[0002]
BACKGROUND OF THE INVENTION
The brewing process at a tea factory is an almost final stage that further forms and drys tea leaves that have been processed through steaming, rough kneading, twisting, and middle mashing processes, and is responsible for this brewing process. The equipment is a tea making device.
[0003]
As shown in FIG. 5, the tea making device includes a platen 5 a ′ disposed on the upper surface of a bowl 5 ′ having a substantially arc-shaped cross section opened upward, and a gripping device 2 ′ disposed above the platen 5 a ′. The tea leaves are provided so as to be swingable, and the tea leaves supplied onto the grid 5a 'are swallowed by the gripping device 2'. At this time, the saddle platen 2A ′ and the saddle horse 22 ′, which are one of the components in the saddle device 2 ′, swing together.
[0004]
The bulk of the tea leaves put into the pot 5 'is greatly different between the initial stage and the end stage of the milling process. In order to perform sufficient koji processing even in the state, a configuration is adopted in which the distance from the grid 5a ′ is variable corresponding to the decrease in the bulk of the tea leaves.
[0005]
Specifically, by adopting a configuration in which one vertical portion of a lateral gall-type sword horse 22 'is connected to a heel platen 2A' located in the sword horse 22 'by a link 27', The scooping platen 2A 'swings with the saddle horse 22', and the scooping platen 2A 'moves up and down to make the distance between the scooping platen 2A' and the scooping plate 5a 'variable.
[0006]
However, according to such a configuration, the movement of the scooping platen 2A 'is a rotational movement around the fulcrum of the link 27' (the side of the handbrake 22 '). It will not be a movement.
For this reason, as shown in FIG. 5 (b), when the scooping platen 2A 'is lowered, the center of the scooping platen 2A' is shifted from the center of the saddle horse 22 '. The distance between the triangular tree 24 'and the leaf crust 23' provided on the horseshoe 22 'is different in the front and rear (left and right in FIG. 5), and the difference is up to about 1 cm. There is also.
[0007]
As a result, the tea leaves wrap around to the upper side of the crushing platen 2A 'from the portion where the interval between the triangular tree 24' and the leaf roughness 23 'is widened, which adversely affects the finishing process. There was a thing.
[0008]

According to the present invention, even when the scooping platen moves downward in response to the decrease in the tea leaf bulk accompanying the progress of the milling process, the scooping platen is equally spaced from the front and back horses. Therefore, the tea leaves do not wrap around the platen and the brewing process by the tea brewing apparatus can be stably performed from the initial stage to the end stage of the brewing process.
Moreover, since the pin slides with respect to the rail, the pressure platen can be rotated in the front-rear direction, and the center of the heavy pressure applied to the tea leaf by the pressure platen is mutually converted in the rotation direction. Does not interfere with the movement that helps invert mixing.
Furthermore, when such a structure is configured in an existing apparatus, it can be handled only by exchanging parts, so that an inadvertent cost increase is not caused.
[0010]
In addition to the above requirements, the tea making apparatus according to claim 2 is configured such that the horse and horse are connected by a link, and a play is provided at a connection portion between the link and the cup. It is characterized by being.
According to the present invention, since the vertical movement of the pressure platen is not limited by the structure of the link, the movement of the pressure platen becomes a rotational movement around the fulcrum of the link horse as in the conventional structure. There is no.
Moreover, the movement which assists the inversion mixing of the tea leaves when the center of the heavy pressure on the tea leaves by the rolling plate is mutually converted in the rotation direction is not hindered.
The above problems can be solved by using the configuration of the invention described in each of the claims as a means.

[0020]
The pressurizing device 3 has the above-described configuration as an example, and by changing the position of the weight 33, the magnitude of the pressure of the scooping platen 2A is adjusted. Of course, the pressing of the pressing platen 2A is not necessarily performed by a weight, and other mechanisms such as a spring, a cylinder or the like that can change the pressing force may be used.
[0021]
The tea making apparatus 1 according to the present invention has the structure as described above as an example, and the operation mode thereof will be described below.
First, the temperature of the firebox 5b, the pressurization pattern, the pressurization time, the reciprocating speeds of the horseshoe horse 22 and the leaf blade 23, etc. are set according to the model of the tea making apparatus 1 and the characteristics of the tea leaves A, etc. The tea leaves A that have been subjected to the intermediate cooking process are supplied from a supply pool (not shown) to the kettle 5 in the tea making apparatus 1 set in this way.
[0022]
The tea leaves A supplied into the kettle 5 are squeezed by the handgrip device 2, and as the processing proceeds, the moisture content decreases and the bulk of the tea leaves A from the state shown in FIG. When the pressure decreases to the state shown in b), the scooping platen 2A that tends to be pushed downward by the pressurizing device 3 is lowered.
[0023]
At this time, the distance between the triangular tree 24 provided on the crushing platen 2A and the leaf crust 23 provided on the saddle horse 22 is the same size at the front and rear (left and right in FIG. 3) regardless of the vertical position of the crushing platen 2A. Therefore, the tea leaves A do not wrap around the punching platen 2A, and the milling process can be stably performed from the initial stage to the end stage of the milling process.
[0024]
At this time, the pin 28 slides with respect to the rail 25, and the movement of assisting the inversion mixing of the tea leaves A when the centers of the heavy pressures on the tea leaves A by the scooping platen 2A are mutually converted in the rotation direction. Since there is no hindrance, it is possible to perform suitable scouring without impairing the performance of the existing tea brewing apparatus 1 that reproduces the unique movement of finishing squeezing manually.
[0025]
Furthermore, in constructing such a structure related to the scooping platen 2A shown in the present embodiment in an existing apparatus, it is possible to cope with only the addition of the rail 25 and the replacement of the parts of the pillow block 26 and the link 27. Cost does not increase.
[0026]
[Reference form]
In the previous embodiment, the rail 25 is used as the linear track provided in the horseshoe 22, but the point is that if the trajectory during the vertical movement of the scooping platen 2A can be made constant, it is the same as the present invention. An effect can be produced, and such a configuration is shown below as a reference form.
[0027]
Specifically, as shown in FIG. 4, the linear trajectory is a shaft 35 attached so as to be positioned at the center of the opposed vertical portion with respect to the saddle horse 22. The bosses 36 provided at the centers of the left and right sides of the upper surface of the scooping platen 2A are slid, and the bosses 36 are configured to be rotatable in a vertical plane.
[0028]
In the case of adopting such a configuration, since the linear track is formed by the shaft 35, the trajectory when the scooping platen 2A moves up and down can be made constant.
Further, since the boss 36 is rotatable in a vertical plane, it does not hinder the movement of assisting the inversion mixing of the tea leaves A when the centers of the heavy pressures on the tea leaves A by the scooping platen 2A are mutually converted in the rotation direction.
