Jinan Tianyu Cordyceps Cell Wall Breaking Machine, as the core equipment for deep processing of cordyceps, ensures the release of effective ingredients through precise wall breaking technology. However, in long-term use, equipment is prone to malfunction due to material characteristics, operating standards, or component wear and tear. This article focuses on four types of high-frequency faults, dismantling the causes and practical solutions to help users efficiently restore production.
1、 Wall breaking rate not meeting standards: precise adjustment from materials to parameters
Fault phenomenon
After breaking the wall, the detection of cordyceps powder showed a breaking rate of less than 85% (industry qualified standard), and some powders still retained intact cell structures, which affected the extraction of effective ingredients.
Common reasons
1. Improper material pretreatment: Cordyceps sinensis is not crushed to the appropriate particle size (it needs to be crushed to 2-5mm in advance), or the moisture content is too high (exceeding 12%);
2. Wall breaking parameter setting error: low speed (not reaching the recommended 2500-3000r/min of the equipment), or insufficient wall breaking time;
3. Wear of grinding components: The gap between the grinding wheel and stator exceeds 0.1mm, and the grinding force is insufficient.
treatment method
1. Optimize material pretreatment: Grind cordyceps to the specified particle size, and control the moisture content at 8% -10% through drying or air drying;
2. Adjust operating parameters: Adjust the speed to the recommended range according to the equipment manual and extend the wall breaking time (adding 5-10 minutes per batch to avoid excessive grinding);
3. Check the grinding components: Disassemble the cavity after stopping the machine, measure the gap between the components with a feeler gauge, replace the grinding wheel or stator of the same model if it exceeds the time limit, and test the wall breaking rate after replacement.
2、 Sudden increase in equipment operating noise: Focusing on lubrication and component installation
Fault phenomenon
When the equipment is running, the noise exceeds 75 decibels (about 60-65 decibels during normal operation), accompanied by metal friction sound or body vibration.
Common reasons
1. Oil shortage in transmission components: Insufficient lubrication in motor bearings, gears, and other parts, resulting in increased friction;
2. Loose grinding chamber: Long term use causes the fixing screws of the chamber to loosen, resulting in displacement and collision during operation;
3. Foreign objects mixed in: Cordyceps raw materials contain stones and metal debris, which produce abnormal noise during grinding.
treatment method
1. Supplement lubricating oil: After stopping the machine, disassemble the transmission parts and add equipment specific lubricating oil (such as 32 # industrial gear oil) to ensure that the lubrication covers the friction points;
2. Tighten the cavity screws: Use a torque wrench to tighten the cavity screws to the specified torque (refer to the equipment manual), manually rotate the spindle to check for smoothness;
3. Cleaning foreign objects: Turn off the power, disassemble the feeding hopper and chamber, clean up residual foreign objects, check whether the grinding parts are damaged, and replace accessories if necessary.
3、 Automatic shutdown of equipment: checking safety protection and power supply
Fault phenomenon
The equipment suddenly stops running, and the control panel displays fault codes (such as "E01" and "E02"), or there is no obvious prompt.
Common reasons
1. Overload protection triggered: The feeding amount is too large, and the motor load exceeds the rated power;
2. Abnormal temperature: The temperature inside the broken wall chamber exceeds 50 ℃ (thermal protection activated);
3. Power supply failure: Poor contact of power cord, or voltage fluctuation beyond the equipment's adaptation range (220V ± 10%).
treatment method
1. Reduce feeding amount: Feed in batches according to the rated feeding amount of the equipment (such as 5-10kg per time), remove excess materials from the chamber, and restart;
2. Cooling treatment: Wait for the chamber to naturally cool to room temperature (about 30 minutes), check if the cooling fan is running properly, and clean the fan dust if necessary;
3. Check power supply: Replace the power cord, use a multimeter to check the voltage, ensure it is stable within the appropriate range, and use a voltage regulator when the voltage is unstable.
4、 Powder discharge blockage: unclogging channels and adjusting materials
Fault phenomenon
After the wall breaking is completed, the powder cannot be discharged from the discharge port, or the discharge speed slows down significantly.
Common reasons
1Blockage of discharge channel: Cordyceps powder gets damp and clumps, sticking to the inner wall of the channel;
2. Negative pressure system malfunction: The negative pressure fan of the equipment is damaged or the air volume is insufficient, making it unable to assist in discharging;
3. Material too fine: Excessive grinding leads to powder particle size being too small (below 100 mesh), which can easily cause dust blockage.
treatment method
1. Clearing the discharge channel: turn off the power, remove the discharge pipe, blow off the blocked powder with compressed air, or clean the inner wall with a soft bristled brush;
2. Maintenance of negative pressure system: Check if the fan wiring is loose, replace damaged fans, and adjust the air volume to the recommended value;
3. Adjust grinding parameters: appropriately reduce the speed or shorten the wall breaking time, control the powder particle size between 80-100 mesh, and avoid clogging due to excessive fineness.
