The maintenance and upkeep methods of the Cordyceps sinensis ultrafine grinder should be combined with its low-temperature crushing characteristics and the processing requirements of traditional Chinese medicine. The specific implementation points are as follows:
1、 Core maintenance process
1. Cleaning management
After each use, the residue in the crushing chamber should be immediately removed, and the inner wall and blade components should be wiped with a soft cloth to avoid powder clumping and affecting the subsequent crushing effect.
Disassemble the grinding disc, screen mesh and other components during weekly deep cleaning, clean the dust accumulation with compressed air, and focus on clearing the discharge outlet and filter channel.
2. Lubrication and Temperature Control
The bearing should be replaced with special lubricating grease No. 2 every 2000 hours (with a filling amount not exceeding 1/2 of the cavity), and calcium based lubricating grease should be added to the screw feeder every 4000 hours.
Monitor the bearing temperature during operation. If the temperature rise exceeds 50 ℃, immediately stop the machine and check the cooling system to ensure that the temperature during the low-temperature crushing process is ≤ 45 ℃.
2、 Key component maintenance
1. Monitoring of vulnerable parts
Check the wear of the blade/hammer every 150 hours, and inspect the integrity of the sieve every 300 hours. If the aperture is deformed, replace it immediately.
Regularly calibrate the speed of the graded turbine to avoid a decrease in grading accuracy due to bearing wear (target particle size ≤ 10 μ m).
2. Transmission system maintenance
Before the new machine is put into operation, it is necessary to check the tightness of the belt daily for 30 days and use a tension meter to ensure that the deflection of the drive belt is ≤ 15mm.
Perform concentricity calibration on the motor coupling every month, and reinstall if the deviation exceeds 0.05mm.
3、 Special maintenance requirements
1. Material pretreatment
Before crushing, it is necessary to manually remove metal impurities from the cordyceps. It is recommended to use magnetic separation equipment for pre-treatment first.
When processing cordyceps for the first time, 100g of low value medicinal herbs (such as licorice) should be used for trial operation, and the crushing fineness should be tested to meet the standard before formal operation.
2. Environmental control
Maintain a humidity of ≤ 40% and a temperature range of 15-25 ℃ in the operating room to avoid blockage of the crushing chamber due to moisture absorption and clumping of medicinal herbs.
Check the sealing of the electrical control cabinet every quarter to prevent dust from entering and causing short circuits in the circuit.
4、 Safety operation standards
1. Before maintenance, the power must be cut off and a warning sign must be hung. The operation can only be carried out after the rotor is completely stationary.
2. Use anti cutting gloves when replacing blades, and use explosion-proof tools when disassembling bolts.
3. Establish and maintain archives to record the replacement cycle of vulnerable parts, lubrication time, and fault handling records.
Through the above systematic maintenance, the Cordyceps sinensis ultrafine grinder can maintain a cell wall breaking rate of over 95%, while controlling the loss of saponin components within 2%. The overall equipment failure rate can be reduced by over 60%.
