What is the process principle of Ganoderma spore powder cell wall breaking machine?
Date: 2025-09-30Read: 4
The core process of the Ganoderma spore powder breaking machine is to physically or mechanically break the dense chitin outer wall (about 200 nanometers thick) of the spores to release active ingredients such as polysaccharides and triterpenes inside. According to different technical routes, there are mainly four types of process principles:
1. Mechanical wall breaking process
By applying impact or shear force to spore particles through high-speed rotating metal rods, grinding discs, or blades, the cell wall structure is directly destroyed. This process equipment has a simple structure and low cost, but during the wall breaking process, high temperatures (up to 80 ℃ locally) may be generated due to friction, resulting in the denaturation of some thermosensitive components (such as triterpenes), and the wall breaking rate is usually 85% -90%.
2. Airflow crushing process
Accelerate spore particles to supersonic speeds (300-500 meters/second) using compressed air, and achieve wall breaking through collisions between particles. This process has high efficiency, no metal pollution, but strict requirements for equipment airtightness and airflow uniformity, and high energy consumption, making it suitable for medium scale production.
3. Low temperature physical wall breaking process
By combining liquid nitrogen freezing (-196 ℃) with high-frequency vibration technology, the outer wall of spores is made brittle and then broken by mechanical force. The wall breaking rate of this process can reach over 95%, and the retention rate of active ingredients is greater than 95%. However, it requires a low-temperature system and the equipment cost is 3-5 times that of a mechanical wall breaking machine, making it suitable for product production.
4. Ultrasonic wall breaking process
The cavitation effect generated by high-frequency ultrasound (20-50kHz) forms a micro jet that impacts the spore wall in a liquid medium. The temperature of this process is controllable (<40 ℃), but the single processing capacity is small (usually<1kg/batch), and the wall breaking rate is about 90%. It is mostly used in laboratories or small batches of high value-added products.
5. Key considerations for process selection
Wall breaking rate and activity retention: Low temperature processes perform well in wall breaking rate (98%) and component retention (>95%), but mechanical wall breaking is more economical.
Capacity demand: Airflow crushing is suitable for continuous production (with a processing capacity of up to 50kg per hour), while ultrasonic technology is only suitable for intermittent small batch processing.
Cost control: The price of a single mechanical wall breaking machine is about 20000 to 50000 yuan, while low-temperature equipment requires 150000 to 300000 yuan, and investment needs to be balanced according to product positioning.
