Abstract
The utility model relates to a fermentation defoaming agent adding device for yeast production, which comprises a defoaming agent supplementing tank and a fermentation tank, wherein the top of the fermentation tank is connected with a quantitative tank, the quantitative tank is connected with the defoaming agent supplementing tank, the fermentation tank is provided with a probe-type liquid level transmitter, and the probe-type liquid level transmitter is connected with an automatic feedback control module. According to the fermentation defoaming agent adding device for yeast production disclosed by the utility model, a fed-batch scheme design is adopted, defoaming agent fed-batch is carried out on the top of the fermentation tank to be directly used for foam by adopting a simple feedback control system according to total defoaming oil consumption in a single-batch fermentation process, and the effect is taken rapidly. In order to solve the problem of excessive add, a small tank is used for quantification, the defoaming agent is added in a mode of flowing by gravity from the top of the fermentation tank, and by being combined with fed-batch process optimization, the device plays a good role of defoaming, simultaneously an irreversible result caused by exces addition is avoided.
Description
Technical field
The utility model relates to primary yeast production fermentation skimmer adding set, relates to yeast fermentation and makes the field.
Background technology
Skimmer be one type widely used in the biological fermentation industry, be used for eliminating the foamy chemical agent of mistake that fermenting process produces.Too much foam is bigger to biological fermentation harm, can influence stocking volume, pollutes easily, influences the mass transfer of oxygen in fermented liquid, and then influences fermented quality and yield etc.Yeast fermentation is raw material with molasses, adopts a large amount of ventilation of Root's blower to carry out aerobic fermentation, because air feed is sufficient, material viscosity is big, is easy to generate a large amount of barms in the fermenting process, and the quick defoaming requirement that yeast fermentation production faces is more outstanding.Fermentor tank bulky because of yeast fermentation uses solves the most economical method of bubble-related issues, generally is that skimmer stream adds.
Skimmer is to biological fermentation, and especially yeast fermentation is a double-edged sword.On the one hand, ensure the carrying out of normal ventilating fermentation process, avoid foam many and overflow jar, must use skimmer; But then, if skimmer adds too much, can influence the mass transfer of oxygen in fermented liquid, cause the fermenting process anoxic, alcohol increases fast, and yeast growth is slow, and yield reduces, downgrade.
Traditional skimmer addition means generally is that skimmer is mixed with emulsion, through the fermentation liquid level feedback control, when liquid level is higher in fermentor tank; On the circulating line of yeast fermentation outer circulation cooling, be with to press to add, play the effect of eliminating barm, this adds mode level of automation height; But need to continue stock, consumes energy, skimmer adds the pressure height simultaneously; Controlled feedback is untimely, and the situation that the ubiquity add-on is too much is in system design; For fear of adding too much, often take extremely accurate expensive liquid level monitoring and anti-crawl agentfoam oil to add system again, but practical effect is not good enough.
Summary of the invention
For solving the problems of the technologies described above; The utility model provides primary yeast production fermentation skimmer adding set, adds conceptual design through adopting stream, with reference to the anti-crawl agentfoam oil total flow of single batch fermentation process; Adopt simple feedback control system; Add at fermentor tank jacking row skimmer stream, directly act on foam, onset is rapid.For solving the problem of excessive interpolation, use canister quantitative, the mode of fermentation tank deck flow by gravity is added skimmer, combines stream to add program optimization simultaneously, when playing good defoaming effect, guarantees that excessive flow does not add, and produces irreversible consequence.，
The above-mentioned purpose of the utility model is to realize through such technical scheme: yeast production fermentation skimmer adding set; Comprise skimmer fluid infusion jar; Fermentor tank, the fermentor tank top connects quantitative pot, and quantitative pot connects skimmer fluid infusion jar; Fermentor tank is equipped with the probe-type fluid level transmitter, and the probe-type fluid level transmitter connects the automatic feedback control module.
Said fermentor tank top connects quantitative pot through SV, and SV connects the automatic feedback control module.
Said automatic feedback control module is provided with alarm module.
Said quantitative pot is provided with the liquid level sign.
The utility model yeast production fermentation skimmer adding set, the automatic feedback control module is provided with alarm module, can remind operator to strengthen paying close attention to, and can carry out manual intervention in case of necessity.Probe-type fluid level transmitter cost cost is significantly less than ultrasonic type and the induction type liquid level device that fluffs, and practices thrift equipment cost greatly.Quantitative pot is provided with the liquid level sign; Be convenient to check the consumption situation; Before the fermentation beginning, according to the unit consumption consumption, manually in the high position gravity flow skimmer fluid infusion jar in the quantitative pot of fermentation tank deck the skimmer of adding suitable amounts; Break down even if guarantee feedback control, skimmer total amount stream adds also can not be excessive.The control of the utility model device is effective, and the construction use cost is low, because of skimmer can directly measure, also is convenient to the statistic of attribute in the fermenting process.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the utility model apparatus structure synoptic diagram.
Embodiment
As shown in Figure 1; Yeast production fermentation skimmer adding set comprises skimmer fluid infusion jar 1, fermentor tank 2; Fermentor tank 2 tops connect quantitative pot 3; Quantitative pot 3 connects skimmer fluid infusion jar 1, and fermentor tank 2 is equipped with probe-type fluid level transmitter 4, and probe-type fluid level transmitter 4 connects automatic feedback control module 5.Said fermentor tank 2 tops connect quantitative pot 3 through SV 6, and SV 6 connects automatic feedback control module 5.Said automatic feedback control module 5 is provided with alarm module 7.Said quantitative pot 3 is provided with the liquid level sign.
Embodiment:
High and low position two cover probe-type fluid level transmitters 4 are set on fermentor tank 2 tops; Through automatic feedback control module 5, the foam layer 8 of fermentor tank 2 is highly carried out upper limit fuzzy control, reach probe height and promptly feed back automatic interpolation skimmer; Directly add skimmer from tank deck; Directly act on foam layer 8, effect is effective rapidly, and addition is few.
Automatic feedback control module 5 employing double loop controllers, during the program setting low alarm, anti-crawl agentfoam oil adds 2 seconds and stopped 5 seconds, during full level alarm; The anti-crawl agentfoam oil even flow adds, and adds 5 seconds, stops 2 seconds; This fed-batch mode can fine control overflows a jar risk, avoids adding excessive skimmer simultaneously.
