Product Tips (cont.)

Some cappuccino or latté mixes contain dairy products which can spoil if not refrigerated. If the freezer is to be turned off at night these products must be removed from the freezer.

Contact your local health department regarding its regulations for proper mix handling and storage.

Carburetor Assembly

Your new freezer uses a metering device, known as a carburetor, to feed the proper ratio of mix and air into the freez- ing cylinder (and to prevent frozen product from rinsing out of the freezing cylinder).

The carburetor, or carb tube, is a tube with a hole, or series of holes, bored through the side. It is located in the hop- per and fits in the hole that leads to the freezing cylinder. Air flows into the freezing cylinder through the top of the

tube and mix flows in through a smaller hole in the side

 

 

 

of the carb tube. The size of the mix inlet hole can be

 

 

 

balanced with the viscosity (thickness) of the liquid mix

 

 

 

and product draw rate, in such a way that the proper

 

 

 

amount of mix is fed into the freezer cylinder to blend

 

 

 

with air at just the right ratio. Mix viscosity varies by mix

 

 

 

type, mix temperature and mix age. Different serving

 

 

 

rates also demand different feed rates. For many prod-

 

 

 

ucts, the proper mix to air ratio is generally accepted

volume of one and one-half gallons of frozen product. This

 

additional volume is the overrun in the product. Crathco offers three versions of carb tubes (see Figure A). Depending on the product being served and overrun requirements there is a standard tube for most slush or cocktail products, a low overrun carb tube that allows all air trapped in the freezing cylinder to escape and a smoothie/shake carb tube.

This carb tube has an outer sleeve that can be rotated to line up with different hole sizes providing various levels of overrun. Most applications only require the standard carb tube.

Mix Considerations - General

Freezing characteristics are affected by the amount of sweeteners and solids in the mix. The amount of sweeteners and solids is called BRIX. BRIX can be measured with an instrument called a refractometer. A BRIX reading of between 11 and 14 will provide optimum freezer operation. Mixes with this BRIX level will freeze down to a smooth, uniform consistency. Mixes with too high a BRIX level will take longer to freeze down and will yield a soft, wet frozen product. Mixes with too low a BRIX level will have larger ice crystals and will have a tendency to dispense slowly. Alcohol content also affects product freezing characteristics. High alcohol content may prevent the freezer from serving product at proper thickness.

Note: Always take BRIX measurement using mix that has been thoroughly blended, before it is frozen. Always allow frozen mix to thaw thoroughly before taking a reading.

For maximum output capacity, always pre-chill mix before adding it to the freezer. Pre-chilled mix gives the freezer a head start on the freezing process and will speed both initial freeze down and recovery time. It is normal for output capacity to decrease when warm mix is added, or when the freezer is operated in a warm area.
