Description
Intelligent fresh milk supply station with rapid cooling and preservation This invention relates to an intelligent fresh milk supply station with rapid cooling and preservation capabilities. The main feature is that when fresh milk is being replenished, its temperature can be reduced from 4°C to 2°C within 60 seconds, achieving rapid cooling and preservation. The cooling effect is further transferred to the central depth of the cold storage compartment through the combined cooling riser and cooling fins, ensuring that the fresh milk is preserved effectively in every central depth location. Note: As modern people's living standards improve, diet has become significantly more important. Modern people's interest in and consumption of fresh milk has also increased considerably, with fresh milk being a favorite beverage for many. Currently, fresh milk is mainly sold in sealed boxes or cans. However, when users need large quantities of fresh milk for cooking or other purposes, purchasing commercially available fresh milk results in the waste of numerous packaging boxes or bottles, causing inconvenience to consumers and being environmentally unfriendly. This reflects consumers' strong desire and is a goal and direction that related businesses must strive to achieve through research and development. In view of this, the inventor of this case recently created an invention in the Republic of China, with application number "112208486". The "intelligent fresh milk supply station" mainly comprises a machine with an internal control unit. The machine includes at least one refrigeration compartment, with a refrigeration compressor positioned opposite it. A fresh milk beverage storage box containing fresh milk beverages is located within the refrigeration compartment. The storage box is connected to a conduit. A dispensing compartment is positioned relative to the storage box, and the conduit extends to the dispensing compartment. A sales and transaction human-machine interface is embedded in a suitable location on the machine's surface. The central processing unit electrically controls the machine. The fresh milk beverage storage box outputs the quantity of fresh milk beverages to the distribution room through a conduit; however, when fresh milk is stored inside the refrigerator of the conventional structure, the distance between the fresh milk in the central depth position and the cooling compressor is relatively far, so the fresh milk in the central depth position cannot be cooled evenly, which easily leads to spoilage. In order to improve the ability to ensure the overall freshness and guarantee the drinking quality of consumers when there is a large quantity of fresh milk that can be stored at a depth, the inventors of this invention have been constantly developing and improving. After detailed design and careful evaluation, the invention has finally achieved a truly progressive invention. That is, the main objective of this invention is to provide an intelligent fresh milk supply station with rapid cooling and preservation; the problem it seeks to solve is to overcome the problem that when fresh milk is stored in the refrigerator compartment of a conventional structure, the distance between the fresh milk in the central depth position and the cooling compressor is relatively far, so the central depth position of the fresh milk cannot be fully cooled, which easily leads to the spoilage of the fresh milk. Therefore, this invention utilizes an intelligent fresh milk supply station with rapid cooling and preservation capabilities. When fresh milk is being replenished, its temperature can be reduced from 4°C to 2°C within 60 seconds, achieving rapid cooling and preservation. This is achieved by using liquid nitrogen and ethylene glycol coolant inside the cooling riser, which are applied to the liquid nitrogen and ethylene glycol coolant through the compressor piping to create a synergistic cooling effect. Furthermore, the expansion cooling fins further transmit the cooling effect to the depth of the interior of the cold storage compartment and the surrounding area, ensuring that the fresh milk can be kept fresh and cold in every space, thus maintaining the freshness of the fresh milk raw materials and food hygiene. Please refer to Figures 1-8, which illustrate preferred embodiments of the intelligent fresh milk supply station with rapid cooling and preservation according to the present invention.

The full-fat dispensing chamber A1 is provided with a sealing door A2 and a handle A3 on the outside. The handle A3 is convenient for opening by hand, and the sealing door A2 can improve the hygiene and temperature retention of the machine. Two refrigeration and preservation modules 30 are respectively disposed in the whole milk refrigeration compartment A41 and the skim milk refrigeration compartment B41 of the machine 10, and are fixed to the bottom end surface A of the whole milk refrigeration compartment A41 and the skim milk refrigeration compartment B41. Each refrigeration and preservation module 30 comprises a stainless steel cooling riser 31 and a stainless steel cooling fin 37 arranged opposite to each other. The cooling riser 31 includes an outer tube 32, and an outer space 33 is formed inside the outer tube 32. An inner tube 34 is disposed inside the outer space 33, and an inner space 35 is disposed inside the inner tube 34. A sealing part 321 is provided on the periphery of the outer tube 32 relative to the periphery of the inner tube 34. A second interface 322 is provided on the sealing part 321 opposite to the outer space 33. The top of the inner tube 34 A first interface 341 is provided at the position opposite to the inner layer space 35, so that both the outer layer space 33 and the inner layer space 35 are sealed spaces. The bottom end of the cooling riser 31 is provided with a bottom end 36, which is welded to the bottom end face A of the whole milk refrigerator compartment A41 and the skim milk refrigerator compartment B41 by welding, and connects each compressor pipeline 60 to the inner layer space 35 inside the inner layer pipe 34. The welding position forms a welding point D respectively. In addition, the outer layer space 33 is filled with ethylene glycol coolant 40 (HOCH2—CH2OH) through the second interface 322. Ethylene glycol is a colorless and slightly viscous liquid with a boiling point of 4°C and a freezing point of -11.5°C. And the inner layer space 35 is filled with liquid nitrogen 50 (LN) through the first interface 341. 2), Liquid nitrogen 50 (LN) 2) It is an inert, colorless, odorless, non-corrosive, and non-flammable liquid, and liquid nitrogen 50 (LN) 2) It is a liquid obtained in an environment with extremely low temperatures; The liquid nitrogen 50 and the ethylene glycol coolant 40 are polar cooling substances. When the cooling is applied to the liquid nitrogen 50 and the ethylene glycol coolant 40 through the compressor pipeline 60, a synergistic cooling effect is generated, which can greatly reduce the consumption of electrical energy and keep the central depth position 70 of the fresh milk inside fresh. The cooling fin 37 is generally in the shape of a spiral plate. The center of the cooling fin 37 is longitudinally penetrated by a connecting inner edge 38. The connecting inner edge 38 is welded to the outer edge of the cooling riser 31. The surface of the spiral plate-shaped cooling fin 37 has a continuously extending spiral slope 39. The spiral slope 39 allows the fresh milk to flow down smoothly along the spiral slope 39 when the volume height decreases, without leaving residue on the surface. The cooling fin 37 has the characteristic of expanding the cooling to expand the cooling around the two cooling and preservation modules 30. The refrigeration and preservation module 30 utilizes the cooling effect of the ethylene glycol coolant 40 and the liquid nitrogen 50, and through the cooling fins 37, conducts the low temperature to the central depth position 70 inside the whole milk refrigerator compartment A41 and the skim milk refrigerator compartment B41. Normally, milk in the central depth position 70 inside the refrigerator compartment is less susceptible to cold conduction and thus less likely to achieve a preservation effect. However, this invention further utilizes the cooling fins 37 to conduct the cooling effect to the central depth position 70 inside the refrigerator compartment, ensuring that the milk achieves a preservation effect in every position, thereby reducing the possibility of bacterial growth. Please refer to Figure 7, which is a temperature-time curve for the rapid cooling and preservation of fresh milk according to the present invention. When fresh milk is replenished, the temperature of the fresh milk can be reduced from 4°C to 2°C within 60 seconds, so that the fresh milk achieves the effect of rapid cooling and preservation. The cooling effect is further conducted to the central depth position 70 of the refrigerator compartment by the combined cooling riser 31 and the cooling fins 37, so that the fresh milk can achieve the preservation effect in every position, thereby reducing the possibility of bacterial growth.
