Description
本發明涉及植物顆粒的研磨技術,特別是指一種研磨刀具,適用於咖啡豆的研磨領域。 The invention relates to the grinding technology of plant particles, in particular to a grinding tool, which is suitable for the grinding field of coffee beans.
飲用咖啡的人口相當多,一些人會飲用現場製作的咖啡,某些人則喜歡選購咖啡豆,親手做出濃郁香醇的咖啡。無論是哪一種咖啡,都是採用研磨的模式,將咖啡豆磨成不同大小的顆粒、碎片或粉末,添加熱水沖泡出一杯熱咖啡。 There are quite a lot of people drinking coffee. Some people drink coffee made on the spot. Some people like to buy coffee beans and make rich coffee. No matter which type of coffee, it is a grinding mode, grinding coffee beans into granules, chips or powder of different sizes, adding hot water to brew a cup of hot coffee.
影響咖啡的因素相當多,例如不同品種的咖啡豆,沖泡出口味不同的咖啡。當然,顆粒的大小攸關萃取的時效,影響即溶的速率甚鉅,只有選擇好的磨咖啡豆機,用優異的研磨刀具來改變咖啡豆磨成顆粒的大小。 There are quite a number of factors affecting coffee, such as different types of coffee beans, brewing coffee with different tastes. Of course, the size of the particles is related to the aging time, and the rate of instant dissolution is very large. Only the selected coffee bean machine is used, and the excellent grinding tool is used to change the size of the coffee beans to be granulated.
關於研磨刀具的種類相當多,譬如螺旋槳式、平行式(Flat Burrs)、錐型(ConicaI Burrs)或臼齒式磨盤(亦稱鬼齒刀盤)等。 There are quite a few types of grinding tools, such as a propeller type, a flat type (Flat Burrs), a cone type (ConicaI Burrs) or a dent type grinding disc (also known as a ghost tooth cutter disc).
其中,該平行式研磨刀具的時間比臼齒式磨盤短,卻會將咖啡豆磨成碎片,不利於水的萃取。該臼齒式磨盤研磨時間長,容易讓顆粒受熱變質,影響到咖啡的口味。 Among them, the parallel grinding tool is shorter than the molar grinding disc, but the coffee beans are ground into pieces, which is not conducive to water extraction. The toothed grinding disc has a long grinding time and is easy to cause the particles to be deteriorated by heat, which affects the taste of the coffee.
因此,如何讓研磨刀具擁有平行與臼齒二模式的優點,就成為本發明亟待解決的課題。 Therefore, how to make the grinding tool have the advantages of the parallel and the caries two modes has become an urgent problem to be solved by the present invention.
鑒於此,本發明提供新的研磨刀具,其主要目的在於:融合平行與臼齒二模式的優點於一身,在比傳統式研磨刀具更短的時間磨出所 需大小的顆粒,相對提昇咖啡的良率。 In view of this, the present invention provides a new grinding tool whose main purpose is to combine the advantages of the parallel and the two-toothed mode, and to grind the machine in a shorter time than the conventional grinding tool. The size of the particles is required to increase the yield of the coffee.
緣於上述目的之達成,本發明的研磨刀具由一第一刀盤與一第二刀盤組成,該第二刀盤結構與第一刀盤大致相同。 For the above purposes, the grinding tool of the present invention consists of a first cutter head and a second cutter disc, the second cutter disc structure being substantially identical to the first cutter disc.
該第一刀盤為圓環,其擁有一研磨面,該研磨面突出多圈齒:最內圈的齒界定為平齒,這些平齒圍繞第一刀盤的內環面,在相鄰二平齒之間形成一齒溝,每個平齒有一平的齒頂,該齒頂二側分別銜接一切削面與一齒背;最外圈的齒視為臼齒,這些臼齒靠近第一刀盤的外環面,在相鄰二臼齒之間形成一齒谷,每個臼齒有一呈銳角設計的齒尖,該齒尖沿圓周方向延伸。 The first cutter head is a ring having a grinding surface that protrudes a plurality of teeth: the teeth of the innermost ring are defined as flat teeth, and the flat teeth surround the inner ring surface of the first cutter head, adjacent to the second A tooth groove is formed between the flat teeth, each flat tooth has a flat tooth top, and the two sides of the tooth top respectively engage a cutting surface and a tooth back; the teeth of the outermost ring are regarded as caries, and the teeth are close to the first cutter head. The outer annulus forms a valley between adjacent two molars, each of which has an acutely designed tooth tip extending in the circumferential direction.
其中,每個刀盤的半徑相交於平齒的切削面形成一角度,該角度是5°~20°。 Wherein, the radius of each cutter disc intersects the cutting surface of the flat teeth to form an angle of 5°-20°.
