Description

Technical Field

[0001] This utility model relates to the field of quick-frozen fruit and vegetable blanching technology, and in particular to a quick-frozen fruit and vegetable pretreatment blanching device. Background Technology

[0002] Blanching, a pretreatment process for quick-frozen fruits and vegetables, involves immersing the prepared raw materials in boiling water or steam for an appropriate time. This process partially or completely deactivates various enzymes in the raw materials, preserving their original color while expelling gases from the cells, thus making it easier to preserve nutrients. Blanching also softens the fibrous tissue of vegetables and removes unpleasant pungent flavors.

[0003] The quick-frozen fruit and vegetable pretreatment blanching device described in announcement number CN215123914U includes a blanching box; a conveyor belt disposed on the blanching box; a support rod fixedly connected to the outer surface of the blanching box; a fixing structure disposed on the support rod; a fixing box with the fixing structure disposed on the outer surface of the fixing box; an extrusion structure disposed in the fixing box; a baffle shaft connected to the upper end of the fixing box; and a handle shaft connected to the outer surface of the baffle.

[0004] Based on the above technical features, the problem is that in the existing technology, after vegetables enter the blanching box, blanching will damage the cell wall structure of the fruits and vegetables, making them softer. Therefore, when the soft fruits and vegetables come into contact with each other, they are prone to being squeezed and sticking together, resulting in clumping. Consequently, the fruits and vegetables inside the clumps cannot fully contact the hot water, resulting in poor blanching effect, low blanching efficiency, and poor quality of the finished product.

[0005] Therefore, it is necessary to solve the above problems by using a quick-freezing fruit and vegetable pretreatment blanching device. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figures 1 to 4 The illustrated quick-freezing fruit and vegetable pretreatment blanching device includes a water tank 1. The cross-section of the tank body inside the water tank 1, which carries hot water, is an inverted isosceles trapezoid. The water tank 1 is equipped with existing heating elements for heating the water, which are prior art and will not be described in detail here.

[0024] Two support frames 2 are fixedly installed on the top of the water tank 1, and the two support frames 2 are respectively located on the front and rear sides of the top of the water tank 1. A mounting plate 3 is fixedly installed on the adjacent sides of the two support frames 2, and a chain conveyor mechanism is installed on the adjacent end face of the two mounting plates 3.

[0025] Both mounting plates 3 are inverted isosceles trapezoidal plates, and the bottom ends of both mounting plates 3 are located inside the water tank 1.

[0026] Specifically, the chain conveyor mechanism includes a chain 6. A motor 4 is fixedly mounted on a mounting plate 3, and the output shaft of the motor 4 is arranged horizontally in the front-to-back direction. A drive sprocket 5 is fixedly sleeved on the output shaft of the motor 4. Three driven sprockets are rotatably mounted on the mounting plate 3. The drive sprocket 5 and the three driven sprockets are arranged in a distribution pattern of the four corners of an isosceles trapezoid, and the two driven sprockets corresponding to the short base of the isosceles trapezoid are located inside the water tank 1. The drive sprocket 5 and the three driven sprockets are driven and sleeved within the chain 6.

[0027] The output shafts of the two chain conveyor motors 4 are coaxially opposite each other and electrically synchronized, that is, the output shafts of the two motors 4 rotate synchronously.

[0028] Multiple fixing seats 7 are fixedly installed on both chains 6, and the multiple fixing seats 7 on each chain 6 are evenly distributed at equal intervals along the direction of the chain 6.

[0029] Multiple fixed seats 7 on one chain 6 correspond one-to-one with multiple fixed seats 7 on another chain 6. A rotating shaft 8 is placed horizontally between each pair of corresponding fixed seats 7 in the front-to-back horizontal direction. Each rotating shaft 8 passes through the corresponding two fixed seats 7 and is rotatably connected to the corresponding two fixed seats 7.

[0030] Each rotating shaft 8 is fixedly equipped with a swing plate 9, which is used to break up fruit and vegetable clumps.

[0031] A horizontal pressure plate 11 is set between the two mounting plates 3, and the pressure plate 11 is fixedly connected to the two mounting plates 3. A transmission assembly is installed at the bottom of the pressure plate 11, which is used to drive the rotating shaft 8 to reciprocate in both forward and reverse directions.

[0032] Specifically, the transmission assembly includes multiple push blocks 12, all of which are fixed to the bottom of the pressure plate 11. The multiple push blocks 12 are evenly distributed at equal intervals along the left and right horizontal direction.

