A cart treatment system according to the present invention includes: a pre-treatment module for cart treatment; an intermediate module provided to receive and treat the cart which is treated in the pre-treatment module; and a post-treatment module provided to receive and treat the cart which is treated in the intermediate module, wherein the intermediate module is provided to be put in either a coupled state in which the pre-treatment module is coupled to the post-treatment module or a detached state in which the pre-treatment module is detached from the post-treatment module.

A 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.

The invention relates to a method and a device for treating foods and/or containers for holding foods. The foods and/or containers (2) are treated in at least one treatment zone (4) by a process liquid (3), wherein the process liquid (3) is at least partially recirculated into the treatment zone (4) or the treatment zones (4) after completed treatment of the foods and/or the containers (2). It is provided herein that during continuous treatment at least some or all of the process liquid (3) is used per time unit to form at least one stream (20) of the process liquid (3), the formed stream (20) is filtered by at least one membrane filtration system (19), and a filtered stream (46) is at least partially fed back into an element (8) holding and/or conducting the process liquid (3) and/or into a treatment zone (4).

A microwave heating system configured for heating a plurality of articles is provided. One or more of the microwave launchers can be offset slightly, such that the microwave energy introduced into the heating chamber is discharged at a launch tilt angle of at least 2. Additionally, each launcher can include a microwave-transparent window disposed between the microwave chamber and the one or more launch openings and at least 50 percent of the chamber-side surface of the window can be oriented at an angle of at least 2 from the horizontal.

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.

A retort agitation system (100) for thermal processing of products includes product carriers 102a and 102b mounted on a low friction support system 104 for reciprocal movement of the carriers along the interior of a retort. The product carriers are driven in reciprocating motion by a drive actuator system 106 that can be positioned between the carriers 102a and 102b or endwise of the two carriers 102a and 102b. A drive actuator system 106 is linked to the carriers to cause the carriers to move along non-sinusoidal paths lengthwise of the retort. Reaction actuators 108 act on the carriers in opposition or in supplement to the drive actuator system 106 to apply forces on the carriers for accelerating the carriers along their non-sinusoidal paths of travel.

A microwave heating system configured to heat a plurality of articles is provided. The microwave heating system can include one or more microwave launchers that define at least one launch opening having a depth of not more than about 0.625, wherein is the predominant wavelength of the microwave energy passing through the launcher. Additionally, in some embodiments, the launch opening may have a width or depth that is less than the corresponding inlet dimension, such that the microwave launcher has a generally tapered profile. When the microwave launcher includes a single inlet and two or more launch openings, the center points of adjacent outlets may be laterally spaced from one another relative to the direction in which the articles are passed through the heating chamber.

A gluten-free pasta product that survives retort may be formed by preparing a dough mixture with gluten-free flour and water. The dough can be extruded at a temperature and with an amount of mechanical energy effective to form an extruded pasta product having a bi-continuous matrix of protein and starch. The extruded pasta product can be incorporated into a closed retort container and subsequently retorted. The resulting retorted food product may contain gluten-free pasta that has the structural integrity and textual firmness consistent with that exhibited by traditional wheat pasta after having undergone retort despite the absence of binding gluten molecules.