該平齒的齒頂是斜的,其與一條平行於刀盤直徑且虛擬的水平線相交而形成一夾角,該夾角是5°~25°。 The crest of the flat tooth is oblique and intersects with a virtual horizontal line parallel to the diameter of the cutterhead to form an included angle of 5° to 25°.
該平齒的切削面相交於其他的平齒的齒背而形成一齒溝角,該齒溝角是45°~65°。 The cutting faces of the flat teeth intersect with the backs of the other flat teeth to form a pitch angle of 45° to 65°.
在二刀盤間隔一定距離併排時,二刀盤的研磨面彼此相向,二研磨面的臼齒相互錯開且平齒的方向相反,對通過二刀盤之間的咖啡豆執行研磨作業。 When the two cutter discs are arranged side by side at a certain distance, the grinding surfaces of the two cutter discs face each other, the teeth of the two grinding surfaces are offset from each other and the flat teeth are opposite in direction, and the grinding operation is performed on the coffee beans passing between the two cutter discs.
如此,每個刀盤在結構設計上,將平行與臼齒二模式的優點融合於一身,使研磨刀具能短時間磨出所需大小的顆粒,相對提昇咖啡的良率。 In this way, each cutterhead is structurally designed to combine the advantages of the parallel and the two modes of the molars, so that the abrasive cutter can grind the particles of the required size in a short time, and relatively improve the yield of the coffee.
接著,基於圖式詳述相關的實施例,說明採用之技術、手段及功效,相信本發明上述目的、構造及特徵,當可由之得一深刻而具體的瞭解。 The above-described objects, structures and functions of the present invention will be described with reference to the detailed description of the embodiments.

如第1、2圖所示,闡明刀具10一較佳實施例的具體構造,是由一第一刀盤12與一第二刀盤14組成,能將咖啡豆研磨成所需大小的顆粒。 As shown in Figures 1 and 2, the specific construction of the preferred embodiment of the tool 10 is illustrated by a first cutter head 12 and a second cutter head 14 which are capable of grinding coffee beans into granules of the desired size.
所述的第一刀盤12是圓環,其二側面之一界定為研磨面16。在第2、3圖中,該研磨面16突出多圈齒,依形狀區分為平齒20和臼齒30兩種類型。在本實施例中,以第一刀盤12的圓心15為軸,這些齒圍成四圈同心圓,其中一圈是平齒20,其他三圈則是臼齒30。 The first cutter head 12 is a circular ring, one of its two sides being defined as an abrasive surface 16. In the second and third figures, the abrasive surface 16 protrudes into a plurality of teeth, and is classified into two types, the flat teeth 20 and the molars 30. In the present embodiment, with the center 15 of the first cutter head 12 as the axis, the teeth are surrounded by four concentric circles, one of which is the flat tooth 20 and the other three turns are the molars 30.
最內圈的齒界定為平齒20,這些平齒20圍繞第一刀盤12的內環面18,在相鄰二平齒20之間形成一齒溝26。每個平齒20有一齒頂28,該齒頂28是平的,其二側分別銜接一切削面22與一齒背24。 The teeth of the innermost ring are defined as flat teeth 20 which surround the inner annulus 18 of the first cutter head 12 and define a toothed groove 26 between adjacent flat teeth 20. Each of the flat teeth 20 has a tooth tip 28 which is flat and has a cutting face 22 and a tooth back 24 on each of its sides.
每個平齒20的切削面22相交於第一刀盤12的半徑17形成一角度θ 1,決定齒溝26長度幾乎到達最外圈的臼齒30。該角度θ 1以5°~20°為較佳的範圍。 The cutting face 22 of each flat tooth 20 intersects the radius 17 of the first cutter head 12 to form an angle θ1 which determines the length of the tooth groove 26 to reach the outermost ring of the molars 30. The angle θ 1 is preferably in the range of 5° to 20°.
在第4圖中,所述的齒頂28是斜的,其與一條平行於第一或第二刀盤12或14直徑且虛擬的水平線19相交,構成一範圍是5°~25°的夾角θ 2。 In Fig. 4, the crests 28 are oblique, intersecting a virtual horizontal line 19 parallel to the diameter of the first or second cutter head 12 or 14, forming an angle ranging from 5° to 25°. θ 2.
另外,每個平齒20的切削面22相交於下一個平齒20的齒背24,從而構成一決定齒溝26形狀的齒溝角θ 3。所述的齒溝角θ 3範圍,以45°~65°為佳。 In addition, the cutting face 22 of each flat tooth 20 intersects the tooth back 24 of the next flat tooth 20 to form a tooth groove angle θ 3 that determines the shape of the tooth groove 26. The range of the gullet angle θ 3 is preferably 45° to 65°.
