Managing brewery spent grain efficiently is becoming increasingly important for breweries seeking to reduce operating costs while improving sustainability. One of our customers recently upgraded their spent grain handling process by installing the HT200 Screw Press Dewatering Machine, achieving more efficient material handling and significant operational improvements.

The Challenge: Wet Brewery Spent Grain Creates Hidden Costs

Although spent grain is a valuable by-product of beer production, handling it in its raw state presents several operational challenges. Fresh brewery spent grain contains a high percentage of moisture, making it heavy, bulky, and difficult to transport.

Before installing the HT200, the customer faced several issues, including high transportation expenses, excessive storage space requirements, unpleasant odors during warm weather, and inefficient daily handling. They needed a continuous dewatering solution capable of processing spent grain reliably while reducing moisture before transportation and reuse.

Why the Customer Selected the HT200 Screw Press

After evaluating the customer's daily production capacity and the characteristics of brewery spent grain, our engineering team recommended the HT200 Screw Press.

The HT200 is designed for continuous industrial operation and offers several advantages for brewery applications, including stable processing performance, a compact installation footprint, low maintenance requirements, durable stainless steel screw and screen components, and processing capacity suitable for medium and large breweries.

Following installation, the equipment was integrated directly into the customer's existing spent grain discharge line without disrupting production.

How the HT200 Processes Brewery Spent Grain

The dewatering process is simple, continuous, and highly efficient.

Fresh spent grain is fed into the screw press through the inlet hopper. As the screw shaft rotates, the material moves forward while increasing mechanical pressure is gradually applied. Free water is squeezed through the stainless-steel screen, while the dewatered spent grain is discharged from the outlet with significantly lower moisture content.

By reducing excess water mechanically, the machine decreases both the weight and volume of the material, making transportation, storage, and downstream utilization much more economical.

Results After Installation

Soon after commissioning, the brewery experienced noticeable improvements throughout its spent grain handling process.

The reduced moisture content allowed the customer to decrease transportation frequency, lower logistics costs, and require less storage space. Material loading and unloading became easier, while the overall production area remained cleaner and easier to manage. Continuous machine operation also improved workflow consistency, reducing labor intensity and simplifying daily waste handling.

For breweries producing spent grain every day, these operational improvements translate into substantial long-term cost savings.

Creating More Value from Brewery By-Products

Instead of treating spent grain as waste, the customer is now able to utilize it more effectively after dewatering.

The processed material can be supplied for animal feed production, agricultural composting, organic recycling projects, and biogas generation. Mechanical dewatering improves handling efficiency while supporting resource recovery and helping breweries move toward more sustainable production practices.

Why More Breweries Are Choosing Screw Press Technology

As breweries continue to focus on improving production efficiency and environmental performance, mechanical dewatering has become an essential step in modern spent grain management.

The HT200 Screw Press provides continuous operation, reliable performance, lower operating costs, and an effective solution for converting wet brewery by-products into valuable reusable resources. By reducing moisture before transportation or further processing, breweries can improve overall operational efficiency while minimizing waste management expenses.

If your brewery is looking to optimize spent grain handling, the HT200 Screw Press offers a dependable and cost-effective solution for long-term performance.
