Abstract:
The present invention allows a beverage manufacturer to package variety packs of beverages while it is filling various beverages. The improved system that carries out the method includes an onsite accumulator that eliminates the long-standing practice of packaging variety packs at a separate location from where the beverages are packed.
Abstract:
A container-processing apparatus includes a pasteurizer with plural zones, and a transport element. The zones, which follow one another in a transport direction, include a preheating set, a cooling set, and pasteurizing set. The transport element moves containers through the sets, where they are subjected to a treatment medium at different treatment temperatures. Treatment temperatures in zones in the preheating set rise in steps from zone to zone. In the pasteurizing set, treatment temperature is maintained at or above pasteurizing temperature. In the cooling set, treatment temperatures decrease in steps zone to zone. The transport element transports containers in the pasteurizer at a changeable transport speed that is subject to continuous control.
Abstract:
A microwave heating system configured to heat a plurality of articles is provided. The microwave heating system includes a microwave splitter, a pair of microwave launchers, and at least one inductive iris disposed between the splitter and the launch opening of one of the launchers. A microwave launcher suitable for use in such a heating system is also provided. The launcher includes an inductive iris disposed within the interior of the launcher, spaced between its inlet and outlet and obstructing at least a portion of the microwave pathway.
Abstract:
A microwave heating system configured to heat a plurality of articles and a process for using the same are provided. The microwave heating system includes a liquid-filled thermalization zone, a liquid-filled microwave heating zone, and a pressure lock system disposed therebetween. The pressure lock system includes a pair of locking gate valves and a pressure adjustment chamber configured to transition the articles being heated from the thermalization zone to the microwave heating zone, which may be operated at different pressures.
Abstract:
A retort container includes a metal end applied and sealed to an all-thermoplastic container body by a crimp-seaming or double-seaming operation. The metal end has an outer curl joined to a chuck wall that extends down from the curl. One or both of the inner surface of the container side wall and the outer surface of the chuck wall has/have a heat-sealable material thereon. The metal end is crimp-seamed or double-seamed to the container body and the heat-sealable material(s) are heated to soften or melt such that the interface between the chuck wall and the side wall is fused. The interface is oriented along a direction relative to internal pressure exerted on the metal end such that stress on the interface caused by the internal pressure is predominantly shear stress.
Abstract:
Systems and methods for packaging food products, such as fruits, vegetables, and meats. Specifically, the described methods relate to systems and methods for packaging food products in a manner that increases the products' shelf life. Generally, the methods begin by providing a food product. In some cases, debris is removed from the food product. To kill bacteria and other microbes on the food product, the food product is optionally washed in ozonated water. To deactivate enzymes within the food product, the food product is heated, though not necessarily cooked or blanched. The food product is then typically sealed in a barrier package containing between about 1 percent and about 50 percent oxygen, by volume. In some cases, the sealed package is then heated to between about 165 and about 285 degrees Fahrenheit to kill microbes in the sealed package. Other implementations are also described.
Abstract:
The present disclosure provides methods and systems for coordinating and balancing continuous product production, including continuous flow processes such as aseptic sterilization with package filling rate. The methods and systems include an averaging level control scheme to actively manage the balance between the continuous flow rate and the package filling rate. The methods and systems allow the flow rate to be adjusted for changes in the package filling rate, preventing a need for stoppage of the continuous product production.
Abstract:
A method for heating a plurality of articles according to a prescribed heating profile is provided. The method includes heating a first test article in a small-scale microwave heating system and, based on the value of one or more parameters determined during this small-scale heating, determining a prescribed heating profile for the test article. Suitable parameters can include for example, net power discharged, sequential microwave distribution, average temperature and flow rate of the fluid in the heating chamber, and residence time. The heating profile can then be used to control a commercial-scale microwave heating system used to heat a plurality of similar articles.
Abstract:
A method, apparatus and thermal processing medium for accelerated thermal processing, particularly the pasteurization and sterilization of foodstuffs, within a conventional, food processing system comprising at least one processing chamber or tower wherein the system requires no significant structural modification nor additional pressurization of product or apparatus nor requiring any change of physical state of the thermal processing medium, is disclosed. Further aspects of this invention include the elimination of steam to achieve the required level of thermal processing, the optimizing and controlling of the process through the utilization of the space previously occupied by steam by means of extending thermal processing capacity and improving finished product organoleptic properties as well as increased system flexibility and throughput capacity. Finally it relates to effectively eliminating any corrosive properties of the thermal medium which itself is optimized for any specific thermal processing step.
Abstract:
The present invention refers to a new process for preservation of different foods which secures to the processed food an extended shelf life, which can be extended in up to five years without the addition of preservatives, and the use of freezing or cooling. The referred to process further allows keeping the natural characteristics of the processed food, such as flavor and texture. The process for preserving different foods of the present invention comprises the steps: a. Packing food in a package; b. Heating the food/package system keeping the food in contact with the atmospheric air external to the package; c. Changing the gaseous composition inside the package containing food; d. Closing/sealing the package containing food; e. Thermal treatment of the closed/sealed package containing food; and can be used for several types of foods comprising, among them, fish, seafood, poultry, meat, pork, cold cuts, pastes, pasta, cereals, vegetables, fruits, dairy products, ready food, desserts or mixtures thereof.
