Detailed description of the invention
As shown in Figure 1, this utility model comprises material-compound tank 1, filter 2, dehvery pump 3, flow control valve 4, effusion meter 5, preheating cooler 6, heating mixer 9, constant temperature steriliser 7, back pressure compensation device 12, control system 11, first temperature sensor 13, second temperature sensor 10, first pressure transducer 8 and the second pressure transducer 14.
Be contained with material subject to sterilization in material-compound tank 1, the outlet at bottom of material-compound tank 1 is connected with dehvery pump 3 by filter 2.The foreign material such as the bulky grain that first may be existed in filtering material after filter 2 by material-compound tank 1 outlet at bottom material out and the rope made of hemp, the material after filter 2 filtering foreign material is passed through the Output pressure of pump to preheating cooler 6 by dehvery pump 3.Flow control valve 4 and effusion meter 5 are all arranged on the pipeline between dehvery pump 3 and preheating cooler 6, can be regulated the uninterrupted of the material that dehvery pump 3 exports by flow control valve 4, the flow of the material that dehvery pump 3 exports can be detected by effusion meter 5 in real time.Regulated by the uninterrupted of material on flow control valve 4 pairs of pipelines, compare and adopt the rotating speed of Frequency Converter Control dehvery pump 3 to regulate and control the flow of material, actual regulating effect is far better.
Preheating cooler 6 is made up of two spiral channels, and each spiral channel can be a spiral heat exchanger, and each passage all has corresponding import and outlet, and the material through these two passages will carry out exchange heat.These two passages are designated as first passage and second channel respectively; Wherein, the import of first passage is connected with dehvery pump 3 by effusion meter 5 and flow control valve 4, and the outlet of first passage connects with the import of heating mixer 9; The import of second channel is connected by the outlet of constant temperature steriliser with heating mixer 9, and the outlet of second channel connects with back pressure compensation device 12.
First the material exported by dehvery pump 3 flows into the first passage in preheating cooler 6, flows out to heating mixer 9 afterwards by first passage.Heating mixer 9 can be injecting type heating mixer (such as venturi type heating mixer) or normal spiral plate type heat exchanger.External steam flows in heating mixer 9 continuously, and material enters in heating mixer 9 and steam, and temperature rises instantaneously, and material after intensification (herein also can weighing liquid) flows into constant temperature steriliser 7 by the outlet of heating mixer 9.Constant temperature steriliser 7 is Novel double-channel spiral plate type structures, similar with the internal structure of preheating cooler 6, but difference is, interior two passages of preheating cooler 6 are separated from one another, independent of each other, and interior two passages of constant temperature steriliser 7 join end to end thus define a passage.Material maintains original high temperature in constant temperature steriliser 7, thus implements high temperature constant temperature sterilizing.Material after sterilizing is output in the second channel in preheating cooler 6.Because the material after sterilizing belongs to high-temperature material (or claiming heat material), material before sterilizing in first passage is low-temperature material (or claiming cold burden), and heat material is gone against the stream in two passages with cold burden, and realizes exchanging heat, instant heating material carries out preheating to cold burden, and cold burden cools heat material.Export by second channel the material flowed out and export sterilized fermentation tank to after back pressure compensation device 12.
In this utility model, multilamellar preheating cooler can also be set, connect by two or more preheating cooler, thus form multilamellar preheating cooling system, the temperature of material can be made full use of like this, reclaim heat energy more completely, energy-conservation greatly.
The setting of back pressure compensation device 12 is to regulate the pressure of material after the sterilizing exported by second channel outlet.This be due to: the material after sterilizing exports fermentation tank to, along with increasing of material in fermentation tank, in it, feed liquid liquid level rises, and then make pressure increase in it, in fermentation tank, the increase of pressure causes the material exported by second channel to flow into slowing of fermentation tank, the change of material flow can make disinfection system unstable working condition, affects sterilization quality.This utility model is by the pipeline that connects arranging the second pressure transducer 14(and can be arranged on the pipeline that back pressure compensation device 12 front or rear connect exporting with second channel), by the pressure of material after sterilizing on the second pressure transducer 14 in real time signal piping, and testing result is sent to back pressure compensation device 12, back pressure compensation device 12 adjusts the pressure of material after sterilizing in real time according to the data that the second pressure transducer 14 sends, and makes the material after sterilizing can be delivered to fermentation tank evenly.Back pressure compensation device 12 can be realized by corresponding control system and control valve, it should be noted that, carries out adjustment herein and belongs to fine setting, can ignore the change of mass flow in adjustment process to the pressure of material.
This utility model is in order to ensure sterilization effect, and the temperature imported and exported according to heating mixer 9 by control system 11 and import department's Steam pressure control flow control valve 4 regulate mass flow, and then controls sterilization time, to ensure that sterilizing is thorough.Specifically, the inlet ductwork of heating mixer 9 arranges the first temperature sensor 13, detect the temperature in heating mixer 9 inlet ductwork by the first temperature sensor 13; The export pipeline of heating mixer 9 arranges the second temperature sensor 10, the temperature on heating mixer 9 export pipeline is detected by the second temperature sensor 10, the inlet ductwork of heating mixer 9 arranges the first pressure transducer 8, is detected the pressure (i.e. steam pressure) in heating mixer 9 inlet ductwork by the first pressure transducer 8.First temperature sensor 13, second temperature sensor 10 and the first pressure transducer 8 all connect with control system 11, and the data that three detects all are sent to control system 11.
Control system 11 is PLC or DCS control system (dcs, Distributed Control System).Control system 11 is according to the received temperature at heating mixer 9 import and export place and the pressure of import department, and control flow check adjustable valve 4 performs corresponding action, regulates and controls with the mass flow exported dehvery pump 3.Effusion meter 5 can detect the flow of material on dehvery pump 3 output pipe in real time, and testing result is sent to control system 11.
Compared with the outer continuous-flow sterilizing installation of existing tank, adopt this utility model to carry out continuous sterilization, steam saving rate can reach more than 70%, and cooling water saves more than 99%.No significant difference before the color and luster of material and sterilizing after sterilizing, material heated time is short, and nutritional labeling is destroyed few.Extensive to the requirement of material, the materials such as routine Semen Maydis pulp, soybean cake powder, Semen Maydis powder all can carry out sterilizing.
This utility model equipment is few, rational in infrastructure, simple to operate, and in sterilization process, noiselessness is shockproof; Sterilization time is short, and work efficiency is high, and fermentation tank utilization rate is high; Energy resource consumption is few; Required steam pressure is low, uses vapor equalization, can avoid using vapour peak; Can Automated condtrol be adopted, not only can reduce labor intensity, and the microbiological contamination probability that can also reduce manual operation and bring; Can ensure that sterilizing is thorough.
