Description

Technical Field

[0001] This utility model relates to the field of nut beverage processing equipment technology, and in particular to a rapid cooling device for nuts after roasting. Background Technology

[0002] In the production and processing of peanut milk, peanuts not only need to be roasted to develop their unique aroma, but also need to have excess moisture removed. This extends shelf life and facilitates secondary processing such as crushing and grinding. However, if the peanuts are not cooled promptly after roasting, the high-temperature, humid gases released during roasting will cause them to become damp again, affecting their crisp texture and making them unsuitable for long-term storage. Existing cooling methods mostly involve manual spreading, supplemented by simple air cooling with fans. This method is not only labor-intensive, but also cumbersome in spreading and collecting the peanuts, and has low cooling efficiency, making it unsuitable for large-scale production. Therefore, there is an urgent need for a rapid cooling device for nuts that can achieve efficient and uniform cooling and automatically sort and distribute the peanuts. Summary of the Invention

The receiving plate 8 and the guide plate 9 are in relative positions, and the bottom of the guide plate 9 cooperates with the feeding end of the conveying structure.

[0028] In a preferred embodiment, the conveyor belt 11 is provided with side baffles 12 on both sides.

[0029] In a preferred embodiment, the material handling structure 16 includes an electric telescopic rod 18 disposed on the top of the inner wall of the cooling box 1, the output end of the electric telescopic rod 18 is provided with a flat plate 19, and the feeding end of the flat plate 19 is provided with a feeding arc plate 20.

[0030] In a preferred embodiment, the top of the cooling box 1 is provided with a breathable mesh cover 4.

[0031] In a preferred embodiment, the bulk material structure 17 includes a reciprocating rod 21, which engages with positioning holes 5 symmetrically arranged on the cooling box 1. The reciprocating rod 21 is provided with multiple baffles 22 that engage with the surface layer of the conveyor belt 11. One end of the reciprocating rod 21 is provided with a limiting plate 23, which is connected to the outer wall of the cooling box 1 through multiple elastic elements 24. The other end of the reciprocating rod 21 is provided with an adjusting frame 25, which engages with an adjusting cam 26.

[0032] In a preferred embodiment, the positioning hole 5 is provided with multiple sets of support balls 6 that slide in cooperation with the reciprocating rod 21.

[0033] Example 2:

[0034] like Figure 1 and 4 In the middle, the cooling box 1 is made of 304 stainless steel, with a length of 3m × width of 1.2m × height of 0.8m. The conveyor belt 11 is made of food-grade polyester mesh with a mesh diameter of 2mm. It is driven by a 1.5kW first motor 13, with an adjustable linear speed range of 0.3-1.2m / min. Eight sets of axial flow cooling fans 15 are evenly arranged at a 30° tilt angle, with a single unit air volume of 200m³ / h.

[0039] The working principle of this utility model is as follows:

[0040] After roasting, the nuts (temperature 80-100℃) enter through the wide-mouth feed chute 7. The V-shaped channel formed by the receiving plate 8 and the guide plate 9 controls the dropping speed at 0.5-0.8kg / s to avoid impact and accumulation.

[0041] The conveyor belt 11 conveys nuts at a speed of 0.5-8m / min. After being guided by the feed arc plate 20, the nuts are flattened by the flat plate 19 to avoid stacking.

[0042] The bottom four cooling fans start at 15, with an airflow temperature of 25±2℃ and a wind speed of 3m / s;

[0043] The second motor 29 drives the adjusting cam 26 to rotate, which in turn drives the reciprocating rod 21 to perform horizontal reciprocating motion through the adjusting frame 25;

[0044] The turner plate 22 flips the material at a frequency of 6-10 times / minute, and the elastic element 24 provides a 5N buffer force to prevent mechanical impact.

[0045] After being repeatedly turned and cooled at the end of the conveyor, the material's temperature drops below 30℃, and its water activity Aw ≤ 0.65. Finally, it is discharged through discharge chute 3. The entire cooling process takes 4-6 minutes, which is more than 50% shorter than traditional methods.

[0046] The beneficial effects of this utility model are: efficient air cooling during the conveying process, and the upward air flow can quickly remove the humid and hot water vapor surrounding the roasted nuts; during the conveying process, the material is laid flat to avoid stacking, and the air cooling is comprehensive and uniform. Combined with the back-and-forth material feeding, the cooling efficiency is further improved; the overall structure of the device is simple and reasonable, and it is flexible and convenient to use, reducing manpower consumption and being practical and stable.
