[0010]
Reference numeral 1 denotes a frozen dessert manufacturing apparatus main body, which has two cylinders so that two types of soft creams, for example, vanilla soft cream and chocolate soft cream can be manufactured. And as a soft cream which can be extracted, three kinds of vanilla soft cream, chocolate soft cream, and mixed soft cream obtained by mixing these can be sold. In addition to these three types of soft cream, a frozen dessert called a shake can be sold by changing the set temperature. The soft cream is manufactured in a temperature range of about −8 ° C., and the shake is manufactured in a temperature range of about −3 ° C.
[0011]
In FIG. 1, reference numeral 2 denotes a hopper for storing a raw material of frozen confectionery (soft cream or shake), a so-called mix, having a hopper cover 3 that is removed when the mix is replenished, and a hopper cooling coil 4 wound around the hopper 2. The mix is kept cool. Further, the impeller 5 provided on the inner bottom portion is also rotationally driven when a predetermined amount or more of the mix is put in the hopper 2 and is sterilized by heating with the refrigerant gas that flows in the hopper cooling coil 4 opposite to the cooling time, that is, hot gas. The 7 is a capacitance type mix level sensor for detecting whether or not the hopper 2 has a predetermined amount or more of the mix. If the mix is insufficient and the amount is less than the predetermined amount, it becomes non-conductive and hot so as not to perform the heat sterilization process. The gas flow is stopped or the impeller 5 is not rotated.
[0012]
A mix feeder 9 extending upward is provided from the bottom surface of the hopper 2. Reference numeral 8 denotes a cooling cylinder for producing a frozen dessert by rotating and stirring the mix appropriately supplied from the hopper 2 by the mix feeder 9 using the beater 10, and an evaporator 11 is arranged around the cooling cylinder. The beater 10 is rotated via a beater motor 12, a drive transmission belt 13, a speed reducer, and a rotating shaft 16. The manufactured frozen dessert is taken out by operating the take-out lever 15 disposed on the freezer door 14 so that the plunger moves up and down to open the extraction path. Here, in this apparatus, three take-out levers are provided.
[0013]
That is, the left extraction lever 15A is for vanilla, the right extraction lever 15B is for chocolate, and the center extraction lever 15C is for mixing vanilla and chocolate. For this purpose, another cooling cylinder 8 is provided. The cooling cylinder 8 is used for manufacturing vanilla soft cream or shake, and the cooling cylinder 8 is used for manufacturing chocolate soft cream or shake. In addition, at the time of taking out the frozen dessert, each beater 10 rotates and fulfills the action of delivering the frozen dessert.
[0014]
Next, a refrigeration apparatus for cooling the hopper 2 and the cooling cylinder 8 will be described. Reference numeral 18 denotes a compressor, and 20 a water-cooled condenser, which condenses and liquefies the flowing high-temperature and high-pressure refrigerant gas into a liquefied refrigerant. Then, it flows into the evaporator 11 and evaporates to cool the cooling cylinder 8. Alternatively, the liquefied refrigerant liquefied by the water-cooled condenser 20 flows into the hopper cooling coil 4 and similarly evaporates and cools the hopper 2 and exits. Reference numeral 19 denotes a cooling fan for cooling the compressor 18.
[0015]
By the way, in this cooling operation, it is necessary to maintain the temperature for obtaining a high-quality frozen dessert within a predetermined set temperature range (cooling cylinder: about −3 ° C. to −8 ° C., hopper: 5 ° C. to 10 ° C.). Therefore, cooling is maintained by a temperature sensor.
The gist of the mix feeder 9 of the present invention will be described below with reference to FIGS. An insertion tube 21 is provided at the rear of the cooling cylinder 8, and a mix supply chamber 22 is formed in the cooling cylinder 8 so as to face the insertion tube 21. Further, the insertion tube 21 communicates the hopper 2 and the mix supply chamber 22 of the cooling cylinder 8, and the upper surface opening of the insertion tube 21 is open to the bottom surface of the hopper 2. Further, a detachable lower tube 23 is inserted into the insertion tube 21. The lower tube 23 is provided with a short lower tube 23A shown in FIG. 6 and a long lower tube 23B shown in FIG. The lower part of the inner surface of the lower cylinder 23 is inclined outward, so that the mix can smoothly flow into the cooling cylinder 8.
[0016]
FIG. 8 shows a state in which the lower tube 23 is inserted into the insertion tube 21. The lower tube 23 is formed with a groove 24 for providing a rubber O-ring (not shown). The mix is not leaking in between. Further, a flange 26 is provided at the upper end of the lower cylinder 23 so as to cover the bottom opening edge of the hopper 2. When the lower cylinder 23 is inserted into the insertion tube 21, the flange 26 of the lower cylinder 23 lowers the lower cylinder 23. The cylinder 23 itself is held.
