While operators currently hand- wash the mill components, the company is actively working with the supplier to install a washer and tank system for automated washing. Stainless Technologies worked directly with Johansson's team from the initial project planning through commissioning and training. Stur- tevant provided engineering ser- vices, designed the 3D layout, pro- duced the piping and instrumenta- tion diagram (P&ID), and consulted on the installation of the PLC and human-machine interface controls. The project took approximately a year to complete from initiation to facility startup and commissioning. Equipment that handles materi- als intended for human or animal consumption must be regularly washed down and cleaned, which requires a quick-clean design and stainless steel product contact parts. Since the equipment was intended to mill lactose, the supplier designed the mill to meet USDA 3-A sanitary standards for independent washing and sanitizing of product contact parts. The mill features a Type 304 stainless steel rotor and liner and Type 440 stainless steel heat-treated mill blocks. "To achieve pharmaceutical- grade lactose, we recommended that a separate parts washing and sanitizing unit be installed near the mill per our drawings," said Johansson.
