Abstract

PROBLEM TO BE SOLVED: To provide a stirring apparatus capable of dissolving, mixing, and stirring raw materials efficiently without using stirring blades and having high level sanitary capability and cleaning capability in mainly food and pharmaceutical product production fields.SOLUTION: The shaking mixing stirring apparatus can stir a content liquid by generating centrifugal force and inertia force in the content liquid in the inside of a container 1 by outside force without using stirring blades or baffle plates. As a result, since both a motor and a shaft seal part for driving stirring blades do not exist in the container and washing of stirring blades is unnecessary, the stirring apparatus can maintain high level sanitary capability. Further, since the container body does not rotate, stirring is made possible with no need of detaching a pipe (flexible hose) and while keeping the connection of the pipe to a liquid inlet and a discharge outlet during the stirring and stirring is made possible in completely aseptic environments if the container is made to have a closed structure and at the same time, heating and cooling operation is made possible by a warming and cooling jacket.

Description

The present invention relates to a stirring device in the food / pharmaceutical industry. In industry, there are generally stirring apparatuses using stirring blades and stirring blades as chemical apparatuses. These have stirrer blades and stirrer blades according to purposes such as settling prevention, mixing, dispersion, and homogenization, and are used properly according to the application. However, in the food / pharmaceutical industry, high sanitary properties are required due to the characteristics of the products, and it has been necessary to develop a device with high detergency without liquid accumulation.

Conventional technology and background

In the conventional stirring apparatus, the optimum shape of the stirring blade is selected from various shapes depending on the amount of product to be stirred, viscosity, liquid characteristics, and the like. That is, in order to optimally stir the product, it is difficult to perform liquids having different properties in the same container and the same stirring blade, and a plurality of stirring devices are required depending on the liquid quality.

In ordinary chemical plants, the shape of the blades, in particular, emphasizes the stirring performance, and most of them are not aware of the sanitary and cleaning properties required by the food and pharmaceutical industry. In the industry considered as a user of shake mixers, the structure and function of the blades considering not only the stirring performance of the product but also the cleaning performance of the apparatus are required and regarded as important.

The present invention is a device for stirring a product with a completely new concept as a stirring device for the food and pharmaceutical industry. This device is characterized by the fact that it does not have the stirring blades (blades) that are always used in conventional stirring devices, and the product itself generates kinetic energy by the inertia energy of the product itself to stir the product. .

This device transmits the power of the electronic servo motor and the electronic servo cylinder to the thrust turntable, fixes the container on the turntable supported by the device mount, and gradually transmits the drive energy to the container. Obtain agitation energy by gradually amplifying inertial energy.

This device must be capable of handling agitation of various products by combining the above drive unit and a container with a shape designed according to the amount, viscosity, and liquid characteristics of the liquid to be agitated.

Problems to be solved by the invention

To provide the ultimate sanitary environment by providing a stirrer without a stirring blade (blade) to a user who requires sanitary properties and cleanability of a conventional stirrer according to the present invention.

According to the present invention, a process requiring agitation can be continuously processed in a sealed container environment instead of a badge process, and a process in a completely aseptic environment can be realized, and a process for cleaning apparatuses and pipes between processes. To provide an unprecedented aseptic environment.

Means for solving the problem

The shape of the container attached to the shake mixer varies. The mixer control method varies depending on the rotational energy (forward / reverse rotation 0 to 250 rpm) and the eccentricity of the shaft center (± 20 mm), and various combinations of these depending on the amount, viscosity, and liquid characteristics of the stirring object. Suitable for various agitation applications. The shape of the container is a cylinder, prismatic cone, pyramid, unequal side prism, unequal side pyramid, etc., giving an unbalanced weight balance to create the liquid inertia, and forming a smooth protrusion (depot) inside the container. The liquid can be diffused and various stirring effects can be obtained.

All of the containers having the structure as described in item 0009 have a sanitary design (a structure in which there is no liquid accumulation and is easy to clean), and there are no wings or blades in the container, and the cleaning performance is excellent. Since these containers can be easily attached and detached, if a plurality of containers having various shapes are prepared in one shake mixer, various stirring conditions can be handled by one apparatus.

Since the container of this device can be stirred by the inertia of the liquid without rotating, for example, a flexible hose is connected to the nozzle of the liquid container, and a flexible hose for discharging the product is connected to the end of the liquid outlet valve. Since the agitation operation can be performed, the liquid can be charged while stirring, the raw materials can be charged, and the stirred product can be discharged without removing the flexible hose. In addition, by attaching a jacket for heating / cooling to the container and circulating the hot refrigerant through a pipe connected by a flexible hose, the heating / cooling process of the product can be performed in a sealed state.

Claims (3)

Without using a stirring blade (blade), the container body containing the raw material is rotated forward and reverse by external force from the outside and the shaft center is decentered to generate centrifugal force and inertial force in the inner solution. A stirring device for mixing, dispersing, and homogenizing a solution (or powder). The movement transmitted to the container by the agitator described in the previous item is generated by the rotation and lifting movement of the electronic servo motor and the electronic servo cylinder below the container. In order to perform fine-grained control, the initial speed, acceleration time, deceleration time, motor rotation speed and axial center positioning of the servo motor are controlled independently, and the type, quality, characteristics, A stirrer that controls the movement of the liquid (powder) in the container freely by changing the shape of the container according to the purpose of stirring and the shape of the container, and a stirrer having automatic control software for controlling this. . In order to smoothly transmit the centrifugal force and inertia force generated by the electronic servo motor of the preceding item to the container, the stirring apparatus has an independent two-stage thrust turntable suspended by a rod end with a position higher than the center of gravity of the container as a fulcrum. .
