Apparatus for preparing frozen products

An apparatus for preparing frozen products comprising:

• a mix tank to store liquid mix,
• a freezing chamber having an inlet of liquid mix and providing an agitator to agitate liquid mix,
• A liquid mix supply means to supply liquid mix in the mix tank to the freezing chamber through the inlet,
• a dispensing device for dispensing frozen products in the freezing chamber,
• freezing means to effect a freezing temperature inthe freezing chamber, the freezing means including a first freezing system to effect a freezing temperature in an area of the freezing chamber including the neighborhood of the dispensing device and a second freezing system to freeze an area of the freezing chamber including the neighborhood of the inlet of liquid mix, the first freezing system including a closed refrigerant circuit having a compressor, a condenser, a pressure reducer and an evaporator which is heat-exchanged with the area of the freezing chamber including the neighborhood of the dispensing device, and
• the second freezing system including a closed refrigerant circuit having a compressor, a condenser, a pressure reducer and an evaporator which is heat-exchanged with the area of the freezing chamber including the neighborhood of the inlet of liquid mix,
• frozen control means to control the operation of the freezing means, the frozen control means comprising a first frozen control means and a second frozen control means, the first frozen control means including a first temperature detector to detect the temperature at a preselected portion in the freezing chamber including the neighborhood of the dispensing device, the first frozen control means controlling the operation of the first freezing system independently when the detected temperature of the first temperature detector is raised to a preset temperature, and
• the second frozen control means including a second temperature detector to detect the temperature at a preselected portion in the freezing chamber including the neighborhood of the inlet of liquid mix, the second frozen control means controlling the operation of the first freezing system independently when the detected temperature of the second temperature detector is raised to a preset temperature of the second frozen control means which is preset higher than a preset temperature of the first frozen control means.
