Description

STERILIZING AND FERMENTING SYSTEM OF CULTIVATION MEDIUM FOR MUSHROOM

The present invention relates to a sterilization fermentation system for cultivating mushrooms, and more particularly, to sterilize mushroom medium first under normal pressure, and to inoculate mushroom seedlings by amplifying aerobic bacteria necessary for mushroom seed culture on mushroom medium. It relates to a sterilization fermentation system of mushroom medium.

In general, mushrooms are classified as a microorganism belonging to Basidiomycetes, which are mostly edible, except for toxic ones. These mushrooms are high protein foods that can replace meat and have been used by monks since ancient times. It is recognized as a beneficial natural health food to prevent and is expected to be our main source of agricultural products.

In particular, the effects of anticancer and antivirus caused by glucan derivatives, which are polysaccharides contained in mushrooms, have been reported and are widely recognized as health foods. (Study on anticancer component of Korean basidiomycetes, including Kim Byeong-kak. The Korean Journal of Mycology, 8: 107 (1980); Kang, Chang-Jin, et al., Studies on the Anticancer Components of Korean Basidiomycetes, Mycelial Culture and Anticancer Components of Bulchocho, Korean Journal of Chemistry, 14: 101 (1981); Miyazaki, T., Nishijima, M , Studies on fungal polysaccharides (XXVII), Structural examination of a water-soluble, antitumor polysaccharides.Chem. Pharm. Bull. 29: 3611 (1981)).

As a cultivation method of such mushrooms, depending on the type, they have been cultivated by inoculating spawns by drilling holes in solid wood such as oak, zelkova, oak and oak (Japanese Patent Application No. 61-268109, 62-186726, etc.), In recent years, the method of cultivating mushrooms has been improved, and the method of cultivating mushrooms has been improved, and the method of growing sawdust or waste cotton as a medium for growing bottles, boxes, bags, etc. -40169, 48-39540, etc.) have been developed.

However, the method using the medium as described above is difficult to cultivate mushrooms successfully because of problems such as breathability and nutrient supply of the medium itself. The contaminating bacteria will survive and multiply and eliminate the factors that hinder the growth environment of the mushrooms.

As a technology to solve this problem, sterilization under high pressure (1.1 ~ 1.2㎏ / ㎠), high temperature (110 ~ 121 ℃) in a sealed environment recently, and then inoculated mushroom spawn in a sterile state completely sealed sterilization Apparatus has been developed for performing a method of blocking automatically (Patent Publication No. 95-8868).

However, since the prior art (Patent Publication No. 95-8868) inoculates the mushroom spawn in a sterile state by completely sterilizing the mushroom medium, the success rate of the mushroom cultivation is very high, but the high-pressure sterilizer is very expensive for use in general farms. In addition, if there is equipment used in addition to that, there is a problem that it is enormously expensive to bear in general farms. In addition, the conventional high-temperature autoclave requires the expertise and technology to work in a completely sterile state, it is very difficult for ordinary farmers to actually use this technology. That is, even though the success rate of mushroom cultivation is high, it is difficult to spread to general farms.

Therefore, the present invention is to provide a mushroom medium sterilization and fermentation system that is easy to actually use the mushroom cultivation method in a common farm, and can significantly increase the success probability of mushroom cultivation.

In addition, the present invention is to provide a mushroom medium sterilization fermentation system for fermenting aerobic bacteria sterilization and aerobic bacteria that can be produced at a cost practically available to the general farmhouse compared to the mushroom medium sterilization system of high temperature and high pressure have.

In addition, the present invention is to provide a sterilization and fermentation system of the mushroom medium that can be sterilized by fermentation of the medium easily if the technical level used in the thermal insulation cover house used in the conventional farmhouse, the technical problem. .

