Description

Technical Field

[0001] This utility model relates to the field of evaporation and concentration technology, specifically to a maltose evaporation and concentration device. Background Technology

[0002] Maltose is a food product whose main component is sugar. It has a long history in China and is one of the more popular foods there. With the improvement of modern production levels and the monitoring of food safety, maltose can now be produced in a modern way. Thanks to the advancement of production technology, maltose can be produced in large quantities with high efficiency. Maltose production requires concentration because it is made from a mixture of various raw materials, so evaporation and concentration are necessary to give the produced maltose a good taste.

[0003] A Chinese patent with publication number CN112481424A discloses a maltose evaporation and concentration device. The device consists of an inner groove in the center of a container, an outer ring located away from the inner groove, and a vacuum insulation plate filled within the outer ring. An inner ring, filled with insulating cotton, is located between the outer ring and the inner groove. Multiple heating tubes are evenly connected within the inner groove. The arrangement of these heating tubes improves heating efficiency, ensures uniform heating, prevents high temperatures from radiating to the outside, and maintains a constant temperature.

[0004] In the existing technology, when maltose is evaporated by heating tubes, the maltose near the container gradually decreases after evaporation. During the decrease, because the inner wall of the container is in direct contact with the maltose, the maltose sticks to the inner wall of the container during the descent and caramelizes, which reduces the evaporation efficiency in the container. At the same time, because maltose is highly adhesive, most of it sticks to the inner wall of the container during discharge, making it difficult to clean. Utility Model Content

[0005] The purpose of this invention is to provide a maltose evaporation and concentration device. Using this device solves the problem that when maltose is evaporated through a heating tube, the maltose near the container gradually decreases after evaporation. During this process, because the inner wall of the container is in direct contact with the maltose, the maltose sticks to the inner wall of the container during the descent and caramelizes, reducing the evaporation efficiency within the container. Furthermore, due to the strong adhesiveness of maltose, most of it adheres to the inner wall of the container during discharge, making it difficult to clean.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a maltose evaporation and concentration device, comprising a concentration tank, a water supply pipe installed on the outside of the concentration tank, an exhaust pipe installed on the outside of the concentration tank, a connecting device installed at the upper end of the concentration tank, the concentration tank including an insulated outer shell, a base plate fixedly installed at the lower end of the insulated outer shell, a heating tube installed on the inner side of the insulated outer shell, an insulated inner shell installed on the inner side of the heating tube, and a stirring assembly installed inside the insulated inner shell. The stirring assembly includes a rotating motor, the outer shell of the rotating motor being fixedly connected to the lower end of the base plate, a rotating rod fixedly installed at the drive end of the rotating motor, the rotating rod penetrating the base plate and rotatably connected thereto, a spiral winch fixedly installed on the outer side of the rotating rod, the spiral winch being frustoconical in shape, at least two sets of connecting rods fixedly installed on the outer side of the rotating rod, a scraping rod fixedly installed at the end of the connecting rod away from the rotating rod, the scraping rod being in contact with the insulated inner shell. Rubber strips are fixedly installed on both sides of the scraper rod. Maltose is poured into the inner insulated shell for concentration. First, hot water is introduced into the water supply pipe to heat the heating tube. The heating tube conducts heat through the inner insulated shell to the maltose for evaporation and concentration. At the same time, the rotating motor drives the auger to stir the maltose, accelerating its evaporation rate. A large amount of steam generated during evaporation is discharged through the exhaust pipe. To prevent maltose from sticking to the inner wall of the container after evaporation and causing scorching, the rotating rod drives the auger to stir while simultaneously scraping the inner wall of the inner insulated shell. This effectively prevents adhesion to the inner wall of the device. At the same time, when the concentrated maltose is discharged, the scraper rod scrapes the inner wall of the inner insulated shell to remove any remaining maltose, effectively cleaning the inner wall of the inner insulated shell and reducing losses.

[0007] Preferably, two sets of observation holes are installed through the interior of the outer and inner insulation shells, and at least three sets of support legs are fixedly installed at the lower end of the outer insulation shell. When stirring maltose, the stirring condition of maltose can be observed through the observation holes to determine the stirring time.

[0008] Preferably, the water supply pipeline includes a fixed pipe, one end of which is fixedly connected to a connecting device. A tee pipe is fixedly installed on the outside of the fixed pipe and is connected to the fixed pipe. A connecting pipe is fixedly installed at the lower end of the tee pipe, and a control valve is fixedly installed at the lower end of the connecting pipe. A bend is fixedly installed at the lower end of the control valve. The bend penetrates the insulation shell and is connected to the heating pipe. When the control valve is opened, hot water is introduced into the fixed pipe, allowing the hot water to flow into the bend through the tee pipe and then heat and evaporate the maltose inside the insulation shell through the heating pipe.

[0009] Preferably, a drain valve is installed through the upper end of the heat-insulating shell. The drain valve is connected to the heating pipe. Hot water flowing into the heating pipe is discharged through the drain valve, so that heat is circulated and conducted in the heating pipe to concentrate the maltose.

[0010] Preferably, the exhaust pipe includes a second connecting pipe, a second control valve is fixedly installed at the lower end of the second connecting pipe, and a second bend is fixedly installed at the lower end of the second control valve. The second bend passes through the outer insulation shell and the inner insulation shell and is connected to the interior of the inner insulation shell. When the steam generated by the evaporation of maltose causes the gas pressure inside the tank to be too high, the steam inside the inner insulation shell is discharged through the second connecting pipe by opening the second control valve, thereby maintaining the normal operation of the tank.

[0011] Preferably, a discharge port is installed through the lower ends of the heat-insulating outer shell and the heat-insulating inner shell, and the discharge port is connected to the interior of the heat-insulating inner shell, through which the concentrated maltose is discharged.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention discloses a maltose evaporation and concentration device. Maltose is poured into an insulated inner shell for concentration. First, hot water is introduced into a water supply pipe to heat a heating element. The heating element conducts heat through the insulated inner shell to the maltose for evaporation and concentration. Simultaneously, a rotating motor drives a winch to stir the maltose, accelerating the evaporation rate. A large amount of steam generated during evaporation is discharged through an exhaust pipe. To prevent maltose from sticking to the inner wall of the container after evaporation and causing scorching, a rotating rod drives the winch to stir while simultaneously driving a scraper to scrape the inner wall of the insulated inner shell, effectively preventing adhesion. Furthermore, when discharging the concentrated maltose, the scraper scrapes away any remaining maltose from the inner wall, effectively cleaning the inner shell and reducing losses.

The scraper rod 185 is fixedly installed with rubber strips 1851 on both sides. Maltose is poured into the heat-insulating inner shell 17 for concentration. First, hot water is introduced into the water supply pipe 2 to heat the heating tube 16.
