Reagent Mixer arrives at 20X24 in Ashland

Our neighbors at New55 are 20x24 Studio which is an amazing thing because together we have concentrated all US instant film development under one roof.  Ted McLelland runs their engineering and contributes to New55, and one of his key areas of responsibility involves the making of reagents - also known as processing developer, goo, jelly or paste - for both black and white and color products.  Yesterday, one of 20X24's large units arrived in Ashland and was quickly set up by the experienced ex-Polaroid riggers who still move large things around New England.

In this series, Ted inspects the newly-arrived Big Mixer that uses heat, pressure, vacuum, large stirring vanes and lots of valves and gages interconnected in such a way as to produce about 30 litres of reagent a day.  That translates into enough reagent to fill a few thousand pods. This mixer was installed and run in Connecticut for the past several years, but now is under the same roof as the Pod Machine, which it feeds.
