Detailed Description
Example 1
As shown in fig. 1, an aseptic quick raw material cooling device comprises a main pipeline 13 communicated with the lower part of the left side of a raw material sterilization tank 12 and an air extraction pipe 18 communicated with the upper part of the right side of the raw material sterilization tank 12, wherein the main pipeline 13 is sequentially provided with a first electric valve 1, an air filter 2 and an air pre-cooling unit 6 from left to right, the air extraction pipe 18 is provided with a seventh electric valve 11, one end of the air extraction pipe 18, which is far away from the raw material sterilization tank 12, is provided with a vacuum pump, and the vacuum pump is a water ring vacuum pump 10. The main conduit 13 on the left side of the first electrically operated valve 1 communicates with a compressed air conduit.
The air flow output by the air pre-cooling unit 6 is larger than that of the vacuum pump, the gas pressure in the raw material cooling tank is larger than the external atmospheric pressure, and the filtering precision of the air filter 2 is 0.01 micrometer.
The air pre-cooling unit 6 is used for compressing and cooling air and providing cold air into the raw material sterilization tank 12. The temperature of compressed air at the inlet of the air precooling unit is less than or equal to 30 ℃, the pressure is 0.2 to 0.25MPa, the outlet temperature is less than or equal to 7 ℃, the pressure is 0.15 to 0.2MPa, and the output quantity of cold air is 12m 3 And/min. Therefore, the raw material sterilization tank 12 can be quickly filled with the pressurized low-temperature cold air in a short time, and the low-temperature cold air is fully mixed with the raw materials in the raw material sterilization tank 12, so that the aim of cooling the raw materials is fulfilled.
The working process of the invention is as follows:
the first electric valve 1 and the seventh electric valve 11 are opened, under the action of the air pre-cooling unit 6, the outside air is filtered by the air filter 2, then flows through the air pre-cooling unit 6 through the main pipeline 13 to be cooled, then flows into the raw material sterilization tank 12 to cool the raw materials inside the raw materials, and is pumped out by the water ring vacuum pump 10 through the air pumping pipe 18.
The pressure and the output quantity of the cold air of the air precooling unit are larger than the negative pressure value and the discharge quantity of the water ring type negative pressure pump, so that the raw material cooling tank can be effectively ensured to be always kept at the positive pressure under the action of the cold air, and the aseptic state in the raw material cooling process can be ensured.
Since the diameter of the cell of a general bacterium is 0.2. mu.m, the diameter of the smallest bacterial spore is not larger than 0.02. mu.m. The filter element of the air filter 2 can filter substances with a diameter of 0.01 μm, thus reliably ensuring that the air entering the raw material sterilizing tank 12 is completely sterile.
Because the raw material sterilization tank 12 is filled with a large amount of raw materials, the filling coefficient is 0.75, and the raw materials are in a dynamic state under the action of the stirring shaft in the raw material sterilization tank 12, the pressure of the pressurized cold air is attenuated instantly after entering the raw material sterilization tank 12, and the heat exchange with the raw materials in the raw material sterilization tank 12 cannot be fully carried out. After the water-ring vacuum pump 10 is arranged, cold air in the raw material sterilization tank 12 can flow orderly, the heat exchange is carried out after the heat exchange is carried out by combining the raw material and the raw material fully in a short time, and then the gas with the temperature basically equal to that of the raw material in the raw material sterilization tank 12 is pumped away by the water-ring vacuum pump 10, so that new cold air enters from the left end of the raw material sterilization tank 12. This rapidly reduces the temperature of the feedstock to the desired temperature. Thereby improving the production efficiency.
The right end of the main pipeline 13 is connected with the lower part of the left side of the raw material sterilizing tank 12, the exhaust pipe 18 is connected with the upper part of the right side of the raw material sterilizing tank 12, and the main pipeline 13 cannot be blocked by the raw materials in the raw material sterilizing tank 12 because the cold air flowing into the raw material sterilizing tank 12 from the main pipeline 13 has the positive pressure of more than 0.15 Mpa. An air exhaust pipe 18 is connected to an upper portion of the raw material sterilizing tank 12 so that the cool air can be more sufficiently heat-exchanged with the cooled raw material in the raw material sterilizing tank 12.
