Frozen product machine
A frozen product machine that solves problems associated with conventional home ice cream and frozen product machines by prevents loss of product in the chamber and decreases freezing time for a liquid product. A cooling chamber is cooled by a cooling element that provides variable cooling temperatures throughout the cooling chamber. A temperature gradient, progressing from lower temperatures at the bottom of the chamber, or the outlet, to higher at the top of the chamber, or inlet, create a more efficient means of cooling a frozen product. An auger, that may be shaped to match the shape of the cooling chamber may include slots that allow for controlled flow of frozen product through the chamber to promote efficient cooling. Hinged fins may rotate from open to closed within the slot to further enhance flow of frozen product through the frozen product machine.
1. An apparatus, comprising:
a chamber for receiving a material;
an auger adapted to fit within the chamber;
the auger connected to a motor for rotating the auger;
wherein the motor has a mixing motor setting and a dispensing motor setting;
wherein the mixing motor setting causes the auger to rotate in a first direction;
wherein the dispensing motor setting causes the auger to rotate in a second direction;
wherein the first direction is substantially opposite to the second direction;
wherein the auger includes at least one slot and at least one fin;
wherein the at least one fin has a substantially open position to promote a flow of the material through the at least one slot, and a substantially closed position to inhibit a flow of the material through the at least one slot; and
wherein the at least one fin is in the substantially open position during mixing and in the substantially closed position during dispensing of a product.
2. The apparatus of claim 1 , wherein the chamber has an inlet, an outlet, and a nozzle for dispensing the product.
3. The apparatus of claim 1 , wherein the auger and the chamber are supported by a housing.
4. The apparatus of claim 1 , wherein the at least one fin is attached adjacent to the at least one slot.
5. The apparatus of claim 1 , wherein the motor is reversible.
6. The apparatus of claim 1 , wherein the chamber is conical and vertically oriented.
7. The apparatus of claim 1 , wherein the chamber has a temperature sensor coupled to the motor such that a direction of the motor is reversed when a pre-set temperature is reached, causing the auger to change from the first direction to the second direction.
8. The apparatus of claim 1 , wherein the at least one fin is an at least one hinged fin.
9. The apparatus of claim 1 , further comprising a cooling element adapted to cool a cooling chamber.
10. The apparatus of claim 9 , wherein the cooling element includes a compressor and motor unit; and
wherein the compressor and motor unit includes an evaporator coil for cooling the cooling chamber.
11. The apparatus of claim 10 , wherein the evaporator coil has an evaporator coil density that is greater at a designated portion of the cooling chamber.
12. A method, comprising:
adding a material into a chamber;
mixing the material in the chamber by rotating an auger in a first direction,
wherein the auger has at least one slot and at least one fin;
wherein the at least one fin is in a substantially open position during mixing;
dispensing the material by rotating the auger in a second direction, wherein the second direction is substantially opposite to the first direction;
changing a position of the at least one fin from the substantially open position to a substantially closed position during dispensing to inhibit a flow of the material through the at least one slot in order to promote dispensing.
13. The method of claim 12 , wherein the chamber has an inlet, an outlet and a nozzle.
14. The method of claim 12 , wherein the at least one fin is attached adjacent to the at least one slot.
15. The method of claim 12 , further comprising changing a setting on a motor to rotate the auger in the second direction.
16. The method of claim 12 , further comprising a cooling element for cooling the material in the chamber.
17. The method of claim 16 , wherein the cooling element includes a compressor and motor unit; and
wherein the compressor and motor unit includes an evaporator coil for cooling the chamber.
18. The method of claim 17 , wherein the evaporator coil has an evaporator coil density that is greater at a designated portion of the cooling chamber.
19. A method, comprising:
adding a material into a chamber,
wherein the chamber includes an auger having at least one slot and at least one fin;
substantially opening the at least one slot and mixing the material in the chamber by rotating an auger in a first direction; and
substantially closing the at least one slot and dispensing the material by rotating the auger in a second direction.
