Karl Schnell 260 UHT 1500
Processed Cheese Cooker UHT Line
Ideal for processed cheese, suitable for IWS, triangle, and foil wrapped packaging.
Manufacturer: Karl Schnell GmbH & Co. KG, Germany.
Capacity of the line end product: 300/500/800/1.500 kg/h output.
Year of manufacturing: 2009-2012-2017
Including:
9. Buffer Tank
The buffer tank is used for temporary storage of processed cheese at elevated temperature prior to downstream processing or filling. The product is maintained at approximately 80 °C to preserve flowability and ensure hygienic conditions. This supports a continuous process flow, prevents temperature loss, and ensures consistent product quality during transfer to the next stage.
Equipment: Storage Silo 300 (Vorratssilo 300)
Volume: 300ltr
Year of Manufacture: 2012
Serial Number: 14618
Including:
• Feed pump to UHT, twin-screw type, suitable for production and CIP (1 pump).
• Level indication by loadcells.
• CIP cleanable
• Stark Conical tank, double jacketed for heating and cooling
• Heavy agitator, manhole, breather pipe, control panel, temperature sensor, piping and valves.
10. UHT unit
Capacity: 300-500-800-1.500kg/h
Year: 2012
The UHT system is used to heat the processed cheese from approximately 80 °C to a sterilization temperature of around 142 °C, followed by controlled cooling back to 80 °C. This high-temperature short-time treatment ensures microbiological stability and extends shelf life while preserving product quality. It enables aseptic or prolonged storage conditions and supports consistent, safe downstream processing and filling.
Equipment:
• 2 Direct steam injectors, inline mixer.
• Steam control valve, steam Filter and stop valve
• 2x2 = 4 Holding tubes with 3 temperature transmitters. (2 at begin, 1 at the end).
Diameter: 26mm, including swingbend panel to choose, short holding (at 300-500ltr) or long 7mtr holding (at 800 - 1.500ltr). This holding was renewed in 2024.

11. Creaming Tank 80 °C
The creaming tank is used to hold and condition the processed cheese at approximately 80 °C to allow the product to fully develop its final texture and consistency. During this stage, the cheese mass stabilizes and achieves a homogeneous structure.
Equipment:
Creaming Tank / Holding Tank for processed cheese, jacketed and insulated, equipped with agitator and control panel (Karl Schnell system)
Volume: 500ltr
The KS tank is replace in 2016 by an tank with an extra heavy agitator (make ABAB) to be able to handle cheese with an relative high total solids and viscosity.