Example 2
As shown in fig. 2, the present embodiment is different from embodiment 1 in that:
be equipped with third motorised valve 5 on the trunk line 13 between air cleaner 2 and the raw materials sterilization jar 12, be connected with first bypass pipe 14 on the trunk line 13 between raw materials sterilization jar 12 and the third motorised valve 5, be connected with second bypass pipe 15 on the trunk line 13 between third motorised valve 5 and the raw materials sterilization jar 12, the air inlet of air precooling unit 6 links to each other with the lower extreme of first bypass pipe 14, the gas outlet of air precooling unit 6 links to each other with the lower extreme of second bypass pipe 15, be equipped with second motorised valve 4 on the first bypass pipe 14, be equipped with fourth motorised valve 8 on the second bypass pipe 15.
After the first electric valve 1, the second electric valve 4, the fourth electric valve 8 and the seventh electric valve 11 are opened and the third electric valve 5 is closed, compressed air enters the main pipeline 13 and then sequentially flows through the first electric valve 1, the air filter 2, the second electric valve 4, the air pre-cooler unit 6 and the fourth electric valve 8 and then enters the raw material sterilization tank 12 to cool raw materials.
When the main pipe 13 and the air filter 2 need to be sterilized, the first electric valve 1, the second electric valve 4, the fourth electric valve 8 and the seventh electric valve 11 are closed, and the third electric valve 5 is opened. Then, high-temperature steam (over 121 ℃) is filled into the raw material sterilization tank 12, and after the high-temperature steam enters the main pipeline 13 according to the arrow direction shown in fig. 3, the main pipeline 13 and the air filter 2 are sterilized at high temperature, so that bacteria in the air filter 2 are killed. In the sterilization process, high-temperature steam cannot enter the air pre-cooling unit 6, so that the air pre-cooling unit 6 is protected.
Example 3
As shown in fig. 4, the present embodiment is different from embodiment 2 in that:
a hydrogen peroxide outlet pipe 16 is connected to a first bypass pipe 14 between the second electric valve 4 and the air pre-cooling unit 6, a return pipe 17 is connected to a second bypass pipe 15 between the fourth electric valve 8 and the air pre-cooling unit 6, a fifth electric valve 3 is arranged on the hydrogen peroxide outlet pipe 16, and a sixth electric valve 9 is arranged on the return pipe 17. A hydrogen peroxide sterilizing unit 7 is connected between the lower end of the hydrogen peroxide outlet pipe 16 and the left end of the return pipe 17.
Since the air introduced into the material sterilizing tank 12 must be kept completely sterile, the material sterilizing tank 12 and all the piping and valves introduced therein must be sterilized before the material is introduced into the material sterilizing tank 12. The most economical and common sterilization method is sterilization using high temperature steam above 121 ℃. Although the method of sterilizing the air filter 2 and the main duct 13 has been described in example 2, many components of the air pre-cooler 6, various electrical components and control components cannot withstand such high temperature and humidity, and even all of them cannot meet the requirements of the high-end components of the inlet. Therefore, the hydrogen peroxide sterilization method is adopted for sterilizing the air pre-cooler unit 6, so that the air pre-cooler unit 6 which cannot be sterilized at high temperature can also meet the requirement of complete sterility.
The method for sterilizing the air precooler unit 6 comprises the following steps:
the second electric valve 4 and the fourth electric valve 8 are closed, the fifth electric valve 3 and the sixth electric valve 9 are opened, and the hydrogen peroxide-containing air generated by the hydrogen peroxide sterilization unit 7 flows in the direction indicated by the arrow in fig. 5, thereby sterilizing the air pre-cooling unit 6.
The above-mentioned embodiments are described in detail and specifically for the purpose of illustrating the technical ideas and features of the present invention, and it is an object of the present invention to enable those skilled in the art to understand the contents of the present invention and to implement the same, but not to limit the present invention only by the embodiments, and it is not limited to the scope of the present invention, i.e. equivalent changes or modifications made within the spirit of the present invention, and it is within the scope of the present invention for those skilled in the art to make local modifications within the system and changes or modifications between subsystems without departing from the structure of the present invention. At present, the technical scheme of the application has been subjected to pilot plant test, namely small-scale experiment before large-scale mass production of products; after the pilot test is finished, the investigation for the use of the user is carried out in a small range, and the investigation result shows that the satisfaction degree of the user is higher; now, the preparation of products for official production and industrialization have been started.
