Description

Technical Field

[0001] This utility model relates to the field of corn syrup processing technology, specifically a rapid heating device for corn syrup in starch production. Background Technology

[0002] Corn steep liquor is a byproduct obtained during the soaking of corn in the production of corn starch. It contains a variety of nutrients, including amino acids, organic acids, soluble sugars, vitamins, and metal salts. It is an important raw material in culture media for the production of antibiotics and other products, providing a natural organic nitrogen source for microbial growth. Due to its low price and rich nutritional content, it is widely used in industrial microbial fermentation.

[0003] Before the crushing process in starch processing, corn needs to be soaked. The quality of soaking directly affects the crushing effect in the next process. The quality of soaking cannot be observed directly with the naked eye. When the soaking is incomplete, the corn pulp after crushing will contain a large number of granular corn particles, resulting in too many impurities in the corn pulp. If the soaking time is too long, it will affect the production efficiency of corn pulp. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rapid heating device for corn syrup in starch production, which has the advantage of facilitating the processing of corn syrup and avoiding the cumbersome problem of soaking corn.

[0010] This utility model provides a rapid heating device for corn slurry in starch production, which has the following beneficial effects:

[0011] (1) The corn syrup rapid heating device in starch production drives the first servo motor to drive the pulping plate to rotate slowly to stir the corn, ensuring that it is heated evenly during soaking. The rapidly rotating pulping plate crushes and pulps the corn, and the corn syrup enters the bottom of the filter plate through the filter plate, while large particle fragments will remain above the filter plate to continue to be crushed, ensuring that the corn syrup is thoroughly stirred. At the same time, the rotating stirring plate can stir the corn syrup to enhance the preheating effect.

[0012] (2) The corn syrup rapid heating device in starch production drives the second servo motor to rotate the spiral blades to transport the corn syrup to the discharge pipe. Since the transmission tank is set in an inclined position, the water in the corn syrup can be collected at the bottom of the transmission tank and discharged through the arc-shaped filter screen into the water outlet pipe. This removes a large amount of water from the corn syrup and ensures the purity of the corn syrup. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-4 A rapid heating device for corn slurry in starch production includes a main board 1. A mixing tank 101 and a transfer tank 102 are fixedly connected to the top two sides of the main board 1, respectively. A mixing and pulping assembly 2 is installed inside the mixing tank 101 for processing corn. A transfer assembly 3 is installed on the inner wall of the transfer tank 102 for transferring corn slurry. A heating assembly 4 is installed on the top of the main board 1 for heating the mixing tank 101 and the transfer tank 102. The device also includes:

[0020] The mixing and pulping assembly 2 includes a filter plate 201, which is slidably installed in the inner cavity of the mixing tank 101. A spring 202 is fixedly connected between the filter plate 201 and the mixing tank 101. A first servo motor 203 is fixedly connected to the top of the mixing tank 101. A first rotating shaft 204 is fixedly connected to the output end of the first servo motor 203, and the first rotating shaft 204 passes through the filter plate 201. A pulping plate 205 is fixedly connected to the side wall of the first rotating shaft 204 above the filter plate 201, and a mixing plate 206 is fixedly connected to the side wall of the first rotating shaft 204 below the filter plate 201.

[0021] A connecting pipe 207 is fixedly connected between the bottom of the mixing tank 101 and the transfer tank 102, and a control device 208 is fixedly connected to the side wall of the connecting pipe 207.

[0022] It should be noted that: when corn is placed on top of the filter plate 201 in the inner cavity of the mixing tank 101 for soaking, the heating component 4 can be used to preheat the corn. At this time, the first servo motor 203 can be driven to drive the first rotating shaft 204. The first rotating shaft 204 drives the pulping plate 205 to rotate slowly to stir the corn, ensuring that it is heated evenly during the soaking process. After soaking, the rapidly rotating pulping plate 205 is used to crush and pulp the corn. At this time, under the elastic force of the spring 202, the filter plate 201 vibrates, increasing the speed of the corn pulp through the filter plate 201 and allowing it to enter below the filter plate 201. At the same time, the rotating stirring plate 206 can stir the corn pulp. At this time, the heating component 4 can preheat the corn pulp. After pulping is completed, the control device 208 is used to make the corn pulp enter the inner cavity of the transfer tank 102 through the connecting pipe 207.

