Description

Technical Field

[0001] The utility model relates to the technical field of food production, in particular to a device for rapid freezing of fresh corn puree. Background Art

[0002] The production of corn juice includes multiple steps: material selection → husk and beard removal → cleaning → enzyme inactivation → cooling → scraping and grain collection → pulping → filtration → corn juice → mixing and blending → homogenization → filtration → filling → canning → sterilization → cooling → finished product.

[0003] Usually after completing the above steps, quick freezing is usually performed to facilitate the long-term storage of corn juice. It takes a certain process for the corn puree to change from room temperature to frozen state. Using conventional freezing methods, the temperature of the corn puree needs to be cooled to about zero degrees before freezing can be completed. In the process of cooling the corn puree from room temperature to zero degrees, the temperature inside the freezing equipment will increase to a certain extent, reducing the efficiency of the subsequent freezing process. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the utility model provides a device for quickly freezing fresh corn puree, which solves the technical problem of low freezing efficiency of corn puree.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include:

[0008] The utility model embodiment provides a device for quickly freezing fresh corn puree, including a freezing cabinet body, wherein a cooling chamber and a freezing chamber are provided inside the freezing cabinet body, the cooling chamber is located on the upper side of the freezing chamber, the freezing cabinet body is vertically provided with a spiral cooling pipe in the cooling chamber, the lower end of the cooling pipe extends into the freezing chamber, the freezing cabinet body is provided with a cold air fan that blows air vertically upward at the bottom of the cooling chamber, the freezing cabinet body is provided with a feeding funnel that is connected to the cooling pipe and into which corn puree is poured, and the freezing cabinet body is provided with a freezing drawer in the freezing chamber for receiving the corn puree that flows out after being cooled by the cooling pipe.

[0009] The utility model provides a device for quickly freezing fresh corn puree. When the freezing device is used, the corn puree is directly poured into a feed funnel, and the corn puree enters the cooling tube along the feed funnel. At this time, a cold air fan blows air upward. During the process of the corn puree flowing down the cooling tube, the cold air blown by the cold air fan will cool the cooling tube and the corn puree inside, so that the temperature of the corn puree drops sharply when it flows out along the cooling tube. At this time, the corn puree can be quickly frozen after flowing into the freezing drawer, thereby improving the freezing efficiency.

[0010] Optionally, a plurality of cooling fins are evenly arranged horizontally at an upper end of the cold air fan, the cooling fins are vertically arranged, and gaps for vertical air flow are formed between adjacent cooling fins.

[0011] By arranging multiple cooling fins at the upper end of the cold air fan, gaps are formed between adjacent cooling fins. After the air blown out by the cold air fan is cooled by the cooling fins, it can carry more heat after blowing through the cooling tube, thereby achieving a better cooling effect, thereby further improving the subsequent freezing effect.

[0012] Optionally, an air outlet connected to the cooling chamber is provided on the top of the freezing cabinet body, and the air outlet is inclined toward the feeding funnel.

[0013] By opening an air outlet on the top of the freezer body, the air blown out by the cold air fan can be blown out along the air outlet. At the same time, the temperature of the air blown out along the air outlet is still lower than the external temperature of the refrigeration device. At this time, the air outlet is set to be inclined toward the feed funnel, so as to cool the corn puree in the feed funnel, thereby further improving the effect of subsequent freezing.

[0014] Optionally, the freezer cabinet is provided with two one-way sealing films at the air outlet, the two one-way sealing films abut against each other to seal the air outlet, and the two one-way sealing films are separated by air blowing in the cooling chamber to open the air outlet.

[0015] By arranging two one-way sealing films at the air outlet, the two one-way sealing films abut against each other when not subjected to external force, and the air outlet is blocked at this time, so that the cooling chamber does not exchange heat with the outside; when the cold air fan in the cooling chamber is working, the two one-way sealing films are blown open. This solution enables the cooling chamber to better cool the cooling tube and corn puree, thereby improving the subsequent freezing efficiency.

[0016] Optionally, the vertical cross-section of the cooling tube is flat.

