Achieve More Repeatability Using, PID, RAPT BLE Temp Probe and Heat Exchanger Dish

[@SimonBorg]

Definitely, the dish should be standard. It's a great bit of innovation and it's why I love kegland. Keep innovating and keep looking at ways to make your great products even better!

[@KegLand]

Yes we really feel the same thing. It would only increase the price slightly and really the brewery works quite a bit better with this dish. Either way we will also sell it separately for customers who have already purchased a Gen 4 model.

[@cleaverjc2]

My blue tooth thermometer and HDP just showed up and I'm so impressed with how well they work together. After playing around with recirculating water and tuning my PID settings, it makes so much sense to use a secondary thermometer. I was never really worried too much about my mash temps with my robo brew but I'm so much more confident with my gen 4 brewzilla system.

[@feronimus7723]

You should really include the CIP spray module inside the gen 4 kit. Buying most kegLand products in Europe is already a nightmare. Trying to purchase any of the extras, especially if they are not expensive, is almost impossible. Very few distributors from Europe have your products, even fewer ship outside their country or have an English site. Most are distributors only for the fermzilla line. Its just sad that the only way we can get our hands on these products is buy paying someone from AU to buy them for us and ship them to EU. The cost is very close to 1500-2000 euro just for the shipment most of the times.

[@janpcs]

That's why I will probably end up buying a GF when I really would like to buy a Brewzilla. It's next to impossible to get you hands on Kegland products in the Netherlands.

Being able to tweak the PID according to my needs, batch size and increasing flexibiliy and potential for accuracy even further by adding an optional temperature probe is a great thing! I believe other manufacturers would rather not trust their customers and not make these functions accessible. So... thanks for making it possible!

Just got my BZ 4.1 yesterday and I spent some time putting it together. I got the heat exchanger disc as well. Good thing I had watched a lot of YT videos on the set up since the only instructions in the box were how to line up the sight glass sticker. I assume that for the heat exchange disk, I just replace the center pull ring with the one that the disc came with but they look to be identical in length.

[@lifeafterwork]

Hell yea!! - Just getting ready to buy all my equipment and the Gen4 is top on the list. I don't want to go chasing up addon parts and makes the gen 4 more fully featured. Please add the CIP as well. Better to add too much rather than not enough. You could also make packages.

[@westcoastbestcoast7683]

You’ll be getting an order from me guys, fantastic stuff this. I have the gen 3 already and my only real issue was the temperature differential between the display with the probe at the bottom and when I took manual readings in the mash. I’d try and compensate manually to get the core mash temp exactly where I want it but this solves all my problems. Now just need to make up an excuse for my wife!

[@SammaxMunich]

I bought the HED now 3 months ago - it works very well. The PID algorithm works definitely more stable and sraight forward with the changed flow. I did notice another advantage with this dish: The risk of a boilover seems signinifcantly reduced! Especially at the beginning of the boil, it seems that the HED somehow impacts the boil pattern and the need for constant stirring is greatly reduce. Did not expect that! I definitely adds another 2 minutes to the cleaning procedure, but it is not as bad as i thought it would be.

[@KegLand]

Yes the HED is a great accessory and I enjoy using this for my step mash profiles in particular. For single infusion it's not really necessary but for step mash it's great.

[@devilmaycare2809]

After buying my gen 4 a month ago, why after the year this video has been out hasn't the heat exchange dish been added to the system as standard when you know it make the system work better??

[@KegLand]

We get about 60% of customers who are not doing step mashes and are happy to not use the HED. So we are worried about increasing the price of the base unit if not everyone needs the part. Even if we made it included it would be a similar price increase to purchasing it separately so it's not like you would get it for free. Definitely if you do step mashes it's much nicer to have the HED but it comes down to how you brew.

[@m8harry]

As a new brewer i look forward to purchasing this system very soon. Its my hope the clean in place ball and the heat exchanger dish become standard inclusions.

[@cristigheorghe2913]

Damn, I need a love button for this vid. I learned more about PID in these 30 mins than I did in my uni years. Regarding the heat exchanger bottom plate: I definitely believe it should be standard. I just bought a Gen 4.1 BZ in EU these days (Aug 2024) and it wasn't there. I wouldn't mind paying extra for the part, but in Europe spare parts are not easy to find. I'm also thinking the plate should help with whirlpooling by separating the cone and not sucking it in through the middle.

