Import Brewers Spent Grains Dryer — Buy in wholesale FOB from Supplier in China

The Brewers Spent Grains Dryer from Zhengzhou Dingli New Energy Technology Co., Ltd. is a rotary drum drying system designed to reduce moisture in brewer's grains from an initial 60% (fresh, post-dehydration) to a final 12-15%. The model DLSG1409 operates at 380V with 34 kW total motor power, achieving a vaporisation rate of 0.45 tonnes per hour and a daily capacity of 21.6 tonnes. The unit employs a drying temperature of 250±30°C, which is relatively high for biomass materials and demands attention to protein denaturation and Maillard reaction impacts on feed quality.

The machine structure comprises a heat source, feeding equipment, rotary drum, discharge mechanism, induced draft fan, and power distribution cabinet, all mounted within a 5m by 15m footprint. The 15.5-tonne unit weight indicates substantial steel construction, typical for industrial rotary dryers handling fibrous, high-moisture organic materials. The source emphasises continuous operation and low maintenance, though no bearing specifications, drum rotation speed, or flight design details (single-pass versus triple-pass) are disclosed. The stated suitability for vinasse, white wine residue, and red vinasse suggests the drum internals are configured to handle sticky, proteinaceous slurries that adhere to surfaces.

Brewery operations and animal feed compounders represent the primary market, converting a waste stream with 80-85% initial moisture into storable, transportable feed ingredient. The nutrient preservation claim requires verification, as the 250°C air temperature exceeds thresholds where heat-labile vitamins (thiamine, riboflavin) and lysine availability may degrade. Buyers should request thermal efficiency data, specific energy consumption in kJ per kg water evaporated, and whether the heat source utilises natural gas, biomass, or coal, as this affects emissions compliance and operating cost in jurisdictions with carbon pricing.

Zhengzhou Dingli New Energy Technology Co., Ltd. is headquartered at No.12 Hongye Road, Zhengzhou, Henan Province, postal code 450001. The company carries a harbor trust tier with no recorded response rate or average response time in the available data. Henan Province hosts a significant cluster of drying equipment manufacturers, leveraging engineering expertise from the region's agricultural machinery and mining equipment heritage. The supplier's exact year of establishment, registered capital, and number of employees are not stated in the source profile.

The source description positions the firm as a producer of industrial drying systems with application across biomass, distillery residues, and organic waste streams. No information is provided about in-house fabrication capacity, welding certification (ISO 3834, ASME), or after-sales service network coverage. Buyers should request references from installed brewery dryer projects, particularly regarding reliability of the gear drive system, drum tyre alignment procedures, and availability of wear parts (seals, riding rings, thrust rollers). The absence of named clients or project locations in the source data means due diligence on actual operating experience is essential before committing to capital expenditure.
