LPG-200 Spray Drying Machine with SUS304 / SUS316 Food-Grade Contact Parts
In food and pharmaceutical production, hygiene is not a feature but a licence to operate. A spray drying machine that traps residue in crevices, sheds particles or corrodes will fail an audit and endanger the product. The LPG-200 is built from food-grade stainless steel with sanitary geometry throughout.
The Problem Customers Report
Auditors reject equipment with rough welds, dead corners or non-food-grade surfaces where bacteria can hide.
Metal-ion pickup from cheap steel discolors sensitive flavors and can push a batch out of specification.
Crevices and concentric steps make cleaning difficult, so residues from one product carry into the next.
Why It Happens
Ordinary carbon steel and low-grade stainless corrode under acidic or saline feeds, releasing ions into the product.
Rough welds and sharp internal corners create stagnant zones that cleaning fluids cannot reach.
Non-sanitary fittings let product accumulate at joints, becoming a microbial growth site over time.
Our Solution
All product-contact parts are made from SUS304 or SUS316L, chosen per the feed chemistry, so there is no corrosion or ion pickup.
Welds are ground and polished to a mirror finish, and pipes use arc-butt joints to eliminate dead angles that trap residue.
A sealed, dead-corner-free design with manholes and view ports gives inspectors clear access to verify cleanliness.
Documentation is prepared to support GMP and food-safety audits, covering material certificates and surface finishes.
Application Scenarios
It suits food plants producing dairy, infant formula, soup and beverage powders under strict hygiene rules.
It fits pharmaceutical and nutraceutical producers who need GMP-compliant drying equipment.
It also serves cosmetic and personal-care powders where contamination and metal pickup are unacceptable.

How to Choose the Right Model
Choose SUS304 for neutral feeds and SUS316L for acidic, saline or chloride-bearing feeds that corrode lower grades.
Confirm the surface-finish requirement with your quality team; mirror-polished internal surfaces support the tightest cleaning validation.
Check that the design provides full drainability, so no liquid pools after cleaning.
Ask for material certificates and a weld-inspection record if your audit requires documented traceability.
FAQ
Q: Which grade should I choose, SUS304 or SUS316?
A: Use SUS304 for neutral feeds. Choose SUS316L when the feed is acidic, saline or contains chlorides, since it resists pitting corrosion far better.
Q: Is the design GMP compliant?
A: Yes. The sanitary geometry, polished welds and full-drainage layout are designed to pass food and pharma GMP audits, with documentation available.
Q: Can you supply material certificates?
A: Yes. Mill certificates for the stainless steel and weld-inspection records can be provided for your quality file.
Q: How is the tower cleaned?
A: The dead-corner-free design supports manual cleaning and can be specified with CIP for automated wash-down.
