Description

Technical Field

[0001] This utility model relates to a beverage sterilization and color-fixing device, belonging to the field of beverage production technology. Background Technology

[0002] Sterilization and color fixation are crucial steps in beverage production. Beverages contain nutrients such as carbohydrates, proteins, and vitamins, which are conducive to the growth and reproduction of microorganisms. To ensure the stability of the taste and flavor of beverages throughout their shelf life, sterilization is essential during production. Color fixation primarily refers to maintaining the original color of the beverage during processing. Color fixation is significant for enhancing the visual appeal and consumer acceptance of beverages.

[0003] However, existing beverage sterilization and color-fixing equipment consumes a lot of energy during operation, increasing production costs and easily damaging the original flavor substances and nutrients of beverages. Beverages will undergo browning reactions during prolonged heating, which will affect the color-fixing effect.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This invention addresses the shortcomings of the prior art by providing a beverage sterilization and color-fixing device. It sterilizes and fixes beverages by heating with steam and rapidly cools them with cooling water. This ensures that the beverages are fully sterilized and fixed in color while preventing browning due to excessive heating time. It has low energy consumption and good color-fixing effect.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] A beverage sterilization and color-fixing device includes a sterilization tank and a shell-and-tube heat exchanger. The bottom outlet of the sterilization tank is connected to one end of a sterilization feed pipe, and the other end of the sterilization feed pipe is connected to the tube-side inlet of the shell-and-tube heat exchanger. The tube-side outlet of the shell-and-tube heat exchanger is connected to one end of a sterilization reflux pipe, and the other end of the sterilization reflux pipe is connected to the reflux port of the sterilization tank. The shell-side inlet of the shell-and-tube heat exchanger is connected to a steam inlet pipe, and the shell-side outlet of the shell-and-tube heat exchanger is connected to a steam drain pipe. The shell-side outlet of the shell-and-tube heat exchanger is also connected to a cooling water inlet pipe, and the shell-side inlet of the shell-and-tube heat exchanger is also connected to a cooling water outlet pipe.

[0008] Furthermore, an air filter is installed on the top of the sterilization tank.

[0009] Furthermore, a circulation pump is installed on the sterilization feed pipe.

[0010] Furthermore, the sterilization feed pipe is connected to the raw liquid feed pipe, and the connection point is located on the pipeline between the circulating pump and the shell and tube heat exchanger.

[0011] Furthermore, the sterilization feed pipe is also connected to the finished product discharge pipe, and the connection point is located on the pipeline between the circulating pump and the shell and tube heat exchanger.

[0012] Furthermore, a compressed air inlet pipe is connected to the top of the inner cavity of the shell-and-tube heat exchanger.

[0013] Furthermore, a cleaning liquid supply pipe A is connected to the top of the inner cavity of the sterilization tank, and a cleaning ball is installed at the end of the cleaning liquid supply pipe A; a cleaning liquid supply pipe B is connected to the finished product discharge pipe.

[0014] Furthermore, a cleaning solution return pipe is connected to the sterilization return pipe.

[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0016] The beverage enters the tube side of the tubular heat exchanger from the raw liquid inlet pipe and circulates between the tube side and the inner cavity of the sterilization tank. During the circulation process, steam enters the shell side of the tubular heat exchanger and uses steam heating to sterilize and fix the circulating beverage, while retaining the original flavor substances and nutrients of the beverage. It has high sterilization temperature, low energy consumption and good color fixation effect.

[0017] After the beverage is sterilized, cooling water enters the shell side of the shell-and-tube heat exchanger. Under the action of the cooling water, the beverage is rapidly cooled, ensuring that it is fully sterilized and color-fixed while preventing browning due to excessive heating time.

[0022] like Figure 1 As shown, this utility model provides a beverage sterilization and color-fixing device, including a sterilization tank 1 and a tubular heat exchanger 2, with an air filter 16 installed on the top of the sterilization tank 1.

[0023] The bottom outlet of the sterilization tank 1 is connected to one end of the sterilization feed pipe 3, and the other end of the sterilization feed pipe 3 is connected to the tube inlet of the shell and tube heat exchanger 2. A circulation pump 15 is installed on the sterilization feed pipe 3.

[0024] The tube-side outlet of the shell-and-tube heat exchanger 2 is connected to one end of the sterilization reflux pipe 4, and the other end of the sterilization reflux pipe 4 is connected to the reflux port of the sterilization tank 1.

[0025] The circulating pump 15 provides power for the flow of the raw liquid, causing the raw liquid to circulate between the tube side of the tubular heat exchanger 2 and the inner cavity of the sterilization tank 1. The raw liquid is sterilized and fixed in color during the circulation process.

[0026] The sterilization feed pipe 3 is connected to the raw liquid feed pipe 9, and the connection point is located on the pipeline between the circulating pump 15 and the shell and tube heat exchanger 2.

[0027] The shell-side inlet of the tubular heat exchanger 2 is connected to the steam inlet pipe 5, and the shell-side outlet of the tubular heat exchanger 2 is connected to the steam drain pipe 6. Steam heating is used to sterilize and fix the beverage circulating within the tubes of the tubular heat exchanger 2.

[0028] The shell-side outlet of the tubular heat exchanger 2 is also connected to the cooling water inlet pipe 7, and the shell-side inlet of the tubular heat exchanger 2 is also connected to the cooling water outlet pipe 8. The cooling water heat exchange method rapidly cools the beverage circulating within the tubes of the tubular heat exchanger 2 after sterilization, ensuring that the beverage does not undergo browning due to excessive heating time.

[0029] The sterilization feed pipe 3 is also connected to the finished product discharge pipe 10, and the connection point is located on the pipeline between the circulating pump 15 and the shell and tube heat exchanger 2.

After cleaning, it is output through the cleaning fluid return pipe 14.

[0033] The specific working principle of this utility model is as follows:

[0034] The beverage enters the tubular heat exchanger 2 from the inlet pipe 9 and circulates between the tube side and the inner cavity of the sterilization tank 1. During this circulation, steam enters the shell side of the tubular heat exchanger 2, using steam heating to sterilize and fix the circulating beverage, while preserving its original flavor and nutrients. This method features high sterilization temperature, low energy consumption, and excellent color fixation. After sterilization, cooling water enters the shell side of the tubular heat exchanger 2, rapidly cooling the beverage to ensure thorough sterilization and color fixation while preventing browning due to prolonged heating.
