Device using vacuum to rapidly regulate particulate material dampening

Abstract

The invention discloses a device for quickly adjusting the water impingement of granular materials by using vacuum. The air shutoff device is communicated with the lower end of the shell of the grain spray watering mechanism, the upper end of the shell of the grain spraying water mechanism is communicated with the lower end of the grain inlet section, and the lower end of the hollow silo passes through at least one high airtight The air shutoff device is communicated with the upper end of the grain outlet section; the body wall of the hollow silo is provided with an evacuation pipe. The grain spray watering mechanism includes a casing, a feeder and a water mist nozzle, and a swirl plate is arranged on the outer surface of the feeder, and a secondary swirl plate is arranged on the inner wall of the casing below the feeder. Make the grain evenly rotate and fall, and improve the water effect. The invention has the advantages of simple structure, low energy consumption, good water infiltration effect and high working efficiency, wide application range and good economic and social benefits.

Description

1. Technical field: [0001] The invention relates to a watering device for grain processing, in particular to a device for rapidly adjusting the watering of granular materials by using vacuum. 2. Background technology: [0002] China is a large agricultural country, and the output of grain is huge. If it is not stored well, it will deteriorate. Therefore, it is necessary to reduce its moisture content before storage, which will cause a loss of tons when the grain is out of the warehouse, resulting in economic losses; Water needs to be applied before further processing to increase the flexibility of the grain and reduce the breakage rate during processing. At the same time, it can improve the milling effect, improve the quality of flour and the flour extraction rate, so the grain needs to be watered before processing after leaving the warehouse. Currently The watering method commonly used at home and abroad is to spray water on the grain, and the equipment usually used is a sp...

Problems solved by technology

[0002] China is a large agricultural country, and the output of grain is huge. If it is not stored well, it will deteriorate. Therefore, it is necessary to reduce its moisture content before storage, which will cause a loss of tons when the grain is out of the warehouse, resulting in economic losses; Water needs to be applied before further processing to increase the flexibility of the grain and reduce the breakage rate during processing. At the same time, it can improve the milling effect, improve the quality of flour and the flour extraction rate, so the grain needs to be watered before processing after leaving the warehouse. Currently The watering method commonly used at home and abroad is to spray water on the grain, and the equipment usually used is a spraying water machine, which contains a collection chamber with an inlet and outlet, and a collection chamber located below the feed inlet. There is a leveling umbrella on the wall of the material cavity, and a nozzle is arranged under the leveling umbrella. When in use, the grain flows down from the feeding port through the leveling umbrella, and the nozzle sprays mist water to water the grain. This method and equipment are carried out under normal pressure, and the speed of water mist soaking into the grain is slow. Generally, it takes 20-30 hours for the grain to achieve the effect of complete infiltration. The time is long, the efficiency is low, and the infiltration effect is not ideal. , and some also need to stir the grain to make the water even, which increases the processing procedure and production cost
