Description

Technical Field

[0001] The utility model belongs to the field of corn starch rough processing, in particular to a device for removing impurities from corn starch rough processing raw materials. Background Art

[0002] Cornstarch is a starch product made from processed corn. It's a common food ingredient, widely used in the food, pharmaceutical, and cosmetic industries. In the food industry, cornstarch is often used as a thickener, gelling agent, and stabilizer. It can be used to make foods like flour, noodles, pastries, and meat products, enhancing their texture and taste. Cornstarch is also used in various processed foods, including candies, biscuits, and frozen foods. Cornstarch also has other applications. For example, in the pharmaceutical industry, cornstarch is often used as an auxiliary material in the preparation of tablets; in the cosmetics industry, cornstarch is used in foundations and skincare products. In short, cornstarch is a versatile food ingredient with widespread applications in the food, pharmaceutical, and cosmetic industries. It plays a vital role in food manufacturing and other fields.

[0003] Comparatively, the Chinese patent application number CN202320850516.X discloses a device for removing impurities from raw materials for coarse processing of corn starch, comprising an impurity removal mechanism, a driven wheel mounted on the outer end of the impurity removal mechanism, the driven wheel being connected to a drive motor via a transmission belt located on the outer side of the impurity removal mechanism, one end of the driven wheel being located inside the impurity removal mechanism and having a rotating shaft mounted thereon, a nylon brush being mounted in an annular array on the outer side of the rotating shaft, a raw material basket being provided below the rotating shaft and located inside the impurity removal mechanism, the lower surface of the raw material basket being mounted with an inclined baffle having through-holes formed in an array on the upper surface of the inclined baffle, and a movable cover being connected to one side of the raw material basket via a rotating shaft. The driven wheel is driven by a drive motor to control the two rotating shafts, which drive the nylon brushes to rotate in opposite directions. The corn silk in the raw material is intercepted by the squeezing action of the nylon brushes on the outer sides of the two rotating shafts, and the corn kernels fall into the raw material basket, facilitating the removal of impurities.

[0004] The disadvantages of the above patent are: corn silk is removed by rotating a nylon brush, and during the operation, corn silk easily adheres to the nylon brush in large quantities, affecting the removal effect. At the same time, the nylon brush needs to be cleaned after the processing is completed, which requires a lot of time and cost. Utility Model Content

[0011] Furthermore: the bracket and the housing device are welded together, and the cam is connected to the motor flat key.

[0012] Furthermore: the fan is connected to the support frame by bolts.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The support frame supports the fan to rotate, forming an airflow that passes through the ventilation net. When the corn kernels slide through the ventilation net, the airflow carries away the lighter corn silk and dust, thus achieving the primary separation of the corn raw materials. The blown away corn silk and dust move along the air outlet pipe and are discharged from the inside of the device. The raw materials are cleaned by the fan blowing, which makes it easy to collect and clean the corn silk that is easily attached to the inside of the device, preventing its excessive accumulation from affecting the cleaning effect, and improving the processing cleanliness;

[0015] 2. The bracket supports the motor to drive the cam to rotate. The cam intermittently moves the roller upward, driving the screen plate to vibrate repeatedly up and down around the support, so that the corn kernels on the screen are further separated from the stones. At the same time, the corn kernels on the screen slide down along the screen plate and are finally discharged from the front of the base, completing the overall impurity removal work. The design of the cam driving the screen to vibrate improves the raw material separation effect, prevents the corn kernels from getting stuck on the screen, and further improves the smoothness of impurity removal.
