General Description
The SCCB series fully automatic liquefaction injectors are engineered for a wide range of liquefaction applications, notably in syrup and starch-sugar production lines. Their design eliminates any components prone to corrosion or clogging, ensuring continuous, uninterrupted operation. Intense turbulence instantly mixes steam and liquid, accelerating and simplifying the liquefaction process and allowing subsequent production steps to proceed smoothly. Despite their compact size, these injectors deliver exceptional efficiency in starch-sugar processing lines.
Key Features
-
Instant, Silent Heat Transfer: The sensible and latent heat of steam is injected directly into the liquid without vibration or the loud “steam hammer” noise.
-
Precise Steam Flow Control: Adjusting the cross-sectional area between the steam valve stem and nozzle allows for fine, step-wise regulation of outlet temperature.
-
Vibration-Free Mixing: The mixing tube operates without generating vibrations and permits both pressure and flow adjustments.
-
Immediate Temperature Response: There are no obstacles or lag in heat transfer; the control system can hold outlet temperature within ±1 °C.
-
Nearly 100% Thermal Efficiency: Both sensible and latent heat of the steam are fully transferred to the liquid, achieving virtually lossless heat exchange.
Operating Principle
The SCCB series injectors rely on contact-type steam injection for liquefaction. High-pressure steam enters the injector body and exits through a nozzle into the mixing tube, where it meets the liquid under intense turbulent flow. This ensures instantaneous heat transfer from steam to liquid with practically no energy loss, rapidly achieving the desired outlet temperature.
-
Outlet Temperature Control: Regulating the steam flow—by narrowing or widening the gap between the valve stem and nozzle—directly adjusts the outlet temperature.
-
Flow Rate Adjustment: Axial movement of the mixing tube modulates liquid line pressure and flow.
-
Uninterrupted Operation: The internal flow passages prevent clogging, and the vibration-damping mounting design extends maintenance intervals and reduces downtime risk.
Product | Jet Cooker Application |
|---|---|
Ethanol (Ethyl Alcohol) | Used for the primary liquefaction of corn, wheat, or rye mash; the slurry is passed through the jet cooker at 221 °F (105 °C) for 5 minutes, then held at 180–190 °F (82–88 °C) for 1–2 hours prior to enzymatic processing. |
Corn Starch | Used in wet milling processes for gelatinization and liquefaction of starch slurry; controlled heating between 160–300 °F (71–149 °C) and high-turbulence mixing to solubilize the starch. |
Wheat Starch | Used for hydrothermal liquefaction of wheat starch; provides homogeneous heating and continuous flow before enzymatic hydrolysis for efficient conversion. |
Citric Acid | Used to continuously sterilize and heat fermentation media; direct steam injection via the jet cooker enables short-duration (flash) high-temperature sterilization. |
Xanthan Gum | Used to heat fermentation media before inoculation and to heat polymer solutions post-fermentation; high-shear, turbulent mixing ensures homogeneous viscosity control and particle dispersion. |
Lysine | Used to heat and sterilize amino acid fermentation media; rapid heating via the jet cooker reduces infection risk and the medium is fed directly into the fermenter. |
Sorbitol | Used to liquefy and gelatinize starch-based glucose syrups prior to hydrogenation; pre-heats the syrup with the jet cooker to produce a low-viscosity feedstock ready for enzymatic hydrolysis. |
Maltodextrin | Used for primary liquefaction of starch syrups in maltodextrin production; controlled heating and continuous mixing yield a homogeneous syrup with low dextrose equivalent (DE). |
Modified Starch | Used as a pre-treatment for starch granule disruption and to increase reactive group accessibility; the jet cooker provides controlled thermal and mechanical action. |
Maltose/Dextrose Syrup | Used for liquefying starch solutions prior to saccharification; the jet-cooked syrup is prepared for enzyme reactions. |
Lactic Acid | Used to heat and sterilize lactic acid fermentation media; the jet cooker supplies a sterilized, heated medium directly to the fermenter. |
