Notes of operating the plate heat exchanger in microbrewery
In microbrewery, before adding yeast to the wort, we should cool the wort via the plate heat exchaner. Here the the notes of operating the plate heat exchanger well:
1. Before wort cooling, the plate heat exchanger wort tunnel must be sanitized by circulated hot water of above 80℃ for no less than 30minutes. When the cooling starts, the wort should firstly drain out the water left in the tunnel before mixing with yeast or going into fermentation tank.
2. During the heat exchanging process, keep monitoring the inlets/outlets temperatures of wort and cold water/glycol water. Adjusting the flows in times via adjusting valves, and thus maintain the wort outlet temperature at expected recipe temperature (+_0.5℃), no big fluctuation. At the end of the cooling time, using hot water to push all the wort out of the piping.
3. The wort cooling time is best to be controlled within 60minutes. Over long time will effect the turnover of the whirlpool tun and the wort quality.
4. Regularly disassemble and clean the plates, as the cold sludge, hops and resin etc. will easily attach onto the plates and thus effect the cooling efficiency. After disassembling the plates, soaking the plates with the alkali liquid (1-2% concentration) and then brushing the fouling, and then washing with clean water.
5. The maximum work pressure of the plate heat exchanager is 1Mpa. There will be a pressure difference at the wort tunnel and water tunnel, Usually the common working pressure is 0.2-0.4Mpa. The over-high pressure difference will deformed the plates, and effect the sealing performance. So please take care of the pressure difference during operating.
