Abstract
The invention relates to the technical field of aerobic microbe culture, in particular to a filter-medium-free sterile ventilated culture box, which mainly comprises a box cover and a box body. Spiral ribs or spiral grooves are arranged at junctions of the box cover and the box body, so as to form a spiral ventilation passage at the junctions of the box cover and the box body. By using the filter-medium-free sterile ventilated culture box, microbes (sundry bacteria) in air which enters the box can be adsorbed on the surrounding wall of the wet spiral ventilation passage, the effect of obtaining sterile air without using any filter medium is realized, the effect of filtering the air is reached and a sterile environment is formed in the box. The filter-medium-free sterile ventilated culture box not only has the advantages of simple structure, low production cost and high safety and reliability, but also has the advantage of extremely wide application scope, and is quite suitable for factory production.
Description
Technical field
The present invention relates to aerobic microorganism culture technique field, what relate in particular to that a kind of edible fungus culturing, plant tissue culture, mushroom strain cultivation use cultivates box without the aseptic ventilation of filter medium.
Background technology
Since Dutch biologist's Leeuwenhoek in 1675 is found microorganism with microscope, scientists need to be cultivated pure single microniological proudcts for difference, the for example cultivation of aerobic microorganism, must be at first with other microorganism of occurring in nature, namely miscellaneous bacteria is kept apart, but can not affect entering of air, and create the filtrated air environment for the aerobic microbial growth, could realize this purpose.Therefore, people go through constantly research in hundred years, and have developed " filtrated air filter medium " and the corresponding filter plant of various materials according to different needs, and so as to the microorganism with air, namely miscellaneous bacteria filters out, and obtains filtrated air.Yet no matter how " the sterile air filter medium " of precise high-efficiency in the situation of natural permeable, all can have the penetrating amount of air that affects in various degree, and can't satisfy the mushroom cultivated to the needs of different growth and development stages; As strengthen the filter area of filter medium, often the size of receptor limits again, moreover has increased production cost again.More nerve-wrackingly be, in case filter medium is because being subjected to certain factor (as make moist, damaged, blockage of the micro orifice and medium are aging etc.) just can cause living contaminants when losing filter effect, being difficult to realize the stability of whole incubation, is that people are exploring the difficult problem how to solve always.
Summary of the invention
The objective of the invention is the defective for above-mentioned prior art, what a kind of simple in structure, stable height of culture environment and applied range were provided cultivates box without the aseptic ventilation of filter medium.
The present invention mainly is comprised of lid and box body, and the junction that solves technical scheme that its technical problem adopts and be lid and box body arranges spiral ridge or helical groove, forms spiral venting channels with the junction at lid and box body.
Above-mentioned spiral ridge or helical groove both can be arranged on the lid of lid and box body joint, also can be arranged on the box body of lid and box body joint.
The thickness of above-mentioned spiral ridge or the degree of depth of helical groove are 2～5 millimeters.
The napex of above-mentioned box body arranges flange, between flange and the box body outer surface some reinforcements is set.
The flange at above-mentioned box body top is outward-dipping.
Of the present inventionly cultivate box in use without the aseptic ventilation of filter medium, air spirals by spiral venting channels and enters in the box, and airborne microorganism, namely miscellaneous bacteria is in the process that enters of spiraling, constantly with the interior Zhou Sibi collision of moist spiral venting channels, airborne miscellaneous bacteria absorption is trapped on the interior Zhou Sibi of moist spiral venting channels, thereby has realized having obtained without any filter medium the effect of filtrated air.
The invention has the beneficial effects as follows:
1, simple in structure, production cost is low.
2, culture environment stability is high in the box.The length of spiral ridge or helical groove, the number of turns of spiral and the thickness of fin or groove can be set according to the size of container, thereby form the spiral venting channels of different size, container is larger, and venting channels is longer, projection and the recess dimensions of fin or groove are larger, otherwise less.
3, be fit to mechanization production.Be fit to the mechanization production pattern, improve work efficiency 3-5 doubly than existing production model, output is high, can realize the large-scale production of edible fungus culturing.
Generally speaking, the present invention not only has simple in structure, and production cost is low, and is safe and reliable, and application is very extensive; And quite suitable batch production is used.With regard to the edible mushroom industry, can expect that popularizing and using of this invention will cause a new revolution.
