Description
本發明關於一種製造陶瓷濾器的方法，特別是一種製造可以反覆使用、用於沖泡茶葉、咖啡等飲品的陶瓷濾器的方法。The present invention relates to a method of manufacturing a ceramic filter, in particular to a method of manufacturing a ceramic filter that can be used repeatedly for brewing beverages such as tea and coffee.
在以往，啜飲咖啡或茗茶是一種休閒的生活方式，甚至可以說是特殊身分的體現。沖泡咖啡或茶葉往往需要特殊的工具及不少的時間，沒有一定的經濟實力或悠閒時間是難以享受的。隨著與原料產國間的貿易量增加、食品工業技術的提升，以及文化的交流，國人已經普遍接受這些提神飲料，並當成是生活中不可或缺的一部分。走在街頭上，可以不時看見人們人手一杯沖泡式咖啡或封裝（花）茶。除了時尚，很多人飲用這些飲料的目的是為了讓工作或學習更有精神與效率。In the past, sipping coffee or tea was a casual way of life, and it could even be said to be a manifestation of a special identity. Brewing coffee or tea often requires special tools and a lot of time, and it is difficult to enjoy without certain economic strength or leisure time. With the increase in trade volume with raw material producing countries, the improvement of food industry technology, and cultural exchanges, the Chinese people have generally accepted these refreshing drinks and regarded them as an indispensable part of life. Walking on the street, you can see people holding a cup of brewed coffee or encapsulated (flower) tea from time to time. In addition to fashion, many people drink these beverages to make work or study more energetic and efficient.
推動咖啡與茶的一般化消費的功臣是便利沖泡技術的普及。三合一隨身包、茶包等工具讓人們想喝飲料時就加熱水沖泡。甚至，如果人們想喝現沖研磨咖啡或現泡茶葉，也有特殊設計的掛耳式濾泡袋可以使用，可免去傳統沖泡工具的束縛卻能享受幾乎一模一樣的味道。然而，這些包裝或沖泡工具往往都是一次性的，使用完就丟棄。在人類生活開始強調永續與保育的當下，為了享受而犧牲環境與浪費資源的產品，很快會被時代潮流所掩沒。The hero of promoting the general consumption of coffee and tea is the popularization of convenient brewing technology. Three-in-one carry-on bags, tea bags and other tools allow people to make hot water when they want to drink. Even if people want to drink freshly brewed ground coffee or freshly brewed tea, there are also specially designed hanging ear follicle bags that can be used, which can avoid the shackles of traditional brewing tools but can enjoy almost the same taste. However, these packaging or brewing tools are often disposable and discarded after use. As human life begins to emphasize sustainability and conservation, products that sacrifice the environment and waste resources for enjoyment will soon be overshadowed by the trend of the times.
因此，本發明人基於在相關產業長時間的研發基礎下，提出了本專利的製造陶瓷濾器的方法。這種創新的陶瓷濾器可以用來濾泡咖啡或茶葉，可回收重複使用卻不影響飲料的風味。Therefore, the inventor proposed the method of manufacturing a ceramic filter of this patent based on long-term research and development in related industries. This innovative ceramic filter can be used to filter coffee or tea, can be recycled and reused without affecting the flavor of the beverage.

依照本發明所製作的陶瓷濾器可以用來濾泡咖啡或茶葉，可回收重複使用卻不影響飲料的風味。The ceramic filter made according to the present invention can be used to filter coffee or tea, and can be recycled and reused without affecting the flavor of the beverage.
本發明將藉由參照下列的實施方式而更具體地描述。The present invention will be described more specifically by referring to the following embodiments.
