多かった。As described above, when air is ventilated through the heating raw material for continuous cooling, the heating raw material is designed to be cooled to a predetermined temperature if it uniformly passes through the heating raw material. Has been done. However, when ventilation is performed from above to below, the heating raw material is pressed against the conveyor belt and compressed by the passage resistance of the air when the air passes through the heating raw material, and as a result, the passage resistance of the air increases. Will end up. When the heating raw material contains a large amount of water or the heating conditions are not appropriate, air may hardly pass through. In particular, the tendency is remarkable in soybeans and defatted soybeans, which are heating raw materials having a high water content and steamed, and defatted soybeans, and white rice and soybeans, which are raw materials for sake and miso. Further, not only the resistance of air in the heated raw material, but also the air passage resistance is increased by pressing the heating raw material into the air passage openings in the conveyor belt to close the openings. In particular, the tendency is remarkable in the case of the heated raw material which has been steam-treated as described above having a large water content. Therefore, in the case of the method of ventilating from the upper side to the lower side, it is often impossible to obtain the desired cooling capacity.

用されてなかった。On the other hand, in the registered utility model, a method of ventilating the heating raw material from below to above is also proposed.
The proposed method is to suck and exhaust by a fan installed above the heating raw material.For example, like roasted rice and wheat, the heating raw material has a relatively low water content and is sufficiently contained in the heating raw material. In addition, if there is a uniform space, the desired cooling capacity can be obtained. However, in the case of a heated raw material containing a large amount of moisture as described above, the passage resistance in the heated raw material is large, and due to the structure of the cooling device, it is not possible to sufficiently seal the inlet and outlet of the heated raw material. Because of this, there is a drawback that the amount of inflowing air from the outside increases, and it is difficult to ventilate the heating raw material, so this method has hardly been adopted in the past.

提供を主要課題とするものである。Further, since the heated raw material is subjected to further processing in the next step after the cooling treatment, it must normally have an appropriate product temperature. However, in the conventional cooling treatment method, the outside temperature condition when the cooling treatment is performed, the heat treatment condition, the moisture content of the heating raw material and the like are not constant, so that the product temperature after the cooling treatment is not constant, so that it is accurate. The reality is that the product temperature control is not done properly. Considering these circumstances,
In the present invention, it is possible to perform an effective cooling treatment even for a steaming raw material having a particularly high water content, and to provide a heating raw material cooling method and apparatus capable of accurately controlling the outlet side product temperature, To do.

And a blowing means having a blowing pressure and a blowing amount capable of passing through the heated raw material deposited on the conveyor belt are connected to the wind tunnel, and the air is accumulated on the conveyor belt through the conveyor belt. The heating raw material was decided to be cooled by ventilation from below.

処理が図られる。The heating material deposited on the conveyor belt is provided with an air blowing unit having a blowing pressure and an air blowing amount capable of passing through the heating raw material and venting to the upper side below the heating raw material deposited. No more compression and no clogging of the conveyor belt holes, and good cooling was achieved. In addition, it was not possible to sufficiently ventilate the heated raw material accumulated on the conveyor belt with a fan, but it was necessary to ventilate the heated raw material deposited on the belt from below the conveyor belt. If air with a blowing pressure as much as possible is supplied, the air has to pass through the heating raw material, so almost all of the blown air passes through the heating raw material, and effective cooling treatment is achieved. .

設することにより実現される。In the invention described in claim 2,
In the method for cooling the heated raw material, the heated raw material is made to be in a substantially dispersed state before being deposited on the conveyor belt. As described above, when the heated raw material is ventilated and cooled from above, the raw material compression and the clogging of the conveyor belt holes are less likely to occur, but when the heated raw material is accumulated on the conveyor belt, the heated raw material is already removed. When in a compressed state, for example, in a solidified state, the effect of ventilation cooling becomes small. On the other hand, if the heating raw material is unraveled by a crusher or the like after being deposited on the conveyor belt, there is a disadvantage that the heating raw material cannot be sufficiently unraveled,
Further, if the raw material contains a large amount of water, the opening of the conveyor belt may be clogged by the rotation of the crusher. Therefore, in the present invention, the heating raw material is loosened in a substantially dispersed state before the heating raw material is deposited on the conveyor belt, and even when the heating raw material is deposited on the conveyor belt, it is easy to ventilate the heating raw material and aeration cooling is performed. The effect of was improved.
In order to loosen the heating raw material into a substantially dispersed state, a crusher in which a shaft on which a plurality of rods or plates are mounted substantially vertically can be rotated vertically or horizontally is preferably used. It is realized by arranging it on a substantially vertical line below.