Sterilization and fermentation system of mushroom medium, characterized in that consisting of a cooling fan 19 mounted for.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

In recent years, the culture medium of mushrooms is using a sawdust, bran, sugar cane, bananas, lung noodles and the like or a mixture of two or more kinds. In this case, in the process of making the medium suitable for the growth of the mushroom spawn, the bad bacteria that fatally adversely affect the culture of the mushroom spawn in the medium are also multiplied, thereby causing the mushroom cultivation to fail. Therefore, sterilizing the mushroom culture medium is an essential procedure, and mushroom growers have conducted a lot of research for this purpose. One such method is to inoculate the mushroom spawn in a sterile state by completely sterilizing the mushroom broth, but the place for inoculating the mushroom spawn should be made quickly at the sterilization site of the broth. Even if it is exposed, there is a fear of failure due to air pollution, so there are many difficulties in using it in general farms.

Therefore, in the present invention, sterilization of the immune system against bacteria that adversely affects mushroom cultivation even when the medium is exposed to air by proliferating aerobic bacteria in the medium after the sterilization process of the medium, rather than using such a complete sterilization method. Adopt fermentation, seeding and inoculating mushroom seedlings (see State of the art Mushroom cultivation and management, Seongsan, 1996).

In order to sterilize mushroom culture medium and grow aerobic bacteria in mushroom culture, sterilize the medium for 12 hours at 60-65 ° C. in literature, and then sterilize and ferment the medium for 3 days at 50-55 ° C. to grow aerobic bacteria.

A schematic explanatory drawing of the mushroom medium sterilization and fermentation system of the present invention to meet these conditions is shown in FIGS.

1 to 5 is a schematic diagram of the sterilization and fermentation system of the mushroom medium according to the present invention.

1 to 5, the present invention is a mushroom medium sterilization and fermentation system (1), the wall surface is made of a container-type container (2) consisting of an insulating urethane panel, the container-type container (2) is A chamber 4 for stacking the mushroom medium box 12 in front of the container in a multi-layered manner to perform sterilization and fermentation of the mushroom medium and a partition wall 5 at the rear of the container 2 are formed by an insulating panel. It consists of a boiler room 7 equipped with a boiler 6 which supplies hot steam and heat to the fermentation chamber 4.

The chamber 4 has a copper pipe steam pipe 9 connected to the boiler 6 to the bottom surface of the chamber for heating the chamber 4 by steam steam heated from the boiler 6 in the boiler room 7. Excreted in '으로' shape. The copper pipe steam pipe 9 has a structure in which steam nozzles are provided at intervals of about 20 cm so that hot steam is uniformly ejected into the chamber 4.

In addition, the chamber (4) was used to increase the temperature of the chamber by disposing the boiler communication (10) in the 'Ω' shape to the upper end of the chamber to recycle the waste heat generated from the boiler (6), the outlet of this communication 20 is installed at one upper end of the front of the chamber to exhaust the boiler waste and waste heat to the outside.

According to the system of the present invention, the temperature of the medium in the chamber 4 for sterilizing and fermenting the mushroom medium can be maintained at a temperature of about 60 to 65 ° C. and a medium humidity of 70 to 75% within a short time. Subsequently, after the first sterilization of the medium by maintaining the temperature at about 12 hours, in order to proliferate and ferment aerobic bacteria in the medium, the temperature of the medium should be adjusted to 50 to 55 ° C. The damper exhaust port 15 provided on one side of the chamber 4 discharges hot steam to the outside, and at the same time, the chamber 4 and the boiler chamber 7 at one upper end of the partition wall 5 of the chamber 4 The cooling circulation fan 19 mounted to adjust the temperature is operated to circulate the air in the chamber 4. In this way, after adjusting the temperature of the chamber 4 to 50-55 degreeC, the temperature in the said chamber is suitably maintained using the boiler 6. As shown in FIG. At this time, the means for maintaining the temperature is controlled using an automatic temperature system (not shown). At this time, the reason for operating the damper exhaust port 15 of the upper end of the container 2 and the cooling circulation fan 19 of the upper end of the partition wall 5 is that the aerobic bacteria necessary for cultivating the mushroom spawn need fresh air (containing oxygen). In the case of non-air (air containing a large amount of CO ₂ gas), aerobic bacteria do not grow in the sterilized medium, and anaerobic bacteria, which have a fatal effect on mushroom cultivation, grow in the medium. In other words, the medium containing anaerobic bacteria cannot grow mushroom seeds, causing mushroom cultivation to fail.

