Definitions

  • the present invention relates to a domestic soybean milk/juice extractor, and more particularly to a soymilk/juice extractor having a milling function.
  • Food processors such as soymilk, juicer/juice extractor, blender and other small white household appliances are an important branch of the home appliance industry. In recent years, they have become a hot spot in the global home appliance market, because they are convenient and fast to use, and in line with China. People's eating habits are increasingly favored by domestic consumers. There are three basic technologies for food processing machines such as soymilk machines, juicers, and blenders:
  • Omega metal tools will inevitably have problems such as rust and blade passivation
  • the metal knife is easy to generate heat during work, and the processed food is easy to stick to the metal blade, which is difficult to clean, especially the heating soymilk machine is more likely to make the food stick to the metal blade when heated;
  • Metal knives can easily breed bacteria due to the micropores on the surface and easily form odor or metallic taste, affecting taste, and also produce chemical reactions when in contact with foods such as fruits, affecting the color of food, even in the grinding and polishing. At the same time, a small amount of heavy metals will precipitate, which will have certain adverse effects on the health of the human body.
  • Soymilk the existing soya-bean milk machine is not a soy milk making tool in the traditional sense. Because the traditional soymilk processing technology is realized by manually grinding the soybeans with stone grinding tools, the types of stone grinding are generally classified into wet grinding, dry grinding, oil grinding, sauce grinding, etc., and the wet grinding is transmitted.
  • a special tool for making soy milk that is, the soybeans to be processed are soaked in water and placed in a gap between a pair of grinding discs (including the upper disc 36 and the lower disc 37), and the upper disc 36 and the lower disc 37 are on the circumference of the grinding edge. Each has a divergent grinding tooth 38 (see Fig. 1).
  • the length of the upper disc 36 grinding teeth 38 is often smaller than the length of the lower disc 36 grinding teeth 38.
  • the grinding teeth 38 can be divided into eight teeth and eight teeth. (See Fig. 1), the ten-square four-tooth and the ten-square six-tooth, etc.
  • a proper amount of water is added to the inlet, and the pair of interacting grinding discs exerts a positive pressure on the soybean while the relative movement is dislocated, and
  • the grinding action of the grinding teeth on the soybeans causes the soybeans to be pulverized and slurried.
  • the milling process includes various compounding actions such as extrusion, pressing, mashing, twisting, screwing and grinding.
  • the advantage of the stone mill milled soybean milk is that it has a rich aroma and a good taste.
  • the speed of the traditional human stone grinding is about 4 ⁇ 7 rpm, and the low-speed pulping can make it in the slurry.
  • the soy protein is in full contact with the air to promote the full oxidation of the protein.
  • the slower the rotation speed the better the soymilk is. Therefore, the soymilk produced by the traditional stone mill has a strong aroma and aroma is overflowing; then the soybean milk is filtered and the bean dregs are wrapped with cotton cloth. Pressed, the soymilk made is tender and smooth, and has a good taste.
  • the soybeans are powdered or granulated while being stirred and heated, and replaced by simple pulverization and extrusion, in the soybean milk.
  • Containing a large amount of bean dregs powder, coupled with the speed of the tool in the soymilk machine is much higher than the traditional stone grinding speed (more than 10,000 revolutions per minute), it will destroy some nutrients in the soy milk, and the nutrient extraction rate in the beans is lower. Therefore, the soymilk made is very different from traditional stone milled soy milk in terms of flavor, taste and nutritional value.
  • the traditional stone milled soymilk is superior to the existing one in taste, taste and nutritional value.
  • the blade of the agitated soya-bean milk machine is powdered with soy milk.

  • the above-mentioned juicer has the defects that: since the body of the screw 200 is a bamboo shoot-shaped structure with a small both ends and a large middle portion, the gap between the screw body and the mesh cylinder 300 correspondingly forms a larger material with a larger gap in the upper middle section. a crushing point segment f 2 having a smallest gap at a middle point of the broken grain segment, and a slurry separation portion f 3 having a slightly increased gap at a lower end portion, wherein the gap of the broken particle portion gradually becomes smaller from top to bottom.

