Problems solved by technology

The dried tobacco leaves in the conventional intensive curing barn are easily broken after baking, so they cannot be collected directly. Usually, they are naturally cooled with the barn, and collected after the dried tobacco leaves regain moisture and become soft. Due to the high stacking density of the tobacco leaves in the barn and the closed space The moisture regain is slow, generally it takes 1.5 to 2 days to regain the moisture, so that the turnover period of the flue-cured tobacco room is as long as 8 days, and the moisture regain of the dried tobacco after curing needs to be solved

Embodiment 1

[0025] Example 1: Tobacco leaves in the middle of Cuibi No. 1 in Sanming, Fujian Province are baked in an intelligent flue-curing room 3. The steps of the curing process are as follows: Step 1: Arrange the mature fresh tobacco leaves in the conventional flue-curing room after weaving rods. The form is placed in a well-ventilated tobacco shed until the tobacco leaves are 30% yellow and slightly soft; in the second step, the dry bulb temperature is raised to 37.5°C at a rate of 1°C / h, and the wet bulb temperature is controlled at 36°C for 10 hours. , the fan speed is 1000r / min, so that the tobacco leaves are 60% yellow; in the third step, the dry bulb temperature is raised to 40°C at a rate of 0.5°C / h, and the wet bulb temperature is controlled at 37°C for 20h; the fan speed is controlled at 1200r / min , so that the tobacco leaves are 90% yellow and the tobacco leaves are pointed and curled; the fourth step is to increase the dry bulb temperature to 46°C at a speed of 0.5°C / h, whi...

Embodiment 2

[0026] Example 2: Tobacco leaves in the middle of Cuibi No. 1 in Sanming, Fujian Province are baked in an intelligent flue-curing room 3. The steps of the baking process are as follows: Step 1: Arrange the mature fresh tobacco leaves according to the conventional arrangement in the flue-curing room. The form is placed in a well-ventilated tobacco shed until the tobacco leaves are 30% yellow and slightly soft; in the second step, the dry bulb temperature is raised to 38.5°C at a rate of 1°C / h, and the wet bulb temperature is controlled at 37°C for 20 hours. , the fan speed is 1200r / min, and the tobacco leaves are 60% yellow; in the third step, the dry bulb temperature is raised to 42°C at a rate of 0.5°C / h, and the wet bulb temperature is controlled at 38°C for 30h; the fan speed is controlled at 1300r / min , until the tobacco leaves are 90% yellow and the tobacco leaves are hooked and curled; the fourth step is to increase the dry bulb temperature to 48°C at a speed of 0.5°C / h, ...

Embodiment 3

[0027] Example 3: Tobacco leaves in the middle of Cuibi No. 1 in Sanming, Fujian Province are baked in an intelligent flue-curing room 3. The steps of the baking process are as follows: Step 1: Arrange the ripe fresh tobacco leaves in a conventional flue-curing room after braiding the rods The form is placed in a well-ventilated tobacco shed until the tobacco leaves are 30% yellow and slightly soft; in the second step, the dry bulb temperature is raised to 38°C at a rate of 1°C / h, and the wet bulb temperature is controlled to 36.5°C. 12h, the fan speed is 1080r / min, and the tobacco leaves are 60% yellow; in the third step, the dry bulb temperature is raised to 41℃ at a rate of 0.5℃ / h, and the wet bulb temperature is controlled at 37.5℃ for 22h; the fan speed is controlled at 1260r / h Min, to make the tobacco leaves 90% yellow, and the tobacco leaves are hooked and curled; the fourth step is to increase the dry bulb temperature to 47°C at a speed of 0.5°C / h, while controlling the...

Abstract

The invention provides an online intelligent tobacco curing system based on a cloud platform and a curing process. The online intelligent tobacco curing system based on the cloud platform comprises a tobacco curing system server, a terminal application system and no less than one intelligent tobacco curing barn, wherein the three parts are connected by virtue of an internet; the tobacco curing system server is capable of receiving real-time data information of the plurality of intelligent tobacco curing barn, and the tobacco curing system server, by shooting images tobacco leaves and monitoring the tobacco leaves and by conducting computation and analysis with the application of big data of a tobacco curing stem server cloud platform, can achieve online intelligent control; and the terminal application system (such as PC, iPad and mobile phone) can log in a web page or mobile phone APP to search the status and historical data of the tobacco curing barn; the curing process comprises five sections in seven steps, namely weaving tobacco leaves and pre-withering the tobacco leaves, a yellowing stage, a leaf-drying stage, a stem-drying stage and a dried tobacco leaf moisture regaining stage, and a temperature stabilizing stage from the second step to the seventh step is subjected to the intelligent control of the tobacco curing system server cloud platform. The online intelligent tobacco curing system provided by the invention has the characteristics of being precise in temperature control, energy-saving and emission-reduction, environment-friendly, low in cost, short in curing cycle and intelligent and capable of achieving big data management, and the online intelligent tobacco curing system is conducive to the development of professional curing.

Description

technical field [0001] The invention belongs to the technical field of curing equipment and curing technology, in particular to the technical field of tobacco curing equipment and curing technology, and particularly relates to an online intelligent tobacco curing system and curing technology based on a cloud platform. Background technique [0002] Due to the requirements of national energy conservation, emission reduction and environmental protection, coal-fired heat source will be gradually replaced by other heat sources such as biomass fuel particles or biomass gas, solar auxiliary energy, heat pump electric oven, infrared electric oven. room etc. The heat pump electric barn has obvious advantages: reduce the impact of loose coal combustion on the environment, forced hot air circulation flue-cured tobacco has no heat and exhaust gas emissions, is more energy-saving and environmentally friendly, adopts frequency conversion motor control to achieve stepless control, higher c...
