500L Stainless Steel Jacketed Crystallizer Reactor Tank with Agitator & Steam Heating

This 500L jacketed crystallizer reactor is built for processes where temperature control and slow, uniform cooling directly determine product quality. In crystallization work, the difference between a usable batch and an off-spec one often comes down to how evenly the jacket transfers heat and how consistently the agitator moves the slurry. We manufacture this unit with that reality in mind.

The vessel is made from 304 or 316L stainless steel, depending on your process chemistry. For food and chemical applications, 316L is the safer choice when chlorides or acidic media are present. We weld with full penetration and grind the internal welds smooth, so there are no crevices for product buildup. Interior surfaces are mirror-polished to Ra ≤ 0.6 µm, which makes cleaning and batch changeovers straightforward.

The steam heating jacket is designed for even heat distribution, and the same jacket can be switched to cooling water or glycol when the process requires controlled cooling for crystallization. Working pressure is rated for typical atmospheric and low-pressure operations, and the top cover includes a manhole, sight glass, and multiple nozzles for sensors, feeding, and venting.

The agitator is a paddle or anchor type with a PTFE or mechanical seal. For crystallization, slow-speed agitation is often preferred to avoid breaking crystals. We can adjust the blade design and motor speed to match your viscosity and shear sensitivity. If your process involves vacuum or pressure, we can reinforce the vessel accordingly.

This reactor is used in food processing for sugar crystallization, in chemical plants for salt and fine chemical recovery, and in pharmaceutical intermediates where batch consistency matters. Every unit is pressure-tested and documented before shipment.
