Description

Technical Field

[0001] The utility model relates to the technical field of concentrators, in particular to a clear juice concentrator with a preheating function. Background Art

[0002] The negative pressure concentrator utilizes the material to circulate and heat inside the equipment, and extracts the volatilized water vapor by forming a negative pressure inside the equipment. The working principle of the evaporator is that the material is pumped from the material tank into the first-effect evaporator through the material pump, and then the first-effect is pumped into the second-effect, the second-effect is pumped into the third-effect, the third-effect is pumped into the fourth-effect, and the fourth-effect is pumped into the material tank. The first-effect heating section is used as the main heating section and is heated by steam. The heating source of the second-effect heating section is the secondary steam separated from the first-effect separation layer. The third-effect heating section is the second-effect separation layer, and the fourth-effect heating section has a third-effect separation layer. The negative pressure of the heating section and the separation layer decreases step by step from the fourth effect to the first effect, which is conducive to the volatilization of the steam in the separation layer.

[0003] When the current multi-effect evaporator heats the material, the material needs to be gradually heated by multiple evaporators to complete the concentration. This will result in poor material heating effect and take a long time to complete the concentration of the material, making it difficult to meet production needs. Utility Model Content

[0021] See also Figure 1-4 , a clear juice concentrator with a preheating function, comprising a concentrating mechanism 1, wherein a preheating mechanism 2 is arranged inside the concentrating mechanism 1;

[0022] The concentration mechanism 1 can heat and concentrate the material, and the preheating mechanism 2 enables the material to be preheated before being added to the multiple evaporators, thereby improving the concentration efficiency of the material.

[0023] The concentration mechanism 1 includes a first-effect evaporator 101, a second-effect evaporator 102, a third-effect evaporator 103, a fourth-effect evaporator 104 and a material tank 105. The surfaces of the multiple evaporators are all connected with a delivery pipe 106, the surface of the delivery pipe 106 is connected with a first delivery pump 107, the surfaces of the multiple first delivery pumps 107 are connected with an output pipe 108, the surface of the first delivery pump 107 on the right side of the fourth-effect evaporator 104 is connected with a recovery pipe 109, and the recovery pipe 109 is connected with the material tank 105;

[0024] The first-effect evaporator 101 is connected to the external steam, and the material enters the first-effect evaporator 101 through the preheating mechanism 2. The steam heats the preheated material, and the heated material is then sequentially input into the second-effect evaporator 102, the third-effect evaporator 103 and the fourth-effect evaporator 104 through the delivery pipe 106, the first delivery pump 107 and the output pipe 108, thereby realizing multi-stage heating. Finally, the material will flow back into the material tank 105 through the first delivery pump 107 on the right side of the fourth-effect evaporator 104 and the recovery pipe 109, thereby completing the material concentration.

[0025] The preheating mechanism 2 includes a second delivery pump 201, which is connected to the material tank 105, and one end of the second delivery pump 201 is connected to the material pipe 202. The first effect evaporator 101, the second effect evaporator 102, the third effect evaporator 103 and the fourth effect evaporator 104 are all provided with a first preheating pipe 203. The material pipe 202 runs through the fourth effect evaporator 104 and is connected to the first preheating pipe 203 inside it. The surface of the first preheating pipe 203 is connected to a reducer 204, and the surface of the reducer 204 is connected to a second preheating pipe 205. The surface of the second preheating pipe 205 is connected to a connecting pipe 206, and one end of the connecting pipe 206 is connected to the first preheating pipe 203 on the left side. The surface of the second preheating pipe 205 in the first effect evaporator 101 is connected to a discharge pipe 207, and one end of the discharge pipe 207 is connected to the top of the inner wall of the first effect evaporator 101;

[0026] The second delivery pump 201 can extract the material in the material tank 105 and deliver it to the inside of the four-effect evaporator 104 through the material pipe 202. At this time, the first preheating pipe 203 in the four-effect evaporator 104 will be affected by the steam and heated up, so that the material entering it can be preheated and flow into the second preheating pipe 205 through the reducer 204. After being preheated in the first preheating pipe 203 and the second preheating pipe 205, the material can enter the first preheating pipe 203 in the three-effect evaporator 103, the second-effect evaporator 102 and the first-effect evaporator 101 in sequence through the connecting pipe 206. Finally, the material will be able to be input into the first-effect evaporator 101 through the discharge pipe 207, thereby completing the preheating of the material, which can better benefit the secondary steam inside the equipment, accelerate the condensation time of the secondary steam, speed up the concentration speed of the material, and improve the color and taste of the product.

[0027] Furthermore, the first preheating tube 203 and the second preheating tube 205 are both arranged in a spiral structure;

[0029] Furthermore, the diameter of the second preheating tube 205 is larger than that of the first preheating tube 203;

[0030] When the material passes through the first preheating tube 203 and the reducing tube 204 and enters the second preheating tube 205, the flow rate of the material will decrease due to the increase in the cross section, thereby increasing the residence time of the material.

[0031] Furthermore, a support plate 208 is fixed on the surface of the first preheating tube 203 and the second preheating tube 205;

[0032] The support plate 208 can support the first preheating tube 203 and the second preheating tube 205, thereby ensuring their stability during transportation.

[0033] Furthermore, the first preheating tube 203 and the second preheating tube 205 are both made of copper alloy, and their inner walls are chrome-plated;

[0034] Copper alloy has excellent thermal conductivity and can make good use of steam heat energy to preheat materials. At the same time, chrome plating can improve the corrosion resistance of the inner walls of the first preheating tube 203 and the second preheating tube 205, thereby extending their service life.

[0035] Furthermore, the support plate 208 is made of stainless steel;

[0036] The support plate 208 made of stainless steel has good high temperature resistance and material strength, and can provide stable support for the first preheating tube 203 and the second preheating tube 205 .

[0037] Furthermore, a controller 110 is fixed on the surface of the material tank 105 , and the controller 110 is electrically connected to the second delivery pump 201 and the first delivery pump 107 ;

[0038] The controller 110 is enabled to operate the second delivery pump 201 and the first delivery pump 107 .
