Milk Pasteuriser - Tetra Pak Tetra Therm Lacta CS-H15

Complete skid mounted Tetra Pak Tetra Therm Lacta CS-H15 dairy pasteurisation unit for continuous processing and pasteurisation of milk for market milk / cheese milk or yoghurt milk. The Tetra Therm Lacta is as standard automated to safeguard production. Main process sequences can be divided into the following main steps: pre-sterilistation / filling / production and circulation / intermediate cleaning / emptying and Cleaning-In-Place (CIP). Before production can commence it is necessary to sterilise the unit by circulating hot water for 20 minutes. After pre-sterilisation, the unit is cooled down and stabilised to production temperatures.When downstream equipment is ready, production can start.

The unit exist out of: open balance tank with floater for level control, product pump (Alfa Laval LKH-10/140 SSS 2,2 kW, 1996, serialnr 001534), Plate Heat Exchanger / PHE (Alfa Laval CLIP 8-RM, 5-sections, 1996, serialnr 30101-24479, pressure up to 10 bar, temperature up to 110 °C, volume: 358,5 liter) with regeneration sections (product is regeneratively pre-heated by the outgoing pasteurised product and later on cooled down by incoming product) and indirect hotwater set with brazed phe / steam valve and trap / expansion vessel for final heating to ensure even heating on the product (circulation pump Alfa Laval LKH-10/140 SSS 2,2 kW) / indirect water set with brazed phe / control valve for cooling (circulation pump Alfa Laval LKH-10/140 SSS 2,2 kW) and outfeed for separator / homogeniser and final ice water section for final cooling to reach the requested outlet temperature, feed pump to separators / homogeniser (Alfa Laval LKH-10/163 FSS 4,0 kW, 1996, serialnr 002698), booster pump to keep the pressure on the pasteurised side higher than on the non-pasteurised side (Alfa Laval LKH-10-/163 FSS 4,0 kW, 1996, serialnr 002324), holding tube of 15 seconds, flow diversion valve (automatic diversion of the product back to the balance tank when the pasteurisation temperature is too low), interconnecting piping / valves for product or utilities and stainless steel control panel with temperature recorder and operation controls.

Probable temperature cycle for this milk pasteurisation unit: 4 ° (inlet) - 55 / 60 ° (separator / standardisation / homogeniser) - 74 / 95 °C (pasteurisation) - 15 seconds (holding) - 4 / 28-32 / 43 °C (outlet). Heat regeneration of this PHE: ± 90 %.

Additional features:

The yoghurt holding of 300 seconds, mentioned on the P&ID is not available / excluded.
