NJP-260L liquid capsule filling machine for hard capsules — NJP-260L liquid capsule filling machine. Final output and fill performance depend on the qualified formulation, capsule, dosing and sealing configuration.

Project boundary

Start with formulation and shell compatibility

A liquid capsule filling machine separates hard-capsule bodies and caps, meters a defined liquid or suspension into the capsule body, closes the capsule and discharges it for the next process. It is not a universal route for every liquid. Shell material, water activity, solvent system, viscosity, temperature, suspended solids and fill level must be reviewed together.

The NJP-260L is intended for defined liquid-filled hard capsule projects using hard gelatin or HPMC shells within an approved formulation window. Oils, qualified suspensions and temperature-managed semi-solid systems may be evaluated. A representative product trial should establish pump settings, dose repeatability, capsule integrity, cleaning method and the need for downstream band sealing.

Good fit

Qualified oil-based or suspension formulations
Production requiring automatic capsule separation and liquid dosing
Hard gelatin or HPMC capsules approved for the formulation
Projects with defined fill, closing and sealing acceptance tests

Confirm before quotation

Viscosity and working-temperature range
Water activity, solvent system and shell compatibility
Target dose, allowable variation and suspended-particle behaviour
Need for mixing, heating, pellet co-dosing or band sealing

Use another route when

The formulation attacks or softens the selected capsule shell
Small batches do not justify continuous automatic operation
Powder-only filling is the actual requirement
The project requires a different containment or aseptic boundary

Operating sequence

Four operations determine liquid-filled capsule quality

Feed and separate

Empty capsules are oriented, loaded into mould segments and separated into caps and bodies.

Condition the liquid

The formulation is held within its qualified mixing, temperature and viscosity window before dosing.

Meter the dose

The liquid dosing system delivers the approved volume into each present capsule body.

Close and transfer

Capsules are closed and discharged for inspection and, when required, downstream band sealing.

Liquid dosing station on the NJP-260L capsule filling machine — Dose trials should record formulation temperature, viscosity, pump setting and sample method.

Liquid holding and conditioning tank on the NJP-260L — The tank specification must match the required mixing and working-temperature window.

Capsule detection point before liquid dosing — Capsule-presence detection helps prevent dosing into an empty tooling position.

NJP-260L liquid capsule filling machine workbench — Review product-contact access, removal sequence, cleaning tools and drain points during the design review.

What to record during the formulation trial

Use representative capsule shells and enough formulation to reach stable operation. Record start-up rejects, fill-weight samples, capsule deformation, leakage observations, pump repeatability and cleaning recovery. A short demonstration without an agreed sampling plan cannot establish sustained output.

My insight: treat formulation temperature as a controlled process input. If viscosity changes during the trial, a stable pump setting can still produce a changing dose.

Review My Requirements

Filling versus sealing

A liquid capsule filling and sealing machine is a system decision

The NJP-260L fills and closes hard capsules. Depending on the formulation, capsule shell and leakage-risk assessment, the project may also require a separate capsule band-sealing step. Do not assume that mechanical capsule closing creates the same barrier as a qualified band seal.

01Confirm fill level below the capsule-body shoulder.

02Verify closing length and capsule integrity after discharge.

03Challenge the filled capsule at the agreed temperature and hold time.

04Define whether band sealing is required and who supplies the interface.

Liquid-filled hard capsules for sealing evaluation — Capsule appearance alone does not prove leak resistance. Use an agreed challenge and inspection method.

My insight: write the sealing decision into the URS before pricing. Otherwise one supplier may quote only filling while another includes band sealing, inspection and transfer—creating a false price comparison.

Capacity planning

Convert 260 capsules/minute into a usable batch plan

01Required good capsules per batch and per shift

02Verified trial rate at the approved liquid temperature

03Time for tank preparation, replenishment and start-up checks

04Sampling, cleaning, changeover and hold-time requirements

05Capacity of band sealing, inspection and downstream packaging

Planning formula

Good capsules per shift = verified stable rate × scheduled run time × agreed operating factor.

