Sweet potato cellaring device

Abstract

The invention provides a sweet potato cellaring device. The sweet potato cellaring device is composed of a cellar, a solar panel, a battery pack, a ventilating fan, an air inlet, an air outlet, a gate, a hose, a temperature sensor and a controller; the sweet potato cellaring device is characterized in that the space area of the cellar is set according to a user's needs, a board is placed ten centimeters above the floor in the storage area of sweet potatoes, a storage area is arranged on the board, and a layer of white carbon is placed on the ground surface under the board; the air outlet is connected to the hose to extend to the deepest part of the cellar, the ventilating fan is installed at the joint of the hose, and the solar panel is installed in the open field to receive the solar energy and supply power to storage batteries; the controller is connected to the temperature sensor, the ventilating fan and the gate and is powered by the battery pack; the air inlet and the air outlet are formed in a cellar entrance. After the sweet potatoes are cellared and stored, the controller works all the year round, the temperature sensor sends indoor temperature to the controller in real time, and the controller commands the ventilating fan and the gate to open or close normally according to a program set by a single chip microcomputer.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a sweet potato storage device. Background technique [0002] Sweet potato has high starch content, and the young leaves can be used as vegetables, food, wine and starch raw materials; sweet potatoes can also be called "sweet potatoes", "sweet potatoes", "sweet potatoes", "sweet potatoes", " "Sweet Potatoes", "Sweet Potatoes". [0003] Scientific sweet potato storage requires the following key points: 1. Temperature: The optimum temperature for sweet potato storage is 10°C-14°C, within this range, the respiration is not much different. When the temperature rises to 20°C, respiration is enhanced, more nutrients are consumed, bran heart is caused, and the occurrence of black spot and soft rot is accelerated. Temperatures below 9°C are susceptible to chilling damage, causing the inside of the potato pieces to turn brown and black, resulting in a hard core, which cannot be boiled, and is ...

AI Technical Summary

Problems solved by technology

[0004] As is known to the storage of sweet potatoes, our ancestors or predecessors all used the cellar to store the new sweet potato season from winter to the second year. The usual storage method is to first spread a layer of rice stalk or straw in the cellar, and then seal the cellar; The ancient storage method has lasted for thousands of years, and has made extraordinary contributions to human food storage; of course, due to the characteristics of sweet potatoes, combined with artificial storage methods, the predecessors cannot control the humidity, temperature and ventilation of the cellar, which will lead to a certain proportion of sweet potatoes. rot, there is a shortcoming of low storage efficiency; today, technicians and science and technology departments have not proposed a better storage method for sweet potatoes
