How to peel walnut kernels?

Walnuts are a common food in real life. Walnuts are rich in nutrients, various minerals, fats, proteins, etc. Regular consumption has many benefits for the human body and brain. However, it is very difficult to peel fresh walnuts, which can easily affect their convenience of consumption. There are many ways to peel them. You can use a machine to peel them, or you can soak the walnuts in hot water. As the temperature of the hot water increases, the walnut skin will be easier to remove.

(1) Pharmacy peeling :

After the fruits are harvested, they can be soaked in 200~300 times diluted ethephon for 30 seconds and then piled in a cool place or indoors with a thickness of 50~60 cm. Cover them with straw mats or weeds and keep the temperature at around 30°C. The green skin can be removed after 2~3 days of piling. The peeled fruits can be rinsed with clean water to remove debris and then dried in the sun.

(2) Retting and peeling :

After the fruits are harvested, they should be transported to a cool place outdoors or indoors in time, and should not be exposed to the sun. They should then be piled into piles about 50 cm thick. If a layer of breathable covering is added on the fruit pile, the temperature inside the pile can be increased, promoting the ripening of the fruit and speeding up the peeling process. The general composting time is 3-5 days. When the green fruit peel is separated from the shell or cracked by more than 60%, it can be knocked with a wooden stick to peel it off. During the fermentation process, pay attention to the changes in the walnuts. Do not let the green skin turn black or rot, which will reduce the quality of the walnuts and lose their commercial value.

(3) Mechanical peeling :

Mechanical peeling saves labor and time, has high efficiency, and has a clean appearance. The peeling and cleaning process does not require ripening, additives, or bleaching. The walnut peeling machine has a green peeling net rate of 88% and a mechanical damage rate of only 1%. It can peel about 1,200 kilograms of walnuts per hour. The cleaning and peeling can be completed in one go and is easy to operate. It is worthy of promotion and use by large walnut growers.
