Description
本发明是关于食品的空气处理装置。它包括外壳,用于容纳被处理食品的细长槽。热交换器和鼓风装置,该鼓风装置用于把气流通过热交换器,向上穿过食品槽,再回到热交换器,由此完成一次气流循环。
本发明特别涉及冷冻装置,但也适合于其他的气体处理装置,例如,冷却、干燥和加热装置。对于冷冻装置,其中的热交换器是冷却盘管组。
以前所知的此类冷冻装置是采用带有多孔底板的槽,有时还用多孔底板上运行的多孔输送带,或者用后者来代替前者。确定槽底板上穿孔的尺寸时至少应使部分食品在槽内流化,这样可以提高冷冻速度和防止豌豆一类的单个食品互相冻结在一起;或者,按这种标定尺寸穿孔使食品不致流化,但用搅拌替之,这样有时就足以阻止食品互相冻结在一起,对于某些难以流化的食品,这是唯一可行的选择。
因此,已知的冷冻装置在冷冻方式上比如流化或不流化方面经常受到相当大的限制,在可处理的食品种类上也受到限制。此外,还受到单位时间处理的食品量的限制,因而不能应付食品数量较大变化。为了满足食品生产者的要求,就需要一些冷冻装置,它们可针对不同的待处理食品种类和单位时间处理量按不同的方式操作并具有不同的生产能力。
上文对冷冻装置现有技术的叙述也适于用来介绍所述类型的空气处理装置的公知技术。
本发明的目的是改进在说明书介绍中所述类型的空气处理装置,使它适应于不同方式的操作,不同的食品和不同的生产能力要求。
依照本发明,上述目的是通过使槽的一个侧壁可以侧面调整来改变槽的宽度而实现的。
在此方法中,槽的容积可以轻易地改变,从而不经改变操作方式,如流化或不流化即可将单位时间食品处理量调整到所需的量。对于较大的槽宽度,亦可采用非流化操作方式而且其单位时间处理食品的总量不少于流化操作方式,鉴于鼓风装置的最大能力,非流化操作方式在槽中一般需要较薄的食品处理床,而流化操作方式则需要较厚的床层和较小的槽宽。
如果能使鼓风机的气体流动容量可调,优选地取决于槽宽的调整来达到,那么,空气处理装置的适应性自然可以进一步提高。
故此,用本发明的一台空气处理装置即可代替几台传统类型的空气处理装置。
根据本发明的空气处理装置-优选实施例,可调侧壁向上连接于-气流通道的一块界板上。该侧壁可以与界板一起移动或相对于界板移动。在后一种情况下,侧壁通过一个或多个中间档板与界板相连,从而使侧壁能够相对槽横向移动。为使侧壁和界板之间具有相对运动性,可将一块或多块中间档板互相铰接和/或可相对运动地连接,并且/或者与侧壁和界板分别铰接。
在特别优选的实施例中,侧壁、界板和一块或多块中间档板被分别在槽的整个长度上分成几组。这些组可以各自独立地运动,这样,在整个槽的长度方向上,可有不同的槽宽。
用多孔带做底面的槽,既可以代替常规的固定多孔底板的传统槽,即在带固定不动的情况下,又可以代替多孔底板固定和有多孔带运行其上的传统槽。此外,用本发明的多孔带做槽的单独底板比使用现有技术中的多孔带更具优越性,因为现有技术中的多孔带不能精确地导引气流通过该槽,也不能很精确地调节槽底板上的压力差。
本发明尤其适合于冷冻装置型的空气处理装置。在下文中,参照附图,将对其做更详细地描述。图1是本发明冷冻装置的侧面示意图。图2和3是图1冷冻装置的截面视图,示意其两个不同的调节位置。图4A-AF,示意本发明冷冻装置中槽侧壁位移的几个基本变化情形。图5示意用于本发明冷冻装置的多孔输送带的局部。
如图1-3所示的本发明冷冻装置的实施例,它具有外壳1,侧壁2和3,端壁4和5,顶板6和底板7。端壁4和5上设有开口使带式输送机8可以横穿过外壳1,输送机上带有进料台9和出料台10。
外壳1分为若干基本相同的组件,使其可以在带式输送机8长度方向上横向延长。就此,瑞典专利申请No.9102861-3中做了较详细的说明。
如图2和3所示,外壳中有一槽11,冷却盘管组单元12和风扇13及风扇马达14。用带式输送机8的多孔输送带15做为槽11的底面。此外壳1的侧壁2作为槽11的外侧壁,附有衬里16使得表面光滑。槽11的内侧壁17垂直于带15向上伸长一个长度,该长度至少与槽11中床的最大层深一致,然后转一角度,形成一个在床上方扩大了的气体通道。气体通道限于外壳1的内侧和连于侧壁17的界板18及附加界板19-22组成的空间。界板22上设有开口以供设置风扇13的抽吸部分23,该抽吸部分与马达14一起用角钢固定在外壳1的底板7上。
