Certain exemplary aspects of the present disclosure are directed towards a manufacturing apparatus including a first chamber having a first cavity, and a first actuator. The first actuator aligns the opening of the first chamber to an opening in a second chamber having a second cavity, sealing the first cavity to the second cavity. The manufacturing apparatus further includes gas flow componentry that in conjunction with the first actuator and first chamber evacuate the second cavity by drawing a vacuum in the first cavity. After the second cavity is evacuated, the gas flow componentry fills the second cavity filled with a gas by introducing the gas to the first cavity. A second actuator seals the gas in the second cavity by applying a seal that covers the opening in the second chamber while the first and second cavity remains sealed to one another via the first actuator.

The invention comprises a method and apparatus for infusing a product component, comprising the steps of: placing the product component into a container; positioning into the product component an expansion agent, the expansion agent comprising at least one of a liquid form and a solid form; pressure sealing the container; forming, through a phase change of the expansion agent, gas bubbles of the expansion agent in the product component; and forming a gas phase propellant of the expansion agent in the container, where the product component is permeated with the expansion agent, such as where the product component is a cream, fat, dairy product, and/or milk substitute.

Systems and methods for transporting live insects in a secure and environmentally controlled manner. The systems include containers and packaging for transporting the live insects at a controlled temperature and pressure.

The disclosure provides a smart heat sealing method for vacuum packaging, comprising steps of: recording a time interval t between two adjacent starts of a heating device which is continuously started a number of times; recording a number k of starts of the heating device; obtaining a first heating coefficient p.sub.1 based on t, obtaining a second heating coefficient p.sub.2 based on k, selecting the heating constant t depending on specified parameters and performance of the vacuum package machine, and calculating the heating time T for next operation of the heating device by a formula T=p.sub.1*p.sub.2*t based on p.sub.1, p.sub.2, and t. It solves the heat accumulation problem of the heating device caused by too much repeated use or overuse in short time interval, and thus avoids unsuccessful vacuuming and solves the problem of poor heat sealing effect, and greatly improves user experience.

When the opposing housings (1, 8) of the apparatus are closed, they form between them a small main chamber (P) delimited above by the film (H) for covering the tray and below by the tray (V) itself containing the product (M), and laterally by any suitable mechanical interface structure which surrounds the perimeter of said film and connects it to the perimeter of the upper edge (B) of the tray, this interface structure having holes (22) which are suitably distributed, are located outside the perimeter of the tray, and communicate with said main chamber (P). One or more of these holes (22) open(s) on at least one side of the tray and is/are connected to a first circuit (23, 24), while another one or more of said holes (22) open(s) on at least one opposing side of the tray and is/are connected to a second circuit (17) which in turn is connected to the inner chambers of the two housings (1, 8). Means (18, 19, 20) are provided to operate in such a way that, in the step of vacuum formation, both said first circuit (24) and said second circuit (17) are connected to vacuum forming means (21) which are kept active for a sufficient time to eliminate some of the air from the inside of the tray and to act in such a way that said first circuit (24) is connected in the next step or at the correct time to means (25) for supplying the process gases, while said second circuit (17) is closed or remains in communication with the vacuum means (21) to ensure that the process gas entering the tray from said first circuit (22, 24) causes the residual air in the tray to flow out from and/or towards said second circuit (22, 17), thus flushing and saturating the inner volume of the tray, which is subsequently sealed using known steps and means for welding and finally cutting the film (H).

A sealing and pressure dosing apparatus, and container filling method, including a capping machine (102) which receives containers (1). Closures (80) are applied to the containers (1) immediately following the raising of pressure within the containers (1) by a pressure dosing system in a pressure sealing chamber (84). Preferably a cooling system is integrated with the capping machine.

A pneumatic tube system, including at least one system control module for controlling delivery of a pneumatic carrier through pneumatic tubing. The system includes at least one pneumatic tube station having a sealer, the sealer includes a heating pad and a sealing strip, where the sealer automatically grips the open end within the heating pad and the sealing strip upon insertion of the bag into the system. In one example, the sealer creates a vacuum to extract air from an interior space of the bag. The sealer applies heat to the open end to seal the bag. The system includes at least one pneumatic tube station configured for sending at least one carrier, the at least one sending pneumatic tube station being in signal communication with the at least one system control module, where the at least one carrier is sent through the system by pneumatic tubing.

An assembly for securing a film to an object is provided. The assembly may comprise a lid comprising a surface configured to receive the film, where the surface comprises a plurality of vent openings through which positive pressure or vacuum may be applied to the film. The application of a vacuum may flatten the film against the surface. The assembly may also comprise a base comprising a cavity configured to receive and support a tray, and at least two receptacles configured to receive at least two pegs of the lid. The film may comprise a molecular array which may be immobilized on one side of the film.

A feeding device for gassing a container and a lid in a gassing area during feeding to a sealer includes a container feeder for feeding the container through the gassing area along a first feed path, and a lid feeder arranged on the container feeder such that a lid can be moved through the gassing area along a second feed path to the container and can be placed on the container at one end of the gassing area, and a gassing device arranged stationary at the gassing area for gassing the container and the lid in the gassing area.

The present invention provides a vacuum air extraction device with high practicality and reliability. The vacuum air extraction device with high practicality and reliability includes an air extraction host machine and a vacuum sucker in matching connection to a lower part of the air extraction host machine, where a control circuit board, a vacuum air pump and a decompression valve are arranged in the air extraction host machine; an annular groove body is formed in one end connected to the air extraction host machine, of the vacuum sucker; a spongy body for filtering air is arranged in the annular groove body; air extracted through the air extraction host machine passes through the air circulation channel to enter the annular groove body, is filtered at the spongy body, and then flows into the vacuum air pump.