請見圖1，該圖為依照本發明的一實施例的一種製造陶瓷濾器的方法的流程圖。首先，提供一外型模具，該外型模具剖面形狀包含一陶瓷濾器燒結前粗胚的外部形狀（S01）。為了對本步驟有較佳的理解，請見圖2，該圖為該方法中所提及之一外型模具10的剖面示意圖。在圖2中，陶瓷濾器燒結前粗胚的外部形狀類似一個倒置奶嘴頭的形狀。依照本發明，未來成形的粗胚具有一開口，而該開口形成於外型模具10最上方。該粗胚的外型，為了配合沖泡咖啡或茶葉，乃採用由上方開口漸縮至下方底部的漸變設計。只要符合這種設計剖面形狀的外型模具10，都在本發明所主張的範圍內。因此，半圓球體、圓錐及前述的倒置奶嘴頭的形狀都符合前述要求。此外，燒結後的陶瓷濾器外觀是沿著其中央的一對稱軸呈立體軸對稱。從而，圖2中的示意圖乃是沿著外型模具105中對應該對稱軸任一方向對外型模具10進行剖切的剖面圖。為了方便說明，未來形成該粗胚處定義為一置料空間11。依照本發明，外型模具10最好以石膏製成，以便吸收該粗胚中部份多餘的水分。Please refer to FIG. 1, which is a flowchart of a method for manufacturing a ceramic filter according to an embodiment of the present invention. First, an external mold is provided, and the cross-sectional shape of the external mold includes the outer shape of the crude green before sintering the ceramic filter (S01). In order to have a better understanding of this step, please refer to FIG. 2, which is a schematic cross-sectional view of an
接著，請同時參閱圖3，將一混合原料20置入該外型模具10的置料空間11中，其中該混合原料20包含5-10重量份的棕鋼玉粉、5-10重量份的長石粉、5-10重量份的高嶺土礦石、5-10重量份的紫砂原礦、75-60重量份的氧化鋁礦石及5-15重量份的水分（S02）。在一實施例中，混合原料20的配比可以是7.5重量份的棕鋼玉粉、7.5重量份的長石粉、7.5重量份的高嶺土礦石、7.5重量份的紫砂原礦、65重量份的氧化鋁礦石及5重量份的水分。在另一實施中，混合原料20的配比也可以是7重量份的棕鋼玉粉、5重量份的長石粉、5重量份的高嶺土礦石、5重量份的紫砂原礦、68重量份的氧化鋁礦石及10重量份的水分。Next, referring to FIG. 3 at the same time, a mixed
水分的含量越多，混合原料20的流動性越大，但有可能會在後續步驟中被擠出或由外型模具10吸收。為了方便後續步驟施作，混合原料20的填置可以與外型模具10的上表面大致平行或略低，但必須覆蓋所有粗胚成形位置（倒置奶嘴頭外緣）。另外，混合原料20的粒徑影響了最後製成的陶瓷濾器特性。如果混合原料20的固體顆粒粒徑過大，陶瓷濾器內部容易形成較大孔洞，降低過濾咖啡粉或茶葉渣的效用；如果混合原料20的固體顆粒粒徑過小，陶瓷濾器內部過於緻密，咖啡或茶的過濾時間會變長。因此，最好以不含水分的混合原料20（烘乾後）之粒徑可完全通過60目-86微米的篩網作為混合原料20中固體顆粒粒徑的限制。The greater the water content, the greater the fluidity of the mixed
請見圖4與圖5。該發明的第3步驟為沿該外型模具10的一中央對稱軸線12快速轉動該外型模具10，並將一成型刮刀30壓入該置料空間11，以擠出多餘混合原料20並擠壓剩餘於該置料空間11中的混合原料20，從而形成粗胚21（S03）。在圖4中，中央對稱軸線12以一條點虛線表示。外型模具10可以安置於一旋轉台40上，藉由旋轉台40的轉動而轉動。成型刮刀30的外觀沿一軸心線31（以一虛線表示之）對稱，成型刮刀30受外力可沿軸心線31旋轉。也就是說，當成型刮刀30壓入置料空間11後，必然受混合原料20的摩擦力作用而轉動。這樣的作法可以免於兩者的硬接觸，使得混合原料20在未受擠壓形成粗胚21前就被刮出置料空間11，或永遠無法形成粗胚21。圖5同時繪示成型刮刀30壓入置料空間11的部分實質小於該置料空間11的大小。很明顯，這是要保留位置讓粗胚21成形。同時，中央對稱軸線12和軸心線31不重疊。成型刮刀30和旋轉台40間可以可移動的定位架連接，從而成型刮刀30壓入置料空間11的位置可以固定，不受旋轉台40轉動影響。最好，成型刮刀30可以透過一機器手臂（未繪示）來控制進出置料空間11，而該機器手臂與旋轉台40固定於同一平台上。此外，在本實施例中，成型刮刀30沿任一經過軸心線31的剖面所截出的一側曲線，形狀同該陶瓷濾器的一部分內部剖面邊線形狀。這樣的作法可以控制一部份的粗胚21的壁緣在燒結前，保持特定的厚度。Please see Figure 4 and Figure 5. The third step of the invention is to quickly rotate the
