Process hot air circulating device for tobacco charging machine and control method for device

Abstract

The invention discloses a process hot air circulating device for a tobacco charging machine and a control method for the device. The hot air circulating passage of the device consists of a drum, a front drum chamber, a rear drum chamber and a conduit communicated with the front drum chamber and the rear drum chamber; the hot air circulating conduit is provided with an air supply pipe communicatedwith a radiator, the air supply pipe is provided with an air supply port with an electric angle actuator, an axial flow fan is arranged on the hot air circulating conduit and positioned between the front drum chamber and the air supply pipe, and the hot air circulating conduit is also provided with a temperature sensor; and the radiator is also connected with the electric angle actuator. The front drum chamber and the rear drum chamber are also communicated with an air pipe, and a dehumidifying fan is arranged on the air pipe. The air supply pipe is provided with a temperature sensor. The radiator is positioned below the drum. Compared with the circulating hot air control mode of the prior art, the device has the advantages of effectively preventing the radiator from scaling, improving the heat exchange efficiency of the radiator and adjusting the temperature of the process circulating hot air more effectively and quickly.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a hot air circulation device for a tobacco feeder process and a control method thereof. Background technique [0002] The feeding process is an important part of the cigarette shred process. In this process, the tobacco leaves not only need to be heated, humidified, etc., but also need to add a certain proportion of feed liquid quantitatively, and a series of changes in the chemical composition of the tobacco will occur, which will ultimately affect the quality of the tobacco. The intrinsic quality and flavor of cigarettes. Among them, the control of the temperature of the process hot air is very important. In the traditional design of the feeder, part or all of the process circulating hot air must pass through the radiator. This process hot air control method mainly has the following disadvantages: 1. The hot air containing sugar material passes through t...

AI Technical Summary

Problems solved by technology

This process hot air control method mainly has the following disadvantages: 1. The hot air containing sugar material passes through the radiator and scales, resulting in low thermal efficiency of the radiator and short service life of the radiator; 2. When the temperature of the hot air is low, it is necessary to use steam To make it reach the temperature required by the process, which in turn affects the moisture control accuracy of the product

The effect of hot air is not good; the outlet moisture is difficult to control; 3. The drum warms up for a long time, and sometimes it does not even meet the requirements of the process hot air temperature; 4. The temperature adjustment feedback speed in the drum is slow
