Achieving the ideal yield, producing desirable co-products, and reducing energy usage are a few of the many challenges facing ethanol producers. ethanol drawing process

If you need to ensure a maximum yield during the mashing process or want to reduce energy usage per bushel, we have your solution. Replace your heat exchangers and spargers with a product that will improve your product quality, ensure consistency and production efficiency.  

Hydro-Thermal’s patented heating system works by mixing steam and process liquids completely while delivering consistent temperature and instantaneous heating. For more information on our advanced direct steam injection technology, click here.

 


Heating products utilizing direct steam injection

The type of heater you need is dependent on how it will be used. No matter what your application, Hydro-Thermal has the solution for every application in ethanol and biofuel production.

All of our heaters share unique benefits, including internal modulation, self cleaning ability and rugged design and construction.

Here is what makes each solution unique:

Industrial Hydroheater (Also known as the Jetcooker™)

  • Volume capability: flow rates up to 6,700 gpm [1,522 m³/hr]
  • Precise temperature control ±1°F [.50°C]
  • Available in a variety of alloy materials including: Stainless Steel (316, 316L, 317L, AL6XN, 254SMO & 2205), Hastelloy & Titanium.
  • Adjustable pressure drop to control the shear (high or low)
  • High steam capacity
  • High solids capability
  • Hydroheater has a liquid turndown of 2:1 for starch conversion, and up to 3:1 for water-like fluids. If a greater turn-down is required consult Hydro-Thermal Engineering.
  • Available in sizes from 1/8” to 12”
  • Rating: 1/8” to 2-1/2” NPT (300 psig at 450 F), 2” to 12” flanged (150# 195 psig at 400 F, 300# 300 psig at 450 F, PN16 16 barg at 221 C, PN40 20.7 barg at 232 C)
  • Right angle design
  • All Industrial Hydroheaters include a combining tube. An extended combining tube may be recommended for a large ΔT (high temperature rise). Please contact Hydro-Thermal for more details.

  • Handles heavy slurries, medium consistency pulp stock or higher solids content.
  • Up to 10:1 liquid turndown
  • Connections: ANSI Class 150; ANSI Class 300; DIN PN16, PN25, PN40, Others upon request
  • Viscosities up to 40,000 cP, consult factory for higher values
  • Ensures thorough mixing and uniform temperature profile
  • Low shear, maintains chunk size
  • High flow rates
  • Easily plumbs into existing plant utilities.

Optional Enhancements

Autopilot: The Autopilot automatically adjusts the Hydroheater’s product flow path as process conditions change to maintain a constant pressure drop across the unit. This results in optimized shear, mixing characteristics, and more effective starch conversion, leading to lower enzyme usage and higher yields.

 

Co-Pilot™: The Co-Pilot™ is designed to complement the K600 Hydroheater and K6 Autopilot, and is used to calibrate the electrical “zero” position of the Combining Tube (CT). Once the Autopilot PLC program is updated for the K600 Hydroheater, the Co-Pilot can be used to calibrate the CT while the heater is offline for maintenance. No further programming is required from Hydro-Thermal of the PLC.

 

Actuator Options Available

Hydro-Thermal's heaters utilize a Fisher reverse-acting diaphragm actuator (“fail close”). Generally coupled with a filter/regulator and a Fisher DVC 2000 or a DVC 6200 positioner that converts a 4-20 mA DC input signal to pneumatic output signal to the actuator. For high vibration applications remote mount positioners are available. Alternative positioners are available depending on unique processing conditions or upon request. Please contact Hydro-Thermal for more details.

 

Non-Obstructing Heater (NOH)

  • Volume capacity: 30 up to 6,900 gpm (6.8 up to 1,567.2 m3/hr)
  • Body and stem plugs in 316SS, and diffuser in 316L or 17-4PH (other materials available pending on request or per application)
  • Straight tube design allows unrestricted flow
  • Low pressure drop
  • Trim heating control for high turndown
  • Able to handle abrasive (sand or grit) and large particulate/fibrous materials
  • Available in sizes from 2” to 12”
  • Heater rating of 300 PSIG @ 450°F
  • Raised face flanges designed per ANSI B16.5 with lugged connections
  • For more information on the NOH, please click here.

 

Fluid Heating Systems

EZ Skid™: Complete skid systems utilizing the EZ Heater®. The EZ Skid is available in 5 standard sizes and is only used for hot water applications. For more information, click here.

 

 

ATTEC®: ATTEC or Advanced Fluid Heating Skids are completely customized solutions that are designed, built and installed to individual specs. Hydro-Thermal will provide necessary components including piping and control systems. These skids can be used for processing any type of slurry including starch cooking, food manufacturing, chemical processing and everything in between. For more information, click here.