之後，重複步驟S03二次以上（S04）。也就是說，對於混合原料20的擠壓要進行至少三次。每一次擠壓，會讓粗胚21更緊緻，也讓部分水分溢出或為外型模具10的石膏吸收。因為必然有一些混合原料20會被擠出置料空間11而成為無效料，而這些混合原料20可能會黏結在外型模具10的置料空間11以外的其它地方（如圖5圓虛線框所標示的）。因此，最好在步驟S03後緊接一步驟S03’：刮除黏附在外型模具10的置料空間11外的混合原料20。亦即，每一次擠壓混合原料20後就刮除因成型刮刀30作業而黏附在外型模具10的置料空間11外的混合原料20。After that, step S03 is repeated two or more times (S04). In other words, the extrusion of the mixed
在完成步驟S04後，粗胚21基本具有一定的硬度與外觀大小。然而在燒烤前，水分還是太多，需要對該外型模具10內的粗胚21以70-80C的溫度烘乾6±0.5小時（S05）。實作上約6小時即可。烘乾器具可以使用烤燈50，調整粗胚21與烤燈50間的距離或烤燈50的輸出能量即可調整烘乾溫度。在完成烘乾作業後，自該外型模具10中取下粗胚21，以1240-1260C溫度燒烤該粗胚21 8±0.5小時（S05）。實作上約8小時即可。一般可以使用電窯進行燒烤粗胚21，溫度較好控制。最後自然冷卻燒烤後的粗胚21，即可得到製成之陶瓷濾器。After step S04 is completed, the rough blank 21 basically has a certain hardness and appearance size. However, before grilling, the moisture is still too much, and the
應注意的是，依照本發明，烘乾作業也可在取下粗胚21之後進行。因此，前述的步驟S05可改為取下外型模具10內的粗胚21並對該粗胚21以70-80C的溫度烘乾6±0.5小時（S05’ ），前述的步驟S06可改為以1240-1260C溫度燒烤該粗胚21 8±0.5小時（S06’ ）。It should be noted that, according to the present invention, the drying operation can also be performed after the
以下介紹依照本發明所製成的陶瓷濾器之用法。請見圖7，該圖繪示一陶瓷濾器22置於一杯子70上的剖面示意圖。以濾泡咖啡為例，使用時，將咖啡粉混合液60倒入陶瓷濾器22內，陶瓷濾器22就會如同濾紙一般，將咖啡62濾出，流到杯子70內。濾泡後不用的咖啡粉渣61會截留在陶瓷濾器22內表面。當然，也可以將咖啡粉先置入陶瓷濾器22內，再以熱水沖泡，同樣也可以獲得咖啡粉混合液60。清洗時，只要水洗陶瓷濾器22內表面並以熱水氣沖擊一段時間，就可以除去陶瓷濾器22內表面空隙中夾雜的咖啡粉渣61，將陶瓷濾器22回復未使用狀態，從而可以重複使用。The following describes the usage of the ceramic filter made according to the present invention. Please refer to FIG. 7, which shows a schematic cross-sectional view of a
雖然本發明已以實施方式揭露如上，然其並非用以限定本發明，任何所屬技術領域中具有通常知識者，在不脫離本發明之精神和範圍內，當可作些許之更動與潤飾，因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, The scope of protection of the present invention shall be subject to those defined by the attached patent scope.
