Description

[Detailed description of the invention] This invention particularly relates to a continuous automatic rice cooking device.

Specialized rice cooking facilities such as school lunch centers that supply rice in bulk to places that consume a large amount of rice, such as servants, schools, cafeterias, hospitals, and sushi restaurants, use rice cookers to cook large quantities of rice. A large quantity of rice is prepared, and soaked rice is placed in these along with water, and while being moved on a conveyor, the rice is sequentially passed through automatic rice cooking means, steaming means, automatic reversing means, and washing means provided at appropriate locations on the conveyor. Circulating devices are commonly used. However, conventionally, this device
Because we were searching for a method to scrape off the rice that fell into the hopper at the automatic reversing means, and then put the rice cooker on a conveyor and send it to the next cleaning means, we were unable to remove any leftover rice, starch, etc. that remained in the rice cooker. There was a problem in that the solids were baked into the interior of the rice cooker due to residual heat before being conveyed to the cleaning means, and could not be easily removed even if hot water (5000 to 6000 ml) was strongly sprayed by the cleaning means.

The present invention solves this problem and aims to provide a continuous automatic rice cooking device in which leftover rice and solid matter remaining in the rice cooking pot are easily peeled off and removed during cleaning.

This invention will be explained in detail below based on the drawings.1
1 is a rice distribution means consisting of a hopper that stores boiled washed soaked rice sent from an Enoki tank (not shown), and this rice distribution means 1 is operated by push button operation or limit switch etc. The device is configured to discharge a predetermined amount of soaked rice and water from its outlet. 2
It is an aluminum alloy or stainless steel rice cooker with a diameter of about 70cm and a depth of about 20cm. ``Although only one is shown in the diagram, there are many available.

3 is a conveyor for transporting this rice cooker 2, and in the example, the part that is not heated is a low-fu conveyor 3a,
The part to be heated is composed of, for example, a chain compare 3b.

Reference numeral 4 denotes an automatic rice cooking means equipped with, for example, a large number of gas burners, and this automatic rice cooking means is attached with a cooling means 5 (indicated by a dotted line in FIG. 2) for cooling the chain conveyor. .

6 is the steaming means that constitutes the heat retention process.
It has a tunnel-like shape and has a heat retention function.

? is an automatic reversing means for a rice cooker equipped with a lid removal device (not shown). ``This device 7 lifts the rice cooker 2 diagonally and then turns it over vigorously to remove the rice inside the hopper ( (not shown), but if you do that, some rice will remain in the rice cooker 2, so it is necessary for someone to be there to scrape off the remaining rice with a spatula, etc. The dropped rice is loosened by an automatic loosening machine (not shown) installed in the hopper, and then placed in a fixed amount in a food can 8 installed below the outlet of the hopper, where it is sealed. ``We'll have to wait for the shipment.
If there is time before shipping, it may be temporarily stored in a refrigerator. 9 is a water injection means according to the present invention, and this water injection means is activated by, for example, a push button operation or a limit switch, and after a certain amount of hot water or cold water is poured into the rice cooker 2, it automatically stops. It has a structure that repeats operations.

Note that it is economical to use the warm water (12 qo to 1500 qo) directly from the cooling means 5 used to cool the chain comperor 3b in the automatic rice cooking means or steaming means described above as this hot water, but it is also possible to use separately heated water. You can also use something. Ordinary tap water may also be used. 10 is a cleaning means constituting the cleaning process, which includes a limit switch or
The rice cooker is activated by pressing a button, etc., and after the rice cooker is turned over, compressed water is vigorously sprayed into the rice cooker.

Now, to explain the case of continuously automatically cooking soaked rice using this device, the rice cooking pot 2 (only one is shown) placed on the conveying comparer 3 is heated in advance by the rice distribution means 1. After a predetermined amount of soaked rice and water are injected and the lid is placed, the rice is fed into the automatic rice cooking means 4 that constitutes the rice cooking process, and then slowly passed over the chain comparer 3b for about 23 minutes. As it moves, it is heated and cooked by the gas burner flames blown from all directions, and in the latter half of the process, it is baked.

The rice cooker 2 containing the cooked rice is sent through a chain comper 3b into a steaming device whose upper part is covered to keep it warm, and slowly passed over the chain comper 3b for about 30 minutes. During this time, the rice is steamed. After completing this steaming process, the rice cooking pot is then sent to the automatic reversing means 7, where the lid is automatically removed, the rice is turned over, and the rice is dropped into a hopper (not shown). After being scraped off with a spatula or the like, it is placed on the transport conveyor (low-fu conveyor 3a) again, where approximately 250cc to 500cc of hot water is injected by the newly installed water injection means 9. .This hot water is used to cool the chain compare in the automatic rice cooking means 4 and the steaming means 6, and the hot water heated to about 1 to 1500 may be used as is, or it may be heated separately. As mentioned above, the rice cooker 2 filled with hot water is sent to the next cleaning process on the conveyor comper, but during this time, any leftover rice or solid matter that has stuck to the rice cooker is removed. The rice is soaked in the warm water without burning into the rice cooker.

The rice is then sent to the cleaning means 10 that constitutes the cleaning process, is automatically turned over, and is cleaned by spraying compressed water from the surrounding area. The material was soaked without burning in the rice cooker, and was easily peeled off and cleaned by spraying with compressed water. In the experiment, warm water was first used, but when regular tap water was used as is, it was found to have a similar peeling effect. The rice cooker that has been cleaned in this way is moved again on the conveyor comper and returned to the rice-saving water distribution means 1, where it passes through the previously mentioned process means in order. By repeating this process, It is capable of producing rice in large quantities. Furthermore, as another embodiment, when a small amount of a starch dissolver such as dichloric acid is added when hot water is injected into the rice cooker using a water injection means, it has been found that the effect of removing solids is further increased. Ivy.

As explained in detail above, this invention adds a water injection means to the conventionally known automatic rice cooking device, so that the leftover rice and solid matter remaining in the rice cooker can be cleaned off during cleaning. As a result, it is possible to achieve a great effect in terms of hygiene, and it is also possible to have the effect of eliminating the need for manpower to scrape off the dirt, as in the case of a sub-chassis.

Furthermore, hot water (5000 to 600
As a result, it is now possible to use cold water instead of using hot water (°C), which has the effect of significantly saving the fuel required to produce hot water.
