Abstract

PURPOSE:To prevent the contamination of a finished ice cream with trace of the formerly extracted syrup, by combining a refrigeration chamber, a syrup supplying line, an extractor, a valve, a solenoid valve, and a control means in a manner to exert a specific action. CONSTITUTION:A cylindrical bottom guide 110 protruded upward from the base 107 and a cylindrical top guide 111 having slightly larger diameter than the base are used to enable the lowering of loaded supporting tool 74 preventing the rolling of the tool 74. In the above weight-detecting device, the magnet 106 approaches the hall element 108 when the supporting tool 74 is lowered by the weight of the ice cream shake extracted in the cup 73. The syrup-controlling solenoid valves 20A1, 20A2, 20B1, 20B2, 20C1, 20C2, 20D1 and 20D2 and the solenoid 94 are controlled by the output voltage of the hall element 108 responding to the change in the magnetic field between the magnet 106 and the hall element 108. Especially, when the supporting tool 74 is lowered to a predetermined position, the valves are inactivated to stop the extraction operation automatically.

Description

Detailed Description of the Invention What) Industrial Field of Application The present invention is directed to the manufacture of finished frozen desserts by mixing a finished frozen dessert base in a cooling chamber and syrup fed through a syrup supply channel in a mixing chamber. It is related to the device.

(b) Prior Art In the dispenser disclosed in U.S. Pat. No. 3,460,716, the valve plug closes the boat and stops the supply of shake using a knob, and at this time, the solenoid valve is electrically closed. The configuration is such that the supply of flavor from the injector nozzle is stopped, and then the rotation of the impeller is stopped with a delay.

Such conventional configurations, by virtue of the delayed action of the impeller, are certainly a somewhat effective means of avoiding leaving a shake and syrup mixture inside the nozzle end, but they do not stop the supply of shake and syrup at the same time. Therefore, it is difficult to completely solve the problem of the flavor remaining on the tip of the injector nozzle and thus mixing the previous flavor into the next different flavor and shake mixture.

(c) Problems to be Solved by the Invention The present invention addresses the problems of the prior art, and does not leave any traces of the previous different syrup when extracting the finished frozen dessert by mixing the frozen dessert base and the selected syrup. In this way, quality is improved.

In order to solve the above-mentioned problems, the present invention provides a cooling chamber for cooling and stirring the supplied mix to form a frozen dessert base, and at least two syrup supplies through which different syrups are passed. an extractor forming a mixing chamber with a stirring member for mixing and extracting the frozen dessert base and the syrup; and a valve means for opening the passage between the cooling chamber and the mixing chamber to deliver the frozen dessert base to the mixing chamber. , a solenoid valve that opens the flow path of the syrup supply path communicating with the mixing chamber in order to feed the selected syrup to the mixing chamber, and a solenoid valve that is first deactivated based on the extraction end signal, and then the valve is activated after a delay. This frozen dessert manufacturing apparatus is provided with a control means for disabling the means and, after a delay, disabling the stirring member.

(e) Effect In the above structure, when the valve means opens the passage, the frozen dessert base finished in the cooling chamber is sent to the mixing chamber, and when the solenoid valve corresponding to the selected syrup opens, the syrup passes through the four syrup supply passages. is fed into the mixing chamber. these?
@Confectionery base and syrup are mixed by a stirring member that rotates in the mixing chamber, finished into a frozen dessert, and extracted from the extraction port. When the extraction end signal is issued, the solenoid valve first closes to stop the supply of syrup, and later, the valve means closes the passage and stops the supply of the frozen dessert base. Due to this delay trap, the syrup adhering to the tip of the syrup supply path is wiped away by the frozen confectionery base, and the stirring member that stops last acts to reduce the remaining frozen confectionery in the mixing chamber.

