In developing the Bio-Septic Feeder, Vibra Screw had at its service 50+ years of feeder experience and enlisted collaboration with micro-bacteriological specialists (pharmaceutical processors and equipment designers) to produce a sanitary feeder that is: functional, accurate (reliable/repeatable), easy, quick and effectively cleaned. Bio-Septic is a screw feeder that guarantees the pharmaceutical processor, and all sanitary material handlers, flexibility of selection and aseptic security.

Sanitary Construction
All stainless steel construction, internal and external, assures total non-corrosive and non-contaminated surfaces. Bio-Septic boasts carefully designed and polished surfaces (the entire machine, not just contact surfaces) to eliminate every crevice and bacteria trap.

Multiple motor options to choose from: multilayered, stainless steel finish coating process specifically for sanitary wash down or all stainless steel construction are optimally suited to the specific conditions of the pharmaceutical industry.

Simple Disassembly and Reassembly
To assure the least interruption of any sanitary process, Vibra Screw designed the Bio-Septic to be disassembled easily and rapidly without the need for hand tools. Cleaning and sanitizing with solvents, steam or detergents is a rapid procedure with the Bio-Septic modular design, so reassembly follows quickly.
