BrewZilla Generation 4 is the latest evolution in this series of RIMS breweries and has now become more flexible and powerful than ever. Although the exterior shape is largely the same, almost everything on the inside has been redesigned. The two big news are the new control unit with WiFi and Bluetooth as well as the concave bottom with built-in heating elements that implement Ultra Low Watt Density.The brewing process is still similar where you mash, leach and boil in the same vessel and the accompanying cooling coil means you can also cool the wort after boiling. During mashing, the wort is pumped around over the malt bed and then strained off and leached by lifting the malt basket up and placing it on the edge at the top of the pot.BrewZilla 35L Gen 4 RAPT Brewery Specifications:- Stainless construction- Detachable control unit with WiFi and Bluetooth connectivity- Programmable mash schedule with up to 6 steps- Ultra Low Watt Density heating element 3500 W- Malt barrel with removable bottom and feet in two levels for leaching- Stainless cooling coil- Volume graded pot- Magnetic pump at the bottom connected to ball valve and recirculation arm- Two upper and one lower handles for easier cleaning and handling- Brew volume max: 65 l- Maximum amount of malt: 18.5 kg- Height with recirculation arm mounted: 915 mm- Diameter: 406 mmComplete Concave Draining BaseThe new base design completely drains out meaning you capture every single bit of wort. No longer do you need to tilt the brewery to extract every last bit of wort. This also makes it suitable for CIP cleaning using our new Low Volume CIP Spray Rotor (KL04329).False Bottom Pump Protection ScreenOne of the key features of all the BrewZilla single vessel units is the false bottom protection screen. This screen avoids the need for doing a whirlpool and it filters wort and prevents more than 95% of hops and hot break getting sucked into the pump and thus greatly reduces the blocked pump issues that are often an issue with other brewery designs.Ultra Low Watt DensityThe BrewZilla has signficantly lower watt density than other breweries. The main benefit of lower watt densities are that it enables you to produce lighter colours of beers that would otherwise get some caramelisation. The ultra low watt density also means you have less chance of boil overs, you get less crud sticking to the element making cleaning easier and ultimately reduces wear and tear on the element meaning even with significant abuse your elements will last way longer.RAPT/Wifi ConnectedThe new Gen 4 model is the first BrewZilla that connects to the RAPT Portal (https://app.rapt.io/). This portal allows you to track, record and monitor your brews online. This greatly reduces the need for handwritten records of your brew day as it's all done automatically. The RAPT portal also allows you to see every brew you have done in the past and control the brewery remotely so you can start pre-heating water remotely or simply keep an eye on the brewing process while you do something else. Get push notifications to your mobile phone of when to add hops or start the boil. Along with this ease of access and control. The RAPT BrewZilla will also allow you to fully customise your brewday with profiles specifically tuned to your style of brewing or your recipe.For example you could set up your profile to receive certain alarms or messages when you are required to do something. E.g. Adding grain when the strike temperature is reached. Mash-Out Alarm when you're ready to sparge, Salt / Hop additions when you've reached the boil. As well as hop stand additions or chilling instructions. All of this at the touch of a button that is preprogrammed to what you want to do. No more egg timers, no more phone timers. Everything controlled by the one area.Bluetooth Gateway DeviceKegLand is currently developing various bluetooth devices such as KL24334 RAPT Bluetooth Thermometer (low energy BLE) other sensors which will be compatible with this brewery. This brewery is able to receive the BLE beacons and relay this information onto the RAPT portal. Also by receiving multiple BLE thermometer sensors the Brewery is able to make smater and more automated decisions on how to control the brewing or distillilation process. For example a BLE thermometer can be placed into your coolant water so you get an alarm if the temperature is too high, a BLE thermometer can be put into the middle of the malt pipe so you can more accurately control elements switching on/off to achieve a core malt pipe temperature etc.Improved Base Design with Easy Access PumpThe new base design means we have sealed all the electronics on the underside of the brewery into a separate junction box. This has allowed us to omit the bottom cover. This significant design change means that the pump can be accessed much more easily. It also means the plumbing can be changed more easily too. For instance you can re-arrange the plumping to the pump to pump into the tap outlet or change this so the tap outlet bypasses the pump. These changes make it more flexible but also much easier to take apart the pump for cleaning and maintenance if required.RAPT Controller with Full Colour ScreenThe new RAPT controller has an easy to read full colour screen. The controller can also be disconnected easily making wash down easier. The controller is mounted in a higher position with a tilting frame so you can angle the screen toward you depending on how tall you are. The new controller module is packed with features and KegLand is consistently updating firmware to include more features. Firmware updates are quick and painless and with a single click you can upgrade all Gen 4 units to the latest firmware to take advantage of new features and accessories. Forget getting on your knees mid-brew, do it all while standing or sitting next to your BrewZilla.The controller can also activate the pump. Meaning there are no toggle switches anywhere on the BrewZilla Gen 4.IEC Cable for Easy StorageThe new design has a removable IEC cable so you can unplug the cable making it more neat for storage.Improved Lid HandlesThe new lid handles are better designed and made from stainless so they are more robust and more ergonomic to hold especially with wet hands.Two Stage Oversized Malt PipeThis new malt pipe design is 30% larger meaning you can mash more grains and either make more beer or make higher gravity beers. the new malt pipe also has a two stage height adjustment so you hand half lift the malt pipe and set on the supporting halo ring halfway up. This makes it more ergonomical so you can lift the heavy malt pipe up in two stages but has the second advantage that it makes the brewery more suitable for smaller batches too where raising the malt pipe half way up is preferable.
