Description

用于含脂肪产品的注射成型系统
本发明涉及用于模具中的含脂肪产品的注射成型系统,其适于提供成形的固体。
具体地,本发明的系统可以通过复制所述模具和半壳体的表面光洁度和形状而应用于具有相对薄的厚度的产品的生产,通常成形为壳体,并且可能适合于用可食用组合物(成分)填充。
本领域中已知一种注射成型系统,该系统配备有成形为壳体的由两个半壳体组成的模具,这两个半壳体相互限定成型凹部;所述成型凹部在其顶部上具有适于将巧克力加压注入模具内的开口孔。然后,所述模具被从所述系统移除并被输送通过冷却室。一离开冷却室,所述模具就被打开或排空,从而允许移除固化的巧克力。
所述系统具有多个缺点,主要是由于为了完全填充模具需要使用大量时间;而且,所述固化产品的移除在模具已经在冷却室内被驱动之后发生,使得必须在等待单个模具的冷却时间后才能够进行新的成型过程,或者可能必须为系统提供另外的、相对昂贵的模具,以便减少第一单个模具的冷却等待时间。此外,如果与其他已知系统相比,因为所述系统以非常低的注射压力值操作(这有损该系统的产量),所述系统不能保证良好的成型产量。
还已知一种用于生产巧克力固体的设备,该设备装备有复合模具和注射工具。熔化巧克力通过所述注射工具在压力下被注入到由两个半壳体组成并配备有合适的注射孔的凹部中;而且,所述设备配备有冷却通道,冷却液体在所述冷却通道内部循环,并且所述设备配备有两个注射通道,所述注射通道的外部涂覆有隔离层并且在底部配备有喷嘴。所述喷嘴配备有放置在杆阀中的加热筒,并且所述喷嘴也涂覆有隔离层,诸如,例如EP0017104中所公开的。
清楚的是,主要是由于所公开的设备配备的冷却通道的尺寸,导致生产所公开的设备多么复杂并且多么高度累赘。此外,所述冷却通道的存在允许减少冷却以及随后从所述模具中移除所述巧克力固体所需的时间,但是其不能保证所述模具的整个凹部的均匀冷却,以及在所形成的固体中的巧克力重量的精确调节,而这可能有损其产量。
还已知一种成型系统,如例如在WO9412046中公开的,所述成型系统主要由三个部件组成:第一部件涉及注射通道,第二部件和第三部件由模具的两个半壳体给出。所述部件具有的形状和尺寸允许它们相互连接,以及使熔化巧克力能够注入到由两个半壳体限定的凹部内。特别地,这三个部件由不同的材料组成,取决于在差异模式下在熔融的巧克力沿着所述注射通道从注射点到所述成型凹部的通行期间使得能够实现热传递的必要导热性。
最后,已知一种注射成型系统,所述注射成型系统配备有内部热通道和/或次级通道,适于使熔化的产品能够在短时间内且以低的压力损失传送。所述类型系统的功能性特征显著地取决于所述热通道的设计,具体地取决于它们的结构性特征,诸如尺寸、直径等,这显著地影响成型固体的最终特征。
从现有技术的分析中清楚的是,现有的注射成型系统不允许功能性冷却和由所述模具固化的产品的最佳分离。此外,所述系统不允许在熔化材料沿着所述注射通道从所述注射点到所述模具凹部中的进入点的通行期间对产品温度进行检查。
因此,本发明的目的是通过提供一种注射成型系统来解决上述现有技术问题,所述注射成型系统能够优化含脂肪产品的成形固体的生产。
本发明的另一目的是提供一种注射成型系统,该注射成型系统能够在含脂肪产品在所述注射成型系统内部流动期间查证所述含脂肪产品的温度。
此外,本发明的目的是提供一种适于调节所述产品的冷却步骤从而确保均匀冷却的注射成型系统。
正如将从以下描述中得到的,通过权利要求1所述的含脂肪产品的注射成型系统获得本发明的上述和其他目的和优点。本发明的优选实施例和不平凡的变化是从属权利要求的主题。
所有所附权利要求旨在是本说明书的组成部分。

-图1示出了根据本发明的注射成型系统的优选实施例的截面图;和
-图2示出了根据本发明的注射成型系统的主要部件的截面图。
