Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a chestnut kernel sterilization device. Background Technology

[0002] Chestnut kernels are a processed food made from chestnuts through shelling. The flesh is slightly yellow and can be eaten directly or used in cooking such as soups and porridge. Traditional Chinese medicine believes that chestnut kernels have functions such as strengthening the waist and kidneys, invigorating the spleen, stopping diarrhea, preventing cancer, and promoting blood circulation and stopping bleeding. Modern medicine believes that the unsaturated fatty acids contained in chestnuts have conditioning effects for patients with hypertension and coronary heart disease. Modern processing uses an assembly line for peeling, sorting, quality inspection, blanching, sterilization, and quick-freezing to produce ready-to-eat chestnut kernels, which can be stored for 18 months.