  • the increased pulp residue separation section at the section which is processed by pressing and pulverizing the foodstuff, does not have a processing method similar to the conventional manual grinding, and therefore, although the screw adopts a slow rotation, due to the lack of a grinding process, Therefore, the aroma and taste of the soymilk still have a significant gap with the traditional stone-milled soymilk; moreover, because of the lack of milling process, the grain of the ingredients is larger, and the rotating brush 400 is required to be stuck in the mesh tube.

Description

一种具有碾磨功能的豆浆 /榨汁机
【技术领域】 本发明涉及一种家用豆浆 /搾汁机， 特别是涉及一种具有碾磨功能的豆浆 /搾汁机。
【背景技术】 食物处理器如豆浆机、果汁机 /搾汁机、搅拌机等白色小家电是家电产业的 一个重要分支， 近年来已成为全球家电市场的热点， 因其使用方便快捷， 又 符合中国人饮食习惯而越来越受国内消费者青睐。 现有的豆浆机、 搾汁机、 搅拌机之类的食品加工机的核心技术大致有以下三种：
①利用金属刀具高速旋转， 将食料打碎。 如现有的大部分豆浆机和食品 加工机都是采用这种搅拌式的食品加工机等；
②采用食料与表面冲出很多刨孔的金属刨刀片间的相对运动， 将食料加 工成丝状或粉碎， 并利用离心力使汁渣分离。 如： 刨刀式搾汁机等；
③利用螺旋杆把食料推进到一个小空间， 在空间的端部放置金属滤网， 利用挤压将食料通过滤网孔挤出； 或放置一组可相对运动的刀具， 剪切食料， 达到粉碎和搾汁的目的。 如： 螺杆式搾汁机、 绞肉机等。
上述第①、 ②点所述技术的不足之处在于：
ω金属刀具不可避免的会出现生锈、 刀刃钝化等问题；
(2)金属刀在工作时容易发热， 加工后的食物容易与金属刀片粘黏， 造成 不易清洗的缺点， 特别是加热类豆浆机更容易使食物在加热时与金属刀片粘 黏；
(3)金属刀会因其表面的微孔容易滋生细菌并且容易形成异味或金属味， 影响口味， 还会在与水果等食物接触时产生化学反应， 影响食物的色质， 甚 至在搅拌打磨的同时会有少量的重金属析出， 给人体的健康带来一定的不利 影响。
而对于豆浆机而言， 现有的豆浆机都不能算是传统意义上的豆浆制作工 具。 因为传统的豆浆加工工艺是采用石磨工具手工对黄豆进行碾磨出浆来实 现的， 石磨的类型一般分为湿磨、 干磨、 油磨、 酱磨等， 而其中的湿磨是传 统制作豆浆的专用工具， 即是将要加工的黄豆泡水后放入一对磨盘 （包括上 盘 36和下盘 37 ) 之间的间隙中， 上盘 36和下盘 37对磨面边缘圆周上均具 有呈发散状的磨齿 38 (参见图 1 )， 上盘 36磨齿 38的长度往往小于下盘 36 磨齿 38的长度， 根据不同碾磨的需要， 磨齿 38可分为八方八齿（参见图 1 )、 十方四齿及十方六齿等， 在转动磨盘的过程中向入料口适量加水， 通过这一 对相互作用的磨盘对黄豆施加正压力的同时相对移动错位， 加之磨齿对黄豆 的碾磨作用， 使黄豆粉碎出浆， 碾磨过程包括挤、 压、 揉、 搓、 拧、 磨等多 种复合作用。 石磨碾磨出的豆浆优势在于香味浓郁， 口感好。
