Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to displaying an ideal air volume and a hot air temperature for each medium-fire process in a drying line based on humidity measured by a humidity sensor installed at a desired position in the drying line. Accordingly, the present invention relates to a tea leaf drying line management device for totally managing tea leaves from the humidity of the entire drying line.

[0002]

2. Description of the Related Art Generally, a drying line of a tea factory has a medium-fire process consisting of a plurality of rubbing and drying machines such as a leaf driving machine, a rough rubbing machine, and a medium rubbing machine. As a result, dried tea leaves in the shipping state are obtained. Since the drying of tea leaves in each medium-fire process is mainly performed by hot air output from the furnace of each kneading dryer, it is important to adjust such hot-air conditions optimally in each medium-fire process, which is related to the quality of tea leaves. Elements.

Conventionally, the adjustment of the hot air has been performed by measuring the temperature and humidity of the air taken into the furnace and determining the optimum values of the hot air temperature and air volume based on the state value of the air. . That is, a dry-wet bulb thermometer (one of the two bar-shaped thermometers is wrapped in gauze wet with water) and a humidity sensor are arranged near the air inlet of the furnace of each kneading dryer. In advance, the output of the hot air was managed to be an ideal value based on the measurement value by the dry / wet bulb thermometer or the humidity sensor and various conditions of the tea leaves put in.

[0004] The optimum hot air temperature is set based on the value measured by the dry-wet bulb thermometer and the desired tea temperature (target tea temperature). That is, the temperature of the hot air to be adjusted is obtained from a table (table) using the dry bulb temperature and the wet bulb temperature created for each tea temperature as input data, and based on this, the furnace of each massaging dryer is determined. Was adjusted to adjust the hot air temperature.

On the other hand, the air volume is a factor that affects the drying speed of tea leaves or the quality and production efficiency of tea. If this air volume is too large, the surface and the tip of the tea leaf are dried and become a so-called upper-dry state, and the flavor changes along with the leaf color change due to the crushing and shrinkage of the tea leaf or the increase in tea temperature,
It is known that if the air volume is too small, the drying efficiency is reduced, and the leaves and quality of the tea leaves are reduced.
The optimum air volume at which such a problem does not occur is determined by an arithmetic expression or the like in consideration of the measurement value of the hygrometer.

The specific method for calculating the optimum air volume and hot air temperature has been described above. From the viewpoint of the moisture content of tea leaves,
As shown in FIG. 11, as the drying time elapses, drying is performed so that a predetermined curve is drawn from the input of tea leaves to the extraction thereof. In such a curve, the drying time and the curvature are set by the operator according to the quality of the drying line and the tea leaves, etc., and the air volume of the furnace is determined in consideration of the drying condition in the previous process so as to approach the set curve. And the hot air temperature was adjusted.

[0007]

However, in the above-mentioned conventional management device, a specific machine is to be managed among a plurality of kneading and drying machines arranged in a drying line, and an ideal is set for each kneading and drying machine. Although the air volume and the hot air temperature can be adjusted as described above, since the air volume and the hot air temperature of each kneading dryer are not adjusted by grasping the humidity of the entire drying line, there are the following problems.

[0008] That is, the drying line may have a different line configuration depending on the type and quality of the tea leaves, and the drying capacity of the kneading dryer used in each step is various depending on the tea factory or the drying line. Therefore, even if an ideal drying state is achieved in a given kneading dryer, drying in another kneading dryer may not be ideal, and the resulting tea leaves cannot always maintain high quality.

That is, as shown in FIG. 12, in an ideal drying curve from the introduction of tea leaves to the drying line to the removal thereof, a predetermined massaging dryer in which the ideal air volume and hot air temperature are not set is a. If a medium heat process is performed in the section, the moisture content of the tea leaves will deviate from the ideal curve, resulting in a decrease in the quality of the obtained tea leaves and a prolonged production time, adversely affecting the entire drying line. Will be.

[0010] In each of the kneading and drying machines, the air volume and the hot air temperature are adjusted according to the initial conditions of the tea leaves to be put into the kneading and drying machine (moisture of the tea leaves taken out of the previous step, etc.). Even when the drying machine deviates from an ideal drying curve while performing the medium heat process, it is difficult to adjust the air volume and hot air temperature during the drying. That is, if these changes are made during the drying, the process time will be prolonged or the amount of water taken out will be changed, which may affect the subsequent process and break the line balance.

On the other hand, in a tea factory, devices using steam such as a steamer are provided, or hot air is exhausted from a kneader and dryer, so that the humidity may be different at each location in the factory. At the same time, the humidity changes due to changes in weather during the day and night, even during the day, so it is necessary to review the air volume and hot air temperature in order to make tea with the optimal air volume and hot air temperature.

[0012] The present invention has been made in view of such circumstances, and by grasping the humidity of the entire drying line and adjusting the air volume and hot air temperature of each kneading dryer, the tea leaves as a final product are always produced. An object of the present invention is to provide a management apparatus and a management method in a tea leaf drying line that can maintain high quality.