When air is blown to the heated raw material in a substantially dispersed state, the product temperature becomes lower than usual due to the latent heat of vaporization, and the surface of the heated raw material dries due to moisture evaporation, so even after being deposited on the conveyor belt, the heated raw material The space between them is maintained, and the efficiency of heat exchange by the ventilation air is improved. On the other hand, when the air-cooled material is not dispersed and the air-cooled material is almost dispersed, the heated raw material is once sparsely deposited on the conveyor belt, but it is difficult to maintain the voids between the heated raw materials. The cooling efficiency will be slightly reduced.

である。Further, in the invention described in claim 5, the dispersing means is arranged between the feed port of the cooling device and the conveyor belt for the heated raw material. Ventilation cooling is performed while unraveling the heated raw material in a substantially dispersed state before it is deposited on the conveyor belt, while it is easier to ventilate the heated raw material when it is deposited on the conveyor belt to improve the effect of aeration and cooling. It was planned.

た。The condition of the ventilation air in such a cooling device is stable for a certain short time if, for example, outside air is used, so that the product temperature of the heating raw material after the cooling treatment is set to a predetermined value. Can be realized by controlling only the ventilation volume. From the above point of view, in the invention described in claim 6, a temperature sensor for measuring the product temperature of the heating raw material is provided in the vicinity of the outlet of the cooling device configured as described above, and the air flow rate of the air blowing means is based on the product temperature information.

なった。Since the amount of air blown is almost proportional to the number of revolutions of the air blower, it can be easily controlled by connecting an inverter to the motor of the air blower that serves as the air blowing means. As a control method, the product temperature value is fed back and the rotation frequency of the blower is determined based on PID calculation, or the rotation frequency of the blower is determined based on the result of the production rule by inputting the product temperature value and the outside air condition to the control device. Or a method of controlling the value according to the deviation between the set product temperature value and the measured product temperature value for every predetermined time with respect to the rotation frequency of the blower in a stepwise manner. In this way, accurate control can be performed so that the product temperature of the heating raw material after cooling becomes a predetermined value.

回転周波数等を随時設定するなどの方法が挙げられる。On the other hand, since the air discharged from the heated raw material deposited on the conveyor belt has a high temperature and a high absolute humidity, if it leaks into the room, it will cause dew condensation on the ceiling and wall surfaces of the room including machinery. Since dew condensation causes contamination of various bacteria, such air is exhausted directly to the outdoors in food manufacturing plants and the like. However, when the product temperature of the heating raw material is controlled by the blown air amount as described above, the blown air amount changes every moment, so that the amount of air discharged from the accumulated heating raw material also changes. Depending on the season, or if there is a large difference in temperature between days, one of the blowers installed
The heating raw material may be cooled too much below a predetermined product temperature so that one or a few units must be completely stopped. When the amount of blown air changes greatly, naturally the amount of exhausted air from the accumulated heating raw material also changes greatly. Therefore, the amount of exhausted air from the heated raw material and the amount of exhausted air from the exhausting means that exhausts it outside (outdoors etc.) If the balance is set so that the amount of exhaust air of the exhaust means is slightly larger, the air that causes dew condensation will leak into the room.
Therefore, in the invention described in claim 7, the control means in the cooling device also controls the exhaust air volume of the exhaust air means connected to the hood arranged above the conveyor belt in accordance with the air flow rate of the air blow means. So formed. As a control method,
There is a method of setting the rotation frequency and the like of the air exhaust unit at any time according to a comparison table provided in advance according to the number of operating air blowers and the rotation frequency of the air blowers.

回転周波数等を随時設定するなどの方法が挙げられる。On the other hand, since the air discharged from the heated raw material deposited on the conveyor belt has a high temperature and a high absolute humidity, if it leaks into the room, it will cause dew condensation on the ceiling and wall surfaces of the room including machinery. Since dew condensation causes contamination of various bacteria, such air is exhausted directly to the outdoors in food manufacturing plants and the like. However, when the product temperature of the heating raw material is controlled by the blown air amount as described above, the blown air amount changes every moment, so that the amount of air discharged from the accumulated heating raw material also changes. Depending on the season or if there is a large difference in temperature between days, you may need to install one or more blowers.
The heating raw material may be cooled too much below a predetermined product temperature so that one or a few units must be completely stopped. When the amount of blown air changes greatly, naturally the amount of exhausted air from the accumulated heating raw material also changes greatly. Therefore, the amount of exhausted air from the heated raw material and the amount of exhausted air from the exhausting means that exhausts it outside (outdoors etc.) If the balance is set so that the amount of exhaust air of the exhaust means is slightly larger, the air that causes dew condensation will leak into the room.
Therefore, in the invention described in claim 8 , the control means in the cooling device also controls the exhaust air quantity of the exhaust air means connected to the hood arranged above the conveyor belt in accordance with the air flow quantity of the air blow means. So formed. As a control method,
There is a method of setting the rotation frequency and the like of the air exhaust unit at any time according to a comparison table provided in advance according to the number of operating air blowers and the rotation frequency of the air blowers.
