Abstract

The utility model relates to a liquid seed-producing and fermentation device for edible fungi, which is composed of a jacket outlet connection, a jacket electric heater, a jacket inlet connection, a pressure tap, an exhaust port, a side-view mirror, a temperature measurement port connection, a tubular electric heating element, a D0 sensor and a PH sensor. The utility model is characterized in that an airflow mixing system is arranged and is composed of a ventilating pipeline with a one-way valve and a circular ring pipe of which bottom outer side is provided with small holes, wherein the one-way valve is arranged at the inlet position of the ventilating pipeline; the inlet of the ventilating pipeline is positioned on the upper part of the cylindrical surface of a tank body; the ventilating pipeline is connected with the circular ring pipe arranged on the bottom of a fermentation tank, wherein the outer side on the bottom of the circular ring pipe is provided with the small holes. The gas enter from the ventilating pipeline with the one-way valve and is led to the in-tank circular ring pipe of which the bottom outer side is provided with the small holes. When the gas flow out from the small holes on the outer side on the bottom of the circular ring pipe, a similar empty space is formed in the middle of the circular ring pipe. The liquid in the tank flows upward from the circumference of the wall in the tank and the fluid of the middle region of the tank flows downward, thereby, the uniform stir is realized.

Description

Edible fungus liquid production of hybrid seeds fermentation unit

Technical field

The present invention relates to fermentation equipment, refer in particular to a kind of edible fungus liquid production of hybrid seeds fermentation unit.

Background technology

In recent years, the employing deep layer culture process prepares edible fungi liquid strain and is used for production becomes the research and development focus.Liquid spawn is applied in edible fungus industrial, anniversaryization, large-scale production, has unusual effect for shorten to send out the bacterium time, reduce production costs, improve yield and quality, inoculation is convenient etc.

The edible mushrooms dedicated liquid fermentor tank of exploitation mostly adopts the mechanical stirring system at present, and accurately control degree is not high, and mycelium easily is damaged, and is difficult to realize that the stdn liquid spawn produces; Because it is different that its fermentation parameter of different bacterial classification requires, and domestic present fermentation equipment configuration differs, and need find out the corresponding production technique of selected bacterial classification and equipment by conscientious test.

Summary of the invention

In order to overcome the destruction that mycelium in the existing liquid production of hybrid seeds fermentation unit causes because of mechanical stirring and the situation of bacterial classification vulnerable to pollution, the present invention has done improvement to liquid fermenting equipment, utilize aerodynamics, automatic control technology, fluid mechanics principle to develop a kind of novel fermentation jar, control in when fermentation by gas flow in to jar reaches to high oxygen supply of fermented liquid and the purpose that evenly stirs, replaced the mechanical stirring system, simple in structure, easy to operate, do not hinder mycelia, avoid living contaminants.

A kind of edible fungus liquid production of hybrid seeds fermentation unit, by the Jacket outlet joint, the chuck electric heater, the chuck inlet union, pressure tapping, venting port, side-view mirror, the temperature-measuring port joint, tubular electrical heating element, the DO transmitter, the pH transmitter is formed, it is characterized in that: be provided with the air-flow stirring system, it is by the breather line that has check valve, the narrow meshed ring tube of bottom outside is formed, check valve is installed in the breather line ingress, the breather line inlet is positioned at the top of tank body cylinder, ventpipe with place fermentor tank at the bottom of and the narrow meshed ring tube of bottom outside link to each other, gas enters from the breather line that has check valve, pass to jar narrow meshed ring tube in the inner bottom part outside, when ring tube bottom outside aperture flows out, in the similar vacuum zone of ring tube intermediate formation, pot liquid upwards flows around the jar inwall, jar region intermediate fluid flows downward, and realizes evenly stirring.

Native system is different from traditional internal recycle, outer circulation airlift fermentor, and the blade diameter length ratio of tank body is identical with the mechanical agitator tank class, therefore can be used for the technological transformation of traditional mechanical agitator tank, and 1. gas bubbles is more little, gives jar interior thalline oxygen-supplying amount high more; 2. it is more abundant to mix stirring, does not damage mycelia, makes fermentation period shorten greatly, enhances productivity; 3. control service life and stop service life more adjustable continuously in 1: 1～10: 1 intervals than (interval type air feed), make mycelium that the chance of " not giving birth to and bringing up breath " be arranged, growth is faster, better.After tested: (1) dissolved oxygen improves about 30%, and (2) energy consumption reduces about 30%, and (3) to the mycelia not damaged, (4) have reduced the living contaminants factor; (5) fermentation time shortens about 30%; (6) bacterial classification concentration increases about 25%.

Embodiment

This fermentor tank adopts the manufacturing of high-quality stainless material, transfers edible mushrooms, the production of hybrid seeds of medicinal fungus liquid to and designs, and has characteristics such as simple in structure, easy to operate, is the indispensable equipment of development mushroom industry.

As shown in Figure 1, breather line (3) is positioned at the top of tank body cylinder, break-make by check valve (1) control breather line (3), breather line (3) links to each other with the bottom narrow meshed roundlet endless tube in the outside (5), ring tube (5) is at the jar inner bottom part, chuck thermostat(t)ed water inlet union (4) is in jar external jacket bottom, chuck thermostat(t)ed water outlet connection (2) is on jar external jacket top, photoscope (8) at the middle part of tank body on the upper side, temperature-measuring port joint (9) is about 1/3 place, bottom, tank body right side, the air outlet (6) of band valve is at the tank deck center, and pressure tapping (7) is on the tank deck right side.

Gas feeds from the breather line (3) that check valve (1) is arranged, and by the aperture outflow in the outside, ring tube [5] bottom, the gas circulation of ventilating by interval type reaches the fermented liquid oxygen supply, evenly stirs, and fermented liquid is fully fermented, and circulation as shown in phantom in Figure 1.Should in time see through side-view mirror (8) during fermentation and observe and carry out record, comprise the smell of temperature (temperature-measuring port joint (9) is located thermometer), pressure (tensimeter is located in pressure tapping (7)), airshed, discharge gas (air outlet (6)) etc.As running into power failure, vent valve is closed automatically or is manually closed and keeps being in the jar barotropic state.Restart behind the incoming call, and open vent valve and continue to cultivate.In the culturing process, aseptic technique sampling analysis is at any time treated can inoculate after the bacterium ball density suitable (observing from visor).
