Description

  The present invention relates to a cooling device. More specifically, the present invention relates to a cooling device having an intake port provided in a first chamber, conveyor means for conveying steamed cereals, and an exhaust port provided in a second chamber.

  Conventionally, there is a pot-type fully automatic rice cooking system as a device for cooking many grains at once. In the fully automatic rice cooking system of the pot type, rice is cooked using a batch of a predetermined capacity, and since each is independent, there is an advantage that production of various varieties is easy. Moreover, after cooking using such a system, it can be separated from a kettle into a bakkan (so-called cold box), which can be directly carried into a large refrigerator and cooled.

  However, in the above rice cooking system, since it is directly carried into a large refrigerator, the temperature is lowered from the outside of the backpack, and there is a problem that the cooling rate is slow. Moreover, since the cereal located inside the baccan is kept in a warm state for a long time, there is a problem that the deterioration of starch is promoted and the texture is impaired. In addition, if the cooling rate is slow, there is a problem that the time for which the bacteria are kept in a temperature range (about 35 to 45 ° C.) where the bacteria are likely to propagate is long, and the bacteria are promoted.

  The present invention has been made in view of the problems of the above-described conventional apparatus, and can cool the cereal after cooking quickly and uniformly, facilitating subsequent processing, and preventing deterioration of starch. Furthermore, it aims at developing the cooling device which can shorten the time hold | maintained at the temperature range which is easy to propagate a microbe.

In the cooling device of the present invention, a conveyor means to which rotational torque is transmitted via an electric motor driven by an external power source and one or a plurality of agitators for agitating cereals are disposed in the container,
The container is partitioned by the conveyor means into a first chamber above the conveyor means and a second chamber below the conveyor means,
The first chamber is provided with one or more air inlets and the stirrer,
One or more exhaust ports are provided in the second chamber.

  It is preferable that the exhaust port is an exhaust duct extending from the inside of the second chamber to the outside.

  It is preferable that the conveyor means includes one or a plurality of wheels that are rotationally driven via an electric motor that is driven by external electrodes, and a mesh belt that is wound around the wheels.

  According to the cooling device of the present invention, the cereal after cooking can be rapidly and uniformly cooled. Thereby, since the cereals carried out are not kept for a long time in a temperature zone in which starch in the cereal is likely to deteriorate or in a temperature zone in which fungi are likely to propagate, the whole is cooled uniformly and sufficiently, Various subsequent processing is easy. Moreover, all processes can be performed continuously and automatically with a minimum number of personnel (for example, one person), and production costs can be greatly improved.

  A cooling device according to an embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 1 is an explanatory side view of an embodiment of the cooling device of the present invention. FIG. 2 is a front sectional view of the cooling device of FIG. FIG. 3 is an explanatory view of a stirrer in one embodiment of the cooling device of the present invention. FIG. 4 is an explanatory view of a stirrer in one embodiment of the cooling device of the present invention.

Embodiment As shown in FIGS. 1 and 2, a cooling device 1 according to the present embodiment includes a conveyor means 3 in which rotational torque is transmitted to a container 2 via an electric motor driven by an external electrode. 1 or a plurality of agitators 4 for agitating cereals, and the container 2 is disposed by the conveyor means 3 in a first chamber 5 above the conveyor means 3 and below the conveyor means 3. 1 or a plurality of air inlets 7 and the stirrer 4 are provided in the first chamber 5 and extend from the second chamber 6 to the outside of the second chamber 6. A plurality of exhaust ducts 8 are extended. The exhaust duct 8 is not limited to such a configuration, and an exhaust port (or an exhaust hole) that functions as a simple exhaust opening may be provided.

  The conveyor means 3 includes one or a plurality of wheels 9 that are rotationally driven via an electric motor driven by external electrodes, and a mesh belt 10 wound around the wheels 9.

  The container 2 is provided with a hopper 11 for putting the cereal after cooking into the container 2. The cereal introduced from the hopper 11 falls on the conveyor means 3 and is then conveyed in the first chamber 5 above the conveyor means 3 as the belt 10 advances.

  The conveyor means 3 is rotationally driven by a plurality of wheels 9 around which a belt 10 is wound (five examples are shown in the figure) and a driven shaft of the wheel 9 detachably connected to the output shaft of the electric motor. Is done. Needless to say, the present embodiment includes a reduction gear interposed between the electric motor and the output shaft. In addition, the belt 10 passes between each grain of cereals to be conveyed after the outside air (preferably cold air) introduced from the air inlet 7 described later is introduced into the first chamber 5, For example, a stainless steel net-like belt is preferably used so as to be moved to the second chamber 6. Note that a belt 10 other than a net-like belt 10 such as a belt 10 having a large number of holes may be employed, and at least a belt provided with a gap so that outside air can move from the first chamber 5 to the second chamber 6. There are no problems, and various belts obvious to those skilled in the art can be employed.

