Puffed Rice (Murmura) & Recovery & Value Added
Puffs rice
Enter your rice quantity, recovery rate and the price per kg of murmura to get the puffed output, the expansion ratio, and the value of the puffed rice.
Puff your rice batch
Next: price your murmura against the ₹6,800 batch value and your raw-rice + fuel cost; a higher recovery % directly lifts your margin.
Recovery depends on rice variety, parboiling, moisture and the puffing method (sand-roasting vs gun-puffing) — track your own real recovery to price accurately.

Turn cheap rice into a premium snack
Puffing is one of the simplest, oldest forms of value addition: heat treated rice until each grain bursts into light, crisp murmura. You recover most of the weight — around 80–90% — but the puffed product fetches a far higher price per kilogram than the plain rice it came from. That spread is the whole point, and it's what makes murmura, mamra and kurmura a steady cottage and small-industry trade.
This tool gives the puffed output, the expansion ratio, the recovery percentage and the value of your batch in 8 currencies, so you can see the weight you'll get and what it's worth. Use it to price your murmura and plan batches, then pair it with the Value Addition Profit and Rice Milling Recovery tools to work out the full margin from paddy to finished snack.

Frequently Asked Questions
What is puffed rice recovery?+
Recovery is the share of your input rice that comes out as puffed rice (murmura/murmure) by weight. Puffing drives off moisture and expands the grain, so you recover roughly 80–90% of the rice weight — but the puffed product sells for far more per kg. The tool multiplies your rice by the recovery rate to give the puffed output.
How is puffed rice made?+
Treated rice — usually parboiled and conditioned with a little salt and moisture — is heated rapidly in hot sand or a puffing machine until the trapped moisture flashes to steam and expands each grain. The result is light, crisp murmura. Quality depends on the rice variety, conditioning and puffing temperature.
Why is the puffed output less than the rice in?+
Puffing removes moisture and a little fine breakage, so the puffed weight is lower than the rice that went in — typically 80–90%. The grains expand in volume even as they lose weight, which is why a small bag of murmura feels so light. The recovery rate captures this weight loss.
How is the value calculated?+
Value = puffed output × the price per kg of murmura. Because puffed rice sells for much more per kg than the plain rice, the output value usually far exceeds the cost of the rice — that gap is the value addition. The tool shows the puffed weight, the expansion ratio and the value together in your chosen currency.
What is the expansion ratio?+
Here it's the puffed weight relative to the rice input — for example 0.85 means 85% recovery. Some people use volume-based expansion (how many times the grain swells), which is much larger; this tool works on weight recovery, the figure that matters for costing and selling by the kilogram.
Is puffing a good value-addition business?+
It can be — murmura is a staple snack and bhel/chaat ingredient with steady demand, low equipment cost and a healthy margin over plain rice. Profit depends on your rice cost, fuel, labour and the selling price. Use this tool with the Value Addition Profit calculator to see the full margin before scaling up.
Which rice works best for puffing?+
Short and medium-grain parboiled rice puffs best; the parboiling gelatinises the starch so the grain expands cleanly. Old rice and the right moisture conditioning improve puffing. Variety, age and conditioning all affect both the recovery rate and the crispness, so test your local rice and use its actual recovery in the tool.
Can I use this for mamra or kurmura too?+
Yes — mamra, kurmura, murmure and pori are regional names for puffed rice, and the same recovery logic applies. Enter your rice quantity, the recovery rate you actually achieve, and the local selling price per kg to estimate output and value in whatever currency you trade in.
Does it work in any currency?+
Yes — choose from 8 currencies and enter the local price per kg of puffed rice; the value is computed in that currency. The recovery and output are weight-based and currency-independent, so only the value figure changes with your currency and price.
Are the figures exact?+
The output and value are exact for the recovery rate and price you enter, but real recovery varies with rice variety, moisture, puffing method and breakage. Measure your own recovery over a few batches and use that rate, and update the price to current market rates, so the value reflects your actual operation.