[0033] Each rotating shaft 8 is fixedly equipped with a swing block 10, and each push block 12 has a transmission inclined surface at the bottom that abuts against the swing block 10 for transmission cooperation.

[0034] Each rotating shaft 8 is fitted with a torsion spring. One end of each torsion spring is fixedly connected to the fixed seat 7 connected to the rotating shaft 8, and the other end of each torsion spring is fixedly connected to the swing plate 9 on the rotating shaft 8.

[0035] Working principle: In the blanching preparation stage, an appropriate amount of water is first injected into the water tank 1, and the existing heating element inside the water tank 1 is activated to heat the water to a temperature that meets the requirements for blanching quick-frozen fruits and vegetables, usually a suitable temperature to destroy the activity of fruit and vegetable enzymes, thus completing the hot water preparation before blanching. At the same time, the support frame 2 provides stable support for the entire device, and the mounting plates 3 fixed on the support frame 2 provide mounting bases for the two chain conveyor mechanisms, ensuring that the two chain conveyor mechanisms are symmetrically and stably arranged.

[0036] During the start-up phase of the conveying mechanism, the motors 4 of the two chain conveying mechanisms are activated. Since the two motors 4 are electrically synchronized, their output shafts drive the drive sprocket 5 to rotate synchronously. Because the drive sprocket 5 and three driven sprockets are connected to the chain 6 in a angular arrangement of an isosceles trapezoid, and the two driven sprockets with the shorter base of the isosceles trapezoid are located within the water tank 1, the rotation of the drive sprocket 5 causes the chain 6 to circulate along the trajectory of the drive sprocket 5 and the three driven sprockets. Multiple fixed seats 7 fixed on the chain 6 move synchronously with the chain 6, which in turn drives the rotating shaft 8 and the swing plate 9 fixed on the rotating shaft 8 to move, causing the swing plate 9 to gradually enter the hot water in the water tank 1. It should be noted that to ensure no fruits or vegetables are trapped between the driven sprockets and the chain 6, the hot water level is lower than the lower chain body of the chain 6.

[0037] During the blanching stage of fruit and vegetable placement and transportation, the prepared fruits and vegetables to be blanched are placed into water tank 1. The fruits and vegetables are then carried into the hot water in water tank 1 to begin the blanching process. During this process, the hot water acts on the fruits and vegetables, initially destroying the enzyme activity in the fruits and vegetables, and at the same time, it begins to expel the gas inside the fruit and vegetable cells, laying the foundation for maintaining the color of the fruits and vegetables and preserving nutrients in the later stages.

[0038] During the agglomeration and thorough blanching stage, when the rotating shaft 8 moves with the fixed base 7 to below the pressure plate 11, the swing block 10 fixed on the rotating shaft 8 will contact the transmission ramp of the push block 12 at the bottom of the pressure plate 11. As the chain 6 continues to move, the push block 12 pushes the swing block 10 to rotate around the rotating shaft 8 through the transmission ramp. The swing block 10 drives the rotating shaft 8 to rotate synchronously, and the rotating shaft 8 in turn drives the swing plate 9 to swing to one side. During this process, the torsion spring sleeved on the rotating shaft 8 is twisted and stores energy. When the swing block 10 moves with the rotating shaft 8 to the point of disengaging from the transmission ramp of the push block 12, the torsion spring releases the stored energy, driving the rotating shaft 8 to rotate in the opposite direction. The rotating shaft 8 in turn drives the swing plate 9 to swing back to the other side, realizing the reciprocating forward and reverse swing of the swing plate 9. While moving the fruits and vegetables, the swing plate 9 continuously breaks up the clumps formed by the softening of the cell walls of the fruits and vegetables through reciprocating swing, ensuring that each fruit and vegetable can fully contact the hot water in the water tank 1, avoiding the problem of insufficient blanching of fruits and vegetables inside the clumps, effectively improving the blanching effect and efficiency, while softening the fibrous tissue of fruits and vegetables and removing unpleasant pungent taste.

[0039] During the blanching and output stage, as the chain 6 continues to circulate and transport, the blanched fruits and vegetables are moved out of the hot water in the water tank 1 by the rotating shaft 8 and the swing plate 9, completing the pre-treatment blanching process of quick-frozen fruits and vegetables, and providing qualified fruit and vegetable raw materials for subsequent quick-freezing processing.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
