Choosing the right capsule filling machine depends on your budget, production scale, and capsule type. Whether you're a small pharmacy or large manufacturer, each machine type offers unique benefits. This guide compares manual, semi-automatic, and automatic capsule fillers. It helps you select the best option to optimize efficiency and dosing accuracy for your specific needs.
A capsule filling machine (also called an encapsulator) is pharmaceutical equipment that automates filling empty capsules with precise amounts of powders, pellets, or liquids containing active ingredients. These machines eliminate manual errors while producing hundreds to thousands of uniformly dosed capsules per hour for medicines and supplements. Modern models can be customized to handle diverse formulations, from fine powders to granulated materials.
To meet different production sizes and the need for automation in the medicine and supplement industries, several kinds of capsule filling machines are available. These machines are generally divided by how automated and complex they are, mainly into three groups:
Each type offers distinct advantages and considerations regarding production volume, labor requirements, and investment costs.
Automatic capsule filling machines are designed for high-speed, large-volume production of filled capsules. These systems automate the entire process, from handling empty capsules to accurately filling them with various substances like powders or liquids, joining the capsule halves, and discharging the finished product. Requiring minimal manual operation, they significantly increase efficiency and reduce the need for constant supervision.
For pharmaceutical and nutraceutical companies focused on large-scale manufacturing, automatic capsule fillers offer a reliable way to achieve consistent quality, minimize contamination, and maximize output.
Let's introduce the features and advantages of automatic capsule filling machines, using LTPM China's products as examples:
LTPM CapTop Series are fully automatic high-speed capsule filling machines with PLC control and HMI, featuring auto-alarm for malfunctions. Key parts use imported materials, suitable for 00#-5# capsules and powder/granule/pellet/tablet filling. Max. capacity up to 228,000 pcs/hr, high accuracy, GMP compliant.
Product Features
Longer machine life and better precision with direct import Japanese linear bearings.
Extended lifespan of parts due to good cam lubrication and increased oil pump pressure.
Enhanced machine stability and longer life by using a larger RU100 cam instead of RU83.
Easy operation and clear display with stepless frequency conversion timing.
Touch screen controlled switch prevents accidents during operation.
Accurate dosage control (around ±0.75%) and high capsule qualification rate (≥99%), suitable for both Chinese and Western medicine.
Safer and faster capsule control switch located outside the machine.
Automatic capsule fillers are manufactured to perform the following activities without the aid or supervision of an operator: orientation → separation → precision filling (tamping/dosator) → locking → ejection. These advanced systems deliver two key benefits:
Significant labor cost reduction through full automation
Enhanced production efficiency with outputs reaching 200,000 capsules/hour

Semi-automatic capsule fillers combine the best features of manual and fully automatic machines. They perform key operations like filling and capsule closing automatically through programmed controls, while still allowing manual adjustments when needed for small batches. Made with pharmaceutical-grade stainless steel, these systems meet strict hygiene standards and are easy to clean between different production runs.
These machines provide consistent, accurate filling while reducing labor needs compared to manual systems. Their durable construction ensures long-lasting performance with minimal maintenance. Pharmaceutical manufacturers value these machines because they can switch between automatic and manual modes, making them suitable for various production requirements while maintaining quality standards.
Here is an example of our semi-automatic capsule making machines:
The LTPM DTJ-V is an ideal semi-automatic solution for small-to-medium pharmaceutical production and hospital labs. Featuring programmable touch controls and stepless speed adjustment, it automates capsule positioning, separation, filling and locking with precise dosing accuracy. Constructed entirely of stainless steel for GMP compliance, it handles both powder and granular formulations efficiently while offering user-friendly operation.
Product Features
Production capacity: 12,000 capsules per hour
Uses 3 cycloid motors for low-noise performance (Less than 60dB (A))
Touch button operation with simple interface
Easy mold adjustment for capsule sizes 00-5
Full stainless steel body and Copper capsule feeder & locking parts
Maintains accurate filling for powders & grains
Semi-automatic machines combine manual preparation with automated precision through this optimized 8-step process:
Material Loading: Operators pour empty capsules into the hopper and fill the powder reservoir. The capsule sowing device then transfers capsules to the filling ring.
Precision Separation:A vacuum system cleanly separates capsule bodies from caps, with the body ring rotating into position for filling.
Automated Filling: When activated, filling nozzles descend while the rotary table and auger system work in tandem to deliver exact powder doses (±3% accuracy).
Secure Locking: After reassembling caps/bodies, the pneumatic system applies controlled pressure (15-20 psi) to seal capsules completely.
Finished Output: Ejector pins gently discharge capsules at rates up to 12,000/hour, ready for inspection and packaging.
Ideal for personal use or small-batch production, manual capsule fillers are hand-operated devices that fill 300-800 capsules per cycle. They consist of a loading tray, pin plate, and sealing mechanism, offering an affordable solution for precise, low-volume encapsulation of powders or granules. While simple to operate, output is limited compared to automated systems.
These machines suit pharmacies, clinics, and supplement makers needing exact small quantities. Their portability and low cost make them practical for occasional use, but they lack the speed (±800 capsules/hour) and consistency (±10% variation) of semi/fully automatic models for commercial production.
The manual capsule filling process begins with loading empty capsules into the machine's tray. The operator turns the front knob to properly align the capsules while pulling the long handle upward to separate the caps from the bodies. Pre-measured filling powder is then evenly distributed across the filling surface, and the exposed capsule bodies are pressed into the powder bed - with optional compression if required.
After filling, the operator carefully repositions the caps over the filled bodies. The locking lever is then pulled forward to securely seal each capsule. Finally, the completed capsules are systematically arranged on the tray and ejected from the machine, ready for packaging. This methodical process allows for precise small-batch production while maintaining complete operator control at every step.
Here's a concise comparison table of the three capsule filling machine types:
| Type | Advantages | Disadvantages |
|---|---|---|
| Manual Machines | Lowest cost No power needed, portable Ideal for R&D/small batches (<800 caps/hour) Simple operation | Lowest output High weight variation (±10%) Labor-intensive |
| Semi-Automatic | Medium capacity (5K-15K caps/hour) Better accuracy (±3-5%) Manual/auto mode switching GMP-compliant | Requires some operator input Higher initial cost |
| Fully Automatic | High-speed (20K-200K caps/hour) Best accuracy (±1-3%) Full automation IoT integration | Significant investment Requires technical training |
Selecting a capsule filler depends on production scale, accuracy needs, and budget. Manual machines suit small batches (less than 1,000 caps per hour), semi-auto fits growing businesses (5K-15K caps per hour), while fully automatic systems excel in mass production (50K-200K caps per hour). Consider powder type, capsule size, and compliance requirements.
For optimal results, match machine type to your output goals: manual for R&D, semi-auto for flexible mid-scale runs, and automatic for high-volume precision. Prioritize GMP compliance for pharmaceuticals and evaluate long-term ROI when investing in automation.
