Base/additive product feeding unit for a machine for the production and/or distribution of an ice cream product and machine comprising said unit
A base/additive product feeding unit for a machine for the production and/or distribution of ice cream, or other ice cream product, comprises a plurality of storage tanks for delivering predetermined quantities of base/additive products used to prepare ice cream in a batch freezing chamber provided with a stirrer and heat treatment means. The connection between the storage tanks and the batch freezing chamber is accomplished by an intake having a plurality of side inputs connected to respective storage tanks and an additional input made in a cover of the intake and connected to a further storage tank in such a way as to allow at least two storage tanks to be superposed on each other.
1. A machine for single-dose production and distribution of an ice-cream product, comprising:
a base/additive product feeding unit, comprising:
a plurality of storage tanks containing respective base/additive products, arranged side by side and configured to contain and deliver predetermined quantities of base/additive products the plurality of storage tanks including a first group and a second group;
a collecting unit for receiving the predetermined quantities of the base/additive products necessary to produce at least one dose of an ice cream product;
the collecting unit comprising a first intake and a second intake, the first intake having two side inputs respectively connected to two of the storage tanks of the first group to receive the predetermined quantities of base/additive products from the two of the storage tanks of the first group,
the second group including a further storage tank being situated above one of the two of the storage tanks of the first group,
the second intake including a removable cover having an opening connected by a conduit to the further storage tank to provide an additional input to the collecting unit from the further storage tank to receive the predetermined quantities of base/additive products from the further storage tank,
at least one batch freezing chamber, including a stirrer and heat treatment system, operatively connected to the collecting unit for receiving the predetermined quantities of the base/additive products necessary to produce at least one dose of an ice cream product.
2. The machine according to claim 1 , further comprising a release element, associated with the collecting unit, that is movable between a closing position and an opening position to permit the release of product contained within the collecting unit.
3. The machine according to claim 2 , wherein the release element includes a valve.
4. The machine according to claim 1 , further comprising an air duct and a base liquid duct for supplying, respectively, air and base liquid into the intakes.
5. The machine according to claim 4 , comprising a first valve for closing the air duct and a second valve for closing the base liquid duct.
6. The machine according to claim 1 , and further comprising a plurality of motorized augers connected to the plurality of storage tanks, respectively for delivering the predetermined quantities of base/additive products.
7. The machine according to claim 1 , wherein the cover includes a partition extending into the second intake.
8. The machine according to claim 4 , wherein the collecting unit further includes a hopper-shaped upper portion and a mixing chamber located under the hopper-shaped upper portion.
9. The machine according to claim 4 , wherein the air duct and the base liquid duct connect into the mixing chamber.
10. The machine unit according to claim 8 , wherein the hopper-shaped upper portion has a flattened funnel shape.
11. The machine unit according to claim 1 , wherein the further storage tank and the one of the two of the storage tanks of the first group each have a height that is shorter than a height of another of the plurality of storage tanks of the first group.
12. The machine unit according to claim 1 , wherein the further storage tank and the one of the two of the storage tanks of the first group each have a height, such that when combined, the combined height is equal to a height of another of the plurality of storage tanks of the first group.
