It should be noted that, the indirect sterilization module 170 is a tubular heating module, and the tubular heating module is connected to the tubular cooling module 180 through the second bridging main board 150, and the tubular heating module is used for heating the material in a tubular manner, so that the material is heated to a second preset sterilization temperature, where the second preset sterilization temperature is lower than the first preset sterilization temperature. Specifically, the sterilization principle of the tubular heating module is that materials are introduced into an inner tube bundle, hot water is introduced between the inner tube bundle and an outer tube sleeve, and the hot water and the materials exchange heat under the heat conduction action of the tube bundle (metal heat exchange tubes) so as to heat the materials to a second preset sterilization temperature; the cooling principle of the tubular cooling module 180 is that materials are introduced into an inner tube bundle, cooling water is introduced between the inner tube bundle and an outer tube sleeve, and the cooling water and the materials exchange heat under the heat conduction action of the tube bundle (metal heat exchange tubes) so as to cool the materials.

In this embodiment, the tubular heating module and the tubular cooling module 180 are combined to form a tubular heat exchanger, wherein the tubular heating module is a hot end of the tubular heat exchanger, and the tubular cooling module 180 is a cold end of the tubular heat exchanger, i.e. water between the inner tube bundle and the outer tube sleeve can flow between the tubular heating module and the tubular cooling module 180. Specifically, in the process of cooling the material by the tube cooling module 180, the cooling water between the inner tube bundle and the outer tube sleeve absorbs the heat of the material to raise the temperature so as to realize the heat recovery function, and thereafter the cooling water with the raised temperature is heated to become hot water under the action of the tube heat exchanger and flows to the tube heating module so as to sterilize the material at high temperature. Likewise, in the process of high-temperature sterilization of the material by the tubular heating module, the temperature of the hot water between the inner tube bundle and the outer tube sleeve is reduced after heat release of the material, so as to realize the heat release function, and the hot water with reduced temperature is reduced to be cooling water under the action of the tubular heat exchanger and flows to the tubular cooling module 180 so as to cool the material.

The indirect sterilization module 170 includes a heating unit 171 and a sterilization unit 172. The heating unit 171 is disposed in front of the sterilizing unit 172, that is, the material passes through the heating unit 171 and then the sterilizing unit 172 in the indirect sterilization process. Specifically, the heating temperature of the heating unit 171 is lower than that of the sterilizing unit 172, the heating unit 171 is used for primarily heating the material to improve the activity of the material, and the sterilizing unit 172 is used for heating the material to a second preset sterilizing temperature to realize the high-temperature sterilizing function.

The heating unit 171 includes a first tube changing element 1711, a second tube changing element 1712, a first expansion tank 1713, and a second circulating water pump 1714. The first tube change element 1711, the second tube change element 1712, and the first expansion tank 1713 are connected end to end and form a second circulation flow path, and the tube cooling module 180 and the preheating module 240 are connected to the second circulation flow path. The first expansion tank 1713 is used for storing hot water, the first pipe exchanging element 1711 is used for transferring heat of steam to hot water so that the hot water is quickly heated to a primary heating temperature under the heat exchange effect of the steam, and the second pipe exchanging element 1712 is used for transferring heat of the hot water to materials so that the materials are quickly heated to the primary heating temperature under the heat exchange effect of the hot water. Therefore, the heat of the steam can be quickly transferred to the material in a twice heat exchange mode, so that the material is heated to the initial heating temperature, and the effect of improving the activity of the material is achieved.

In this embodiment, the number of the second tube-changing elements 1712 is two, the two second tube-changing elements 1712 are sequentially connected, and the two second tube-changing elements 1712 act together to exchange heat to the material sequentially, so as to ensure that the material is heated to the initial heating temperature quickly, and improve the stability of material temperature rise. However, the number of the second tube changing elements 1712 may be one or three in other embodiments, and the number of the second tube changing elements 1712 is not particularly limited.

The sterilization unit 172 includes a third tube changing element 1721, a fourth tube changing element 1722, a second expansion tank 1723, and a third circulating water pump 1724.

The second expansion tank 1723 is used for storing hot water, the third pipe exchanging element 1721 is used for transferring heat of steam to hot water so that the hot water is quickly heated to a second preset sterilization temperature under the heat exchange effect of the steam, and the fourth pipe exchanging element 1722 is used for transferring heat of the hot water to materials so that the materials are quickly heated to the second preset sterilization temperature under the heat exchange effect of the hot water. Therefore, the heat of the steam can be quickly transferred to the material in a twice heat exchange mode, so that the material is heated to a second preset sterilization temperature, and a high-temperature sterilization effect is achieved.

In this embodiment, the indirect sterilization module 170 heats the material in two stages by adopting a two-stage hot water loop (a second circulation flow path and a third circulation flow path) to ensure the stability of the material rising to the second preset sterilization temperature. Specifically, under the control action of the second bridging motherboard 150 (the control action of the second bridging motherboard 150 refers to bridging through the second bridging motherboard 150, so as to realize mode conversion of one of the heating unit 171, the tubular cooling module 180 and the preheating module 240 used alone or a plurality of them together), the second circulation flow path can selectively supply water to the heating unit 171, the tubular cooling module 180 and the preheating module 240 according to different modes, so as to respectively realize the primary heating, cooling down and preheating functions of the materials, which is convenient and fast, and is beneficial to improving the stability of the system, but in this way, the second circulation flow path in the heating unit 171 simultaneously involves switching of a plurality of pipeline paths, the temperature control is not stable enough, therefore, the indirect sterilization module 170 is divided into the heating unit 171 and the sterilization unit 172, and the independent third circulation flow path is utilized to supply water to the sterilization unit 172 (the second circulation flow path and the third circulation flow path are mutually independent), so as to realize the high-temperature sterilization function of the materials, which is beneficial to improving the accuracy of the sterilization temperature control.

It should be noted that the operation principle of the homogenizing module 160 is to compress the material to a higher pressure by compressing the plunger, so that the material is forced to pass through a small gap between the homogenizing valve and the valve seat, and a high turbulence is formed, and the effects of smaller material particle size, free fat globule emulsification and the like are achieved by virtue of collision among the molecules of the material, so that the stability of the material is better. Specifically, the homogenizing module 160 may be selectively activated or deactivated according to the actual situation to meet the production requirements of different kinds of materials. The homogenization module 160 may be used either before or after autoclaving; for the high-temperature sterilization mode of direct heating sterilization, homogenization is generally carried out after high-temperature sterilization; in the high-temperature sterilization method of indirect heat sterilization, homogenization is generally performed before high-temperature sterilization.

In this embodiment, the cooling principle of the plate cooling module 190 is to introduce cooling water into one side of the metal heat exchange plate and introduce materials into the other side of the metal heat exchange plate, and the cooling water and the materials exchange heat under the heat conduction of the metal heat exchange plate so as to cool the materials to the preset feeding temperature. In particular, the plate cooling module 190 has a smaller volume and smaller product pressure drop at the same heat exchange area as compared to the tube cooling module 180 to achieve a higher cooling rate, enabling rapid cooling of the material.
