LPG-120 PLC-Controlled Spray Drying Machine with Programmable
Parameters
Repeatability is what separates a pilot success from a production
guarantee. When temperature and atomization drift, two batches of
the same recipe come out different. A PLC-controlled spray drying
machine turns your process into stored, repeatable parameters that
any operator can recall with one tap.
The Problem Customers Report
Manual operation produces batch-to-batch variation, so quality
depends on which operator is on shift.
Tuning temperature and atomizer speed by hand wastes material
during startup and risks overheating the first minutes of a run.
When a successful trial needs to be scaled or repeated, there is no
reliable record to reproduce it.
Why It Happens
Inlet and outlet temperatures interact with feed rate and atomizer
speed; changing one by hand shifts the others, so manual control is
always chasing equilibrium.
An atomizer spinning at fixed speed cannot adapt to feed viscosity
changes, so droplet size wanders during a run.
Without stored recipes, every startup is a fresh experiment.
Our Solution
The LPG-120 uses a PLC to coordinate inlet temperature, outlet
temperature, feed rate and atomizer speed as one linked recipe,
keeping them in balance automatically.
Recipes are stored and recalled from a 10-inch touch screen, so a
validated process is reproduced exactly, regardless of operator.
Continuous feedback holds the outlet temperature within a tight
band, protecting sensitive products during the vulnerable start-up
phase.
Trend logging records each batch's parameters, giving you the data
trail a quality system needs.
Application Scenarios
It suits producers who need documented, repeatable processes for
regulatory or customer audits.
It fits multi-product plants that must switch recipes often and
reliably.
It also serves pilot and scale-up labs that must transfer a proven
recipe to full production without drift.

How to Choose the Right Model
List how many recipes you run. The more products and the tighter
your quality spec, the more a PLC with stored recipes pays off.
Confirm the outlet-temperature tolerance you need. Sensitive
products justify a tight ±2°C control band.
Check whether you need data logging for audits; if so, specify
trend records and exportable batch reports.
Ask about remote monitoring if your team supports lines from a
central control room.
FAQ
Q: How stable is the temperature control?
A: The PLC holds the outlet temperature within about ±2°C by
continuously balancing feed rate and atomizer speed against the
heating input.
Q: How many recipes can be stored?
A: The standard HMI stores dozens of recipes, and the count can be
extended if you run a large product portfolio.
Q: Can the unit log data for audits?
A: Yes. Batch trends for temperature, feed rate and atomizer speed
are recorded and can be exported for documentation.
Q: Is the PLC system hard to operate?
A: No. Recipes are recalled with one tap, so day-to-day operation
needs no programming knowledge.
Tell us your recipe count and temperature tolerance, and we will
configure a PLC spray drying machine that repeats your process
exactly, batch after batch.
