Publication number: 20240011711Abstract: A direct contact steam injection heater that allows shear to be adjusted by modifying a lateral position of a movable combining tube. The movable combining tube includes a rack on an outer surface of the combining tube that engages a movable lever arm of an adjustment mechanism. The pivoting movement of the lever arm moves the combining tube in a lateral direction to adjust the shear in the product being heated. The combining tube is supported in a housing by a pair of lateral bushing and a pair of end seals prevent product from entering the combining tube housing. The lever arm is coupled to a worm gear shaft such that rotation of the worm gear shaft creates pivoting movement of the lever arm and lateral movement of the combining tube.Type: ApplicationFiled: July 5, 2022Publication date: January 11, 2024Applicant: Hydro-Thermal CorporationInventors: James C.

Patent number: 11707151Abstract: A cooking system for cooking a product flow utilizing steam. A supply of steam is provided at a supply pressure that is regulated by a control unit to a regulated pressure. The supply of steam is provided to a plurality of steam injection cookers which are positioned within a product supply pipeline that receives a product flow. The product flow is cooked as the product flow passes through the product supply pipeline and the plurality of cookers. Each of the steam injection cookers includes a steam modulator that controls the amount of steam injected. By regulating the steam pressure and the steam modulator, the control unit can modify the amount of shear created within the product flow and control the temperature of the fluid. The cooking system further includes a clean-in-place system that can inject a cleaning solution into the steam supply pipeline and the plurality of steam injection cookers.Type: GrantFiled: August 28, 2020Date of Patent: July 25, 2023Assignee: Hydro-Thermal CorporationInventors: James C.

Patent number: 11525571Abstract: A direct contact steam injection heater that includes a stem plug that is rotatable over 360°. The stem plug is connected to an actuator that is operable to rotate the stem plug over 360° of rotation during both the heating function of the steam injection heater and during a clean-in-place process. The stem plug includes a regulating head having a pair of sealing inserts formed on each of a pair of sealing faces. The sealing inserts are biased outward into contact with an inner surface that includes the steam injection nozzles. As the regulating head rotates between a closed position and an open position, the nozzles are exposed to allow steam to flow into the product being heated. The regulating head further includes a pair of foils. During the clean-in-place operation, the foils create a turbulent flow of cleaning liquid within the steam chamber.Type: GrantFiled: May 1, 2020Date of Patent: December 13, 2022Assignee: Hydro-Thermal CorporationInventors: James C.

Patent number: 10982178Abstract: A system and method for generating wort utilizing steam injection heating and stratified flow. The system mixes a fine ground grain with water to form a slurry. The slurry is pumped through a steam injection heater to form a mash. The heated mash enters into a stratified vessel that creates a stratified temperature profile from a first end to a second end. The stratified heating vessel allows the mash to flow from the first end to the second end without internal mixing. After retention within the mash coil, the wort is directed to a mash filtration unit. After filtration, the wort enters into a boil kettle and is heated using a second steam injection heater. The boil kettle includes a spray head that directs brewing liquor onto the wort to reduce foam within the boil kettle. Finally, the wort passes through a scraped surface sieve that removes particles from the heated wort.Type: GrantFiled: October 3, 2017Date of Patent: April 20, 2021Assignee: Hydro-Thermal CorporationInventors: Sean O'Rear, James C.

Patent number: 10220371Abstract: A method and system of depressurizing a molecular sieve used in ethanol production is shown and described. The method and system utilizes a vapor mixing condenser that receives a vapor sieve feed from the molecular sieve during the depressurization cycle. The vapor from the molecular sieve during the pressurization cycle is used to heat the 190-proof product flow. The heated product flow is diverted directly to the 190-proof product vaporizer, which increases the input product flow temperature to the vaporizer, thereby reducing the amount of heat needed to vaporize the 190-proof product flow. The reduction in heat needed reduces energy costs and increases equipment life.Type: GrantFiled: October 10, 2016Date of Patent: March 5, 2019Assignee: Hydro-Thermal CorporationInventors: James Zaiser, Scott Lucas

Patent number: 7025338Abstract: A direct contact steam injection heater is placed directly in line with a flow of stock through a pipe. The steam injection heater includes a Mach diffuser having a plurality of steam diffusion holes and an adjustable steam-plug cover that is positioned within a stationary diffuser tube to modulate the amount of steam added to the flowing stock by exposing a desired number of steam diffusion holes. The steam tube assembly includes an O-ring that forms a seal along the inner wall of the diffuser tube to prevent the flow of stock into the steam tube assembly when steam pressure is not present. Select areas of the steam injection heater, including the deflection plate, diffuser tube and heater body inner wall are coated with a wear coating such as tungsten carbide. Further, a pair of pressure ports are formed in the steam-plug cover to equalize the pressure between the open interior of the steam-plug cover to further facilitate rotation of the steam-plug cover.Type: GrantFiled: February 9, 2004Date of Patent: April 11, 2006Assignee: Hydro-Thermal CorporationInventors: Bruce A.