[0017] By arranging the cooling tube to have a flat cross section, the heat of the corn puree flowing in the cooling tube can be transferred to the surface of the cooling tube more quickly, thereby improving the cooling efficiency of the corn puree.

[0018] Optionally, a partition plate for cutting off the cooling tube is provided at a side end of the freezing cabinet body so as to slide horizontally between the cooling chamber and the freezing chamber.

[0019] By setting a partition plate for horizontal sliding at the side end of the freezer body, when the cooling process is completed and ready to be fully frozen, the cooling chamber and the freezing chamber can be completely separated by the partition plate, reducing the probability of heat exchange, thereby better freezing and improving freezing efficiency.

[0020] Optionally, there are multiple freezer drawers arranged in a vertical direction, and the multiple freezer drawers are horizontally slidably connected to the freezer cavity of the freezer body. The freezer body divides the freezer cavity into multiple slots for the freezer drawers to slide into, and when the freezer drawer partially slides out of the slot, it corresponds to the lower end of the cooling tube.

[0021] By providing multiple freezing drawers that are horizontally slidably connected to the freezing chamber, and each freezing drawer is slidably inserted into a slot, when corn puree flows down along the bottom of the cooling tube, the freezing drawer can be partially slid out of the slot in turn to receive the corn puree. When the freezing drawer is full of corn puree, it can be completely slid and inserted into the slot to complete batch freezing, thereby further improving the freezing efficiency.

[0022] Optionally, the cooling pipe includes an upper connecting pipe embedded in the freezing cabinet and connected to the feeding funnel, a lower connecting pipe embedded in the freezing cabinet and connecting the cooling chamber and the freezing chamber, and a spiral pipe detachably connected to the upper connecting pipe and the lower connecting pipe.

[0023] The cooling pipe is divided into three parts, wherein the spiral pipe is detachably connected to the upper connecting pipe and the lower connecting pipe, so that the spiral pipe can be removed and cleaned in time after use, which is more hygienic and safer.

[0024] Optionally, a flow limiting valve is provided on the lower connecting pipe.

[0025] By arranging a flow limiting valve on the lower connecting pipe, the flow rate of the corn puree along the spiral pipe can be adjusted, thereby adapting to the cooling of corn puree at different temperatures, which is more convenient.

[0026] (III) Beneficial effects

[0027] The beneficial effects of the utility model are as follows: the fresh corn puree quick freezing device of the utility model, when using the freezing device, the corn puree is directly poured into the feed funnel, and the corn puree enters the cooling tube along the feed funnel. At this time, the cold air fan blows air upward, and during the process of the corn puree flowing down along the cooling tube, the cold air blown by the cold air fan will cool the cooling tube and the corn puree inside, so that the temperature of the corn puree drops sharply when it flows out along the cooling tube.

[0034] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0035] The fresh corn puree quick freezing device proposed in the embodiment of the utility model, when using the freezing device, the corn puree is directly poured into the feed funnel, and the corn puree enters the cooling tube along the feed funnel. At this time, the cold air fan blows air upward, and during the process of the corn puree flowing down along the cooling tube, the cold air blown by the cold air fan will cool the cooling tube and the corn puree inside, so that the temperature of the corn puree drops sharply when it flows out along the cooling tube. At this time, the corn puree can be quickly frozen after flowing into the freezing drawer, thereby improving the freezing efficiency.

[0036] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0037] Reference Figure 1 and Figure 3 A device for rapidly freezing fresh corn puree comprises a freezing cabinet 1, wherein a cooling chamber 11 and a freezing chamber 12 are provided inside the freezing cabinet 1, wherein the cooling chamber 11 is located on the upper side of the freezing chamber 12, wherein a cooling pipe 2 in a spiral shape is vertically arranged in the cooling chamber 11 of the freezing cabinet 1, wherein the lower end of the cooling pipe 2 extends into the freezing chamber 12, wherein a feeding funnel 3 connected to the cooling pipe 2 and into which corn puree is poured is arranged on the top of the freezing cabinet 1, and a freezing drawer 4 is arranged in the freezing chamber 12 of the freezing cabinet 1 for receiving the corn puree flowing out after being cooled by the cooling pipe 2.

