High Output Microfilm Cooker
A high output version of the 'Microfilm' swept surface
confectionery cooker has been developed by Baker Perkins. It
enables confectionery companies to maximise the potential of the
latest generation of automated control systems.
The 'Microfilm' cooker is regarded as the industry
standard for high boiled candies, butterscotch, and milk and cream
candies. It is widely used for low boilings such as caramels,
toffees and fudges, and can also be utilised for high-solids
jellies and gums. Several hundred machines are at work throughout
the world.
The latest development features two cooker rotors on a single skid,
and is capable of maximum outputs up to 3,000 kg/hour. It can feed
the market-leading Baker Perkins series of servo-controlled
depositors, which provide higher throughputs via increased
flexibility, with rapid changeover between products, and
fine-tuning 'on the run'.
Flexible Microfilm cookers are available with a wide choice of
options, and systems are specified to match individual
requirements. The latest option is a SCADA (Supervisory
Control And Data Acquisition) software system, linked to the fully
automatic Microfilm control system that has been available for some
time.
SCADA systems cover the complete line, from pre-mixing through to
packaging, bringing benefits in process and business
efficiency. With a picture of the total process available at
a central point, key parameters such as vacuum, steam pressure,
flow rate and cook temperature can be monitored and adjusted with
benefits in consistency of product quality. Recipe management
means that all the settings for each product are stored and
recalled electronically, with real impact on speed of changeover
and start-up.
The 'Microfilm' rotor has hinged blades which sweep the inner
surface of the tube. The syrup is spread in a very thin film
and moved through the cooking tube by a combination of gravity and
the design of the hinged blades.
