  • Patent number: 7270842
    Abstract: The invention uses rapid heating to effect a material property change in a biomaterial. The biomaterial is heated to a predetermined real temperature, whereas the biomaterial's total thermal treatment is described by an equivalent temperature and an equivalent time defining a point above a minimum gel set temperature line, above a reduction in bacteria line, below a water loss line, and below a maximum gel set temperature line. According to one aspect of the invention, the biomaterial is heated by exposing the biomaterial to a relatively uniform electric field. The material is heated to a predetermined temperature for a predetermined time in order to achieve a food product characterized by a preselected refrigerated shelf life of from about two weeks to about forty-two weeks. The food product may be packaged prior to the microwave exposure so as to sterilize the packaging and decrease product loss.

  • Patent number: 7213967
    Abstract: A method of generating a temperature measurement for a batch or a continuous stream of material. The method includes providing a particle having a signal that changes at a pre-determined temperature; inserting the particle into the batch or continuous stream; and detecting a signal change from the particle to thereby generate a temperature measurement for the batch or continuous stream. A suitable system for use in carrying out the method is also described.

  • Patent number: 7112954
    Abstract: Methods, Systems, and Devices for Evaluation of Thermal Treatment. A magnetically detectable particle and related methods, systems, and devices are provided for generating a temperature measurement for a batch or a continuous stream of material. The particle can include a first and second magnet each comprising a positive and negative pole. The particle can also include an adhesive having a release temperature and operable to attach one or both of the positive and negative poles of the first magnet proximate to the same polarity pole of the second magnet or to attach one of the positive and negative poles of the first magnet between the poles of the second magnet below the release temperature such that a first magnetic field is generated by the first and second magnet. The adhesive can also be operable to release the first and second magnets from one another above the release temperature.

  • Patent number: 6766699
    Abstract: A method of generating a residence time measurement of a particulate-containing food product while passing the product as a continuous stream through a thermal processing apparatus is described. The method includes the steps of inserting at least one detectable particle, and preferably many detectable particles, tagged with at least one magnetic implant into the stream at pre-selected intervals; detecting the at least one implant using at least one sensor located at a detection point downstream from a location of the inserting of the at least one detectable particle; determining a time of passage of the at least one detectable particle in the stream using output from the at least one sensor; and generating a residence time measurement for the stream using the time of passage for the at least one detectable particle. The method also includes the use of multiple sensors for detecting the implants. A suitable system and detectable particle for carrying the method are also described.

  • Publication number: 20040081730
    Abstract: A microwave exposure chamber is used to process an agricultural commodity. A microwave waveguide connects a microwave source to an exposure region. Sensors measure temperature characteristics of the agricultural commodity as it passes through and exits the exposure region. Heat delivery is controlled by increasing or decreasing the power level of the microwave source and by increasing or decreasing the speed at which the agricultural commodity passes through the exposure region. The microwave exposure chamber removes moisture at a higher rate from high moisture portions of the commodity so as to equalize the moisture content and improve the processing and storage characteristics of the commodity. Also, a method of separating the skin of an agricultural commodity from the agricultural commodity is done by varying temperature through the use of microwave power and the length of electromagnetic exposure time.
