Máquina de encapsulamento de cápsula mole: Final 2026 Guia para fabricação eficiente de cápsulas softgel

Softgel capsules are gel-coated one-piece pills that can hold oils, liquid nutrients, ou suspensões. Ao contrário das cápsulas duras de duas peças, softgels are formed, filled and sealed in one continuous step. UM máquina de encapsulamento de cápsulas moles is an electromechanical system that spins two gelatin ribbons while injecting liquid fill between them. This ensures each softgel has a hermetically-sealed shell and precise dose. Neste guia amigável, we’ll explain how softgel machines work, outline the full softgel manufacturing process, and cover key features (capacidade, precisão, Conformidade com BPF) to help you choose the right equipment. Até o final, you’ll see why softgels are popular in pharmaceuticals and nutraceuticals, and how today’s automated lines (2026 edition!) can make production fast, limpar, and consistent.

Softgels are soft gelatin capsules filled with oil or liquid ingredients. A modern softgel encapsulation machine forms, preenche, and seals these capsules in one go. The result is a glossy, uniform capsule that is easy to swallow and airtight by design.

What is a Softgel Encapsulation Machine?

UM máquina de encapsulamento de cápsulas moles (also called a softgel machine or soft capsule machine) is a specialized rotary-die system for producing soft gelatin capsules.Unlike two-piece hard capsules, a softgel machine melts a gelatin/plasticizer mix into two continuous ribbons and seals them together around a precise liquid fill. In one step the machine forms the shell and injects the active liquid, yielding a one-piece watertight capsule. Softgel machines are essential in pharmaceutical and nutraceutical industries. Por exemplo, muitos óleo de peixe ou vitamin supplements are delivered as softgels, which are easy to swallow and effectively seal oils and sensitive ingredients.

Key components typically include a gelatin melter (to dissolve and liquefy the gelatin), casting drums (that form flat gelatin ribbons), um fill pump and injection wedge (metering the liquid fill), rotary die rolls (to shape and seal capsules), e conveyors/dryers (to remove moisture). Each part plays a role in producing uniform capsules. Modern machines are controlled by a PLC touchscreen, and built of stainless steel to meet BPF padrões.

Why softgels? Softgel capsules are favored in pharma and supplements because they can hold oils, suspensões, or sensitive liquids in a stable shell. They boost bioavailability and are easy to swallow. Because the shell is sealed, air-tight softgels protect oils (like fish oil or vitamin oils) and mask tastes. They also offer creative shapes and colors for branding. (Softgels are the clear capsules you see for vitamin E, omega-3.)

Softgel Manufacturing Process (Passo a passo)

O gelatin softgel capsules production line is a carefully orchestrated process. Aqui estão os main steps from raw materials to finished softgels:

• 1. Prepare a mistura de casca de gelatina: Gelatin powder (from animal collagen or vegetarian source) is mixed with a plasticizer (usually glycerin or sorbitol) and water in a heated tank. The mix is held under vacuum to remove bubbles and aged (often 3–24 hours) to reach uniform viscosity and temperature. A color or opacifier (dióxido de titânio) can be filtered in if needed. The result is a clear, elastic molten gelatin syrup ready for forming. High-grade (USP) gelatin ensures consistency.
  
• 2. Prepare o material de preenchimento: Simultaneamente, the active ingredients (Óleos, suspensões, emulsões) are blended in a stainless tank with mixers. Óleos (óleo de peixe, misturas de vitaminas) or gels are homogenized, and any powders (vitaminas, minerais) are milled fine (em volta 80 malha) ficar suspenso. Work under vacuum to remove air bubbles. Temperature is controlled (often 20–40°C) so the fill flows easily but won’t degrade sensitive components. Once uniform, the liquid fill is pumped into the machine’s fill hopper.
• 3. Ribbon Formation: The core of the process happens on the encapsulation machine. The warm gelatin syrup is pumped from the melter to two chilled casting drums. Each drum spins and evenly coats the molten gelatin into a thin ribbon (usually ~0.8 mm thick). Cooling fans or coolant channels on the drums solidify the gelatin into stable sheets. Now you have two parallel gelatin ribbons moving in sync toward the filling station.
  
• 4. Enchimento, Vedação, and Cutting: Just before the die rolls, a heated injection wedge injects a precise dose of the liquid fill between the two ribbons. A synchronized pump controls the fill volume to ±1–3% accuracy. Immediately afterward, o rotary die rolls press the ribbons together. The dies cut out capsule shapes (redondo, oval, oblongo, etc.) and fuse the edges of the gelatin around the liquid. Thanks to heat and pressure, the two layers of gelatin bond into one sealed capsule. Any excess gelatin (sucata) is scraped away. O resultado: individual, formed softgel capsules falling out onto a conveyor.
• 5. Separation and Conveying: As capsules exit the die area, a collection system (conveyor or chute) separates the finished softgels from leftover gelatin. A metal “scrap plate” guides trimmed edges away, so only capsules proceed. The conveyor gently carries the softgels to the drying unit. At this point each capsule is complete but still soft and moist inside.
• 6. Secagem e Polimento: Fresh softgels contain ~30–40% moisture. They enter a secadora (a rotating drum) where warm, clean air gently removes moisture. This may be followed by tray or cabinet drying for several hours to reach the final target moisture content. During drying, capsules become firm and shiny. Often a polishing or polishing drum applies a fine oil film to keep shells smooth. Depois de secar, the capsules are inspected and can be sorted, counted, and packaged.
  

