Tetra Pak Therm Aseptic VTIS 生产线

Tetra Pak Tetra Therm Aseptic VTIS line with Tetra Alex TA400 homogeniser. Aseptic processing unit for continuous UHT treatment with direct steam injection. Mainly for heat-sensitive low-acid products such as milk, enriched milk, cream, soy milk, formulated dairy products, ice-cream mix, dairy desserts as well as ESL (extended shelf life) products. Previously used in a milk factory in Europe., The unit is fully automated to safeguard the aseptic status while in production. The operation can be divided into four steps:, - Pre-sterilization, - Production, - Aseptic intermediate cleaning (AIC), - Cleaning in place (CIP), Before production can start, it is necessary to sterilize the aseptic area by circulating pressurized hot water. After sterilization, the unit is cooled down to production temperature. Finally, sterile water is circulated through the product circuit., Production starts by filling the unit with product via the balance tank. The product displaces the water/product mix to the drain or reject tank. A specially designed balance tank and valve arrangement minimizes the amount of mixed product., When an aseptic tank or filling machine is ready, production can start. The product is regeneratively pre-heated to about 80 °C in a Tetra Spiraflo tubular heat exchanger. Instant heating to sterilization temperature takes place in the steam injector by continuous injection of high pressure steam into the product., The product enters a holding tube where it is held at sterilization temperature for the required period of time. The product then enters the flash vessel where the pressure and temperature drop instantly. The excess water in the form of steam is flashed off., For optimal product stability, the product passes through an aseptic homogenizer before final cooling in the heat exchanger., Aseptic intermediate cleaning (AIC) can be performed to prolong the production time between full CIPs. When AIC is selected, the product is displaced by sterile water before cleaning starts. During the AIC sequences, the holding tube is kept at the sterilization temperature, thus keeping the aseptic parts of the unit sterile. The AIC can be performed either with lye only or lye and acid flush. After each production run, the unit undergoes CIP with both lye and acid. If the product supply fails or a stop at a filling machine occurs, the unit goes into sterile water circulation., Previously used for white milk and toddler milk., Temperature programs for white milk or toddler milk (8.000 / 11.000 ltr/h): 5 - 80 - 140/150 - holding 4 seconds - 81 - homogenization 65 °C - 20°C., The current line existing out of:, High Pressure Homogeniser, Manufacturer: Tetra Pak, Model: Tetra Alex 400, Capacity: 8.000 - 10.500 ltr/h @ 400 bar, Year: 2016, Serial number: 5871116178, Motor: 400 V - 50 Hz - 340 A - 200 kW - 1.488 rpm, Parts of the homogeniser block, 2x pistons, pulley on the drivework and hydraulic system are missing, see photos., Expansion vessel for flash cooling with built-in condenser, Manufacturer: Bujalski in the name of Tetra Pak, Model: ZBB-11-1, Year: 2016, Serial number: 160333, Capacity: 1.220 liter, Max. allowable pressure: 3,5 bar, Min. allowable pressure: -1,0 bar, Max. allowable temperature: 148 °C, Min. allowable temperature: 0 °C, Weight: 530 kg, Design code: EN-13445-3:2014, Skid 01 (CP11), - Centrifugal pump (Alfa Laval LKH-25, 11 kW, impellor 205 mm, serial nr: 199787)., - Centrifugal pump (Alfa Laval LKH-50, 15 kW, impellor 190 mm, serial nr: 200136)., - Flowplate., - Control panel (T5844130774, 3544-1264)., Skid 02 (CP51), Direct heating module with:, - Steam injector for direct heating of the product., - Centrifugal pump (Alfa Laval LKH-25, 15 kW, impellor 205 mm, serialnr 200788)., - Vacuum pump (SIHI, LEMB 161 8Z)., - Valves, pipes, fittings., - Control panel with regulator 01 and 02 (T5844130774, 3544-1264), Skid 03, Steam feed supply skid with 2x Samson valves and some additional piping and valves., Plate Heat Exchanger:, Manufacturer: Tetra Pak, Model: MS10-SM, Year: 2016, Serial number: 30109-16228, Volume: 250 liter, Pressure: 0/16,0 Bar, Temperature: 0/150 °C, Number of Sections: 2x, Plate heat exchanger for cooling of recirculating water for the condenser in the expansion vessel., Tubular Heat Exchanger 01, Manufacturer: Tetra Pak, Model: C-85, Year: 2016, Serial number: 1163426 01-21, Product: Fluid II, Design pressure PS Shell 0-16 bar and Tubes 0-40 bar, Design temperature Shell 0-180°C and Tubes 0-180°C, Volume Shell 352,4 liter and Tubes 243,4liter, Test pressure PT Shell 25,6 bar and Tubes 64 bar, Tubular Heat Exchanger 02, Manufacturer: Tetra Pak, Model: C-85, Year: 2019, Serial number: 1193240 01-11, Product: Fluid II, Design pressure PS Shell 0-20 bar and Tubes 0-40 bar, Design temperature Shell 0-180°C and Tubes 0-180°C, Volume Shell 187 liter and Tubes 126,6 liter, Test pressure PT Shell 32 bar and Tubes 64 bar, Excluded in the UHT:, - Product balance tank with level co...
