Abstract

PURPOSE:A baffle plate is set inside the over-flow and a bubble-eliminating plate is set inside the path in which soybean milk flows so that the height of the flow path is lower than the bubble-eliminating plate to remove bubbles formed when soybean milk is packed. CONSTITUTION:The pipe 2 for feeding soybean milk is equipped with a part for allowing the milk to flow out radially from nozzles into the bottom of the vessel 1. A baffle plate 5 is detachably set inside the overflow 9 to control the flow rate and a bubble-eliminating plate 6 is fixed inside the buffle plate 5 so that the height of the path of the milk flow formed under the end of the baffle plate 5 is made lower than that of the eliminating plate 6.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is an air bubble removal device that is indispensable for ensuring the quality of food products, especially for removing bubbles that inevitably occur during the filling process of highly foamable soymilk solutions. (Interfacial Chemistry 2nd Edition 1GIP, where each bubble is a bubble and the state where a large number of bubbles are gathered is called a foam) is related to a device that efficiently removes air bubbles.

[Conventional technology]

In an apparatus for filling a fixed amount of a protein solution such as a soybean milk solution into a container, generally a part of the soybean milk solution is received by an air cylinder or the like, and the soybean milk solution is forcibly injected directly into the container by adjusting its stroke.

A large amount of foam was generated in this forced filling method, especially in the filling process of a highly foaming soymilk solution. If some of these air bubbles get mixed into the product, it not only naturally reduces the product value, but also causes oxidation and spoilage after shipping, so to ensure product quality, these air bubbles must be removed. I had to.

Conventionally, various methods have been employed to remove these bubbles, but none of these methods is satisfactory in terms of quality or cost. An example of the prior art will be described below with reference to FIG.

In other words, the soymilk solution injected from the milk storage tank (a) through the air cylinder (b) into the container (6) inevitably generates a large amount of foam due to the injection pressure and head pressure, so it is At the same time, remove all the foam and foamy solution using Qft, and refill the removed amount with pipe (b).
After replenishing, vacuum packaging is performed.

[Problem that the invention seeks to solve]

The purpose of the present invention is to completely remove the foam that occurs when filling a foamable protein solution such as a soy milk solution, and to solve the problem of significant manufacturing loss caused by this. .

[Means for solving problems]

In the present invention, an injection pipe having a plurality of pouring ports is provided in the upper surface open receiver near the bottom of the container, and a soybean milk solution injection port is provided on one side wall of the container, and air bubbles are formed inside the same-temperature outlet. A soybean milk solution flow path is formed at the bottom of the partition plate, and a bubble prevention plate is provided inside the flow path, so that the straightness of the flow path is lower than the height of the prevention plate. It consists of a solution bubble removal device.

[For production]

The structure of the receiving container is as described above, so the soymilk solution to be filled passes through the injection pipe and from the spout at the bottom of the receiving container, in a state where outside air is blocked and no air bubbles are generated. A fixed amount will be supplied.

〔Example〕

The present invention will be explained below based on embodiments shown in the drawings.

FIG. 1 is a basic process diagram for filling a soy milk solution using the present invention. The soy milk solution Q4 in the milk storage tank αQ is.

The air is sent to the air cylinder (b) and a fixed amount is sent to the receiving container (
1) will be supplemented. This fixed amount is the same amount as the content of the filling container (2). When the next fixed amount of soymilk solution 04 is fed into this receiving container (1) from the air cylinder, the fixed amount overflows from the overflow port (9) and is filled into the filling container 02. The filled container (2) sent out through this process is vacuum-packed with a film aυ welded to it in a bubble-free and fixed amount state.

FIG. 2 is a plan view of the container (1).

The third factor is the sectional view taken along line I'-'I in FIG.

The wooden receiver is composed of a container (1) that receives the soy milk solution Q4 sent out from the cylinder (b) and guides it to the container (1) (injection pipe!
21 and the tip of the injection tube (2) are screwed with metal fittings (3) for dispersing the soy milk solution Q4 radially from the spout (3γ) to the bottom of the receiving container (1). It is sealed at the bottom and attached with bolts and nuts (4).Next, a removable partition plate (5) is installed inside the overflow port (9) of the receiving container (for the flow rate Mfi). A bubble prevention plate (6) is attached to the inside of the container (5) from the bottom of the receiving container (1).The height of the soy milk solution flow path formed under the partition plate (5) It must always be lower than the height of the contamination prevention plate (6).

The fitting for solution diffusion and replenishment (3) at the tip of the injection tube (2) for injecting soymilk solution is placed in the liquid at the level - of the soymilk solution o4 determined by the installation height of the overflow port (9). Because it is close to the bottom of the container (1), the spout (3
)' to the receiving container (1) with the soybean milk solution α→ being always shut off from the outside air, so that the replenishing solution is supplied without generating air bubbles. Even if air bubbles occur, the receiver will not be able to handle the inner wall of the container (1), the prevention plate (6), the partition plate (5).
), the liquid rises to the water surface) and bubbles break or disappear.

The soybean milk solution Q4, which was fixedly injected into the container (1), flows from the overflow port (9) by the amount of quantitative replenishment, and is successively transferred to the container @ which has been moved on the belt conveyor (B). The film is then welded to form the product. In addition, very few air bubbles are generated when the soy milk solution α→ overflows from the overflow port (9) into the container (2) and is filled.
Although this is unavoidable due to the differential pressure between the overflow port (9) and the container (2), the overflow port (9) is set to be inclined so that the water flows down into the container (2) from the inner wall surface of the container (2). Head pressure is kept to a minimum. Therefore, the few air bubbles that may be generated will completely disappear during the process of wrapping the film O→ at f8@ and vacuum packaging.

〔Effect of the invention〕

It has become possible to omit the replenishment process associated with this process, completely eliminate product losses associated with losses and defects in these processes that previously occurred, and to stably supply the targeted bubble-free soy milk products to the market.

Furthermore, the device of the present invention has the advantage that it can be widely used in fields that require the removal of air bubbles from foamable protein solutions, foamable egg tofu, stuffed tofu, and other foamable concentrated fruit juice and vegetable juice solutions.
