High Protein Ingredients

Yeast Derived Proteins

Bepex is a leader in equipment used to recover from brewer’s yeast and other spent yeasts – producing a superior and sustainable high-protein product from waste yeast.

Transforming Waste Yeast into Profitable Products

Spent brewer’s yeast can be an excellent source of high protein for animal feed and pet food products. But drying the yeast with a traditional spray dryer often produces a particle that’s too small for feed production. The Bepex PCX flash dryer provides greater control over particle size, while protecting the protein during drying. And all while using less utilities and floorspace in the plant.

A Better Dryer with More Control

Spent yeast production requires drying the yeast during processing – which can be costly and even damage delicate proteins. The Bepex PCX flash dryer dries water-laden,  non-pumpable materials, offering high capacity drying without excess heat generation which may damage protein production.  And unlike traditional spray drying, you’ll get more control over particle size – critical to supplying protein ingredients for pet foods and other applications.

Lower Operating Costs

The Bepex PCX dries non-pumpable, water-laden solids , requiring less utilities, and producing less emissions than traditional dryers – all in a compact footprint. That reduces operating costs and helps improve cap ex returns.

A Sustainable, Profitable Solution

The PCX operates very efficiently with lower utilities and emissions. That helps support corporate commitments to improved sustainability by reducing your environmental impact. You’ll also reduce your waste generation – transforming what was once considered production waste into a high-value product.

Better Yeast Protein Processing from Bepex


Drying yeast proteins without damage is a challenge in producing high protein ingredients. Led by the innovative PCX flash dispersion dryer, Bepex offers the industry’s broadest range of drying technologies. Bepex focuses on providing superior control over drying, lower operating costs, and high capacity in a compact footprint.  The result is a better product and better cap ex return than spray, rotary, ring, or other traditional drying technologies.

Process Development

Step 01


All new inquiries begin with a feasibility study. These studies aim to provide preliminary insights into the viability of a commercial process. Using as little as 100 grams of material, we can begin early process design, develop plans for pilot-testing and/or confirmation, and begin providing early economic estimates. Our experience across our wide range of technologies gives us a unique ability to provide quick feedback on the feasibility of your process.

Step 02


From our learnings, we’ll begin the process development work. The primary work in this phase takes place in the form of pilot-scale testing in our Process Development Center. Our pilot tests look a bit different than what you may have experienced in the past. Each test is designed to measure the system performance and feasibility rather than that of any single machine.

Each system is custom assembled for each test. Our goal is to provide as much of a pilot-scale simulation as possible while gathering scale-up data to deliver on commercial capacities. When a certain technology proves ineffective, we’ll draw from our range of options to determine if there is a better fit. The Process Development Center is our sandbox to build, test, and revise to ensure we get every detail right.

Step 03

Budget Evaluation

With a successful pilot simulation completed, we now have everything we need to scale up and provide proposals for capital equipment with included performance guarantees.

Step 04

System Design And Build

After receipt of the purchase order, we begin with both equipment and system engineering. Each proprietary technology we sell is custom-designed and built per application. We do not have any off-the-shelf units. At this stage, your exact system begins to take shape, including auxiliary equipment, process flow diagrams, process and instrumentation diagrams, safety provisions, and more.

Step 05


After delivery and installation of your new system, Bepex will provide a mechanical check to ensure everything is placed according to plan. This is followed shortly thereafter by system commissioning. This is where our pilot-scale simulations become invaluable, as our team of application engineers, controls technicians, and sales engineers begin working with your team to successfully bring your system online.

Step 06


At this point, you’re up and running at rate, producing a quality product, but our work doesn’t stop there. 

Following commissioning, Bepex remains a reliable partner, providing quality OEM parts, immediate field service, process optimization, training, system troubleshooting, and more. We have consistently had high customer retention rates, and we believe it is due in large part to our comprehensive approach to serving our customers long after the original sale.
