[0022] like Figure 1 As shown, the freezing and blanching device is suitable for preparing pre-prepared dishes, comprising: a combined cooling and heating module 100, a vegetable washing machine 1, a vegetable cutting machine 2, a blanching machine 3, a cooling pool 4, a quick freezer 5 and an air dryer 6; the vegetable washing machine 1, the vegetable cutting machine 2, the blanching machine 3, the cooling pool 4, the quick freezer 5 and the air dryer 6 are connected in sequence; a loop connection is formed between the combined cooling and heating module 100 and the blanching machine 3 to form a heating cycle, and a loop connection is formed between the combined cooling and heating module 100 and the cooling pool 4 to form a cooling cycle.
[0023] The freezing and blanching device proposed in this embodiment has a simple connection method. It replaces the problem that the traditional system requires multiple energy supply devices, improves the energy utilization efficiency in the process of preparing pre-prepared dishes, and reduces the initial investment. The process of blanching vegetables and freezing vegetables can be solved by using one device. By setting the cold and hot combined supply module 100, the same electricity can be used to provide cold and heat in the preparation process of pre-packed dishes, reducing the energy consumption required for blanching vegetables and freezing vegetables, thereby reducing the production cost of pre-prepared dishes. Specifically, the vegetables to be prepared are first washed by a vegetable washing machine 1 to remove mud and dirt, and then enter the automatic vegetable cutting machine 2 to cut the vegetables to a suitable size, and then enter the blanching machine 3. The cold and hot combined supply device 100 containing carbon dioxide medium provides hot water for the blanching machine 3. The blanched vegetables immediately enter the cooling pool 4 for cooling. At this time, the cold and hot combined supply device 100 containing carbon dioxide medium provides cold water for cooling. The next step is to enter the liquid nitrogen freezer 5 for quick freezing, and then air-dry through the air dryer 6, and then packaged to complete the production of pre-prepared dishes. During the preparation of pre-prepared dishes, a frozen blanching device of the present application can improve energy utilization by adding a cold and hot supply module to simultaneously provide heat for the blanching machine during the preparation of pre-packaged dishes and for the cooling pool during the preparation of pre-packaged dishes.
[0024] In one specific embodiment, the blanching machine 3, the cooling pool 4 and the combined heat and cold supply module 100; the blanching machine 3 is connected to the cooling pool 4, the combined heat and cold supply module 100 is connected to the blanching machine 3, and the combined heat and cold supply module 100 is connected to the cooling pool 4; the combined heat and cold supply module 100 includes: a compressor 101, a cooler 102, a heat regenerator 103, a throttle valve 104, an evaporator 105 and a liquid storage tank 106; the compressor 101, the cooler 102, the heat regenerator 103, the throttle valve 104, the evaporator 105 and the liquid storage tank 106 are connected in sequence to form a circulation loop; the cooler 102 is connected to the blanching machine 3, and the evaporator 105 is connected to the cooling pool 4.
[0025] In this embodiment, it should be noted that by adding a combined cold and hot supply module 100, the energy cost consumed in the entire pre-prepared dish preparation process is reduced, and one unit of electricity can provide both cold and heat. Specifically, the combined cold and hot supply system consists of a compressor 101, a gas cooler 102, a regenerator 103, a throttle valve 104, an evaporator 105, and a liquid storage tank 106 to form a closed loop. The low-temperature and low-pressure gas is compressed into high-temperature and high-pressure steam in the compressor 101, raising the temperature of the water to 90°C, and is transferred to the blanching machine 3 through the cooler 102 to blanch the vegetables. At this time, the gas after heat exchange in the cooler 102 is cooled, and after leaving the gas cooler 102, the high-pressure gas is further cooled in the regenerator 103. Then the gas enters the throttle valve 104 to reduce the pressure and temperature, and is partially liquefied. The wet steam enters the evaporator 105 to vaporize and absorb heat. At this time, the medium-temperature water entering the evaporator 105 is cooled to 7°C cooling water and re-enters the cooling pool 4 to cool the blanched vegetables; the low-pressure saturated steam coming out of the liquid storage tank 106 enters the regenerator 103, and the low-pressure side channel absorbs the supercritical fluid on the high-pressure side, and after absorbing heat, it becomes superheated steam and enters the compressor 101 to increase the pressure and temperature, repeating the cycle.
