What this category covers
This category brings together general process equipment used in pharmaceutical, chemical, food and cosmetic manufacturing. These products handle liquids, slurries and emulsions: separating solids, storing process fluids, filtering liquid streams and reducing particle or droplet size. They sit outside a single dosage-form line and serve many plant types.
Includes:
- ✓Pressure and gravity Nutsche filters for solid-liquid separation
- ✓Pressure vessels and storage tanks for process liquids
- ✓Inline homogenizers for emulsions and suspensions
- ✓Colloid mills for wet milling and dispersion
- ✓Bag filter housings, including duplex designs
- ✓Multi-stage filtration systems for viscous liquids
Excludes:
- ✕Tablet presses and capsule filling machines
- ✕Dry powder equipment such as blenders and sifters
- ✕Packaging and labelling machinery
Examples (not the full range):
- ›A pressure Nutsche filter for batch filtration
- ›A colloid mill for creams, pastes and food emulsions
- ›A duplex bag filter that runs through a bag change
What these products are used for
These products solve common process problems: separating solids from liquids, holding fluids under controlled conditions, keeping liquid lines clean, and making emulsions or suspensions stable and uniform. They are used by plants making active ingredients, specialty chemicals, inks, oils, creams, sauces and liquid formulations.
Buying, comparing, learning and reordering
Buyers usually arrive with a defined duty, such as a batch size, a liquid type or a filtration problem, and want a supplier who can build to it. Comparison searches focus on pressure versus gravity filtration, inline versus batch milling, and single versus duplex filters. Learning searches ask how each type works. Repeat buyers return for filter bags, cartridges, seals and additional units for new lines.
Key variations within this category
Capacity, from pilot-scale vessels to large production units
Material of construction, typically different stainless steel grades
Orientation and layout: vertical, horizontal, inline or batch
Operating mode: pressure-driven, gravity or vacuum-assisted
Continuous versus interrupted operation (single or duplex filtration)
Customisation level: standard models versus client-specific designs
Use cases and scenarios
An active-ingredient plant uses a Nutsche filter to collect product as a cake. A cosmetic maker passes a cream through a colloid mill for a smooth texture. An ink producer filters out particles before filling. A chemical plant stores solvents in a pressure tank. A food processor homogenizes a sauce inline instead of in batches.
How to choose
Start with the material being processed: its viscosity, solids content and corrosiveness decide the equipment type and steel grade. Batch equipment suits varied products; inline equipment suits steady, high-volume runs. Duplex or multi-stage designs cost more but avoid downtime. Custom-built units fit an existing line better, while standard models are usually quicker to supply. Smaller plants often start with flexible, multi-purpose units.
