Ice Cream Machine / June 22, 2018 / Millie Torrez
Soft serve is a classic sweet treat that has been enjoyed since the 1940s. As anyone who has ever stopped by a Mister Softee can attest to, although it is definitely ice cream, it’s a bit different from what you might buy in a grocery store. There are several competing claims about who first invented soft serve–Tom Carvel, the Dairy Queen family and even Margaret Thatcher are all names that come up. But wherever it came from, here’s how it works:
Horizon Pump. The best way to tell the difference is to open up the machine. The horizon pump is easily distinguishable by its use of 2 sets of tubes per barrel (used as hopper below the machine in large full standing models) as well as the circular face plates that create a semicircle shape with the tubes. The horizon pump has a more intricate assembly in which it has a variety of O rings instead of plastic pieces. Since the horizon pump uses a more complicated system with rubber pieces, then it is much more complicated to disassemble, clean, and reassemble. Since it is more complicated to take apart and put back together you usually need some training (typically 3 session) from a Taylor company technician. The extensive use of O rings and other rubber parts makes the machine more reliable and less likely to mess up compared to the simplified pump (although both pumps have a very small percentage of mistakes).
