Abstract

PROBLEM TO BE SOLVED: To provide an energy saving and lower cost culture device capable of cooling a mushroom bed in a short time. SOLUTION: In this culture device, water in an ice storage tank 2 is cooled by a heat pump 3, the cooled water is returned to the ice storage tank 2 to cool the water in the ice storage tank 2, and when the water in the ice storage tank 2 is fed to the side of a mushroom bed 4 by a pump 8 through a tube 6, the mushroom bed 4 is cooled. the water having cooled the mushroom bed 4 is circulated again to the ice storage tank 2 through a tube 7.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cultivation apparatus for use in an ice storage type germ bed cooling system.

[0002]

2. Description of the Related Art For example, when growing and cultivating fungi such as mushrooms, it is necessary to keep the temperature inside the cultivation chamber at around 16 ° C. Conventionally, in order to maintain the temperature, the entire cultivation room is generally cooled by a heat storage type or a heat pump air conditioner for cultivating the bacterial bed.

[0003]

However, in the case of such a system for cooling the entire atmosphere inside the cultivation chamber, it takes time to keep the temperature of the bacterial bed at around 16 ° C. and energy efficiency is reduced. There is a problem of bad.

[0004]

In order to solve such a conventional problem, the cultivation apparatus according to the first aspect of the present invention comprises a heat pump and an ice heat storage tank so as to cool water in the ice heat storage tank. And the ice heat storage tank and the bacterial bed are connected by a cooling water circulation path.

The cooling water circulation path includes a tube for supplying cooling water from the ice heat storage tank to the bacteria bed, a tube for returning cooling water from the bacteria bed to the ice storage tank, and a cooling water circulation pump for pumping the cooling water in the tube. Is formed of, for example, a vinyl hose, a metal tube, a PVC pipe, or the like, and may pass through a portion near the surface such as the bottom, side, or upper portion of the bacterial bed, or may pass through the inside of the bacterial bed. Furthermore, in order to cool the bacterial bed, a fin or the like having a plate-like, rod-like, or needle-like projection may be brought into contact with the bacterial bed, and the fin may be cooled by passing through the tube. Alternatively, the tube may be cooled by bringing the tube into contact with a metal fungus bed cultivation shelf.

FIG. 1 is a schematic diagram of a cultivation apparatus according to an embodiment of the present invention. In this embodiment, the cultivation apparatus is for cultivating a mushroom bed, but may be a plant.

The cultivation apparatus 1 connects the heat pump 3 and the ice heat storage tank 2 so that the water in the ice heat storage tank 2 can be cooled, and the cooling water circulation path 5 connects between the ice heat storage tank 2 and the bacteria bed 4. Connected. The germ bed 4 is a cultivation shelf 1 installed inside a cultivation room 9.
0.

The cooling water circulation path 5 includes a tube 6 for supplying cooling water from the ice heat storage tank 2 to the bacteria bed 4, a tube 7 for returning cooling water from the bacteria bed 4 to the ice storage tank 2, and a cooling water in the tube 6. And a chilled water circulating pump 8 for pressure feeding. The tubes 6 and 7 are formed of, for example, a vinyl hose, but may be formed of a metal tube, a PVC tube, or the like. Also,
The tube 6 may pass through a site near the surface such as the bottom, side, or upper portion of the bacterial bed 4, or may pass through the inside of the bacterial bed. Further, in order to cool the bacterial bed 4, a cooling fin having a plate-like, rod-like, or needle-like projection is brought into contact with the bacterial bed,
The cooling may be performed by bringing the tube into contact with the cooling fins. Alternatively, place the tube in a metal cultivation rack 1
Alternatively, cooling may be performed by contacting with zero.

The ice heat storage tank 2 is a heat insulating container capable of storing cold water and ice, and supplies cooling water to a cooling water supply tube 6 extending inside the cultivation chamber 9,
Cooling water circulates and flows in from a tube 7 extending from the inside bacterial bed 4 to the outside of the cultivation room 9.

The heat pump 3 is for removing heat from the water in the ice heat storage tank 2 and supplying the cooled water to the ice heat storage tank 2 again. A commercially available heat pump is used. Alternatively, a controller for storing heat as ice or cold water may be provided.

According to the cultivation apparatus 1, the heat pump 3
To cool the water in the ice heat storage tank 2, return the cooled water to the ice heat storage tank 2, cool the water in the ice heat storage tank 2, and further cool the water in the ice heat storage tank 2.
Is sent to the bacterial bed 4 side through the tube 6 by the pump 8, the bacterial bed 4 is cooled. The water that has cooled the bacterial bed 4 circulates again through the tube 7 to the ice heat storage tank 2.

At this time, since the bacterial bed 4 is directly cooled, it is not necessary to cool the entire atmosphere inside the cultivation room 9 and the cooling time is short. According to the experimental example, for example, the temperature of the
In this case, the air temperature inside the cultivation room 9 may be as high as 19 ° C. and 3 ° C., the heat radiation loss of the cultivation room 9 can be reduced by about 25%, and there is an advantage of energy saving. By using, the running cost can be further reduced. Further, since the tubes 6, 7 and the ice heat storage tank 2, the cold water circulation pump 8, and the heat pump 3 are commercially available products, the cost is low.

[0013]

According to the cultivation apparatus of the present invention, the water in the ice storage tank cooled by the heat pump is supplied to the bacteria bed via the cooling water circulation path, and the water cooled in the bacteria bed is again stored in the ice storage. By circulating in the tank, the bacterial bed can be kept at a low temperature, and there is no need to cool the entire atmosphere in the cultivation room, and low cost and energy saving can be promoted.
