Spiral or tunnel: which one do I need?

A spiral freezer packs a long freezing path into a small footprint; a continuous tunnel suits straight-line production and larger, flat products. We recommend the layout after looking at your product, output and plant.

Is it a standard product?

No. Each IQF system is designed around your product, volume and plant, which keeps it simpler and less expensive than an oversized standard line.

What products is it for?

Industrial bakery products, seafood, breaded and prepared products, berries and vegetables: anything that must come out loose and keep its quality.

Does it require construction?

No. It is containerized and integrates into your plant with no construction.

What is the IQF Blast Freezer?

IQF stands for Individual Quick Freezing: each piece freezes separately, so product comes out loose and can be portioned, weighed and packed without thawing the whole batch. The speed forms small ice crystals, so thawed product keeps its moisture, texture and weight. Traditional IQF lines are large, permanent investments. ZGROUP designs simpler, containerized IQF systems, as a spiral freezer or a continuous tunnel, for companies that need IQF quality without the big CapEx: industrial bakeries, seafood processors, breaded and prepared products. Each project is designed around your product, volume and plant.
