Spiral mushroom cooler: stopping the cooking process right after blanching
Mushrooms are still hot when they leave the blancher, and if they are not cooled immediately they keep cooking: they soften, darken and lose quality in the following stages of sorting, slicing and filling. The Nano Machine spiral mushroom cooler is placed directly after the blancher and stops the cooking process instantly with a cold-water shock.
How does a spiral mushroom cooler work?
Infeed from the blancher
Blanched mushrooms enter the machine's tank directly from the blancher outlet.
Immersion in cold water
The mushrooms are immersed in cold water and the cold shock stops the cooking; this is known as immersion cooling.
Spiral movement
The machine's screw moves the mushrooms gently and evenly along the tank, so they are all cooled to the same degree.
Discharge to the next stage
The cooled mushrooms are conveyed continuously to the sorter or the slicer.
Advantages of the Nano Machine spiral mushroom cooler
- Fast, even cooling with the immersion method and spiral design
- Natural mushroom colour preserved by stopping cooking instantly
- Less physical damage to the mushrooms thanks to the gentle screw movement
- Continuous operation in step with the blancher and sorter in the processing line
- Helps extend the shelf life of the finished product
Applications of the spiral mushroom cooler
This machine is used in any mushroom processing line where mushrooms are blanched, including canned mushroom production lines, blanched mushroom production and the preparation of mushrooms for ready meals. In the Nano Machine mushroom processing line, the spiral cooler sits between the mushroom cooking blancher and the sorter or blanched mushroom slicer.
Spiral mushroom cooler vs. spiral vegetable cooler
Both machines work on the same principle, but the spiral mushroom cooler is designed for the size and characteristics of mushrooms and the capacity of a mushroom processing line, while the vegetable cooler is designed for the products of a vegetable cooking line.
Spiral mushroom cooler price
The price of this machine depends on the capacity you need and how it connects to the blancher and the rest of the line. For an up-to-date price, fill in the quote request form or contact the Nano Machine team.
If you are setting up a mushroom processing line, plan the spiral cooler together with the mushroom cooking blancher and the sorter, so the capacities of the machines match.