Next, referring to FIG. 2, a cooling system for cooling the cooling chamber (3) will be explained. The cooling system of the present invention consists of a front compressor (to), a front air-cooled condenser (3υ, not shown in detail), a double-tube front water-cooled condenser (not shown in detail) through which water passes through the inner tube, and refrigerant passes through the outer tube; Front receiver tank (to), front cooling solenoid valve (b), front expansion valve adopted as a pressure reducing device (to), front evaporation pipe (to), and front akinimulator c3D connected in an annular manner. A rear cooling system, a rear compressor (to), a rear air-cooled condenser, a rear water-cooled condenser (4G) with the same configuration as the front water-cooled condenser 02, a rear receiver tank (41), a rear cooling solenoid valve (42, as a pressure reducing device) The rear cooling system consists of a rear expansion valve (A3), a rear evaporation pipe (44), and a rear akimulator (c) connected in an annular manner.As is clear from this, the front and rear cooling systems are almost the same. It has been established with the following components.

Of these, the front evaporation pipe (to) of the front cooling system is wound around the front outer circumference of the cooling chamber (3), and the rear evaporation pipe θ of the rear cooling system is wrapped around the front outer circumference of the cooling chamber (3). By wrapping around the rear circumference, the front cooling system is able to independently cool the front part of the cooling chamber (3), and the rear s? The cooling system makes it possible to independently cool the rear part of the cooling chamber (3). In addition, in the example, the rear evaporation pipe (4) is approximately twice the winding area of the front evaporation pipe (4).
Although the winding area is set at 41, this was determined in consideration of the capabilities of the front compressor (to) and the rear compressor (to), and is not necessarily limited to the ratio of the example. Furthermore, the rear evaporation pipe (44) & is not limited to a branched configuration, but may be a single pipe wound configuration. The present invention is further not limited to the pipe winding method, but extends to those that constitute a front evaporation region and a rear evaporation region.

The system also includes a front air-cooled condenser Gυ and a front water-cooled condenser C32 as related devices of the front cooling system.

Similarly, the rear cooling system also includes a rear fan 08 and a rear water-saving valve (49) that air-cool both the rear air-cooled condenser C31 and the rear water-cooled condenser 0I. and (40
Even when water is not flowing through the inner tube, the refrigerant passing through the outer tube can be fully expected to be cooled by the fan (4G) and (481), making it extremely efficient.

Furthermore, the configuration of the front bypass pipe and the front hot gas solenoid valve 6υ added to the front cooling system, and the configuration of the rear bypass pipe 5z and the rear hot gas solenoid valve (to) added to the rear cooling system are ice-free. It works to create crystals.

So, is the front cooling system a front temperature detection element using a thermistor? The cooling operation is independently controlled based on the temperature sensing operation of 54), and the cooling operation of the rear cooling system is independently controlled based on the temperature sensing operation of the rear temperature detection element 551 using a thermistor.

3) A direct temperature detection method is used, which is placed inside the
It is also possible to adopt an indirect temperature detection method in which these are attached to the outer wall surface of the cooling chamber (3).

Next, based on FIGS. 3 and 4, the extractor (4)
The structure of is detailed. A resin cover that closes the front surface of the cooling chamber (3) (8υ has a cylindrical vertical hole (C) that opens at both ends, and extends from approximately the middle of the vertical hole @2 toward the cooling chamber (3), with the end An open cylindrical horizontal hole @9 is formed.

The opening edge of this side hole on the side of the cooling chamber (3) is screwed with a bearing plate that forms the outlet at the bottom, and the bearing plate has an umbrella-shaped shape. The shaft η extending rearward from the valve (a) is supported by a slidable trap. In addition, between the bearing plate (to) and the valve @0, there is a coil spring (
A spring (c) is arranged, and this spring (c) acts so as to press a valve port against a stepped portion usually formed in the middle of the horizontal hole (c) so that the valve (c) closes the horizontal hole. Although the valve base is mainly made of stainless steel, the part that is pressed against the step part is made of silicone material to improve sealing performance.

