hello YouTube I know it's been a while
00:00:03.350 00:00:03.360 since we've been here together
00:00:05.690 00:00:05.700 Jill Fischer your friendly neighborhood
00:00:07.670 00:00:07.680 man skirt Breuer and welcome back a lots
00:00:11.419 00:00:11.429 changed here since you've last been in
00:00:14.390 00:00:14.400 the brewery I'll post a little video on
00:00:18.680 00:00:18.690 all of the changes that have happened
00:00:21.230 00:00:21.240 and maybe some upcoming changes but
00:00:23.960 00:00:23.970 today I have something for the tech
00:00:26.240 00:00:26.250 geeks out there we are going to break
00:00:30.200 00:00:30.210 down my heat exchanger and some home
00:00:34.040 00:00:34.050 brewers are familiar with plate chillers
00:00:37.010 00:00:37.020 or heat exchangers as we like to call
00:00:39.860 00:00:39.870 them here because they exchange heat and
00:00:42.250 00:00:42.260 I thought you'd like to see what's
00:00:44.119 00:00:44.129 inside mine so I'm gonna turn the camera
00:00:45.920 00:00:45.930 around for you OOP I think nope that was
00:00:50.029 00:00:50.039 not the right button oh please all right
00:00:53.900 00:00:53.910 here we are back at our front-facing
00:00:55.160 00:00:55.170 camera so this beautiful device here is
00:00:59.029 00:00:59.039 my heat exchanger and basically what
00:01:01.819 00:01:01.829 happens is the hot boiling sugar water
00:01:06.200 00:01:06.210 the work from the boil kettle gets
00:01:08.840 00:01:08.850 pumped into there it goes up and down
00:01:14.480 00:01:14.490 all the channels in these plates these
00:01:17.270 00:01:17.280 plates are cooled by water the second
00:01:19.910 00:01:19.920 stage is a little baby stage here is
00:01:21.440 00:01:21.450 cooled by glycol which comes from those
00:01:27.020 00:01:27.030 pipes which go to a chiller on the roof
00:01:30.859 00:01:30.869 through that wall right there and then
00:01:35.060 00:01:35.070 it comes out that valve there and then
00:01:38.210 00:01:38.220 goes over to one of the four fermenters
00:01:40.160 00:01:40.170 so basically boiling work goes in cold
00:01:45.649 00:01:45.659 work comes out I can get this down to
00:01:47.240 00:01:47.250 about 55 depending on the ground water
00:01:50.270 00:01:50.280 temperatures this is where the water
00:01:53.240 00:01:53.250 comes in here see we've got a little
00:01:55.850 00:01:55.860 charcoal filter over there Hackettstown
00:01:58.160 00:01:58.170 water is really nice for brewing so I
00:01:59.899 00:01:59.909 don't do much with it other than a
00:02:01.130 00:02:01.140 charcoal filter and yeah so I'm gonna
00:02:03.709 00:02:03.719 take this little bad boy apart today
00:02:05.179 00:02:05.189 because I managed to clog its solid with
00:02:07.039 00:02:07.049 hops which if you've ever used a heat
00:02:10.070 00:02:10.080 exchanger I'm sure you can relate to
00:02:12.170 00:02:12.180 that and we'll get going in a few
00:02:14.720 00:02:14.730 minutes first order of business is
00:02:18.170 00:02:18.180 getting everything unhooked and getting
00:02:20.990 00:02:21.000 it out where I can work on it curious
00:02:24.890 00:02:24.900 about that part can't really read it
00:02:26.690 00:02:26.700 sorry but that tells us when we put it
00:02:31.280 00:02:31.290 back together we have to tighten up the
00:02:33.949 00:02:33.959 nuts over here on these long stainless
00:02:37.070 00:02:37.080 steel bolts with tighten these nuts
00:02:39.860 00:02:39.870 evenly so the plate that presses the
00:02:42.680 00:02:42.690 stack to a certain thickness you can see
00:02:46.250 00:02:46.260 over here the beer work any port
