用于将产品填充到容器中的设备和方法
Abstract:
本发明涉及一种用于将产品、特别是液体食品填充到容器中的设备和方法。在容器从入口侧到出口侧穿过设备的工作腔的同时，无菌流体、特别是无菌空气作用在穿过工作腔的容器上，以便避免污染。为了改进工作腔中的无菌氛围，本发明提出：外部管路延伸穿过工作腔，该外部管路具有用于将无菌空气引入到工作腔中的多个气体开口；并且内部管路延伸到外部管路中，该内部管路具有用于喷射清洁介质的多个开口。环形腔在内部管路和外部管路之间沿纵向方向延伸，该环形腔具有封闭端以及用于将无菌流体供应到环形腔中的入口，该入口被构造成预先限定从入口开始朝向封闭端的无菌流体在环形腔中的流动方向。环形腔的横截面面积至少分段地沿纵向方向变化，从而允许影响在环形腔中的无菌流体的静压和流速，使得实现沿着外部管路的长度的恒定压力分布以及由此从气体开口排出到工作腔中的无菌空气的均匀分布。
Abstract(English):

An apparatus for filling product into containers includes a working chamber through which the containers pass and the containers are acted upon by a sterile fluid to avoid contamination. An external line extends through the working chamber having a plurality of gas openings for the introduction of sterile air into the working chamber and that an internal line extends into the external line having a plurality of openings for spraying a cleaning medium. An annular chamber extends in a longitudinal direction between the internal and the external line. The cross-sectional area of the annular chamber varies in the longitudinal direction so that an even distribution of sterile air emerging from the gas openings into the working chamber is achieved.
