Embodiment 1

[0034] like Figure 2-Figure 3 As shown, the present invention is used for the heat exchange system of the ultra-high pressure refrigerating equipment, including the outer heat exchange assembly 3 arranged outside the high pressure refrigerating chamber 9 of the ultra-high pressure refrigerating equipment and the inner heat exchange assembly 2 arranged in the high pressure refrigerating chamber 9, The inner heat exchange assembly 2 is spirally arranged on the inner wall of the high-pressure freezing chamber 9, and the refrigerant inlet and the refrigerant outlet of the inner heat exchange assembly 2 are both arranged on the bottom plug 4 at the bottom of the high-pressure freezing chamber 9, and the built-in The refrigerant inlet and refrigerant outlet of the heat exchange assembly 2 are connected to the external water pump through the bottom block 4 for forced circulation, which can directly cool the medium in the high-pressure freezing chamber 9, and establish a medium in the...

Embodiment 2

[0040] like Figure 4 As shown, the ultra-high pressure refrigeration equipment of the present invention comprises the heat exchange system described in Example 1, the ultra-high pressure reactor 6 and the supercharger 5 for pressurizing the ultra-high pressure reactor 6;

[0041] The ultra-high pressure reactor 6 is provided with an ultra-high pressure vessel 1, and a high-pressure freezing chamber 9 is formed in the ultra-high pressure vessel 1 for holding materials, and the outer heat exchange component 3 is sleeved in the ultra-high pressure vessel 1. Outside, the internal heat exchange assembly 2 is arranged in the high-pressure freezing chamber 9 of the ultra-high pressure vessel 1, and the bottom of the ultra-high pressure vessel 1 is provided with a mounting frame 7 for fixing in the ultra-high pressure reactor 6.

[0042] Further, the bottom of the ultra-high pressure reactor 6 is provided with a support plate 8 for fixing.

Embodiment 3

[0044] On the basis of Example 2, as Figure 5 As shown, a detachable barrel-shaped material basket 10 is installed in the high-pressure freezing chamber 9 of the ultra-high pressure refrigeration equipment, and a guide tube 11 is arranged in the middle of the material basket 10 to make the upper part of the material basket 10 temperature. The lower medium flows down along the basket wall of the material basket 10, and the higher temperature medium at the lower part of the material basket 10 can flow upward from the guide pipe 11 in the middle of the material basket 10 to form a circulating flow, which effectively improves the high-pressure freezing chamber 9. heat conduction effect.

[0045]Further, hooks extending outward are formed on the top of the basket 10, so that the basket 10 is clamped with the high-pressure freezing chamber 9, and it is convenient to remove the frozen products from the material after the ultra-high-pressure freezing process is completed. out of the...

Abstract

The invention discloses a heat exchange system for ultrahigh-pressure refrigeration equipment. The heat exchange system includes an external heat exchange assembly which is arranged outside a high-pressure freezing cavity of the ultrahigh-pressure freezing equipment, and an internal heat exchange assembly which is arranged in the high-pressure freezing cavity. The built-in heat exchange assembly is spirally arranged on the inner wall of the high-pressure freezing cavity; a refrigerant inlet and a refrigerant outlet of the built-in heat exchange assembly are both formed in a bottom plug at thebottom of the high-pressure freezing cavity and connected with an external water pump; and thermal power for promoting a medium to flow is established in the high-pressure freezing cavity. By arranging the built-in heat exchange assembly in a high-pressure freezing cavity of the ultrahigh-pressure freezing equipment., the heat exchange pipe of the built-in heat exchange assembly is spirally arranged along the axis of the inner wall of the high-pressure freezing cavity and a medium placed in the high-pressure freezing cavity can be directly cooled, wherein the medium on the upper portion in thehigh-pressure freezing cavity and the medium on the lower portion in the high-pressure freezing cavity form a circularly-flowing thermal power field, so that on one hand, heat exchange is enhanced through convection, on the other hand, the temperature of the thermal power field is uniform, and heat balance is achieved.

Description

technical field [0001] The invention belongs to the technical field of ultra-high pressure equipment, and in particular relates to a heat exchange system for ultra-high pressure refrigeration equipment and ultra-high pressure refrigeration equipment. Background technique [0002] Ultra-high pressure freezing technology is a new freezing technology. The material is put into an ultra-high pressure container filled with liquid medium, sealed and then pressurized to about 200MPa, and the container is cooled down to the set temperature (-20°C) by refrigeration. After the material is fully cooled to the set temperature (-20°C), the pressure is suddenly released to one atmospheric pressure, and the material is instantly frozen and frozen. During the freezing process of the material, the faster the freezing speed, the smaller and more uniform the ice crystals formed inside the material, and the smaller the impact on the quality of the material. [0003] In order to achieve ultra-hi...
