Abstract

The utility model relates to a stone mill for fine powdered tea, which comprises an upper mill and a lower mill. The upper mill and the lower mill can relatively rotate and are respectively provided with mutually opposite abrasive surfaces, and a concave cavity is at least formed on the abrasive surface of the lower mill. The speed of grinding tea leaves from the center of the stone mill towards the outer periphery of the stone mill can be decelerated by the aid of the concave cavity formed between the upper mill and the lower mill, in other words, the concave cavity arranged on the lower mill has a certain buffering function for the tea leaves being grinded from the center of the stone mill towards the outer periphery of the stone mill, so that the tea leaves are grinded more finely so as to meet the requirement of manufacturing the fine powdered tea.

Description

Smear the tea stone mill

Technical field

The utility model relates to a kind of stone mill, relates in particular to a kind of stone mill of smearing tea that is used to make.

Background technology

Smear tea, be milled into the micro mist shape green tea.The stone mill of mill tea often is called the tea mill, and they are different with common stone mill.China utility model patent 200620135720.X has disclosed a kind of electronic micro mist stone mill.The section shape of this stone mill is formed with selenodont cavity 9 up and down as shown in Figure 7 between Mo the abradant surface.This cavity 9 be abradant surface by last mill to being recessed on, the abradant surface of following mill raises up and forms.Tealeaves enters the back and is ground in this cavity 9.

Tealeaves is fully levigate, and tealeaves can not be too fast to the speed of stone mill peripheral part from stone mill central part mill, can not satisfy the requirement of smearing tea otherwise grind the tea dust that takes.And above-mentioned this stone mill, be provided with recessed cavity at last mill, be provided with projection at following mill simultaneously, tealeaves enters abradant surface after entering stone mill soon, accelerated tealeaves by from the speed of stone mill central part mill to the stone mill peripheral part, tealeaves can not get grinding just to have come out from stone mill fully, and tealeaves just can not be ground very carefully, can not satisfy the quality requirement of smearing tea.

The utility model content

For this reason, technical problem to be solved in the utility model is to provide a kind of and tealeaves fully can be ground, so that granularity reaches the enough thin tea stone mill of smearing.

For reaching above-mentioned purpose, the utility model provides a kind of tea stone mill of smearing, and comprises relatively turnable upward mill and following mill, and has relative abradant surface separately, and wherein, the abradant surface that grinds is formed with recessed cavity at least down.

Preferably, the described abradant surface of going up mill and grinding down all is formed with recessed cavity, and the female cavity is a dome shape.

Preferably, the radius of curvature of the female cavity equates.

Preferably, the described recessed cavity radius of curvature of mill that goes up is less than the described recessed cavity radius of curvature of mill down.

Preferably, the described recessed cavity radius of curvature of mill that goes up is greater than the described recessed cavity radius of curvature of mill down.

Preferably, the cross section that constitutes of the recessed cavity of the described recessed cavity of going up mill and described mill down is and laterally has two tips, vertically has the shape of two outer convex arcs up and down.

Preferably, the described abradant surface edge of going up mill and the described abradant surface edge of mill down be smooth and mutually driving fit be in the same place, the radial width of driving fit portion is below 1/5 or 1/5 of radius.

Preferably, the described at least outer surface of mill down is smooth, in order to avoid adhere to tea-leaf power.

Stone mill of the present utility model all is formed with recessed cavity on the abradant surface that grinds up and down, when mill relatively rotates up and down, tealeaves at first enters in the recessed cavity, tealeaves can phase mutual friction in recessed cavity before entering abradant surface, and at first accumulate in down the recessed cavity center portion of mill from the tealeaves that stone mill central authorities enter, this central part is the darkest part, make tealeaves when being ground, can slowly be ground to the graphite peripheral part from the stone mill central part, therefore, can increase stop and the polished time of tealeaves in stone mill.In other words, particularly owing to be provided with recessed cavity on the mill down, compare with the stone mill that recessed cavity is not set on following mill, tealeaves can slow down from the speed that the stone mill central part is ground to the stone mill peripheral part, the recessed cavity that mill upward is provided with is promptly ground to the stone mill peripheral part from the stone mill central part tealeaves has certain cushioning effect, thereby make tealeaves be ground carefullyyer, make the requirement of smearing tea to satisfy.

The specific embodiment

Shown in Fig. 1-5, the utility model is a kind of tea stone mill of smearing, and it comprises mill 1 and grinds 2 down.Last mill 1 and following mill 2 can relatively rotate.In the present embodiment, following mill 2 maintains static, on grind 1 with respect under grind 2 and rotate.Shown in Fig. 1,2 and 4, following mill 2 has a newel 6, on grind 1 a centre bore 7 arranged.Newel 6 inserts in the centre bore 7, and mill 1 can be rotated relative to grinding 2 down.

Last mill 1 has relative abradant surface separately with following mill 2.At least be formed with recessed cavity 4 at the abradant surface that grinds 2 down.In a preferred embodiment, on grind on 1 the abradant surface and also be formed with recessed cavity 3.The

female cavity

3,4 is a dome shape.The radius of curvature of recessed cavity can equate.Perhaps, in embodiment as shown in Figure 1, the radius of curvature of the described upward recessed cavity 3 of mill 1 is less than the described radius of curvature of the recessed cavity 4 of mill 2 down.Therefore, from Fig. 1, both cross sections of constituting of the recessed cavity of the described recessed cavity 3 of going up mill and described mill down 4 are and laterally have two tips, vertically have the shape of two outer convex arcs up and down.

In another embodiment, the described radius of curvature that goes up the recessed cavity 3 ' of mill 1 also can be greater than the described radius of curvature of the recessed cavity 4 ' of mill 2 down, as shown in Figure 6.

In the utility model, tealeaves is along with relatively rotating of grinding up and down, bit by bit enters stone mill central authorities from the space between newel 6 and the centre bore 7, material is not set in addition enters the hole.

Shown in Fig. 1,3,5, the abradant surface edge 10 of the described abradant surface edge 10 of going up mill and described mill down for smooth and mutually driving fit be in the same place, the radial width of driving fit portion be radius 1/5 or below.

In addition, the outer surface 21 of following mill 2 can be processed into smooth, in order to avoid adhere to tea-leaf power.In another preferred embodiment, on grind 1 outer surface 11 and also can be processed into smooth.

The foregoing description is non-limiting the utility model for illustration purpose just.Those skilled in the art can change embodiment under the situation that does not break away from scope and spirit of the present utility model or revise.
