Description

Technical Field

[0001] The invention belongs to the field of walnut slurry, and particularly relates to a multi-stage refinement device for walnut slurry. Background Art

[0002] Walnuts have remarkable brain-boosting effects and rich nutritional value, and have been highly praised by more and more people. Walnuts have high medicinal value and are widely used in traditional Chinese medicine. Walnut milk is a plant protein beverage with walnuts as the main raw material. Walnut milk is a pure natural plant protein beverage. This product is made with modern technology and scientific blending and refinement. It has a delicate taste and a special walnut rich aroma. It can be drunk cold or hot. The hot drink has a stronger aroma. This product retains the original nutritional ingredients of walnut kernels. It is particularly worth mentioning that the phospholipids it contains have a good protective effect on brain nerves. Regular drinking has a good health care effect on arteriosclerosis, hypertension, coronary heart disease and anti-aging for the elderly. Therefore, this product is a superior beverage with health value.