[@NoMusiciansInMusicAnymore]

Yeah I'll be getting one of those plates and definitely think it's something that should be included, same with the CIP. Thanks a lot for the PID walk through, the info you guys provide in the way you provide it is why I keep buying from you.

First time trying the heat exchanger dish after 15 brews without it. It makes a huge difference for just being a simple and cheap stamped plate, definitely wish this came with the unit. Now I can actually control the temperature, really had to babysit it and measure at the top. Now I'm also not so worried about destroying the enzymes, I used to hear the wort getting to hot on the elements, now it's silent even if the elements are on for more than 10 seconds because the wort passes over it better.

[@josephmichaud2396]

I think you should include the Heat Exchanger Dish with the Gen-4. As you say in the video the cost is small, with higher benefits. I purchased the Gen-4, 65 L unit over the past weekend, having the Heat Exchanger Dish included would have worth the small price increase. Trying to buy one will be hard as many dealers probably wont carry it. It would probably need to be specially ordered. YOU COULD RUN A SPECIAL DEAL WITH THE RAPT BLUETOOTH TEMPERATUNE PROBE! Buy the probe & heat exchanger dish together.

[@KegLand]

Yes I agree. We are going to make the dish standard in future.

[@KnobbyWobby]

Love these types of videos, the PID explanation was especially useful. The Brewzilla Gen 4 is amazing, though one small issue for me was, with the conical base giving you the option to do small scale batches, I find the immersion chiller will sit above the wort at 10L (post-boil). I wish it dropped in just a little bit lower as there's definitely room to do that.

[@KegLand]

The immersion chiller is the easiest chiller to use so it's good for people getting started but I personally prefer the counter flow chiller as its just a bit quicker and in Australia our water temp can get pretty high so it's also better in that respect.

[@theslyrylan]

Ended up getting both of these. Excited to try it out!

I just ordered the GEN 465 L on the black Friday sale. A real bonus would’ve have been to have included the heat exchange plate.

[@mrknaldhat]

I'm now 3 brews in with the gen4-35L and I'm really frustrated about the inconsistent temperature. I have now cut out a similar piece from a plastic bucket lid and it's already MUCH better. Previously very poor efficiency, 50-60%, too low OG and too high FG due to poor starch saccharification. This dish is a MUST in my opinion. It's really a design flaw. But we want big heating elements and the ability to drain from the bottom! Kudos for allowing that! (I've always had ~70% or better mash eff on a GF30. I almost always use rice hulls, ensure good recirculation, adjust pH and water mineral content. I can hardly think of anything else to optimize)

[@mrknaldhat]

and I've also insulated the tube on the side and the recirculation arm to not lose any heat there either. And ensure at least 45 mins mash time, often more than 1h

I think the addition of the HED makes good sense. I think it is odd that the immersion chiller is part of the Brewzilla set, but WITHOUT the fittings needed to connect it. I wish the immersion chiller was an option and that this option included the fittings. So in with the HED and out with the immersion chiller and correct the pricetag. Other than that the gen 4 is a great boiler.

[@icemanknobby]

If this is implemented that I think is a must, when would you be including or when would this part be available. I am just about to order a Gen 4 in Thailand it would be very unlikely they would stock this as a spare part, if included I would wait I guess, but when?

[@pavonino]

Hey Kegland, there is a problem in your PID algorithm, and you can see it in your video at 8:52, the temperature cutout is not disabled in PID mode so when you hit your setpoint the power clicks off and on resulting in higher output and overshooting. The comment about hysteresis not applying in PID mode should be true but in the current firmware The hysteresis still applies and will turn off heat until temperature drops by the hysteresis value.

[@KegLand]

Even with a 32a circuit breaker you would be falling a bit short. You need about 50amp.

[@cristigheorghe2913]

Just purchased the HED (heat exchanger dish) after seeing the praise it got in the vid, and to my sad surprise, whenever I screw on the plate, the pump protector screen becomes massively warped. I did install the longer bolt the dish came with, and even tried fiddling with some extra washers in between but to no avail :( Worth mentioning that the false bottom that came with my Gen4 Unit only has one ring grab in the center, as opposed to two of them like in the video, and seems less sturdy than the one depicted here.

Why not simply add an aux temp probe jack on the side of the Brewzilla rather than having to deal with the added complexity and cost of the bluetooth sender?

