Embodiment Construction
[0060] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0061] like figure 1 As shown, the present invention provides a water jet mill 01 for superfine crushing of plants, and its structure includes: an upper feeding classification structure 011, a lower nozzle crushing structure 012, an upper feeding classification structure 011 and a lower nozzle crushing structure 012 is sealed and connected by bolts, and forms a flat ring tubular crushing chamber 0124 and a blade classification impact ring 0114 structure, wherein the flat ring tubular crushing chamber 0124 includes a multi-nozzle convergent crushing area and a multi-point tangential impact crushing area with uniform nozzles .
[0062] like Figure 1 to Figure 7 As shown, the diameter of the outer wall of the flat ring-...

The invention relates to a water jet mill for superfine crushing of plants, comprising an upper feeding grading structure and a lower nozzle crushing structure, the upper feeding grading structure is sealed and connected with the lower nozzle crushing structure, and the upper feeding grading structure Between the crushing structure of the lower nozzle, there is a flat annular tubular crushing chamber and blade classification impact ring. The invention strengthens the impact compression crushing, wall surface friction crushing and turbulent cavitation erosion crushing of high-pressure water jets, and utilizes the fiber structure of plants and the swelling and loosening effects of water to fully compress and stretch the stress of high-pressure water jets. At the same time, the inertial force of the blade flow channel and the vortex flow field is used to control the particle size in stages. The invention is specially designed for the ultra-fine crushing of plant fiber particles during extraction of natural plant active ingredients and extraction of essential oils and aromas, and can also be used for direct crushing of fresh plant leaves, flowers and fruits.
Description
technical field [0001] The invention relates to the technical field of ultrafine pulverization, and more specifically relates to an ultrafine water jet mill used for raw materials such as plant Chinese medicinal materials and essential oils. Background technique [0002] With the improvement of the health level of modern society and people's recognition of the concept of "returning to nature", more and more attention has been paid to medicines, food, health care and skin care products that use natural plants as raw materials. The extraction of essential oils and aromas of botanical spices is carried out through the so-called "cell wall breaking" of the roots, rhizomes, skins, leaves, flowers, fruits, and seeds of plants, and then using traditional extraction methods, such as decoction. , impregnation, percolation, reflux extraction, steam distillation, etc., or relatively new extraction methods, such as semi-bionic extraction, ultrasonic extraction, supercritical fluid extra...
