What's New
Machine Vision for Inspection of Thin Films and Membranes


Edit
Mainstream is developing the new and innovative The Mantis Eye. A customizable machine vision system for automated, continuous monitoring of thin films and membranes. The patent-pending optical design provides simultaneous film thickness mapping and defect detection. It samples the entire web width in real-time (100% inspection) and can be used on coating lines and other web converting equipment. The guiding principle of our product design is to provide the finest defect and thickness resolution with reasonably priced camera hardware. The idea is to provide a better value product instead of the brute force method of expensive cameras that bog down systems with huge images and data management issues.

Biomass Conversion

Edit
Mainstream develops transportable pyrolysis reactors to convert lignocellulosic waste biomass and mixed waste to pyrolysis bio-oil. Moreover, we sell small 1 kg/hr benchtop pyrolysis systems to universities and laboratories engaged in biomass research. We also operate a 1 ton/day pilot reactor at our Rockledge, Florida facility. The pilot-scale reactor was developed for government applications, providing on-site renewable energy generation to improve energy security.
Edit
Most small-scale reactors operate by batch processing or handle minimal amounts of feedstock material. As a result, designing, building, and commissioning a custom bench-scale process can be highly time-consuming and costly. Mainstream has eliminated the inherent risk by developing a pyrolysis test platform and is offering the industry a standard system capable of process optimization, bio-oil upgrading, and bio-oil collection testing and research.
Mainstream’s continuous, bench-scale pyrolysis unit provides a reliable test platform for pyrolysis research. The biomass feedstock optimizes the fluidized bed reactor yielding bio-oil of 65%. This system ultimately provides the researcher the ultimate control and flexibility of process parameters (e.g., temperature, residence time) and bio-oil separation and collection.
