Blanched mushroom sorter: accurate grading into 4 sizes with several processes running at once
A multi-purpose design for the end of the blanching line
After blanching and cooling, mushrooms have to be separated by size so that each size goes to the right route: large mushrooms for slicing, medium and small sizes for whole canned mushrooms or for barrelling. The Nano Machine blanched mushroom sorter does this continuously and accurately, grading the mushrooms into 4 different sizes.
What sets this machine apart is that it can run several processes at once: you can barrel one or more sizes directly on one side of the machine, while the other sizes are inspected on the opposite side and sent to the slicer. This flexibility lets producers prepare several different products at the same time, without stopping the line or extra handling.
How does a mushroom sorter work?
In the processing line, the mushroom sorter is placed after the spiral mushroom cooler and receives the blanched, cooled mushrooms.
Feeding blanched mushrooms
The cooled mushrooms enter the sorter inlet in a continuous flow.
Sorting by size
The sorting mechanism divides the mushrooms into 4 sizes based on cap diameter.
Separate routes
Each size is guided to its own outlet.
Barrelling or inspection
One or more sizes are barrelled on one side, while the other sizes are inspected on the opposite side.
To the slicer
Mushrooms selected for cutting go straight to the blanched mushroom slicer.
Mushroom sorter price
The price of a mushroom sorter depends on the capacity you need, the number and range of sizes, the layout of the outlets and any customisation. Nano Machine sells this machine directly, with no intermediaries, and our engineers review your capacity and line layout before you buy. To slice the graded mushrooms, see the blanched mushroom slicer and the other mushroom processing machinery.

Blanched mushroom sorter technical specifications
The Nano Machine blanched mushroom sorter is built with a capacity of 1200 kg per hour, a power consumption of 4.5 kW, dimensions of 720 × 170 × 330 cm and a weight of about 1100 kg. The technical specifications, including the size range and the number of outlets, can be customised to suit your production line.
Grading into 4 sizes: the basis of product quality and pricing
In the market for canned and processed mushrooms, size is one of the main criteria for quality and pricing. A product of uniform size looks better in the can or package and can be sold in different grades at different prices.
By grading mushrooms accurately into 4 sizes, the Nano Machine mushroom sorter lets you choose the best processing route for each size: uniform mushrooms for whole canned mushrooms, larger sizes for slicing and surplus sizes for barrelling and storage. This precise separation directly increases the added value of every kilogram of mushrooms.
Simultaneous barrelling and inspection: a highly flexible production line
In many factories, part of the blanched mushrooms is stored in barrels for sale or for use in later seasons, while another part goes straight into the canning line. The Nano Machine blanched mushroom sorter is designed to support both routes at the same time, with no need to stop the line or move product by hand.
- Accurate grading of blanched mushrooms into 4 different sizes
- Barrelling of one or more sizes on one side of the machine
- Inspection and slicing of the other sizes on the opposite side
- High speed and shorter process times
- Less waste and higher line productivity

What to check before buying a mushroom sorter
Before buying a mushroom sorter, it is worth reviewing a few key points with our engineers so that the machine fits your line exactly. First, establish the real capacity of your blanching and cooling line, so the sorter neither becomes a bottleneck nor is larger than you need. Second, define the size ranges your target market wants, because product grading has a direct effect on the selling price.
Third, plan the route of each size after sorting in advance: which sizes are barrelled, which go to the slicer and which go straight into cans. Finally, take into account the floor space and where the inspection operators will stand. Nano Machine engineers review all of these points before making a technical proposal, so the mushroom sorter delivers the highest productivity for your line with the fewest changes to the layout.
Applications of the mushroom sorter in the food industry
The Nano Machine blanched mushroom sorter is used in plants that prepare mushrooms for different uses after blanching, including:
Canned mushroom factories
Grading mushrooms to produce whole canned mushrooms in different grades and sending suitable sizes to the slicer.
Mushroom barrelling and storage units
Sorting and barrelling blanched mushrooms for wholesale or for use in low-yield seasons.
Ready meals and frozen food production
Supplying mushrooms of uniform size for ready meals, salads, pizza and frozen products.
Secondary processing industries
Separating mushrooms outside the size standard for by-products such as mushroom powder and food extracts.
Why the Nano Machine mushroom sorter?
Nano Machine builds complete mushroom processing lines and has designed its mushroom sorter to work seamlessly with the mushroom cooking blancher, the spiral cooler and the blanched mushroom slicer. This integration ensures an even product flow through the whole line, and the experience behind it comes from projects in Iran and exports to Turkey and the Persian Gulf countries.
Summary for production managers
With accurate grading into 4 sizes, simultaneous barrelling and inspection, a capacity of 1200 kg per hour and an operator-friendly design, the Nano Machine blanched mushroom sorter helps you get the most value from every kilogram of mushrooms and makes your production line more flexible and faster.
To buy a mushroom sorter, share your line capacity and the sizes you need with the Nano Machine team, and you will receive a technical proposal and a factory-direct price.