Each of these steps is tightly controlled. Operators check ribbon thickness, preencher peso, and seal integrity throughout. Lab tests (burst tests, verificações de peso) ensure every batch meets specifications. The whole line must run at steady temperature and humidity (typically 20–25°C and 30–35% RH) to prevent shell defects. Resumidamente, softgel production is a precise, continuous process from start (matérias-primas) to finish (dried capsules).

Key Components of a Softgel Machine

A modern softgel line consists of specialized modules. Here are the main parts and their roles:

• Gelatin Melting Tank (Tanque de retenção): A heated tank melts and stores the gelatin solution. Temperature is precisely controlled (~65–70°C) and kept under vacuum to degas the mix. An adjacent gelatin service tank holds the molten gelatin at process temperature and feeds the machine via heated pipes.
• Fill Hopper and Pump: O medicine hopper holds the prepared liquid fill (oil or suspension). UM servo-driven pump or piston metering system then delivers an exact volume of fill to the injection wedge. Accurate dosing here (E.G.. ±2%) é vital. Systems often have heating/cooling to keep very viscous fills flowing smoothly.
• Spreader Box and Casting Drums: The spreader box sits above the rotating drums and evenly distributes the gelatin onto them. Each drum spins and cools the gelatin into a continuous sheet or ribbon. Proper tension and cooling fans ensure uniform thickness. The drums’ smooth rotation is critical – any hiccup can cause ribbon tears.
• Lubrication Rollers: Before the die assembly, lubricating rollers apply a very thin layer of vegetable oil (E.G.. MCT or light mineral oil) to each ribbon. This prevents the gelatin from sticking to the rollers or dies during sealing. Too much oil is avoided, as over-lubrication can prolong drying. This gentle coating ensures the ribbons glide smoothly into the die area.
• Injection Wedge: This is the heart of filling. A heater/nozzle wedge injects the liquid fill between the incoming ribbons immediately before sealing. The wedge maintains a temperature (higher if using plant-based gel) so the ribbons bond correctly after the fill is added. It must align perfectly; even minor misalignment causes leaks. Sophisticated machines monitor wedge pressure and timing to ensure every fill is placed into a forming pocket.
• Rotary Die Assembly: Two stainless steel rolos de matriz mesh together, each with cavities shaped as the final capsule. As the filled ribbons pass through, the dies press (and often slightly heat) the gelatin edges, sealing the capsule around the liquid. The die assembly also includes:

• UM stripper roller, which peels the formed capsules off the dies.
• Die brushing to remove any gelatin from the die surface.

• UM mangle roller to squeeze out excess gelatin scrap. The result is perfect, identical softgels.
• Conveyor and Dryer: Uma vez selado, capsules drop onto a stainless conveyor belt or chute. They move to a secadora, which gently agitates them as warm air passes through. Tumble drying removes most moisture. After tumbling, capsules may be placed on trays for final drying and polishing, leaving them firm and sparkly.
• Sistema de controle: A PLC touchscreen controls all operations: pump speeds, drum temperatures, die rotation, etc.. Alarms and sensors monitor temperature, níveis de vácuo, and capsule quality in real time. This automation makes high-throughput production possible with minimal operator intervention.

Understanding these parts helps in operation and troubleshooting. Por exemplo, a clogged nozzle affects fill weight, while a mis-timed die can cause bad seals. Regular maintenance of the spreader box, wedge, and rollers keeps capsules uniform.

How the Softgel Machine Works

Em termos práticos, um máquina de encapsulamento de cápsulas moles performs a continuous encapsulation cycle. Here’s a simplified sequence of actions during production:

1. Gelatin Flow: Warm gelatin flows from the melting tank to the spreader box, coating the drums to form ribbons.
2. Ribbon Formation: Each drum casts a thin sheet of gelatin. Cooling fans and drum jackets harden the sheets to the desired thickness.
3. Ribbon Alignment: The two ribbons converge at the center of the machine, one from each drum side.
4. Fill Injection: The injection wedge pierces between the ribbons and pumps a precise slug of liquid fill (óleo, solução vitamínica, etc.) between them. Each injection creates a cavity of fill.
5. Vedação: The ribbons, now enclosing fill, move into the die area. The rotary dies press them together, fusing the gelatin and cutting capsule shapes.
6. Capsule Ejection: Stripper rollers push the freshly made capsules off the dies onto a conveyor.
7. Lubrificação: Before sealing, the ribbons were lightly oiled to prevent sticking. Depois de selar, any tiny excess oil is often removed in subsequent drying.
8. Secagem: The capsules (still soft and moist) enter the dryer. After several hours of drying, their moisture content drops to a stable level.

