Description

Technical Field

[0001] This utility model belongs to the field of food processing, specifically relating to a defrosting device for quick-frozen foods. Background Technology

[0002] In the frozen food processing industry, defrosting is a crucial process. During storage and transportation, frost easily forms on the surface of frozen foods. If defrosting is not carried out effectively, it will not only affect the taste and quality of the food, but may also have an adverse impact on subsequent processing and packaging.

[0003] Ordinary defrosting devices for frozen foods typically use warm water spraying to thaw the food. The working principle of this method is to use the heat of the warm water to melt the frost, thereby achieving the purpose of defrosting. However, this defrosting method has certain drawbacks. After spraying warm water, some frost often remains. This is because the spray of warm water may not evenly cover all areas of the food surface, or the parameters such as water temperature and spraying time may not be set properly, resulting in some frost not melting completely. At the same time, spraying warm water will also leave moisture on the food surface. This residual moisture will not only affect the taste and shelf life of the food, but may also refreeze due to the low temperature of the food itself, forming new frost, further affecting the quality of the food. Utility Model Content

[0004] To overcome the problem that residual moisture may remain in the defrosting device for quick-frozen foods during use, leading to re-frost formation and even affecting food quality, a new type of defrosting device for quick-frozen foods is proposed.

[0005] The technical solution of this utility model is as follows: a defrosting device for quick-frozen food, including a conveying device and a cleaning mechanism. The conveying device includes a conveyor frame and a conveyor. A defrosting mechanism and a defrosting mechanism distributed on the left and right sides are installed at the upper end of the conveying device. A cleaning mechanism is installed at the right end of the conveying device. The cleaning mechanism includes a cleaning box, which is fixed to the right end of the conveyor frame. Three brush rollers distributed on the left and right sides are rotatably installed on the inner walls of the front and rear ends of the cleaning box. Gear 1 is fixedly connected to the front end shaft of the left brush roller, gear 2 is fixedly connected to the front end shaft of the middle brush roller, and gear 3 is fixedly connected to the front end shaft of the right brush roller. Idler wheel 1 and idler wheel 2 are rotatably installed on the outer wall of the cleaning box. Idler wheel 1 is located between gear 1 and gear 2 and meshes with gear 1 and gear 2 respectively. Idler wheel 2 is located between gear 2 and gear 3 and meshes with gear 2 and gear 3 respectively. A servo motor is installed on the outer wall of the cleaning box. The output end of the servo motor is connected to the shaft of the brush roller. Brush plates are installed on the inner walls of the front and rear ends of the cleaning box, and the brush plates correspond to the brush rollers.

[0006] Furthermore, conveyors are installed on the inner walls of the front and rear ends of the conveyor frame, and a feed box is fixed to the upper edge of the conveyor frame. The thawing mechanism includes a thawing box.

[0007] Furthermore, the thawing box is fixed to the upper end of the conveyor frame, the left end of the thawing box is attached to the right end of the feed box, and several multi-hole nozzles with equal spacing on the left and right sides are fixed to the upper inner wall of the thawing box.

[0008] Furthermore, a water pump is fixedly connected to the upper end of the defrosting box, a water tank is connected to the water inlet of the water pump, and the water outlet of the water pump is connected to a multi-hole nozzle pipe. The defrosting mechanism includes an air box.

[0009] Furthermore, the bellows is fixed to the upper end of the conveyor frame, the left end of the bellows is attached to the right end of the defrosting box, and the right end of the bellows is fixed to the heating box.

[0010] Furthermore, an air grid is fixedly connected to the upper inner wall of the air box, and a fan is fixedly connected to the upper end of the air box. The air outlet of the fan is connected to the air grid duct.

[0011] Furthermore, a heater is fixed to the upper inner wall of the heating box, and the output ends of the heater, air grid, and multi-hole nozzle are all corresponding to the upper end of the conveyor, and the output end of the conveyor is corresponding to the brush roller.

[0012] Furthermore, a collection box is fixed to the lower inner wall of the conveyor frame. The collection box is located on the lower side of the conveyor, and the upper opening of the collection box corresponds to the defrosting mechanism and the thawing mechanism.

[0013] The beneficial effects of this utility model are as follows: The output end of the servo motor can drive the brush roller to rotate. When the left brush roller rotates, it can drive gear one to rotate, thereby driving idler gear one to mesh with gear two to rotate, and then driving idler gear two to mesh with gear three to rotate, so that the three brush rollers rotate synchronously and in the same direction. This can carry the defrosted material through the lower end of the brush plate, and the brush rollers cooperate with the brush plate to clean the surface of the material. Compared with the existing defrosting device for quick-frozen food, the added cleaning mechanism can clean the defrosted material and remove the water stains and dirt remaining on the surface of the material, so as to prevent water stains from re-frost or affecting the quality of the material.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-6 This utility model provides an embodiment of a defrosting device for quick-frozen food, including a conveying device 1 and a cleaning mechanism 2. The conveying device 1 includes a conveyor frame 101 and a conveyor 102. A defrosting mechanism 3 and a defrosting mechanism 4, distributed horizontally, are installed on the upper end of the conveying device 1. The cleaning mechanism 2 is installed on the right end of the conveying device 1. The cleaning mechanism 2 includes a cleaning box 201, which is fixedly connected to the right end of the conveyor frame 101. Three brush rollers 202, equidistantly distributed horizontally, are rotatably installed on the inner walls of the front and rear ends of the cleaning box 201. A gear 1 203 is fixedly connected to the front end shaft of the left brush roller 202, a gear 204 is fixedly connected to the front end shaft of the middle brush roller 202, and a gear 204 is fixedly connected to the front end shaft of the right brush roller 202. Gear 3 205 is fixedly connected to the front rotating shaft. Idler wheel 1 206 and idler wheel 207 are rotatably installed on the outer wall of the cleaning box 201. Idler wheel 1 206 is located between gear 1 203 and gear 2 204 and meshes with gear 1 203 and gear 2 204 respectively. Idler wheel 207 is located between gear 2 204 and gear 3 205 and meshes with gear 2 204 and gear 3 205 respectively. Servo motor 208 is installed on the outer wall of the cleaning box 201. The output end of servo motor 208 is connected to the rotating shaft of brush roller 202. Brush plates 209 are installed on the inner walls of the front and rear ends of the cleaning box 201 and correspond to brush roller 202.

