Description

DETAILED DESCRIPTION OF THE INVENTION [0001] The present invention relates to a method for removing sawdust and rice bran.
A culture medium containing various nutrients as the main component
Of culture medium to be filled in a bag made of sticky film
The present invention relates to a bag filling device. [0002] 2. Description of the Prior Art Conventionally, sawdust or rice bran has been used as a main component.
Artificial cultivation of mushrooms using culture media containing nutrients
As a method, the culture medium is filled in a cultivation bottle and sterilization treatment is performed.
Enokitake and maitake in the filled cultivation bottle
After inoculating a fungus such as mushrooms, the mouth of the cultivation bottle
Cover with a cap and close to a predetermined temperature and humidity
Method of cultivating bacteria under conditions and industrially cultivating, or
The culture medium was filled into a plastic bag, and the filled
Fold the bag opening of the culture medium-filled packaging bag to the side of the bag,
Condition, and sterilize the culture medium together with the bag in this state.
Then, the inoculum is placed in the sterilized culture medium-filled packaging bag.
Seed and culture the bacteria under predetermined temperature and humidity conditions
Industrial cultivation methods and the like are being performed. [0003] In the former case, the mouth of the cultivation bottle
Cultivation of enoki mushrooms etc. according to caliber size
However, for shiitake mushrooms, etc.
It is not suitable for collecting mushrooms such as mushrooms.
Absent. Therefore, in artificial cultivation such as shiitake mushroom and nameko
The latter plastic packaging bag is used. In the former case, harvesting mushrooms
Later, the culture medium inside the cultivation bottle is scraped out and the cultivation
Use of cultivation bottles repeatedly by washing
Has the advantage of being able to
Is disposable in recent years, but the latter
Demand for packaging media-filled packaging bags is growing
It is. [0005] By the way, the operation of bagging the culture medium into a packaging bag
As a manual procedure, first press the bag mouth of the packaging bag.
Spread it and fill it with a certain amount of culture medium,
After compacting into a cylindrical shape using a jig,
Cultivate so that an inoculation hole is formed in the center via a stick, etc.
Packing and filling with nutrient base
are doing. [0006] However, the culture medium
Filling the packaging bag with culture medium
Filling work, compaction of the culture medium, or inoculation of inoculum
Labor such as drilling of inoculation holes for
Compression work by pressurization of the culture medium
The hardness of the press molding may vary,
If the culture medium is too soft during the opening of the bacterial
It may cause collapse. Therefore, in recent years, artificial mushrooms of this kind
As cultivation technology advances, handling of culture media and inoculation
A method for uniformly mass-producing mushrooms has been proposed.
It is proposed in, for example, Japanese Utility Model Laid-Open No. 6-41999.
Open the bag opening of the packaging bag that is closed on three sides
Type or special type of filling the culture medium into the bag
As described in Japanese Patent Application Laid-Open No. 8-25521,
Pull out the film from the rolled original film
Supply the culture medium while forming the film into a cylindrical bag.
A type that fills the inside of a cylindrical part, seals it, and carries it out
Each has been proposed. At this time, in the former case,
Take out the packaging bag, hold the opening of the bag, and then fill the culture medium.
Production efficiency is reduced due to the
There is a problem. [0009] In the latter case, the roll is wound into a roll.
While pulling out the film from the
Filling the culture medium into the cylindrical part while making the film into a cylindrical shape.
Fill and seal the culture medium by filling and sealing
And can be bagged while pressing
Production efficiencyToThere is a merit that it can be raised
Surface, because the packaging film does not have air permeability
If you close the breeder, breed the mushrooms that breathe
The opening of the bag is partially open due to inconvenience
Airflow between the inside and outside of the packaging bag.
It is necessary to take care that there is no invasion of various bacteria from outside
There is. [0010] Also, in consideration of this point,
For example, it is proposed in Japanese Patent Application Laid-Open No. 4-71422.
The film formed into a tubular shape is wound into a roll
At predetermined intervals along the width direction of the cylindrical film of
And the bag is formed,
A filter that ventilates inside and outside air while suppressing invasion of various bacteria into the bag
Are provided to form a roll-shaped tubular film.
Has formed. Pull the cylindrical film provided with this filter.
At the place sealed in the width direction of the film
By cutting the film along the cut line
The bags are taken out and filled with medium in the bags.
, So that bacteria can enter from outside through the filter
Can be suppressed, but roll-shaped cylindrical fill
Take out the bag while cutting the pieces one by one, and then
Mouth must be opened and medium must be filled, resulting in production efficiency
However, there remains a problem that is reduced. Therefore, the present invention solves the above-mentioned problems.
Guided withdrawal from roll material
While making the formed film into a tubular shape, the bag
Fill the inside with the culture medium, bag it and pull out the film.
Opening holes for ventilation of inside and outside air through the film
While opening at predetermined intervals, insert a filter into the opening
