Is the tobacco leaves drenched in the rain well roasted, and how to roast the tobacco leaves in the

1. The middle and lower tobacco leaves with roasting value are harvested in a timely manner in the normal tobacco field, and the ripeness of the sedan waiter is not easy to be too high. For the green tobacco field, the lower leaves can be directly harvested and baked, and the middle leaves should be touched and the tobacco leaves should be harvested and roasted after the tobacco leaves are normally ripe. 2. The water content of tobacco leaves after rain is large, and the braided (clamped) tobacco is appropriately reduced, which is 10% less than normal, and can be hung on the smoke rack to drain the surface moisture before loading or close the air inlet door and humidity exhaust window of the oven after being installed in the oven, and open the fan to circulate to blow off the surface moisture.

During the baking process, take water first and then take the color, properly drain the moisture early, promote the tobacco leaves to soften and yellow, and avoid hard yellowing. Turn the fire in time, raise the temperature slowly, prolong the time of 45-47 years, and promote the whole yellow and fixed color of the tobacco leaf veins. For the tobacco leaves that are difficult to dehydrate and soften, you can use a short period of high temperature after ignition to take softness, generally 1 hour after ignition to raise the temperature to about 40, and the maintenance time is about 3 hours, subject to the softness of the tobacco leaves, and then cool down to 38-39 concentrated yellowing.

Rain tobacco, a kind of post-rain tobacco, refers to the tobacco leaves have been normally yellowed to be harvested, encountered short-term rainfall, so the leaves are moist, with obvious adhesion water. This type of tobacco can be roasted as long as appropriate measures are taken during roasting.

First of all, it is necessary to harvest in time after the rain stops, and appropriately reduce the amount of smoke in the oven. After being loaded into the oven, the method of "high temperature and multiple dehumidification" should be adopted to promote the wilting and yellowing of tobacco leaves.

The specific method is: after the tobacco leaves are loaded into the house, the skylight hole is closed tightly, after ignition, the temperature is raised to 40-42 degrees Celsius after 5-6 hours, and the temperature is maintained by the stable fire. After stopping for 2-3 hours, close the skylight and floor hole, and use 3-4 hours to raise the temperature to 44 degrees Celsius for the second dehumidification, if the dehumidification is not enough, the third time can be carried out.

After the water attached to the leaf surface is discharged, the skylight and ground hole are closed and baked according to the general baking method.

In addition, the "smoke drying method" can be used to remove water from the foliage. That is, in the yellowing period, the "smoke drying method" is used to drain moisture. The tobacco leaves are loaded into the roasting room, and after the fire, all the skylights are opened, and the hole in the ground is opened according to the actual needs, and after a period of time, the discoloration of the tobacco leaves is checked.

When the surface of the tobacco leaves is discharged with water, it is transferred to the normal baking process method for operation control.

Another situation of rain tobacco is that the tobacco leaves that have matured normally are affected by the continuous rain for a relatively long time, and then turn green. In this case, the rain smoke is more difficult to bake, and the roasting technique is slightly improper, which is easy to make the tobacco rot and roast.

The following measures should be applied to harvesting and baking techniques:

1) Harvest when the tobacco leaves turn slightly yellow again. If it rains for a long time, it should be harvested in time, otherwise the greening will be serious, and the middle and lower leaves will be prone to waterlogging, and the baking effect will be worse.

2) This kind of tobacco leaves have a very high water content, which can be quickly dehumidified at high temperature for many times, so as to promote the loss of water and softening of tobacco leaves, and apply a higher temperature to turn yellow, so as to shorten the yellowing time as much as possible. Turning yellow for 6-7 years will turn into the color setting period, and stabilize at 45-47 degrees Celsius for a long time, so that the tobacco leaves will lose a lot of water and continue to turn yellow, until the tobacco leaves are raised to heat up after the small cylinder.
