PiGo Food Processing Systems develops complete processing solutions for fruit and vegetables. The production covers Easy Freeze & Easy Freeze Spyro, stainless steel fluidized bed and spiral freezers, cooling/pasteurization spiral solution, Easy Cook Vacuum cooking plants and deaeration plants, as preparation for freezing and producing fruit cubes.
A spiral conveyor and a freezing system, which provides a well-distributed airflow, basically compose the Easy Freeze Spyro freezer.
Regarding the technical design, the drum is without lateral openings in order to improve the air guidance and to minimize the possibility to accumulate dirt.
In order to obtain a quick freezing process, Easy Freeze Spyro is designed for the high-speed circulation (4-10 m/sec) of cold air in contact with the product on the whole length of the spiral conveyor. In this way, products suffer a very low weight loss (two times less than with vertical air-flow). Hitting the incoming product with the coldest air, the product is therefore immediately “crusted” reducing the snow formation. The increase of temperature of air that passes through the product is very low, thus avoiding the increase in humidity content.
Cold air passes directly from the evaporator to the product, not through fan motors, thus providing the coldest air and the most uniform air distribution (otherwise there are losses of 2°C). The lateral aprons to guide the airflow on the opposite side of the evaporators are of easy access design (such as opening or sliding doors).
There is the possibility to have bi-directional airflow and speed on the product adjusting the by-pass and fans.
Finally, the high speed of air in Easy Freeze Spyro increases a good exchange on the surface of the product, the speed of cold penetration, and the quality of the freezing process, and long running time with very low frost forming.
