Located in Nanchang Xiaolan Economic‑Development Zone, Jiangxi Renzhichu Nutrition Technology Co., Ltd. is a provincial‑level high‑tech enterprise with over twenty‑year experience in infant‑and‑child nutrition‑food production. Its business scope covers research‑and‑development, automated manufacture and nationwide sales of infant milk powder, complementary rice cereals and all‑age nutritional food. All workshops are built to 100 000‑grade food‑GMP clean‑room specifications. Automated machinery for raw‑material transportation, filling and packaging requires high‑standard purified compressed‑air with zero‑oil content, low dew‑point and long‑run operational stability. Since compressed‑air makes direct contact with semi‑finished food goods, oil, water and particulate pollutants may trigger food‑safety risks. After upgrading its automated production lines in 2021, the company purchased complete Bonaisi 55 kW oil‑free water‑lubricated screw air‑compressor sets fitted with advanced drying assemblies. The system reliably supplies clean‑air at ‑60 °C low dew‑point and serves all automated food‑processing machinery.

The compressors have run reliably for five years since commissioning, experiencing zero unscheduled shutdowns and delivering non‑stop airflow. They resolve common‑industry troubles such as pipeline condensed water and bacterial growth in humid environments. The on‑site equipment supervisor commented: “Bonaisi oil‑free water‑lubricated compressors eliminate oil contamination at the source. ‑60 °C low‑dew‑point air prevents milk‑powder and rice‑cereal dampness. No major overhauls were needed within five years, and maintenance expenses are far lower than conventional compressors. Bonaisi is always our first‑choice supplier for new‑equipment procurement and maintenance services.”

Bonaisi oil‑free water‑lubricated screw air‑compressors are custom‑engineered for clean‑air‑demanding food and dairy‑processing sites. The oil‑free design complies with ISO8573 Class 0 clean‑air criteria. Advanced dehumidification hardware sustains ultra‑low dew‑point airflow and accommodates round‑the‑clock continuous manufacturing cycles. Durable hardware quality and a nationwide after‑sales‑service network render Bonaisi compressors the preferred air‑supply hardware for automated assembly‑lines operated by major domestic food‑processing enterprises.
