  • Electrically stable methods and apparatus for continuously electroheating food
    Patent number: 5771336
    Abstract: Electrically stable electroheating apparatus and methods for continuously treating pumpable food are provided. The electrodes of the electroheater are connected to a source of AC electric current which resistively heats the food by passing current through it. The electrodes of the electroheating cell are also connected in parallel with at least one resistor. The stabilized electroheater provides long run times and prevents arcing within the food.
    Type: Grant

  • Methods and apparatus for electroheating food employing concentric electrodes
    Patent number: 5758015
    Abstract: An electroheating apparatus to continuously treating pumpable food is made up of a number of connected electroheating cells. In one embodiment, all of the cells include a pair of concentric electrodes between which the food is pumped. The electrodes are connected to a high frequency energy source which passes current through the food to heat them based upon their own resistivity and the electrode gap. In another embodiment, two different functioning electrodes are used, connected in series, so as to provide long run times and high process temperatures.

  • Shelf-stable liquid egg
    Patent number: 5741539
    Abstract: Methods of and apparatus for producing shelf-stable liquid egg are provided. In particular, methods of and apparatus for producing liquid egg having a shelf life of at least 5 days when stored at about 70.degree. F. (about 21.degree. C.) are provided. In a first preferred embodiment, the liquid egg is electroheated from a temperature of about 110.degree. F. (about 43.degree. C.) to a temperature of at least about 140.degree. F. (about 60.degree. C.) by applying high frequency alternating electric current. The liquid egg is then cooled and again electroheated. In a second preferred embodiment, the liquid egg is electroheated from a temperature of about 110.degree. F. (about 43.degree. C.) to a temperature of at least about 140.degree. F. (about 60.degree. C.) by applying high frequency alternating electric current. The liquid egg is then cooled. A plurality of high voltage electric pulses are then applied to the liquid egg.
