Starfrost has completed the first installation of its new Glacier system, which combines the latest spiral freezer technology and unique low volume ammonia refrigeration plant.
The company supplied a dual-purpose freeze/chill Glacier system to one of the UK’s largest producers of pork for a brand new product range.
The project features a dual-purpose spiral freezer/chiller with 24-inch wide stainless steel product belt and 30 tiers around a single rotating drum - the system is capable of processing up to 2,000kg/hr of uncooked sausages.
Starfrost managing director Neil Winney says: “Raw sausages have delicate skins that are notoriously difficult to freeze, often being prone to dryness and cracking. Our Glacier spiral features accurate temperature control and a unique airflow specially designed for delicate products. This will enhance product quality compared to a conventional spiral system.”
Starfrost’s Glacier spiral system has a simple design to maximise uptime and requires minimal ongoing maintenance. The spiral unit has an all stainless steel structure, fully welded stainless steel floor system and a fully accessible product zone for ease of cleaning.
A fully automated CIP (Clean in Place) system was also installed, which utilises high pressure, low volume water and chemical dosing for effective system cleaning.
Located externally within a weatherproof housing, the sausage manufacturer’s Glacier refrigeration package has a 215kW capacity and operates with very low volume natural refrigerant ammonia. This is said to result in high operating efficiency, with zero environmental impact in terms of ozone depletion and global warming.
Neil Winney adds: “Not only does the refrigeration plant run with a low charge of ammonia, the operating principle is simpler and easier to maintain than conventional pumped systems.”
The Glacier spiral and its accompanying refrigeration plant both have a compact design and small footprint. The weatherproof housing for the refrigeration package means that no internal plant room is required. Each Glacier refrigeration plant is factory assembled and only requires simple connection on site, whilst the spiral is delivered in modules for ease of assembly.
As a spiral system, Glacier is suitable for freezing or chilling food items such as pizza, ready meals, poultry, meat and fish, as well as pastry products and desserts. Each Glacier package is designed, manufactured and installed to meet individual cooling requirements, with dual-purpose freeze/chill operation available.
Glacier features a range of spiral systems and associated refrigeration packages, with cooling capacities from 75kW to 450kW. Available with a range of belt sizes and tier heights, Glacier can be designed to process from 500kg/hr, to over 6,000kg/hr.
