Method for controlling circulating fan of bulk curing barn for improving tobacco smoking quality

Abstract

The invention discloses a method for controlling a circulating fan of a bulk curing barn for improving tobacco smoking quality, which comprises the following steps of: setting time and frequency by sections for a frequency converter of the fan of the curing barn, using 5Hz as an adjusting unit, wherein before the tobacco is cured to 38 DEG C, the frequency of the frequency converter is not more than 35Hz, the rotating speed of the circulating fan is not more than 1050r / min, and when the tobacco is cured to 42 DEG C-54 DEG C, the frequency of the frequency converter is 50Hz, the rotating speedof the circulating fan is kept at 1480r / min, after the tobacco is cured to 54 DEG C, the frequency of the frequency converter is 30-45Hz, the rotating speed of the circulating fan is 900-1200r / min,the power consumption is obviously reduced after the frequency converter of the bulk curing barn is reformed, the electric energy is saved by about 30%, the wind speed is soft, the tobacco is dehydrated, becomes yellow and is dried step by step, a large amount of aroma substances are deposited and accumulated, the chemical components are coordinated, and the industrial use value of the tobacco isimproved.

Description

technical field [0001] The invention belongs to the technical field of curing barn control equipment, and in particular relates to a method for controlling a circulation fan in a dense barn for improving the smoking quality of tobacco leaves. Background technique [0002] my country is a big tobacco producing country, with the planting area and total output ranking first in the world. Since the mid-1980s, my country has promoted standardized production of tobacco, and the quality of tobacco leaves has been greatly improved. Prominent problems in production have seriously affected my country's raw material export earnings and the improvement of cigarette product quality. [0003] In recent years, with the popularization and application of ordinary monomer-intensive coal-fired barns, my country's overall level in the field of crop roasting has been significantly improved, and it has also contributed to the expansion of crop planting area, the gradual formation and specializati...

Problems solved by technology

However, with the implementation of the modern agricultural strategy, people's requirements for "green and low-carbon, energy-saving and emission-reducing, labor-saving and consumption-saving" intensive barns have been further increased, and the shortcomings of ordinary intensive barns have become increasingly prominent

The heating system and temperature and humidity control system of the existing intensive barn are all controlled manually. This control method is labor-intensive and the control effect is difficult to grasp; the error is large, which easily leads to uneven distribution of the temperature and humidity field, which in turn makes the Uncontrollable quality of baked products and high energy consumption
