Embodiment

[0151] like figure 1 The grain vacuum dryer shown includes drying chamber (1), heat exchange device (2), heat pipe (3), lifting device (4), discharge valve (8), wet material bin (9), vacuum unit (10), heating device (11), air duct (13), dry feed bin (20), support (21), heat circulation pump (23).

[0152] The dry bin (1), the wet bin (9), and the bin body (26) of the dry bin (20) are made of 6mm metal plates.

[0153] 1. The appearance of the drying bin (1) is a cylindrical shape with both ends closed, and the lower end of the drying bin (1) is conical.

[0154] 2. The outside of the bin body (26) of the drying bin (1) is wrapped with an insulating layer to keep warm.

[0155] The wet hopper (9) has a material inlet and a material outlet; the dry hopper (20) has a material inlet and a material outlet.

[0156] The upper end of the drying bin (1) has a feed port (6).

[0157] 1. A discharge valve (5) is installed on the feed port (6) at the upper end of the drying chamber (...

Abstract

The invention provides a vacuum dryer for cereals. The vacuum dryer comprises a drying bin, a heat exchange device, a support, a lifting device, a vacuum unit, a heating device, an air guide pipe, a heat conducting pipe, a hot recycle pump, a wet material bin, a dry material bin and a discharge valve, wherein the discharge valve is mounted at a feeding port in the upper end of the drying bin and connected with the wet material bin; an exhaust port in the upper end of the drying bin is connected onto the vacuum unit through the air guide pipe; the heat exchange device is mounted in a body of the drying bin; the lifting device is mounted in the central position in the drying bin; the heat conducting pipe is used for connecting the heating device and the heat exchange device and conveying a heat-conducting medium; when the dryer is in drying work, the inside of the drying bin is in a sealed closed state. The vacuum dryer for the cereals is simple in structure, small in equipment size, lowin manufacturing cost and good in heat preservation effect; the heat exchange device in the drying bin adopts three-dimensional heat exchange and heat conduction, the heat conversion efficiency is high, the loss is low, the heat conduction and exchange speed is increased, and the drying speed of the cereals is increased.

Description

technical field [0001] The invention relates to a dryer, in particular to a grain vacuum dryer. Background technique [0002] At present, the grain harvester is not equipped with a synchronous dryer. The grain harvester can only harvest grain, and cannot dry the harvested grain at the same time. The moisture content of the harvested grains is high. If the weather is cloudy and the wet grains cannot be dried in time, it is easy to cause mildew of the grains and affect the quality of the grains. [0003] The vehicle-mounted dryer equipped on the grain harvester that has now has a large volume, and its production process is complicated and the production cost is high. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and design a grain vacuum dryer. The grain vacuum dryer has simple structure, small size, low production cost and good heat preservation effect. After the grain harve...
