Abstract

The invention discloses a primary tobacco curing system with natural gas as an energy source. The system comprises a hot blast stove module, a curing barn module, a waste heat utilization module and an automatic control module. The natural gas is adopted by the hot blast stove module to generate hot air; air flowing is optimized by the curing barn module; heat energy of moisture removal air is recovered by the waste heat utilization module. By overall optimization, the automatic-operating efficient primary tobacco curing system with natural gas as the energy source is realized, moisture removal air and replenished air flow in crossed directions to raise the temperature of the replenished air, and accordingly natural gas consumption is reduced, energy source utilization efficiency is improved, fuel cost and labor cost in a primary tobacco curing process are reduced, and income of peasants is increased.

Description

technical field [0001] The invention belongs to the field of energy utilization, and in particular relates to a tobacco primary curing system powered by natural gas. Background technique [0002] my country is the country with the largest tobacco planting area in the world, and the output of flue-cured tobacco has ranked first in the world for many years. The mature flue-cured tobacco leaves in the field must complete the initial curing process soon after harvesting, that is, in the tobacco curing room, it can be prepared under a certain time and temperature and humidity environment to complete dehydration and drying and a series of other biochemical reactions. [0003] Tobacco curing system usually has the following characteristics: [0004] (1) The initial roasting of tobacco leaves requires certain humidity and temperature conditions, so it is necessary to continuously input hot air into the curing room from the outside to maintain a certain temperature in the curing roo...
