Manual Capsule Filling Machine Guide: Sizes, Throughput, Cleaning and Who It Suits
Share
A manual 100-hole capsule filling machine lets a small team fill hard-shell capsules in batches of 100 using plates, an orienter, and a tamping tool, with no electricity required. It suits compounding pharmacies, small supplement makers, herbal producers, and pharmacy schools that need more consistency and speed than hand filling but do not have the volume to justify an automatic machine. This guide covers how to choose the right capsule size, what throughput to realistically expect, what materials and tolerances to look for, how cleaning works, and who this type of machine suits.
If you are still deciding which capsule size your formula needs, read our detailed capsule size guide (#000 to #5). For an overview focused on pharmacy labs, see How to Choose a Capsule Filling Machine. This article focuses on the practical decisions: workflow, output, cleaning, and fit for your operation.
How a manual 100-hole filler works
The process follows the same steps on most machines:
- Orient: empty capsules are poured onto the orienter, which turns them so they all drop into the plate the same way up.
- Separate: the caps are lifted off, leaving the bodies held in the base plate.
- Fill: powder is spread across the plate and worked into the bodies. A tamping tool compacts the powder so more fits and fill weight is more even.
- Scrape: excess powder is scraped off level with the plate.
- Close: the caps are replaced and pressed shut.
1. Capsule size: one machine, one size
Each plate set is machined for one capsule size, because the hole diameter must match the capsule body. The SciMed machine is sold in eight size variants: 000, 00, 0, 1, 2, 3, 4, and 5. You pick the size at purchase. If you routinely fill more than one size, plan on one machine per size or on extra plate sets.
| Size | Body diameter | Typical fill volume / weight |
|---|---|---|
| 000 | 9.9 mm | 1.37 mL / ~1,100 mg |
| 00 | 8.5 mm | 0.95 mL / ~750 mg |
| 0 | 7.6 mm | 0.68 mL / ~500 mg |
| 1 | 6.9 mm | 0.5 mL / ~400 mg |
| 2 | 6.4 mm | 0.37 mL / ~300 mg |
| 3 | 5.8 mm | 0.3 mL / ~240 mg |
| 4 | 5.3 mm | 0.21 mL / ~170 mg |
| 5 | 4.9 mm | 0.13 mL / ~100 mg |
Fill weight depends on your powder's density, so the weights above are a guide. Test-fill with your actual formula before committing to a size.
2. Throughput: what to expect
A trained operator can complete a 100-capsule cycle in a few minutes. The product page gives figures of about 3–5 minutes per 100 capsules and roughly 1,200–2,000 capsules per hour. Real output depends on:
- Powder flow: free-flowing powders fill quickly; sticky or fluffy powders take longer and may need an excipient.
- Weight checks: if you weigh samples from every batch, include that time.
- Operator experience: speed and fill consistency improve with practice.
- Changeovers and cleaning: between formulas, cleaning time adds up.
If you consistently need several hundred thousand capsules a month, a manual machine may become a bottleneck and an automatic system may be worth evaluating.
3. Materials and tolerances
- Stainless steel: stainless plates resist corrosion and stand up to repeated cleaning. Ask which grade is used.
- Hole tolerance: holes that are too loose let capsules tilt; too tight and they jam or crack. Tight, consistent machining gives cleaner separation and closing.
- Orienter: confirm one is included. Without it, loading 100 capsules by hand is slow.
- Accessories: a tamping tool and powder scraper are needed for consistent fills.
4. Cleaning and changeover
A machine that comes apart easily is quicker to clean and easier to inspect. The SciMed product page describes three levels of cleaning:
- Same product, next batch: remove residual powder and wipe with 70% isopropyl alcohol.
- Different formula: fully disassemble, wash, and sanitize. Some components can be autoclaved.
- Different capsule size: requires a different machine or a size-specific plate set.
Write a cleaning procedure that fits your operation and keep a record of each cleaning. If you also count finished capsules by hand, a stainless tablet and capsule counter tray is easy to clean alongside the filler.
5. Getting consistent fill weights
With a manual filler, fill weight consistency depends mostly on technique. A few habits help:
- Spread powder evenly across the whole plate before tamping, rather than piling it in the center.
- Tamp the same way every cycle, with the same number of passes and similar pressure.
- Scrape level so each body is filled flush with the plate.
- Check weights by weighing a sample of filled capsules from each batch on a calibrated balance and recording the results.
- Keep conditions steady: humidity changes how some powders flow and pack.

Regulatory requirements depend on what you make and where you sell it. Confirm the GMP and FDA requirements that apply to your product with a qualified regulatory consultant before you start production.
Questions to ask any supplier
- What steel grade are the plates made from, and what hole tolerance do you machine to?
- Is an orienter included, and is it matched to my capsule size?
- Which capsule types and brands have been tested in this machine?
- Can parts be fully disassembled for cleaning, and which parts can be autoclaved?
- Are replacement plates, orienters, and tools available, and at what lead time?
- Can I buy additional plate sets for another size, or do I need a second machine?
- What documentation comes with the machine (manual, materials information)?
Frequently asked questions
Can one machine fill different capsule sizes?
No. Each machine is made for one size. Order the size you use most, and add a machine or plate set for any other size.
How many capsules can I fill in a day?
At the listed 1,200–2,000 per hour, an 8-hour shift could produce roughly 10,000–16,000 capsules with a trained operator, less once you allow for weight checks and cleaning.
Does it work with vegetarian capsules?
The product page lists compatibility with hard-shell gelatin, HPMC, and pullulan capsules.
What powders fill best?
Free-flowing, dry powders. Sticky or moisture-absorbing powders may need a flow aid or drying. A formulator can help with difficult materials.
Do I need special approval to use this machine?
Requirements depend on your product and business. Confirm the GMP and FDA requirements that apply to you with a qualified consultant.
