Application
Freezing, mixing and whipping of air into ice cream, scraped surface freezing of other products
Operating principle
The ice cream mix is supplied to the freezer direct or via a mix balancing tank placed on top of the freezer cabinet. The ice creammix is led to the mix pump which is fitted with an adjustable air intake valve, and pumps a mixture of mix and air into the freezing cylinder, During the passage through the freezing, cylinder the air is whipping into the ice cream by a dasher. Freezing of ice cream is carried out by means of liquid
Freon, evaporating in the cooling jacket around the freezing cylinder, the stainless steel blade of the dasher scrape in the Frozen ice cream, from the inside wall of the freezing cylinder and the pump pressure, forwards the ice cream via the adjustable, constant pressure valve to a filling machine.
Standard design
All parts of the freezer are produced from high quality materials and engineer to meet strict standard of hygiene, reliability and durability All parts of the freezer in contact with mix and ice cream are manufactured from stainless materials
The dasher equipped with scraper blades and a beater is made of stainless steel
The freezer cabinet
Is a self- supporting construction with bottom plate, front panel back panel and top plate in stainless steel plate welded and bolted together. The two stainless steel side plate are detachable.
Pressure regulating valve
A constant pressure regulating valve is installed at the ice cream outlet of the freezing cylinder. The valve ensures the constant pressure in the freezing cylinder
The mix air pump
Is located on the front of the freezer, making it very easy to clean and maintain.
The refrigeration system
Is equipped with a built-in semi hermetic Freon compressor, The operating conditions of the refrigeration system can be monitored on a manometer on the front of the freezer cabinet, Defrosting of the freezing cylinder and adjustment of the ice cream viscosity can take place by means of a Freon hot gas valve, operated from the front of the freezer cabinet, the Freon condenser is water side of the condenser is easy to clean and maintain.
The freezing cylinder
With its hard chromium-plated and mirror finished inner surface, provides efficient freezing of the Mixing balancing tank
With a float-operated valve which ensures a constant mix supply, pressure to the mix pump
. Start/ stop of the refrigeration system
. Start/stop of the hot gas system
. Electronic control of the ice cream capacity
. Electronic display of the ice cream viscosity
Cleaning
Of the freezer can be carried out by connection to a central CIP system to ensure maximum hygiene at minimum operational cost. The freezer is equipped with camp type pipe connections.
Operation of the freezer
Start –up of the freezer
Is very easy, after connection to the power and water the freezer is ready to operate
The control panel
In stainless steel execution, is located on top of the freezer cabinet, and includes the following operational features.
Start/ stop of the mix pump
Start/ stop of the dasher
Nominal output
180 - 300 liters per hour
