New Applications of Drying Equipment in the Brewing Industry: Beyond Spent Grains Disposal

Dear Valued Partners & Friends,

Greetings from YiSheng Drying! As a professional supplier of industrial drying solutions, we have long been committed to helping the brewing industry solve pain points such as waste disposal, cost control, and quality improvement. We recently had in-depth exchanges with many brewery partners and found that drying equipment, which is traditionally used for brewers' spent grains (BSG) treatment, has more high-value and innovative applications waiting to be explored—covering raw materials, by-products, production processes, environmental protection, and high-value-added products. Today, we are pleased to share these new application directions with you, hoping to help your brewery open up new revenue streams and achieve sustainable development.

Harvested brewing grains (sorghum, wheat, barley, corn) usually have a moisture content of 25–35%, which is prone to mildew and germination during storage. Our hot air circulation, three-cylinder rotary, and intelligent temperature-controlled drying equipment can quickly dry the grains to a moisture content of 12–14% with a control accuracy of ±0.5%. This not only stabilizes the quality of raw materials and improves the liquor yield and flavor consistency but also breaks the dependence on natural drying, enabling stable production throughout the year. In addition, breweries can also provide grain drying services to external parties to create additional revenue.

For breweries, especially beer factories, malt drying is a key link affecting production efficiency and product quality. Our spray drying, vacuum drying, and low-temperature belt drying equipment can realize deep drying of malt, controlling the moisture content to 3–5%, which greatly improves the shelf life and crushing efficiency of malt. At the same time, we can also dry malt extract into instant malt powder through spray drying technology, which can be widely used as raw materials for baking, health products, and beverages—helping breweries expand their product lines and increase product added value through external sales.

Traditional BSG drying mostly aims at producing feed raw materials, with low added value. Our low-temperature flash drying, refractance window drying (RW), and vacuum drying equipment can gently dry BSG while retaining its protein, dietary fiber, polyphenols, and other nutrients. The dried BSG can be further processed into BSG protein powder, dietary fiber powder, baking powder, and plant-based raw materials—products whose price is 3–5 times that of feed-grade BSG, targeting high-value markets suchs as food, health products, and baking. This not only solves the environmental problems caused by BSG accumulation but also helps breweries create high-value-added product lines.

With the global emphasis on environmental protection and carbon neutrality, sustainable materials have become a new industry trend. Our drying equipment can cooperate with modification technology to dry BSG and process it into degradable packaging materials, bioplastic fillers, and environmentally friendly building materials. This enables breweries to get rid of the red sea of feed processing and enter new high-potential tracks such as packaging and building materials, realizing the full resource utilization of BSG.

Beer yeast, a by-product of the brewing process, is an underrated "gold mine" with extremely high utilization value. Our drum drying, spray drying, and vacuum belt drying equipment can process yeast sludge into dry yeast powder (nutritional yeast, baking yeast, feed yeast), and further extract yeast extract as a flavor enhancer, health product raw material, and probiotic raw material. Even yeast β-glucan and nucleic acid can be extracted for use in the pharmaceutical and cosmetic industries. The added value of yeast products is far higher than that of BSG, which can become the second major profit source for breweries.

In response to the high energy consumption problem of traditional drying equipment, we launched a superheated steam drying solution. This technology uses steam instead of hot air for drying, recycles secondary steam, and reduces energy consumption by 30–50%, lowering the drying cost per ton by 200–500 yuan. At the same time, superheated steam drying can avoid oxidation and scorching of materials, effectively retaining the nutrients and flavor of BSG and yeast. It fully meets the environmental protection and carbon reduction requirements of the European Union, Southeast Asia, and other regions, helping breweries achieve green and low-carbon production.

Brewing wastewater and sludge are important environmental protection challenges faced by breweries. Our paddle drying, disc drying, and low-temperature heat pump drying equipment can dry concentrated brewing wastewater into organic fertilizer or biomass fuel, and dry sludge to reduce its volume by more than 80%, making it easier to dispose of or recycle. This not only helps breweries avoid environmental penalties but also turns waste into treasure, achieving zero landfill and additional revenue.

The humidity of brewing workshops, cellars, and filling areas has a great impact on product quality and equipment service life. Our rotary dehumidification, low-temperature dehumidification, and closed-loop humidity control systems can stably control the environmental humidity, preventing condensation, mildew, and bacterial growth. This not only improves the hygiene level of production and meets HACCP and food safety standards but also reduces equipment corrosion, cleaning frequency, and microbial contamination, ensuring stable production.

To help breweries gain more competitive advantages, YiSheng Drying is constantly innovating drying technologies: intelligent drying + Internet of Things (IoT) enables remote monitoring, automatic temperature control, precise moisture control, and energy consumption optimization; multi-technology coupling (flash drying + fluidized bed, superheated steam + rotary drying, spray drying + vacuum drying) achieves dual improvement of efficiency and quality; low-temperature/mild drying technology effectively protects heat-sensitive nutrients, laying the foundation for the production of food-grade and high-value-added products. We are committed to providing customized drying solutions for each brewery, helping you solve practical problems and create more value.
