Nghiên cứu lựa chọn công nghệ và tự động hóa hệ thống thiết bị tách bia từ nấm men kết lắng sau lên men

The breweries produce excess yeast residues of ~ 2-3% by volume, about 50% of which can recover beer, the quality of the beer recovered is determined by the taste (autolysis). yeast cells, remaining yeast cells, O2 infections, microbial stability and filtration. The use of automation systems to minimize microbial contamination is a necessity in this research project we use Alfalfa’s high speed centrifuge BRUX 510 Continuous discharge system has the following benefits: Applied to brewery capacity of 1-10 million hl / year, high quality of beer recovery (high vitality of yeast, high filtration efficiency, O2 low, short return time (saving 1-1.5% of beer yield, high profit, low investment cost, energy saving) Easy operation and maintenance system Siemens PLC or Allen Bradley PLC, low operating and maintenance costs, direct CIP, small installation area: 5 m2. Rarely, a significant proportion (2%), from 100 liters after fermentation, usually receives about 2 liters of concentrated yeast. After sieving and washing, the remaining volume is 1.5 liters but only 0, 5 liters of which are used to ferment the batch, the remaining one liter is redundant. With the capacity of a plant is 10 million liters per year, the amount of excess biomass will be from 300 to 350 liters per day. Yeast beer contains a lot of protein, if not extract, this is a major source of pollution. Utilization of waste yeast residue of brewers has been and is in many countries around the world. Japan is the country that produces and utilizes the most waste yeasts and products containing yeast waste. In Japan yeast powder is classified in the group of natural spices. In Vietnam, by 2010, the average consumption is 28 liters / person / year. Total beer output in 2010 is 3 billion liters. With heavy beer production and emissions, most brewers sell to small producers. Absorption capacity of protein in animal waste yeast is low. Many factories have to rent waste yeast treatment units. The waste yeast has many applications in many different industries such as pharmaceuticals, nutritious foods, animal feeds with vitamins, enzymes, nucleic acids, glutathione, soluble protein fluids, aqueous extract of yeast …
