# Microencapsulation equipment Laboratory and production-scale machinery — spray drying towers, laminar-jet encapsulators and drip-casting microsphere systems — that encapsulates active ingredients, probiotics, cells or flavors in a protective wall material, sold as capital equipment to pharmaceutical, food and biotech manufacturers by specialty equipment builders (Solutions Vobis, BRACE, Buchi, Changzhou Yongchang) rather than the finished encapsulated ingredient itself. Source: https://en.bioecon.ru/technology/bio-microencapsulation-equipment/ Updated: 2026-08-18 ## Overview and value chain Markers: [EC: EU Medical Device Regulation 2017/745 (encapsulated cell products) / FDA GMP equipment qualification | OECD: Industrial biotechnology | Regulator: FDA (USA), EMA (EU), NMPA (China)] Microencapsulation equipment is the capital machinery — not the finished encapsulated product — that manufacturers use to encapsulate an active ingredient, probiotic culture, living cell or flavor compound inside a protective wall material, at scales ranging from a benchtop laboratory system to a continuous industrial production line. The confirmed producers here sell distinct mechanical approaches to the same core problem: BRACE's drip-casting process forms uniform microspheres from solutions, emulsions or melts; Buchi's Encapsulator uses a laminar-flowing liquid jet break-up principle at laboratory scale; and both Solutions Vobis and Changzhou Yongchang build spray-drying-based systems that atomize a wall-material emulsion into hot air to form dried microcapsules. This is equipment sold to a manufacturer building its own encapsulation capability, distinct from a contract encapsulation service or the encapsulated ingredient itself — a buyer sourcing this category is purchasing a machine, not a product. The key directions of microencapsulation equipment are: 1. **Drip-casting microsphere production systems:** equipment using a patented drip-casting process to form highly uniform, perfectly spherical microgranules and microcapsules from solutions, emulsions, dispersions or molten masses, spanning development-scale to contract-manufacturing volumes (BRACE's Spherisator line). 2. **Laminar-jet laboratory encapsulators:** benchtop systems using a laminar-flowing liquid jet break-up principle to encapsulate microorganisms, cells, active pharmaceutical ingredients, flavors, vitamins and proteins for R&D-scale work across pharma, cosmetics, food and agriculture (Buchi's Encapsulator B-390/B-395). 3. **Custom-engineered pilot-to-production microencapsulation systems:** non-off-the-shelf, client-specific systems spanning pilot to full production scale, often bundled with adjacent particle-formation technologies (spray drying, crystallization, evaporation) within the same equipment builder's portfolio (Solutions Vobis). 4. **Spray-drying microencapsulation towers combining centrifugal atomization and fluidized-bed drying:** industrial towers that combine centrifugal atomization with fluidized-bed drying to control microcapsule particle shape and size, targeting probiotic, flavor, fragrance and oil encapsulation for food, pharmaceutical, pesticide, feed and cosmetic applications (Changzhou Yongchang's microencapsulation spray granulation tower). ### Sectoral value chain ``` [Wall-Material & Process Selection] ──> [Equipment Design/Manufacturing] ──> [Installation & Commissioning] ──> [Customer Microencapsulation Production] │ (Process Validation & Qualification) │ ▼ [Ongoing Equipment Service/Support] ``` ### Value chain levels | Level | Description | Key inputs/outputs | |:---|:---|:---| | **Wall-material and process selection** | Selecting the encapsulation mechanism (drip-casting, laminar-jet, spray-drying) and compatible wall-material chemistry for the target application. | **In:** Application requirements, wall-material candidates.

