Description

[0001] Apparatus for drying agricultural and aquatic products [

The present invention relates to a drying apparatus for agricultural and marine products using a negative pressure method for drying various kinds of dried products such as agricultural products and aquatic products at a relatively low temperature at which the nutrients are not damaged.

In order to improve the quality and storage quality of agricultural products such as pepper or herb and fishes, various drying apparatuses have been developed and used to date. In such a drying apparatus, the nutrients, color and biochemical properties It is required that the technology is not provided.

Drying apparatuses which do not deteriorate the dried material are dried under relatively low temperature conditions, that is, they are decompressed to reduce the water vaporization point of the dried material to a low pressure so as to dry quickly without damaging the dried material. Devices are being provided.

Such a drying apparatus of the negative pressure type continuously and repeatedly performs the decompression and the hot air supply process in the drying chamber, and maintains the quality of the dried material and shortens the drying time.

More specifically, the pressure inside the drying chamber is lowered by the decompression means, the air inside the drying chamber is heat-exchanged by using a heater, and then blown into the room using a blowing fan to perform a forced circulation, To achieve the drying of.

However, when the pressure of the drying chamber is increased, the drying efficiency is improved. However, the drying apparatus can not withstand the upward pressure, that is, the drying ability can be improved by the evaporation of moisture and the degree of vacuum. The walls of the apparatus are deformed due to physical shrinkage, so that the decompression pressure in the room is low and the drying efficiency is low.

In addition, the door, which is indispensably provided for the drying and drying of the drying device, is made of a comparatively lightweight material and is opened and closed by a passive operation. Such a passive opening and closing operation is inconvenient for opening and closing the door, Of course, the durability according to the reduced-pressure environment in the drying chamber is poor, and the door is easily deformed.

In addition, the deformation of the lightweight door as described above lowers the degree of airtightness of the drying chamber, which lowers the vacuum and greatly affects the drying efficiency.

Thus, in recent years, a structural innovation of a drying apparatus has been required to solve the above problems.

Domestic Registration No. 0445162

The present invention has been made in view of the above circumstances and it is an object of the present invention to provide a drying apparatus in which a flat plate- To a relatively high sound pressure environment so as to lower the water vaporization point of the dried material and to improve the drying efficiency.

Another object of the present invention is to increase the strength and weight of the door installed for the entrance and exit of the drying device to a high sound pressure environment composition of the drying chamber and to open and close the door automatically, And a drying apparatus for aquatic and marine products.

It is an object of the present invention to provide a drying apparatus for agricultural and marine products using a negative pressure type drying method for drying various kinds of dried products such as agricultural products and aquatic products at a relatively low temperature at which the nutrients are not damaged, And the drying chamber is provided with a drying chamber which is opened and closed by a door as a shaft and closed by a suction pump and subjected to a reduced pressure under a negative pressure by means of a suction pump. The drying chamber is used to dry various kinds of dried products such as agricultural products and aquatic products at a low temperature The apparatus for drying agricultural and marine products of a reduced pressure type is characterized in that the body has tubular pillars arranged at four corners and walls of corrugated shape which are continuously and repeatedly bent and bent several times between the pillars, One pair of the upper and lower sides between the door and the fuselage A rack for driving the front and rear actuators disposed transversely to each other between the door and the moving body and a support shaft for opening and closing the door, A pinion-made opening and closing means integrally installed with the rack, and plate-like heat transfer members on the inner walls of the drying chamber, so that the wall of the drying device is made rigid and the drying chamber is formed into a relatively high sound pressure environment, And the drying efficiency can be further improved.

According to the agricultural and marine products drying apparatus according to the present invention, the flat plate-like walls forming the structure of the drying apparatus are formed by bending continuously several times without increasing the thickness, so that the wall of the drying chamber is made rigid, Thereby lowering the water vaporization point of the dried material and improving the drying efficiency.

Further, according to the present invention, the strength and weight of the door installed for the entrance and exit of the drying apparatus are increased to suit the high-pressure environment composition of the drying chamber and the door of the weight is automatically opened and closed, .

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front view schematically showing the construction of a farming and aquatic products drying apparatus according to the present invention. FIG.