研究发现， 决定香味浓郁的重要因素与石磨低转速的碾磨过程有直接的 关系， 传统的人力石磨转速大约在 4〜7 转 /分的范围内， 低速制浆能使浆汁 中的豆蛋白与空气充分地接触， 从而促进蛋白质的充分氧化， 转速越慢豆浆 越好吃， 故传统石磨制出的豆浆有浓郁的香味并且香气四溢； 再用棉布对豆 浆进行过滤及包裹豆渣进行压搾， 所制豆浆的细嫩幼滑， 口感甚佳。
而现有的豆浆机大多数都是采用上述第①点的搅拌式加工工艺： 即将黄 豆打成粉状或小颗粒状同时加以搅拌、 加热， 用简单的粉碎和挤压代替碾磨， 豆浆中含有大量的豆渣粉粒， 再加上豆浆机中刀具转速远高于传统石磨转速 (每分钟超过 1万转)， 会破坏豆浆中某些营养成分， 且豆中的营养成份提取率 较低， 因此做出来的豆浆无论在香味、 口感， 还是营养价值上都与传统石磨 豆浆有着天壤之别， 传统的石磨制出的豆浆在味感、 口感和营养价值上均优 于现有的搅拌式豆浆机的刀片打粉豆浆， 而且， 上述①所述技术应用于的豆 浆机不存在浆渣分离段， 一般是浆渣混合形态， 不仅影响口感， 而且不利于 人体对营养成分的吸收。 另外， 现有豆浆机在高速旋转时发生抖动， 进而会 产生较大的噪音。
上述第③点所述的技术应用于豆浆机上的很少， 但中国专利申请 200780001269. X公开了一种 《搾汁机》 属于采用这类技术的搾汁 /豆浆机， 如图 1、 2所示， 它包括一对竖向设置且嵌装在一起的同心螺杆 200和网孔筒 300， 其中， 螺杆 200表面的螺纹从上至下其高度从大变小， 网孔筒 300内表 面具有磨片， 食材从上方进入网孔筒与螺杆螺纹间隙中， 当螺杆旋转时就会 对该间隙中的食材进行挤压和粉碎， 在上述过程中产生的汁液分别通过网孔 筒上、 下两处的滤网 （分别为应变网 320和压搾网 330 ) 穿出网孔筒并通过 汁液出口端口排出， 而残渣则通过残渣出口端口 570排出。
上述搾汁机的缺陷在于： 由于螺杆 200 的本体为两端较小、 中间大的笋 形结构， 而螺杆本体与网孔筒 300之间的间隙就相应地形成了上中段间隙较 大的引料破粒段 中下点处间隙最小的粉碎点段 f2， 及下端段间隙又略为 增大的浆渣分离段 f3， 其中， 所述破粒段 ^的间隙从上至下逐渐变小， 至所 述粉碎点段时其间隙縮至最小， 使得食材进入该加工腔体内从上至下依次经 过引料、 破粒、 粉碎阶段后即进入对应于网孔筒下部滤网处的间隙相对于粉 碎段处增大的浆渣分离段， 其对食材的加工应该是挤搾和粉碎， 不具有类似 传统手工碾磨的加工方式， 因此， 尽管螺杆采用了慢速转动， 但由于缺乏碾 磨过程， 故豆浆的香味和口感仍与传统石磨加工的豆浆有明显的差距； 而且， 由于它缺乏碾磨的过程， 导致食材的颗粒较大， 需要旋转刷 400将卡在网孔 筒滤网上的大颗粒食材刷落在搾出的汁液中， 否则， 滤网会很快堵塞而无法 出浆， 这样会增加豆浆的含渣量， 影响汁液的细滑度。
【发明内容】 本发明的目的在于提供一种结构简单、 所制食材浆汁能保留食材本身的香 味、 口感细嫩幼滑、 营养成分丰富的具有碾磨功能的豆浆 /搾汁机， 可实现传统 石磨的碾磨效果， 能够对被加工食材进行揉、 搓、 压、 挤、 拧、 磨等多种复合作 用， 以达到碾磨出浆的目的。