In addition, a removable platelet pallet 11 is laid on the entire bottom surface 8 of the chamber 4 so that an operator enters through the front door 16 installed in the front of the chamber 4 and the chamber 4 When working inside, it was possible to work safely without damaging the copper pipe steam pipe (9) laid on the bottom surface (8). The platelet-type pallet 11 used a bed plate used in rice farming of the general farm. In addition, the front door 16 is attached to the contact surface of the door 16, the silicon barking is used to install the overlap locking device to increase the sealability of the chamber (4).

In addition, the inner chamber 4 is provided with a discharge box shelf 13 for stacking the mushroom medium box 12 on the pallet 11 in a multi-layered space, thereby stacking a large amount of mushroom medium. Can be sterilized and fermented. In addition, the front bottom surface 8 of the chamber 4 is provided with a drain 4, when the air in the high temperature and high humidity chamber 4 condenses and flows to the bottom surface 8 of the chamber, naturally It is discharged to keep the inside of the chamber (4) clean, without any additional effort even when cleaning the chamber (4), it was possible to simply discharge the water generated in the chamber to the outside.

In order to explain this in more detail, a cross-sectional explanatory diagram of the bottom surface of the dotted line portion 'A' of FIG. 1 is shown in FIG. 7. In FIG. 7, the bottom surface 8 of the chamber is composed of a heat-insulating urethane panel, and a copper pipe steam pipe 9 is installed thereon, on which a base plate pallet 11 is placed. The discharge box shelf on which the discharge box 12 is placed is mounted on the bottom surface of the chamber 4 configured as described above.

In addition, the side of the chamber 4 is equipped with a discharging door 17, which is convenient for transporting the medium sterilized and aerobic bacteria fermented to the outside.

The boiler room 7 behind the vessel 2 is provided with a rear door 18 through which an operator can enter and a water tank (not shown) capable of continuously supplying water to the boiler 6.

In addition, the container-type container 2 of the mushroom medium sterilization and fermentation system 1 according to the present invention, the traction ring 21 in front of the container-type container 2, as shown in FIG. ), The transport wheel 22 is integrally or detachably installed at the rear lower end of the container. Reference numeral 23 is a folding staircase.

The final medium produced in the mushroom medium sterilization and fermentation system according to the present invention is capable of inoculating mushroom spawn directly in the system, or by inoculating the mushroom spawn by moving to a thermal cover house used in a general farmhouse. It is grown.

Hereinafter, the present invention will be described as follows.

Example

Using the sterilization and fermentation system of the mushroom medium according to the present invention, the mushroom medium having the lung surface as a substrate was sterilized for 12 hours at 65 ° C (humidity 75%), and then aerobic bacteria was removed for 3 days at 50 ° C (humidity 75%). Proliferation produced 10 medium at a time. This was repeated 10 times to produce mushroom medium of 10 groups (10 medium per group). Subsequently, seedlings were inoculated with oyster mushrooms in the medium of each group to cultivate the mushrooms in a house for thermal cover used in general farms. As a result, 9 groups of 10 mediums successfully grown mushrooms and obtained 90% success rate.

This result was evaluated as a great efficiency compared to the 60% success rate when inoculating and cultivating the mushroom culture medium in a thermal cover house used in ordinary farms.

In addition, the conventional high-temperature high-pressure mushroom medium sterilization apparatus has a success rate of 90% or more, but the apparatus according to the present invention is very inexpensive in terms of manufacturing and selling price of the sterilizing apparatus (can be produced and sold at a quarter price). There is a great efficiency.

The sterilization and fermentation system of the mushroom medium according to the present invention is easy to actually use the mushroom cultivation method in a general farmhouse, and has an effect of significantly increasing the success probability of mushroom cultivation.

In addition, the sterilization and fermentation system of the mushroom medium according to the present invention has an effect that can be produced at a cost practically available in a general farm compared to the mushroom medium sterilization system of high temperature and high pressure.
