Description

Technical Field

[0001] This utility model relates to the field of zongzi cooling technology, specifically to a cooling device for high-dietary-fiber zongzi. Background Technology

[0002] With the popularization of healthy eating concepts, high-fiber zongzi, as an improved health food, has gradually gained market favor. Its ingredients usually include oats, buckwheat, quinoa, beans, and vegetable fiber, which are rich in dietary fiber. Compared with traditional glutinous rice zongzi, it has advantages such as low glycemic index, high satiety, and promotion of intestinal peristalsis. At present, the commonly used cooling methods in zongzi production mainly include natural cooling, forced air cooling, water cooling, and vacuum cooling, but they have obvious shortcomings when processing high-fiber zongzi.

[0003] For example, application number CN201922398176.8 describes a cooling device for producing zongzi (sticky rice dumplings), comprising: a cooling box, a sealed door fixedly installed on the front side of the cooling box, a control box fixedly installed on the left outer wall of the cooling box, a vacuum pump fixedly installed on the front top of the cooling box, the air inlet of the vacuum pump being connected to an adsorption box via a pipe, a vacuum chamber provided on the front inside the cooling box, several placement racks provided inside the vacuum chamber, and a condensation chamber provided on the rear inside the cooling box.

[0004] The above cases will result in collapse or deformation when dealing with high-fiber zongzi. This is because the high fiber content and low proportion of glutinous rice in these zongzi lead to a decrease in overall stickiness and weaker structural stability. Especially after heat processing (such as steaming or boiling), the texture of the zongzi is loose and it is prone to deformation or collapse due to external forces or environmental changes. Utility Model Content

[0005] Given the above cases, when dealing with high-fiber zongzi, phenomena such as collapse or deformation may occur. This is because the high fiber content and low proportion of glutinous rice in these zongzi result in decreased overall stickiness and weaker structural stability. Especially after heat processing (such as steaming or boiling), the texture of the zongzi is relatively loose, making it prone to deformation and collapse due to external forces or environmental changes.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a cooling device for high dietary fiber zongzi (sticky rice dumplings), comprising: a cooling box and a rectangular placement plate, wherein several rectangular placement plates are arranged in an array inside the cooling box, and several rectangular mounting grooves are also provided on the upper surface of the rectangular placement plates, and rectangular guide strips are also provided on the short vertical surfaces on both sides of the rectangular placement plates, and a shaping mold is fixedly installed on the upper surface of the rectangular placement plates, the shaping mold comprising: a rectangular mounting plate, a circular groove is provided through the upper surface of the rectangular mounting plate, a conical shaping structure is also installed on the circular groove, and a rectangular moving groove is opened on the upper surface of the rectangular mounting plate, and a T-shaped moving block is slidably connected to the inner ring of the rectangular moving groove.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] The present invention will be further described below with reference to the embodiments. Example 1:

[0024] Reference Figure 1-5 This is the first embodiment of the present invention, which discloses a cooling device for high dietary fiber zongzi (sticky rice dumplings), including: a cooling box 1 and a rectangular placement plate 2. Several rectangular placement plates 2 are arranged in an array inside the cooling box 1. Several rectangular mounting grooves are also provided on the upper surface of the rectangular placement plate 2. Rectangular guide strips are also provided on the short vertical surfaces on both sides of the rectangular placement plate 2. A shaping mold 3 is fixedly installed on the upper surface of the rectangular placement plate 2. The shaping mold 3 includes: a rectangular mounting plate 4. A circular groove is provided through the upper surface of the rectangular mounting plate 4. A conical shaping structure 5 is also installed on the circular groove. A rectangular moving groove 6 is opened on the upper surface of the rectangular mounting plate 4. A T-shaped moving block 7 is slidably connected to the inner ring of the rectangular moving groove 6. A round rod is provided on the lower surface of the T-shaped moving block 7.

[0025] A mounting rod 8 is provided on the upper surface of the T-shaped moving block 7. A rectangular plate 9 is fixedly installed on the vertical surface of the mounting rod 8. A rectangular support plate is also installed on the vertical surface of the mounting rod 8. A mounting groove is provided through the vertical surface inside the rectangular moving groove 6. A rectangular storage sleeve 10 is slidably connected to the bottom surface of the mounting groove. An inclined block 11 is slidably connected to the vertical surface of the rectangular storage sleeve 10. A spring piece is provided inside the rectangular storage sleeve 10, and one end of the spring piece contacts the inclined block 11.

