An ultrahigh temperature heating system is provided for use in obtaining controlled heating of a liquid product. The system includes an upright chamber into which a controlled amount of liquid product flows and then descends through the chamber in a curtain-like pattern. The descending product passes a steam inlet provided in the chamber wall and is intermixed with and heated by a controlled amount of entering steam whereby the temperature of the descending product is increased to a predetermined amount. A pump is connected to an outlet formed in the lower portion of the chamber and removes therefrom the mixture of product, condensate, noncondensable gas, and steam so as to prevent an accumulation therein of said mixture while at the same time maintaining a predetermined pressure within the chamber. The discharge side of the pump is connected to an intermixing means causing all of the steam entrained in the product to condense. Upon leaving the intermixing means the mixture of the product, condensed steam and noncondensable gas enters a holding tube and is retained therein for a predetermined interval of time at a predetermined temperature.

An ultrahigh temperature heating system for a liquid product of known specific gravity and specific heat, said system comprising a source of product at a predetermined first temperature; an upright chamber including a product inlet disposed adjacent the upper end portion thereof and communicating with said source for receiving at a predetermined first flow rate the product at the first temperature, an outlet disposed adjacent the lower end portion of said chamber, and a steam inlet disposed intermediate said inlet and outlet through which a controlled amount of steam at a first pressure and at a predetermined second temperature is adapted to flow into said chamber and intermix with the product descending within said chamber and heat same to the predetermined second temperature; first means connected to said chamber outlet for removing from said chamber the mixture of product and steam at a predetermined second flow rate whereby there is no accumulation of same in the chamber lower end portion; second means for exerting a predetermined second pressure on the product and steam removed from said chamber whereby all of the steam is condensed and mixed with the product; and third means connected to said second means for retaining the mixture of the product and steam condensate for a predetermined time interval and at the second temperature and pressure.
