Agitated Dissolution Tanks
Agitated dissolution tanks are mixing vessels designed to rapidly and completely dissolve solid materials into liquid solvents through optimized agitation, temperature control, and solid addition systems. These vessels maximize dissolution rates while ensuring complete dissolution without residual solids or concentration gradients.
Why are Agitated Dissolution Tanks Needed?
Agitated dissolution tanks accelerate the dissolution of solids that would otherwise require extended time or remain incompletely dissolved. Effective agitation continuously exposes fresh solvent to solid surfaces, prevents particle settling and agglomeration, and maintains uniform concentration throughout the vessel. Proper dissolution is essential for consistent downstream processing.

Frequently Asked Questions (FAQs)
How do you accelerate dissolution rates?
Dissolution rate enhancement uses high-turbulence agitation to minimize the boundary layer at solid surfaces, elevated temperature to increase solubility and diffusion, size reduction of solids to increase surface area, and optimal solid addition rates. We design complete dissolution systems addressing all rate-limiting factors.
What systems prevent powder floating or clumping?
Powder wetting and dispersion is achieved through subsurface addition, powder induction eductors, high-shear incorporation zones, and appropriate addition rates. Surface-active agents may aid wetting. Our designs prevent the floating powder layers and fish-eyes that slow dissolution and compromise product quality.
Can dissolution tanks handle very viscous solutions?
Yes, we design dissolution tanks for solutions that become highly viscous as dissolution progresses. Close-clearance impellers, helical ribbons, or anchor agitators provide mixing as viscosity increases. Heated surfaces prevent cold wall crystallization. Variable speed drives adjust to changing viscosity throughout the dissolution process.
