SoftAcid P+
SoftAcid P+ is a patented mixture of propionic acid and modified lignosulphonic acids. This special combination considerably reduces the aggressiveness of propionic acid.
In comparison with pure propionic acid, SoftAcid P+ is only slightly corrosive and does not cause chemical burns in case of contact with the skin. SoftAcid P+ is not classified as a hazardous material.
Advantages of SoftAcid P+:
- Strongly inhibits mould
- 95% less corrosive than pure propionic acid
- Good taste
- Does not cause chemical burns
- Not a hazardous material
- Low pH value
- Less wear in warehouses, dosing and mixing plants, and stall equipment
- Improvement of the working conditions for grain preservation
- Lower steam pressure and thus lower acid losses in the crop
Recommended Dosage
For the acidification of grain (whole grains), we recommend dosages according to the following table:
| Moisture contain of the grains in % | Preservation period | |||
|---|---|---|---|---|
| 1 - 3 months | 3 - 6 months | bis 12 months | ||
| Up to 16 | 0,50 | 0,55 | 0,61 | |
| 16 - 18 | 0,55 | 0,61 | 0,72 | |
| 18 - 20 | 0,61 | 0,72 | 0,83 | |
| 20 - 22 | 0,72 | 0,83 | 0,94 | |
| 22 - 24 | 0,77 | 0,94 | 1,05 | |
| 24 - 26 | 0,88 | 1,05 | 1,16 | |
| 26 - 28 | 0,99 | 1,16 | 1,27 | |
| SoftAcid P+: Density (20°C) 1.075 g/cm3 | ||||
Recommended Uses
- Do not mix SoftAcid P+ with other acids or chemicals!
- Clean the grain before preservation.
- Existing dosing technology can be used insofar as it is acid-resistant and the recommended use of SoftAcid P+ is taken into consideration.
- For new acquisitions, contact the manufacturers of dosing technology.
- The pump must always be filled and should never run dry!
- Attach the non-return valve to the suction area to prevent pump from running empty and thus interrupting the dosing procedure.
- Coarse-mesh base filter (approx. 3 mm) on suction pipe.
- If present, remove the fine filter from the main filter.
- In comparison to pure propionic acid, SoftAcid P+ has a higher viscosity (7 – 10 mPas at 20˚C). For this reason, the capacity of the dosing unit should be gauged before the use of SoftAcid P+. In case of temperature fluctuations of more than 5˚C, the capacity of the dosing unit should be regauged to achieve the optimum application amount.
- Optimum application angle of the screw: 40 – 45 degrees.
- The mixing distance must amount to at least 3 m.
- For trough screws, at least four mixing elements must be installed along a length of 2 m.
- Nozzle size: approx. 3 mm (enlarge existing nozzles if required).
- A course spray is advantageous.
- Nozzle pressure: approx. 2 bar.
- Remove the overrun protector from the nozzles (balls) and attach a ball valve to cut off the nozzle connection if required.
- 40 t maximum preservation amount per hour.
- Thoroughly rinse the dosing unit and nozzles with water after every use, if possible with hot water. For preservation breaks during the day, do not let the pump run empty; that is, the pump should remain filled with SoftAcid P+.
- After preservation, rinse the grain feed screw several times with untreated grain.