The mechanism that moves the valve (c) backward against magnetic force and spring force to open the horizontal hole is such that the rear end is in contact with the tip of the valve (goods), and the front end is inserted through the cover @υ and moved forward. The lower part is rotatably connected to the front part of the operating rod (to) in order to reciprocate the operating rod (A) which is slidable and protrudes from the upper part of the operating rod (A), and the cover (81) K is connected to the upper part of the operating rod (A). A solenoid device (94) and a lever (92) having a lever (92) having a pivot point (9υ) and a plunger (94A) connected to an actuation pin (93) perpendicular to the upper rear surface of the lever (921) are usually used. It is configured by a return spring (178) that returns the valve [F
]e is opened and closed automatically based on the operation of the solenoid (2), and can also be opened and closed by manually operating the lever.

In addition, the lower part of the vertical hole is used as a mixing chamber (95A) with the lower end opening as an extraction port (95A), and a stirring blade with a large number of through holes (A) is arranged in the mixing chamber (G). reactor.

This stirring blade qO is connected to the lower part of a rotating shaft that extends upward by passing through a slide bearing (particularly) that is press-fitted into the upper part of the vertical hole (c). The rotation is transmitted by connecting the end of this cable (101) to a motor (102), which will be described later. A cylindrical bearing (103) that is screwed on and protrudes inward from the cooling chamber (3) supports the front part of the stirrer σ2, and a plate-shaped heater (104) is wound around the outer surface of the front evaporation pipe (g). is prepared for sterilizing the cooling chamber (3), and this heater (104) is placed up to the rear evaporation pipe (44J).

The above-mentioned support σ4, which places the cup a3 at a position facing downward from the extraction port (95A) of the mixing chamber (to), is attached to the conical base (74A) and its outer surface at intervals of 90 degrees in the vertical direction. The support plate (74B) is formed by the four support plates (74B) arranged.
4B) is formed with a fitting stepped portion (74C) that fits into the lower surface of the cup 3 to stably support the cup.

A weight detection device (105) is configured in combination with this support (I4). The device (105) has a base (7

further comprising a coil spring (109) disposed between the magnet (106) and the base (107) to hold the magnet (106) in a predetermined position away from the Hall element (108);
When a load is applied to the support σ4), the base (10

0) is provided with a cylindrical upper guide (111) having a slightly larger diameter.

Thus, the weight detection device (105) detects the support σ→ according to the weight of the ice cream shake extracted into the cup σ9.
As the magnet (106) moves downward, the Hall element (10

) according to the output voltage of the syrup solenoid valve (20A
1), (20A2), (20B1), (20B2), (
20C1), (20C2), (20D1) and (20
D2) and the solenoid (94). In particular, when the support tool σa is lowered to a predetermined position, these are controlled to be inactive and the extraction operation is automatically terminated. More specifically, for example, when feeding the syrup in the syrup tank (2 people) to the extractor (4), one syrup solenoid valve (20A1) is opened by the extraction signal, and the support σa is opened by the first The valve closes when it passes through the position and descends to the second position. Other syrup solenoid valves (20
A2) is when the support σ4 moves from the first position to the second position when the output voltage of the Hall element (108) occurs within a preset reference time when the support σ4 descends from the stop position to the first position. The valve is opened until the support σ drops. This is because the amount of syrup will be insufficient if the support device σxun descends to the first position quickly, and the operation of the syrup solenoid valves (20A1) and (20A2) is This is effective in keeping the amount of syrup constant.

By the way, as mentioned before, the syrup supply pipes (18A), (18B), (18C) and (18D) connected to the extractor (4") and the cleaning pipe (20) are led out to the front of the main body 6e, and the As detailed in Figure 5, it communicates with the upper part of the mixing chamber.

Among these, syrup supply pipes (18A), (18B), (
180) and (18D) are composed of transparent tubes, with end nozzles (181A), (1sIB), (181C) and (181D) protruding inward of the mixing chamber (9ω), and above these a clean tube Q6. ) is located.

