u00b0 f gellation temperature of the gel at that point the temperature was held within 2 u00b0 f of the hold temperature of 140 u00b0 f by injecting steam into the jacket of the kettle next referring to the drawing figure the liquid product was then pumped from the kettle 10 by a positive displacement pump waukesha equipped with a speed controller set at 19 75 hertz to a manifold 14 having eight outlets each equipped with a solenoid operated valve 16 each valve leading to a long tube 18 open at its discharge end in the illustrated system there are eight tubes 18 connected in parallel to the pump each having an id of about 0 44 inch and a length of about 12 feet the manifold 14 and tubes 18 are of a strong rigid material such as stainless steel or polytetrafluoroethylene teflon the tubes 18 all extend along most of their lengths through a cooling manifold 20 containing a cooling medium the illustrated manifold 20 contained water maintained at a temperature of about 40 u00b0 and circulated through the manifold at a rate of about four gallons per minute as shown in the drawing figure the discharge ends of tubes 18 are aligned horizontally and a rotary cutter 22 is located just beyond those ends so as to be in position to cut the ropes emerging from all of the tubes 18 the valves 16 controlling the inlets to the tubes 18 are controlled by a controller 24 such that each tube 18 is filled in sequence for about 12 5 seconds followed by a static residence time of product in each tube for about 87 seconds as each tube is filled the statically formed gel in that.