本发明的上述目的通过如下的技术方案来实现： 一种具有碾磨功能的豆浆 /搾 汁机， 包括上座体与下座体， 所述下座体内设有驱动机构， 所述上座体包括壳体、 上盖及竖向设置于壳体内的一对同心转子和定子， 所述定子嵌套在所述转子 上， 所述转子包括转子本体及分布于该本体外表面上的螺纹凸筋和与驱动机 构连接的驱动连接结构， 所述定子的上部与下部具有环形滤网， 两滤网之间 内壁上设有竖向的磨片； 所述壳体的底部开有出液口与出渣口， 其特征在于 所述转子上的螺纹凸筋至少为两个， 且均衡分布在转子本体外表面上， 所述 转子的螺纹凸筋与定子内壁之间留有转动间隙， 所述转子本体中上部为上小 下大的回转体， 使得转子本体中上部与定子之间的间隙自上而下逐渐縮小， 其中， 转子本体上部对应于定子上部过滤网处的间隙最大， 是进料后对食材 进行加工的破粒段， 转子本体中部对应于定子磨片中上部处的间隙中等， 是对食 材进一步粉碎，转子本体中部以下对应于定子磨片下部处的间隙縮小至 lmm以内， 是对食材的碾磨段， 即在该段中对食材实施揉、 搓、 压、 挤、 拧、 磨等多种复合 加工作用， 在碾磨段下方转子对应定子下部滤网处为浆渣分离段， 通过转子在定 子内的慢速转动， 依靠所述间隙的不同对食材自上而下进行引料、破粒、粉碎、 碾磨、 浆渣分离， 最后出浆。
本发明转子的螺纹凸筋均衡分布在转子本体上， 使得转子可稳定转动， 由于 转子是低速转动， 转速不超过 100转 /分， 故不会发生转子抖动的现象， 噪音也相 对大大地减少； 食材经过引料、 破粒、 粉碎、 碾磨、 出浆过程， 其中， 碾磨过程 类似于传统石磨对食材的碾磨加工， 可将食材碾磨的更细腻， 香味浓郁， 口感细 嫩幼滑， 营养成分析出更高； 食材的大部分营养成分被碾磨出来， 能够增加人体 对营养成分的吸收率； 另外， 由于经过上述的碾磨过程， 所制汁液的细滑度高， 能够保持定子的网孔畅通， 因此无需采用现有技术中的旋转刷， 就能保持一定的 出浆、 出渣率。
作为本发明的优选实施方式， 所述转子本体中部对应于定子磨片下部处的 间隙为碾磨间隙， 该碾磨间隙的宽度为 0.5mm D 0.8mm; 该碾磨间隙的长度 为 10mm L3 25mm。
作为本发明的一种改进， 所述转子位于碾磨段部位的外表面圆周处采用 纳米陶瓷材料制成转子纳米陶瓷环； 所述定子相对应的内表面圆周处采用纳 米陶瓷材料制成定子纳米陶瓷环， 食材进入所述碾磨段间隙时在转子纳米陶 瓷环与定子纳米陶瓷环之间低速碾磨。 利用纳米陶瓷材料本身无微孔、 高致密 性及不含镍、 铬等重金属元素， 耐酸碱、 不易生锈变色， 不会与食物发生任何化 学反应， 无任何有毒物质析出， 对食材的吸附力较小的材料特质， 以便更有利于 保持食物的原味， 更便于进行清洗； 而且还能有效抑制细菌的滋长， 长期使用有 益身体健康； 此外， 陶瓷硬度、 耐磨度远高于传统金属， 性能长期稳定且分解回 收率高， 既能有效提高本发明的使用寿命， 又能大幅减少产品报废时对环境造成 的污染。
作为本发明的一种实施方式， 所述具有纳米陶瓷环的转子由上转子、 转 子纳米陶瓷环和下转子组合为一体， 在所述下转子的顶部侧缘上设有环形安 装槽， 所述转子纳米陶瓷环位于所述安装槽中， 所述上转子结合于所述下转 子的顶面上。
