Q: My press doesn’t use water: Why do your presses have continuous water usage as the press runs and why can I not recycle it?
Let’s start by talking about how much water our presses use:
Our Kreuzmayr KEB 400, KEB 500, KEB 750 and KEB 1000 Single Belt Presses use approximately 90 gallons/hour of potable water, our KEB 1250 and K2B 750 use approximately 180 gallons/hour, and our largest Double Belt Presses use 360 gallons/hour.
How is the water used?
Our presses spray high pressure water across the belt after the fruit mash has been scraped off to remove sediment and particulate. This stops the screen belt from plugging up and and keeps yields high.

Fresh potable water is used in a Kreuzmayr press, keeping the pathogen count down. Using recycled water accumulates pathogens which can’t be removed through a simple filtration process. So the contaminated water would be sprayed onto the belt again and again, creating a pool of pathogens. Safety is of the utmost importance, that’s why we recommend to use fresh potable water!
Of course we offer recycling systems with high pressure pumps to reuse the water. This is used for businesses that have a very solid pre-wash procedure with parasitic acid and water rinse.
How important is it to you to keep your pathogen count down?
Quality control standards around food production may include a limited pathogen count. Pathogens are a food safety concern to processors of unpasteurized juices and ciders. According to The Canadian Food Inspection Agency (CFIA),
“The consumption of unpasteurized juices and ciders contaminated with pathogenic organisms, such as Escherichia, Salmonella and Cryptosporidium have been known to cause human illness. The young, the elderly and those in poor health are considered to be at higher risk.” Check out our selection of pasteurizers here.
