摘要： A scraped surface heat exchanger is disclosed which includes a heat exchange cylinder and a vertically disposed rotating drum positioned within the cylinder having pivotal scraping elements on the periphery thereof for scraping the cylinder interior surface. The cylinder and drum define an annular product flow chamber through which product is pumped in heat transfer relationship to the cylinder. The heat transfer cylinder is surrounded by a thermally insulated jacket which in combination with the cylinder defines an annular flow chamber for circulation of a heat transfer medium to facilitate cooling or heating of product passing through the product flow chamber. The drum is mounted on a shaft which is journaled in a bearing at only one end, requiring utilization of only a single seal to seal the bearing from the product being heated or cooled. An indicator element integral with a carrier to which a rotating seal element is attached moves as the seal wears to provide a visual indication of seal wear. The carrier is designed such that the net product force acting on the carrier is in a direction tending to urge the relatively moving seal element together. Rotary agitating elements are provided at the inlet to the annular product flow chamber to distribute product, which is introduced at a single point, to the entirety of the inlet end of the annular product flow chamber. A mixing chamber located between the outlet end of the annular product flow chamber and the outlet of the heat exchanger is provided with cooperating stationary and rotary agitator elements to mix the product, thereby assuring uniform temperature distribution of product leaving the heat exchanger. A temperature sensor is mounted to the inner end of one of the stationary agitator elements to monitor the temperature of the material leaving the heat exchanger.
摘要翻译： 公开了一种刮面式热交换器，其包括热交换圆筒和位于圆筒内的垂直设置的旋转滚筒，其具有用于刮削圆筒内表面的圆周上的枢转刮削元件。 气缸和滚筒限定了一个环形产品流动室，通过该环形产品流动室将产品与气缸的热传递关系泵送。 传热滚筒被一个绝热的外壳包围，该外壳与圆筒组合形成一个环形流动室，用于循环传热介质以便于冷却或加热通过产品流动室的产品。 滚筒安装在仅在一端轴承在轴承中的轴上，仅需要使用单个密封件将轴承与被加热或冷却的产品密封。 与承载件成一体的指示元件，旋转的密封元件附接到该指示元件，随着密封件的磨损而移动，以提供密封件磨损的视觉指示。 载体被设计成使得作用在载体上的净产品力处于倾向于将相对移动的密封元件推到一起的方向。 旋转搅拌元件设置在环形产品流动室的入口处，以将在单个点引入的产品分配到环形产品流动室的入口端的整体。 设置在环形产品流动室的出口端和热交换器的出口之间的混合室设置有协作的固定和旋转搅拌器元件以混合产品，从而确保离开热交换器的产品的均匀的温度分布。 一个温度传感器安装在一个固定搅拌器元件的内端，以监测离开热交换器的材料的温度。

摘要： A dual cooling tunnel arrangement for cooling viscous heated fluid foodstuffs in flexible bags. The flexible bags containing the heated fluids are received on pivoted wire carriers which are driven by an endless chain through an upper cooling tunnel in a first direction and returned through a second cooling tunnel in the opposite direction. In each cooling tunnel, a cooling water spray is directed on the bags in the carriers as the carriers are slowly rocked, causing the fluid in each bag to flow to different areas of the bag, altering its shape, to produce enhanced heat transfer rates and a more uniform temperature distribution throughout the fluid during cooling.

摘要： A fitmentless, aseptic, temporarily sealed pouch is formed from two multiple-ply side walls sealed together at marginal edges. A portion of the seal is removable. Half seals joining the plies within each side wall are disposed in the side walls proximate the removable seal, but do not seal the side walls together. Apparatus and processes for handling, filling and sealing the pouch in an aseptic chamber include apparatus for moving the pouch through a sterilant bath, into and out of an aseptic chamber, a cutter for cutting off the removable seal, and vacuum jaws for engaging, stretching and opening the pouch. Once opened, the pouch is filled, then closed, sealed and moved out of the chamber through the bath.

摘要： There is disclosed an aseptic flexible walled container having a rigid fitment member cooperative with an aseptic filling apparatus and including a neck, outer flanges surrounding the neck, a frangible membrane and an outer end rim receptive of an hermetically sealed lid. The neck is formed with an internal chamferred seating shoulder for fluid-tight engagement with a fill tube. One outer flange cooperates with clamping jaws of the aseptic filling apparatus for detachably sealing the fitment to a sterilizing chamber and placing it in position for insertion of the filling tube which ruptures the membrane and permits the aseptic introduction of product to the container's interior. The other outer flange is secured to an opening in a wall of the flexible container. The joined fitment and container are presterilized prior to filling. Selected materials for the multi-ply container walls and the fitment permit the container to withstand gamma ray and other sterilization treatment, heat and pressure while maintaining required strength. After the container is aseptically filled, such as with flowable food product, the fill tube is withdrawn and a lid is hermetically sealed onto the rim of the fitment. A heat shield adjacent a container wall surrounds the fitment to protect the container from excessive heat generated by the associated filling apparatus during filling.

摘要： There is disclosed apparatus for aseptically filling a flexible container having a rigid fitment including a neck, outer flange surrounding the neck, a frangible membrane and an outer rim. The apparatus includes an enclosed filling chamber including a platen with an opening, clamping jaws for holding the fitment in the opening, a vacuum head and sealing unit for removing a lid loosely placed on the fitment and supporting it within the sealing chamber while the sealing chamber, fitment and lid are sterilized, a fill tube which is retractable within a housing and shiftable to a position in sealed engagement with the neck to introduce product into the container. After the container is filled, the fill tube is withdrawn and enclosed in its housing, the lid is transferred back onto the rim and heat sealed in place. The fitment is then unclamped to end the filling cycle.
