Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving heat exchange equipment, and more specifically, to an energy-saving heat exchange equipment for heating candy slurry. Background Art

[0002] The slurry used in candy production is mainly starch syrup, such as glucose syrup, high fructose syrup (high fructose corn syrup), high maltose syrup, etc., which can extend the shelf life of the product, improve the toughness and transparency of the product, reduce the viscosity of the candy, improve the flavor, reduce production costs, etc. The candy can only be produced after heating.

[0003] For the heating of slurry in candy production, sandwich pots, heat-conducting oil sugar-boiling pots, normal pressure and vacuum sugar-boiling pots, and electromagnetic heating sugar-boiling pots are mostly used. These devices have the characteristics of high efficiency, uniform heating and precise temperature control.

[0004] However, when heating the syrup with the boiler, it was found that the heating area of ​​the boiler was fixed, the syrup in the boiler was heated unevenly, and the heating and cooling of the boiler were affected by the structure. The temperature control reaction time was long, which affected the overall production efficiency and temperature control. It was very easy for the syrup temperature to be too high or too low, resulting in greater energy consumption and difficulty in achieving effective energy saving and recycling, and the quality of the product was also affected. Moreover, heating directly through the boiler would cause the condensed water in the steam pipeline to flow into the sugar solution, causing the syrup to be contaminated, reducing the purity and quality.

[0005] In addition, there is also a method of using a tubular heat exchanger to heat the syrup to avoid the above problems. However, the viscosity and corrosiveness of the syrup make it impossible to achieve the expected effect by using the tubular heat exchanger, which will lead to increased production costs and impose greater restrictions on the tubular heat exchanger.

[0006] In order to solve the above problems, the present application proposes an energy-saving heat exchange device for heating candy slurry. Summary of the invention

[0007] The object of the present invention is to provide an energy-saving heat exchange device for heating candy slurry, which can quickly and accurately control the temperature to achieve the effect of energy-saving heat exchange, while avoiding the contamination of syrup by condensed water to ensure the production quality of candy.

[0008] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0009] An energy-saving heat exchange device for heating candy slurry, comprising an energy-saving heat exchanger,

[0010] An inner shell is located inside the outer shell to form a concentric structure, and a sandwich is formed between the outer shell and the inner shell to store heat in the outer ring area of ​​the energy-saving heat exchanger;

[0011] A heat absorption layer is provided on the outer side of the inner shell for absorbing the heat released outwards, and a heat conduction unit is provided in the interlayer and connected to the storage unit on the outer side of the heat absorption layer, so as to transfer the stored heat to the heat conduction plate inside the adapter unit, and preheat the syrup input into the liquid inlet pipe, so as to achieve the energy-saving effect of waste heat reuse;

[0012] Through the above technical solution, the syrup is preheated when entering the heat exchanger to prevent the temperature of the syrup from rising sharply and causing damage to the molecular structure. At the same time, this arrangement can also make more effective use of the waste heat in different areas of the heat exchanger, making the energy-saving and environmental protection performance stronger and more practical.

[0013] The liquid infusion pipes are evenly distributed on the layer plates in the vertical direction and are located inside the heat storage unit. The adjacent layer plates and the liquid infusion pipes are combined and immersed in the syrup fluid to form a heat exchange channel. The layer plates are used to make the syrup laminar flow, thereby reducing the flow resistance of the syrup particles.

[0014] Through the above technical solution, a laminated channel is formed to separate the syrup into multiple layers for transmission, which can prevent the syrup particles in different areas from affecting each other and increasing the resistance, and thereby prevent the syrup particles in different areas from turbulently flowing with each other, which can lead to the aggravation of particle adsorption.

[0015] A fixing unit, used for installing the housing and a heat storage unit thereunder, wherein the heat storage unit is used for storing waste heat of the energy-saving heat exchanger to achieve energy-saving effect;

[0016] The electric vibration units are arranged in groups of two on the upper and lower sides of the left and right ends of the housing, and the two electric vibration units in each group are adjacent and symmetrically distributed in the front-to-back direction, forming a staggered structure with the heat conduction unit;

[0017] The outer ring frame is located outside the infusion tube near both ends and is connected to an electric vibration unit, and the electric vibration unit is used to drive the infusion tube and the layer plate to vibrate up and down to make the syrup particles fall off;

[0018] Through the above technical solution, using the upper and lower symmetrical electric vibration unit, the syrup in the two end areas inside the heat exchanger can be prompted to quickly enter the liquid outlet of the heat exchanger to ensure the stable transmission of the subsequent syrup.

