Abstract

The invention discloses a green and high-efficiency fresh-keeping store for sweet potatoes, which comprises a storage body on which piles of potatoes are placed. The storage body is a semi-underground structure. The covering soil layer on the outer top and the insulation layer arranged on the inner top of the storage body, the ventilation mechanism includes a fresh air duct pierced at the side of the storage body and an exhaust duct pierced at the top of the storage body. The present invention adopts the sweet potato green high-efficiency fresh-keeping store with the above structure, which improves the storage environment conditions, and adopts the storability-harvesting-grading-pre-storage callus-pre-disinfection of the storage body-sweet potato warehousing-storage-sweet potato Storage steps such as disinfection improve the storability of sweet potatoes, reduce the occurrence of sweet potato diseases and insect pests during storage, do not use chemical agents, and improve food safety.

Description

technical field [0001] The invention relates to a sweet potato green storage technology, in particular to a sweet potato green high-efficiency fresh-keeping store and a fresh-keeping storage method thereof. Background technique [0002] Sweet potato is the seventh largest food crop in the world and the fourth most important food crop in my country. It has high nutritional value and is deeply loved by consumers. The seasonality of sweet potato production is strong, which forms a contradiction with the annual supply demand of the market. At the same time, after the sweet potatoes are harvested and stored for a period of time, the starch in the potato pieces is converted into sugar, which can improve the flavor and taste of the sweet potatoes. Therefore, it is of great significance to study the storage and preservation of sweet potato. [0003] Due to the large size, high water content, tender tissue and thin skin of sweet potato pieces, they are easily rotted due to mechanic...
