Hoyer Rollo® IM: Extended Freezing Time for Innovative Multi-Layer Products
23 August 2007 15:31
Tetra Pak has launched the Hoyer Rollo IM, a high capacity moulding machine for automatic, continuous production of ice cream, sherbet, or fruit-juice stick novelties with up to 20 lanes of 56 mm wide stick products.
Now the huge potential for multi-flavour, multi-layer ice cream products has been released and only imagination limits the possibilities to create consumer interest through innovative stick novelties.
The Hoyer Rollo IM has been developed specifically to meet the growing market for flexible and reliable equipment that can handle a wide range of new, commercially attractive product. ideas.
EFFICIENT LAYOUT AND HIGH CAPACITY PRODUCTION
The easy to set-up, slim in-line design of the Hoyer Rollo IM allows for a production room layout with additional equipment such as filling and back suction stations, and multiple lines with easy access for manual add-ins.
The compact equipment is ideal for high capacity production of multi-layer products made from water ice and/or ice cream mix combinations. Between extraction and lay-off, the stick novelties also may be coated with chocolate, and chocolate-dipped products may be coated with dry ingredients.
The Hoyer Rollo IM provides steady performance at high capacity and guaranteed high total-line yield of more than 97.5%. Tetra Pak offers two models: up to 15,000 sticks/hour or 30,000 sticks/hour. Actual capacity will depend on factors such as the number of lanes, product volume and recipe, as well as the capacity of the wrapping and packing line. Together with the Hoyer Flowrap MW F2 wrapping machine, the Hoyer Rollo IM can achieve very high efficiency.
COOLER ICE CREAM QUICKLY CHANGED
The Hoyer Rollo IM's PLC controlled programme, with pre-set product recipes, secures quick change-over and start-up times. All in-line functions, including drive and the filling equipment, are controlled via the PLC from one central control panel.
The stainless steel PLC cabinet is mounted on the side of the brine tank and has a touch screen for recipe set-up and information. All components and cables are CE approved.
The fully welded, stainless steel brine tank is designed for products which need extended freezing time, such as thick water ice sticks. The brine distribution system is equipped with nozzle plates that provide even freezing and even shell thickness on split ice, at maximized freezing capacity.
Re-circulated warm water is used for defrost at extraction, to minimise the risk of contaminating the product with brine and to eliminate mould corrosion - as no warm brine is in contact with the stainless steel moulds. The moulds are also cleaned with water during every cycle, leaving no flavour mix residue in the moulds – a feature ideal for multi layer products.
"New, exciting multi-layered ice cream products can create new sales trends, strengthen brand loyalty and win market shares, as well as offering the possibility of higher yield," says Kurt Kristensen, Product Manager for Hoyer Rollo IM. "Extended freezing time for moulded stick novelties at high capacity brings creativity to ice cream production."
Main production stages involve:
- Filling of ice cream into the moulds
- Insertions of wooden sticks into the ice cream
- Freezing of the bars in a cold brine bath at -40 °C (-40 °F)
- Defrosting of a thin outer layer of the bars with warm water spray at +15-25°C (+59-77 °F)
- Extraction of the frozen bars from the moulds
- Lay-off for packing