[0017]
FIG. 9 shows a state where the short lower tube 23A is inserted into the insertion tube 21, and FIG. 10 shows a state where the long lower tube 23B is inserted into the insertion tube 21. The mix amount at this time is filled as shown by a two-dot chain line in the figure. For this reason, it is possible to adjust the overrun in the cooling cylinder 8 by adjusting the protruding amount of the lower cylinder 23 in the cooling cylinder 8.
[0018]
That is, when the amount of protrusion of the lower cylinder 23B into the cooling cylinder 8 is large, naturally the amount of mix supplied into the cooling cylinder 8 is small (FIG. 10) and the amount of air inside is large, so the amount of air contained is large. A light-tasting frozen dessert can be produced.
In addition, when the amount of projection of the lower cylinder 23A into the cooling cylinder 8 is small, the amount of mix supplied into the cooling cylinder 8 is increased (FIG. 9), so that a frozen confection with a small amount of air and a firm texture is produced. can do.
[0019]
An upper cylinder 25 is detachably attached to the lower cylinder 23, and the upper cylinder 25 protrudes above the mix stored in the hopper 2. Further, a notch 27 is partially formed in the upper end edge of the upper cylinder 25, and an outer cylinder hole 28 for distributing the mix in the hopper 2 is formed in the lower part. The upper cylinder 25 and the lower cylinder 23 form an outer cylinder 29.
[0020]
Further, inside the outer cylinder 29, an inner cylinder 32 having a fin piece 30 fitted to the notch 27 in the upper part and having an inner cylinder hole 31 formed in the lower part is inserted. By positioning the fin piece 30 in a notch 27 formed in the upper cylinder 25, the inner cylinder 32 can be moved downward. In this state, as shown in FIGS. 13 and 14, the outer cylinder hole 28 and the inner cylinder hole 31 face each other. Therefore, the mix in the hopper 2 can be supplied to the cooling cylinder 8 by positioning the fin piece 30 in the notch 27.
[0021]
The inner cylinder 32 is formed with two grooves 33 below the lower inner cylinder hole 31, and this groove 33 is in a state where the inner cylinder 32 is positioned at the upper end edge of the upper cylinder 25, that is, the inner cylinder In the state where 32 is located above, it is located above and below the outer cylinder hole 28 of the upper cylinder 25. The groove 33 is provided with a rubber O-ring (not shown). For this reason, it is possible to prevent the mix from leaking between the outer cylinder 29 and the inner cylinder 32 in the state in which the mix supply is stopped (FIGS. 11 and 12) by pulling the inner cylinder 32 upward.
[0022]
The operation of the frozen dessert manufacturing apparatus 1 having the above configuration and including the mix feeder 9 of the present invention will be described.
First, at the time of pull-down, the frozen dessert manufactured with an appropriate overrun the previous day is sterilized by heating and cooled. Simultaneously with this cooling, the beater 10 rotates. However, the inner cylinder 32 of the mix feeder 9 is pulled upward, and the positions of the inner cylinder hole 31 and the outer cylinder hole 28 of the outer cylinder 29 are shifted. Is prevented from flowing into the cooling cylinder 8. For this reason, the frozen dessert in the cooling cylinder 8 can be restored with the optimum overrun manufactured on the previous day.
[0023]
Further, when manufacturing the frozen dessert, the mix in the hopper 2 is allowed to flow into the cooling cylinder 8, the overrun of the dessert desired to be manufactured is adjusted by the lower cylinder 23, and the mix is stirred and cooled to obtain the desired frozen dessert. Manufacturing. For the adjustment of the lower cylinder 23, two types of lower cylinders 23A and 23B are prepared, and by using these two types of lower cylinders 23, overrun can be adjusted. That is, since the length of the lower cylinder 23 protruding into the cooling cylinder 8 is different, the amount of mix flowing into the cooling cylinder 8 can be adjusted, so that the mixing ratio of the mix and air in the cooling cylinder 8 This can be used to adjust the overrun.
[0024]

By moving the cylinder 32 in the vertical direction, the inner cylinder hole 31 that communicates with the outer cylinder hole 28 and the outer cylinder hole 28 and the inner cylinder hole 31 that meet each other communicate with the cavity of the inner cylinder 32. cold A mix supply apparatus capable introduce the mix into the cylinder 8.
[0028]
For this reason, the inner cylinder 32 is moved in the vertical direction with respect to the outer cylinder 29 (the upper cylinder 25 and the lower cylinder 23), and the hopper 2 mixes only when the outer cylinder hole 28 and the inner cylinder hole 31 are aligned. It can flow into the cooling cylinder 8. Therefore, it can be achieved only by shifting the positions of the outer cylinder hole 28 and the inner cylinder hole 31.
[0029]
【The invention's effect】
