Description

Technical Field

[0001] This utility model relates to the technical field of yeast production and processing equipment, and in particular to a spiral mixing starch liquefaction steam injector for hydrolyzing sugar. Background Technology

[0002] Existing steam ejectors do not achieve good mixing when processing high-concentration, high-viscosity materials. They typically employ a method of pumping steam into the suction chamber, mixing it in the mixing chamber, and then ejecting the steam mixture in the diffusion chamber. This approach is ineffective for processing high-concentration, high-viscosity materials due to uneven mixing. Furthermore, to ensure proper ejection when dealing with high-concentration, high-viscosity materials, it is necessary to increase steam consumption, resulting in high energy consumption. Utility Model Content

[0003] This invention provides a spiral mixing starch liquefaction steam jet for hydrolyzing sugar, aiming to solve the problems of uneven mixing and high energy consumption of existing steam jets for high-concentration, high-viscosity materials.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A spiral mixing steam jet for hydrolyzing sugar starch includes an intake chamber, a mixing chamber, and a diffusion chamber connected in sequence. The intake chamber is coaxially provided with a partition, and the intake chamber is divided into two independent chambers by the partition. The chamber away from the mixing chamber is a steam chamber, and the chamber closer to the mixing chamber is a liquid chamber. The partition is provided with a nozzle, and the steam chamber and the liquid chamber are connected through the nozzle. The inner wall of the nozzle is coaxially provided with a spiral guide groove.

[0006] The nozzle's feed end is located inside the steam chamber, and the nozzle's discharge end is located inside the liquid chamber.

[0007] The nozzle is a conical nozzle, with the small-diameter side being the discharge end and the large-diameter side being the feed end. The spiral guide groove is concentric and coaxial with the nozzle.

[0008] The nozzle and the baffle are arranged concentrically and coaxially.

[0009] The steam chamber has an air inlet on its outer side along the radial direction, and the external steam supply mechanism is connected to the air inlet through a flange.

[0010] The liquid chamber has a radial inlet on its outer side, and the external liquid supply mechanism is connected to the inlet via a flange.

[0011] The inhalation chamber is movably mounted with a control structure on a coaxial axis. The control structure includes a control rod and a control head that are coaxially connected. The control head is concentric and coaxial with the nozzle, and the control head is movably embedded in the nozzle and forms a releasable sealing fit with the nozzle.

[0012] The beneficial effects of this utility model are:

[0013] Based on the needs of starch hydrolysate liquefaction steam injection technology, this utility model has made structural improvements to the existing steam injector. The nozzle structure has been changed to a threaded shape to guide the steam to rotate and improve the mixing effect between the steam and the material. Overall, the liquefaction efficiency of starch hydrolysate liquefaction steam injection is improved, while the steam consumption during starch hydrolysate liquefaction steam injection is reduced.

[0019] The embodiments will be further described below with reference to the accompanying drawings.

[0020] like Figures 1-2 As shown in the preferred embodiment 1, a spiral mixing starch liquefaction steam ejector for hydrolyzed sugar includes an intake chamber 1, a mixing chamber 2, and a diffusion chamber 3 connected in sequence. The intake chamber 1 is coaxially equipped with a partition 11, which divides the intake chamber 1 into two independent chambers. The chamber away from the mixing chamber 2 is a steam chamber 5, and the chamber closer to the mixing chamber 2 is a liquid chamber 6. The partition 11 is equipped with a nozzle 9, and the steam chamber 5 and the liquid chamber 6 are connected through the nozzle 9. The inner wall of the nozzle 9 is coaxially equipped with a spiral guide groove 10. The spiral guide groove 10 causes the steam to rotate when it enters the liquid chamber 6 from the steam chamber 5 through the nozzle 9, forming a spiral gas, which enhances the mixing effect and improves the liquefaction efficiency of the starch hydrolyzed sugar liquefaction steam ejection, while reducing the steam consumption during the starch hydrolyzed sugar liquefaction steam ejection.

[0021] Preferably, the nozzle 9 is detachably fixed to the partition plate 11 via a flange.

[0022] The feed end of the nozzle 9 is located inside the steam chamber 5, and the discharge end of the nozzle 9 is located inside the liquid chamber 6, ensuring that steam enters the liquid chamber 6 from the steam chamber 5 and is output in one direction.

[0023] The nozzle 9 is a conical nozzle with the small diameter side being the discharge end and the large diameter side being the feed end. The spiral guide groove 10 is concentric and coaxial with the nozzle 9 to ensure that a spiral steam flow is formed at the center position, so that the material is mixed evenly.

[0024] The nozzle 9 and the baffle 11 are arranged concentrically and coaxially to ensure that a spiral steam flow is formed at the center position, so that the material is mixed evenly.

[0025] The steam chamber 5 has an air inlet 8 on its outer side along the radial direction, and the external steam supply mechanism is connected to the air inlet 8 through a flange to ensure the supply of steam.

[0026] The liquid chamber 6 is provided with a liquid inlet 7 on the outer side in a radial direction, and the external liquid supply mechanism is connected to the liquid inlet 7 through a flange to ensure the supply of materials.

[0027] The inhalation chamber 1 is movably mounted with a control structure 4 on a coaxial basis. The control structure 4 includes a control rod 41 and a control head 42 connected on a coaxial basis. The control head 42 is concentric and coaxial with the nozzle 9, and the control head 42 is movably embedded in the nozzle 9 and forms a releasable sealing fit with the nozzle 9 to control the overall process.

[0028] As a preferred embodiment 2, the nozzle 9 is made of titanium alloy to improve its durability when spiraling steam.

[0029] The working principle of this utility model:

[0030] Based on the requirements of starch hydrolysate liquefaction steam injection technology, structural improvements were made to the existing steam injector. The nozzle 9 is equipped with a spiral guide groove 10 to guide the steam to rotate, improve the mixing effect of steam and material, and improve the overall liquefaction efficiency of starch hydrolysate liquefaction steam injection. At the same time, the steam consumption during starch hydrolysate liquefaction steam injection was reduced.
