Editing KFC (section)

===Equipment===
KFC initially used stove-top covered [[cooking pot]]s to fry its chicken.<ref name=shelton>{{cite news|last=Coomes|first=Steve|title=Winston Shelton: The Colonel's Corporal|newspaper=[[Louisville Magazine]]|date=July 17, 2012|url=https://archive.louisville.com/content/winston-shelton-colonels-corporal-food-dining|access-date=October 1, 2013|archive-date=April 11, 2021|archive-url=https://web.archive.org/web/20210411065952/https://archive.louisville.com/content/winston-shelton-colonels-corporal-food-dining|url-status=live}}</ref> In the 1960s, the officially recommended model was the L S Hartzog developed "KFC 20-Head Cooker", a large device that cost $16,000.<ref name=winston>{{cite web|title=History |url=http://www.winstonind.com/kfc/history/ |publisher=Winston Industries |access-date=October 1, 2013 |url-status=dead |archive-url=https://web.archive.org/web/20131004213804/http://www.winstonind.com/kfc/history/ |archive-date=October 4, 2013 }}</ref> The Hartzog model had no oil filtration system, meaning that filtering had to be done manually, and the pressure fryers occasionally exploded often harming employees.<ref name=shelton /> In 1969, inventor and engineer [[Winston L. Shelton]] developed the "Collectramatic" pressurized fryer to overcome the problems KFC faced in quickly frying chicken to meet growing customer demand. The Collectramatic used precision time and temperature controls and self-filtered the cooking oil – all while meeting Colonel Sanders' high standards.<ref name=shelton /> Fred Jeffries, then vice president of purchasing at KFC, claimed that the invention helped fuel the company's rapid expansion and success:

<blockquote>There's no way it (KFC) could have grown as it did without the Collectramatic. Stores were doing about $200,000 a year in sales on average with the pots...but they could never have done the $900,000 a year it became without Win's fryer. He (Shelton) helped set the stage for that with true engineering thinking.<ref name=shelton /></blockquote>

Although a number of franchisees bought the Collectramatic, which had the support of Colonel Sanders from 1970 onwards, John Y. Brown Jr. had given tacit approval to franchisees to exclusively use the older L S Hartzog fryer, saying "Though those old pots were damn dangerous, at least we knew they worked! I was mostly afraid these new fryers would break down in the middle of business."<ref name=shelton /> Brown warned franchisees that they were in violation of their contract if they used the Collectramatic.<ref name=shelton /> Brown held his ground on the issue until he learned that his father, [[John Y. Brown Sr.]], who owned multiple KFC franchises, was successfully using the Collectramatic in every franchise he owned.<ref name=shelton /> The issue was eventually resolved after Heublein purchased KFC, acquired Hartzog and nullified the contract.<ref name=winston /> The Collectramatic has been an approved pressure fryer for KFC from 1972 onwards.<ref name=winston />

From 2013 onwards, KFC has been transitioning from using Collectramatic cookers to pressure fryers produced by [[Henny Penny (manufacturer)|Henny Penny]], which supplies KFC with various equipment.<ref>{{cite web|url=https://www.hennypenny.com/press-release/henny-penny-wins-kfc-equipment-supplier-of-the-year-award-2/|title=Henny Penny Wins KFC Equipment Supplier of the Year Award|work=Henny Penny |access-date=July 16, 2019|archive-date=July 16, 2019|archive-url=https://web.archive.org/web/20190716011408/https://www.hennypenny.com/press-release/henny-penny-wins-kfc-equipment-supplier-of-the-year-award-2/|url-status=live}}</ref> The 'Velocity' series of pressure fryers includes increased load capacity, automatic oil filtration and increased oil longevity.