00:02:52.490 00:02:52.500 it's a lot of hot junk in it so that's
00:02:55.850 00:02:55.860 why we're doing this all the side pieces
00:02:58.610 00:02:58.620 and parts are in there we're going to
00:02:59.840 00:02:59.850 put a little bit of hot water and
00:03:00.860 00:03:00.870 caustic cleaner in there basically like
00:03:04.640 00:03:04.650 a powdered brewery wash style of caustic
00:03:07.010 00:03:07.020 cleaner and get things cleaned up and
00:03:10.130 00:03:10.140 start opening this bad boy up here is
00:03:14.420 00:03:14.430 the tool well I mean here's the tool but
00:03:19.700 00:03:19.710 here's the other tool that we're going
00:03:21.290 00:03:21.300 to be using alright gang I'm gonna see
00:03:28.490 00:03:28.500 how well I can do this one-handed
00:03:30.110 00:03:30.120 I have loosened up all of the nuts you
00:03:34.940 00:03:34.950 can see that the stack is much wider
00:03:36.410 00:03:36.420 than when we started so the way this
00:03:44.120 00:03:44.130 works is it's got these little bushings
00:03:47.210 00:03:47.220 here that sit in these big bold step
00:03:57.570 00:03:57.580 we'll do that real quick I'm gonna start
00:04:10.230 00:04:10.240 in your YouTube channel we're gonna call
00:04:11.550 00:04:11.560 this the left-handed mechanic because
00:04:15.060 00:04:15.070 the right hand is always holding the
00:04:16.410 00:04:16.420 camera one of the fun parts about owning
00:04:25.710 00:04:25.720 and operating small brewery getting to
00:04:28.170 00:04:28.180 do all this fun maintenance yourself
00:04:29.550 00:04:29.560 play with these neat toys okay
00:04:40.140 00:04:40.150 look at that it's an accordion
00:04:47.919 00:04:47.929 um
00:04:53.189 00:04:53.199 so you can see that there are gaskets to
00:04:59.999 00:05:00.009 keep the water channels separate from
00:05:05.489 00:05:05.499 the work channels
00:05:09.619 00:05:09.629 and this was the reason that this is so
00:05:12.350 00:05:12.360 filthy is because it was clogged so
00:05:15.260 00:05:15.270 badly sorry maybe you can't hear with my
00:05:18.079 00:05:18.089 hand over the microphone the reason that
00:05:19.549 00:05:19.559 this is so dirty is because it was
00:05:21.769 00:05:21.779 clogged badly enough that I couldn't
00:05:23.689 00:05:23.699 even run cleaner through and I couldn't
00:05:25.369 00:05:25.379 get any liquid to pass through it so at
00:05:28.159 00:05:28.169 some point these channels got completely
00:05:30.109 00:05:30.119 plugged up so I've bought a filter a
00:05:31.929 00:05:31.939 pre-filter that I'm going to start using
00:05:34.989 00:05:34.999 to try to prevent that but you can see
00:05:38.199 00:05:38.209 worth water work water
00:05:43.939 00:05:43.949 Yatta Yatta Yatta all the way down so I
00:05:48.920 00:05:48.930 have to clean out all of these channels
00:05:51.170 00:05:51.180 each of these plates individually
00:05:54.369 00:05:54.379 without making too much of a mess and
00:05:58.119 00:05:58.129 then we can start putting it back
00:06:00.739 00:06:00.749 together when you put it back together
00:06:02.239 00:06:02.249 you have to make sure all of these
00:06:04.339 00:06:04.349 gaskets are properly in the channels
00:06:07.489 00:06:07.499 this little lip they get hooked on to
00:06:10.339 00:06:10.349 the side here it's kind of hard to see
00:06:12.230 00:06:12.240 but there's like a little little finger
00:06:15.469 00:06:15.479 on there it's a little finger and that
00:06:17.629 00:06:17.639 gets hooked into the little pleat I
00:06:21.230 00:06:21.240 guess you would say the corrugation and
