All-metal mixed-flow grain dryer

Abstract

The present invention discloses an all-metal mixed-flow grain dryer which comprises a shell which is made of alloy steel. The middle of the shell is provided with a hot air chamber connected to a hot air inlet, the top of the shell is provided with a storage barn, both sides of the storage barn are provided with exhaust gas discharge outlets, the hot air chamber is connected to a drying zone of a hollow cavity, retractable laminates are arranged inside the drying zone, a cooling zone is arranged below the drying zone, the bottom of the cooling zone is provided with evenly distributed cold air inlets, the hot air inlet is connected to an oil furnace which provides heat source. The all-metal mixed-flow food dryer is convenient to conduct series production, has series combined segments with equal lengths and heights, not only can generate down-flow, but also can generate counterflow and crossflow, has little damage to grains, and strong applicability for materials, can dry small granules of seeds, such as rapeseed, millet, sesame, etc., ensures the drying mass of grains, and can immediately realize cooling after drying is completed, and achieve the storage requirements.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an all-metal mixed-flow grain dryer. Background technique [0002] With the continuous development of modern society, people's living standards have also been improved day by day, especially for farmers who face the loess and their backs to the sky, they have indeed undergone great changes in farming. With various farming tools With the emergence of the invention, people's farming operations have become much easier. It can save people a lot of manpower, material resources and financial resources, make farming all enter the modernization, have more time for other activities, and improve people's physical and mental cultivation. [0003] As we all know, the water content of fresh grains is far greater than the safe water stored. If they are not air-dried in time, or in bad weather, the grains are prone to mold and deterioration, so they need to be dried. The method ...

Problems solved by technology

[0003] As we all know, the water content of fresh grains is far greater than the safe water stored. If they are not air-dried in time, or in bad weather, the grains are prone to mold and deterioration, so they need to be dried. The method of drying is to spread the grains on the ground , Evaporate water through direct sunlight, which is the most traditional operation method, but this method is inefficient, requires a lot of manpower, and is quite laborious. Although there are some dryers, the flexibility of use is not good, and the air-drying effect Not good, the heat energy utilization rate is low, the hot air effect is not good, etc., the fresh grain cannot be air-dried very effectively, resulting in the moisture of the grain not meeting the storage requirements, and the heat is greatly consumed, the energy saving is poor, and there are deficiencies that cannot be met. social development needs
