A method for enabling a first terminal to access a wireless network, includes: receiving an access request sent from the first terminal, the access request including a terminal identification of the first terminal; determining whether the first terminal meets a condition based on the terminal identification included in the access request; sending a connection invitation to the first terminal if it is determined that the first terminal meets the condition; receiving a connection request sent from the first terminal based on the connection invitation; and enabling the first terminal to access the wireless network based on the connection request.

A system includes a vacuum chamber, a vacuum source, and a mixture flow path adapted to be connected to receive the output of a direct steam injector. The vacuum source is operatively connected to a vacuum port of the vacuum chamber, while a product outlet port from the vacuum chamber is adapted to be connected to an arrangement for removing treated product from the vacuum chamber. The mixture flow path includes a flow path segment outside of the vacuum chamber volume and a flow path segment within the vacuum chamber volume. At least some of a surface defining the flow path segment within the vacuum chamber is in substantial thermal communication with one or more cooling structures.

A cooling system is provided. The cooling system comprises a first solution tank configured for receiving a cooling fluid. The cooling system may also include a second solution tank within the first solution tank and configured for receiving a food edible solution. The cooling system may also include a cooling fluid tube coiled around the second solution tank. The cooling system may further include a food edible solution tube coiled around the cooling fluid tube and/or the second solution tank.

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 method for freezing a food product in a cryogenic freezer includes sensing at least one physical characteristic of the food product in real time, providing a cryogenic substance to the food product for heat transfer at said food product, automatically self-adjusting the heat transfer at the food product responsive to the sensing the at least one physical characteristic, and continuously self-adjusting the heat transfer for bringing the food product to a select temperature. A related freezer apparatus is also provided.

A method for decontaminating articles having porous outer surfaces. The method includes steps of: providing a decontamination chamber; conveying the articles through the decontamination chamber at a predetermined speed wherein the speed is selected such that the articles are disposed in the decontamination chamber for a predetermined period of time; providing a source of sterilant vapor, the source providing the sterilant vapor at a temperature within a predetermined acceptable temperature range and at a concentration within a predetermined acceptable concentration range; conveying a sterilant vapor from the source of sterilant vapor to the decontamination chamber; and exposing the articles to the sterilant vapor. The predetermined period of time and the predetermined acceptable concentration range of the sterilant vapor are selected such that the sterilant vapor does not penetrate the porous outer surfaces of the articles.

Methods and apparatuses for thermally treating flowable materials using electromagnetic radiation, and foods and materials obtained thereby. Also provided are methods of continuous flow thermal treatment of biomaterials, apparatuses for performing the same, and products prepared using the methods and/or apparatuses.

In at least one illustrative embodiment, an electromagnetic filter may include a transfer pipe and multiple electromagnetic filter elements positioned in an interior volume of the pipe. Each electromagnetic filter element includes a support comb, a solenoid coupled to the support comb, and multiple magnetic members arranged in a planar array positioned within an opening of the support comb. Each magnetic member may rotate about an end that is coupled to the support comb. The magnetic members may be magnetostrictive sensors and may include a biorecognition element to bind with a target microorganism. A method for fluid filtration includes coupling the electromagnetic filter between a fluid source and a fluid destination, energizing the solenoids of each electromagnetic filter elements, and flowing a fluid media through the transfer pipe of the electromagnetic filter. The fluid media may be liquid food such as fruit juice. Other embodiments are described and claimed.

A height adjustable support comprising a threaded support channel a cylindrical support post, positioned within the support channel and at least one saddle brace positioned within the support channel and to partially surround the cylindrical support post. In the present invention, the downward force resulting from the weight of the equipment results in static friction between the saddle brace and the cylindrical support post that is sufficient to hold the equipment surface at a desired height. The height adjustable support may be implemented into hygienically designed food processing equipment to eliminate undesirable bacteria harboring surfaces and to improve height adjustability of the equipment.

The present example embodiments relate to food preparation devices using natural flowing and/or fan driven circulating air, and details for the construction thereof. Example embodiments are shown, which may be reduced in size and volume by the user. Example embodiments are shown which utilize natural convection airflow. Example embodiments are also shown which utilize fan driven air which flows in alternating directions.
