Put in Sichuan peppercorns, cryopreservation method, sun exposure, and add white wine.

1. The first is how to put Sichuan peppercorns. Wrap the Sichuan peppercorns into small bags with light and transparent cloth and put them into the rice vat. The Sichuan peppercorns contain natural antioxidants and will emit a special fragrance, so the Sichuan peppercorns have Insect repellent effect.

2. The next method is to freeze and preserve it. We can use this method when the rice is not seriously infested with worms. Put all the rice in the freezer of the refrigerator, let the rice freeze for more than one day, then take it out, and finally pick out the frozen insects.

3. The simplest method is sun exposure. The bugs cannot withstand the high temperature of the sun and will crawl out on their own. Then wait for the bugs to crawl out, sift through it with a sieve, and finally put the sifted rice into bags.

4. The last way to put white wine is to put the worm-infested rice into a clean container, then put half a bottle of white wine without closing the lid, and then insert it into the rice, making sure the bottle mouth is slightly high. Prevent wine from spilling on rice noodles, and seal the container to prevent rice from getting insects.
