Description

Technical Field

[0001] The utility model relates to the technical field of dairy product processing, in particular to a low-temperature odor removal device for dairy products. Background Art

[0002] Dairy products refer to various products made from fresh cow (sheep) milk and its products as the main raw materials through a series of processing treatments, also called dairy products. Dairy products need to be deodorized during processing. The "flash evaporation and degassing device for multiple deodorization of goat milk" disclosed in the publication number "CN221241543U" has solved the technical disadvantages of large-scale accumulation of steam, which makes it easy for steam to re-mix with goat milk, and the liquid after steam condensation flows back into the goat milk along the inner wall. However, in actual use, deodorization devices with similar structures still have many defects. For example, when in use, most of them preheat the dairy products through an electric heating mechanism, and do not have the function of recycling the high-temperature steam containing odor after flash evaporation, which leads to the loss and waste of excess heat energy during operation of the device, and increases the cost of the device for deodorization of dairy products. For this reason, we have designed a low-temperature deodorization device for dairy products to solve the above problems. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a low-temperature deodorizing device for dairy products, which solves the problem that the high-temperature steam containing the odor cannot be recycled after deodorizing, resulting in the device consuming additional electricity during preheating, which increases the deodorizing cost.

Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-5 The present invention provides a technical solution: a low-temperature deodorization device for dairy products, including a flash evaporation mechanism 1 and a preheating mechanism 2 assembled on one side of the flash evaporation mechanism 1, and a deodorization mechanism 3 assembled on the top of the flash evaporation mechanism 1. The flash evaporation mechanism 1 includes a flash evaporation tank 101. A closing cover 102 is fixedly installed on the top of the flash evaporation tank 101. A heating rod 108 is fixedly installed below the interior of the flash evaporation tank 101. An inlet pipe 104 is fixedly installed on one side of the flash evaporation tank 101. An extractor 205 is fixedly installed on one side of the top of the closing cover 102. The preheating mechanism 2 includes a preheating tank 201. A sealing cover 203 is fixedly installed on the top of the preheating tank 201. A heat conduction pipe 204 is fixedly installed on one side of the top of the sealing cover 203. One end of the heat conduction pipe 204 is fixedly connected to the top of the extractor 205. A spiral heating pipe 206 connected to the bottom of the heat conduction pipe 204 is fixedly installed inside the preheating tank 201. The deodorization mechanism 3 includes a deodorization pipe 301. An extraction hood 302 is fixedly installed at the bottom on one side of the deodorization pipe 301. A fan pipe 303 is fixedly installed on the deodorization pipe 301. An electric push rod 304 is fixedly installed at the top on one side of the deodorization pipe 301. The output end of the electric push rod 304 extends into the interior of the extraction hood 302 and is fixedly installed with a sealing seat 305.

[0022] Based on the above-mentioned structural setting, the low-temperature deodorization device for dairy products is composed of a flash evaporation mechanism 1, a preheating mechanism 2 and a deodorization mechanism 3, wherein the dairy product is injected into the interior of the flash tank 101 through the inlet pipe 104, the heating rod 108 can heat the dairy product in the flash tank 101, the closing cover 102 can close and seal the top of the flash tank 101, and the dairy product can be evaporated at a lower temperature by reducing the pressure inside the flash tank 101, and the odor of the dairy product can be stripped off with the evaporated steam, thereby realizing the deodorization of the dairy product at a low temperature, the extractor 205 can extract the steam in the flash tank 101, and conduct it to the interior of the spiral heating tube 206 through the heat conduction tube 204, the spiral heating tube 206 is installed in the preheating tank 201, and the preheating tank 201 can store the dairy product to be deodorized, so that the deodorized high-temperature steam and the spiral heating tube can be used to remove the odor of the dairy product. The rotary heating tube 206 can preheat the dairy products to be deodorized. The preheating of the dairy products facilitates the subsequent deodorization of the dairy products by the flash tank 101, thereby improving the efficiency and quality of the flash tank 101 in deodorizing the dairy products. In addition, the heat loss waste during the operation of the device is reduced by recycling the deodorized steam. The extraction hood 302 is fixedly installed on the top of the closing cover 102. The electric push rod 304 can move the sealing seat 305 to the inside of the extraction hood 302 and block it by contraction, thereby increasing the overall sealing of the flash tank 101 during operation. When too much deodorized steam accumulates inside the flash tank 101, the electric push rod 304 can extend to lower the sealing seat 305, so that the extraction hood 302 can be opened, and the fan pipe 303 on the deodorizing pipe 301 can discharge the deodorizing steam inside the flash tank 101, thereby completing the deodorization of the dairy products in the flash tank 101.

[0023] Furthermore, a stirring motor 105 is fixedly installed at the bottom of the flash tank 101, and a stirring paddle 106 is fixedly installed at the output end of the stirring motor 105 through the flash tank 101. The stirring motor 105 drives the stirring paddle 106 to rotate in the flash tank 101 to stir and mix the dairy product, thereby increasing the uniformity of the device in flash steaming and deodorizing the dairy product.

[0024] Furthermore, a raw liquid pipe 202 is fixedly installed on one side of the preheating tank 201, and a drain pipe 207 used in conjunction with the inlet pipe 104 is fixedly installed on the other side of the preheating tank 201. The raw liquid pipe 202 is connected to an external dairy product pipeline, so that the dairy product to be deodorized can enter the interior of the preheating tank 201. The drain pipe 207 is connected to the inlet pipe 104, and the dairy product preheated by the preheating tank 201 can be discharged into the interior of the flash tank 101 through the drain pipe 207.

[0025] Further, multiple groups of sealing rings 306 are fixedly installed on the outer wall of the sealing seat 305. Among them, the sealing ring 306 increases the sealing performance of the sealing seat 305 when the extraction hood 302 is closed.

[0026] Further, a vacuum pump 103 is fixedly installed on the other side of the flash evaporation tank 101, and a pressure gauge 109 that is used in cooperation with the vacuum pump 103 is fixedly installed on the front of the flash evaporation tank 101. Among them, the vacuum pump 103 can evacuate the inside of the flash evaporation tank 101. By evacuating the inside of the flash evaporation tank 101, the pressure inside it can be reduced, thereby facilitating the device to perform the deodorization treatment on dairy products in a low-temperature state. The pressure gauge 109 can measure and display the pressure inside the flash evaporation tank 101.

[0027] Further, a discharge valve 107 is fixedly installed on the other side of the bottom of the flash evaporation tank 101. Among them, the discharge valve 107 can discharge the dairy products after the deodorization in the flash evaporation tank 101, thereby facilitating the device to perform the deodorization treatment on subsequent dairy products.
