Abstract
An extrusion device for an ice cream or yogurt machine includes an air delivery channel and a material delivery channel individually extended along a tube body, wherein the air delivery channel and the material delivery channel are arranged for concurrently delivering a flow of air and a flow of raw material. A diameter size of the air delivery channel is smaller than that of the material delivery to match with viscosities of air and raw material.
Claims21
An extrusion device for an ice cream or yogurt machine having a frozen cavity, comprising:
- a tube body, which is arranged for being installed into the frozen cavity, wherein the tube body, which has a straight tube configuration, has a first body portion, a second body portion coaxially extended from said first body portion, a first end defined at said first body portion, and an opposed second end defined at said second body portion, wherein a length of said first body portion is longer than a length of said second body portion;
- an air delivery channel extended along said tube body from said first body portion to said second body portion, wherein said air delivery channel has an air outlet and an air inlet adapted for connecting to an air source for introducing a flow of air from said air inlet to said air outlet through said air delivery channel;
- and a material delivery channel extended along said tube body at said second body portion, wherein said material delivery channel has a material outlet and a material inlet adapted for connecting to a material source for introducing a flow of raw material from said material inlet to said material outlet through said material delivery channel, wherein a diameter size of said air delivery channel is smaller than that of said material delivery channel, wherein said material delivery channel is individual and spaced apart from said air delivery channel for enabling the air and raw material being introduced into the frozen cavity at the same time.
An extrusion device for an ice cream or yogurt machine having a frozen cavity, comprising:
- a tube body having a straight tube configuration for being inserted into the frozen cavity;
- and
- a delivery arrangement which comprises two individual delivery channels formed within said tube body for concurrently delivering a flow of air and a flow of raw material respectively, wherein one of said delivery channels having a smaller diameter size is configured as an air delivery channel while another said delivery channel having a larger diameter size is configured as a material delivery channel.
A method of manufacturing an extrusion device for an ice cream or yogurt machine having a frozen cavity, comprising the steps of:
- (a) forming a tube body to have a straight tube configuration to be inserted into the frozen cavity;
- (b) forming an air delivery channel along said tube body for delivering a flow of air;
- and
- (c) forming a material delivery channel along said tube body for delivering a flow of raw material, wherein a diameter size of said air delivery channel is smaller than that of said material delivery channel, wherein said material delivery channel is individual and spaced apart from said air delivery channel to enable the air and raw material being introduced into the frozen cavity at the same time.
