the crystallizer 1 enters the centrifuge 2 for centrifugation under the action of the discharge pump 6. The separated crystals have a small water content and directly enter the air flow mill 3 for pulverization.

[0027] The air flow pulverizer 3 is provided with a compressed air inlet 8, and the compressed air inlet 8 is located below the feed port 9; the discharge port at the top of the air flow pulverizer 3 is connected to the first cyclone separator 4, the solid outlet of the first cyclone separator 4 is connected to the vibrating fluidized bed dryer 5, and the first cyclone separator 4 is also connected to the first induced draft fan 10.

[0028] The material entering the air flow pulverizer 3 is blown up by the compressed air, and the rotating blown material collides with the material just entering the air flow pulverizer 3, and collides with the cylinder wall of the air flow pulverizer 3 for many times. Finally, under the action of the first induced draft fan 10, the fine particles are sucked into the first cyclone separator 4, and the collected fine particles are sent to the vibrating fluidized bed dryer 5 for rapid drying. Since the moisture content of the crystals after centrifugation is low and the crystals are more fragile than the materials after drying, the device first crushes the materials and then dries them, and the crushing and drying effects are better.

[0029] Further, in this embodiment, if Figure 1 As shown, the gas outlets of each section of the vibrating fluidized bed dryer 5 are connected to the second cyclone separator 11. The gas outlet of the second cyclone separator 11 is connected to the bag dust collector 12 and the second induced draft fan 13 in sequence; the solid outlet of the second cyclone separator 11 is connected to the vibrating fluidized bed dryer 5. The crushed material enters the vibrating fluidized bed dryer 5. Under the action of the vibration force, the material is thrown forward in the horizontal direction and moves continuously, and contacts and exchanges heat with the hot air in the vibrating fluidized bed dryer 5. The hot air after heat exchange in the vibrating fluidized bed dryer 5 enters the second cyclone separator 11, and the separated wet air enters the bag dust collector 12 for dust removal. After dust removal, it is discharged under the action of the second induced draft fan 13; the separated solid enters the vibrating fluidized bed dryer 5 and is discharged together with the dried material, thereby avoiding the loss of inositol.

[0030] Further, in this embodiment, if Figure 1 and Figure 2As shown in common, the bag of the bag dust collector 12 is connected to the back-blowing air bag 14, and the bag frame 16 of the bag dust collector 12 is provided with a trumpet-shaped air outlet 15, and the back-blowing air bag 14 is connected to the bag through the trumpet-shaped air outlet 15. In order to avoid the clogging of the bag in the bag dust collector 12, the device is provided with a back-blowing air bag 14 to regularly pass gas into the bag dust collector 12 for back-blowing cleaning; the provision of the trumpet-shaped air outlet 15 can effectively prevent interference from external airflow, and prevent the compressed air from spreading out quickly, thereby improving the back-blowing cleaning effect.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