Next, the electric circuit configuration of the present invention will be explained with reference to FIG. (112) is the power switch, (113) is the cooling contact (
113A) and a ready contact (113B), (16) is the mix supply solenoid valve, and the pressure switch (17A) included in the pressure detection device α1 is connected in series. (i) is the syrup-out detection device, (

Thus, a switch (115) connected in series with the syrup solenoid valve (20AI), a switch (116) connected in series with the syrup solenoid valve (20A2), and a syrup solenoid valve (20A2) are connected in series.
The switch (117) is connected in series with the syrup solenoid valve (20D2), and the switch (117) is connected in series with the syrup solenoid valve (20D2).
18), the switch (119) connected in series with the stirrer motor ση, the switch (120) connected in series with the solenoid (goods), and the switch (121) connected in series with the stirring blade motor (102) are extracted. The contacts are controlled to open and close by an extraction control circuit (122) that centrally controls the operation, and this control circuit (122) is connected to a plurality of automatic return type extraction command switches (123) and (124).
, (125) and (126) start the operation. Here, extract command switch (123), (124)
, (125) and (126) are the syrup tank (2
For example, when the extraction command switch (123) is pressed, the switches (115) and (116) become operable and the extraction command is When switch (126) is pressed, switches (117) and (118) become operational. In addition, switches (119), (120) and (121
) is either extraction command switch (123) or (124)
, (125) and (126) are also simultaneously closed by the extraction control circuit (122)K. Then, the extraction control circuit (122) operates the switch (122) based on the Hall element (108) No.
All the switches whose contacts are closed among switches 115) to (121) are opened, but in the opening order, the switches whose contacts are closed among switches (115) to (118) are opened first, and then the switches whose contacts are closed are opened. The switch (120) opens with a delay, the switch (121) opens with a delay, and finally the switch (119) opens with a further delay. Note that the switch (119) is the extraction command switch (12
Regardless of the operations 3) to (126), the circuit is intermittently closed during cooling operation and under non-extraction conditions, which will be described later.

In addition, (127) is a cooling control that centrally controls the operation of the front cooling system based on the detection operation of the front temperature detection element 5 bleed mentioned above and the operation of the rear cooling system based on the detection operation of the rear temperature detection element mark. It is a circuit.

Next, the present invention will be explained in detail. The operation starts with supplying the mix to the cooling chamber (3). First, the operation switch (113) is positioned at the preparation contact (113B) and the power switch (112) is turned on. When the mix supply solenoid valve (161 opens.This opens the mix tank H.
In the first stage, it becomes approximately 6 with the gierator (6)! The pressure is regulated to 7/7, and the secondary regulator (8) further increases the pressure to about 3.5 kp/
The gas phase tube (7) suppresses the nitrogen gas whose pressure is regulated to cIl,
Furthermore, since the mix is applied through the mix suppression pipe a, this suppression causes the mix to flow through the mix supply pipe α4 from the rear inlet (14A) of the cooling chamber (3) to the cooling room (3).
K is fed. When the pressure detection device detects that a predetermined amount of mix has been supplied to the cooling chamber (3) K, the pressure switch (17A) is opened and the mix supply solenoid valve (
Close valve 1e to finish supplying the mix.

After that, the operation switch (113) is connected to the cooling contact (113).
When switching to A), cooling operation is started by the cooling control circuit (127), the mix supplied to the cooling chamber (3) is cooled, and is appropriately stirred by the stirrer @ to finish it into a shake base.

Next, the extraction operation will be explained. For example, when you press the extraction command switch (123), the switches (115) and (120)
, (121) and (119) are closed. This results in
The syrup supply solenoid valve (20A1) opens and the gas phase pipe (7
), nitrogen gas suppression (approximately 3.skg) applied to the syrup tank (2 people) via the syrup suppression pipe (11A)
/c! t), the syrup in the tank (2 persons) is transferred to the syrup supply pipe (18A), the first branch pipe (18A1'
), and is further fed from the nozzle (181A) to the mixing chamber (to) via a transparent syrup supply pipe (18A). At the same time, the solenoid (94) is energized and the plunger (94) is energized.
4A) is attracted and the actuating pin (9'3 pulls the lever (9) forward. Then, the lever (93) rotates around the fulcrum 01J and moves the actuating rod (901) backward. Due to the backward movement of the valve 2, the valve 2 is pushed backward against the spring 3, opening the side hole 2. As a result, the shake base in the cooling chamber 3 is moved by the drive motor ση.
The agitator σ is linked to the outlet (goods) to the side hole (
It is sent to the mixing room (to) through c).

