を満足する含浸処理装置が望まれている。BACKGROUND OF THE INVENTION Prior to food processing of cereals (eg, rice, wheat, soybeans, buckwheat, etc.), washing or peeling of cereal grains, or harmful substances or proteins present on the surface or inside of the cereal grains are performed. Impregnation with a solution is effective for removal. In addition, as one of the processing methods of cereals, a steaming operation is generally performed, but impregnating the cereal grains with a solution used for steaming prior to the main treatment is effective in shortening the steaming time or improving the taste. It is known that The impregnation treatment can be performed by immersing the target grain in a solution and leaving it to stand. However, there is no industrially known apparatus for efficiently impregnating a large amount of grain grains. Therefore, the impregnation processing that satisfies various requirements such as time reduction, efficient work, or improvement in yield rate is not known. A device is desired.

It is known that food-allergic patients eat harmful substances that cause allergic symptoms, that is, allergen molecules are included.Allergen-removed cereal grains obtained by removing allergen molecules from cereals are used to treat food allergic patients. Used for meals. In addition, it is estimated that the number of patients who need diet therapy for kidney disease is estimated to be 200,000 nationwide,
It is still increasing. In these patients,
There is a high social need for kidney disease patients because the intake of low-protein cereals leads to suppression of protein intake.

た。However, in these conventional methods for producing allergen-reduced rice or low protein rice, the production efficiency is high, and rice grains are crushed and / or powdered. Has not been satisfied at the same time. That is, in these conventional methods, the solution and the rice grains are put in a container and stirred by a stirrer, or the whole container is rotated to perform the reaction. During the process, the rice grains collide with each other, and the rice grains are crushed or powdered by mechanical action. In order to prevent the crushing or pulverization of the rice grains, it is effective to leave the rice grains still, but in this case, there is a disadvantage that the reaction does not proceed efficiently.

It is necessary to add approximately 0 times the solution for the treatment. Therefore, in the actual manufacturing process, the processing tank is filled with the rice grains and the processing solution, and the processing is performed for a certain period of time. Therefore, the amount of rice grains that can be filled with respect to the volume of the reaction tank is １ ／ or less. There is a problem of inefficiency. For example, JP-A-8
According to the apparatus disclosed in Japanese Patent Publication No. -187053, according to the results of the present inventors, the enzyme solution requires a volume four times or more the size of rice grains. 1/4 or less.

ない。In the "relatively long contacting step", the grains are allowed to stand in the impregnating liquid for a time sufficient to substantially impregnate the grains with the impregnating liquid. be able to. "Sufficient time for the impregnation liquid to substantially impregnate the grain" is, for example, a value that varies depending on the type of grain to be treated and the type of impregnation to be performed. Although it cannot be defined, for example, when a rice grain is subjected to an alkali treatment or an enzyme treatment, usually 10 minutes to 4 hours (preferably 20 minutes to 2 hours,
More preferably, it is 20 minutes to 40 minutes). In addition, the "stationary" in this step means that the grain to be treated is allowed to stand still in the reaction tank for performing the impregnation treatment, and the grain for the impregnation treatment liquid is It does not necessarily mean that it is allowed to stand still. For example, in the method of the present invention, in order to eliminate the influence on the grain shape of the grains to be treated, this step is usually carried out with the impregnating liquid kept stationary. The process can also be carried out with the liquid being stirred or circulated slowly (ie, at a rate that is low enough to not affect the retention of the grain shape of the grain). In the latter case, the cereal grains to be treated are left still in the reaction tank for performing the impregnation, but not in the liquid for the impregnation.

た。As described above, the apparatus of the present invention (including the first apparatus according to the present invention and the second apparatus according to the present invention) includes a grain to be impregnated and a grain for impregnation used for the treatment. The liquid can be separated from the liquid, and the grain is brought into non-contact with the liquid for impregnation at least once (preferably, the contact and non-contact of the liquid for impregnation with the grain are repeated a plurality of times). Thus, the impregnated grain is efficiently obtained. In the allergen reduction treatment or low protein treatment, the concentration of the drug used for the enzyme or other treatment is usually relatively low for the purpose of efficiently promoting the protein removal reaction and for the purpose of preventing the damage and dissolution of the grain surface. It is necessary to keep the volume of the impregnating liquid used more than twice the volume of the grain to be processed. Therefore, in the case of the conventional device,
For example, put the grains and the impregnating liquid in the grain storage reaction tank and stir the vessel, or stir with an internal stirrer, or circulate the solution while keeping the grains still. In each case, the amount of cereal grains that could be treated was less than half that of the reaction vessel, which was inefficient.

It is characterized by separating the grains to be treated and the liquid for impregnation treatment used in the treatment, and it is possible to store the grains of the same volume as the capacity of the storage tank in the storage tank and perform the impregnation processing. It is. However, it is necessary to consider that the volume of the grains increases due to water absorption and swelling. For example, the amount of grains to be stored needs to be 70 to 95% of the volume of the storage tank. Therefore, according to the apparatus of the present invention, it is possible to obtain a large amount of treated grains at a time more efficiently than the conventional apparatus, and the apparatus of the present invention can perform allergen reduction treatment or reduction using an enzyme solution, acid, or alkali solution.
