Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehumidifying dryer for cold and hot air for agricultural and marine products,

The present invention is to dry a variety of agriculture and aquatic products by a system of cold air or hot air or dehumidification, and to provide a uniform and stable drying environment to all the objects to be dried in the drying chamber, thereby improving the quality and shortening the drying period The present invention relates to a dehumidifying and drying apparatus for cold and hot air for agricultural and marine products, which can greatly contribute to overall cost reduction required for drying due to minimization of energy loss.

As a method for artificially drying various kinds of agricultural products (red pepper, radish, persimmon, dried herb, shiitake, ginseng, etc.) or aquatic products (squid, anchovy and steaming) by a machine, A hot air drying method comprising blowing hot air of a predetermined temperature into the drying chamber arranged in multiple stages and appropriately supplying and circulating the hot air is well known.

However, since the hot air dryer is a very simple method of transferring the high temperature heat generated from the heater to the pin structure, it is relatively inexpensive and has the advantage of quick drying, There is a disadvantage that it is difficult to apply such a product in case of an item (seafood, persimmon, etc.).

Of course, it is required to install an expensive low-temperature system (a compressor, a condenser, a heat exchanger, etc.) and a dehumidifier by performing drying in a low-temperature and dehumidifying atmosphere that does not transfer heat to the drying of the article, (Cold air) dryer, which not only can effectively dry the product but also has superior drying quality, is widely known.

In recent years, as the functions of the stagnant hot air dryer and the low temperature dryer are provided together, the use of the hot air or the cold air drying capable of selectively performing the hot wind or the cold wind drying has been developed.

However, the existing hot air dryer, low temperature dryer or cold / hot air dryer used for drying agriculture and aquatic products is mainly used for drying (hot air or cold air and dehumidifying function) Because it is designed and manufactured as a small structure of ~ 10 pyeong,

In the case of constructing a system for drying a large amount of laundry, the flow and circulation efficiency of the air stream (hot air or cold air and dehumidification function) required for drying are greatly reduced, and the loss rate of energy is large, There is a problem in that it has a certain limit in obtaining a uniform and excellent drying quality.

That is, the patent registration No. 10-0327303 (the method and apparatus for drying cold and hot winds of agricultural and marine products), which is registered in Mar. 23, 2002,

The dry air preheating step 101 and the moisture removing step 102 in the drying method for the combination of the cold wind hot wind and the dry air preheating step 103 are the same as the drying air preheating step 103 and the dry air reheating step 104, (Hereinafter, referred to as " water < / RTI > products ") carried out in the order of the heat exchanger 106, the external air inflow process 106 ', the mixed air circulation process 107, Drying method for cold winds and hot winds.

In the drying chamber housing 1A, a drying chamber 1B is formed in the air chamber, a mixed air inlet 1B 'is formed at one side thereof, and a dryer unit 1 is installed at the other side. A plurality of fans 1 'are provided on the upper front surface of the dryer unit 1 and a preheating coil 2a and a main cooling coil 1a are installed in an inner middle portion of the dryer unit 1. A preheating heating coil 4a, And a main heating coil 3a are installed on the upper part of the drying chamber 1B and a drain fan 6a is installed on the lower part thereof. The air air-hole shield 3, and the circulation fan 4 are installed. "

10, the hot air or the cold air generated by the dryer unit 1 or passing through the steam 2 passes through the air circulation path and the circulation fan 4, which are provided on the drying chamber 1B, The hot air or cool air introduced into the drying chamber flows into the drying chamber through the air flow rate regulating plate while the lower end portion of the upper end of the drying chamber 1B is bent downward. The drying unit 1B may be moved to the front side of the drying chamber 1B and recovered to the dryer unit 1, and drying may be performed by repeating this flow continuously. However,

Since the air flow of the cold air or the warm air necessary for drying flows in the drying chamber 1B several times until it flows into and arrives in the drying chamber 1B, the actual air volume and the wind pressure affecting the laundry are damped, 5), the flow of the wind pressure can not escape uniformly between the trays mounted on the loading car (5), and it is practically impossible to uniformly transmit the wind pressure to all the objects to be dried, Respectively.

As a result, the conventional drying apparatus has a problem that the wind pressure and the air volume which substantially affect the drying object are weak and the air flow is uneven and the air pressure can not be uniformly distributed. Therefore, the drying device requires a great amount of energy and drying time, There is an urgent need for improvement, for example, it can not but have certain limitations.

Accordingly, in the present invention, it is possible to uniformly distribute the dehumidified cold air or warm air to the stacking cart (the apparatus in which the drying object is placed in a multi-stage state with the drying object placed on the tray) in the drying room for agricultural and marine products, Of course, by reducing the loss of wind as much as possible and by distributing the dehumidified air volume further on the side of the bogie placed on the rear side, it is possible to increase the drying efficiency and the drying quality with the same energy and drying time. The present invention has been accomplished as a technical problem.

The upper dehumidifying air passage is divided into upper and lower horizontal partition plates 300 and the upper and lower horizontal partition plates 300 are connected to the upper and lower sides of the actual drying chamber 500, (700) in which a plurality of blowing fans (710) are disposed between an end of the rear part of the actual drying room (500) and a dehumidifying wind stagnation space (600) in the cold / hot air dehumidifying / drying device for agricultural and marine products Upper windshield windmill windshield 810 and lower windshield windshield windshield 820 are installed on the upper and lower sides of the inner space of the actual windshield 500 to prevent windshield wind, 500 is provided with a dehumidifying wind dispersing device 900 for extracting dehumidified wind from the front of the front drying room 500 and distributing the dehumidifying air by blowing the dehumidifying air to the drying drum 510 disposed at the front, And a drying infrared lamp 950 for drying.

The cold / warm air dehumidifying and drying device for agricultural and marine products of the present invention is capable of more clearly and uniformly delivering dehumidified air (dry or cold air from which water has been removed) to a loading car (laundry) in the agricultural and marine products drying chamber, Of course, the dispersion effect of the dehumidifying wind in the front of the drying room greatly contributes to the improvement of the drying efficiency, the improvement of the drying quality and the shortening of the drying time.