Do not calculate yearly output from the published maximum alone. Include material conditioning, line clearance, cleaning, sample checks, rejects and the actual downstream constraint.

Controls and utilities

Define the process interfaces before FAT

Utility / condition	Published requirement
Power	3-phase, 4-wire AC 380 V, 50 Hz
Vacuum	−0.02 to −0.06 MPa

Ceiling height	≥2.6 m manual feed; ≥2.8 m vacuum feed

Specify more than voltage

Define the liquid-tank heating and mixing functions, capsule presence detection, recipe fields, alarm history, user levels, external interlocks and safe recovery after a stop. If a band sealer or inspection device is included, document every handshake signal and reject responsibility.

Quotation scope

Compare a complete liquid-capsule project, not a fixed price

NJP-260L liquid capsule filling system configuration — The machine, liquid handling, tooling, auxiliaries and downstream sealing boundary should be itemized.

Require separate line items

01Base NJP-260L and selected control configuration

02Tooling for each capsule size and shell format

03Liquid tank, mixing, heating and dosing arrangement

04Capsule feeder, vacuum system and optional pellet device

05Band sealer, inspection, rejection and line interfaces

06Documents, FAT, packing, freight, installation and support boundaries

A public price without the formulation, capsule, tooling, sealing and documentation scope is not a reliable project budget. Ask each supplier to quote against the same URS and acceptance method.

Make the quotation comparable.
HIJ can separate the machine, tooling, liquid handling, sealing, documents and delivery scope.

My insight

The most useful FAT result is not “machine ran successfully.” It is a traceable data set: formulation condition, capsule lot, run duration, good output, weight samples, rejects, leakage observations and cleaning evidence.

Use the capsule filling machine FAT checklist and GMP validation guide to align engineering and quality teams.

Vacuum system for capsule separation — Confirm vacuum source, utility connections, maintenance access and included auxiliaries.

Liquid tank section for formulation conditioning — Define temperature, mixing and drainability requirements for the actual formulation.

Liquid-filled hard capsules for trial inspection — Use agreed sampling, leakage and hold-time methods to evaluate finished capsules.

Buyer questions

Liquid capsule filling machine FAQ

What can the NJP-260L liquid capsule filling machine fill?

It is intended for qualified liquid-filled hard capsule projects, including defined oils, suspensions and temperature-managed semi-solid formulations. Final suitability depends on formulation properties, capsule-shell compatibility, dosing trials, cleaning requirements and the approved project configuration.

What is the output of the NJP-260L?

The documented rated output is up to 260 capsules per minute, or 15,600 capsules per hour. Sustained good output depends on the formulation, working temperature, capsule, dose, inspection method and downstream sealing or packaging constraint.

Which capsule sizes can the NJP-260L run?

The published range is standard hard capsule sizes 00# through 5#, plus safety capsules A–E. Confirm every required shell, supplier and dedicated tooling set during the configuration review.

What liquid fill variation is specified?

The published technical value is no more than plus or minus 3% for doses of 300 mg or more. Other dose levels, viscosities and suspension systems require project-specific evaluation and an agreed trial method.

Does the liquid capsule filling machine also seal capsules?

The NJP-260L fills and mechanically closes hard capsules. Some formulations also require a separate capsule band-sealing process. The need for band sealing must be decided from shell compatibility, fill level, formulation behaviour and an agreed leakage challenge.

What utilities and room conditions are published?

The published configuration lists 3-phase 380 V at 50 Hz, vacuum from −0.02 to −0.06 MPa, compressed air of 0.06 m³/min at 0.3 MPa, water flow of 250 L/hour, air displacement of 300 m³/hour, room temperature of 21 ±3 °C and relative humidity of 40–55%. Confirm final connection points and destination standards in the approved drawings.