[0019] Beneficial effects of the present invention:

[0020] The present invention is a tubular energy-saving heat exchanger, which forms a heat exchange channel by immersing a layer plate in a syrup fluid, and utilizes a double-layer structure of an inner shell and an outer shell to install a heat absorption layer, a storage unit and a heat conduction unit inside the interlayer, thereby storing heat on the surface of the outer shell and transferring it to the heat conduction plate when in use, and preheating the syrup liquid entering the device. This arrangement can prevent the syrup temperature difference from changing too quickly, causing adverse reactions or decomposition of syrup components, and can also achieve the energy-saving effect of waste heat utilization.

[0021] The present invention combines the layer plate and the liquid guide tube, and during the syrup transportation and heating period, the parallel distribution of the liquid guide tube can be used to form a laminar flow state in the device, and the fluid particles move smoothly along the plane. Compared with the turbulent flow mode of the traditional tubular heat exchanger, the syrup flow rate is uniform, and the friction inside the fluid can be reduced to achieve the effect of reducing the syrup transmission resistance.

[0022] In addition, the infusion tube and its components are connected to the hot water inlet to form a combined structure, and then the infusion tube and the layer plate are vibrated up and down under the action of the electric vibration unit, prompting the particles in the syrup to break away and flow, thereby preventing the syrup particles from adsorbing the components in the equipment, thereby preventing the syrup from corroding the components.

[0023] Based on this, the tubular heat exchanger can replace the traditional boiler to perform energy-saving heat exchange heating treatment on the syrup, and effectively alleviate the impact of the viscosity and corrosiveness of the syrup on the equipment, thereby increasing the service life of the tubular energy-saving heat exchanger and reducing the equipment failure rate during use.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1 - Figure 7 As shown, the present invention provides an energy-saving heat exchange device for heating candy slurry.

[0041] like Figure 1 - Figure 7 As shown, an energy-saving heat exchange device for heating candy slurry includes an energy-saving heat exchanger 1;

[0042] The inner shell 101 is located inside the outer shell 100 to form a concentric structure. An interlayer is formed between the outer shell 100 and the inner shell 101 to store heat in the outer ring area of ​​the energy-saving heat exchanger 1. A heat absorption layer 102 is provided on the outer side of the inner shell 101 to absorb the heat released outward. A heat conduction unit 104 is provided in the interlayer to connect to the storage unit 103 outside the heat absorption layer 102, and is used to transfer the stored heat to the heat conduction plate 303 inside the junction area between the adapter unit 300 and the liquid inlet pipe 301, so as to preheat the syrup input into the liquid inlet pipe 301, thereby achieving the energy-saving effect of waste heat reuse.

[0043] The liquid infusion pipe 500 is evenly distributed vertically on the layer plate 501 and is located inside the heat storage unit 200. The adjacent layer plates 501 and the liquid infusion pipe 500 are combined and immersed in the syrup fluid to form a heat exchange channel. The layer plates 501 are used to make the syrup laminar flow, thereby reducing the flow resistance of the syrup particles;

[0044] The heat exchange pipe of the energy-saving heat exchanger 1 has a conical structure at both ends. The small diameter port is connected to the syrup inlet and outlet holes, while the large diameter port is adjacent to both ends of the infusion pipe 500, which is used to promote the circulation of syrup in the pipe to prevent residual.

[0045] The fixing unit 400 is used to install the housing 100 and the heat storage unit 200 thereunder, and the heat storage unit 200 is used to store the waste heat of the energy-saving heat exchanger 1 to achieve energy-saving effect;

[0046] The electric vibration units 403 are located in groups of two on the upper and lower sides of the left and right ends of the housing 100, and the two electric vibration units 403 in each group are adjacent and symmetrically distributed in the front-to-back direction, forming a staggered structure with the heat conduction unit 104;

[0047] The outer ring frame 404 is located outside the infusion tube 500 near both ends and is connected to the electric vibration unit 403. The electric vibration unit 403 is used to drive the infusion tube 500 and the layer plate 501 to vibrate up and down to make the syrup particles fall off.

