Small grain dryer

Abstract

The invention discloses a small grain dryer comprising a feed hopper. The feed hopper is connected to the inlet of a drying rolling drum; the outlet of the drying rolling drum is connected to the inlet of a cooling rolling drum, the outlet of the cooling rolling drum is connected to a discharge hopper, and the air inlet of the drying rolling drum is connected to a hot air outlet of a straw combustion furnace; the drying rolling drum comprises an outer heat insulation drum, the outer heat insulation drum is provided with an inner rolling drum inside, asymmetric copy boards are distributed on the wall of the inner rolling drum circumferentially, the inner rolling drum is provided with hot air flowing holes, and the inner rolling drum and the outer heat insulation drum are sealed through a sealing sleeve; the outer heat insulation drum is fixed, and the inner rolling drum is capable of rotating; the inner rolling drum is provided with a temperature sensor, a humidity sensor and a microprocessor inside, the temperature sensor and the humidity sensor transmit the acquired data to the microprocessor, and the microprocessor transmits the data to an upper computer; the drying rolling drum, the cooling rolling drum and the straw combustion furnace are arranged on a trailer. By the aid of the small grain dryer, the problems of rural straw combustion and grain drying can be solved.

Description

technical field [0001] The invention relates to a drying machine, in particular to a small grain drying machine. Background technique [0002] my country is a big country of grain production and consumption. Due to the low level of science and technology in my country's grain production, especially the grain production process of small and medium-sized farmers, the quantity and quality of grain production are low. According to statistics, the loss of my country's grain in the process of threshing, drying, storage, and transportation after harvest is as high as 15%, far exceeding the 5% standard set by the Food and Agriculture Organization of the United Nations. Among these losses, up to 5% of the grain is lost due to mildew and germination due to the humid climate, wet valleys that are too late to dry or fail to reach safe moisture. If calculated on the basis of an annual output of 500 million tons of grain, it is equivalent to a loss of 15 million yuan. tons of grain. The...
