Description

Technical Field

[0001] The utility model relates to the technical field of fermentation tanks, in particular to a molasses heat exchange device. Background Art

[0002] Fermentation tank refers to an industrial device used for microbial fermentation, and its main body is generally a main cylinder made of stainless steel plate. Molasses is a viscous, dark brown, semi-fluid object, which mainly contains a large amount of fermentable sugar (mainly sucrose), so it is a good fermentation raw material and can be used as a substrate or base material for fermented products such as yeast, monosodium glutamate, and organic acids. In the actual production process, when encountering high temperatures, the temperature of the fermentation tank often exceeds the normal temperature range of 29℃-31℃. Excessive temperature causes abnormal fermentation, reduced product output, and increased molasses consumption. When the existing technology controls the temperature of the fermentation tank to be too high, it is generally through spraying or other cooling components to act on the fermentation tank so that the temperature of the fermentation tank is not too high. In fact, the temperature of molasses added to the fermentation tank can generally reach 80℃, which is a major source of heat in the fermentation tank. The existing technology lacks temperature control measures for molasses. Utility Model Content

The bottom of the tank body 12 is connected to the plate heat exchanger 2 through a feed pipe 4, and a feed pump 41 is provided on the feed pipe 4. High-pressure gas enters the pressure tank 1 through the air inlet pipe 112, thereby increasing the pressure of the molasses. In conjunction with the feed pump 41, the flow rate of the molasses through the plate heat exchanger 2 is increased. The heat exchange efficiency of the molasses is improved. The plate heat exchanger 2 is provided with a discharge pipe 42, and the two ends of the discharge pipe 42 are respectively connected to the fermentation tank and the plate heat exchanger 2. The molasses enters the plate heat exchanger 2 through the feed pipe 4, and then exits the plate heat exchanger 2 through the discharge pipe 42 and enters the fermentation tank.

[0025] A boss 116 is provided on one side of the top cover 11 close to the tank body 12, and a sealing ring 115 is provided on the side of the boss 116, and the outer side of the sealing ring 115 contacts the inner side of the tank body 12. The boss 116 makes the top cover 11 and the tank body 12 more stable, and the sealing cavity increases the sealing performance of the top cover 11 and the tank body 12. A locking mechanism 13 is provided on the outer side of the tank body 12, and the locking mechanism 13 includes a second hinge 131, a threaded column 132 and a nut 133. The bottom end of the threaded column 132 is connected to the tank body 12 through the second hinge 131. The top cover 11 is provided with a slot 114 for matching the threaded column 132. The nut 133 is threadedly connected to the threaded column 132, and the bottom surface of the nut 133 contacts the top surface of the top cover 11.

[0026] A filter mechanism 43 is provided on the feed pipeline 4 on the side of the feed pump 41 close to the pressure tank 1. The filter mechanism 43 includes an outer groove 431 and a filter plate 432. The outer groove 431 is integrated with the feed pipeline 4.

One end of the return pipe 52 is connected to the plate heat exchanger 2, and the other end passes through the water tank 3 to communicate with the coil 53. The cooling water flows into the plate heat exchanger 2 from the water inlet pipe 51, and then flows into the coil 53 through the return pipe 52, and heat exchanges with the water in the water tank 3 in the coil 53. The cooled cooling water then enters the plate heat exchanger 2 through the water inlet pipe 51 to participate in circulating cooling. The circulation rate of the cooling water can be increased by cooperating with the water pump 511 provided on the circulating water cooling pipe 5.

[0028] The outer wall of the water tank 3 is provided with a water inlet 31 and a drain outlet, and the water tank 3 is provided with a thermometer 33.

[0029] The working principle of the specific implementation of the utility model is as follows: molasses is stored in the pressure tank 1, and the top cover 11 and the tank body 12 are tightly matched by the locking mechanism 13. High-pressure gas enters the pressure tank 1 through the air inlet pipe 112, the pressure of the molasses increases, and under the action of the feed pump 41, it passes through the plate heat exchanger 2, and finally enters the fermentation tank through the discharge pipe 42. The cooling water passes through the water inlet pipe 51, enters the plate heat exchanger 2 to participate in the heat exchange with the molasses, and then flows out of the plate heat exchanger 2 through the return pipe 52. The cooling water exchanges heat with the water in the water tank 3 in the coil 53. The cooling water with the lowered temperature enters the plate heat exchanger 2 through the water inlet pipe 51 to participate in the circulation cooling.