In this way, the syrup and shake base that are continuously supplied to the mixing chamber (E) are stirred and mixed at an extremely high speed by the stirring blades that are linked to the drive motor (102), and are finished as an ice cream shake and extracted. Mouth (9
5A) to cup σ9.

Therefore, when the support ff4) is lowered to the first position due to the weight of the shake extracted into the cup Q3,
If the extraction speed is fast as described above, at this point, based on the signal from the Hall element (108) of the weight detection device (105), the switch (116) is closed and the syrup supply solenoid valve (20A2) is opened. Second branch pipe'' (18A2)
However, if the extraction speed is slow, the switch (116) will not close and the syrup supply solenoid valve (20A2) will not open. By applying this pressure, the syrup content in the shake is adjusted to be approximately constant. When the support σ4 descends to the second position and the weight detection device (105) detects a predetermined weight of the shake extracted into the cup σ, a signal from the Hall element (108) sends a signal to the extraction control circuit. (122) first opens the switch (115) to open the syrup supply solenoid valve (20A1).
), and if the switch (116) is closed at this time, it is simultaneously opened and the syrup supply solenoid valve (20
A2) is closed. As a result, the supply of syrup to the mixing chamber (G) is stopped. When this retreat occurs, the excitation to the solenoid is released, and the lever 02 is activated to return (178
) is returned to its normal position and the operating rod follows this! IC also returns to its forward position. As a result, the valve (A) is connected to the step (to) of the side hole (A) by the coil spring.
It is pressed by and blocks the side hole. Such syrup and shake-based electronic delayed stop operation is effective to prevent contamination of syrup from previous extraction when a different syrup is fed into the mixing chamber (G) by the next extraction. . That is, the syrup adhering to the end nozzle (181A) of the syrup supply pipe (18A) is wiped away by the frozen dessert base that is delivered even after the syrup supply is stopped. After that, the switch (121) is opened to cut off the power to the motor (102) and stop the stirring blade (supply).
This delayed stop operation of the stirring blade (97) causes the mixing chamber (
Extract the remaining shake in (e) and finally switch (1
19) Open the circuit to cut off the power to the motor ση, and turn off the stirrer 6.
Stop 2.

In the extraction operation as described above, when the shake base in the cooling chamber (3) is sent to the mixing chamber (to), the pressure detection device αη detects the pressure drop in the cooling chamber (3), and the pressure switch (17A) detects the pressure drop in the cooling chamber (3). ) is closed. Then, the mix supply solenoid valve opens and supplies the mix in the mix tank (1) to the cooling chamber (3), so that when the pressure in the cooling chamber (3) reaches a predetermined value again, the pressure is reduced. The detection device (17) detects this, opens the pressure switch (17A), and closes the mix supply solenoid valve (161) to stop supplying the mix.

In addition, although the above embodiment described the extraction operation when the extraction command switch (123) is pressed, the extraction command switches (123), (124), (125), and (126)
Depending on the selection, it is possible to freely extract an ice cream shake containing syrup according to one's taste in the same manner as the above-mentioned extraction operation.

The frozen dessert manufacturing apparatus of the present invention has been described using an ice cream shake manufacturing apparatus as an example, but the present invention can be applied to any frozen dessert similar to an ice cream shake, such as soft ice cream, without departing from the spirit of the invention. Of course, it can be applied to manufacturing equipment.

(g) Effects of the invention As described above, the present invention provides the following effects: After stopping the supply of syrup,
Delayed? @Since the supply of confectionery base is stopped, the syrup adhering to the end nozzle of the syrup supply pipe can be wiped away by the frozen confectionery base, and furthermore, after the supply of frozen confectionery base is stopped, the rotation of the stirring blade is stopped with a delay. As a result, there is almost no frozen dessert left in the mixing chamber, and as a result,
This has the excellent advantage that no trace of the previous syrup remains in the frozen dessert extracted by the next extraction operation, and the quality can be improved.