[0026] The conical shaping structure 5 includes: a mounting ring 13, an inclined ring 14 fixedly mounted on the lower surface of the mounting ring 13, an arc-shaped connecting rod 15 provided on the lower surface of the inclined ring 14, several arc-shaped connecting rods 15 connected to the same docking ring 16 on their lower surfaces, an arc-shaped connecting rod 15 also provided on the lower surface of the docking ring 16, a limiting ring fixedly connected to the lower surface of the arc-shaped connecting rod 15, and several protective strips 17 provided on the inner ring of the inclined ring 14.

[0027] When using the rice dumpling, first quickly place the pointed end of the rice dumpling into the inclined ring 14. The lower surface of the inclined ring 14 is provided with an arc-shaped connecting rod 15, and the lower surfaces of several arc-shaped connecting rods 15 are connected to the same docking ring 16. The lower surface of the docking ring 16 is also provided with an arc-shaped connecting rod 15, and the lower surface of the arc-shaped connecting rod 15 is fixedly connected to a limiting ring. The inner ring of the inclined ring 14 is provided with several protective strips 17. The function of the protective strips 17 is to ensure that the inclined surface of the rice dumpling has reserved space, preventing the inclined surface of the rice dumpling from having large-area contact with the inclined surface of the inclined ring 14 and the inclined surface of the docking ring 16, which would lead to uneven cooling. After the rice dumpling is placed, you need to pinch the two pointed corners at the top of the rice dumpling with your left hand and then lift it slightly.

[0028] Then, use two fingers of your right hand to bring the pair of T-shaped moving blocks 7 closer together. Because each of the T-shaped moving blocks 7 has a round rod on its lower surface, and the rectangular storage sleeve 10 is slidably connected to the inclined block 11 on its vertical surface, and the rectangular storage sleeve 10 has a spring piece inside. One end of the spring piece contacts the inclined block 11. When the round rod contacts the inclined block 11, the inclined block 11 will retract due to the pushing force. After the round rod passes through, the inclined block 11 will rebound due to the rebound force of the spring piece, so that the rectangular plate 9 and the rectangular support plate can support the rice dumpling.

[0029] High-fiber zongzi (sticky rice dumplings) have a high fiber content and a lower proportion of glutinous rice, resulting in reduced overall stickiness and weaker structural stability. Therefore, the vacuum cooling process in this case will be modified to address the issue of high-fiber zongzi by employing a "step-by-step pressure reduction" approach to avoid sudden pressure drops. The first stage involves reducing the pressure to 10-15 kPa within 3-5 minutes (maintaining this pressure for 5-8 minutes) to allow surface moisture to evaporate slowly and achieve initial cooling. The second stage involves reducing the pressure to 3-5 kPa within 5-8 minutes (maintaining this pressure for 10-15 minutes) to accelerate internal heat conduction. The third stage involves adjusting the pressure based on the core temperature, ultimately stabilizing the vacuum level at 1-3 kPa (total cooling time controlled within 30-40 minutes, ensuring the core temperature drops from above 90℃ to below 25℃). The more moisture lost during vacuum cooling, the more significant the shrinkage in the zongzi's volume (especially in the glutinous rice structure), which can easily lead to collapse. The total weight loss rate needs to be controlled within 1%-3% (i.e., 100g of zongzi loses 1-3g after cooling). Weigh the zongzi before and after cooling. If the weight loss exceeds 3%, the vacuum time in the third stage needs to be shortened or the final vacuum level needs to be increased (e.g., from 1kPa to 2-3kPa to slow down the evaporation rate). Example 2:

[0030] Reference Figure 3 and 4This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a rectangular cover is inserted into the vertical surface of the rectangular storage sleeve 10 away from the inclined block 11, and an L-shaped plate 18 is fixedly connected to the vertical surface of the rectangular cover. An insertion interface is provided through the vertical surface of the L-shaped plate 18, and a limiting rod 19 is inserted into the inner ring of the insertion interface. A mating groove 20 is provided at the intersection of the limiting rod 19 and the rectangular mounting plate 4. A distance display ruler 21 is also installed on the upper surface of the rectangular mounting plate 4.

[0031] When using the device, if it is necessary to adjust the distance between the T-shaped moving blocks 7, first pull out the limiting rod 19 by hand. This is because the rectangular storage sleeve 10 is inserted into the vertical surface away from the inclined block 11, and the vertical surface of the rectangular cover is fixedly connected to the L-shaped plate 18. The vertical surface of the L-shaped plate 18 is fixedly connected to the indicator arrow. Then, the position of the rectangular storage sleeve 10 can be adjusted. After the movement is completed, the limiting rod 19 can be inserted back in.

[0032] The remaining structure is the same as that in Example 1.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
