Description

Technical Field

[0001] The utility model relates to the technical field of millet bran production, in particular to a millet bran impurity removing device. Background Art

[0002] Millet bran is a byproduct of the millet processing process, accounting for 5% to 7% of the millet mass. According to the annual millet production of 4.5 million tons in my country, about 300,000 tons of millet bran are produced each year. The millet bran contains 16% to 18% oil and 16% to 20% protein. Millet bran oil is rich in unsaturated fatty acids, vitamin E, oryzanol, phytosterols and other bioactive ingredients.

[0003] Millet bran oil can also be used in traditional Chinese medicine (TCM theory uses it to treat psoriasis, neurodermatitis, chronic eczema, psoriasis, ulcers and other diseases, which are all recorded in Compendium of Materia Medica) and cosmetics production. It can be seen that millet bran oil is a special vegetable oil with high nutritional value and high added value, and has broad development and utilization value. Making full use of millet bran resources and extracting edible vegetable oil from the by-product of millet processing as raw material is also a beneficial supplement to my country's edible oil resources.

[0004] The millet bran remaining after millet processing is not handled too finely during storage and transportation, which will cause sand and stones to remain in the millet bran. The sand and stones remaining in the subsequent processing will affect the quality of the product after millet bran processing, and the stones in the millet bran will affect the service life of the subsequent processing equipment, causing damage to the processing equipment, which is very troublesome.