That is a fair point. We could do that. It was spoken about in the office so it's possible this may happen in the future.

[@thebackyardbrewer5611]

Can you allow customisation of the brewzilla kit on your website? Firstly so you can opt for a counter flow chiller instead of another useless immersion chiller. Most of us already have a stack of those taking up space in our breweries. Or even to buy it bare bones with no chiller or mash paddle or any other thing that we probably already own! Also it would be good to all the buyer to add other items that are Brewzilla specific on the actual brewzill page. That would make it so much easier to buy the right specific accessories without having to look at multiple items.

[@KegLand]

This is a fair point. I will talk to the team about this. I know a lot of people do not bother with the immersion chiller so it's possible we can take this out of the kit.

This should definitely be as standard, especially since the thermometer will be more accurate(but we need a way to know which version we have). I agree with other comments, it would be awesome to have an european warehouse :) Regarding the PID, my current material(home-made, with craft-beer pi installed) is able to do some "automatic calibration", I've to fill it to my desired level, then it runs through a long process where it overshoot and basically does what you explained, to compute for us some appropriate parameters. Wouldn't that be easier?

Thanks for bringing this up. This is something that we are going to change soon. Right now when you power up the Brewzilla it will return to the previous settings. Normally before we pack these up in box we turn them on to full power but that means that when you have a new unit it will automatically go right up to full power when you turn it on and that this is not a good idea. As a result we are going to change the firmware so when you power on the unit it will require you to "confirm" if you want to continue from the previous settings.

I guess I need to play with PID a little, although some people also advise not to use PID at all and instead manually adjust settings, something that defeats the purpose of having a fully automated system.

[@KegLand]

Always use the top plate. Helps with sparging evenly and dramatically reduces the chances of blocking the pump. We tend to not use PID - a RAPT BLE probe is a better option IMO

This looks like a good idea given the location of the probe. Would it be possible to get a drawing of the item for people in Europe who have already purchased a unit? Dishing it would be tricky but it definitely looks possible to make one. Thanks.

To be honest we did the original testing with flat sheet and this worked fine. You can literally just cut out a sheet of flat stainless and this works pretty well too.

Could you explain exactly what the "heating hysteresis" setting does? Is it a delta T window, allowing +/- the set temperature error from the set point. Is it preventing the heating element from turning on when the temp is not at least below the set temp. Or something else?

Yes that is what the heating hysteresis does. It is how much the temperature can deviate before turning the heating on.

Actually, the more I read others' experiences and see more videos, I can't bring myself to buy a BZ Gen4 until the HED is available in the U.S.. Again, it really seems like it is required kit to manage your mash, so I really hope that the HED is included in the future. Until then...waiting.

Heat exhanger plate looks like a great idea at the mash, how does it behave during the boil? - is there a risk of the plate/screen combo being lifted by the boil action?

[@fluffymatt9239]

This is something I was about to ask. If say it did effect it then they could always added mesh like qualities to it but not directly in the center which would allow the wort to flow outwards but also give the boil more surface area to penetrate

[@KegLand]

It operates in the same way. The bubbles in the boil just go around the edges of this plate so it's not an issue.

[@silveraven1]

I am currently awaiting my 65 L GEN 4 220v from the US because no Canadian retailers will carry them?!? . I really like how keg land keeps updating the technology to create more innovative products. However, living across the pond it’s harder to get separate equipment. For example, I’m still waiting for that silly little CIP attachment to be available. I recommend including all the equipment in one shot and charging a little more. Release a model that includes the distilling, lid, sight glass pipe, whirlpool arm, etc.. 😂 ONE AND DONE MATE! Thanks for listening to my rant.

[@KegLand]

Sorry Canada is a bit slow as your electrical approvals are often quite a bit more involved.

[@silveraven1]

@@KegLand I side stepped the bs and imported from the states. Did my first brew yesterday! Your supplier here in Canada OBK is not my favorite to deal with either anyhow.

[@TheFrankonia83]

A curious question: The probe essentially is only useful when mashing. Do i have to switch of Bluetooth before boiling or can i dump the probe inside the boil? Also: If i want to tighten the plate with the wingnut it totally bends the bottom filter to the point that it wouldn't flow on one side of the filter.

[@KegLand]

Just switch the temp probe from BLuetooth to built in when you get to the boil stage.

