Abstract
A uniform control method of environmental elements of a fungus culturing workshop during edible fungus industrial cultivation belongs to edible fungus production technology. The invention aims to solve the following problems: as the fungus flasks are in different positions in the existing fungus culturing workshops and the edible fungi in the fungus flasks with unsuited temperature, humidity and CO2 contents grow slowly, mixed fungi are more probable to emerge and the mixed fungi contamination rate is 1-3% on average; and the fungus culturing effects of the fungus flasks in the same workshop are hard to control uniformly. The invention is characterized in that an air inlet fan is arranged on the upper part at one side in the workshop, an internal cycle refrigerating fan is arranged on the upper part at the other side and an exhaust fan is arranged in the middle; sensors for monitoring the environmental elements of the workshop are arranged in the form of space lattice; and opening and shutting down and the running speeds of the air inlet fan and the exhaust fan are controlled by a programmable logic controller (PLC) according to the information obtained by the sensors for monitoring the environmental elements. Test run shows that the invention has the following beneficial effects: the mixed fungi contamination rate is substantially reduced to 0.2-0.3%; and the fungus age difference caused by different positions is reduced from 8-10d in the prior art to 1-2d.
Description
Technical field
The invention belongs to the Edible Fungi technology, bacteria workshop condition key element uniform control method in particularly a kind of edible fungus industrial cultivation.
Background technology
In the bacteria flow process in the existing edible fungus industrial cultivation, bacteria workshop condition key element---in the process that temperature, humidity, carbon dioxide content are controlled, occur because the residing position of bacterium bottle difference, difference must appear in residing environmental key-element, some edible fungi growths that are in the relatively more suitable bacterium bottle of temperature, humidity, carbon dioxide content are good, and some edible fungi growths that are in temperature, humidity, the more unaccommodated bacterium bottle of carbon dioxide content are slow, and the possibility that assorted bacterium occurs greatly increases.Thereby the phenomenon that causes occurring living contaminants on the one hand is difficult to control, and the living contaminants rate is on average at 1-3%; On the other hand, edible fungi growth in same batch the bacterium bottle is uneven, the bacterium order that is in temperature, humidity, the more unaccommodated bacterium bottle of carbon dioxide content makes slow 8-10 days than the bacterium in all the other bacterium bottles in the same workshop, must influence the raising of single damp biological transformation ratio.This shows, design that bacteria workshop condition key element uniform control method is necessary in a kind of kind edible fungus industrial cultivation of having controlled microbial contamination and balanced control bacteria effect preferably.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, design bacteria workshop condition key element uniform control method in a kind of kind edible fungus industrial cultivation of having controlled microbial contamination and balanced control bacteria effect preferably.
The object of the present invention is achieved like this:
Bacteria workshop condition key element uniform control method in a kind of edible fungus industrial cultivation is placed bacteria bacterium bottle group at bottom, workshop sky be 0.5 meter away from surroundings wall more than, it is characterized in that
--a upper lateral part is provided with the air intake machine in the workshop, and circularly cooling blower fan, middle part were provided with air exhauster in opposite side top was provided with in the workshop;
--it is workshop length 1/2nd, the downward exhaust duct of exhaust outlet that the air intake machine disposes length;
--exhaust outlet sensing air intake machine one side of interior circularly cooling blower fan, air inlet are positioned at air exhauster one middle side part;
--the long degree of having of air exhauster configuration is the exhaust column that workshop length 1/2nd, air inlet make progress;
--be connected with the tube connector that is " S " type between air exhauster and the exhaust column;
--by the space lattice mode sensor that the workshop condition key element is monitored is set in the space that exhaust duct is following in the workshop, exhaust column is above;
--the unlatching of air intake machine, air exhauster with close down, the speed of service controlled it according to the environmental key-element information that workshop condition key element monitoring sensor obtains by PLC (English full name Programmable LogicController, Chinese full name is a programmable logic controller (PLC)) automatic control system.
Purpose of the present invention can also take following further measure to realize:
The unlatching of air intake machine, air exhauster with close down and will carry out synchronously, guarantee that simultaneously the air quantity of air intake machine is greater than the air quantity of air exhauster, can guarantee the malleation of the maintenance of the gas the workshop in the opening process like this greater than normal atmosphere (An).
Be connected with the tube connector that is " S " type between air exhauster and the exhaust column, suction opeing below near mill floor, air outlet up outside the workshop ground prevent like this when blower fan stops more than 1.5 meters that ambient atmos flows backwards from air outlet and enters the workshop.
Circularly cooling blower fan in opposite side top is provided with in the workshop, and exhaust outlet points to air intake machine one side, air inlet is positioned at air exhauster one middle side part can make temperature in the workshop, humidity, carbon dioxide content uniformity more effectively.
The flow direction unanimity of the wind that all devices in bacteria workshop brings is guaranteed in above further measure: from top to bottom, and from entering out.
The bacteria flow process of the invention process in Asparagus, Pleurotus eryngii industrial cultivation shown following beneficial effect:
1, controls living contaminants preferably, reduced the living contaminants rate significantly.Owing to adopt the PLC automatic control system to the workshop condition key element---temperature, humidity, carbon dioxide content are evenly controlled, because of the residing position of bacterium bottle difference, the environmental key-element difference greatly reduces, edible fungi growth in all bacterium bottles is good, thereby the possibility that assorted bacterium occurs greatly reduces, and the living contaminants rate is reduced to 0.2-0.3% significantly by 1-3%.
2, the edible fungi growth in same batch the bacterium bottle is evenly neat, and the edible mushroom bacteria effect in the same workshop in the bacterium bottle also is able to balanced control, has improved single damp biological transformation ratio.Because adopting the PLC automatic control system controls the flow process environment, to bacteria flow process workshop condition key element---temperature, humidity, carbon dioxide content are evenly controlled, produce the bacteria flow process growth and development environment that the bacterium bottle obtains the best thereby make, mycelial growth physically well develops, the bacterium that residing position difference causes makes difference 8-10 days by prior art, be reduced into 1-2 days, must have improved single damp biological transformation ratio effectively.
Description of drawings
Fig. 1 is the schematic diagram of air intake machine, interior circularly cooling blower fan, air exhauster setting and exhaust duct, exhaust column configuration.
Embodiment
Below in conjunction with accompanying drawing implementation detail of the present invention is described as follows:
