Conical Vacuum Dryer / Tank Reactor PLC Control Pressure Vessel Engine Motor

This conical vacuum dryer and tank reactor combination is built for processes that demand both drying and reaction capabilities within a single pressure-rated vessel. We fabricate this unit in our own shop, which means you\’re dealing directly with the people who weld, machine, and test the equipment—no trading company in the middle.

The conical geometry is the key feature here. Unlike flat-bottom tanks, the cone directs product flow toward the discharge valve, which helps with complete emptying and reduces the chance of material hang-up. When you\’re running vacuum drying cycles, that shape also gives you a larger surface area per volume, which improves heat transfer and shortens cycle times.

We build the wetted parts in 304 or 316L stainless steel, depending on your process chemistry. The internal welds are ground and passivated, and we can electro-polish the product contact surfaces if your application requires it. If you\’re processing pharmaceutical intermediates or food ingredients, we can provide surface finish documentation and material certs to support your validation work.

The PLC control system manages both the reactor and dryer functions. You can program heating and cooling ramps, hold times, and vacuum pressure setpoints. The control panel also logs process data, which is helpful for batch reporting or troubleshooting when something doesn\’t look right. We can configure the system to run semi-automatically or fully automatically, depending on your operator skill level and process requirements.

For the pressure vessel portion, we design to your specified working pressure and design temperature. The vessel is equipped with a jacket for heating and cooling, and we can add internal coils if your process needs more heat transfer surface area. The mixing system—anchor, paddle, or helical—is matched to the viscosity and solids content of your material. A mechanical seal or stuffing box is available depending on whether you\’re working under vacuum or positive pressure.

This equipment is commonly used in fine chemical production, pharmaceutical API drying, food additive processing, and cosmetic base manufacturing. It handles materials that are heat-sensitive, viscous, or prone to caking.

Technical Specifications

FAQ

Q: Can this vessel handle both vacuum drying and pressurized reaction?
Yes. The vessel is designed as a pressure vessel with a vacuum-rated seal system. Just confirm your maximum working pressure and vacuum level when requesting a quote.

Q: How do I know if 304 or 316L is right for my material?
It depends on the chemical composition and concentration of your product. Chlorides, acids, and certain solvents require 316L. Send us your material safety data and we\’ll advise accordingly.

Q: What kind of mixing do I need?
For low-viscosity liquids, an anchor agitator is usually sufficient. For higher viscosity or solids content, a paddle or helical design works better. We need to know your product\’s viscosity range to size the motor and gearbox correctly.

Q: How do I clean the vessel between batches?
The polished internal surface and conical bottom make cleaning easier. We can add spray balls or CIP nozzles if your process requires automated cleaning.

Selection Checklist

Before you request a quote, have these details ready:

• What material will you process? What is its chemical composition and concentration?
• What batch volume and working volume do you need?
• What are your operating and design temperatures?
• Will you run at atmospheric pressure, under vacuum, or at positive pressure?
• What is the viscosity and solids content of the material?
• Do you require heating, cooling, or both?
• What mixing outcome do you expect?
• Are there specific cleaning, sealing, or compliance requirements?

These details determine the vessel configuration, agitator design, seal type, and control system. The more precise your information, the closer we can match the equipment to your actual production conditions.

Send us your process parameters—material, batch size, operating temperature, pressure requirements, and mixing needs—and we\’ll provide a suitable configuration and quotation.
