a drying machine

Abstract

The invention discloses a grain drying machine, which belongs to the field of liquor brewing equipment, and comprises a conveying device and an air supply device, wherein an air outlet of the air supply device is arrange above the conveying device; the conveying device is provided with a grain drying shovel-turning mechanism, the grain drying shovel-turning mechanism comprises a rotating shaft and shovel-turning wings circumferentially distributed on the rotating shaft, and the end part of each shovel-turning wing is provided with a shovel plate. An effect that a link plate for distillers grain spreading and drying has no material leakage and is cleaned conveniently and thoroughly is achieved, and the grain drying requirements on sanitation and safety of traditional manual distillers grain spreading and drying are satisfied; and cooling is more thorough, and the discharging temperature is more uniform, thereby achieving an effect of keeping the original state of distillers grain materials undamaged in the process of shovel-turning for distillers grain spreading and drying.

Description

technical field [0001] The invention relates to the field of liquor brewing equipment, in particular to a drying machine. Background technique [0002] The grain drying machine is a drying equipment for distiller grains used in the brewing process of the liquor industry. At present, the distiller's grains are mostly transported by porous chain conveyors. During the conveying process, air is supplied from the air box at the bottom of the chain plate through the fan, and a certain air pressure is formed in the air box, and the air passes through the holes of the conveying chain plate by pressure. And pass through the layer of distiller's grains, so that the distillers' grains are cooled. During the conveying process, a rotating stirring roller is installed on the top surface of the chain plate to disperse the distiller grains while the distiller grains are cooling. This bad airing machine has the following problems in use: [0003] 1. Leakage of distiller's grains from the ...

AI Technical Summary

Problems solved by technology

[0003] 1. Leakage of distiller's grains from the holes on the chain plate, resulting in the number of bacteria falling from the distiller's grains exceeding the standard;

[0004] 2. The distiller's grains contain a large amount of steamed and gelatinized grains, and the gelatinized grains are easy to block the holes of the chain plate. Once the holes are blocked, this part of the holes cannot be ventilated, and the cooling of the distiller's grains above will be seriously affected, resulting in uneven discharge temperature at the end. Cannot meet the technical requirements of drying temperature;

[0005] 3. The distiller's grains in the chain plate holes cannot be cleaned thoroughly, and harmful bacteria grow in large numbers, which seriously affects the quality of liquor;

[0006] 4. When stirring, the material is mainly broken up by a small shaft rotating at a high speed. Distiller's grains contain a large amount of cooked and gelatinized grain starch, which will further closely bond the starch during the breaking up process, causing serious damage to the state of distiller's grains. Seriously affect the post-fermentation of distiller's grains and the quality of original wine;

[0007] 5. Stirring can only break up large pieces of material, but cannot turn over the material. The bottom material close to the chain plate is easy to agglomerate and harden, which does not meet the technical requirements of distiller's lees loosening for liquor brewing
