Tecpro Australia stainless steel eductors

Click2Contact

Eductors from Tecpro Australia offer a simple way to mix and maintain desired suspension levels of solids. They are highly polished inside and out to prevent bacteria build-up. Recently installed in large milk silos in a processing plant, the special Tecpro Eductors are responsible for keeping milk solids in suspension.

The eductors are strategically positioned in the silo to ensure they produce a continuous current that cycles product from the bottom to the top of the tank. This prevents the solids from settling so they remain in suspension. Liquid is then pumped through the eductors, causing liquid in the vicinity to be drawn through the eductors and thereby mixing the induced liquid (which usually has a high concentration of solids) with the pumped liquid.

The system is suitable when adding fresh product to the silo or to ensure all product is continuously circulated throughout the tank. Typically, the pumped liquid mixes with the induced liquid in a ratio of 4:1. With no moving parts, the eductors are maintenance-free. While a pump is required to move the liquid through the eductors, it is located outside the tank, making maintenance easy.

The company has developed a technique to polish eductors to an RA (surface roughness) that is suitable for any application. The technique can achieve the desired RA on both inside and outside surfaces. This means it is possible to use highly polished, stainless steel eductors in food and beverage manufacturing.

The eductors are typically positioned close to the bottom of the tank. The number required will depend on the characteristics of the application and the turnover rate. Tecpro technical consultants are available to provide advice on the size, location, orientation and number of eductors required for any application.
