Problems solved by technology

The defects of these methods are: firstly, the product is too thick; secondly, the length of some plant fibers is longer, and its product becomes floc, which is unfavorable for further dispersion and mixing; thirdly, the material is oxidized during processing, and the active ingredients Severe loss is not conducive to long-term storage
The traditional anti-oxidation method is to mix additives such as antioxidants in the material. Since the amount of additives added is very small, the dispersion uniformity in the entire material is not enough, and the additives cannot be evenly coated on the surface of the particles.

Embodiment 1

[0022] Embodiment 1, the dried pumpkin slices are pulverized at an impact velocity of 30 m / s by using an impact pulverizer, and the coarse particles are returned to the impact pulverizer to pulverize again after being sieved through 30 meshes; The machine is impacted for 20 minutes under the action of high-energy vibration impact of 6 times the acceleration of gravity, and the average fineness can reach 5 microns. During the pulverization process of the high-frequency vibration grinder, a mixture of 4‰ anhydrous sodium sulfite and sodium caseinate is added. It can achieve that the active ingredients of the ultra-fine pumpkin powder product will remain unchanged within the one-year validity period, and it has the effect of keeping the quality and freshness of the pumpkin fine.

Embodiment 2

[0023] Embodiment 2, under the impact velocity of 50 m / s, Ganoderma lucidum is roughly pulverized into flocs by using an impact pulverizer, and then entered into a high-frequency vibration grinder to impact for 60 minutes under the high-energy vibration impact of 5 times the acceleration of gravity , and then sorted in a centrifugal air classifier to make the average fineness of the Ganoderma lucidum powder reach 10 microns, and add a mixture of 2‰ trihydroxychalcone and sodium caseinate during the pulverization process, which can reach the ultrafine Ganoderma lucidum powder product Active ingredients remain unchanged for 6 months.

Abstract

The present invention belongs to the field of plant material processing technology, and is the combined processing method of superfine crushing and preservative coating of plant material. The method includes initial crushing of material in a impacting and shearing crusher, simultaneous particle coating and superfine crushing in high-frequency vibration and impacting grinding mode. The method adopts conventional apparatus, and the product has high fineness and good coating effect. The present invention is favorable to deep processing of plant product and prolonging the guarantee period of product.

Description

technical field [0001] The invention belongs to the technical field of processing plant materials, and in particular relates to a method for surface coating and quality preservation of plant materials in the process of superfine crushing. Background technique [0002] Plant materials are a combination of various dried crops and natural herbs. They contain complex components such as fiber, lignin, starch, gum and sugar. If the dry cell walls inside plants can be crushed, their bioavailability can be greatly improved. In order to effectively utilize its economic value, it is often necessary to carry out ultra-fine pulverization first, which can make some nutritious but difficult to digest and absorb materials into functional foods, and improve the preparation degree of traditional Chinese medicine. The traditional process of crushing plant materials is the impact shearing method, which puts the materials into a pulverizer that mainly uses high-speed impact and shearing to crus...
