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-sterilizationProductionAseptic 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.Standard temperature programs for white milk: 5 - 80 - 140 - holding 4 seconds - 81 - homogenization - 20/25°C.The current line existing out of:High Pressure HomogeniserManufacturer: Tetra PakModel: Tetra Alex 400Capacity: up to 15.000 ltr/h @ 400 barYear: 2016Serial number: 5871116178Motor: 400 V - 50 Hz - 340 A - 200 kW - 1.488 rpmParts of the homogeniser block
