Embodiment 1

[0022] Using walnut meal as raw material, it is processed by the following wet ultrafine pulverization method:

[0023] 1. The walnut meal is crushed mechanically to obtain coarse walnut meal powder;

[0024] 2, coarse walnut meal powder is mixed with water, and the ratio of coarse walnut meal powder and water is 1: (8-14) in kg / L, obtains the walnut slurry that particle size is bigger, stand-by;

[0025] 3. Pour the treated walnut slurry with larger particle size into the SX-30 agitating ball mill produced by Wuxi Xinguang Powder Processing Technology Co., Ltd. to carry out wet ultrafine pulverization. In kg / L, the ball-to-material ratio is ( 1-6): 10, the medium is Φ10mm zirconia balls, the refining time is 30-120min, the particles are d 50 6-17μm.

[0026] The above process adopts the ball mill, utilizes the wet method, and adopts ultrafine pulverization technical means to form the technical scheme of the present invention. The raw material of walnut meal has the charact...

Embodiment 2

[0028] 1. The walnut meal is crushed mechanically to obtain coarse walnut meal powder;

[0029] 2. Coarse walnut meal powder is mixed with water in a ratio of 1:9 in kg / L to obtain a walnut slurry with a larger particle size for use;

[0030] 3. Pour the processed walnut slurry with large particle size into a stirring ball mill for wet superfine grinding. The ball-to-material ratio is 3:10 in kg / L, the medium is Φ10mm zirconia balls, and the refining time is 90 minutes. , particle d 50 is 7 μm.

Embodiment 3

[0032] 1. The walnut meal is crushed mechanically to obtain coarse walnut meal powder;

[0033] 2. Coarse walnut meal powder is mixed with water in a ratio (W / V, kg / L) of 1:8 to obtain a larger walnut slurry for later use;

[0034] 3. Pour the processed walnut slurry with larger particle size into a stirring ball mill for wet ultrafine pulverization. The ball-to-material ratio (W / V, kg / L) is 1:10, and the medium is Φ10mm zirconia balls. Slurry time 30min, particle d 50 is 6 μm.

Abstract

The invention discloses superfine grinding technology of walnut dregs by a wet process, belonging to the technical field of agricultural products and food processing. The method comprises the process flows of coarse grinding of walnut dregs, mixture of coarsely ground powder of walnut dregs and water and superfine grinding by the wet process by a ball mill, etc. The temperature is not raised in the process of grinding; therefore, the nutrient components of the walnut dregs can not be damaged. In terms of kg/L, the ratio of coarse powder of walnut dregs to water is 1:(8-14). The parameters of the superfine grinding technology by the wet process by the ball mill are as follows: the ball-to-powder weight ratio is (1-6):10, the media are phi10mm zirconia balls, the milk grinding time is 30-120min and d50 of the walnut milk granule is 6-17mu m. The superfine grinding technology lays the foundation for subsequent preparation of walnut powder through spray drying and the application range of the superfine grinding technology in the food industry is broadened.

Description

field of invention [0001] The invention relates to the technical field of agricultural products and food processing and preparation. Specifically, the present invention relates to the technical field of wet ultrafine grinding of walnut meal. Background technique [0002] The application of ultra-fine pulverization technology in food is a new attempt in the food processing industry, an improvement to the traditional craft formula, and a huge driving force for the development of new products. The application of ultrafine pulverization technology in food processing can improve the taste of food on the one hand. Since the ultrafine powder is as small as nanometers, the particles have surface effects, volume effects, quantum effects and macroscopic tunnel effects, etc. Larger adsorption, which is conducive to the digestion and absorption of substances; on the other hand, the ultrafine powder has good absorption and dispersibility, which can improve the activity and bioavailabili...
