Sweet potato storage device and storage method

Abstract

The invention provides a sweet potato storage device and storage method. A storage device body comprises walls and a ceiling, the walls are fixedly connected with the ceiling, damp-proof layers are arranged on the inner walls of the walls, at the bottoms of the walls and on the inner wall of the ceiling, the walls are provided with an entrance, loopholes and a temperature and humidity controller,and an ozone generator is arranged at the joint of the ceiling and the walls. The storage method includes the steps: 1 selecting healthy sweet potatoes; 2 soaking the sweet potatoes in lime water; 3 air-drying the soaked sweet potatoes; 4 disinfecting the storage device; 5 storing the sweet potatoes; 6 disinfecting the sweet potatoes; 7 monitoring temperature and humidity; 8 performing daily management; 9 discharging the sweet potatoes. The temperature and the humidity in the storage device can be strictly controlled within the optimal temperature and humidity range of sweet potato storage. Moreover, ventilation effects are good, the disease resistance of the sweet potatoes can be improved, morbidity and rotting of the sweet potatoes are decreased, and the device is reasonable in design and worthy of vigorous promotion.

Description

technical field [0001] The invention relates to the field of storage of agricultural products, in particular to a sweet potato storage device and a storage method thereof.
