The RENU™ Drying & Milling System

RENU™ (Rapid Extraction, Nutrient Upcycling) dries and mills in one quick step to transform and upcycle raw materials into powder. Because the RENU System processes material quickly without natural gas or extreme temperatures, it is energy efficient and has excellent nutrient retention of the input material. The resulting powders are pure, nutrient-dense, and ready for resale in many applications.

How It Works

Our technology’s six key components work together to create the ideal powder for each product and desired application.

RENU™ System Components

Completely customizable, depending on product and conditions; may be designed for inline or batched processes.
Complete system control with one-touch interface monitors the output and optimizes system performance; provides Clean-In-Place technology.
A single-pass system that conditions incoming air to provide the optimal environment for moisture extraction.
Proprietary, revolutionary milling process; simultaneously extracts moisture from raw material and powderizes while retaining nutrients.
Allows for controlled separation of extracted moisture from the final powderized product.
Fully customizable; may be operated manually or automatically.

GTF RENU™ uses six key components to powderize excess materials

Scalability

RENU™ can easily be joined together for larger installations and batch processing. Here, we show configurations for 1-, 3-, and 7-system installations. We can also design a custom, multi-system installation to fit your facility's requirements.

1-System Installation

Starting at 1,200 lbs. per hour, 1,000 ft²

3-System Installation

3,600 lbs per hour, 1,800 ft²

7-System Installation

8,400 lbs. per hour, 4,600 ft²

Alternative to Traditional Drying Methods

Traditional drying methods consume copious amounts of time, square footage, and energy, depending on the method used.

Freeze dryers take hours to complete a single cycle, requiring vast amounts of real estate and energy. Then, if powder is the desired end product, dried food must also be milled. In contrast, RENU™ dries and mills in seconds.
Spray dryers have high overhead costs due to their immense energy requirements and high maintenance costs. In addition, their extreme operating temperatures degrade vital nutrients. Because RENU™ does not “cook” materials and uses no external heat or gas, it has excellent nutrient retention.
The high temperatures required in drum drying reduce food’s sensory profiles are compromised. RENU's™ low run temperatures and high speed of operation result in powders with excellent color, flavor, aroma, and nutrient retention.
Hammermills have high power requirements and do not dry food, so they are best used for grains and previously dried foods. RENU™ dries and mills concurrently in a single step. It transforms foods with up to 99% moisture to powders with as low as 1% moisture in seconds.

Benefits of Powderizing Side Streams

Boost Your Bottom Line

Instead of paying to landfill excess materials or making pennies on the dollar for livestock feed, transform your waste into a new profit center by powderizing and upcycling your side streams.

Create Valuable Powders

The powdered dietary supplements market is valued at $35.9 billion—and growing. Fruit and vegetable powders contain polyphenols and antioxidants, retailing for up to $50/lb. Powders are also used as natural ingredients in foods and beverages, pet foods, beauty products, plant-based proteins, or natural fabric dyes.

Reduce Waste, Improve Sustainability

Rescue your side streams from landfills and achieve your corporate sustainability goals. Reduce our collective carbon footprint and make a positive impact on the environment.

Contribute to the Upcycled Food Market

Upcycled foods create new, high-quality products from surplus foods. Powdered side streams are perfect as nutritious ingredients in upcycled foods. Whole Foods Market named upcycled foods one of the top 10 food trends of 2021, and the upcycled food market is worth $52.9 billion and growing.

Feed People

GTF-milled powders are shelf-stable and nutrient-dense. Our powders can be reconstituted and mixed with indigenous foods to fill bellies and improve nutrition in food deserts and famine-impacted areas. GTF has formed a non-profit to use excess powders to feed hungry people around the world.

Benefits for GTF Powder Customers

The powders generated by our RENU™ System can be used in many products:

Vitamins
Supplements
Nutraceuticals
Upcycled Foods
Beverages & Sports Drinks

Food Ingredients
Spices
Pet Foods
Biomaterials
Biofertilizers

Why GTF powders are superior to what’s currently on the market:

Increased Nutrient Value

Because the GTF RENU™ System doesn’t use extreme temperatures, additives, or chemicals in the drying process, the resulting powders have excellent nutrient retention.
Better Quality

Our powders are extremely close to the plant from which they are derived, which gives them a high sensory profile, with brilliant colors, intense aromas, and true flavors.
Long Shelf Life

The GTF RENU™ System extracts up to 99% of moisture, resulting in extended shelf life. This is particularly helpful for long-range shipping and storage in humid environments. Our powders take urgency out of the equation.
Sustainability

Most companies are striving to be more environmentally responsible, setting lofty goals to that end. By buying GTF powders, you are participating in the circular economy, reducing food waste and the associated greenhouse gasses that result from rotting food in landfills.
