Description

Technical Field

[0001] The invention relates to the technical field of thawing equipment, and in particular to a food raw material freezing barrel thawing system. Background Art

[0002] Food slurry raw materials can generally be loaded in frozen barrels for easy batch transportation, such as cold fresh juice (lemon juice). During transportation, refrigerated trucks are generally used as transportation tools, and the temperature in the car is maintained at -18°C to ensure that the raw materials in the frozen barrels are normal. After being transported from the upstream factory to the downstream factory, they need to be thawed in time and then put into production and processing. When thawing, it is usually done by heating, such as a thawing box provided by the Chinese patent with the authorization announcement number CN214665894U, which includes a box body, a conductive water is contained in the box body, a heating pipe is arranged in the box body, heated water is passed through the heating pipe, a discharge port for entering and exiting the raw material barrel is opened on the top of the box body, a film for reducing heat loss is pasted on the discharge port, a lifting plate is arranged at the discharge port position in the box body, a turntable for placing the raw material barrel is arranged horizontally on a side wall of the lifting plate away from the bottom of the box body, the rotating shaft of the turntable is arranged in the vertical direction, a convex ring for limiting the raw material barrel is arranged on the turntable, a wiping piece for wiping the circumferential side wall of the raw material barrel is arranged on the outside of the discharge port of the box body, and a blow pipe for drying the raw material barrel is arranged on the outside of the discharge port of the box body.

A circulation pump 7 is provided between the circulation pool 6 and the pipeline assembly to pump the hot water in the circulation pool 6 into the pipe 12 system, and the hot water is sprayed out through the nozzle 2. The pipeline assembly may include a plurality of branch pipes 8, and the nozzle 2 is installed on the branch pipe 8. All branch pipes 8 are vertically arranged and arranged in rows. The freezing barrel 9 can be placed between the branch pipes 8 in adjacent rows, and the nozzle 2 can be on both sides of the branch pipe 8, so as to spray the hot water on the outer wall of the freezing barrel 9 on both sides; the filtering component is arranged at the bottom of the thawing chamber 1 and the hot water is sprayed out through the nozzle 2 and returned to the circulation pool 6 through the filtering component. The filtering component intercepts the stains washed down with the hot water to prevent it from entering the circulation pool 6.

[0028] In the above embodiment, more freezing barrels 9 can be placed in the thawing chamber 1, and the surface of the freezing barrel 9 is sprayed with hot water by multiple nozzles 2. The hot water flows downward along the outer wall of the freezing barrel 9 and passes through the filtering component and then returns to the circulation pool 6. In the process of flowing through the outer wall of the freezing barrel 9, the temperature of the freezing barrel 9 is increased, thereby achieving the purpose of thawing. The processing capacity is higher in the process, and the filtering component can block stains to avoid accumulation in the circulation pool 6, which is convenient for cleaning, thereby solving the problems of low thawing efficiency and easy accumulation of stains at the bottom of the box body in the prior art, which is inconvenient for cleaning; the temperature of the hot water will decrease after passing through the filtering component, and can be heated by the heating component to maintain it at 10-15°C. Specifically, the heating component includes a heating unit 10 and a heat exchange tube 11 arranged in the circulation pool 6, and the heating unit 10 is connected to the heat exchange tube 11 Then, the heating unit 10 and the circulation pool 6 can be arranged below the ground below the thawing chamber 1, the hot water can flow back to the circulation pool 6 by itself, and the circulation pump 7 is installed on the ground and extends to a higher place in the circulation pool 6 through the pumping pipe 12 to extract the hot water, and then pump it into the branch pipe 8 of the pipe assembly 12 to finally be sprayed out from the nozzle 2. Specifically, the pipe assembly also includes an inlet pipe 13 connected to the pumping pipe of the circulation pump 7, and a mounting pipe 14 connected to the inlet pipe 13. The inlet pipe 13 extends into the thawing chamber 1 and is connected to the mounting pipe 14. The mounting pipe 14 is located at the top of the thawing chamber 1, and the branch pipe 8 is connected to the mounting pipe 14. In particular, the inlet pipe 13 can be connected to a plurality of mounting pipes 14, so that the branch pipe 8 can be installed in a multi-row arrangement, and it is convenient to place the freezing barrel 9 between the rows for thawing operations.

[0029] like Figure 1 As shown, the heating unit 10 can be a heating device in the prior art, such as an electric heater, which heats the heat transfer oil, water, etc., and then circulates the heat transfer oil and water between the heat exchange tube 11 and the heating device through the provided pump body, thereby achieving the purpose of heating the hot water. However, whether to enable the heating component can be determined according to the specific situation. For example, in summer, the temperature of the hot water can be maintained at 10-15°C (or even higher) by itself, and no heating is required. The heat exchange tube 11 can be a spiral structure or other shapes; an inlet pipe 15 for replenishing hot water can also be provided on the circulation pool 6.

