Re: Dispensing Bulk Honey
If one keeps honey warm enuf to use a heated tank, like a bottling tank, as a dispenser of honey in a store, eventually the honey will darken and the flavor may be effected. The stores I sell to dispense honey out of the 5 gallon plastic tote in which I deliver the honey to them. a plastic gate is used. Maybe like the one you mentioned.
One outlet has a tank on a heat pad, set really low. But, they go thru 3 or 4 totes per month. so the honey isn't in the tank very long. This tank has the spout or gate built in. I don't know anything else about it.
