High-Speed Softgel Capsule Production Line with Nitrogen Protection | Yundu Machinery
Nitrogen Protection Features Yundu’s softgel encapsulation line accommodates both traditional gelatin shells and plant-based (vegan) shells, making it ideal for nutritional softgels containing fish oils, botanical oils, omega-3s, vitamins, and other oxidation-sensitive actives. Softgel capsules inherently provide a sealed environment that shields the liquid fill from external factors. We augment this by providing inert nitrogen (N₂) blanketing at various points to protect these formulations. Industry sources specifically note that nitrogen is used to blanket oxygen-sensitive materials during manufacturing to prevent degradation. Our fill tanks and hoppers follow the same principle as pharmaceutical bulk tanks, which are engineered to expose “minimal air” to sensitive oil blends. In our design, the dual-layer feed hopper can be equipped with a nitrogen inlet so that air is purged from the mixing headspace. Likewise, our fill-storage tanks and metering systems can be supplied with nitrogen ports to maintain an inert environment during filling. The encapsulation
Rotary Bagging Machine | Pre-Made Bagging Machine for Coffee, Dog Food
What Is a Rotary Pre-Made Pouch (Bagging) Machine? Rotary bagging machines (also called pre-made pouch packaging machines) are automated systems that pick up pre-formed bags and, in one continuous cycle, open each bag, fill it with product, and then seal it. These machines use a circular (rotary) indexing table with multiple stations (often 4–12 stations) that coordinate bag handling, filling, and sealing. In simple terms, a bag is fed into an opening station, conveyed to a filling station, and then moved to a sealing station, all in a rotating sequence. This design yields high throughput – for example, many rotary baggers run at 50–100 bags per minute or more. Compared to vertical form-fill-seal machines (which form bags from film), rotary bagging machines are ideal when you have premade pouches (e.g. flat bags, doypacks, stand-up pouches, gusseted bags, zipper bags, or side-spout pouches). The machine ensures each bag is squarely opened (often using air
What Is Yundu’s Air Cushion Filling Machine? BB Cream Filling
Yundu is a premier Chinese manufacturer of liquid filling machinery with over 20 years of experience in cosmetics, pharmaceuticals, and food packaging. The company designs and builds all its machines in-house, focusing on value and reliability for customers. Its portfolio includes bench-top fillers, piston fillers, and high-speed automated lines. Among these are specialized foundation (cushion) filling machines – often called air-cushion-filling-machines – built to handle liquid foundation, BB/CC creams, and cushion cosmetics with precision. Yundu’s equipment is known for consistent, high-quality dosing and easy operation. Air-cushion makeup compacts (as shown above) have become hugely popular worldwide. In 2025 the global air-cushion foundation market reached about $2.8 billion and is projected to hit $4.6 billion by 2034 (≈6.8% CAGR). This boom is driven by the spread of Korean and global beauty trends and demand for portable, buildable-coverage products. In a cushion compact, a liquid foundation is stored in a sponge-lined “cushion” that releases product when patted
What Are Liquid-Filled Capsules? HPMC vs Licaps Explained
Liquid-Filled Capsules: HPMC vs. Licaps – Materials, Processes, and Machinery Executive Summary: Liquid-filled capsules are specialized hard-shell capsules designed to encapsulate oils, suspensions or semi-solids instead of powders. Licaps (a Capsugel/Lonza technology) are two-piece hard capsules (gelatin or HPMC) filled with liquid and hermetically sealed by a patented LEMS (Liquid Encapsulation Microspray Sealing) process. In contrast, standard HPMC capsules are plant-based cellulose shells usually filled with dry powders. This deep-dive covers material composition, filling processes, suitability for extracts, stability/leakage, regulatory certifications (GMP, HACCP, ISO), COA/testing parameters, application cases, and equipment (with emphasis on Yundu’s liquid capsule fillers). We compare capsule types in a table, outline workflows for powder vs liquid filling (and Licaps), and provide QA checklists and example COA fields. Throughout, we cite industry and manufacturer sources. Yundu’s NYF-1000 fully-automatic liquid capsule filler can handle liquids, suspensions or melts and seals capsules for enhanced stability. 1.

Where to Buy Dog Food Bagging Machines(vffs)?
Dog food packaging is no longer just about putting kibble into a bag. For modern pet food brands, packaging must protect product freshness, keep pellets from breaking, support attractive branding, and match the right production speed and bag format. That is why choosing the right dog food bagging machine is one of the most important decisions in a pet food production line. When people search for the best solution, they often compare three main packaging methods: fully automatic rotary pouch packaging machines for premium pre-made bags, VFFS machines for efficient roll-film packaging, and heavy-duty bagging systems for large-format packs. Among them, VFFS packaging is especially popular for mass production because it offers a strong balance of speed, efficiency, and cost control. This article explains what a dog food packaging machine is, how a dog food bagging production line works, how a vertical form fill seal machine operates, how it compares
