Automatic controller used for forced ventilation in storage period of potatoes

Abstract

The invention discloses an automatic controller used for forced ventilation in the storage period of potatoes. The automatic controller comprises a temperature sensor, a central processing module, a display module, a clock module, a fan control module and a fan. An output end of the temperature sensor is electrically connected to an input end of the central processing module, an output end of the central processing module is connected to an input end of the fan control module, the fan control module is connected with the fan, the display module is electrically connected with the central processing module, and the clock module is electrically connected to the central processing module. Therefore, the fan can be intelligently controlled according to temperature changes of storage environment, ventilation and temperature reducing effects inside potato piles are increased, storage time of potatoes is prolonged, storage loss of the potatoes is reduced, and labor intensity of managers is also reduced.

Description

technical field [0001] The invention relates to the field of forced ventilation storage facilities for agricultural products, in particular to an automatic control device for forced ventilation during potato storage. Background technique [0002] Potato is a fresh agricultural product that requires a long storage period. In order to reduce storage loss, maintain edible quality, and extend storage period, potatoes need to be properly ventilated during storage. Scientific and reasonable ventilation can not only adjust the temperature and humidity inside the storage and carbon dioxide content, but also to avoid condensation on the surface of potato skins. At present, some potato storages in the northern part of my country are equipped with forced ventilation systems, and the switch of the fan is mainly controlled by the switch manually. The outside temperature is low at night and in the morning, which is suitable for forced ventilation. The management personnel need to turn on...

AI Technical Summary

Problems solved by technology

The outside temperature at night and in the morning is low, so it is suitable for forced ventilation. The management personnel need to turn on the fan, and when the outside temperature rises, they need to turn off the fan. The temperature and humidity in the warehouse cannot be effectively regulated, especially the temperature and humidity inside the potato pile

Moreover, during the ventilation period, due to the large temperature fluctuations in the warehouse, condensation water is easily generated on the surface of potato skins, which eventually leads to short storage time and large storage losses, which seriously affects the economic interests of potato storage personnel.
