The multifunctional integrated sterilizer 100 includes a feeding module 110, a first cross-over main board 120, a direct sterilization module 130, a degassing module 140, a second cross-over main board 150, a homogenizing module 160, an indirect sterilization module 170, a tube cooling module 180, a plate cooling module 190, a filling and discharging module 200, a tower water cooling module 210, a first ice water cooling module 220, a second ice water cooling module 230, and a preheating module 240.

The first bridging main board 120 is connected with the direct sterilization module 130 and the degassing module 140 at the same time, the first bridging main board 120 is used for selectively sending materials to the direct sterilization module 130 or the degassing module 140, the direct sterilization module 130 and the degassing module 140 are connected with the second bridging main board 150, the direct sterilization module 130 is used for directly heating and sterilizing the materials and sending the materials to the second bridging main board 150, and the degassing module 140 is used for eliminating bubbles in the materials and sending the materials to the second bridging main board 150. Specifically, if the first bridging main board 120 sends the material to the direct sterilization module 130, it is indicated that the multifunctional comprehensive sterilizer 100 performs high-temperature sterilization on the material by adopting a direct heating sterilization mode; if the first bridging main board 120 sends the material to the degassing module 140, it indicates that the multifunctional comprehensive sterilizer 100 will perform high-temperature sterilization on the material by indirect heating sterilization; the first bridging main board 120 is used for realizing switching between a direct heating sterilization mode and an indirect heating sterilization mode.

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.

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.

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 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.
