Description

Technical Field

[0001] The invention belongs to the technical field of chocolate processing, and in particular relates to a continuous temperature regulating machine for chocolate processing. Background Art

[0002] Chocolate contains a lot of cocoa butter, which starts to soften at around 28°C, and the solid components quickly turn into liquid at around 33°C. In order to make chocolate more shiny, harder and mellower in taste, chocolate needs to be tempered during processing. Temperature has a great influence on the quality of chocolate. If the melting temperature is too high, the cocoa butter or other solids in the chocolate will be destroyed or decomposed due to the high temperature. In addition, the chocolate slurry has a high viscosity and low fluidity. During the tempering process, it is easy to deposit at the bottom of the mixing tank, affecting the quality of the chocolate slurry and making it difficult to clean the mixing tank.

[0022] The embodiment of the present invention provides a continuous tempering machine for chocolate processing, comprising a mounting frame 1. For example, Figure 1 , Figure 2 and Figure 3As shown, several groups of movable doors 3 are arranged around the installation frame 1. A heating tank 9 is arranged inside the installation frame 1; a motor 8 is installed on the top of the heating tank 9. Several groups of steam generators 6 are arranged at equal intervals in the vertical direction inside the installation frame 1; the output end of each group of steam generators 6 is connected to a group of steam regulating valves 7; the output end of each group of steam regulating valves 7 is connected to the inside of the heating tank 9. A water outlet 4 and a water inlet 5 are arranged at the bottom of the installation frame 1; the water inlet 5 is connected to the input end of the steam regulating valve 7. A condenser is arranged inside the installation frame 1; the output end of the condenser is connected to the water outlet 4; the input end of the condenser is connected to the inside of the heating tank 9.

[0023] For example, Figure 4 As shown, the heating tank 9 is provided with a heating chamber 12; the heating chamber 12 is provided with a temperature regulating tank 13; a fixed collar 14 is sleeved on the outer wall of the temperature regulating tank 13; the fixed collar 14 is fixedly connected to the inner wall of the heating chamber 12. A rotating rod 15 is rotatably connected in the temperature regulating tank 13 along the central axis direction; one end of the rotating rod 15 extends to the outside of the heating tank 9 and is transmission-connected to the output end of the motor 8. A plurality of groups of stirring rods 16 are provided on the outer wall of the rotating rod 15; a group of side scrapers 17 are fixedly connected to the end of each group of stirring rods 16 away from the rotating rod 15; a side wall of each group of side scrapers 17 away from the corresponding group of rotating rods 15 is movably in contact with the side wall of the temperature regulating tank 13; a bottom scraper 18 is fixedly connected to the end of the rotating rod 15 away from the motor 8; a side wall of the bottom scraper 18 away from the rotating rod 15 is movably in contact with the bottom inner wall of the temperature regulating tank 13. A temperature sensor 19 is provided on the outer wall of the rotating rod 15. A feed port 10 is provided at the bottom center of the temperature regulating tank 13; one end of the feed port 10 extends to the outside of the mounting frame 1. A drain port 11 is provided at the bottom of the heating chamber 12; one end of the drain port 11 extends to the outside of the mounting frame 1. An exhaust port 20 is provided at the top of the temperature regulating tank 13; the exhaust port 20 is connected to the outside of the mounting frame 1.

[0024] The working principle and method of using the continuous tempering machine for chocolate processing proposed by the present invention are as follows: chocolate is transported to the tempering tank 13 through the feed port, water is input into the steam generator 6 through the water inlet 5, the steam generator 6 evaporates the water into steam, and after adjusting the pressure and temperature through the steam regulating valve 7, it is transported to the heating chamber 12 to heat the tempering tank 13. After entering the heating chamber 12, the steam is condensed by the condenser and becomes water again, and then it is input into the steam generator 6 through the water outlet 4 to be reheated to form a heating circuit. The condensed water in the heating chamber 12 is discharged through the drain port 11. During the heating process, the motor 8 drives the rotating rod 15 to rotate, so that the stirring rod 16 provided on the outer wall of the rotating rod 15 stirs the chocolate, and at the same time, the side scraper 17 and the bottom scraper 18 continuously scrape the chocolate attached to the inner wall of the temperature regulating tank 13, and the temperature sensor 19 continuously monitors the temperature in the temperature regulating tank 13. When the temperature is too high or too low, it will send a signal to control the steam regulating valve 7 to adjust the steam temperature to keep the temperature in the temperature regulating tank 13 constant. The air expanded during the heating process is discharged through the exhaust port 20. When the heating is completed, the chocolate is discharged through the discharge port 10 for the next step of production.

[0025] During the heating process, the motor 8 drives the rotating rod 15 to rotate, so that the stirring rod 16 arranged on the outer wall of the rotating rod 15 stirs the chocolate. At the same time, the side scraper 17 and the bottom scraper 18 continuously scrape the chocolate attached to the inner wall of the temperature regulating tank 13, so that the chocolate is heated more evenly, thereby improving the quality of the chocolate after it is made.