00:06:23.920 00:06:23.930 then we'll do the same thing over here
00:06:26.059 00:06:26.069 for the this is the glycol side of
00:06:27.679 00:06:27.689 things right now everything's kind of
00:06:31.009 00:06:31.019 stuck in place so I have to open it all
00:06:32.359 00:06:32.369 up
00:07:24.960 00:07:24.970 [Music]
00:07:44.380 00:07:44.390 00:08:02.760 00:08:02.770 one more quick peek for you while this
00:08:05.320 00:08:05.330 whole things apart so this is a
00:08:07.390 00:08:07.400 two-stage heat exchanger and the first
00:08:10.420 00:08:10.430 stage is the water stage we were talking
00:08:12.159 00:08:12.169 about before media one in so the water
00:08:15.309 00:08:15.319 goes in here
00:08:16.149 00:08:16.159 and then this side is blocked off
00:08:18.879 00:08:18.889 there's gonna be a plate against here
00:08:20.890 00:08:20.900 with a closed face so the water is going
00:08:23.860 00:08:23.870 to look this way up and down up and down
00:08:25.270 00:08:25.280 up and down up and down up and down the
00:08:26.499 00:08:26.509 plates it's gonna come out down there I
00:08:29.740 00:08:29.750 don't have the tube in yet and it goes
00:08:32.680 00:08:32.690 back to the hot liquor tank where we
00:08:34.480 00:08:34.490 capture the hot water for reuse later
00:08:36.159 00:08:36.169 and then on this side you remember we
00:08:39.670 00:08:39.680 had that just a few plates here
00:08:42.430 00:08:42.440 so that's media 2 which is our glycol so
00:08:47.800 00:08:47.810 the glycol goes in there goes up and
00:08:49.810 00:08:49.820 down the plates comes back around and
00:08:51.639 00:08:51.649 comes back out in the front and then
00:08:54.220 00:08:54.230 goes back up those tubes to the glycol
00:08:57.699 00:08:57.709 chiller on the roof and this is the beer
00:09:01.120 00:09:01.130 outlet here the work
00:09:06.970 00:09:06.980 all right be right back
00:09:09.320 00:09:09.330 after painstakingly aligning each gasket
00:09:12.610 00:09:12.620 and making sure that each plate was put
00:09:15.590 00:09:15.600 back in the correct orientation this is
00:09:18.110 00:09:18.120 what we're left with I put the bolts
00:09:20.810 00:09:20.820 back on and now it's time to start
00:09:23.269 00:09:23.279 tightening them up we have to tighten
00:09:25.610 00:09:25.620 them down to about seven and
00:09:27.440 00:09:27.450 five-eighths inches according to the
00:09:29.449 00:09:29.459 front plate and right now we are at nine
00:09:34.790 00:09:34.800 in the half inches so we have to
00:09:37.100 00:09:37.110 compress this stack about two inches
00:09:39.980 00:09:39.990 along here and you can see from the
00:09:43.449 00:09:43.459 anti-seize on there that's where the nut
00:09:45.500 00:09:45.510 was last time so I got a little work to
00:09:47.840 00:09:47.850 do
00:09:48.290 00:09:48.300 the nuts have to be tightened up in a
00:09:52.430 00:09:52.440 star pattern much like putting a wheel
00:09:55.340 00:09:55.350 back on a car or tightening down a head
00:09:58.430 00:09:58.440 if you're an engine guy because you
00:10:02.240 00:10:02.250 don't want to warp the plates and
00:10:04.600 00:10:04.610 prevent everything from sealing properly
00:10:06.620 00:10:06.630 so I'm gonna get going on that and I'll
00:10:09.230 00:10:09.240 be back when I'm a little closer to done
00:10:11.780 00:10:11.790 and here we are all back together the
00:10:18.170 00:10:18.180 plates are compressed down seven and 7/8
00:10:20.690 00:10:20.700 inches which is right in the range that
00:10:24.620 00:10:24.630 we want so now I just the pressure test
00:10:27.350 00:10:27.360 it and put it back into service
