SFI Spray drying chambers

SFI is an experienced fabricator of custom spray drying chambers and associated equipment, building our first spray drying chamber in 1987. Since then, we have completed more than 50 spray dryer installations.

We partner with spray drying system professionals, serving as the fabrication arm while they work with the end user to design the chambers and custom stainless steel vessels to meet their specifications and application requirements.

As a stainless equipment fabricator, our specialties in this area include:

Spray dryer chambers
Bag houses
Cyclones
Penthouses
Bustles
Special ducting
Fluid bed assemblies
Stacks
Platforms

How Spray Drying Chambers They’re Made

SFI shop and field personnel are experienced craftsmen, building stainless steel vessels and equipment with a variety of options, such as:

Materials and finishes
Insulation and outer jackets
Ports and inlets
Supports (lugs, skirts)

And more…

In addition to fabricating new equipment, SFI also performs field inspections and can make field modifications & repairs to existing equipment.

Shop or field fabrication

Pressure vessels and reactors are typically shop-built in our facility, however, if circumstances require that they be built in the field, we can do that too. All SFI welders are ASME certified.

Modifications and Repairs

SFI is ASME certified to not only build new equipment, but also make modifications and repairs. These services include:

Inspection services
Make repairs as required or replace if necessary
Add or replace fittings
Replace manways

Field fabricated spray dryer chambers

Spray drying chambers are typically field fabricated. They are built on the ground in two sections (chamber and cone) and then set in structural steel by crane(s). The materials, and many components, are formed in our shop for assembly in the field.

Most spray drying chambers are used for drying various food or chemical products. It is common to see 2B or mill finish material with interior welds ground flush. Whatever the need, SFI remains flexible to deliver results and exceed expectations. We are experienced in areas such as

Stainless steel and other nickel based alloys available
Coordination and installation of explosion panels
Skirts and support lugs for installation in structural steel framework
Chambers for dairy service typically built per USDA standards
Design calculations based on pressure, temperature and seismic by in-house Engineers
Fabrication of equipment used with spray drying chambers
Other certifications and standards (ASME, API, UL-142, etc.)

In addition to fabricating new equipment, SFI also inspects and makes field modifications and repairs to existing equipment.
