Clean energy inner circulation intensive baking room baking system

Abstract

The invention discloses a clean-energy internal-circulation bulk curing barn curing system. The system comprises a heat supply subsystem, a dehumidifying subsystem, a control subsystem and a tobacco loading chamber and is characterized in that every two of the heat supply subsystem, the dehumidifying subsystem and the tobacco loading chamber are connected with each other through air pipelines, heating air flow circulates in the heat supply subsystem, the dehumidifying subsystem and the tobacco loading chamber and is not discharged, monitoring sensors and electric equipment in the heat supply subsystem, the dehumidifying subsystem and the tobacco loading chamber are electrically connected with the control subsystem, the monitoring sensors acquire state signals, corresponding control signalsare output through the embedded algorithm program and control program of the inner microcontroller of the control subsystem to control the electric equipment to work coordinately according to a preset curing process curve to achieve internal-circulation curing. The clean-energy internal-circulation bulk curing barn curing system has the advantages that clean-energy heat supply is adopted, consumption of non-renewable resources and pollutant emission can be reduced, the air-internal-circulation condensate dehumidifying manner is used, and heat loss and tobacco fragrance loss can be reduced.

Description

technical field [0001] The invention belongs to a tobacco leaf curing system, in particular to a tobacco leaf curing system using clean energy as a heat source and adopting air internal circulation. Background technique [0002] Since entering the 21st century, with the rapid development of my country's modern tobacco agriculture, every link of tobacco production is running efficiently. Reducing labor, reducing costs and increasing efficiency in tobacco leaf production are the urgent needs and main tasks of tobacco leaf production. Tobacco leaf curing is the last and most important link that determines the quality and yield of flue-cured tobacco. Although the development and promotion of intensive curing rooms and curing processes have promoted my country's great progress in tobacco leaf curing, However, there are still many problems in practical applications: In the heat supply of existing barns, coal combustion still occupies a large proportion.

Problems solved by technology

Tobacco leaf curing is the last and most important link that determines the quality and yield of flue-cured tobacco. Although the development and promotion of intensive curing rooms and curing processes have promoted my country's great progress in tobacco leaf curing, However, there are still many problems in practical applications: In the heat supply of existing barns, coal combustion still occupies a large proportion. Although many scholars have done a lot of research on clean energy heating, they are limited by the development of baking technology and technology. The status quo, technology costs, etc., make it difficult for clean energy to be widely promoted and applied in the heating of intensive barns; In terms of dehumidification, the strong dehumidification method used not only causes a large amount of energy loss during the dehumidification process, but also reduces the proportion of high-quality tobacco leaves and the tobacco aroma of the tobacco leaves themselves; In terms of control, due to the limitations of the overall structure of the coal-fired intensive barn roasting system and the roasting process, the existing control system can only achieve semi-automatic and automatic, which requires a lot of labor, especially for experienced tobacco farmers.

In terms of control technology and baking process, although the existing intensive baking room has basically realized semi-automation and automation, it still depends on the length of time for temperature stabilization, heating speed, timing of dehumidification, timing of coal addition, and amount of coal during the baking process. Manual experience to control, and because the overall structure and baking process of the existing intensive baking room baking system are based on the dehumidification method of coal-fired heating and strong dehumidification, and because of the hysteresis and uncontrollability of coal-fired heating Due to the lack of research on control, the relatively advanced research has only achieved some results in automatic coal addition and automatic dehumidification, but still relatively in intelligent control, intelligent baking, and clustered baking. behind