冷冻装置的鼓风机,由若干风扇13组成。这些风扇沿槽11长度方向装配,每个风扇均配有马达14。类似地,冷冻装置的冷却盘管组由几组冷却盘管组单元12组成,盘管组沿槽11的长度方向布置。冷却盘管组单元12下方的外面可以布置除霜机单元25,上方则可以隔断。
依上述设计,鼓风机13产生一般按照图2和3中箭头所示方向流动的气流,就是说,沿密闭路线穿过冷却盘管组单元12,鼓风机13,向上穿过槽11,而后回到冷却盘管组单元12。侧壁17可在槽11的纵方向上做横向调节,使槽11的宽度可以连接变化,图2和3示意了可调整到的两个极限位置。为保证气体通道在侧壁17的所有位置上均完整,在侧壁17和界板18之间设置了中间档板26。板26铰接于界板18,更准确地说是铰连在板18的一个纵向边缘上,侧壁17的上部纵向边缘与中间档板26的底面作滑动连接。侧壁17和中间档板26之间的连接及板26和界板18之间的连接均按基本上气密方式装配,从而防止气流短路。
依照发明,对于任意所调槽11的宽度,鼓风机13的能力均可以变化,由此可获得不同的操作条件。举个例子,如图2所示的情形,槽11的宽度为本装置可能的最小槽宽,同时,槽11中的产品床27相对较深,对应于流化操作方式。如图3所示的情形,槽11的宽度是本装置可能的最大槽宽,同时,产品床27相对较浅,对应于非流化操作方式。
可以理解,通过改变槽11的宽度和鼓风和13的能力,就有可能适应所需的操作方式,即流化或非流化方式,和不同类食品单位时间的所需处理量。另一可变因素是带15的运动形式。即,带15既可以固定不动也可以向前运行,前者形式即为槽11的底板固定。
在流化操作方式中,气流向上穿过槽11的底板的导向决定了床层17是否能够转变成流化状态并保持该状态。现有技术中的冷冻装置,使用金属网形式的多孔带,气流的导向不足以获得稳定的流化状态。依现有技术,这需要特别尺寸的多孔固定底板。本发明使用如图5所示类型的多孔带则只单独使用多孔带就能获得稳定的流化状态。图5更具体地示意了两块相同板片28,任意数量的板片可以横着或竖着互相连接成所需长度和宽度的输送带15。依本发明板片28的整个表面上开有若干通孔29,关节接合处留有缝隙30,所述接合沿着带15纵方向将板片连接在一起。图5示意了本设计输送带的局部,使用该输送带可以以板28的厚度来得到各穿孔,使气流精确地导引通过带15形式的槽11底板成为可能,从而确保流化状态稳定。
当然,除了如图2和3所示的情况,侧壁17可以以其他的方式在槽11的横方向移动。图4A-F示意了侧壁17的几种位置变化。
如图4A所示,侧壁17固定于界板18上,此时,界板18与侧壁17一起移动。
如图4B和4D所示,侧壁17分别与槽11的底板15和界板18的伸长部分31和32以滑动连接产生位移,所述伸长部分平行于槽11的底板15。
图4C示意的实施例与图2和3示意的一样。
如图4E所示,设置一中间档板33,它与界板18铰接,并与侧壁17铰接形成可移动连接。
如图4F所示,设置中间板34和35,它们互相之间及它们与侧壁17及界板18之间均为铰接。
正如外壳1可以便利地分成若干组件,沿着槽11的长度方向,侧壁17和与之相连的板也可以分成若干相同的部分,每个部分对应一特有的组件。侧壁17的不同部分,就如同板的各部分与侧壁一起移动一样,它们也可以各自独立移动,这样,槽11在整个长度方向上可有不同的槽宽。当然了,这样做的条件是,侧壁17的不同部分,如同板的各部分与侧壁一起移动时一样,它们也具有端壁部分从而保持气流通道的完整性。
当本发明冷冻装置以流化方式操作时,某些种类的食品需要给定槽的长/宽比。槽宽的变化就迫使槽的长度有所变化,就是说,变成足以使流化发生的长度。本发明中完成这一调整的方法是设置某种类型的气密层,如设置可在多孔槽底的下面移动的连接板,尤其是用输送带形成的板。调整长度宜在冷冻装置的出料端进行,这样,穿过槽的气体循环就限制于槽长的某一部分。
显然,本发明并不限于上述冷冻装置的具体实施例,就象槽可以使用常规设计的底板一样,本发明也可以用于组件以其他方式相互装配的冷冻装置中。
最后,应当指出的是,本发明普通适用于空气处理装置,而不限于冷冻装置。
