Professional method of cleaning plate heat exchanger

Cleaning the plate heat exchanger, which is what we call cleaning, testing, and reinstalling the seal, can improve the heat exchange efficiency and service life of the heat exchanger through this process. The following is the cleaning of the heat exchanger in order to meet the requirements of cleanliness and hygiene during the processing of food, beverages and dairy products:

1. Remove the gasket.

Flushing the plate heat exchanger plates First, flush with high pressure, and then wash off the accumulated materials on the plates by hand. This is a whole step. In this process, after cleaning, it will directly affect the heat exchange efficiency.

2. Soak the plate.

Immerse the plate in a chemical solution that does not corrode to completely remove residual material. The type of chemical solution will vary depending on the actual accumulated material you want to remove, but there are many different mixtures you can choose from abrasive acids such as acrylic acid.

3. The dye experiment detects defects in the plates.

A customized dye spray gun can be used for fluorescent dyeing. After sufficient spraying and drying, the sheet can be placed in a dark room and inspected for any defects under black light, such as cracks, breaks, small holes, etc. Finding these defects during the test will eliminate future cross-contamination issues.

4. Find a rolling gasket heat exchanger rubber gasket groove throughout the evaluation process .

So that you can prevent resealing. If you ca n’t find the rolling gasket groove, you should replace the plate to avoid unexpected downtime.

5. Re-stick the adhesive gaskets.

Use adhesive or industrial glue to put the gasket back on the board. The type of adhesive used can refer to the instruction manual. Use the clear size of the plate to compress the rubber gasket into the plate groove.

6. Thermal maintenance.

The plates are processed in an industrial oven at a specific pressure recommended by the manufacturer. When the unit must be opened repeatedly during the operating cycle, the length of the heat-curable adhesive gasket is 10 times longer than the standard snap-on adhesive gasket.

7. Check for defects.

Check the flatness, firm adhesion, excess adhesive, and any general defects of the sheet adhesive gaskets.
