Novel high-efficient heated air circulation type cereal drying machine

Abstract

The invention discloses a novel high-efficient heated air circulation type cereal drying machine. The novel high-efficient heated air circulation type cereal drying machine comprises a machine frame, a dust exhaust pipe, a top rail, a feed pipe, an equal divider, a bin, a baking bin and a base, wherein the dust exhaust pipe, the top rail, the feed pipe, the equal divider, the bin, the baking bin and the base are sequentially mounted on the machine frame from top to bottom; a lifting machine and a discharge pipe are mounted on the side surface of the machine frame; a flow divider is arranged at an outlet of the lifting machine; cereals are controlled by the flow divider to enter the feed pipe or the discharge pipe; a food grain discharge auger and a moisture meter are mounted in the base; the equal divider is an unpowered automatic-rotation type conical food sprinkling equal divider; the baking bin is divided into an air inlet corner box layer and an air outlet corner box layer up and down; a calorifier is a variable frequency motor; and the magnitude of the air outlet quantity is controlled according to the water ratio measured by the moisture meter. The novel high-efficient heated air circulation type cereal drying machine disclosed by the invention adopts whole sealing design, is simple in structure and reliable in mechanism, the occurrence of material plugging situations can be effectively avoided, and the feed rate of the cereals can be increased; the equal divider is improved, so that the crushing rate is low, the consumption of energy resources is low, the machine is convenient to operate and in maintenance operation, the baking efficiency is high, and the novel high-efficient heated air circulation type cereal drying machine has favorable economic benefits.

Description

technical field [0001] The invention relates to a novel high-efficiency hot air circulation grain dryer, which belongs to the field of grain dryers. Background technique [0002] Grain is a necessity of human life. All countries attach great importance to grain production and storage. However, before the grain is collected and put into the warehouse, most of the grain is not dried in time due to weather or other reasons, and it becomes moldy and deteriorates, which not only affects the quality of grain but also poses a threat to human health potential hazard. Therefore, before storing grain, it is necessary to give grain precipitation to reach safe moisture before storing. At present, the following two methods are mainly used for drying grain. One is to use the method of sun exposure, and the other is to use a large dryer to dry the grain. The former is limited by the weather and occupies a relatively large area, requiring open ground. Grain spreading, the latter is the dr...

Problems solved by technology

At present, the following two methods are mainly used for drying grain. One is to use the method of sun exposure, and the other is to use a large dryer to dry the grain. The former is limited by the weather and occupies a relatively large area, requiring open ground. Grain spreading, the latter is the drying method used in the production of large granaries at present. In the grain dryers of the prior art, the circulation mode of feeding and discharging materials generally adopts a hoist and an upper auger arranged on the top of the dryer and a The lower auger at the bottom of the dryer is realized. This method can easily cause material blockage, and the movement of the auger will easily cause grain damage, increase the rate of grain breakage, high energy consumption and high failure rate; There is no maintenance and removal hole in the material layer, which will cause great inconvenience to maintenance once the material is blocked
