DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to ice cream making machines, and more particularly to a portable machine for making ice cream or other frozen comestibles from liquid ingredients.
Ice cream making machines are well known and various models are available on the market. Many of the large units include internal compressors with coils through which a cooling liquid passes in order to provide adequate reduced temperatures for the formation of the ice cream. Some available machines are associated with into freezers and utilize the flow through the freezing coils of the freezer for the reduced temperatures required for making the ice cream. One such machine is described in U.S. Pat. No. 4,632,566.
Most types of ice cream making machines require special ingredients in order to form the ice cream. Such ingredients typically include a cream substance, sugar,, starches, and various other products either mixed together or purchased as a premix, and utilized in the formation of the ice cream.
One of the considerations of a useful ice cream making machine is the time required for producing the output. Many of the existing machines take a considerable amount of time from when the ingredients are inserted until the final product is produced. These machines are not desirable because of such lag in time. Another criteria for a good machine is the quality of the product. The final product must be one that is of good consistency, that is smooth, well blended, without the presence of lumpy or unwanted particles, and tasty. This aspect, namely the quality of the product, is the most important criteria for a successful ice cream making machine.
While such ice cream making machines are readily available and described in various prior art references, nevertheless none of the available device have provided an adequate quality product at sufficiently fast rate with continuous reproducable consistent results and which is easy to use, simply to assemble, and easy to clean and maintain.
It should be appreciated, that although ice cream making machines are described, the term "ice cream" is meant in a generic sense and refers to various types of frozen comestibles including ices, ice creams, ice milks, and the like.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide an improved ice cream making machine which quickly produces a high quality product.
Yet another object of the present invention is to provide an ice cream making machine which is easy to utilize, fast in operation, easy to clean, and produces a high quality output.
Yet a further object of the present invention is to provide an ice cream making machine which produces an output from simple liquid ingredients such as fruit juices, chocolate milk, and the like.
Yet a further object of the present invention is to provide an ice cream making machine having a removable cannister which can be stored in a freezer and placed into the machine when being used.
Still a further object of the present invention is to provide a portable ice cream making machine which includes a drive shaft having multiple uses including driving a rotor for mixing the liquid ingredients, feeding the liquid ingredients to the rotor, locking the rotor in place, and facilitating removability of the parts for easy cleaning and maintenance.
A further object of the present invention is to provide an ice cream making machine where the liquid ingredient is center fed to a rotor whereby the liquid ingredient is radially dispensed outwardly toward the blades of the rotor.
Another object of the present invention is to provide and ice cream making machine which fluffs the liquid ingredients to make a high quality product.
Briefly, in accordance with the present invention, there is provided a machine for making ice cream and the like, which includes a receptacle for receiving the liquid ingredients to be used for making the ice cream. A mixing chamber is provided which includes an egress from which the ice cream exits. A cooling chamber surrounds the mixing cha
