Food production lines
A freezer is one stage. YONGXING supplies the stages around it as one connected line — designed, built and installed by the same factory, so the interfaces between machines are our responsibility, not yours.
How a line is put together
Washing
Soil, sand and surface contamination come off first, so every later stage handles clean product.
Grading
Pieces are sorted to one size, so the freezer can be set correctly for the whole batch.
Blanching
A short heat treatment stops enzyme activity and holds colour and texture into frozen storage.
Dewatering
Surface water is shaken and drained off, so it does not become ice load in the freezer.
IQF freezing
The freezing stage, matched to the product: fluidized bed for small pieces, spiral or impingement for formed products.
Glazing
For seafood lines, an even ice glaze protects the frozen product through cold storage.
Packing
Graded, frozen product goes to packing in flow, at the grade it was frozen to.
Not every line needs every stage. The line is specified stage by stage against your product, target output and layout.
