Tecpro Australia presents a new solution for the food and beverage industry to mix and maintain desired suspension levels during production. Traditionally, the food industry has relied on mechanical devices to keep solids in suspension. The new Tecpro eductors offer a simpler and more efficient way to achieve the desired outcomes.

The AISI 316 stainless steel eductors from Tecpro Australia are highly polished inside and out to prevent bacteria build-up and provide a hygienic solution.

Tecpro eductors were recently installed in large milk silos in a processing plant to keep milk solids in suspension. The eductors keep the solids in suspension in two ways. The eductors are strategically positioned in the silo to produce a continuous current, which cycles the product from the bottom to the top of the tank, preventing the solids from settling down and ensuring they remain in suspension.

In the second method, liquid is pumped through the eductors causing liquid in the vicinity to be drawn in, thereby mixing the induced liquid, which incorporates a high concentration of solids, with the pumped liquid. This system is ideal when fresh product is being added to the silo or to ensure the product is continuously circulated throughout the tank. Typically, the pumped liquid mixes with the induced liquid in a ratio of 4:1.

Being rough cast products, eductors were previously found unsuitable for use in the Australian food and beverage industry. However, the new Tecpro eductors have been polished to an RA (surface roughness) that is suitable for any application, with the new technique achieving the desired RA on both inside and outside surfaces. The highly polished, stainless steel eductors are now perfect for use in food and beverage manufacturing.

Designed with no moving parts, Tecpro eductors are completely maintenance-free. The pump used to move the liquid through the eductor is located outside the tank to further simplify maintenance.

Eductors are typically positioned close to the bottom of the tank and the total number of units required will depend on the characteristics of the application and turnover rate. Customers can seek advice from Tecpro Australia’s Technical Consultants on the size, location, orientation and number of eductors required for any application.