[0030] like Figure 1-4As shown, the filter assembly includes a cover plate 16 that is buckled on the bottom of the thawing chamber 1, a liquid receiving tank 17 is arranged below the cover plate 16, an inclined channel 18 is arranged between the liquid receiving tank 17 and the circulation pool 6, and the liquid receiving tank 17 is located at the higher end of the inclined channel 18, a plurality of first filter holes are arranged on the cover plate 16, the inclined channel 18 is inclined downward and connected to the middle section of the circulation pool 6, and the exchange hot water is refluxed, and then pumped into the pipe 12 system by the circulation pump 7 in the circulation pool 6 to form a circulation, the freezing barrel 9 is placed on the cover plate 16, and a support bar 19 is arranged below the cover plate 16, and the cover plate 16 is covered on the support bar 19, and the support bar 19 The bottom of the liquid receiving tank 17 is against the bottom of the liquid receiving tank 17 and a gap is provided to connect the spaces on both sides of the support strip 19, so that the hot water in the liquid receiving tank 17 can smoothly flow back to the circulation pool 6 through the inclined channel 18, and the cover plate 16 can also be opened to facilitate subsequent maintenance; in more detail, the filter assembly also includes a positioning ring 20, and a filter plate 21 located in the positioning ring 20, and a plurality of second filter holes are provided on the filter plate 21. The filter plate 21 is circular with an outer wall in sliding contact with the inner wall of the positioning ring 20, so that the filter plate 21 placed in the positioning ring 20 can cover the internal cross-section of the positioning ring 20, and the positioning ring The filter plate 20 and the filter plate 21 are both placed on the cover plate 16, and the inner diameter of the positioning ring 20 is larger than the outer diameter of the freezing barrel 9. The filter plate 21 is smoothly placed in the positioning ring 20, and the freezing barrel 9 is placed in the positioning ring 20 and supported on the filter plate 21. The exchange water flows downward along the outer wall of the freezing barrel 9 into the positioning ring 20, is filtered by the filter plate 21, and then passes downward through the cover plate 16 to the liquid receiving tank 17 below, that is, the filter plate 21 and the positioning ring 20 are in sliding contact so that there is a small gap between the two, which is convenient for the smooth removal and placement of the filter plate 21, and does not affect the normal filtering effect. Furthermore, in the positioning ring 2 0 is also fixedly connected with a first open ring 22, the upper end diameter of which is larger than the lower end diameter, so that the hot water can enter the first open ring 22 more smoothly and then be filtered by the filter plate 21 smoothly (in actual operation, there will be an outer convex ring (similar to an oil barrel for petroleum) arranged from top to bottom on the outer wall of the freezing barrel 9, so when the hot water flows downward, it may be affected by the outer wall of the freezing barrel 9 and diffuse outward, and the first open ring 22 can receive the expanded hot water to a greater extent, so as to intercept the stains on the filter plate 21 in the positioning ring 20 as much as possible, which is convenient for subsequent cleaning);

[0031] In further detail, one side of the filter plate 21 faces upward and is fixedly connected with a circular support block 23, a first support ring 24 and a second support ring 25 which are concentric therewith, and the other side faces upward and is fixedly connected with a third support ring 26, a fourth support ring 27 and a fifth support ring 28 which are concentric therewith, that is, the third support ring 26, the fourth support ring 27 and the fifth support ring 28 at the bottom are in contact with the cover plate 16, and the support block 23, the first support ring 24 and the second support ring 25 at the top are in contact with the bottom of the freezing barrel 9, so that space is left below and above the filter plate 21, and the upper The square space raises the bottom of the freezing barrel 9 to prevent contamination by substances, and the lower space ensures that the hot water can smoothly pass through the filter plate 21 and then pass through the cover plate 16 to achieve double filtration. The third support ring 26, the fourth support ring 27 and the fifth support ring 28 are respectively provided with a plurality of third filter holes, so that the lower space is in a connected state, and the hot water can enter the inner position and be filtered by the wider cover plate 16. Similarly, similar third filter holes can also be provided on the first support ring 24 and the second support ring 25, so that the hot water can be filtered by the wider filter plate 21.

[0032] like Figure 1 , 5 As shown in Figure 6, the freezing barrels 9 in the thawing chamber 1 can be stacked, thereby further increasing the processing capacity and achieving higher processing efficiency. Specifically, when stacked, a second open ring 29 can be placed on the top of the freezing barrel 9 in the lower layer. The bottom of the second open ring 29 is fixedly connected with a backing plate 30, and the top opening of the second open ring 29 is larger. The backing plate 30 can cover the top surface of the freezing barrel 9 and is also provided with a plurality of leakage holes 31 surrounding the freezing barrel 9. In this way, the exchange water flowing downward from the top can also enter the second open ring 29 more smoothly and pass through the leakage holes 31. Then it continues to flow downward. In a more detailed scheme, a second filter screen 32 can be provided at the leak hole 31 to filter the stains on the upper layer and reduce the filtering load below. Furthermore, the lower end of the second open ring 29 is also fixedly connected to a guide ring 33 that can surround the outside of the freezing barrel 9, and the guide ring 33 is separated from the outer wall of the freezing barrel 9, and the lower end of the guide ring 33 can also be close to the freezing barrel 9, that is, the lower end is a contracted structure, so that the hot water from the upper filter mesh can rush to the outer wall of the freezing barrel 9 and is not easy to diffuse outward.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it.
