Green and efficient fresh-keeping storehouse for sweet potatoes and fresh-keeping storage method thereof

Abstract

The invention discloses a green and efficient fresh-keeping storehouse for sweet potatoes. The green and efficient fresh-keeping storehouse comprises a storehouse body where sweet potato piles are placed, wherein the storehouse body is of a semi-underground structure; a heat preservation mechanism and a ventilation mechanism are arranged on the storehouse body, wherein the heat preservation mechanism comprises a soil covering layer laid at the top end of the outer side of the storehouse body and a heat preservation layer arranged at the top end of the interior of the storehouse body; and the ventilation mechanism comprises a fresh air inlet pipeline arranged on the side portion of the storage warehouse body in a penetrating mode and an exhaust pipeline arranged at the top end of the storage warehouse body in a penetrating mode. According to the green and efficient fresh-keeping storehouse for the sweet potatoes with the structure, the storage environment condition is improved, the storage tolerance of sweet potatoes is improved through the storage steps of variety storage resistance identification, harvesting, grading, pre-storage callus treatment, storehouse body pre-disinfection,sweet potato warehousing and storage, sweet potato disinfection and the like, sweet potato pest and disease damage during storage is reduced, and chemical agents are not used, so that the eating safety is improved.

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...