作为本发明的一种实施方式， 所述壳体为筒形， 所述上盖设于所述壳体 的顶部上， 所述上盖具有进料口， 所述转子的中心部位具有转轴， 该转轴的 上端由上盖定位； 所述进料口与所述转子的转轴偏心设置， 所述进料口通过 转子的螺旋凸筋与所述转子、 定子之间的间隙相通。
本发明还可以做以下改进， 为避免浆汁渗漏进入转子与驱动机构的连接 结构中， 滋生细菌或者引起金属零件生锈等问题， 在壳体底面与转子底面设 置了防渗水结构， 利用水向低处流的规律而将所述壳体底面的中部设计为高 于转子本体外缘底端与壳体底面相接触的平面的凸台形， 所述凸台形中部底 面中心处开有通孔， 以便让所述驱动连接结构通过； 相应地， 在转子底面对 应于所述壳体底面的凸台形中部底面处也设置有形状相合的内凹孔， 使转子 底面与所覆盖的壳体底面相吻合， 并且两者之间设置有至少一道密封结构， 如在壳体底面中心通孔的部位套有横截面为 u字形的密封圈， 其 u字形槽套 装在所述通孔孔缘上。 而设置密封结构则可进一步防止浆汁从该通孔与所述 驱动连接结构之间的间隙进入。
作为本发明防渗水结构的进一步改进， 所述凸台形中部底面可以加设至 少一级圆周台阶， 以增加渗水防线。 另外， 还可以进一步在至少一个台阶的 阶面上设置至少一条环形条状凸缘作为进一步的渗水防线， 相应地， 所述转 子的底面也具有环形凹槽， 所述凸缘卡于所述凹槽中。
为进一步加强本发明的防渗水结构， 在所述壳体底部外缘具有环形的导 向槽， 所述转子底面边缘设有突起的导向环， 所述导向环嵌入所述壳体导向 槽中。 导向槽与导向环配合构成***的密封结构， 用于防止浆汁从转子与壳 体底面之间的间隙进入。
作为本发明的一种实施方式， 所述浆渣分离段处的转子对应定子下部滤网 处的间隙为浆渣分离间隙， 该浆渣分离间隙由上至下逐渐增大， 形成环形的喇叭 口形状。
本发明所述浆渣分离间隙的宽度为 1.0mm H 2.0mm; 该浆渣分离间隙的 长度为 10mm L4 25mm。
与现有技术相比， 本发明具有如下显著的效果：
ω本发明转子的螺纹凸筋至少是两条或者两条以上， 它们均衡地分布在转子 本体表面上， 使得转子可稳定转动， 不会发生转子抖动的现象， 噪音也能大大地 减小。 (2)本发明除了转子本体中上部与定子之间形成的间隙自上而下縮小外， 还增 加了转子本体中部以下一段与定子磨片部之间的间隙不超过 1mm的碾磨段， 使得 食材进入本发明的加工腔体内不但经过破粒段、 粉碎段、 浆渣分离段的加工， 而 且， 食材在粉碎后会进一步经过碾磨加工， 该碾磨段的低速碾磨过程类似于传统 石磨碾磨， 这种碾磨过程对食材实施揉、 搓、 压、 挤、 拧、 磨等多种复合加工作 用， 可将食材碾磨得更细腻， 营养成分析出更高； 食材的大部分营养成分被碾磨 出来， 能够增加人体对营养成分的吸收率。
(3)由于本发明食材经过碾磨过程， 所制食材浆汁的细滑度高， 不会堵塞定子 上的网孔， 可保持定子的网孔畅通， 因此， 与现有技术相比， 本发明可省去旋转 刷， 结构比较简单； 同时， 本发明能够保持一定的出浆、 出渣率。
(4)本发明推荐转子与定子在碾磨段部位采用纳米陶瓷材料， 其具有耐磨损、 易清洁、 抑制细菌繁殖、 对食材的低吸附性等优点， 可大幅提高产品性能及耐用 度， 控制金属刀片有毒物质的析出， 性能长期稳定且分解回收率高， 容易清洗， 可大幅减少产品报废时对环境造成的污染。
(5)本发明可以提取食材中更多的营养成分， 提升口感的同时使营养更容易被 人体吸收， 实用性强， 适应性广， 成本相对低廉； 同时又具备方便、 快捷、 环保 的特点。