[0023] Reference Figures 1-4 The transmission component 3 includes a second servo motor 301, which is fixedly installed on the side wall of the transmission barrel 102, and the output end of the second servo motor 301 is fixedly connected to a second rotating shaft 302.

[0024] The second rotating shaft 302 has a spiral blade 303 fixedly connected to its side wall, the conveying barrel 102 is set in an inclined position, and the bottom of the conveying barrel 102 is fixedly connected to a discharge pipe 304.

[0025] An arc-shaped filter screen 305 is fixedly connected to the inner wall of the transfer tank 102, and a water outlet pipe 306 is fixedly connected to the bottom of the transfer tank 102 below the arc-shaped filter screen 305.

[0026] It should be noted that: the second servo motor 301 drives the spiral blades 303 on the side wall of the second rotating shaft 302 to rotate, thereby conveying the corn slurry from the bottom of the transfer tank 102 to the discharge pipe 304 above. The heating component 4 can heat the corn slurry inside the transfer tank 102. Moreover, since the transfer tank 102 is set in an inclined position, the water in the corn slurry can accumulate at the bottom of the transfer tank 102 and enter the water outlet pipe 306 through the arc-shaped filter screen 305 for discharge, thereby removing a large amount of water from the corn slurry.

[0027] Reference Figures 1-4 The heating component 4 includes an exhaust gas filter box 401, which is fixedly installed on the top of the main board 1. A first air inlet pipe 402 is fixedly connected between the exhaust gas filter box 401 and the mixing tank 101.

[0028] A second air inlet pipe 403 is fixedly connected between the mixing tank 101 and the transfer tank 102, and a first spiral tube 404 is provided on the inner wall of the mixing tank 101.

[0029] The inner wall of the transfer tank 102 is provided with a second spiral tube 405, and the exhaust gas filter box 401, the mixing tank 101 and the transfer tank 102 are connected to each other. The top of the transfer tank 102 is fixedly connected with an exhaust pipe 406.

[0030] It should be noted that the exhaust gas filter box 401 can remove impurities from the high-temperature gas in the starch production process and then input it into the first spiral tube 404 inside the mixing tank 101 through the first air inlet pipe 402, thereby heating the mixing tank 101. The high-temperature gas in the first spiral tube 404 enters the second spiral tube 405 inside the transfer tank 102 through the second air inlet pipe 403 to heat the transferred corn slurry, and then is discharged through the exhaust pipe 406.

[0031] Operation method: The exhaust gas filter box 401 removes impurities from the high-temperature gas in the starch production process and then inputs it into the first spiral tube 404 inside the mixing tank 101 through the first air inlet pipe 402 to heat the mixing tank 101, thereby heating the soaked corn. Then, the first servo motor 203 drives the first rotating shaft 204, which drives the pulping plate 205 to rotate slowly to stir the corn and ensure that it is heated evenly during soaking. After soaking, the rapidly rotating pulping plate 205 is used to crush and pulp the corn. At this time, under the elastic force of the spring 202, the filter plate 201 vibrates, which increases the speed of the corn pulp through the filter plate 201 and makes it enter the bottom of the filter plate 201. At the same time, the rotating stirring plate 206 can stir the corn pulp. At this time, the gas inside the first spiral tube 404 can preheat the corn pulp. After pulping is completed, the control device 208 is used to make the corn pulp enter the inner cavity of the transfer tank 102 through the connecting pipe 207.

[0032] The second servo motor 301 drives the spiral blades 303 on the side wall of the second rotating shaft 302 to rotate, thereby conveying the corn slurry from the bottom of the transfer tank 102 to the discharge pipe 304 above. Since the transfer tank 102 is set at an inclination, the water in the corn slurry can accumulate at the bottom of the transfer tank 102 and enter the water outlet pipe 306 through the arc-shaped filter screen 305 to be discharged, thereby removing a large amount of water from the corn slurry. The high-temperature gas in the first spiral tube 404 enters the second spiral tube 405 inside the cavity of the transfer tank 102 through the second air inlet pipe 403 to heat the conveyed corn slurry, and then discharges through the air outlet pipe 406.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
