How to drain moisture naturally from flue cured tobacco, and how many degrees does flue cured tobacc

Hello dear, it is a pleasure to serve you! For you, the dry bulb rises to 40 or 41 and the wet bulb starts to drain at 37 or 38.

1. Baking temperature and humidity control: the temperature should be slow, the temperature should be accurate, the moisture should be slow, the temperature should be avoided, the humidity should fluctuate and turn yellow: 4-6 hours to 38 degrees, 4-6 hours, and then 2 degrees per hour to 41-42 degrees, the temperature to the second grade tobacco leaves to yellow 7-8 degrees, and then to 43-44 degrees, so that the whole furnace tobacco leaves are all yellow, and turn into the color fixing period.

Coloring period: This period requires a relatively high temperature and a lower relative humidity, that is, the moisture in the tobacco leaves must be removed at a faster rate, so that the leaves are gradually dried, that is, the process of slowing down or terminating the discoloration speed and speeding up the drying speed. The key to the simultaneous heating and dehumidification during the color fixing period is the temperature of the sensitive bulb of the wet ruler is 42-50 degrees (38-39 degrees of wet bulb temperature) in the early stage of color fixing, and 50-55 degrees (40-41 degrees of wet bulb temperature) in the late stage of color fixing.

Dry tendon stage: the main vein moisture is removed, mainly the drying process of evaporation and loss of smoke tendon water. The temperature of the dry gluten should not be too high in the later stage, otherwise it will lead to the volatilization and loss of aroma substances of tobacco leaves.

Summary. Hello dear to the flue-cured tobacco when it is baked for 35-36 hours, start to drain the moisture.

Hello dear roasting stage: After the start of roasting, the time of dehumidification depends on the moisture content of the tobacco leaves, the amount of tobacco and the climate. If the tobacco leaves have high moisture content, large tobacco loading, and roasting in rainy days, after ignition, open the air inlet and humidification (manual control) system, and use a high-speed circulating fan to discharge excess moisture on the surface of the tobacco leaves, stabilize the temperature of 35-36, and adjust the temperature difference between the upper and lower layers by about 1.

On the contrary, the automatic control of the grinding and discharging program is directly used to remove the moisture. Yellowing stage: In the 38 39 yellowing stage of tobacco leaves, the timing of ventilation and moisture removal is determined according to the degree of yellowing of tobacco leaves.

Usually, the wet bulb temperature is set to 35 36, during which the automatic controller will automatically remove the wet according to the change of the set parameters and the actual measured value. Generally, roasting for about 36 hours (including roasting tobacco leaves with low moisture content) requires an appropriate amount of ventilation and moisture removal. Late ventilation and moisture drainage, insufficient water loss of tobacco leaves, easy to cause tobacco leaves to turn hard and yellow, difficult to dehydrate and fix color, poor color after roasting, dark luster, and low quality.

Hello. Bottom temperature, why temperature and humidity are the same.

Above is the method of roasting.

Just now** began to drain the humidity temperature can't go up, can't ** just drain the humidity.

Hello dear! Nice to meet you Generally speaking, the temperature of flue-cured tobacco is controlled at about 50 -60 at the beginning of roasting, and at this time, it is necessary to continuously supply air to cool down and remove the accumulated moisture in the oven; When the water on the surface of the flue-cured tobacco is basically evaporated, and the surface of the flue-cured tobacco is brown, the roasting temperature can be appropriately increased to about 70 -80, and the dehumidification steam engine can be turned on at the same time for dehumidification treatment. Adjust the temperature control and dehumidification time according to the actual situation, and keep the main trunk of the flue-cured tobacco evenly and evenly roasted.

I hope my manuscript can be helpful to you. If you think I'm useful, I hope to give it a thumbs up! <>

Summary. Expansion: A special house for the primary processing of mature flue-cured tobacco leaves, mainly including a smoke room, heating equipment and ventilation system.

There are two forms of flue-cured tobacco room: natural ventilation and mechanical ventilation. Natural ventilation includes airflow ascending type, airflow descending type and roadway (tunnel) type. These flue-cured tobacco rooms can also be equipped with axial flow fans as auxiliary equipment for moisture removal; Mechanical ventilation is the dense (stacked) flue-cured tobacco room, and the ordinary flue-cured tobacco room (see figure) and dense flue-cured tobacco room with natural ventilation and rising airflow are the most commonly used.

What system are you asking? Can you tell me the model number?

Jiaye controller.

In fact, you don't need to cancel it if it's set. 1.If the humidity is not high, it will be discharged automatically, 2If the humidity is high, it will kick in. It doesn't affect your work. Therefore, if you don't have friends, you will have to worry about Nahan.

How do I cancel??

Can you tell me what system it is?

You might as well take a picture of his nameplate for me to see.

If it's in English. Select Dehumidification and click Cancel

This is a normal phenomenon, at this time to pay attention to ventilation and moisture discharge, under normal circumstances, the sky, the ground and the window each open 1 4 1 3. After ventilation and dehumidification, the temperature rises slowly to 43 per hour. Keep 43, so that the tobacco leaves are fully soft and collapse (collapse frame), the tobacco tendons become soft, fold and continue, and the leaves are basically all yellow (more than ninety percent), at this time the dry and wet difference requires 6 7, the sky and ground windows should be opened again, each open 1 2 1 3.

The skin difference per limb is 1 per hour to 45, and the ventilation and moisture drainage are strengthened, and the color fixing period is transferred. It takes about 48 hours to change the grip.