回頭看到第2、3圖,三圈臼齒30相互錯開為佳。以最外圈的臼齒30為例,這些臼齒30靠近第一刀盤12的外環面11,在相鄰二臼齒30之間形成一齒谷34。每個臼齒20有一齒尖32,該齒尖32呈銳角設計,並沿著圓周 方向延伸。 Looking back at Figures 2 and 3, it is better that the three turns of the molars 30 are staggered from each other. Taking the outermost teeth 30 as an example, the molars 30 are adjacent to the outer annulus 11 of the first cutter head 12, and a valley 34 is formed between the adjacent second molars 30. Each of the molars 20 has a tooth tip 32 that is designed at an acute angle and along the circumference The direction extends.
至於第二刀盤14的結構或機能形狀,大致相同於第一刀盤12的構造,故不予贅述。 The structure or functional shape of the second cutter head 14 is substantially the same as that of the first cutter head 12, and therefore will not be described.
該第一、第二刀盤12、14各有一對結合部13,透過兩根如螺絲般的緊固件(圖未示)鎖入結合部13,使二刀盤12、14併排在一起。如第4圖所示,該第一、第二刀盤12、14的研磨面16彼此相向,二者相隔一定的距離。此刻,二研磨面16的臼齒30相互錯開,而且第一刀盤12與第二刀盤14的平齒20方向相反。 The first and second cutter heads 12, 14 each have a pair of joint portions 13, which are locked into the joint portion 13 by two fasteners (not shown) such as screws, so that the two cutter discs 12, 14 are arranged side by side. As shown in Fig. 4, the polishing faces 16 of the first and second cutter heads 12, 14 face each other with a certain distance therebetween. At this point, the teeth 30 of the two abrasive faces 16 are offset from each other, and the first cutter head 12 is opposite to the flat teeth 20 of the second cutter head 14.
從第2、4、5圖來看,這組刀具10配合一送料器42安裝在一磨咖啡豆機40內部。該送料器42一端連接一馬達軸44,另端結合一前蓋46,在前蓋46外部組裝一刻度式調節鈕48。 From the 2nd, 4th, and 5th views, the set of cutters 10 are mounted in a grinder of the coffee bean maker 40 in conjunction with a feeder 42. The feeder 42 is connected to a motor shaft 44 at one end and a front cover 46 at the other end, and a scale knob 48 is assembled outside the front cover 46.
當磨咖啡豆機40通電後,扭動調節鈕48對齊任一刻度,對二刀盤12、14產生調整作用,改變二研磨面16相隔的距離,達到顆粒大小的選擇功能。一般而言,刻度值愈小,顆粒體積愈大,例如1號刻度的顆粒比4號刻度的顆粒還大。 When the coffee bean machine 40 is energized, the twist knob 48 is aligned with any scale to adjust the two cutter discs 12, 14, and the distance between the two abrasive surfaces 16 is changed to achieve the particle size selection function. In general, the smaller the scale value, the larger the particle volume, for example, the particles on the 1st scale are larger than the particles on the 4th scale.
接著,該馬達軸44帶動送料器42旋轉,引導咖啡豆(圖未示)進入刀具10以內環面18圍成的軸心空間中。在重力作用下,咖啡豆通常會先落入二研磨面16內圈的平齒20之間,不是被相向二齒頂28壓碎,就是被切削面22切割成若干咖啡碎塊。這些碎塊的體積較大,在順著齒溝26滾向外環面11時,會被二刀盤12、14錯開的臼齒30磨得更微小,直到體積等於或小於顆粒預設值為止,才能通過最外圈的臼齒30而掉落磨咖啡豆機40外面。 Next, the motor shaft 44 rotates the feeder 42 to guide the coffee beans (not shown) into the axial space surrounded by the inner ring surface 18 of the tool 10. Under the action of gravity, the coffee beans usually fall between the flat teeth 20 of the inner ring of the two abrasive faces 16, not crushed by the opposing two-teeth tops 28, or are cut into a number of coffee pieces by the cutting face 22. These pieces are relatively large in volume, and when the outer ring surface 11 is rolled along the tooth groove 26, the teeth 30 which are staggered by the second cutter discs 12, 14 are ground to a smaller extent until the volume is equal to or smaller than the preset value of the particles. The outer surface of the coffee bean machine 40 can be dropped by the outermost teeth 30.
因此,刀具10在併排狀態下,對通過二刀盤12、14之間的咖啡豆執行研磨作業。 Therefore, the cutter 10 performs the grinding operation on the coffee beans passing between the two cutter discs 12, 14 in the side-by-side state.
