Description
- The present invention relates to an automatic machine for producing and dispensing semi-liquid foodstuffs.
- In particular, without limiting the scope of the inventive concept, the present invention relates to machines for producing and dispensing ice creams, soft ice creams, yogurt ice creams, sorbets and the like.
- As is known, machines of the above-mentioned type, in particular those for producing soft ice creams referred to hereinafter by way of example, comprise a tank for containing a liquid mixture to be processed to obtain the finished product, refrigerating means associated with the tank to keep the mixture at a predetermined temperature, a horizontal whipping and freezing cylinder, to which the mixture is fed by a gear pump, and one or more dispenser taps, positioned on the whipping and freezing cylinder outfeed front wall. The gear pump pressurizes the mixture with air, making the ice cream more or less creamy.
- The dispenser taps may be operated manually, or, in the case of the automatic dispensing machines covered by this invention, they may be controlled by a control unit operating in conjunction with one or more sensors which detect the quantity of ice cream dispensed.
- As is known, said sensors consist of devices designed to detect the weight of the ice cream dispensed, for example load cells.
- In other cases there are devices equipped with volumetric sensors able to control the quantity of ice cream dispensed.
- The density of the ice cream is normally electronically controlled during production to prevent it from varying, for example with variations in the type of mixture. However, even small variations in the density can result in unacceptable variations in the volume of the ice cream dispensed.
- Moreover, it is important to consider that the types of devices described above are relatively complex, expensive and present objective difficulties in terms of manual and automatic washing.
- The aim of the present invention is to produce an automatic machine for producing and dispensing semi-liquid foodstuffs which is free of the above-mentioned disadvantage.
- Accordingly, the present invention provides an automatic machine for producing and dispensing semi-liquid foodstuffs comprising the features described in one or more of the claims herein.
- The present invention is now described, by way of example and without limiting the scope of application, with reference to the accompanying drawings, in which:

machine 1 comprises aframe 3 which substantially has the shape of a parallelepiped and supports, at the top, atank 4 for containing a basic product, in the form of a liquid mixture, to be processed to obtain theice creams 2. Associated with thetank 4 there is acircuit 5 of a refrigerating system for keeping the mixture at a predetermined temperature, in particular around 4° C. - Below the
tank 4, theframe 3 supports a horizontal whipping and freezingcylinder 6, of the known type, to which the mixture is fed by agear pump 7, positioned at thetank 4 and in communication with the tank via asuction pipe 7 a for drawing the mixture from thetank 4 and sending it by means of adelivery pipe 7 b to a whipping and freezingcylinder 6 infeed 6 a. - Inside the
cylinder 6 there is amixing blade 6 b for the product processed, which is driven in rotation about its axis by a variablespeed motor unit 6 c and can push the product towards and into adispenser tap 8 mounted on the whipping and freezingcylinder 6 outfeed front wall. Thedispenser tap 8 is checked and controlled by a control unit 9 (FIGS. 1 , 4, 5 and 6) with anactuator 10 inserted between them. - It should be noticed that the
pump 7, thesuction pipe 7 a, thedelivery pipe 7 b and thecylinder 6 as a whole form a feed andprocessing circuit 11 for the above-mentioned mixture. - As illustrated in
FIG. 1 , thecontrol unit 9 also checks and controls, using anotheractuator 12 inserted in-between, acarriage 13 for supporting aplate 14 on which a container C is stably rested, for example a glass, a cup or a cone, into which theice cream 2 is dispensed. - The
plate 14 can move between an upper station A forice cream 2 dispensing and a lower station B from which theice cream 2 is picked up by the consumer (FIG. 3 ). - The
control unit 9 receives the consent to dispense anice cream 2 from any sensor designed to serve the user, for example acoin box 15, or from a reader for keys with saved credit, and adjusts the dispensing based on the information received from asensor 16 in a predetermined position close to thetap 8. - As shown more clearly in
FIGS. 4 and 5 , thesensor 16 is designed to detect at least part of the profile of theice cream 2 dispensed and operates according to a line of action skew relative to thecentral axis 2 a according to which the height of theice cream 2 extends. Thesensor 16 may be electro-optical, in particular a photocell, ultrasonic or a thermal sensor. - According to the alternative embodiment illustrated in
FIG. 6 , thesensor 16 is of the electro-optical type, in particular a CCD type image detector, and operates according to a matrix of action substantially centered relative to thecentral axis 2 a according to which the height of theice cream 2 extends. - In the station A the
control unit 9 places and holds theplate 14 in a predetermined position relative to thesensor 16 duringice cream 2 dispensing. - During operation, after dispensing consent has been supplied by the
sensor 15 of any type at the service of the user, the user takes a container C from a stack positioned in a suitable magazine—distributor (not illustrated) in themachine 1 and places the container C on theplate 14 which is at the station A, at a predetermined height relative to thesensor 16 for the size selected. - It should be noticed that, in an automatic form, it is the
control unit 9 which serves a glass, cone or the like, in the station A by means of theplate 14 which, as indicated above, is positioned at the predetermined height relative to thesensor 16 for the size selected. - In both cases, said height is clearly greater for a small size and less for a large size.
- As illustrated in
FIG. 1 , one of the twosensors 16, for example the lower one as seen inFIG. 1 , is a container C presence sensor and allows correct container C positioning on theplate 14 to be checked. If correct container positioning is not detected, thesensor 16, by means of thecontrol unit 9, stopsproduct 2 dispensing. Obviously, the presence sensor may also consist of any sensor positioned at another point of the machine but always able to perform the checks described above. - Once
ice cream 2 dispensing has started, thesensor 16 sends an end dispensing signal when it intercepts the profile of theice cream 2 dispensed. This interception may be optical, ultrasonic or thermal, depending on the type ofsensor 16 mounted at the station A. - When
ice cream 2 dispensing has stopped, thecontrol unit 9 moves theplate 14 to the station B so that the consumer can pick up theice cream 2. - As illustrated in
