the culture medium batch temperature is about 25 ℃ of left and right, when needs carry out high temperature sterilize to it, first directly first 25 ℃ of raw material are transported to jet heater 6 places heating by dnockout pump 4 through heat-exchange device, enter insulation and keep the interior stop of tank 7 about 85 seconds after being heated to 130 ℃, 130 ℃ of high temperature sterilize material keeping output tank 7 from insulation enter in the first spiral-plate heat exchanger 8 from grog feeding mouth 9-2, after 25 ℃ of raw material in 130 ℃ of high temperature sterilize material and the first spiral-plate heat exchanger 8 carry out heat exchange, the temperature reduction of high temperature sterilize material converts the once cooling grog of 80 ℃ to, once cooling grog enters in secondary spiral lamina heat exchanger 11 and with the raw material of 25 ℃, again carries out heat exchange by grog feeding mouth 9-3 again, once the temperature of cooling grog reduced the cooling grog of secondary that converts 40 ℃ to and by finished product pipeline 15, inputted in fermentation tanks this moment, when after this native system remains in operation, the raw material of 25 ℃ enter in secondary spiral lamina heat exchanger 11 and carry out heat exchange preheating for the first time through raw material feeding mouth 9-1 by dnockout pump 4, raw material with 80 ℃ after once cooling grog carries out heat exchange, the raw material temperature rises to 65 ℃ by 25 ℃ and converts a preheated raw meal to and from raw material discharging opening 10-4, by pipeline, enter in the first spiral-plate heat exchanger 8 and carry out heat exchange preheating for the second time, a preheated raw meal and 130 ℃ of high temperature sterilize material carry out after heat exchange converting to the secondary preheating raw material of 115 ℃ and export from raw material discharging opening 10-1, the secondary preheating raw material heat after jet heater 6 by Pipeline transport, deliver into insulation and keep the interior stop of tank 7 about 85 seconds after being heated to 130 ℃, keep tank 7 from insulation again and export the processing of lowering the temperature of the first spiral-plate heat exchanger 8 and secondary spiral lamina heat exchanger 11 to, completing the high-temp. continuous sterilization of whole circulation processes.
Whole system can be by intelligence control system 5 by sterilizing observed temperature feedback signal, regulate the rotating speed of dnockout pump 4 and regulate electromagnetic flowmeter 12, rotating speed by dnockout pump 4 just improves or reduces flow, changes flow and the flow velocity of feed liquid, thereby guarantees the sterilising temp of setting.Technique is as follows to sterilising temp and the time of staying General Requirements of feed liquid in tank 7 is kept in insulation: 130.0～136 ℃ of sterilising temps, and the time of staying is 85～65 seconds; 137.5～138 ℃ of sterilising temps, the time of staying is 47～42 seconds; 139.5～140 ℃ of sterilising temps, the time of staying is 31～28 seconds.
Changing its mixed proportion when jet heater 6 heats with steam is 40 ﹕ 1, original mixed proportion is about 5:1, because system is except the frequent variation of steam pressure is wayward, other all can immobilize, the unique variable that affects system is steam pressure, if steam pressure is on the low side, under certain design temperature, control system can reduce pump speed automatically.Due in the situation that cross section of fluid channel is long-pending equates, feed velocity (m/s) is directly proportional to volume flow, is inversely proportional to flow time, so reduces flow velocity and can extend the time of staying of sterilizing feed liquid in tank 7 is kept in insulation, correspondingly can reduce sterilising temp.More than steam pressure should be 0.3MPa at least, otherwise be difficult to reach sterilising temp; And when steam pressure is higher, the sterilising temp set of adjustable height, or manually lower steam flow.
If the native system project begun newly needs two open type rustless steel spiral-plate heat exchangers of "one off" production, a jet heater, a cover intelligence control system can be configured by following equipment list:
Approximately 500,000 yuan of above apparatus processing expenses, approximately 100,000 yuan of corollary equipment expenses, approximately 100,000 yuan of mounting costs, add up to 700,000 yuan, and the installation period of complete equipment is about 7 days.
With every crowd of culture medium 100m
3For example, approximately 20 tons of needs consumption steam, also need to consume recirculated water in addition and chilled water is lowered the temperature.After using energy-saving continuous sterilization system instead, can steam saving more than 15 tons,, by 200 yuan/tons of steam costs, economize on the use of funds 3000 yuan for every batch,, if, by 3 batch of materials, annually by 330 days, calculate every day, can save nearly 3,000,000 yuan every year.
Use this utility model approximately need invest 700,000 yuan, move rear 3 months and can recoup capital outlay.Rebuilding construction is easy, and after conditions being possessed, construction period only needs about 7 days.Not only energy-saving effect is remarkable, and easy to operate, has the tremendous economic practical value.
