Description

Technical Field

[0001] The utility model relates to the technical field of spray dryers, in particular to a plant extraction spray dryer. Background Art

[0002] Centrifugal spray dryer is suitable for the production of trace particle powder in laboratories of research institutes and food, pharmaceutical and chemical enterprises. It is widely applicable to all solutions such as emulsions and suspensions, and is suitable for drying heat-sensitive materials such as biological products, biological pesticides, enzyme preparations, etc. Because the sprayed materials are only exposed to high temperatures when they are sprayed into mist and are heated instantly, these active materials still maintain their active ingredients unchanged after drying.

[0003] In the prior art, the centrifugal spray dryer forms particles through atomization and drying, and then is recycled through a dust collector with a recycling pipeline. However, due to the high temperature of the particles, more particles accumulate in the narrow recycling pipeline, and the particles are easily adhered to each other, resulting in large-sized particles, which need to be filtered and crushed later. In the existing centrifugal spray dryer, particles are formed in the drying chamber, and the particles will adhere to the inner wall of the chamber, or some particles cannot be recycled in time due to the diameter of the dust collector or the long installation distance.

[0004] Therefore, a plant extraction spray dryer is needed to be improved in view of the above problems. Utility Model Content

The scraper in the cleaning mechanism can scrape off particles inside or at the edge of the drying bin body in real time, allowing the particles to fall into the return connecting pipe to prevent the particles from being unable to be recovered.

[0008] Preferably, a plurality of latch teeth are evenly arranged on the outer surface of the rotating ring, and a gear is movably provided on one side of the upper end of the drying bin through a rotating shaft, and the gear and the latch teeth are meshed with each other. The rotating ring can be driven to rotate by rotating the gear in coordination with the latch teeth, thereby driving the scraper to rotate around the inner side wall of the drying bin, thereby cleaning the interior of the drying bin.

[0009] Preferably, a motor is fixedly provided on one side of the upper end of the drying bin via a mounting seat, and the output shaft end of the motor is transmission-connected to the rotating shaft where the gear is located, so that the gear can be driven to rotate by the motor, thereby driving the rotating ring to rotate.

[0011] Preferably, an air inlet pipe is fixedly provided on one side of the surface of the drying bin, and hot air can be conveniently introduced into the drying bin through the air inlet pipe.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model can make the material enter the discharge pipe at the lower end through the cyclone dust collector and the centrifugal force. At this time, the material can be pushed to move in the discharge pipe through the rotation of the spiral transmission rod, which can avoid the particles from piling up in one place when discharging. The rotation of the spiral transmission rod can also be used to stir the particles in real time to prevent them from sticking.

[0014] 2. The utility model can drive the gear to rotate by electric power, and when the gear rotates, the rotating ring can be driven to rotate by the engaging teeth, thereby driving the scraper to rotate around the inner side wall of the drying bin, so that the inside of the drying bin can be cleaned. In this way, the scraper can scrape off the particles inside or at the edge of the drying bin in real time, allowing the particles to fall into the return connection pipe to prevent the particles from being unable to be recovered.
