Description

Technical Field

[0001] The utility model relates to the technical field of bio-sugar processing, in particular to a bio-sugar heat exchange system. Background Art

[0002] The bio-sugar processing process usually involves steps such as sugar separation, purification and crystallization. The extractor extracts syrup from the raw materials, the centrifuge removes impurities and separates solids and liquids, the vacuum concentrator and heat exchange system are used to concentrate the syrup, and the heat exchange tubes in the evaporator are used to transport high-temperature steam medium to heat the syrup to promote the evaporation of water, so that the water in the syrup gradually evaporates and the syrup is concentrated.

[0003] A Chinese patent discloses a method for producing sugar from biomass (authorization publication number CN102311983B). The patented technology involves reacting a slurry of biomass feedstock, an inorganic metal salt, and a surfactant at 120°C to 180°C for 5 to 30 minutes. After the reaction, the solid-liquid mixture is directly used as the feedstock for enzymatic hydrolysis without separation. This hydrolysis yields a sugar-containing hydrolyzate. This method features a short operational flow, low energy consumption, high biomass utilization, and excellent saccharification results.

[0004] This patented technology achieves efficient biomass saccharification during use, but there are still some shortcomings during use. In the process of bio-sugar concentration and heat exchange, a heat exchanger is mostly used. The heat exchange tubes inside the heat exchanger are arranged on the internal side of the equipment. It takes a certain amount of time to conduct heat from the outside to the inside to heat the sugar liquid. The heat distribution is uneven, resulting in low heat exchange efficiency, extending the production cycle, and the steam is not fully exchanged. Part of the heat cannot be fully utilized, resulting in energy waste. Therefore, those skilled in the art provide a bio-sugar heat exchange system to solve the problems raised in the above background technology. Utility Model Content

[0047] The heat exchange structure 300 includes a heat exchange tube 301 suspended inside the lower cylinder 102, an inner spiral tube 302 and an outer spiral tube 303 that are interconnected and located at the center and inside the side of the lower cylinder 102 and communicate with the heat exchange tube 301, and an inlet 307 and an outlet 308 located at both ends of the heat exchange tube 301 and extending through the upper cylinder 101.

[0048] Hydraulic rods 103 are installed on both sides of the upper end of the base 105, and connecting blocks 104 are installed on both sides of the lower end of the hydraulic rods 103. The telescopic end of the lower end of the hydraulic rods 103 is connected to the connecting blocks 104. A feed port 108 is installed inside one end of the upper cylinder 101.

The interior of the upper cylinder 101 and the lower cylinder 102 are easy to clean.

At the same time, the stirring shaft 1 203 is engaged with the positioning hole 213 through the positioning block 212, driving the docking shaft 211 to rotate.
