It is the side view which cut through the principal part which shows one Example of the filtration extraction apparatus for foodstuffs which concerns on this invention, and has added the expanded partial view of the part enclosed with the round line. II-II enlarged sectional end view of FIG. 1

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to examples.

  Below, the filtration thru | or extraction apparatus at the time of the soymilk production | generation at the time of manufacture of tofu is demonstrated about one Example of this invention.

  1 is a heated fluid to be processed as a soymilk raw material, that is, a filter cylinder disposed in a vertical direction having a supply port 2 for soup, and 3 is filtered through liquid components such as slit-like holes or punching holes. A filtering surface 5 having a filtering hole 4 is a rotary scraper mechanism that slides on the inner peripheral surface of the filtering surface 3 to remove solids and effectively performs a filtering action, and includes an arm having a scraper piece 6 7 is fixed to a rotary shaft 8 mounted vertically on the central axis of the filtration cylinder 1 and rotated at a desired rotation speed via a motor 9 and a speed reduction mechanism disposed on the top of the filtration cylinder 1. it can.

  And the said filtration surface 3 faces the bottom face 1d of the wire 1c of the cross-sectional triangle shape which can be engaged with the latching groove 1b provided in the frame 1a of the filtration cylinder 1, and the same circumferential surface as the adjacent wire 1c A slit-shaped filtration hole 4 is formed.

  Therefore, the scraper piece 6 of the rotary scraper mechanism 5 can always slide along the flat circumferential surface α on the filtration surface 3. Moreover, the filtration surface 3 is good also as a punching metal (not shown) which disperse | distributed the hole simply.

  10 is a water storage tank connected below the filtration cylinder 1, and the temperature of the stored water is preferably the same as or close to the supplied fluid to be treated. Filled with water. If necessary, a small amount of ethyl alcohol may be added to impart a bactericidal action.

  11 is a connecting pipe that connects the filtration cylinder 1 and the water storage tank 10, and has two or more water storage tanks provided with a switching valve 12 having a lever as well as an openable / closable function. In the case where 10 are juxtaposed, one water storage tank 10 can be switched to the other water storage tank 10 when the solid content is filled. Note that a ribbon screw (not shown) that interlocks with the rotational force of the rotary scraper mechanism 5 may be provided at the lower portion of the filter cylinder 1 so that solids flowing down do not accumulate.

  13 is an outer cylinder body that can be provided by surrounding the filter cylinder 1 so as to surround the filtered liquid body, and an outlet 14 is provided in the lower part, so that the liquid content of the soy milk to be filtered can be reduced. It can be paid out.

  The operation will be described below under the above configuration.

  The fluid to be treated that is supplied as a raw material is so-called soup that is boiled with soybeans and crushed soy beans, and is supplied to the filter cylinder 1 by applying a desired supply pressure from the supply port 2.

  The fluid to be treated descends along the inner peripheral surface of the filtration cylinder 1, and the liquid component is filtered as soy milk by the rotary scraper mechanism 5 through the filtration hole 4 of the filtration surface 3 to the outer cylinder 13 on the outer periphery. The solid content becomes filter residue (midine) and descends along the inner peripheral surface of the filter cylinder 1.

  Since the water storage tank 10 is connected to the lower side of the filter cylinder 1 through the connecting pipe 11, the descending solid content falls on the water surface of the water storage tank 10 and sinks into the water.

  In this case, since the water in the water storage tank 10 is in a hot water state, surplus liquid components adhering to the peripheral surface of the solid content and nutrients inside the solid content are taken out into the hot water, and a kind of washing and extraction action is performed. There are differences in specific gravity, and the lower part is separated into two layers, ie, solid content at the lower part and hot water at the upper part.

  When the water extraction and washing action in the water storage tank 10 is sufficiently performed, the switching valve 12 of the connecting pipe 11 is closed, the water storage tank 10 is separated from the filter cylinder 1, and the water storage tank 10 In addition to separating and taking out the washed or extracted water and the solid separated by precipitation, the next treatment can be performed, and another parallel water storage tank 10 and a switching valve 12 are connected to each other. The same washing or extracting action can be performed.

  The solid content thus filtered is captured by the water in the lower water storage tank 10 and is effectively subjected to a kind of washing and extraction, and is performed continuously and efficiently. Untreated nutrients are obtained in water, filtered into the outer cylinder 13 and added to the obtained soymilk to adjust the high concentration state to the appropriate concentration of choice.

  Furthermore, the solid content (midine) in the water storage tank 10 can be effectively utilized as a degreased pale white good health.

  As mentioned above, although the case where the to-be-processed fluid mixed with the solid liquid of the soymilk manufacturing process was used about this invention was demonstrated, it is widely drinkable, such as a health food, cooking oil, including other fruits, coffee, tea leaves, seasoning raw materials. When used, it can be used as an apparatus and method for filtering and extracting a fluid to be treated.
