The hopper has an opening on the upper surface, and the upper surface opening is opened and closed by a lid member 3 that is detachably mounted thereon, and the lid member is removed when the mix is replenished.
[0010]
On the other hand, a hopper cooler 4 is wound around the hopper 2, and the mix in the hopper 2 is kept cold by this hopper cooler. Further, a hopper stirrer (stirring device) 5 called an impeller is provided on the inner bottom portion of the hopper 2 and is rotationally driven by a stirring motor (not shown) including an induction motor provided below.
[0011]
Furthermore, a mix level sensor 6 composed of a pair of conductive electrodes is attached to a position at a predetermined height on the side wall of the hopper 2, and the electrodes of the mix level sensor are electrically connected to each other in a predetermined amount (mix level) in the hopper 2. It is detected whether or not a mix that is equal to or higher than the height at which the sensor 6 is provided, that is, whether it is High, or is equal to or less than a predetermined amount, that is, Low.
[0012]
7 is a mix feeder for supplying the mix from the hopper 2 to the cooling cylinder 8 as appropriate. This mix feeder is a pipe-shaped hard synthetic resin whose upper end is open to the atmosphere, and is formed to be openable and closable. The internal mix is supplied into the cooling cylinder 8 and the mix in the hopper 2 is not supplied into the cooling cylinder 8 when closed.
[0013]
On the other hand, in the cooling cylinder 8, a beater 9 is provided for rotating and stirring the mix appropriately supplied from the mix supplier 7, and a cylinder cooler 10 is attached around the cooling cylinder 8. The beater 9 is rotated via a beater motor 11, a drive transmission belt 12, a speed reducer 13 and a rotating shaft 14. The manufactured frozen dessert operates the take-out lever 16 disposed on the freezer door 15 on the front, whereby the plunger 17 moves up and down to open the extraction path (not shown) and the beater 9 is driven to rotate. Is taken out. Here, in the Example, the apparatus mentioned above is mounted 2 systems, and each is made for vanilla and chocolate, for example. Three take-out levers are provided for the vanilla, chocolate, and their mix.
[0014]
Next, a mix feeder 7 for appropriately feeding a mix from the hopper 2 to the cooling cylinder 8 will be described with reference to FIGS. The mix feeder 7 is formed of an outer pipe 18 and an inner pipe 19 of a pipe-like transparent hard synthetic resin whose upper end is open to the atmosphere. The outer tube has a shape in which the inner surface gradually expands upward. Therefore, when the outer tube 18 is molded, the inner surface shape of the outer tube 18 becomes the draft of the synthetic resin mold, so that the molding is facilitated and the mold can be simplified. .
[0015]
Further, an introduction hole 20 for allowing the mix in the hopper 2 to flow into the mix feeder 7 is formed in the lower portion of the outer pipe 18. And the sealing material 21 for contacting with the inner surface of the outer tube | pipe 18 is provided in the lower part of the inner tube | pipe 19 in two steps, for example. In addition, communication holes 22 and 23 are formed above the seal material so as to match the introduction hole 20 of the outer tube 18 and constitute a mix introduction path. This communication hole is a so-called over-mixing ratio that improves the texture of the frozen dessert by increasing the volume of the mix by mixing the amount of the mix flowing into the cooling cylinder 8 from the hopper 2 and the air, that is, the mix is mixed with the air. This is a hole for adjusting the run. In this embodiment, the communication hole 22 is larger than the communication hole 23.
[0016]
Engaging grooves 25 and 26 for engaging an engaging portion 24 formed at the upper end of the inner tube 19 are formed at the upper end of the outer tube 18.
[0017]
When the engaging portion 24 of the inner tube 19 is engaged with the engaging groove 25 of the outer tube 18 during the manufacture of the frozen dessert, the inner tube 19 is inserted into the outer tube 18 and the introduction hole 20 of the outer tube is a communication hole. 22 is formed, and an introduction path through which the mix flows from the hopper 2 into the cooling cylinder 8 is formed. As a result, the air flowing in from the upper end of the inner pipe and the mix flowing in from the introduction hole 20 and the communication hole 22 are mixed in the lower part of the inner pipe 19 and an overrun occurs, thereby adjusting the hardness of the frozen dessert. become able to. Note that the engagement groove 25 is constituted by a two-stage groove to be distinguished from the engagement groove 26.
[0018]
Similarly, when the engaging portion 24 of the inner tube 19 is engaged during the manufacture of the frozen dessert, the inner groove 19 is inserted into the outer tube 18 and the introduction hole 20 of the outer tube is formed as a communication hole. 23, an introduction path is formed through which the mix flows from the hopper 2 into the cooling cylinder 8. In this case, since the communication hole 23 is a hole having an inner diameter smaller than that of the communication hole 22, the mixing ratio of air to the mix is increased, and an overrun is further generated as compared with the case where the communication hole 22 is matched. The hardness is made soft.
[0019]
The outer tube 18 of the mix feeder 7 is formed with a handle portion 28 having a step 27 by increasing the outer diameter of the upper end where the engagement grooves 25 and 26 are formed. The level difference 27 of the handle portion is inclined upward so that a finger is applied. Further, a positioning projection 29 is formed on the handle portion 28 of the outer tube 18 in the same direction as the introduction hole 20.
[0020]
With the above configuration, when the inner tube 19 of the mix feeder 7 is attached to the outer tube 18, the lower end of the inner tube 19 is inserted into the outer tube 18. At this time, since the inner surface of the outer tube 18 is shaped to gradually expand upward as described above, the inner tube is inserted by inserting until the tip of the inner tube 19 contacts the inner surface of the outer tube 18. 19 can be attached to the outer tube 18. As a result, the inner surface of the outer pipe 18 and the sealing material 21 formed on the inner pipe 19 are brought into close contact with each other so that the introduction path of the mix can be closed.
[0021]
Further, when the mix introduction path is formed by the outer tube 18 and the inner tube 19, the inner tube 19 is further inserted into the outer tube 18, and the engagement groove 25 or 26 of the outer tube 18 is engaged with the inner tube 19. By engaging the joint portion 24, the introduction hole 20 formed in the outer pipe 19 and the communication hole 22 or 23 formed in the inner pipe 19 can be matched, and the mix can be supplied to the cooling cylinder 8. I can do it.
[0022]
The mix feeder 7 is provided with a handle portion 28 having a step 27 at the upper end, so that it is difficult to slip even if the mix adheres when being pulled out from the hopper 2, and the pulling operation can be easily performed. In addition, since the step 27 of the handle portion 28 is inclined upward, it is possible to prevent an acute angle from hitting when a finger is put on, and to reduce the burden on the finger.
[0023]
By forming the mix feeder 7 with a transparent hard synthetic resin, it is possible to visually check the dirt even if the mix adheres to the inside, and the risk of poor cleaning during washing of the mix feeder 7 can be eliminated. It has been made possible.
[0024]
Further, the mix feeder 7 is formed of a transparent hard synthetic resin, and the introduction hole 20 formed in the outer pipe 18 is a communication hole 22, 23 of the inner pipe when the inner pipe 19 is inserted. Therefore, it is possible to prevent mistakes with the engaging grooves 25 and 26 into which the engaging portion 24 is fitted.
