4 cleaning methods for fermenters

Analysis: 4 kinds of cleaning methods for fermenters

Fermentation tanks are widely used in dairy, beverage, bioengineering, pharmaceutical, fine chemical and other industries. The tanks are provided with interlayers, insulation layers, heating, cooling and heat preservation. The tank body and the upper and lower filling heads (or the prototype) are processed by spinning R angle. The inner wall of the tank is mirror-polished and has no sanitary corners. The fully enclosed design ensures that the materials are always mixed and fermented without pollution. The equipment is equipped with air. Breathing holes, CIP cleaning nozzles, manholes and other devices. However, the correct cleaning method for fermenters is not understood by many people. The following is explained by Wenzhou Kexin Xiaobian, four correct cleaning methods for fermenters:

When the fermenter is fermented by natural yeast, it is cleaned, no residual tartar, mold can be used, no need to disinfect, pump and pipe are washed with high pressure water after each use.

When using commercial yeast fermentation, it should be rinsed and disinfected every time.

Option 1 Alkaline washing - pickling - disinfection

Sequence operation temperature time remarks

1. Exclude co2, rinse the residue with water to the water, drain at room temperature for about 5 minutes.

2. 1.5% NaOH plus 0.3% NaOH additive Normal temperature 40 points Recycling Rimalkan-AD

3. Rinse with clean water and drain at room temperature for about 5 minutes.

4. 1% acidic detergent Rimacid-SP5 30 minutes at room temperature

5. Rinse with clean water at room temperature for 5 minutes.

6. 0.3%-0.5% peracetic acid fungicide Weicoper is discharged or recycled at room temperature 10-20 minutes

7. Flush

Option 2 pickling - sterilization

1 Rinse the residue with water to the water for about 5 minutes.

2 Wash with 2% acidic detergent TC-Proktalan 40 points Recycling

3 Rinse with water, drain about 5 minutes

4 with 03%-05% peracetic acid fungicide Weicoper 10-20 points or back

5 rinse

Option 3:

Flushing - NaOH aqueous solution rinsing - citric acid aqueous solution rinsing - rinsing

Option 4:

Na2CO3 or NaOH aqueous solution rinse or spray rinse cycle
