Application Capsule Types
1. The internal design of the mold turntable has been improved, using Japanese linear bearings to ensure equipment precision and extend service life.
2 . Features a button-mounted cam design with a pressurized atomizing oil pump to maintain lubrication in the cam groove and reduce wear.
3. Computer-controlled system with stepless frequency conversion speed regulation and digital display for convenient, clear, and intuitive operation.
4. Based on the flat surface beneath the dosing disc, a three-dimensional adjustment mechanism ensures uniform gaps, accurate dosing, and a filling accuracy within ±3.5%. (Using high-quality capsules can further improve the pass rate to ≥99%. This machine is suitable for filling both traditional Chinese medicine and Western pharmaceuticals.)
5. Equipped with safety protection devices for both operator and machine, including an automatic stop function when material runs out. This ensures stable operation and reliable safety, making it an ideal choice for pharmaceutical and health supplement manufacturers producing hard capsule preparations.

The NJP-800 is a high-speed machine with a rated output of up to 800 capsules per minute under optimal conditions with a free-flowing powder.
 it handles all standard gelatin or HPMC (vegetarian) capsule sizes: 00, 0, 1, 2, 3, 4, and 5. Changeover requires switching the dosing disc, bushings, and rectifying ring.
It is a highly automated machine featuring:
PLC with Touchscreen Interface:Â For setting speed, counting, and monitoring production.
Automatic Lubrication:Â Centralized oil lubrication system.
Vacuum System:Â For capsule separation.
Safety Interlocks:Â The machine will not operate if the main guard is open.
Auto-stop:Â Can be set to stop after a pre-defined capsule count is reached.
Weight adjustment is a critical, multi-step process:
Primary Adjustment (Dosing Disc):Â Select the correct thickness of the dosing disc (e.g., 4mm, 6mm, 8mm) for your target weight range.
Secondary Adjustment (Powder Bed Height):Â Use the adjustment knob to control the depth of powder in the feed hopper, which directly impacts the volume filled into the dosing bores.
Tamping Pressure (if applicable):Â Some models allow for adjustment of the tamping pins to compress the powder for higher weight and density, crucial for non-free-flowing products.
It is essential to keep:
Complete set of Change Parts:Â Dosing discs, bushings, and rectifying rings for each capsule size you use.
Seals and Gaskets:Â Especially for the vacuum system and lubrication lines.
Drive Belts:Â The main motor drive belts.
Fuses and Relays:Â Electrical spares as specified in the manual.
Vacuum Pump Filter:Â Spare filters for quick changeover.
The rated speed is a maximum under ideal conditions. Actual speed is often lower due to:
Powder Characteristics:Â Poorly flowing powders require slower operation to maintain fill weight accuracy.
Capsule Quality:Â Low-quality capsules may jam at high speeds.
Machine Wear:Â Worn parts can cause instability at the top end of the speed range.
Operator Preference:Â Often run at 80-90% of max speed for better stability and control.
Yes, this is a key advantage of the PLC system. The NJP-800 typically has batch counting functionality and can record the total number of capsules produced per batch. Higher-end configurations might offer more advanced data logging capabilities.
