Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a quality maintenance processing device for food products such as fresh products such as meat, seafood, vegetables, and fruits, and processed foodstuffs such as ham and sausage. relates to an apparatus in which a chemical liquid is carried on a gas flow to form a mist and is sprayed onto food.

"Prior Art and its Problems" Various methods have been proposed to maintain the freshness and quality of food for as long as possible. For example, methods by setting storage temperatures such as low-temperature storage and frozen storage;
Various methods have been proposed, including methods using preservatives, carbon dioxide gas, and chemical solutions.Among these methods, the method of processing carbon dioxide gas (in bulk) allows large quantities to be processed at once with relatively simple equipment. It is one of the processing methods that has been attracting attention in recent years because it can greatly enhance the effects of low-temperature preservation and frozen preservation, and is harmless to the human body.First, this treatment with carbon dioxide gas, It is said that a treatment using various chemical solutions in combination can produce even larger taka fruit than a treatment using carbon dioxide alone.

By the way, when processing using gas and chemical solutions, one important issue is how to spray the chemical solutions onto foods.

In other words, in order to supply chemical solutions to food, are there any methods such as dripping, vaporization, or atomization? Dripping can provide a uniform supply, while vaporization is limited to the type of chemical solution, or requires heating, etc. There is a problem.

If a chemical solution is supplied in the form of a mist, this problem does not occur, or the atomization process usually requires a high-speed gas flow, and this mixed gas flow is directly supplied to the processing vessel. When feeding inside the tank, there was a problem similar to the case of dripping, where the chemicals were burned or left uncooked.
In this case, a mixture of fine (atomized and apricot) gases is supplied into the container, and the chemical solution in the form of water droplets is deposited on nine products. Oh my God.

``Object of the Invention'' The present invention solves the problems of the conventional device described above and makes it possible to atomize water.
An object of the present invention is to obtain an apparatus that prevents the chemical liquid from being directly sprayed onto food products. The purpose is to obtain a device in which large mist is removed in advance, atomized into fine particles, and only the mixed gas is supplied into the processing container. An object of the present invention is to reduce the M of the mixed gas by reducing the space of a sealed storage container when spraying the mixed gas while making it easy to store food.

"Summary of the Invention" The present invention (j) includes an atomizing mixer for a chemical solution and gas to be atomized and supplied to the food, and a food placement section, which is installed in a food processing container. A baffle plate is provided between the container and the placement section to prevent the mixed gas atomized and mixed by the atomization mixer from being blown directly onto the food in the placement section. ing.

In this way, by providing a baffle plate, it is possible to prevent the mixing gas (sprayed from the atomizing mixer) from being sprayed directly onto the food. Large particles collide with the baffle plate and drip.Thus, those that are easy to drip () of the exposed chemical solution are separated and removed by the baffle plate, and become a fine mist of the food. As a result, only the fine mist of the chemical solution adheres to the surface of the food, and the carbon dioxide gas acts with it, which improves the flavor of the food. A good quality retention effect can be obtained without adversely affecting the product.

In a preferred embodiment of the present invention, the baffle plate and the bottom of the processing container are formed into a downwardly convex trapezoidal shape. When the mixed gas is placed in the direction (above the convex baffle plate 1), only the finely atomized chemical solution reaches the food placement area in the processing container, and the atomization is accelerated. A large medicinal solution with a particle size of -1' is enough.
Because dew condenses (collides with the baffle plate) and drips along the baffle plate, insufficiently atomized chemical solution is collected downward and discharged.

In addition, the present invention relates to chemical solution A3 and gas species 8.
C-Is there any special (chemical solution and L/c-aqueous solution mainly containing monoammonium, gas and can.

``Embodiments of the Invention'' The present invention will be explained in detail in the following illustrated examples. This is an example.

A container body 32 with an open bottom surface is fixed to the upper part of the frame 31. Inside the container body 32, the left and right upper ends (this is a pantograph-like telescopic ring) 33 are suspended and supported, and at the lower end of the telescopic ring) 33, for example, several half-layers of netting are placed. Similarly, it is suspended and supported via a shelf 34 or a telescopic rod 35. The telescopic lot 35 is

When the setting is completed, the lid 40 is raised by the air cylinder device 41. Then, the storage shelf 34 at the lowest stage is pushed up in order, and after all the expansion and contraction lots 35 are in the shortest state, the expansion and contraction links 33 are further contracted and the lid body 40 is brought into close contact with the lower surface of the container body 32.

In this clamped state, carbon dioxide gas is supplied from the liquefied carbon dioxide gas cylinder 14 to the spray nozzle] 2. As a result, a mixed gas of a misted ammonia aqueous solution and carbon dioxide gas is sprayed from the spray nozzle]2. Since there is a baffle plate 43 in the jetting direction of this mixed gas, the mixed gas passes through the mixed gas passage 42 from the outside lower part of the container body 32 to the food inside the container body 32 without being sprayed directly onto the food inside the container body 32. It squirts inside 32. The large particles of the atomized chemical solution collide with the baffle plate 43 to form dew condensation, which then travels along the baffle plate 43 and drips onto the liquid fall portion 44. This spray may be sprayed with only a sufficiently fine atomized chemical solution or with carbon dioxide gas (inside the container body 32). Chemical liquid burn can be prevented.Also, since the spacing between the storage shelves 34 is minimized when stored in the container body 32, the space of the storage container 30 is reduced compared to when the spacing between the storage shelves 34 is unchanged. can be reduced to the amount of mixed gas.

The aqueous solution that has fallen into the liquid drop recess 44 is discharged into the exhaust gas treatment water tank 45 via the liquid passage 46. In addition, the mixed gas (exhaust gas) inside the container body 32 (which comes into contact with the food) is blown into the exhaust gas treatment water tank 45 through the exhaust gas passage 47. 48, becomes smaller as it passes through the small hole, and comes into sufficient contact with the water in the exhaust gas treatment tank 45.As a result, the water in the exhaust gas treatment tank 45 becomes ammonia water, so the water supply path 49 and By appropriately setting the speed of supplying and discharging water into the exhaust gas treatment water tank 45 through the water discharge path 50, it is possible to discharge one flow of ammonia water before it reaches the regulated concentration.

The food that has undergone the above processing is sent to the next process, such as being exposed to the outside air, being transferred to a low-temperature refrigerator, or being transferred to a freezer, depending on the nature of the food.

"Effects of the Invention" As explained above, according to the food quality maintenance processing apparatus of the present invention, a baffle plate is provided between the atomization mixer and the mounting section, so that the chemical solution and gas are atomized. This prevents the mixed gas from being sprayed directly onto the food. In addition, large particles of the atomized chemical liquid collide with the baffle plate and drip, and are removed from the mixed gas, so only sufficiently atomized chemical liquid is supplied to the food placement area. be done. By doing so, it is possible to obtain a good quality preservation effect and also to prevent flavor deterioration of foods due to excessive adhesion of chemical solutions. First, if the shape of the baffle plate is a downwardly convex trapezoidal shape, the chemical solution that collides with the baffle plate and drips can be collected and easily taken out from the container. The distance between food shelves is variable, and when the food is stored in the processing container, the food shelves are placed closest to each other, making it easier to set the food on the shelf, while also making it easier to place food in the processing container.
