Description

  The present invention relates to a fixed barrel type tea machine capable of producing a good quality tea making in a batch process and a continuous process in an initial process in a green tea processing process. In the present specification, the “fixed-cylinder tea machine” is a general term for tea machines such as leaf cutters and coarse rice cake machines. Further, in this specification, “batch” is a process performed by batch processing and dividing a predetermined amount, and is used as a term for “continuous”.

  Green tea is produced through various processing steps such as steaming, rough kneading, twisting, and finishing. In the steaming process, fresh leaves are steamed, and in the next rough rice cake process, tea leaves are sown in a fixed barrel type tea machine, and the first leaf blower is placed at the beginning of the rough rice cake process, And the ugly hand rotates, beats the tea leaves, and removes and dries the tea leaves. Then, the tea leaves are further used to remove and dry the water from the tea leaves using a hand. Next, it is rubbed while being continuously transferred to an intermediate machine (back intermediate machine), a precision machine or the like.

  Conventionally, a tea factory has selected either a batch type or a continuous type in consideration of the production amount, target quality, and the like. Regardless of which format was selected, it was not possible to cope with changes in target quality and production volume. In particular, for small quantities of high quality tea such as No. 1 tea such as “Miru-bud”, the batch method is preferred for a certain time every time, and the continuous method has a disadvantage that the quality varies. . In particular, it is because the time for tea leaves to remain in the fixed-cylinder tea machine cannot be made constant. That is, in the continuous type, there is a difficulty in focusing on quality. Furthermore, in the case of No. 2 tea and the like, since the amount of tea leaves is large, it is important to aim for mass production as a continuous type.

By the way, there are two types of conventional hitting machines or roughing machines. That is, a batch type and a continuous type. In the batch method, a predetermined amount of tea leaves conveyed by the transfer conveyor from the steaming process are temporarily stored in a measuring instrument or the like provided at the top of the machine frame, and then the stored tea leaves are collected at once from the inlet at an appropriate timing. After being put in the fixed cylinder and processed in the fixed cylinder for a predetermined time, the bottom surface of the fixed cylinder is opened, and the tea leaves in the fixed cylinder are discharged onto the transfer conveyor all at once and transferred to the next twister or the like. In the continuous type, the tea leaves transported by the transfer conveyor from the steaming process are continuously fed into the fixed barrel through the slot provided in the upper part of the machine frame, and at the same time, the fixed barrel is removed while the leaves are beaten with a scooping hand. The product is sent to the outlet side, continuously discharged from the outlet onto a transfer conveyor below the fixed barrel, and transferred to the next twister or the like.

Patent Document 1 that satisfies the conditions of the batch type and the continuous type is disclosed, and in the case of the continuous type, a configuration is disclosed in which adjustment is performed by an adjustable tea leaf hand. It is troublesome and time-consuming to adjust the angle each time between the fixed type and the continuous type.
Therefore, the problem (technical problem or purpose) to be solved by the present invention is that the fixed type and the continuous type can be easily and quickly performed under such circumstances, and the simple configuration is relatively inexpensive. It is to realize a fixed barrel type tea machine that can be provided.

  Accordingly, as a result of intensive researches to solve the above-mentioned problems, the inventor has rotated the invention of claim 1 into a bowl-shaped fixed cylinder having an extraction door that can be opened and closed over substantially the entire bottom surface, and the fixed cylinder. A tea leaf scooping hand that is possible but cannot be adjusted, an outlet disposed on one end side in the longitudinal direction of the fixed cylinder, and the other end opposite to the outlet in the longitudinal direction of the fixed cylinder And a measuring instrument capable of measuring tea leaves just before the end inserting port. In the case of batching, a predetermined amount of tea leaves is measured by the measuring instrument. The tea leaves are closed after the take-out port and the take-out door are closed, and after the tea leaves are put into the end slot and a predetermined amount of tea leaves are scooped in the fixed barrel by the scooping hands. When it is discharged from the extraction door and is continuous, the extraction door is closed and the extraction door is closed. Is opened, the tea leaves are always thrown into the end slot, and the tea leaves are crushed in the fixed barrel by the scooping hands, and then the tea leaves are opened while being sent in the direction of the outlet. Furthermore, the problem was solved by using a fixed barrel type tea machine characterized by being discharged from the outlet. According to a second aspect of the present invention, in the first aspect of the present invention, there is provided a fixed cylinder, wherein a grip is rotatably disposed in the fixed cylinder, and the manual rotate in synchronism with the cradle. The problem was solved by using a mold tea machine.

  According to a third aspect of the present invention, there is provided a bowl-shaped fixed barrel having a take-out door that can be opened and closed over substantially the entire bottom surface, a tea leaf scooping hand that is rotatably arranged in the fixed cylinder and is not adjustable, An outlet disposed on one end side in the longitudinal direction, an end insertion port disposed on the other end side opposite to the outlet in the longitudinal direction of the fixed barrel, and a longitudinal direction of the tea machine body In the case of batching, a predetermined amount of tea leaves is measured with a central charging port disposed at a substantially central position and a measuring device capable of measuring tea leaves immediately before the central charging port. The tea leaves are closed after the take-out door and the take-out door are closed, and after a predetermined amount of tea leaves are scooped in the fixed barrel by the scooping hands, When it is discharged from the take-out door and is continuous, the take-out door is closed and the With the outlet being opened, the tea leaves are always put into the end slot, and the tea leaves are crushed in the fixed barrel by the scooping hands, and then the tea leaves are opened while being sent in the direction of the outlet. The above-mentioned problems have been solved by using a fixed barrel type tea machine characterized by being discharged from the outlet. According to a fourth aspect of the present invention, there is provided the fixed cylinder according to the third aspect, wherein a grip is rotatably disposed in the fixed cylinder, and the grip is rotated synchronously with the gripper. By using a mold tea machine, the above-mentioned problems are solved. All of the “tea leaves” or “steamed tea leaves” that are put into the fixed barrel type tea machine of the present specification are simply referred to as “tea leaves”.

  First, in claim 1, even if the tea leaves are put into the end insertion port in a continuous manner or a batch manner, the tea leaves gradually flow toward the other end side by a rotating hand. In other words, it has been found from experiments and empirical rules conducted by the applicant that the steamed tea leaves exhibit a state in which fluid flows when the tea leaves rotate. For this reason, the tea leaves smoothly transition from one end side to the other end side in the longitudinal direction of the tea making machine main body without adjusting the angle of the scooping hand. Thereby, it can be a continuous type or a batch type. Further, in the invention of claim 2, the squeezing operation is added to the configuration of claim 1 to remove and dry the water from the tea leaves. Further, in the case of the batch type, the quality is particularly emphasized in the case of the batch type, and when the tea leaves are introduced from the central insertion port, the tea leaves gradually flow in both directions with a rotating grinder. As a result, the roughing process can be improved. In addition, the invention of claim 4 adds a squeezing operation to the configuration of claim 3 with a squeezing hand to remove and dry the moisture of the tea leaves.

  According to the first aspect of the present invention, it is possible to use a continuous type or a batch type without any adjustment of the angle of the scoop. For this reason, not only the operation is simplified, but there is an advantage that a relatively cheap continuous type or batch type fixed barrel type tea machine can be provided. In the second aspect of the present invention, the removal of moisture can be improved by adding a hand to the first aspect of the present invention. In the invention of claim 3, particularly in the case of a batch type, the maximum effect that the quality can be made better than the fixed barrel type tea machine having the structure of claim 1 is exhibited. In the invention of claim 4, compared with the invention of claim 3, moisture removal is improved by the addition of a hand.
