New method for cultivation of Flammulina

At present, the conventional cultivation method of Flammulina velutipes widely used in various places, although it can receive 3 mushrooms a year, the bioconversion rate of culture materials is only up to 100%, and each growth period is up to 95 days, and only three cultivation cycles can be recycled in one year. And the mushroom handle of the third mushroom is short and thick, easy to open the umbrella cover, and the quality of the product is poor.

According to the growth characteristics of Flammulina velutipes, a new cultivation technology for disposable culture materials was prepared. The biotransformation rate was as high as 193%, the cultivation period was shortened by 40 days, and the number of Flammulina velutipes increased, the mushroom stem increased, and the economic benefit was increased by about 80%. The technical points are as follows:

Self-made culture material: cotton husk 84%, wheat bran 14%, gypsum 1%, potassium dihydrogen phosphate 0.2%, magnesium sulfate 0.25%, carbendazim 0.55%, mix well, mix with water: 1:1.3 , Serve the culture material.

Packing disinfection The culture material is placed in a wide-mouth bottle bag. When filling, it is necessary to make the elasticity moderate to effectively avoid the phenomenon of the bottle and bag around the bottle. After filling, the bottle and bag mouth are sealed, placed in a normal temperature pot for disinfection, and cooked at a high temperature of 100 ° C for 8 to 10 hours.

After moderate temperature cultivation, after thoroughly cooling, in the inoculation room or in the inoculation box, under the flame of alcohol lamp, use the inoculating shovel to excavate the mushroom seed block from the strain bottle into the cultivation bottle and bag, and then put it into the culture room for hyphae. to cultivate. The temperature of the culture chamber must be controlled at 22 ° C ~ 26 ° C, it is strictly prohibited to pull down the long culture period to avoid the hyphae not full, the mushroom will be produced, affecting the yield and quality.

After careful management of the hyphae, you should move into the mushroom field in time, open the bottle and bag for sputum, and stimulate the mushroom. When the buds are formed, it is necessary to carry out regeneration management to promote the density of the mushroom buds, and then bagging or covering the newspapers to form a high-concentration carbon dioxide microclimate in the bottles and bags to facilitate the growth of Flammulina velutipes.

When the mushroom grows to a height of 4 to 5 cm, special attention should be paid to water management. The humidity of the cultivation site should be maintained at 80% to 90%, the temperature should be maintained at 8 °C to 14 °C, and the curtains or black plastic cloth should be used to cover the cultivation site. The light intensity can be blurred with normal vision to see the 5th Chinese character. When the mushroom grows to a height of 15 to 20 cm, it can be harvested.

Disposable Breathing Filter

Why use Heat Moisture Exchanger Filters (HMEF)
• HMEF is passive humidification with bacterial/viral filtration efficiency.
Gases emerging from Anesthesia machine are dry and room temperature (cold)
• Tracheal intubation or use of laryngeal mask airway bypasses upper airway modifying pattern
of heat and moisture exchange, lungs need 37° & 100% relative humidity.
• Cilia can stop beating with impaired mucocilliary function includes sputum retention &
increased risk of infection .

• Warmed humidified air is better than cold, dry gases even in short cases.

When a patient`s trachea is intubated or a supraglottic airway device is placed in situ, the normal warming, humidifying and filtering functions of the upper airways are bypassed. Hence, gas delivered to the patient needs to be artificially conditioned to replace these lost functions Heat and moisture exchangers (HMEs) are intended to conserve a portion of the patient`s exhaled heat and moisture, and condition inspired gas by warming and humidifying it. Breathing system filters are intended to reduce the transmission of microbes and other particulate matter in breathing systems.

Devices that contain both filters and HME are called Heat Moisture Exchanger Filters (HMEFs). It is not ideal to distinguish these two common filters with "static" and "folds", because these two types of filters rely on electrostatic charge to a certain extent to keep the particles in the filter material, two types All materials can be folded. The main difference between the two types is the density of the fibers. For "electrostatic" filter materials, the density of the fibers is relatively low, and the electrostatic charge (fiber or triboelectric charge) on the fibers is high. For "pleated" filters, the density of the fibers is high: this leads to increased resistance to gas flow; the pleated material increases the surface area, thereby reducing the resistance. This type of filter is also called "hydrophobic" (because the surface of the filter material repels water) or "mechanical". In this review, the terms "electrostatic" and "pleat" will be used to distinguish these two types of filters.

Used in anesthesia and respiratory system, our B/V Filter is designed for the
protection of the patient, hospital personnel and the equipment from
potential microbial contamination.
Features:
Lightweight reduces torque on tracheal connection.
ISO connectors allow for safe and secure connections.
Gas sampling port with cap for easy, safe monitoring of expired gases.
