Talk:Cornelius keg

Moved text
I moved the following here from the article since it clearly reads as a user comment: —MJBurrage • TALK  • 21:48, 18 February 2007 (UTC)


 * According to a page on the Quality Wine and Ale Supply web site, there is a currently (as of 10/27/2006) a shortage of Cornelius kegs. The page states that the price of stainless steel is very high presently and that both used and new Cornelius kegs are "in short supply."  It goes on to note that both Pepsi and Coke have abandoned the Cornelius keg in favor of "aseptic bags."  This is followed by the assertion that all of Pepsi's used Cornelius kegs have been sold to the Chinese.  (Confirmation of this assertion would be nice in order to ensure that the statement is not being made by an ambitious seller of kegs who would benefit from a perceived shortage.)  If that is the case, then, as the Quality Wine page asserts, there could very well be a shortage in the market for used Cornelius kegs.

 * Three years on, and indeed there is no shortage of Corny kegs. I'm a home brewer in Australia and have 8 kegs, and my supplier gets good quantities from the USA, many of them etched "Pepsi" and from locations such as Idaho and Kansas. You did well to remove that section. Due to their popularity in home brewing, new Cornelius kegs are once again being made, and whilst four or five times the price of reconditioned kegs, some brewers will pay this price for a brand new item. I'll add a paragraph if I can find some reliable references. --MichaelGG (talk) 03:29, 30 September 2010 (UTC)

incorrect details in page.
i don't have references, i just worked at a 711 store and know how these systems work i worked for a year back in the 80s and 15 years from 1995 to 2009

i feel that article is wrong

first of all, it is called POST MIX and not PREMIX PREMIX is what you bought in a can at the store


 * Comment/clarification:
 * The article is using the correct term there, as it is describing the tanks’ use for dispensation of pre-mix (that is, beverages that have already been diluted to serving strength and fully carbonated before delivery). However, it is misleading in that it neglects to acknowledge their use in post-mix systems, which, prior to the adoption of bag-in-box, were the most common applications for Corney tanks. (You later said that the the article identifies Bag-in-Box as pre-mix. If so, someone must have fixed it, because I don't believe it does now.)
 * As you pointed out, in a post-mix system, the Corney tank (or a BiB) holds syrup concentrate which is then mixed at the faucet with tap water (after passing the water through an inline chiller and carbonator).
 * Premix systems at the time were primarily intended for environments in which an external water supply might be unavailable (such as a mobile food truck or a temporary beverage booth at a picnic or other special event) or for small environments where "no-fuss" dispensing was more important than volume (such as an office break room). Equipment expense probably also played a role, as I noticed in the ’90s that newly-manufactured pre-mix dispensing fountains were quite a bit cheaper than new post-mix fountains. That may have been related to shifting demands, but I suspect it was due to the presence of an inline carbonator in the latter.
 * (By the way, as with post-mix, pre-mix tanks can also be connected in series. As the article appears to have been originally composed from the perspective of one re-purposing them for dispensing homebrewed beer, it is not surprising that that feature is not mentioned, as most homebrewers who make batches larger than the capacity of a Corney keg would either employ brewery kegs or swap out Corneys when empty rather than chaining them together.)
 * The soft-drink distribution industry standardised on the versatile Cornelius tank [in the ’60s & ’70s, maybe? I don’t even know what they used previously] because its dual suitability for both pre- and post-mix meant the need to store, transport, clean and maintain only one type of container for all their fountain customers.
 * Eventually, the durability and convenience of Bag-in-Box improved, and, by the mid-'90s, BiB had replaced Corney tanks for most post-mix applications. For pre-mix fountains, though, I believe the tanks still remain the most widely used solution. However, bulk pre-mix seems to have largely disappeared, as many environments that formerly used it have either switched to post-mix BiB or to individual bottles. (I used to purchase pre-mix soft drinks for our system at home, but it was actually more expensive in bulk Corneys than in 1- or 2-litre bottles, so I suspect that even larger users may have found that the convenience of bottles outweighed any savings there might have been from continuing to handle pre-mix tanks.)
 * I don’t have hard facts to back up any of this; I never worked in the industry. This is merely my own interpretation of what I have observed over the years. So, do some research before making edits based on what I have said. —Starling2001 (talk) 23:35, 26 December 2018 (UTC)

The Syrup inside the tank is the same exact syrup in the bag in the box.

it is the same conentrated syrup that is mixed in the store with tap water and co2 to make the finished product.

the bag in the box makes it easier to change boxes. and there are no heavy tanks to lug around. the downside of bag in the box is that you can only hook up two bag in the boxes to one soda valve

the tanks are harder to change out. they are bulkier. the tanks can be hooked in series. you can have a lot more tanks hooked up to the same line. you can have up to 9 or 10 or so tanks connected. the tanks are under pressure.

the difference is, is that bag int he box is pumped out like a vacuum and the tanks are pushed out, the co2 pushes the syrup from its negative connector to its positive one and its just like batteries, and you can connect several in series.

when i was working at 711 in the 80s we had tanks

i know for a fact that the syrup sold back in the 80s was concentrated just like it was now in bag in the box because we used the same brix kit. once in a while you had to check the briix to make sure it was the correct ratio. (4.75 to 1 on regular and 5.25 to 1 on diet) we had the same water supply and co2 supply back then.

the only difference now a days is most places have filtered water,

if you are selling a lot of soda, then the tanks are recommended, because each one makes 24 gallons of soda.

we used to have tanks for slurpees. back in 95. and we had to depressurize the tank, and had to pour concentrate into the tank, and close it, and the co2 system would repressurize the system
 * Syrup from BiB? Or from jugs? Either way, what a mess! I'm guessing that the shop had just been slow to modernise the equipment. (Perhaps the owners were holding off on it in anticipation of a major store-wide remodeling that kept getting postponed or were planning to sell the operation to someone else. —Starling2001 (talk) 23:45, 26 December 2018 (UTC)

if the containers contained premade soda and was not concentrated, then each tank would only hold 15 super big gulps. that just right there tells you that the article is flawed

you would be changing that tank every 12 hours, if it was not concentrated.

back in the 1980s 7-evelven would train its managers / field consultants ( district managers ) on how to operate a brix kit, to verify that the syrup was being mixed in the store to the correct ratio

now that 711 is using bag in the box and belives its equipment is more reliable, they no longer train anybody store level to check ratios. this is something that 7-11 maintenance does now

just like slurpee machines. now 711 maintenance cleans half the slurpee machine once a year, instead of having store personal do it

this page says that the tanks and the bag in the box are both "post mix"
