Abstract

The invention discloses a method for synchronously removing the shell and peel of a Chinese chestnut through microwaves. The method comprises the following steps: the shell of the Chinese chestnut is cut, the Chinese chestnut is subjected to microwave processing for the first time, the Chinese chestnut is cooled after the microwave processing for the first time, then, the Chinese chestnut is subjected to microwave processing for the second time, the shell and the peel of the Chinese chestnut are removed after the microwave processing for the second time, and therefore the kernel of the Chinese chestnut is obtained. According to the method for synchronously removing the shell and peel of the Chinese chestnut through the microwaves, the microwaves are used for instantaneous intermittent heating with a high power, as a result, the kernel of the Chinese chestnut shrinks due to dehydration and is separated from the shell and the peel, and the phenomenon that the kernel of the Chinese chestnut is cooked and exploded due to an excessively quick temperature rise in the one-time heating process can be well avoided; meanwhile, the hot Chinese chestnut is cooled for a short time, as a result, water in the shell of the Chinese chestnut is evaporated, brittleness is further improved, and original color and luster, a special flavor and nutrition of the kernel of the Chinese chestnut are guaranteed to the maximum.

Description

technical field [0001] The invention relates to the field of deep processing of agricultural products, in particular to a method for synchronously shelling and peeling chestnuts by microwave. Background technique [0002] Chestnut (scientific name: Castanea mollissima), also known as chestnut, belongs to the nut plant of Fagaceae (Fagaceae). It is native to China and is known as "hardcore crop" and "king of dried fruits". It is suitable for raw food, fried food, steaming, cooking, etc. Chestnuts are delicious, unique in flavor and rich in nutrition. Traditional Chinese medicine believes that chestnuts have the effects of nourishing the stomach and strengthening the spleen, nourishing the kidney and strengthening tendons, promoting blood circulation and stopping bleeding, and reducing swelling. Clinically, chestnut can also be used to treat nausea, diarrhea, weak waist and legs, vomiting blood, blood in the stool, gold sores and other diseases. [0003] However, due to the...
