1、 Preparation before operation

1. Equipment inspection
   • Component integrityCheck whether the spiral propeller, mold, discharge port, heating tube and other components are securely installed without looseness or cracks.
   • cleanlinessEnsure that there is no residual rice slurry or rice cake debris inside the device to avoid blockage or contamination.
   • Lubrication maintenanceApply food grade lubricating oil to the transmission chain, bearings, and other parts to reduce friction losses.
2. Preparation of raw materials
   • Rice slurry concentrationMix rice slurry according to equipment requirements (such as a water rice ratio of 1:1.2~1.5). If it is too thin, it may cause the rice cake to not form properly, and if it is too thick, it will increase the motor load.
   • preprocessing: If dry Rice noodles is used, soak it in advance until there is no hard core (about 4-6 hours) to ensure uniform water absorption.
   • Impurity filtrationFilter the rice slurry with a fine sieve to remove impurities such as stones and rice husks, and prevent damage to the equipment.
3. Power and Safety
   • grounding protectionEnsure reliable connection of equipment grounding wire to prevent leakage.
   • voltage stabilityUse independent sockets to avoid sharing with other high-power appliances and prevent voltage fluctuations from damaging the motor.
   • protective deviceCheck if the discharge port protective cover is installed properly to prevent burns or entanglement of clothing during operation.

2、 Monitoring during operation

1. Temperature and pressure control
   • heating temperatureAdjust the heating temperature according to the type of rice (usually 120-150 ℃). If the temperature is too low, the rice cake will become undercooked, while if it is too high, it will easily become burnt.
   • stress regulationObserve the pressure gauge to ensure that the pressure of the screw propeller is stable (0.2~0.4MPa). Insufficient pressure will affect the compactness of the rice cake.
2. discharge state
   • Appearance of rice cakeNormal rice cakes should have a smooth surface, no bubbles, and uniform color. If there is breakage or roughness, adjust the rice slurry concentration or heating temperature.
   • continuityThe discharge should be uniform and continuous. If there is any interruption or blockage, stop the machine immediately for cleaning to avoid motor overload.
3. Operating Specifications
   • Uniform feedingUse a quantitative spoon or conveyor belt to continuously feed and avoid clogging caused by pouring too much rice slurry at once.
   • Do not touchDuring operation, it is strictly prohibited to touch high-temperature or rotating components such as heating zones and screw propellers with hands or tools.

3、 Shutdown and maintenance

1. Shutdown process
   • Cutting off materials in advanceStop feeding 5-10 minutes before shutdown, empty the remaining rice slurry in the equipment to prevent coking.
   • Cooling and cleaningAfter the equipment has naturally cooled to below 50 ℃, disassemble the mold and discharge port, rinse with clean water, and brush off any residue.
   • rust prevention treatmentAfter cleaning, dry the equipment and apply edible oil to metal parts to prevent rust.
2. long-term storage
   • Dry environmentStore in a dry and ventilated place to avoid moisture causing circuit short circuits or component rust.
   • regular inspectionPower on once a month (10 minutes) to prevent the motor from getting damp or the transmission components from getting stuck.
3. Replacement of vulnerable parts
   • propellerCheck the wear condition every 3-6 months, and replace it if there are obvious grooves.
   • sealing ringReplace it every six months to prevent rice slurry leakage and damage to the motor.

4、 Safety taboos and emergency response

1. Prohibited acts

   • no-load operationIt is strictly prohibited to use spinning equipment without rice slurry, as it may cause overheating and deformation of the propeller.
   • unauthorized modificationDo not modify the circuit or heating system without authorization to avoid causing fire or electric shock.
   • Child operationChildren are strictly prohibited from touching the equipment to prevent accidental contact with high-temperature components or rotating mechanisms.

2. exception handling

   abnormal phenomenon	Possible reasons	Solution
   Rice cake burnt paste	Heating temperature too high or insufficient feeding	Reduce temperature and increase feeding amount
   Motor abnormal noise	Spiral propeller stuck or bearing damaged	Immediately stop the machine, clean the blockage or replace the bearing
   Leakage tripping	Damaged power cord or poor grounding	Check the circuit and re ground it