This in-line method is efficient and produces consistent capsules. O rotary die process is the industry standard for softgels. Major manufacturers (Technophar, Há, JinLupacking) all use this design. Its continuous nature means high output: some modern machines make over 300,000 softgels per hour.

Softgel Capsule Manufacturing Checklist

When planning a softgel line or evaluating equipment, keep these factors in mind:

• Volume de produção: Match the machine size and number of dies to your output needs. Bench-top lab units (small scale) produce a few thousand per hour, while large production lines (with multiple die sets) can exceed 100,000–300,000 capsules/hour. Consider future growth – a slightly bigger machine might pay off in efficiency.
• Tamanho da cápsula & Forma: Ensure the dies support the capsule sizes you require (#0, #00, etc.) and shapes (redondo, oval, custom). Quick-change tooling is useful if you run varied products. Some producers demand non-standard shapes for branding; confirm the machine can handle your custom dies.
• Fill Material: Softgel machines are built for liquids or pastes. If your product is a dry powder, you’d need a hard capsule filler, not a softgel machine. For oils or suspensions, the machine must have a compatible pump (some pumps handle high-viscosity oils better). Ask about oil- and paste-specific pump options.
• Nível de automação: You can find semiautomático e Totalmente automático encapsuladores de cápsula mole. A fully automated line feeds gelatin and fill continuously and runs hands-off, ideal for large pharma plants. Semi-auto units may need more manual feed or stops for cleaning. For high demand, automated is best. (In a buyer’s checklist, SaintyCo emphasizes “you should go for fully automated Softgel encapsulation machine”.)
• Construção & Limpeza: Look for machines made of stainless steel (SUS304 ou SUS316) with polished finishes. All surfaces should be FDA/CE-compliant and easy to clean (rounded corners, no hidden crevices). Good machines are designed for fast changeover: tremonhas, bandejas, and dies that lift out for cleaning. This helps maintain strict hygiene. Consider how quickly you can break down the line for sanitation.
• Accuracy and Control: The machine’s fill pump and controls determine how precise your dosing will be. High-end machines use servo pumps and PLC control to hit tight weight tolerances (often ±1–3% of target). Built-in in-process checks (células de carga ou sensores) can detect underfills or overfills in real time. Clear HMI with touchscreens lets operators adjust settings quickly (velocidade, volume de preenchimento, etc.).
• GMP and Certifications: Para uso farmacêutico, equipment should comply with cGMP design. That means ultra-smooth welding (<0.8 μm polish), sealed motor enclosures, e materiais (like certified 316 steel) that meet FDA guidelines. Reputable machines carry CE marking (European safety standard), and may have UL/CSA as well. Ascender, por exemplo, designs its machines to cGMP standards for quality and safety. Always verify the supplier provides documentation of compliance and any necessary IQ/OQ/PQ validation support.
• Espaço & Utilities: Softgel lines can be large. Check the footprint and ensure your plant can accommodate the height (dryers can be tall). Also consider vacuum, water cooling (for drums), and power requirements. Some systems use a water-circulation vacuum pump to pull air from the gelatin; others use compressed air systems. Modern lines often come with UPS backup for critical controls.
• Equipamento de Apoio: Besides the encapsulator, plan for upstream/downstream equipment. You’ll need a gel melter tank, misturadores, peneiras, and possibly a colloid mill or homogenizer for your fill. A jusante, um polidor (to shine capsules), inspection machine (to sort rejects), and counting/packaging machines are common. The supplier should advise which extras are needed.

Resumindo, choose a machine that fits your capsule size, necessidades de saída, and product type. Balance performance (velocidade, precisão) against cost. Buying tips from experts include checking the brand’s track record, ease of changing tooling, and included services. A good supplier will guide you through lab testing, GORDO, and on-site commissioning.

Why Softgels? Benefícios e aplicações

Softgel capsules offer several advantages over other dosage forms:

• Improved Bioavailability: The liquid fill (often an oil solution) allows better absorption of fat-soluble nutrients (vitamins A, D, E, K, omega-3s). They can deliver faster or more consistent release of active ingredients than dry pills.
• Facilidade de engolir: Softgels have a smooth, rounded shape and feel. Many patients (especially children and elderly) find them easier to swallow than large tablets.
• Tight Sealing: Because the gelatin shell is hermetically sealed, softgels prevent oxidation of sensitive oils and mask odors/flavors. The airtight seal protects the fill from moisture and oxygen.
• Custom Branding: Softgels can be made in a variety of shapes (cylinder, triangular, etc.), tamanhos, and colors for brand differentiation. Additives in the shell can make them opaque or pastel-colored, which is harder with two-piece capsules.
• Versatile Fill: Unlike tablets, softgels can contain mixtures of liquids, suspensões, or soluble powders. This is great for botanical extracts or combination formulas that are easier to suspend in oil.

Industries that use softgel encapsulation machines include pharmaceuticals (vitaminas, fish oil drugs), nutracêuticos (suplementos), and even cosmetics (nutraceutical beauty oils). Por exemplo, plant-based gelatin or starch softgels are on the rise to meet vegan and halal markets. The machine’s ability to handle specialized fills (like aloe, CBD oil, essential oils) makes it a key asset.
