Embodiment 1

[0015] Wash the pea dregs with water to remove impurities and starch substances, add 8 times the amount of warm water at 30°C to the removed pea dregs to form a suspension, choose warm water to dilute the pea dregs and disperse them evenly in water, for subsequent homogeneity The high-speed centrifugal homogenization in the machine provides a guarantee to avoid the local high temperature caused by sudden temperature changes, or the dietary fiber agglomeration and suspension instability caused by the uneven temperature of the suspension and the large temperature difference, and then the suspension is mechanically pre-treated After the crushing treatment, enter the vacuum degassing and swelling treatment for 60 minutes, and further ensure that the pea dregs are evenly dispersed in the water through the vacuum degassing and swelling treatment, and then directly place the suspension in a 25MPa high-shear homogenizer for refinement treatment , Obtain the slurry containing dietary fi...

Embodiment 2

[0017] Wash the pea dregs with water to remove impurities and starch substances, add 10 times the amount of warm water at 40°C to the removed pea dregs to form a suspension, and then pre-pulverize the suspension before entering the vacuum degassing and swelling treatment 60 minutes, then the suspension is directly placed in a 30MPa high-shear homogenizer for refinement treatment to obtain a slurry containing dietary fiber, wherein the dietary fiber has a mesh number of 250 mesh, a material utilization rate of 100%, and a water holding capacity of 100%. It is 11g / g, the expansion force is 10ml / g, and the oil absorption rate is 0.8g / g.

Embodiment 3

[0019] Mix pea dregs and sweet potato dregs at a ratio of 1:1, then wash the mixed material with water to remove impurities and starch substances, add 9.5 times the amount of warm water at 38°C to the mixed material after removal of impurities to form a suspension, and then After the suspension is mechanically pre-crushed, it is subjected to vacuum degassing and swelling treatment for 60 minutes, and then the suspension is directly placed in a 28MPa high-shear homogenizer for refinement treatment to obtain a slurry containing dietary fiber, wherein the dietary fiber The mesh number is 230 mesh, the material utilization rate is 100%, the water holding capacity is 11g / g, the expansion force is 11ml / g, and the oil absorption rate is 0.78g / g.

Abstract

The invention provides a method for preparing dietary fiber pulp through wet processing type ultrafine grinding and belongs to the technical field of smashing. According to the method, grain dregs are taken as a raw material; firstly, the grain dregs are washed in water, so that impurities and a starch substance are removed; then, the pulp is formed by extracting and processing dietary fiber. The method is characterized in that the process of forming the pulp through extraction and processing of the dietary fiber is as follows: the grain dregs without the impurities are mixed with water, a suspension solution is formed, then the suspension solution is put in a high-shearing homogenizer for refining treatment, and the pulp containing the dietary fiber is obtained. The dietary fiber is subjected to refining treatment once with a high-shearing homogenization technique, the amount of equipment is reduced, and damage to the quality of the dietary fiber is avoided.

Description

technical field [0001] The invention belongs to the technical field of pulverization, relates to the technology of wet superfine pulverization, in particular to a method for preparing dietary fiber slurry by wet superfine pulverization. Background technique [0002] Dietary fiber refers to the general term of polysaccharide carbohydrates and lignin that are not digested by the human body. It mainly includes lignin, cellulose, hemicellulose, etc. Although dietary fiber is not absorbed in the human body, it has many beneficial effects on the human body. role, known as the "seventh nutrient". [0003] In the prior art, dietary fiber is mainly prepared by enzyme-alkaline method, wet method, and chemical method. In the prior art, the method for preparing dietary fiber by wet method is completed by multiple sets of equipment such as colloid mill and homogenizer, which relies on colloid mill In the early stage of abrasive grinding, the dietary fiber slurry is further pulverized un...
