Description

Technical Field

[0001] This utility model relates to the field of steamed cake production technology, specifically a screening device for steamed cake production. Background Technology

[0002] Fermented cake is a traditional delicacy with a history of over 200 years. Its main ingredients are refined flour, maltose, milk powder, sweet wine, soda ash, baking soda, etc. It is made through a series of processes including dough preparation, fermentation of sweet wine, sugar pickling, cutting into pieces, shaping, and baking. The flour needs to be screened during the production process of fermented cake.

[0003] Chinese patent discloses a screening device for flour production (authorization announcement number CN209205763U). In use, flour enters the space between the partition plates through the feed inlet. A rotary motor drives a stirring rod to rotate, thus stirring the flour. Simultaneously, the blades on the rotating rod follow the stirring rod, which can disperse and separate impurities from the flour while stirring. The stirred flour falls onto the top of the filter screen, and a vibrating motor vibrates the filter screen, causing the fine flour to fall into the storage bin. A blower blows the filtered flour to the discharge pipe, and finally, the flour is further screened through the fine holes on the sieve plate. However, as is common sense, because flour has a low density and can form large clumps when it gets damp, it is easy for flour to cause blockage when it enters the feed inlet, thus affecting the subsequent screening process.

[0022] The servo motor 61 is model ACSM110-G04030LZ.

[0023] Working principle: When using this device, pour flour into the feed inlet 4. When the feed inlet 4 becomes blocked, pull the horizontal bar 51 to the left, then rotate the horizontal bar 51 90 degrees clockwise. This will move the unblocking rod 54 above the feed inlet 4. Then, move the horizontal bar 51 up and down. At this time, the sliding of the first adjusting rod 52 on the first connecting rod 55 and the sliding of the second adjusting rod 53 on the second connecting rod 56 allow the unblocking rod 54 to move up and down within the feed inlet 4, thus completing the unblocking work. The flour then enters the box 1 and falls onto the first screen 67. At this time, the servo motor is activated. The servo motor 61 rotates in both directions, which in turn drives the first support 63 and the second support 64 to rotate in both directions. The rotation of the first support 63 and the second support 64 in both directions drives the third support 65 and the fourth support 66 to move, thereby driving the first screen 67 and the second screen 68 to move up and down. At this time, after the flour passes through the shaking first screen 67, the qualified flour falls onto the second screen 68. After being shaken by the second screen 68, the qualified flour can be discharged through the discharge port. The user only needs to open the box door 2 to clean the unqualified products on the first screen 67 and the second screen 68.
