The lauter tun is an important part of the beer brewing system. A false bottom is installed. The plate supports the grain trough and the wort is filtered.
In the past few decades, the structure and working methods of the lauter tun have been improved in the craft brewery. WEMAC combined with many years of customer experience will introduce the characteristics of the new lauter tun.
①The false bottom structure of the lauter tun has been improved, and the opening rate has been increased from the traditional 12% to 15-18%, which shortens the filtration time.
②A nozzle for cleaning the filter tank is installed between the false bottom and the bottom of the tank, which can thoroughly clean the tank. The number of backwash water pipes is increased from 1 to 1.5 to 1.8. The impact of CIP cleaning is strong, making the cleaning thoroughly clean.
③The density of wort filtering pipes has been increased from 1.1 to 1.2 per m21.
④Every 3~4 wort filter tubes are set as a group, and they are controlled separately, and the flow is controlled by the online instrument to avoid the hardening of the grains and the appearance of vacuum.
⑤Use the balance tank to control the level of the filtered wort and the operation of the wort pump, and send the wort to the boiling pot or the wort storage tank smoothly.
⑥The cultivator has increased from double arms to 4-6 arms, and the tillage knives have been increased from 0.9/m2 to 1.1-1.2/m2. Different tillage arms have different types of stirrer knives, and the tillage can reach vertical and horizontal levels. Operation methods such as lifting and lowering can realize continuous tillage and washing of lees, keeping the turbidity of wort below 10 EBC units, and making the lees faster.
⑦In order to control the oxidation of the filtration process, the mash enters from the bottom, and the return wort enters from the side under the liquid surface. At the same time, the entire filter tank has good airtightness and can be filled with CO2 or N2 gas as a protective layer.
⑧The thickness of the wheat grains layer can be increased to 28~38cm, and the filtration efficiency can be improved.
⑨The amount of outflow of wort and the amount of lees water can be measured, and the pH and temperature of the lees water can be automatically adjusted.
Learning the characteristics of beer brewing can help us better grasp the brewing technology and improve the quality of beer. Breweries can gain higher commercial value.
Commercial beer equipment is at the heart of the modern brewing industry. This article will look at 2000 liter commercial beer equipment, a moderately sized brewing system suitable for small to medium sized bars, restaurants and breweries. We'll learn about its key components, operational processes, and the business considerations associated with them.

Restaurant Nano Brewery Equipment typically consists of a mash tun, brew kettle, and fermenter. The size of the brewing system will depend on the amount of beer you plan to brew, but for a restaurant nano brewery, a 1- or 2-barrel system is common.
More >>Craft brewery equipment is widely used in medium breweries and beer pubs. It can brew pale lager, amber lager, dark lager, ale and etc at proper temperature with different raw material.
More >>A complete set of 500L beer equipment consists of malt crushing system, saccharification system, fermentation system, steam system, refrigeration system, CIP cleaning system, pipeline system, etc. 500L brewing beer equipment is generally used in commercial, restaurants, bars, barbecue shops and other places.
More >>100L beer equipment can be used in home brewing and business. Each batch can produce 100L beer, and two batches can be made every day, up to 200L beer. If you are at home, you can produce beer every few days. If it is commercial, first of all, it is necessary to determine how many liters of beer are produced a day. The 100L beer equipment can produce up to three batches a day, but considering the labor intensity, it can produce up to one or two batches a day. The number of fermentation tanks is determined according to the amount of beer produced.
More >>Small beer equipment is generally divided into two types, one is small household simple equipment, and the other is commercial beer equipment. Small household simple equipment generally refers to 30l-100l, with small floor area, convenient operation and relatively simple technology. Commercial beer equipment generally refers to 300l-2000l beer equipment. Now the popular fine brewing beer equipment in the market is made with this equipment.
More >>The 100L micro beer equipment belongs to a small beer brewing system. Small space, high degree of automation, simple and easy to operate. The mash process is electric heating, which is generally equipped with two device specifications (mashing+lautering + boiling+whirlpool), with ice water tank, plate heat exchanger, wort oxygenator, wort pump, etc; The fermentation process is automatically controlled by PLC, and 6 fermentation tanks are generally configured according to the standard. It belongs to self entertainment beer brewing equipment.
More >>If you are planning to build a brewery, you must consider the turnkey beer project. What is the whole turnkey beer production line like? Which manufacturers can do a good job in this beer production line? What problems should we pay attention to? The beginning of a new project certainly requires a lot of preparatory work and a lot of problems. Many times, it is very difficult. This professional problem should be solved by a professional company. We can provide you with the turnkey work of the whole beer project, with more than 60 years of production experience.
