Continuous cooking system -Twinhead UHT
Lekkerkerker built its own continuous cooking system for heating processed cheese up to 140-145ºC, with 2 lines. The Twinhead has an automatic system in order to change from line 1 to line 2 without stopping. All this is also suitable for CIP. The unit has a capacity from 600 to 1,200 kg/hour.
Continuous cooking system consists of NEW components
- Closed buffer tank, suitable for CIP with level control.
- Supply pump, variable speed.
- 2 Steam injectors.
- Mix proof control valves for independent cleaning during production.
- Vacuum tank, vacuum pump.
- 3 Holding systems (holding tubes).
- Tube cooler.
- Discharge pump, variable speed.
- Centrifugal pumping for cleaning.
- Tank for steam heating for cleaning.
- Electric control cabinet with Siemens PLC and Touch screen control unit.
- Fully assembled on SS frame.
Options of the continuous cooker
- Creaming tank with pumps.
- All piping double-walled at product supply and discharge in order to prevent clotting.
- Transport, installation, start-up and training.
Complete line built in 2017
In september 2017 we have finished the manufacturing of a very special twin head UHT-line for one of our clients. An automatic processed cheese blending, inline cooking and UHT line for 1.500kg/h. With this line it is possible to mix and cook processed cheese for IWS or triangle packed hotfill processed cheese.
The continuous cooking equipment is equipped with an separate grinder/mincer for cheese blocks, a Ribbon blender of 2.000kg capacity per batch and a buffer tank on load cells with 2 augers pushing the product into a special spin type pump. After this pump an inline cooker heats the mix of cheese, fat, melting salt and flavors to 80°C by injecting steam. The melded product is send to a twin head UHT unit where it is heated to 142°C for 10 seconds.
This unique UHT has 2 independent injector heads, holding tubes and counter pressure valves, to be able to sterilize the cheese in one head while the other head is being cleaned. The 2 lines are separated by mixproof valves. After the holding tube the cheese is cooled down by vacuum in a flash vat. The flashvat has 2 pressure transmitters to control the level and is polished for easy cleaning. A balance for warm water and flowtransmitters are installed to force out water and product fully automatic with a minimum on losses. Optional the unit can be equipped with a 3 speed option 50-75-100% and different holding tubes. Because of easy cleaning and full automatic switch between the heads minimum labor is needed and long run times are possible.
The pumps are all equipped with variable drive for a flow of 18.000ltr/h during cleaning and 1.500 in production with 1 ‘spin’ type pump. The system has mix proof valves to switch between injector heads without dismantling or swingbend panels. Flowtransmitters to automatic replace product by water and back with minimum losses. Flowtransmitters are used to calculate the volumes and control pneumatic valves to automatic replace product by water and back with minimum losses.
After the UHT, 2 Creaming tanks with a transfer/cip pump are installed, with sampling points and double filters.
A separate 4 tank full automatic CIP unit is supplied with a maximum flow of 25.000ltr/h.
The unit has local touch screen control panels (Siemens) and a remote PC with a scada system for registration (in Siemens wincc) of signals like temperatures, times, flows during cleaning and production. Remote log in through internet is possible.