[0026] In one specific embodiment, the outlet end of the compressor 101 is connected to the inlet end of the cooler 102, a loop is provided between the cooler 102 and the blanching machine 3, the outlet end of the cooler 102 is connected to the inlet end of the regenerator 103, the outlet end of the regenerator 103 is connected to the inlet end of the throttle valve 104, the outlet end of the throttle valve 104 is connected to the inlet end of the evaporator 105, the outlet end of the evaporator 105 is connected to the inlet end of the liquid storage tank 106, and the outlet end of the liquid storage tank 106 is connected to the inlet end of the regenerator 103.
[0027] In one specific embodiment, the outlet end of the vegetable washing machine 1 is connected to the inlet end of the vegetable cutting machine 2 by a pipeline, the outlet end of the vegetable cutting machine 2 is connected to the inlet end of the blanching machine 3 by a pipeline, the outlet end of the blanching machine 3 is connected to the inlet end of the cooling pool 4 by a pipeline, the outlet end of the cooling pool 4 is connected to the inlet end of the quick freezer 5 by a pipeline, and the outlet end of the quick freezer 5 is connected to the inlet end of the air dryer 6 by a pipeline.
[0028] In summary, it should be noted that it is advisable to select vegetable varieties suitable for freezing and vegetable varieties with strong resistance to freezing. The vegetable varieties are washed with a vegetable washing machine 1 to remove soil, impurities and pollutants, and then the vegetable varieties are peeled and cut, and the vegetables are peeled or shredded or sliced according to the different product types. At the same time, some vegetables that may be oxidized and browned after peeling are soaked in a solution to protect the color and inhibit oxidation. After that, the vegetables are placed in boiling water in a blanching machine 3 for treatment to reduce the activity of the enzyme so that the taste and color of the frozen vegetables will not deteriorate significantly in a short time. After blanching, immediately enter the cooling pool 4 for cooling, otherwise the product is easy to change color, and the vegetables are placed in cold water for soaking. The water temperature is generally about 5 degrees to 10 degrees, or a cold water spray device or cold air is used for cooling. After that, the freezing temperature is set so that the vegetables are quickly cooled to -15°C within 1 hour, and then frozen and stored for a long time at a temperature of about -18°C. It should also be noted that there are many methods and equipment for quick freezing, such as tunnel-type blast freezer (with a blast cold air temperature of -18–34°C and a wind speed of 30-100 meters per minute), single-type screw quick freezer 5, fluidized bed refrigeration equipment, intermittent contact freezer, and fully automatic flat plate freezer. Finally, an air dryer 6 is used to air dry the quick-frozen vegetables, and then package them after air drying to complete all processes.
[0029] In one specific embodiment, the cooler 102 is a gas cooler.
[0030] In one of the specific embodiments, the carbon dioxide medium is introduced into the interior of the combined cold and hot supply module 100. Simply put, the vegetables to be prepared are first washed in a vegetable washing machine 1 to remove mud and dirt, and then enter the automatic vegetable cutter 2 to cut the vegetables into a suitable size, and then enter the blanching machine 3. The carbon dioxide combined cold and hot supply device provides hot water for the blanching machine 3. The blanched vegetables immediately enter the cooling pool 4 for cooling. At this time, the carbon dioxide combined cold and hot supply device provides cold water for cooling. The next step is to enter the liquid nitrogen freezer for quick freezing, and then air-dry and package to complete the production of pre-prepared dishes. It should be further explained that carbon dioxide is a natural working fluid that does not damage the ozone layer, has no greenhouse effect, and does not pollute the environment.
[0031] It should be noted that, although the freezing and blanching device is introduced as an example in this application, those skilled in the art will understand that this application should not be limited thereto.
