Starch is a diverse industry that encompasses multiple products including sweeteners, paper products, foods such as soups, mayonnaise, and beverages. Each of these producers have their own unique concerns. Starch process drawing

Achieving the maximum conversion of starch to sugars is the key goal in both the ethanol and sweetener industries. Once the sugars are created, the goals in these industries change but the process in both to create those sugars is very similar. The need to be able to produce and maintain a very accurate uniform temperature in the mash flow and being able to create an adjustable shear are the two key features provided by the Hydroheater/Jetcooker. Being able to adjust the ΔP is achieved by Hydro-Thermal’s adjustable combing tube. This feature provides the ability to create the optimal amount of shear to optimize yield, produce a very high level of product quality in the case of sweetener plants, reduce enzyme use, and reduce overall energy use. Hydro-Thermal’s patented heating solution addresses these issues and comes with a team of experts ready to help you achieve your processing goals.

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 the paper production area.

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

Here is what makes each solution unique:

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.

 

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.
