Antimicrobial ultraviolet device
View Patent ↗Disclosed herein is an apparatus for treating food products, such as any species of meat (beef, pork or lamb) and ground beef, being transported in a fluid, such as carbonic acid liquid carbon dioxide, at a pressure sufficient to maintain the carbon dioxide as a liquid.
1. A method for treating food, comprising:
providing solid food in a fluid to create a fluidized suspension comprising solid food;
transferring the fluidized suspension through a conduit, wherein the conduit is transparent to a wavelength of energy, wherein the energy is harmful to bacteria, wherein the solid food is carried in the fluidized suspension within the conduit;
directing energy from an exterior location into the conduit, wherein the energy is harmful to bacteria and the energy passes through at least a wall of the conduit and fluid to strike the food; and
producing turbulence within the conduit and causing rotation and tumbling of the food within the fluidized suspension as the fluidized suspension passes within the conduit and is irradiated with the energy passing through the conduit wall.
2. The method of claim 1 , wherein the fluid is liquid carbon dioxide.
3. The method of claim 1 , wherein some of the energy is reflected before passing through the conduit.
4. The method of claim 1 , wherein the food is meat or ground beef.
5. The method of claim 1 , further comprising arranging energy emitting elements in a circular pattern lengthwise with respect to the conduit so as to encircle the circumference of the conduit.
6. The method of claim 1 , further comprising arranging pairs of energy emitting elements with reflectors in a circular pattern lengthwise with respect to the conduit to encircle the circumference of the conduit.