[@warrensomerville4573]

Yes add plate and spray unit as standard

[@petedudley1]

One potential issue with the heat exchanger dish is that it might denature more enzymes in the mash. If more of the wort is forced into close contact with the elements, even if the elements are low density, you might overheat the wort as it recirculates. The price of more efficient heating might be less efficient conversion of the starches, and as lower mash efficiency. Have you tested this?

[@KegLand]

We have not experienced this issue. The heat exchanger dish draws more heat out of the elements so we have noticed that the elements actually run cooler due to the heat being drawn out of them more efficiently

[@KieranShort]

Hell yeah, I'd love the screen to be standard.

[@johndonovan3353]

So far it looks like a great idea.

[@KegLand]

Thanks John. We appreciate it.

[@antoniomartinez493]

Is there any potential issues with superheated wort under the screen given the smaller gap between it and the elements?

[@KegLand]

That's why we have the temperature probe in this small gap between the elements and the screen. As soon as the probe picks up on the temperature increase it will turn the elements off if it gets too hot.

[@pawwaldner8628]

Can you connect Android phone to the Rapt controller using bluetooth??

[@KegLand]

The current Android and Iphone app is only to view the RAPT website but we are working on a new app that can communicate with the devices directly.

[@NixCM]

@kegland what do I do if my thermometer is like 9 degrees (C) too high? i cant calibrate it, do I set my mash temp that much higher? seems iffy

[@KegLand]

That sounds a bit strange as these are already calibrated before we send them out. IF you see a 9C difference it's probably more likely that the temp is actually different between the two probes. One is mounted into the base of the brewery and depending where you insert the probe it's not uncommon to have 9C difference in the one brewery.

[@NixCM]

it says my body temp is 42 C, i tested against another thermometer I had also, kind of unusable :(@@KegLand

[@travisdefalco4546]

When can we get these accessories in the US?

[@KegLand]

please contact our distributors in USA and they can hopefully give you the arrival date for accessories. Please contact www.morebeer.com or www.williamsbrewing.com

[@Mr-Cippy]

Is the plate coming with the Gen 4 now? If not, where can I buy one?

[@KegLand]

This is planned to happen but it's not implemented yet.

[@Dayman.]

Will I be able to use another bluetooth thermometer with the Gen4? And if so, what do criteria does that thermometer need to fulfill? I think having the heat exchange plate as a default is a good way to go if you keep selling the Gen3 models as well. The Gen4 seems to be more of a "premium version" of the Gen3 and as such is a product for those with more disposable income, adding this plate for a small price increse seems to fit with that imo.

[@KegLand]

No we have made our unit to only work with our thermometer. It would require a complete firmware re-design to use other BLE thermometers.

[@melkyriakou1555]

Thanks Kee, top stuff, loved the PID lesson. I am not fully sold on all the stuff, don't like cleaning too many bits and pieces, and I actually find the Gen 4 to heat up fast enough on just standard 10 amp power. I use a neoprene jacket from a Gen 3 which I've stretched around to fit. Not sure if that makes much difference, but in my testing with a temp probe in the mash, the temp differential with the built in bottom probe during recirculation is surprisingly bugger all anyway. Also, you know what would be cool, integration with brewfather during a brew (like grainfather with their app). Any chance? Not a massive deal, but I am usually running around doing other stuff (kids and wife related) during a brew day so it would help for sure.

[@KegLand]

Hey Mel. We have already done some integration with BrewFather but I would agree that it would be great if we had live updates so you can look at the brewfather display panel as you brew. This has already been spoken about and it's likely this will be available soon.

[@RolyNZ]

@@KegLand Any update on brewfather integration? I take it Brewfather is a separate entity to you guys so you can't make it hapen, but I would love a bit of flash App/recipe/BZ4 integration + control, not a dealbreaker, but my mates original Grainfather with a bluetooth controller is so sweet with the app control. (I win with on the gear stakes with the central drain and the mash pipe with the holes up the sides!!)

[@angrydutchman8590]

Uhmmm . . . hell yes, the dish should be standard (and please kindly include it before Gen4 ships)! It's a great how everyone at Kegland continues to refine, innovate and develop their products . . . it's far better than planned obsolescence!

[@andrewlambert9946]

Is it standard now? I just purchased one and asked for it as an extra… don’t need two :)

[@humbertotrevino]

When can I get the diversion plate??

[@KegLand]

This will be on the website soon. We should have stock in about 5-6 weeks from now.
