Do you need an agitator in a hold and saddle tank or in bins and combos where your brine and marinade is held? As mentioned in previous issues, newer ingredients like soy, starch and carrageenan do not dissolve but soak up water and the other ingredients and once fully “hydrated” are heavier than water. Left un-agitated, the ingredients will sink and separate which will produce very inconsistent product. This will affect yields, color, purge and fluctuating pickups. How can this be prevented?
- Start with applying the correct agitator in the correct position in holding tanks that are sized to produce flow that...
- overcomes the settling velocity of the particles so separation does not occur
- does not create a vortex and entrain air and lastly...
- creates a flow velocity high enough so as not to get freeze on to the cold wall tank
Things to think about:
Consider ways to maintain uniform particle suspension in this tank. Remembering that left un-agitated, the hydrocolloids sink. One thing that we have recommended to injector companies is to place the return line from the hold tank or a heat exchanger so that the flow creates a sweeping flow across the bottom of the saddle tank. For those running the heaviest formulas like in Ham or Turkey, the addition of a small agitator in the saddle tank has solved the problem.
