Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for processing tea leaves that are continuously discharged or conveyed in small amounts by a continuous tea making machine or a conveying machine into a batch type tea making machine in which the amount of processing per time is specified. This relates to a weighing device that measures and transports or dispenses a predetermined amount.

There are several examples of transitioning from a continuous tea machine to a batch tea machine in a tea production line, but steam machines,
When moving from a continuous tea machine with a cooling machine to a batch-type coarse rolling machine, conventionally a measuring device is installed on the coarse rolling machine that can measure the specified amount of tea in the coarse rolling machine at one time, and the tea is sent one after another from the cooling machine. When the tea leaves reach the specified amount, they are fed into a coarse rolling machine. Tea leaves that are steamed in a steamer are cooled by ventilation while passing through a cooler, but they are still susceptible to deterioration.
The tea leaves are loaded one after another until the specified amount is accumulated in the scale, or if there are any previous tea leaves in the coarse crusher, they remain loaded in the scale until the previous tea leaves have been taken out. However, depending on the nature of the tea leaves and the degree of steaming, the quality may deteriorate significantly.
This is one of the causes of deteriorating the quality of tea.

The purpose of this invention is to improve the measuring mechanism required when transitioning from a continuous tea machine to a batch tea machine, and to improve the measuring mechanism that is required when moving from a continuous tea machine to a batch tea machine, and to eliminate the conventional method of placing tea leaves on a measuring machine for a long time. The purpose is to eliminate the negative effects and improve the quality of tea.

An embodiment of this invention will be described based on the drawings.
1 is a steamer that steam-processes raw tea leaves; 2 is a cooler that passes steam-heated tea leaves to a high temperature to cool them; 3 is a tea leaf discharged from the cooler 2 and conveyed by a horizontal conveyor 16 and a vertical conveyor 17; Receiving 3-10
A measuring device that can measure the desired amount W between [Kg], 4
6 is a cylinder that automatically opens and closes the take-out door 5 on the bottom surface based on the electrical signal each time a set amount W of tea leaves is measured by the measuring device 3, and 6 stores the number n of times the measuring device 3 measures and drops tea leaves. The counter 7 has its starting end placed under the measuring device 3, and its ending end placed at the batch type coarse kneading machine 10.
It is a belt conveyor placed above the belt 8, and the belt 8 is made of a ventilation member such as a wire mesh, and a blower 9 sends cold air. The conveyor 7 operates for several seconds S each time the measuring device 3 measures and drops a set amount W of tea leaves, and the total number of tea leaves measured by the measuring device 3 is n x W.
When [Kg] reaches the predetermined amount M of the coarse crusher 10, the tea leaves on the belt 8 are all operated to be thrown into the coarse crusher 10.

The tea leaves that have been continuously steam-treated in small amounts with steam 1 are then ventilated and cooled by a cooler 2, and are continuously discharged in small amounts from the end extraction section. The tea leaves that are continuously conveyed in small amounts from the horizontal conveyor 16 installed under the take-out section via the vertical conveyor 17 are weighed in small amounts W (for example, 10 [Kg]) and dropped onto the belt conveyor 7. Conveyor 7 is where the tea leaves are weighed and
Each time the belt is turned on, the S operates for a few seconds, so if the speed of the belt 8 is vm/S, there will be S×v on the belt 8.
Tea leaves are placed at a pitch of [m]. Pituchi S×
It is preferable for v [m] to be such that there is some space between each tea leaf W. The specified throughput M of the batch type roughing machine is
If it is 100 [Kg], the number n of counter 6 is M/W
= If you reach 10 times, 100 [Kg] on belt 8
, the conveyor 7 is operated and the tea leaves are fed into the coarse rolling machine 10 all at once. When the feeding is completed, the measuring device 3 and the belt conveyor 7 return to the initial state, and the measurement is continued until the specified amount M is reached.
Repeatedly dropping or starting and stopping. Sho belt 8
While the tea leaves W are placed on top at a pitch of S x v [m], the blower 9 blows cold air, so the tea leaves on the belt 8 made of a ventilation member are sufficiently cooled and have the effect of preventing deterioration. Become bigger.

In this invention, an automatic take-out measuring device 3 that weighs small amounts of W and a conveyor 7 that operates based on the take-out signal of the measuring device 3 are integrally connected, and the tea leaves W are collected until they are fed into the coarse rolling machine 10. The tea leaves are placed on the belt at predetermined intervals, and the tea leaves are transported and introduced when the total amount n x W reaches the specified amount M of the batch type tea machine for the next process, so the time it takes to load the tea leaves into the measuring device 3 is shortened. Belt 8 with a short, small amount of W at a pitch of S x v [m]
The tea leaves placed on top are sufficiently exposed to the outside air and cooled, which has a great effect on preventing deterioration of the tea leaves.Also, since the measuring device has been made smaller, measuring accuracy has been increased, and batch-type tea machines are not strained. do not have.

In conventional batch-type tea machines, when introducing tea leaves, a specified amount of tea leaves is fed all at once, which puts a load on the kneading hands and leaf grinders that knead and stir the tea leaves, as well as the drive unit that rotates them, causing damage. However, since the present invention gradually supplies the material using a conveyor, the kneading hands and the like are not damaged.

In addition, FIG. 2 shows another embodiment, and 11
12 is a continuous rough kneading machine, 12 is a take-out conveyor of the continuous rough kneader 11, 13 is a horizontal conveyor, 14 is a vertical conveyor, and 15 is a batch kneader. The second purpose is to install the starting end under the measuring device 3 and the other parts under the roughing machine 11 to increase the installation area.

As described above, this invention improves the tea leaf measuring mechanism required when transitioning from a continuous tea machine to a batch tea machine process, eliminates the adverse effects of loading tea leaves on a measuring device for a long time, and improves the quality of tea. It is something.
