Brewhouse Reference¶
FUERST WIACEK Krones CombiCube 20 hl — as-delivered equipment specification
This page documents the as-delivered 2020 specification of the brewhouse, taken from Krones AG offer 27614973, dated 25.03.2020, „LIEFERUMFANG — SPEZIFIKATION, NEUBAU BRAUEREI 20 HL COMBICUBE".
Actual operating practice may differ from what is written here. Setpoints, volumes and timings on the floor have moved since commissioning. The SOPs — not this page — describe how the plant is run. Use this page for what the hardware is: diameters, areas, drive powers, nominal bores, design bases. Use the SOPs for what to do.
German equipment names are kept throughout, because that is what the Botec screens show. An English gloss follows on first use.
Note
Every spec block below cites its source page in the Lieferumfang, e.g. „(Lieferumfang p. 17)". Where the text extraction separated a label from its value and the pairing could not be resolved with certainty, this page says so rather than guessing. See Values Not Resolved at the end.

| Schrotmühle (mill) | 2-Walzen-Mühle (2-roll), model 16/16 R |
| Walzendurchmesser / -länge (roll dia. / length) | 160 mm / 160 mm |
| Schrotwalzenantrieb (roll drive) | N = 1,50 kW |
| Rated throughput as printed | 250 kg/h — but the adjacent „Produkt" line reads Rohfrucht (Gerste, Reis, Bruchreis), not malt. See caution below. |
| Mühleneinlaufbehälter (mill inlet hopper) | 16/16 R |
| Magnetkasten (magnet box) | 16/16 R, between inlet hopper and mill |
| Zellenradschleuse (rotary valve) | ZRD 150, flanged directly onto the mill |
| Malzschrotbehälter (grist case) | 650 kg, sheet-steel, pressure-shock-resistant and flame-transmission-proof |

Warning
The mill throughput is not unambiguous in the Lieferumfang. Two capacity lines sit close together in the extraction: „Leistung 250 kg/h · Produkt: Rohfrucht" (which reads like a catalogue line for raw grain, not malt) and „Leistung 1 t/h · Produkt: Malz" next to the grist case and its discharge screw. Do not plan a milling window from either number without checking the machine plate.

2.3 Läuterbottich — Lauter Tun¶
(Lieferumfang pp. 17–21. This is the most fully specified vessel in the document.)
Main dimensions and operating data (p. 17)¶
| Spec | Value |
|---|---|
| Durchmesser innen (inner diameter) | 2.000 mm |
| Grundfläche (floor area) | 3,14 m² |
| Volumen brutto (to Zargenoberkante) | 55 hl |
| Volumen netto | 18 hl |
| Höhe Gesamt (incl. substructure) | 4.230 mm |
| Podesthöhe | 3.000 mm |

Warning
174 kg/m² over 3,14 m² is the design bed loading — about 546 kg of grist (derived, not printed in the Lieferumfang). It is stated for Trockenschrot at 12 °P. Anything stronger, anything wetter-milled, and anything with a large adjunct or oat/wheat fraction sits outside the design basis. This is the number the runoff behaves against — a stuck bed is usually a loading or grist problem before it is a rake problem.

| Austreberdrehzahl max. (max. spent-grain-out speed) | 10,4 1/min |
A 100:1 speed range on one gearbox: the same machine creeps through the bed during runoff and spins out the spent grain at the end.
Hubgetriebe — lifting gear (p. 21)¶
| Spec | Value |
|---|---|
| Antriebsleistung (drive power) | 0,75 kW at 50 Hz |
| Antriebsdrehzahl (drive speed) | 33,4 1/min |
| Hubgeschwindigkeit (lift speed) | 233 mm/min |
| Ausstattung | Stellungsfernanzeige (remote position indication) |
| Bereichsendschalter (range endswitches) | 4 |
| Sicherheitsendschalter (safety endswitches) | 2 |
Warning
Six endswitches sit on the lifting gear — 4 range, 2 safety. The safety pair is the last line of defence against driving the rakes into the Senkboden. If a rake height fault appears on the Botec screen, treat it as a real endswitch event and check the mechanism; do not override.

Note
The stated operating data „beziehen sich auf den gereinigten Zustand des Kochers" — they assume a clean boiler. The 20-brew CIP interval and the 8,0 %/h evaporation figure belong together; evaporation falls as the tube bundle fouls.

(Lieferumfang p. 135)
Ground-floor water points with hoses and couplings: brass Spritzdüse with hose coupling on an aluminium wall bracket, ball valve, 2 × DN 20, hose length 25 m.
Values Not Resolved¶
The PDF text extraction separates labels from their values. Everything above was resolved by cross-checking against a second occurrence in the document (an insulation diameter, a section heading, a volume that matches the geometry) or against a physical calculation. The following could not be resolved and are recorded here rather than guessed:
| Item | Page | Problem |
|---|---|---|
| Mill throughput for malt | p. 9 | Two capacity lines, „250 kg/h · Produkt: Rohfrucht" and „1 t/h · Produkt: Malz". Neither can be tied unambiguously to the 16/16 R mill. |
| Austragschnecke motor rating | p. 10 | The item line reads „Austragschnecke DN150 3 m 0,55 kW" while a separate „Motor:" label carries 0,18 kW. Which is the installed motor is not clear. |
| Läuterbottich 0,10 kW frequency converter | p. 64 | Listed against the Läuterbottich but not attributed to any drive anywhere in the document. |
| Number of Läuterrohre | pp. 18–21 | 6 Ausläufe (Läuterrohranstiche) and 6 Sammelrohre are stated. „Läuterrohr Ø100 mm" carries no Anzahl — whether that is one pipe or six is not stated. |
| Glykol-Wassertank volume vs. geometry | pp. 92, 94 | 59,5 hl brutto does not reconcile with Ø1.600 mm × 4.000 mm insulated shell (~80 hl). Both figures printed as given. |
| Desinfektionswanne dimensions | p. 87 | Values 1.500 / 700 / 500 mm cannot be assigned to Länge / Breite / Höhe with confidence. |
| Rohrbrücke dimensions | p. 128 | Nine detached figures for Gesamt-Länge, Breite, Spannweite, H1, H2, pipe levels and three square-section material quantities. Only 3 Rohr-Ebenen is safe. |
| Steam flow temperature inconsistency | pp. 14, 55 | 3,5 bar is quoted as 148,0 °C at the Maischgefäß and 143,5 °C at the CIP heater. Printed as found. |
| Brauwasser-kalt insulation | pp. 35–36 | No insulation section exists for this tank. Whether it is genuinely uninsulated or simply omitted from the offer is not stated. |
| Läuterbottich hood/floor insulation | p. 21 | Only Zarge insulation is listed. No hood or floor insulation appears — not stated either way. |