**Out:** Sustained equipment uptime and process performance. | Cross-cutting technologies of the sector: - **Mechanical approach as the core technical differentiator:** every confirmed producer's core intellectual property is the specific mechanical method of forming the microcapsule — drip-casting, laminar-jet break-up, or centrifugal-atomization-plus-fluidized-bed spray drying — rather than a shared underlying chemistry, since the wall material and core material vary by customer application. - **Scale span from laboratory to production as a business-model split:** producers position themselves across different points of a shared scale-up path — Buchi's Encapsulator targets R&D-scale work, while BRACE and Solutions Vobis explicitly span development through full production and contract-manufacturing volumes — meaning a customer's equipment choice often depends on where they sit in their own scale-up journey. - **Cross-industry application breadth on a shared mechanical platform:** every confirmed producer's equipment serves multiple end industries (pharmaceuticals, food, cosmetics, agriculture, feed) from the same underlying mechanical platform, since the equipment encapsulates whatever core and wall material the customer supplies rather than being locked to one industry's specific chemistry. --- ## US The United States hosts one confirmed producer of custom-engineered microencapsulation systems spanning pilot to production scale. ### Custom pilot-to-production microencapsulation systems - **Solutions Vobis:** designs and manufactures non-off-the-shelf, client-specific microencapsulation systems spanning pilot to full production scale, offered alongside adjacent particle-formation equipment (spray dryers, crystallization, evaporation and short-path molecular distillation systems) within the same equipment-builder portfolio. --- ## CN China hosts a confirmed manufacturer of spray-drying-based microencapsulation towers for food, pharmaceutical and agricultural applications. ### Spray-drying microencapsulation towers for food and pharmaceutical applications - **Changzhou Yongchang Granulation Drying:** a Jiangsu-based manufacturer of a dedicated microencapsulation spray granulation tower combining centrifugal atomization with fluidized-bed drying, targeting probiotic, flavor, fragrance and oil encapsulation for pharmaceutical, food, pesticide, feed and cosmetic applications, offering free pilot-scale trial production with customer-supplied material. --- ## EU Europe hosts a German drip-casting microsphere equipment maker alongside a Swiss laboratory-scale encapsulator manufacturer. ### Drip-casting microsphere systems and laboratory-scale encapsulators - **BRACE GmbH:** a German manufacturer (branded as "The Microsphere Company") using a patented drip-casting process to form highly uniform microspheres and microcapsules from solutions, emulsions, dispersions or melts, spanning development, contract manufacturing and dedicated machinery sales, certified to FSSC22000 food-safety standards. Buchi (Switzerland) is a fourth confirmed producer that falls outside the strict EU header (Swiss-headquartered, outside the EU): it manufactures the Encapsulator B-390/B-395, a laboratory-scale system using a laminar-flowing liquid jet break-up principle to encapsulate microorganisms, cells, active pharmaceutical ingredients, flavors, vitamins and proteins across pharmaceutical, materials-science, cosmetics, food and agricultural R&D applications. It is carried in the Leading Companies table below. --- ## Leading companies and research institutes | Company / Institute | Country | Key products / platforms | Tech features | Status 2026 | |:---|:---|:---|:---|:---| | **Solutions Vobis** | 🇺🇸 USA | *Custom microencapsulation systems* | Non-off-the-shelf, pilot-to-production scale | commercial | | **BRACE GmbH** | 🇩🇪 Germany | *Spherisator drip-casting microsphere systems* | FSSC22000-certified; development through contract manufacturing | commercial | | **Buchi** | 🇨🇭 Switzerland | *Encapsulator B-390/B-395* | Laminar-jet break-up, R&D-scale, multi-industry application | commercial | | **Changzhou Yongchang Granulation Drying** | 🇨🇳 China | *Microencapsulation spray granulation tower* | Centrifugal atomization + fluidized-bed drying, free pilot trials | commercial | --- ## Tech stack and innovations The stack centers on three distinct mechanical approaches to forming a microcapsule — drip-casting, laminar-jet break-up and centrifugal-atomization spray drying — with producers differentiating by which mechanism they've engineered and at what scale they position their equipment. 1. **Drip-Casting as a Route to Highly Uniform Spherical Microspheres:** - BRACE's patented drip-casting process is engineered specifically to produce highly uniform, perfectly spherical microgranules and microcapsules, a precision-shape claim distinguishing it from spray-drying approaches that typically produce a broader particle-size and shape distribution. - This uniformity focus is why BRACE's positioning spans from development work through contract manufacturing — the same core mechanical principle scales from small-batch precision work to larger production volumes without changing the fundamental particle-formation mechanism. 2. **Laminar-Jet Break-Up for Living-Cell and Microorganism Encapsulation:** - Buchi's Encapsulator uses a laminar-flowing liquid jet break-up principle specifically compatible with encapsulating living microorganisms and cells alongside conventional active ingredients, a gentler mechanical process than high-shear or high-temperature alternatives that could damage living material. - This cell-compatibility is a meaningful technical differentiator for R&D applications working with probiotic bacteria or other living biological material, where a producer needs an encapsulation method that preserves viability rather than just forming a capsule around an inert ingredient. 3. **Centrifugal Atomization Plus Fluidized-Bed Drying for Industrial-Scale Throughput:** - Changzhou Yongchang's spray granulation tower combines centrifugal atomization (which forms the initial emulsion droplets) with fluidized-bed drying (which controls final particle shape and size) as a combined process specifically engineered for continuous, automated industrial-scale production. - This combined-mechanism approach is positioned for high-throughput commercial manufacturing (probiotics, flavors, oils) rather than the R&D-scale precision work Buchi's laboratory encapsulator targets — the two producers serve different points in a customer's development-to-commercial-scale pathway. --- ## Value chains and production pipelines ### Industrial pipeline of a bio-microencapsulation-equipment product line ``` ┌───────────────────────────┐ ┌───────────────────────────┐ │ 1.
