The beer brewing process produces a large amount of brewer's grains as a by-product. This grain has a high moisture content (over 80%), making it susceptible to spoilage and rancidity. Transporting and storing it is costly, and improper handling can cause environmental pollution. A brewer's grain dryer transforms wet brewer's grains into a stable, high-value commodity, bringing significant economic and environmental benefits to businesses.
I. Significant Economic Benefits
Dried brewer's grains (DDGS, soluble and insoluble dried distiller's grains) are a high-quality feed ingredient with exceptional nutritional value. Rich in protein, amino acids, vitamins, and trace elements, they are an ideal additive for livestock, poultry, and aquaculture feeds.
The drying process reduces the moisture content of brewer's grains from over 80% to 10%-12%, significantly reducing their volume and weight to one-fourth to one-fifth their original weight. This means one truck can now transport four or five truckloads of the same amount, significantly reducing transportation costs.
2. Stable and Superior Product Quality.
Professional dryers utilize optimal temperatures and air speeds for rapid and uniform drying. This effectively prevents protein denaturation, vitamin destruction, and other nutrient losses caused by prolonged high temperatures or uneven heating, thereby maximizing the original nutritional value of the spent grains.
