TSP Production: ExPress® Soy vs. Hi-Pro (Solvent) Meal
A common question that arises when a company analyzes making texturized soy protein (TSP) is whether to make it from expeller or Hi-Pro (Solvent meal).
Below is a breakdown of the main comparisons between the production of ExPress® vs Hi-Pro for making TSP:
|Capacity||500-750 lbs/hr||300-350 lbs/hr|
|Absorption Rate||3.2 to 4 times its weight in water||2.8 to 3.2 times its weight in water|
|Additives||Not Needed (around 50 PDI)||Normally Needed (low PDI, around 25)|
|Extruder Options||MS3000 Medium Shear Model (meat extender and chicken imitation pieces)
2000 High Shear Model (meat extender)
|Only 2000 high shear model (meat extender)|
|Market Limitations||None||Some markets less willing to purchase TSP made with hexane and additives|
|Ease of Use||Option of MS3000 is a more automated process||2000 with solvent meal may require extra cutter head on extruder barrel (if PDI is too low)|
|Boiler (gas connection)||Needed (Used for preconditioner)||Can use a mixer which does not require steam|
|Products||Preconditioner is located on top of the extruder, reducing footprint||Only meat extender (no shapes)|
|Footprint||Preconditioner is located on top of the extruder, reducing footprint||Mixer generally located in its own area, requiring more space|
|Control Panel||Touch Screen||Analog|
|TSP Color||Light to medium color||Tends to be lighter in color|
The ExPress® extrusion line with medium shear extrusion as it has the added benefits:
- Control of the whole quality chain process (from bean to TSP, controlling your meal)
- Insta-Pro extruders offer almost double the production capacity when using ExPress® instead of Hi-Pro as an ingredient
- Absorption rate much higher between 3.2 to 4 instead of 2.8 to 3.2
- Gives the option to use the MS3000 medium shear to make both type of TSP: extender & replacement.
