Standard Full Operation Workflow of NJP-1200C Capsule Filler
The complete operation workflow of the automatic capsule filling machine is divided into four standardized phases: pre-production safety inspection, power-on debugging & trial run, continuous automatic encapsulation production, and post-batch GMP shutdown & cleaning. Each phase contains detailed operating steps for cleanroom staff.
Phase 1 – Pre-Production Inspection & Safety Check Before Running Capsule Filling Machine
This step ensures equipment hygiene, mechanical safety and sufficient raw materials to prevent sudden shutdown during formal capsule filling production, complying with pharmaceutical GMP rules.
GMP Hygiene Disassembly Check
Take apart all material-contact parts of the capsule filling machine, including the powder hopper, filling molds, turntable die holes, capsule separation station and recycling filter tank. Clean residual powder from previous batches with purified water, fully air-dry and reassemble to eliminate cross-contamination risks.
Mechanical & Circuit Safety Inspection
Check all fasteners, linear guide rails and bearings of the capsule filler for looseness; add food-grade lubricant to transmission components. Inspect vacuum pump, dust collector and compressed air pipelines for air leakage, confirm stable air pressure at 5–7Kg. Test emergency stop buttons, safety doors and sensor switches to guarantee normal operation.
Raw Material Loading Preparation
Pour intact empty hard capsules into the capsule hopper of the capsule filling equipment; for large batch production, connect the optional JQS-A capsule vacuum feeder to realize automatic continuous capsule supply. Sieve powder/granule materials to remove agglomerates, then load raw materials into the vibrating butterfly hopper. Match QVC-1/QVC-2 vacuum powder lifting device to avoid repeated manual feeding for large-volume production.
Auxiliary Equipment Pre-Startup Test
Turn on the vacuum pump and dust collector matched with the capsule filling machine separately. Verify vacuum pressure stabilizes at 0.04–0.08Mpa and dust collector airflow reaches 210m³/h without abnormal noise.
Phase 2 – Power-On Debugging & Small-Batch Trial Run of Automatic Capsule Filler
After finishing pre-production inspection, switch to manual mode to calibrate filling weight and capsule separation effect, avoiding massive raw material waste caused by incorrect parameters of the capsule filling machine.
Power On & Low-Speed Idle Test
Switch on the main power supply of the capsule encapsulation machine, activate the Siemens PLC touchscreen system and enter manual operation mode. Start the lubrication pump for the turntable indexing box, run the capsule filler at low speed for 2 minutes, check if turntable rotation is smooth without jamming or abnormal vibration.
Capsule Size & Filling Dosage Calibration
Install matched mold dies according to target capsule size, lock all positioning pins tightly. Adjust filling depth via the touchscreen control panel of the capsule filling machine: smaller values represent lighter filling weight, larger values increase dosage. Fine-tune tamping pins to ensure uniform powder compaction inside capsules. Run 5–10 trial filling cycles, weigh finished capsules repeatedly and adjust parameters until filling deviation meets ±3%/±4% standard.
Trial Encapsulation Defect Inspection
Manually trigger the capsule separation station of the capsule filler to test vacuum splitting performance, confirm caps and bodies are fully separated without stuck capsules. Produce a trial batch of 500 capsules, inspect for loose locking, powder leakage, broken shells and empty capsules. Adjust the capsule locking plate and air cleaning pressure if defective products appear.
Save Custom Production Recipes
After the trial batch passes quality inspection, store all running speed, filling weight and air pressure parameters as a dedicated product recipe on the touchscreen of the automatic capsule filling machine for one-click recall in subsequent production batches.

Step-by-Step Automatic Encapsulation Cycle of Capsule Filling Equipment
Switch the NJP-1200C capsule filler to automatic mode, set operating frequency between 40–50Hz and press the start button. The 10-position integrated turntable rotates intermittently, completing six core cyclic encapsulation steps without manual intervention.
Step 1 – Capsule Feeding & Precise Orientation
Empty capsules fall from the hopper into the closed guide rail separation station of the capsule filling machine. Guide rail transmission uniformly arranges all capsules with caps upward and bodies downward; vacuum suction transfers aligned capsules into turntable die holes to prevent disordered stacking.
Step 2 – Vacuum Separation of Empty Capsules
At the separation station of the capsule filler, independent vacuum channels pull capsule bodies downward while fixing caps on upper molds, completely splitting caps and bodies. Sensors identify deformed or unseparated defective capsules and mark them for automatic rejection in the next station.
Step 3 – Multi-Stroke Quantitative Powder Filling & Compaction
The vibrating butterfly hopper of the capsule filling machine continuously supplies low-fluidity raw materials to the dosing disc. Multiple tamping pins perform gradual multi-layer compaction to form uniform powder slugs. The modular filling unit pushes compacted drug plugs into lower capsule bodies, while spilled excess powder is instantly absorbed by the negative pressure base and transported to the powder recycling tank.
Step 4 – Automatic Defective Capsule Ejection
Unseparated empty capsules, broken shells and under-filled defective capsules are ejected by ejection pins into a waste collection bin of the capsule filling equipment. Only qualified filled capsule bodies remain in lower dies and rotate to the locking station.
Step 5 – Capsule Alignment & Tight Lock Sealing
Adjustable slot-type locking plates precisely align filled capsule bodies and caps of the capsule filler. Balanced mechanical pressure tightly buckles caps and bodies to form sealed finished capsules; operators can fine-tune locking displacement without disassembling station pull rods.
Step 6 – Finished Capsule Discharge & Powder Recycling
Fully locked intact capsules are ejected from die holes into the finished product collection bucket of the capsule filling machine. Meanwhile, the integrated powder aspirator filters recycled powder from the negative pressure tank; clean filtered materials can be reloaded into the hopper for secondary production without re-sterilization.
The six steps circulate continuously with turntable rotation to realize stable high-speed automatic encapsulation. Operators only need to periodically replenish empty capsules and raw materials, and sample finished capsules for weight inspection at fixed intervals.
Phase 3 – GMP Standard Shutdown & Cleaning Steps For Capsule Filling Equipment
Once the target production batch is completed, follow standardized shutdown and cleaning procedures to protect the capsule filler and meet pharmaceutical hygiene requirements.
Sequential Shutdown Operation
First stop the automatic main machine of the capsule filling machine, then close the vacuum pump, dust collector and air compressor in sequence. Discharge all remaining finished capsules into collection buckets, classify and dispose of defective waste capsules. Empty residual powder from the main hopper and recycling tank to avoid material agglomeration during standby.
Disassembly & Deep Sanitary Cleaning
Remove all stainless steel material-contact components of the capsule filling equipment, including hoppers, filling molds, turntable dies and filter cartridges. Wash away powder residue with purified water and pharmaceutical detergent, then fully dry with clean compressed air; replace aging filter cartridges regularly.
Post-Cleaning Equipment Maintenance
Reassemble all cleaned components of the capsule filler, replenish food-grade lubricant to transmission parts, wipe the machine outer shell with anti-static dust cloth, close safety protective doors and cover the whole machine with dust-proof film for standby.
Production Batch Data Recording
Export full batch production data (total output, defective rate, running duration) from the PLC touchscreen of the automatic capsule filling machine, fill in workshop production logs to realize full quality traceability per pharmaceutical regulatory standards.