[0038] See also Figure 2 and Figure 3 The freezing cabinet 1 has a cold air fan 13 fixed horizontally at the bottom of the cooling chamber 11 by bolts. The back of the freezing cabinet 1 is provided with a plurality of air inlets 14 connected to the cooling chamber 11. The cold air fan 13 blows air vertically upward. The freezing cabinet 1 has a plurality of refrigeration fins 15 evenly arranged horizontally on the upper side of the cold air fan 13. The refrigeration fins 15 are vertically arranged, and gaps for vertical air flow are formed between adjacent refrigeration fins 15. The corn puree enters the cooling pipe 2 along the feeding funnel 3. At this time, the cold air fan 13 blows air upward. The temperature of the air decreases after passing through the refrigeration fins 15. When the corn puree flows down along the cooling pipe 2, the cold air blown by the cold air fan 13 will cool the cooling pipe 2 and the corn puree inside, so that the temperature of the corn puree drops sharply when it flows out along the cooling pipe 2. At this time, the corn puree can be quickly frozen after flowing into the freezing drawer 4.

[0039] An air outlet 16 connected to the cooling chamber 11 is provided on the top of the freezer cabinet 1, and the air outlet 16 is inclined toward the feed hopper 3. The temperature of the air blown out along the air outlet 16 is still lower than the external temperature of the refrigeration device. At this time, the air outlet 16 is arranged to be inclined toward the feed hopper 3, so as to cool the corn puree in the feed hopper 3.

[0040] Two one-way sealing films 17 are bonded to the air outlet 16 of the freezer cabinet 1. When the two one-way sealing films 17 are not subjected to external force, they abut against each other. At this time, the air outlet 16 is blocked, so that the cooling chamber 11 does not exchange heat with the outside. When the cooling fan 13 in the cooling chamber 11 is working, the two one-way sealing films 17 are blown open.

[0041] The cooling pipe 2 includes an upper connecting pipe 21 embedded in the freezing cabinet 1 and connected to the feeding funnel 3, a lower connecting pipe 22 embedded in the freezing cabinet 1 and connected to the cooling chamber 11 and the freezing chamber 12, and a spiral pipe 23 detachably connected to the upper connecting pipe 21 and the lower connecting pipe 22 through a silicone sleeve. The cooling pipe 2 is divided into three parts, wherein the spiral pipe 23 is detachably connected to the upper connecting pipe 21 and the lower connecting pipe 22, so that the spiral pipe 23 can be removed and cleaned in time after use. The vertical cross section is flat, and the heat of the corn puree flowing in the spiral pipe 23 can be transferred to the surface of the spiral pipe 23 faster to improve the cooling efficiency of the corn puree.

[0042] See also Figure 3 The lower connecting pipe 22 protrudes to the cooling chamber 11 and is provided with a limiting valve 24. The limiting valve 24 is used to adjust the flow rate of the corn puree along the spiral tube 23, thereby adapting to the cooling of corn puree at different temperatures.

[0043] See also Figure 2 and Figure 3 The side end of the freezing cabinet 1 is horizontally slidably inserted with a partition plate 25 for cutting off the cooling tube 2 between the cooling chamber 11 and the freezing chamber 12. When the cooling process is completed and the freezing state is ready, the cooling chamber 11 and the freezing chamber 12 can be completely separated by the partition plate 25, reducing the probability of heat exchange, so as to better perform freezing.

[0044] There are multiple freezer drawers 4 arranged in the vertical direction. The freezer cabinet 1 divides the freezer cavity 12 into multiple slots 121. Multiple freezer drawers 4 are horizontally slidably inserted into the slots 121 of the freezer cabinet 1. When the freezer drawer 4 is partially slid out of the slot 121, it corresponds to the lower end of the cooling tube 2. When corn puree flows down the bottom of the cooling tube 2, the freezer drawer 4 can be partially slid out of the slot 121 in sequence to receive the corn puree. When the freezer drawer 4 is full of corn puree, it is completely slid and inserted into the slot 121 to complete batch freezing.
