Equipment for crystallization comes in many different forms. A crystallizer is a machine that dissolves a chemical compound in a solvent, allowing the precipitation of crystals. Evaporation and crystallization equipment is used in industrial chemical engineering to create a variety of crystallized products, including table salt, sugar, and urea, as well as other specialized compounds.

Industrial crystallization equipment generally works through one of two main processes, either evaporation or cooling, although hybrid systems do exist. Whatever sort of crystallizer design you're looking for, you can find a crystallizer manufacturer offering a variety of options:

1. Find a crystallizer manufacturer offering equipment for a variety of applications.
2. Buy a draft tube crystallizer.
3. Work with a crystallizer manufacturer to engineer a custom batch crystallizer for your company.
   

Action Steps
The best contacts and resources to help you get it done

Find a manufacturer offering an array of evaporation and crystallization equipment

If you're not sure what sort of equipment your business requires, look for a manufacturer offering an array of products. Browse website listings to compare evaporators and crystallizers, or contact the manufacturer directly for information about the different kinds of machinery offered.

I recommend: Alaqua produces a number of varieties of evaporators for use in crystallization, including rising and falling film evaporators, plate evaporators, compact evaporators and more. Buflovak manufactures evaporative, tubular and surface cooled crystallizers for both continuous and batch crystallization processing.

Reap the benefits of a draft tube crystallizer

A draft tube baffle, or DTB, crystallizer offers a number of advantages over other types of industrial crystallization equipment. DTB crystallizers offer greater control over crystal size and are generally used in the production of large crystalline materials for the fertilizer industry like ammonium sulfate and potassium chloride. A draft tube crystallizer is capable of producing large singular crystals with a minimum of variance in product size when producing larger batches.

I recommend: GEA Process Engineering offers a wealth of information on their website about draft tube crystallization process, as well as a form to request more information about engineered products. They manufacture a variety of equipment both in the US and worldwide. Swenson Technology has experience manufacturing an array of evaporation and crystallization equipment, including draft tube crystallizers. See their website for more information on the products they engineer or to contact a sales representative.

Contact a crystallizer manufacturer to custom design your crystallization equipment

The most important part of buying industrial crystallization equipment is that it suits your business needs. Whether you have space restrictions or need a specialized crystallization process, be certain you buy a crystallizer that works right for your company. Find a manufacturer that will work with you from design of a crystallizer through its installation at your facility.

I recommend: Armstrong Engineering Associates manufactures scraped surface crystallizers, which work as cooling crystallizers. These crystallizers can be designed in a variety of sizes and implemented in large or small installations. They offer a pilot testing program to determine whether their crystallizer equipment is right for your company. Aquatech is a custom manufacturer of a variety of evaporation and crystallization equipment.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Be sure you're getting a good deal when purchasing equipment. Submit quote requests to multiple crystallizer manufacturers and be sure to look for quality and service guarantees as well as low prices.
