La solution

This project is the first domestic pre-proofed frozen dough project, wihich presents great challenges. Square Technology and Intralox of theUnited States work together to perfectly use the direct drive technology in this project.

Our engineering and application team tailor-made, installed and commiissioned Quadruple -drum DDS spiral freezer forproofing and one singledrum DDS spiral freezer for freezing withfreezing capacity up to 50,000pcs for croissant dough.

The project features an 817mm wide stainless-steel conveyor belt, with total length of 2000m around five rotating drum of 74 tieers in total.

The freshly dough enter into spiral proofer at +25 degrees Celsius, andexit with temp. of 35 degrees Celsius. Then enter into spiral freezer exitwith temp. of -18 degrees Celsius finally.

The diameter of all the spiral drum reaches 5m. The temperature of spiralproofer is controlled at 33°C+1 and the humidity is controlled at 80%6+1.5%.

The spiralfreezerdesign can not only deal with the pre-proofed produucts and can also handle the unproofed products. It can flexiblyadjust the outfeed temperature and to fulfill customer’s diversified demands.