[0048] The present embodiment provides a method for heating viscous and easily corrosive syrup using a stable tubular energy-saving heat exchanger. First, the heat collected by the heat absorption layer 102 and the storage unit 103 is used in advance by connecting the heat conduction unit 104 with the heat conduction disk 303 to preheat the incoming syrup to prevent its temperature from changing too much and causing crystallization that affects the taste and texture. In addition, during the heating of the syrup, the syrup is layered and transmitted using the infusion tube 500 and the layer plate 501 to form a laminar flow, so that syrup particles in different regions cannot affect each other and cause large-scale adsorption of components. During this period, the electric vibration unit 403 is used to drive the infusion tube 500 and the layer plate 501 to vibrate up and down through the outer ring frame 404, so that some of the adsorbed syrup particles can be quickly detached, which can not only ensure the uniformity of heating of the syrup particles, but also prevent the syrup particles from being adsorbed for a long time to form dirt that corrodes components.

[0049] like Figure 3 and Figure 4 As shown, the storage unit 103 is evenly distributed in sections outside the heat absorption layer 102, which is used to concentrate the heat stored in the heat absorption layer 102, which is convenient for the heat conduction of the heat conduction unit 104. The part of the heat conduction unit 104 exposed to the adapter unit 300 turns toward the axis direction of the adapter unit 300 until it is connected to the heat conduction plate 303. During the heat conduction, the sleeve 302 outside the adapter unit 300 is used to protect the heat conduction unit 104 to prevent the loss of heat during the period from affecting the waste heat reuse effect. The heat conduction plate 303 is a porous structure, which is used to ensure the stability of its transmission flow while preheating the syrup.

[0050] like Figure 5 As shown, an annular hollow tube 503 is provided at both ends of the infusion tube 500, a transfer tube 504 is provided on the side of the annular hollow tube 503 away from the infusion tube 500, which is connected to the heat transfer medium inlet and outlet of the heat exchanger, and a liquid guide tube 502 is provided on the inner side of the annular hollow tube 503, which is connected to the infusion tube 500 and the layer plate 501. The hollow groove inside the annular hollow tube 503 is used to guide the heat transfer medium input by the transfer tube 504 into the infusion tube 500 through the liquid guide tube 502 in a short time, and the same effect is achieved at the output end of the infusion tube 500, which is used to ensure smooth discharge of the heat transfer medium.

[0051] like Figure 1 and Figure 2 as well as Figure 5 - Figure 7As shown, an annular frame 401 is provided on the inner side of the fixed unit 400, which is installed on the outer sides of the two adjacent ends of the outer shell 100. The connection method between the heat storage unit 200 and the fixed unit 400 is the same as the connection method between the outer shell 100 and the fixed unit 400. Symmetrical brackets 402 are provided on the upper and lower sides of the annular frame 401 for installing electric vibration units 403 in groups of two. Holes for installing the bottom rods of the electric vibration units 403 are provided between the outer shell 100 and the inner shell 100, and a connector is provided on the inner side of the hole of the inner shell 101 to connect to the rods at the bottom of the electric vibration units 403, so as to seal the hole to prevent syrup from entering.

[0052] In addition, the outer wall of the outer ring frame 404 is flush with the annular hollow tube 503, and both have a certain gap with the inner wall of the inner shell 101 to provide micro-vibration space, and the transfer tube 504 is a hose structure to ensure stable transmission of the heat transfer medium during micro-vibration of the annular hollow tube 503.

[0053] It can be understood that the present invention immerses the infusion tube 500 and the layer plate 501 in the syrup fluid to form a plate-shaped heat exchange channel, which can effectively prevent syrup particles from adsorbing components during transmission and heating, and prevent them from being adsorbed for a long time to form dirt and corrode components. While increasing the service life of the equipment, it can also promote the circulation of syrup to improve the operating efficiency of the equipment.
