Abstract
The invention relates to a technology for crushing a medium material by using high speed airflow. The technology comprises the following steps: 1, adding the medium material into an airflow crusher crushing chamber, and setting a granularity requirement; 2, impacting the medium material by high speed airflows generated by a plurality of nozzles of the airflow crushing chamber to make the medium material mutually bumped and rubbed under the action of the high speed airflows and crushed in order to realize micronization; and 3, separating through a grader, discharging and collecting the medium material with qualified granularity with airflow, returning coarse grains to the crushing chamber, and continuously crushing until the preset granularity requirement is met. Compared with the prior art, the technology has the advantages of fine granularity and narrow and uniform particle size distribution of the crushed material, and no influences on the activity of temperature-sensitive components due to the crushing temperature not exceeding 40DEG C. The particles are fine, so the prepared medium has good dissolvability and good quality. A totally closed self bump crushing mode adopted in the invention reduces the pollution possibility.
Description
Technical field
The present invention relates to a kind of technique of crushing material, specifically use high velocity air to pulverize the technique of culture medium material.
Background technology
While making culture medium, substantially adopt at present ball-milling method comminuting matter.Ball-milling method has that output is large, the simple advantage of technique, but also has larger, the inhomogenous shortcoming of material particular diameter of pulverizing.And can produce heat in crushing process.These heats can exert an influence to the activity of some temperature-sensitive component, and then affect the quality of culture medium.Part adopts screen cloth method or high-speed physical polishing to pulverize culture medium material now, and its crushing process also can generate heat, and also has the problems such as thermal sensitivity goods are unstable, finished particle is thicker.
High velocity air crushing technology of the present invention has that production scale is large, speed of production is fast, goods are stable, finished product can be accomplished the advantages such as nanoscale, and production process caloric value is very little, does not substantially affect the activity of temperature-sensitive component.So are good solutions for the problems referred to above.
Summary of the invention
The present invention, for solving existing problem, aims to provide the technique of using high velocity air to pulverize culture medium material.
In order to achieve the above object, the invention provides a kind of technique of using high velocity air to pulverize culture medium material, comprise the following step: step 1: culture medium material is added to Jet Mill, and set granularity requirements; Step 2: the high velocity air that an air-flow crushing number of chambers nozzle produces impacts culture medium material; Culture medium material collision mutually, phase mutual friction under the effect of high velocity air are consequently broken, and realize ultramicro grinding; Step 3: by the sorting of grader, the culture medium material that meets granularity requirements is discharged and collected with air-flow; The pulverizing chamber that is fed back to coarse granule continues to pulverize, until meet the granularity requirements of setting.
Compared to the prior art, the raw meal particle size that technique of the present invention is pulverized is thinner, particle size distribution is narrow and even; Temperature during pulverizing is no more than 40 ° of C, can not affect the activity of temperature-sensitive component.Because particle is thinner, the culture medium solubility property of making is better, and culture medium quality is also better.And the mode that has adopted totally-enclosed self collision crashing, has reduced contaminated possibility.
