Patent number: 5630327Abstract: The present invention is an immersion freezer which employs a postcooling chamber. The immersion section of the freezer initially immerses all or part of the items to be frozen (typically food items) in a bath of a liquid refrigerant to impart a crust freeze on the items, which locks in moisture and prevents clumping. The postcooling chamber, located underneath the immersion section, then uses the vaporized refrigerant from the immersion section to complete the freezing process while also maximizing efficiency. The postcooling chamber also imparts agitation to the items (which further prevents clumping) through the use of a series of cascading conveyor belts.Type: GrantFiled: March 5, 1996Date of Patent: May 20, 1997Assignee: Air Products and Chemicals, Inc.Inventors: Edward F. Kiczek, Donald J. Ehnot, Richard Reider, Brian Sink

Patent number: 5517827Abstract: The present invention is a tunnel freezer which incorporates a "dual flow" design whereby the refrigerant is introduced at each end of the tunnel and withdrawn from the middle of the tunnel. A key to the present invention is that the dual flow design allows one to confine the pressure gradient for leaks between the ends of the tunnel where it will not be a concern since the item entrance and exit ports (which ports provide a ready access for leaks) are located at the ends of the tunnel.Type: GrantFiled: November 2, 1994Date of Patent: May 21, 1996Assignee: Air Products and Chemicals Inc.Inventors: Edward F. Kiczek, Joseph P. Cohen, David J. Klee, Robert J. Shaw

Patent number: 5509277Abstract: The present invention is a combination immersion/impingement tunnel freezer. A solid conveyor belt moves the items to be frozen through an initial immersion section wherein the conveyor belt is immersed in a bath of liquid refrigerant. Subsequently, the conveyor belt moves the items to be frozen through an impingement section wherein the evaporated refrigerant from the immersion section is directed toward the solid conveyor belt at a high velocity and at an angle substantially perpendicular to the longitudinal axis of the tunnel.Type: GrantFiled: December 14, 1994Date of Patent: April 23, 1996Assignee: Air Products and Chemicals, Inc.Inventors: Edward F. Kiczek, Jeremy P. Miller, Joseph P. Cohen

Patent number: 5509278Abstract: The present invention is a tunnel freezer which employs two distinct chambers for crust freezing the bottom surfaces of items to be processed without substantially refrigerating the remainder of the items. In this manner, the product is made ready for transfer to downstream operations without worry of sticking to belt surfaces. The present invention has application in setting the bottom surface of food items such as cookies, bakery items, caramel coated candies, taffy and the like.Type: GrantFiled: April 20, 1995Date of Patent: April 23, 1996Assignee: Air Products and Chemicals, Inc.Inventors: Edward F.

Patent number: 5059151Abstract: Method and apparatus for opening a mollusk (e.g., oyster) by rapidly cooling said mollusk to a surface temperature of about -100.degree. F. followed by mechanically agitating said mollusk whereby the mollusk shell opens and at least one eye of the mollusk meat is detached from the shell. Subsequent to cooling and prior to agitating, the mollusk can be rapidly immersed in a water bath to raise the surface temperature of the mollusk to no more than about -50.degree. F. Individually quick frozen mollusk meat can be prepared rapidly either as an individual portion of meat or on the half shell.Type: GrantFiled: November 14, 1990Date of Patent: October 22, 1991Assignee: Air Products and Chemicals, Inc.Inventor: Edward F.

Patent number: 4859173Abstract: In its simplest sense, the burner of the present invention includes a swirl chamber for creating a swirling flow path for primary combustion air. The burner also includes means communicating with the swirl chamber for introducing low heating value gas to the primary combustion air for discharge with the air into a flame zone. Also provided are means adjacent to each other for introducing secondary air and for introducing secondary low heating value gas positioned so that the secondary air and secondary low heating value gas intersect the flame zone, preferably above the region of the recirculating core of the flame and at such a point that the secondary air and low heating value gas have a minimal effect on the swirl aerodynamics of the flame.Type: GrantFiled: September 28, 1987Date of Patent: August 22, 1989Assignee: Exxon Research and Engineering CompanyInventors: Lester W.

Patent number: 4614490Abstract: In accordance with the present invention an improved liquid fuel atomizing gun and method is disclosed wherein optimal efficiency atomization is accomplished by introducing liquid fuel under pressure in a first swirling spiral direction into a mixing chamber. The mixing chamber also includes means for introducing steam through a plurality of inclined orifices to introduce the steam and impact the sprayed liquid fuel in a contra-rotational swirl direction. This arrangement of opposite swirling directions of the injected fuel and steam in the gun mixing chamber produces maximum turbulence between the two fluids as each impinge upon the other in relative close proximity so that the kinetic energy of each stream, both oil and steam, is released as the opposing streams meet. The impact of such opposed liquid fuel and steam streams produces higher Reynolds numbers which result in additional turbulence for enhanced mixing.Type: GrantFiled: April 1, 1985Date of Patent: September 30, 1986Assignee: Exxon Research and Engineering Co.Inventors: Edward F. Kiczek, Mervyn J. Beckner, Emiliano Trimon
