Problems solved by technology

Since most of the main drying equipment currently used are mixed-flow or down-flow dryers, the temperature of the medium is high, the drying energy consumption is high, the cost is high, the crack rate of rice increases, and the rate of polished rice is low. After drying, the rice processing is affected to a certain extent. Food quality and economic value

Abstract

The invention relates to a full-natural automatic-control granary ventilation and drying device, which is characterized in that electric energy is provided by a wind-driven power generator, a storage battery pack and an inverter, a wind-driven air compressor generates compressed air and the compressed air is further boosted through a GBM gas booster and is used as high-pressure air for granary ventilation; an auxiliary heat source is arranged in a ventilation pipeline to increase the temperature of the high-pressure air in the ventilation pipeline; a single-chip microcomputer instructs a pneumatic valve to open or close the ventilation pipeline according to the upper limit value and the lower limit value of data transmitted by a plurality of temperature-sensitive and humidity-sensitive probes arranged in a granary; and fine holes on air outlet columns which are connected with each other and are arranged in the granary evenly exhaust the high-pressure air to achieve the goal of ventilating and drying grains in the granary. The full-natural automatic-control granary ventilation and drying device has the advantages that the stored rice can be dewatered gently and evenly, no dead zone exists, the operation is intelligently conducted, the labor is saved, the conventional energy is saved, the drying and the storage are environmental-friendly and pollution-free and the requirements on environmental protection are satisfied.

Description

technical field [0001] The invention relates to the technical field of granary ventilation and drying, in particular to an automatic control granary ventilation and drying device utilizing all natural energy. Background technique [0002] With the progress of society, the processing, storage and fresh-keeping of food are paid more and more attention. Especially as the most edible grain variety——rice, how to realize the green and dry storage of rice has been paid more and more attention by grain administrative departments at all levels. Since most of the main drying equipment currently used are mixed-flow or down-flow dryers, the temperature of the medium is high, the drying energy consumption is high, the cost is high, the crack rate of rice increases, and the rate of polished rice is low. After drying, the rice processing is affected to a certain extent. Edible quality and economic value. [0003] Using natural energy to ventilate and dry stored grain has the advantages o...
