Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spray dryers, in particular to a shaking component of a spray dryer. Background Art
[0002] Oat beta-glucan dry powder is a white to light yellow powder extracted from oat bran through processes such as hydrolysis, extraction, precipitation, drying, and sterilization. Spray dryer is a common equipment for the production of oat beta-glucan dry powder. The working principle of the spray dryer is that the liquid is sprayed into extremely fine mist droplets through an atomizer (such as a high-speed centrifugal atomizer). These mist droplets are in contact with hot air in parallel, evaporating water in a very short time and drying into finished products. The finished products are continuously output from the bottom of the drying tower and the cyclone separator, and the exhaust gas is discharged by the induced draft fan.
[0003] In the process of using a spray dryer to produce oat β-glucan dry powder, the mist liquid beads are dried into finished products and then output from the bottom of the drying tower and the cyclone separator. However, during the drying process, the materials are prone to agglomeration or accumulation with each other, resulting in uneven size of the finished products after output, affecting the quality of the finished products. In view of this, we propose a shaking component for a spray dryer. Utility Model Content

[0028] In this embodiment, the first telescopic tube 21 and the second telescopic tube 33 are both telescopic, and the first telescopic tube 21 and the second telescopic tube 33 are both made of rubber material. The telescopic property meets the vibration requirements of the screening box 2, and the rubber material has the advantage of wear resistance, which ensures the service life of the first telescopic tube 21 and the second telescopic tube 33.
[0029] In this embodiment, the discharge pipe 31 is fixedly connected to the scattering box 3 through a flange, and the discharge pipe 31 is inclined. The inclined design is conducive to discharging materials through the discharge pipe 31.
[0030] In this embodiment, fixing rods 10 are provided at four corners between the two fixing plates 1, and the fixing rods 10 are fixedly connected to the fixing plates 1 by bolts. The setting of the fixing rods 10 plays a role in stably supporting and fixing the fixing plates 1.
[0031] In this embodiment, the scatter box 3 is fixedly connected to the fixing plate 1 by bolts, and the scatter box 3 is a stainless steel product. The bolt fixing method ensures the installation reliability of the scatter box 3, and the stainless steel material has the advantage of corrosion resistance, which ensures the service life of the scatter box 3.
[0032] In this embodiment, the screening box 2 is made of stainless steel, and the rear side of the inner bottom of the screening box 2 is high around and low in the middle. This design is conducive to the finished products falling on the screen 23 to gather at the discharge bin 24 for discharge.
[0033] In this embodiment, the connecting pipe 25 passes through the fixing plate 1 located above, and the connecting pipe 25 is slidably connected to the fixing plate 1.

When the oat β-glucan dry powder product enters the screening box 2 through the feed hopper 20, the oat β-glucan dry powder product falls on the screen. On the net 23, as the screen 23 vibrates, the qualified oat β-glucan dry powder product falls and falls into the discharge pipe 31 through the discharge bin 24 and the connecting pipe 25, while the agglomerated oat β-glucan dry powder product moves along the screen 23 and enters the breaking box 3 through the first telescopic tube 21. At the same time, the rotating stirring rod 36 breaks up the agglomerated oat β-glucan dry powder product, and the broken oat β-glucan dry powder product enters the discharge pipe 31 and is discharged.
