AI Technical Summary

Technical Problem

In existing tobacco sheet re-drying equipment, the intensity of the functional hot air flow passing through the tobacco sheet material is uneven, resulting in poor consistency of tobacco sheet moisture and uneven product quality.

Method used

The device employs a sheet drying system, which includes a drying chamber, a heat pump drying assembly, an air distribution plate, a conveying assembly, an air distribution mechanism, and a hot air collection duct. The hot air velocity is controlled by the air collection assembly and a vibrating motor, and the vibrating motor flattens the sheet, thus achieving a uniform distribution of the hot air field.

Benefits of technology

It improves the consistency of moisture content in tobacco sheet materials, enhances product quality, and makes the tobacco sheets spread more evenly during the drying process.

Abstract

When tobacco flakes need to be re-dried in the tobacco flake processing process, the tobacco flakes can be conveyed into a drying box through a conveying assembly, then a heat pump drying assembly is operated to generate hot air, the hot air is conveyed to the lower portion of the drying box, and then the hot air penetrates through an air uniformizing plate to reach the conveying assembly. The tobacco flakes on the conveying assembly are redried and dried, then redried hot air enters the hot air gathering pipeline through all the air collecting assemblies and the air inlet, meanwhile, the hot air is filtered through the air filter net, and the situation that the broken tobacco flakes enter the hot air gathering pipeline is avoided; then hot air is guided back into the heat pump drying assembly through a hot air gathering pipeline to be circularly dried, meanwhile, the difference of the hot air speeds in all the air collecting assemblies can be reduced by controlling the hot air speeds in all the air collecting assemblies, meanwhile, a vibration motor can be operated, the vibration motor drives the conveying assembly to vibrate, and the tobacco flakes on the conveying assembly are flattened.
