Description

A kind of air lift type strain fermentation device

Technical field:

The invention belongs to fermentation equipment technical field, relate to a kind of air lift type strain fermentation device, particularly a kind of strain fermentation of inoculation fermentation under high sterility condition is filled with.

Background technology:

Fermentation technique before several thousand just be familiar with by people, China is the ancient civilized country of fermentation industry, fermentation technique is widely used in daily life, picture fermentation makes large flat bread, deep-fried twisted dough sticks, steamed bun and steamed stuffed bun, or food becomes sour, article go rotten, but fermentation not only covers fermentation as its implication of specialized vocabulary and makes large flat bread, deep-fried twisted dough sticks, steamed bun and steamed stuffed bun, prior means suitability for industrialized production wine and the alcoholic beverage referring to use fermentation, food and foodstuff additive, feed and fodder additives, medicine and chemical materials etc., therefore the fermentation of our present indication imparts different implications already, refer to the chemical reaction that life entity carries out and physiological change, that diversified biochemical reaction removes continuous local behavior according to the genetic information that life entity itself has, to obtain energy to the process of the activity of sustaining life, refer to people by the vital movement of microorganism under aerobic or oxygen free condition to prepare microbial cells itself, or the process of direct meta-bolites or secondary metabolite, originally the fermentative production of people is only confined to workshop-based fermentative production, through long-term practice, progressively move towards bionic category from workshop-based fermentation production technology, therefore the performance requriements of fermentative production to fermentation equipment is also more and more higher, the fermentation equipment that current production is commonly used is fermentor tank, fermentor tank refers to the industrial device being used for carrying out fermentable, its main body is generally the pillar cylinder made with stainless steel plate, its volume less than one cubic metre to hundreds of cubic meter, be characterized in that design is upper vertebration, rationally, steam sterilizing can be tolerated, there are certain turndown ratio and material and transmission ofenergy performance strong, generally, the generation controlling miscellaneous bacteria is especially needed in fermenting process, if pollute miscellaneous bacteria or phage in fermenting process, the carrying out of fermenting process can be affected, the output of leavened prod is caused to reduce, even can cause the failure of whole fermenting process, leavened prod is required all to outwell, but often there is cleaning dead angle in existing fermentation equipment structure, easily grow other bacteriums, strengthen pollution level, this ferments unsuccessfully to totally unfavorable even the causing of fermenting process, therefore, seek to design a kind of air lift type seeding tank fermentation unit, make it rational in infrastructure, so that overall cleaning comprehensively, improve fermenting process sterility and fermented quality.

Summary of the invention:

Goal of the invention of the present invention is the shortcoming overcoming prior art existence, a kind of air lift type strain fermentation device of design is proposed, to solve the many not easy cleanings in existing fermentation unit dead angle, leavened prod shifts out and thoroughly do not cause residue to pollute the problem of breed bacteria, be convenient to dismounting, and cleaning thoroughly, improves the sterility of yeasting.

In order to realize foregoing invention object, its agent structure of the air lift type strain fermentation device that the present invention relates to comprises inner barrel, flange boss, end flange, depressed part, fast-assembling flange lid, fast-assembling flange lid boss, porthole, the first lamp visor, lamp mirror mouth, discharge port, temperature-measuring port, material-feeding port, inoculation mouth, inlet mouth, venting port, the second lamp visor, discharge nozzle, discharge nozzle bottom, bleeder valve, thermometric lid, material-feeding port plug, inoculation lid, intake valve, vent valve, sealing-ring, clip and inlet pipe, the inner barrel of post core structure is the metallic cylinder of wall thickness 2 ~ 4mm, the top perimeter edge place of inner barrel is provided with flange boss, the upper surface middle position of flange of the metallic end is provided with curve recess portion, be welded and fixed after the bottom coaxialalignment of flange of the metallic end and inner barrel, the border of the fast-assembling flange lid that metallic substance is made is with fast-assembling flange lid boss, fast-assembling flange lid boss is identical with the outer circumference diameter size of the flange boss of inner barrel, the circle centre position that fast-assembling flange covers is provided with tapped porthole, first lamp visor is housed on the upside of porthole, fast-assembling flange covers the place's of keeping to the side periphery and is respectively equipped with lamp mirror mouth, discharge port, temperature-measuring port, material-feeding port, inoculation mouth, inlet mouth and venting port, the second lamp visor lamp mirror mouth is equipped with, discharge nozzle is through discharge port, the recess contact of discharge nozzle bottom and end flange, the upper end of discharge nozzle is provided with bleeder valve, temperature-measuring port is provided with thermometric lid, is with female material-feeding port to be connected with material-feeding port plug screw-type, inoculation mouth is provided with inoculation lid, and inlet pipe stretches out inner barrel through inlet mouth bottom inner barrel, and the top end of inlet pipe is provided with intake valve, exhaust ports be equipped with vent valve and with the intracavity inter-connection of inner barrel, between the flange boss of fast-assembling flange lid boss and inner barrel, sealing-ring is housed and border alignment, then is stuck on the flange boss of fast-assembling flange lid boss and inner barrel with clip, fast-assembling flange lid and inner barrel are fixed and seals, before the present invention uses, in sterilisable chamber, bacterial classification is loaded in bacterial classification triangular flask by processing requirement, cleaning and sterilizing is carried out to tank body, then close intake valve, slowly open vent valve, make tank pressure slowly close to zero, close vent valve, unscrew inoculation lid, put into alcohol ring and light alcohol, open inoculation lid, and slightly drive air valve into, slightly ventilate in tank, make inoculation mouth slightly have gas to discharge, by triangular flask bacterial classification under flame shielding, pour in inoculation mouth and carry out spawn culture, after spawn culture terminates, regulate and enter inlet pipe gaseous tension, make inner barrel internal pressure be greater than solid pressure tank, open bleeder valve, bacterial classification moves on to solid tank from discharge nozzle under pressure, until seed has moved, do further fermentation, realize air lift type strain fermentation.

Compared with prior art, device is convenient to dismounting cleaning in the present invention, and tank body is thorough, noresidue without dead angle design, leavened prod to be shifted out, and reduces bacteria breed, improves the sterility of yeasting; Its one-piece construction is simple, and manufacturing process is ripe, and being dismounted for multiple times is nimble, good airproof performance, and fermented quality is high, and environment for use is friendly.
