탱크의 음영 영역을 100% 세척하여 치즈 생산을 보호
스칸디나비아의 대규모 유제품 제조업체는 우유 공급을 확대하여 치즈 생산을 늘리기 위해 숙련된 탱크 및 시스템 건설업체인 베리텍 그룹에 도움을 요청했습니다. 이 업체는 바닥에 교반기가 장착된 30미터 높이의 새로운 원유 사일로 2대의 전 범위를 완벽하게 청소할 수 있는 설비를 원했고, 베리텍은 탱크의 음영 영역을 완벽하게 청소하기 위해 넓은 중앙 슬롯이 있는 알파라발의 PlusClean® 청소 장치와, 함께 사용할 알파라발의 상단 장착형 탱크 청소 장치를 추천했습니다. 상단 장착형 세척 장치와 함께 사용하면 PlusClean은 100% 탱크 세척 범위, 물과 세척제 비용 최대 80% 절감, 제품의 오염 방지를 보장하기 때문입니다.
날짜 2024-06-10A higher level of hygiene
To ensure food safety and no product contamination in the milk reception tanks, Beritech recommended Alfa Laval top-mounted cleaning devices and PlusClean cleaning devices. The PlusClean targets shadow areas underneath the agitator blades, where cleaning by direct jet impact from the top-mounted tank cleaning devices is not possible although indirect surface wetting takes place.
Eliminating contamination risks
In the past, the dairy had to compromise on its hygienic standards and sustainability goals to ensure sufficient cleaning coverage, using tank cleaning devices that were completely submerged in the product. This meant compromising on sustainability because these cleaning devices require operation at high flow rates. In addition, they are not fully drainable or self-cleaning, posing the risks of blockage and of creating new shadow areas. Moreover, maintenance of these devices requires tank entry by a service technician. In contrast, the PlusClean together with the top mounted cleaning device provides 100% cleaning coverage. Engineered to clean shadow areas that other tank cleaning devices miss, it ensures that no residue or microbes remain on surfaces underneath the agitator blades. Unlike maintenance for static spray balls and rotary spray heads, the PlusClean is integrated into the tank walls or bottom and has no moving parts inside the tank. All maintenance takes place outside the tank.
The Alfa Laval PlusClean® cleaning device is installed flush with the tank wall or bottom. It provides 100% cleaning coverage, up to 80% savings in water and cleaning media, and no product contamination.
Worry-free hygiene with cleaning validation
To validate hygienic process conditions after cleaning, the dairy conducted swab tests to validate tank cleaning. Test results confirmed that there were no contaminants or biofilm build-up on the backsides of agitator blades.
Faster, precision tank cleaning
Two minutes of every main CIP cycle is all it takes for the PlusClean’s dedicated, high-impact spray fan to remove all contaminants from the backsides of the agitator blades. While the blades rotate at 40% of the regular operating speed, the cleaning devices perform their duty, hitting the underneath of the blades with direct high-impact jet spray.
Complete cleaning coverage, measurable savings, and no product contamination. That’s true customer value. We always aim to optimize customer processes, increase productivity, and ensure food safety and quality.” Bent Larsen, CEO, Beritech Group, Alfa Laval Authorized Service Partner.
Up to 80% savings in water and cleaning media
Because the high-impact spray fan hits the shadow areas during a short period of time, very little water and cleaning media goes to waste. Compared to static spray ball and rotary spray head technologies, the Alfa Laval PlusClean cleaning device cuts water and cleaning media consumption by up to 80% thanks to optimized operating pressure and flow rates. These savings help the dairy achieve its sustainability goals.
Fast return on investment, low total cost of ownership
Low capital costs, low operating costs and low maintenance requirements ensure fast return on investment. After being activated more than 1,000 times, the PlusClean continues to safeguard process and product safety and boost productivity on the dairy’s cheese production lines.
