TECHNICAL FIELD

[0001] The utility model relates to rice powder processing technical field especially, relates to a rice powder processing rice impurity removing device. BACKGROUND

[0002] Rice powder is a strip-shaped, silk-shaped rice product made of rice as raw material through soaking, cooking and pressing processes, but not the powdered material made of rice as raw material through grinding in the word sense. In the process of rice powder processing, the rice impurity removing device is a pretreatment equipment, which aims to remove impurities in the raw material rice to ensure the quality of rice powder.

[0003] Impurities such as mud, metal fragments, straw and insect eggs may be mixed in rice, which will contaminate the finished product and even cause food safety problems if directly processed. The impurities will affect the taste, color and uniformity of rice powder.

However, in the prior art, the screen holes on the screen are relatively single, and during the screening process of impurities in rice, the rice husk or particulate matter dust is relatively light in volume, which cannot be effectively and completely screened out, resulting in a small amount of impurities still existing in the screened rice, which affects the screening accuracy of rice. In addition, during the impurity removing process, the screen may be blocked due to long-term use, which affects the falling speed of rice during the subsequent screening process. Therefore, there is an urgent need for a rice powder processing rice impurity removing device to solve the above problems. UTILITY MODEL CONTENTS
