Working principle and characteristics of ultrafine pulverizer for traditional Chinese medicine decoction pieces
Date: 2025-06-16Read: 4
1、 Working principle
1. The synergistic effect of high-speed mechanical crushing and airflow
After entering the crushing chamber, the material is crushed by the strong impact, shear, and friction generated by the high-speed rotating movable disc (or crushing disc) and the fixed disc. At the same time, the equipment introduces high-speed airflow (up to tens of meters per second) to accelerate the collision and grinding between materials, achieving efficient crushing.
2. Low temperature environmental protection active ingredients
Some models integrate low-temperature systems (liquid nitrogen or water cooling) to lower the temperature of the crushing chamber to -50 ℃ to 45 ℃, reducing the toughness of medicinal materials and suppressing the heat of crushing, avoiding the degradation of thermosensitive active ingredients.
3. Dynamic grading control of fineness
The built-in grading wheel screens and crushes particles in real time. Standard micro powders (such as 800 mesh) are collected with the airflow output, while coarse powders are returned to the crushing area for cyclic processing to ensure uniform and controllable particle size.
2、 Core Features
1. Ultra fine crushing ability
The pulverization fineness can reach the micrometer level (1-100 μ m) or nanometer level, with a cell wall breaking rate of ≥ 95%, significantly releasing effective components within the cell, improving drug dissolution and bioavailability (efficacy increased by 14-40 times).
2. Low temperature protection technology
The combination of low-temperature environment and closed crushing process maximizes the retention of volatile components and thermosensitive active substances in medicinal materials, suitable for precious medicinal materials such as ginseng and Ganoderma lucidum.
3. Efficient grading and controllable granularity
The grading wheel precisely adjusts the powder fineness (such as 800 mesh) to meet the requirements of different medicinal materials and formulations, and the particle uniformity is better than conventional crushing.
4. Energy saving and environmentally friendly design
Variable frequency motor precise speed control (8000-28000 revolutions per minute), low energy consumption; The fully enclosed stainless steel structure complies with GMP standards, has no dust pollution, and supports CIP online cleaning.
5. Broad spectrum applicability
Hard mineral medicine, fibrous plant medicine, and viscous animal medicine can all be efficiently processed, breaking through the limitations of traditional crushing processes on the characteristics of medicinal materials.
Note: Although ultrafine grinding significantly improves drug efficacy, process parameters need to be adjusted for high sugar or oily medicinal materials to prevent sticking to the cavity.