[0023] The material is conveyed sequentially through the conveyor 102 in the conveying device 1, passing through the thawing mechanism 3, the defrosting mechanism 4, and the cleaning mechanism 2. The thawing mechanism 3 thaws the material, the defrosting mechanism 4 defrosts the thawed material, and finally the cleaning mechanism 2 cleans the material. The output of the servo motor 208 drives the brush roller 202 to rotate. When the left brush roller 202 rotates, it drives the gear 1 203 to rotate, which in turn drives the idler wheel 1 206 to mesh with the gear 204 to rotate, and the idler wheel 207 to mesh with the gear 3 205 to rotate, so that the three brush rollers 202 rotate synchronously and in the same direction. This allows the defrosted material to pass through the lower end of the brush plate 209, and the brush rollers 202 work with the brush plate 209 to clean the surface of the material, preventing residual water stains from refreezing or contaminating the material.

[0024] Please see Figures 3-4 In this embodiment, a conveyor 102 is installed on the inner walls of the front and rear ends of the conveyor frame 101. A feed box 104 is fixedly connected to the upper edge of the conveyor frame 101. The defrosting mechanism 3 includes a defrosting box 301. In use, the material to be defrosted can be introduced into the upper end of the conveyor 102 through the feed box 104, so that the conveyor 102 can transport the material. The defrosting box 301 is fixedly connected to the upper end of the conveyor frame 101. The left end of the defrosting box 301 is attached to the right end of the feed box 104. Several multi-hole nozzles 302 with equal left and right distances are fixedly connected to the upper inner wall of the defrosting box 301. In use, the multi-hole nozzles 302 can evenly distribute the water flow and guide the water flow to be evenly sprayed on the surface of the material.

[0025] Please see Figures 4-6 In this embodiment, a water pump 303 is fixedly connected to the upper end of the defrosting box 301. The water inlet of the water pump 303 is connected to a water tank, and the water outlet of the water pump 303 is connected to a multi-hole nozzle 302. The defrosting mechanism 4 includes a blower box 401. In use, the water pump 303 can draw water out and guide it into the multi-hole nozzle 302 to spray water to defrost the materials on the conveyor 102. The blower box 401 is fixedly connected to the upper end of the conveyor frame 101. The left end of the blower box 401 is attached to the right end of the defrosting box 301, and the right end of the blower box 401 is fixedly connected to a heating box 402. In use, the materials can be defrosted through the blower box 401 and the heating box 402.

[0026] Please see Figures 2-6In this embodiment, an air grid 404 is fixedly connected to the upper inner wall of the air box 401, and a fan 403 is fixedly connected to the upper end of the air box 401. The air outlet of the fan 403 is connected to the air grid 404 via a pipe. During use, air can be blown by the fan 403, and the air grid 404 can evenly distribute the airflow on the material surface for dehydration and defrosting. A heater 405 is fixedly connected to the upper inner wall of the heating box 402. The output ends of the heater 405, the air grid 404, and the multi-hole nozzle 302 are all corresponding to the upper end of the conveyor 102. The output end corresponds to the brush roller 202. During use, the heater 405 can heat the heating box 402 and the air box 401 to improve the defrosting effect. The lower inner wall of the conveyor frame 101 is fixed with a collection box 103. The collection box 103 is located on the lower side of the conveyor 102. The upper opening of the collection box 103 corresponds to the defrosting mechanism 3 and the defrosting mechanism 4. During use, the collection box 103 can collect the water flow sprayed from the multi-hole nozzle 302 and the water flow de-misting from the heating box 402 to prevent water overflow from affecting the processing.

[0027] During operation, firstly, the conveyor 102, fan 403, heater 405, and servo motor 208 are started. The heater 405 heats the air box 401 and the heating box 402. The servo motor 208 drives the three brush rollers 202 to rotate. Next, the material to be defrosted is poured into the upper end of the conveyor 102 through the upper opening of the feed box 104. When the conveyor 102 transports the material to the defrosting box 301, the water pump 303 is started to pump water to the multi-hole nozzle 302, which sprays water onto the surface of the material to defrost it. Then, the material undergoes preliminary dehydration and defrosting through the air box 401 and the heating box 402. After the material enters the upper end of the brush rollers 202, the brush rollers 202 drive the material through the brush plate 209 for cleaning. After cleaning, the material is collected in a container. Finally, the wastewater in the collection box 103 is cleaned using a water pump.

[0028] Through the above steps, the output of the servo motor 208 can drive the brush roller 202 to rotate. When the left brush roller 202 rotates, it can drive the gear 1 203 to rotate, thereby driving the idler wheel 1 206 to mesh with the gear 204 to rotate, and driving the idler wheel 207 to mesh with the gear 3 205 to rotate, so that the three brush rollers 202 rotate synchronously and in the same direction. This can drive the defrosted material to pass through the lower end of the brush plate 209, and make the brush rollers 202 cooperate with the brush plate 209 to clean the surface of the material. This solves the problem that moisture may remain in the defrosting device for quick-frozen foods during use, which may cause re-frost or even affect the quality of the food.
