Historical Evolution of the Ice Pop: From Brine to the Disruptive Era
The trajectory of ice pop industrialization evolved from artisanal freezing in manual molds to highly automated systems. Discover the milestones that shaped this market:
1. The Industrial Revolution: Rotary, Inversion, and Oval Tracks (1950 – 1980)
- 1950 | Hoyer (Denmark): Launched the HOYER ROLLO, the first industrial rotary machine with a continuous circular table (10,000 to 30,000 popsicles/h).
- 1958 | FMC Corporation (USA): Patented the VITALINE, pioneering the linear system with a vertical mold inversion loop for continuous automatic sanitation.
- 1960s | Gram Equipment (Denmark): Introduced the GRAM RIA line, establishing the global high-capacity standard for multinationals (>40,000 popsicles/h).
- 1970s | Glacier Industries (USA): Introduced continuous extrusion with wire-cut stainless steel and forced-air freezing tunnel.
- 1980s | LAIEF (Italy): Created the 'oval track' rotary machine (technology expanded by Teknoice in the RO line), eliminating the central blind spot and facilitating multi-filling dosing.
2. Mold Standardization and Semi-Industrial Automation (1990 – 2010)
- Commercial Mold Standardization: Adoption of standardized stainless steel molds (8, 16, 22, or 28 cavities) paired with stick aligners.
- Built-in Defrost Tanks: Integration of a compact 'water bath' within the frame to release popsicles in seconds.
- High-Performance Thermal Fluids: Replacement of traditional brine with food-grade high-efficiency fluids (such as Finamac's FINAFLUID), ensuring freezing in under 10 to 12 minutes at -40 °C without equipment corrosion.
Finamac's Visionary Tradition: The Invention of the PopCircle
In 2012, Finamac gathered PhD engineers and leading research institutes to develop ultra-fast direct cold freezing (research that eventually birthed the future AUTOPOP and SPEEDYPOP). During this process, the team identified an urgent demand: the market needed an industrial rotary machine accessible not only to multinationals, but also to expanding medium and large producers.
Thus, PopCircle was born: a semi-automatic rotary machine operating with standardized commercial molds up to 28 cavities, featuring an integrated defrost system. Unlike linear machines, the molds never need to leave the equipment during operation!
Smart Production Flow
- Multi-Layer Dosing: Automatic dispensers mounted over the rotary table precisely apply liquid mixes, chunk-filled mixtures, and creamy fillings (such as caramel or syrup) without pausing production.
- Streamlined Stick Insertion: The operator uses the Automatic Stick Aligner to load sticks into the metal Extractor and places the assembly directly into the newly dosed mold.
- Smart Localized Defrosting: A submerged metal chamber inside the tank rises to enclose the mold, drains cold fluid, injects warm fluid to release the popsicles, and drains it back before submerging again. All in a matter of seconds!
- Rapid Extraction and Packaging: The operator removes the extractor filled with finished popsicles and mounts it directly onto the automatic wrapper's feeder.
Exclusive PopCircle Advantages
- Innovative FINAFLUID Fluid: The same fluid handles both freezing and defrosting. It is non-corrosive unlike brine, non-flammable, approved for food contact, and maintains excelente fluidity down to -40 °C.
- Advanced Electronic Intelligence: An electronic central unit manages operations from dosing to defrosting, controlling freezing speed and temperature with millimeter precision.
- Reinforced Fiberglass Tank: Fully rounded corners for seamless sanitation, optimized structure for targeted jetting, and drastically reduced fluid volume. Costs up to 4 times less and requires 1/3 of the fluid needed by conventional stainless steel tanks.
- Mold Savings: The localized defrost system saves around 5 molds on the turntable compared to industrial 'waterfall' systems. PopCircle delivers high performance with only 30 molds (840 cavities)!
- Automatic Level Control: Integrated surge tank regulates optimum fluid levels, ensuring perfect product finish and freezing.
- Zero Splash Contamination: Heavy-duty engineering plastic table with precision slots. Prevents thermal fluid from splashing inside products, overcoming a common flaw of traditional linear machines.
- Lean and Ergonomic Operation: Semi-automatic workflow requiring minimal manual intervention, dramatically lowering labor costs.
- Effortless Sanitation: Allows easy mold removal for individual or automated hot washing. Main tank engineered for complete draining, ensuring fast and hassle-free cleaning.
