Tunnel freezer–IQF is a simple structure, highly efficient freezing equipment. There are stainless steel belt tunnel freezer and mesh belt tunnel freezer.
After tunnel freezer, we can use glazing machine, let products enter 0 degrees ice water, because products less then-18 degrees now, the ice water will be attached to the surface of the products.
And we let products immediately enter hardening machine, it is a simple tunnel freezer in fact, use the hardening machine to freeze the attached ice water, let it become-18 degrees ice and connected with the products as a whole.
The return mesh belt of our hardening freezer is outside the library body, so that the ice on the mesh belt will melt by itself in the air and will not form ice particles. We have rich experience in this field.