  As shown in the figure, the agitator 4 is provided to agitate the cereal to be carried. The rotational drive of the agitator 4 is the same as the rotational drive of the conveyor means 3. The rotational speed of the stirrer 4 is preferably higher than the traveling speed of the belt 10. Actually, in consideration of the convenience of stirring and mixing, about twice the traveling speed of the belt 10 is preferable. The rotating direction of the stirrer 4 can be rotated in any direction, but when rotating in the direction opposite to the traveling direction of the belt 10, the grains traveling on the belt 10 can be efficiently sprinkled. However, depending on the rotational speed, smooth progress of cereals is impeded, and therefore it is preferable to rotate the belt 10 in the same direction as the traveling direction. Further, the distance from the belt 10 when the end of each stirring blade 12 is closest to the belt 10 is preferably about 1 mm from the viewpoint of increasing the stirring efficiency. Generally, cereals that have been cooked have individual adhesion to other cereals, so even if the distance is not shortened until the stirring blades 12 are almost in contact with the belt 10. (That is, even if it is not set to 1 mm or less), almost all grains can be mixed uniformly, and there is substantially no merit by setting to 1 mm or less. On the other hand, when it sets to 1 mm or more, there exists a problem that it may become impossible to stir all the grains uniformly by the adhesiveness which each grain has.

  In the present embodiment, the case where the number of the stirring blades 12 is four is illustrated, but the number of the stirring blades 12 is not limited to this, and various numbers can be selected. From the viewpoint of increasing the efficiency of stirring and mixing, 2 to 8 sheets are preferable. Moreover, although the case where the three stirrers 4 in this Embodiment were provided was illustrated, the number of the stirrers 4 is not limited to this, What is necessary is just one or more. Furthermore, as for the shape of the stirring blade 12 of the stirrer 4, in this embodiment, in addition to that shown in the drawing, the one shown in the drawing may be used, and further, stirring blades of various shapes obvious to those skilled in the art. 12 can be adopted.

  As shown in the drawing, the intake port 7 is a part for introducing outside air into the first chamber 5 of the container 2 by using an intake fan (not shown) as the intake air A1. Further, as shown in the figure, the exhaust duct 8 is for exhausting the cereals through the exhaust fan (not shown) and exhausting the outside air introduced into the second chamber 6 to the outside of the container 2 as the exhaust A2. It is a part of. As described above, since the belt 10 provided in the conveyor means 3 is provided in a net shape, the outside air introduced from the air inlet 7 passes between the respective grains of the cooked cereal, and the first chamber. After moving from 5 to the second chamber 6, the air is exhausted from the exhaust duct 8. In this way, by performing the intake mechanism and the exhaust mechanism via the belt 10 on which the cereal is conveyed, the outside air reliably passes between the cereals, and the cereals are also agitated by the agitator 4 described above. It is possible to cool the grains of each cereal efficiently evenly without forming a lump. Further, since the intake fan and the exhaust fan are driven at the same time, the inside of the container 2 always has a negative pressure, so that fresh air can be always introduced. At this time, since the filter 13 is installed in the intake port 7, no foreign matter is mixed in when the outside air is introduced.

  In addition, it is preferable that the external air taken in from the inlet port 7 is cool air of 20-25 degreeC. The cold air may be adjusted at room temperature. If it is difficult to adjust the room temperature, a circulator for adjusting the cold air may be separately prepared, and may be adjusted as appropriate. When the outside air having such a temperature is introduced, the temperature in the container 2 can be maintained at about 22 to 30 ° C.

  The cereals that have finished cooling are carried out from the carry-out port 14. Since the unloaded cereals are sufficiently cooled, various kinds of processing are easy. Moreover, by rapidly cooling, cereals are not held at a high temperature, and starch deterioration can be prevented. Thereby, it can cool effectively, without being kept for a long time in the temperature zone which promotes reproduction of bacteria.

When the outside air is introduced at an intake air amount of 60 (m ³ / min) using the cooling device 1 of the present embodiment and 1,000 kg of cereal is processed, the cereal introduced at about 90 ° C. from the hopper 11 is The time taken to carry out from the carry-out port 14 is about 6 minutes, and the temperature of the cereal at the carry-out port 14 can be cooled to about 30 ° C.

  As mentioned above, the cooling device of this invention can cool the cereal after cooking rapidly and uniformly. Thereby, since the cereals carried out are not kept for a long time in a temperature zone in which starch in the cereal is likely to deteriorate or in a temperature zone in which fungi are likely to propagate, the whole is cooled uniformly and sufficiently, Various subsequent processing is easy. Moreover, all processes can be performed continuously and automatically with a minimum number of personnel (for example, one person), and production costs can be greatly improved.

  In addition, the cooling device of this invention can cool the steamed cereal more efficiently by using in connection with the apparatus disclosed by patent 3172519, for example. In this case, all the processes can be performed fully automatically and with a minimum of personnel (for example, one person) from the time when the rice requiring washing is put into the apparatus until after the cooling, and the production cost can be greatly improved. it can. In addition, even if it is other than the said apparatus, you may directly throw in the cereal which was cooked with the different rice cooker.