参考图1,可以注意到,模具9中的含脂肪产品(诸如,例如具有或不具有固体包含物的熔化巧克力或其他类似物)的注射成型系统1装配有至少一个注射装置3,所述注射装置诸如,例如具有可变面积的管道或者喷嘴或其他合适物,有利地会聚且具有平截头圆锥体部段;含脂肪产品在熔化状态下在具有内部校准孔的至少一个注射通道2中在注射装置3内部从较大直径到较小直径滑动。
上述系统1基本上包括:
-至少一个加热元件5,布置在所述注射装置3内与所述注射通道2平行的圆柱形腔室内,所述加热元件5(诸如,例如具有装甲火花塞的电阻或主控流型(Masterflow type)的高效电阻,或带式电阻)有利地呈现圆柱形形状并且确保均匀的热分布:完全明白的是,所述加热元件5可以由适于达到上述目的的任何其他装置组成。此外,加热元件5可能装配有至少一个热调节元件,所述热调节元件放置在所述加热元件5的远端部分中,从而允许对产品温度的精确检测和调节;
-所述模具9的至少一个阳(male,凸)半壳体8(诸如,例如具有适当形状的冲头或其他类似物),所述半壳体例如通过螺栓型接合(junction)或化学紧固方式连接到至少一个冷却支撑装置7,所述半壳体8装配有至少一个内部空间,适于使得能够实现所述注射装置3与所述半壳体8的至少一个耦接。
所述半壳体8还装配有至少一个热隔离装置10,诸如,例如由绝热材料制成的透热衬套。热隔离装置10紧固到所述半壳体8的内部空间的至少一个内表面,并与所述注射装置3的所述注射通道2的至少一个下端部连接,以便防止所述注射通道3的下端部加热所述半壳体8。
具体地,所述半壳体8适于与至少一个阴(female,凸)半壳体9配合,从而限定至少一个容积16,所述容积16适于容纳和包含由所述注射装置3注射的含脂肪产品,并且适于将期望的形状压印到所述产品上。
所述注射装置3通过至少一个受热的接合装置6(诸如,例如平面凸缘、台阶部、金属垫圈、简单的腔室或双腔室)紧固到所述含脂肪产品的至少一个输送装置17,从而允许输送装置17所装配的至少一个传导元件19与所述注射装置3的注射通道2的至少一个上端部之间的线性耦接;此外,所述注射装置3可以装配有至少一个第一密封元件4(诸如,例如由硅酮或其他材料制成的静态密封垫圈、环面或方形部段),从而确保含脂肪产品不会在所述传导元件19与所述注射通道2的所述上端部之间的耦接部附近泄漏。
此外,通过将所述注射装置3的所述注射通道2的下端部紧固在所述半壳体8的衬套10中而将所述注射装置3与所述半壳体8耦接,所述注射装置3与所述半壳体8之间的耦接限定了容积11a,该容积适于将气体隔离系统的调节装置12插入所述半壳体8的内部空间中。
冷却支撑装置7(诸如,例如凸缘或板,或其他适合物)装配有至少一个中心孔,所述中心孔适于使得所述注射装置3能够插入所述半壳体8的内部空间中,以及使得所述调节装置12能够插入容积11a内;此外,所述冷却支撑装置7装配有至少两个通孔15,所述通孔也适合于与所述注射装置3平行地布置。
此外,根据本发明的所述系统1可以包括至少一个气体隔离系统,该气体隔离系统包括用于使至少一种隔离气体(优选干燥空气)进入的至少一个用于进入的装置11(诸如,例如进入嘴或其他类似物),和至少一个调节装置12(诸如,例如挡板或其他类似物),所述调节装置12通过机械、化学或其他合适的紧固方式连接到受热的接合装置6的表面。
所述气体隔离系统适于使至少一种隔离气体(诸如,例如干燥空气)能够通过用于进入的装置11进入到所述注射装置3与所述半壳体8之间,也可能进入容积11a的内部,从而在由冷却支撑装置7冷却的半壳体8与由加热元件5加热的注射装置3之间引起热隔离,并且之后通过所述调节装置12,在运送区13中输送隔离气体。之后,通过调节装置12,所述隔离气体经由冷却支撑装置7的一个或多个通孔15从所述区域13朝向所述模具9流出。
此外,所述气体隔离系统允许调节和控制所述半壳体8和所述模具9的露点(dewpoint),直至获得所述成形的固体。
另外,所述冷却支撑装置7和所述受热的接合装置6限定了通过至少一个第二密封元件14(诸如,例如由硅酮或者适用于此目的的其他材料制成的垫圈、环面或方形部段)相互连接的运送区13。
