Description

Technical Field

[0001] The present invention relates to the technical field of quick freezers, in particular to a quick freezer for food processing. Background Art

[0002] Fluidized quick freezer is a device that realizes fluidized single-body freezing of fruits, vegetables and some seafood. The frozen products move on the mesh belt. As the air flow speed increases, the food layer begins to loosen. When the wind pressure reaches a certain value, the food particles no longer remain static, and some particles float upward, causing the bed layer to expand and the porosity to increase, thus forming a fluidized bed. At this time, strong cold wind blows from the bottom up on the suspended food in the fluidized bed, and the frozen products are surrounded by cold wind in all directions to achieve rapid freezing of the food and form single bodies. The frozen food quickly passes through three stages of cooling, surface freezing and deep freezing, thereby obtaining high-quality quick-frozen food. This product is widely used for the rapid freezing of vegetables, fruits, fungi and granular, flaky and block foods.

[0003] The quick-freezing speed is the decisive factor in ensuring product quality. The faster the freezing speed, the better the product quality. Conversely, the longer the freezing time, the worse the quality. The existing fluidized bed quick-freezing machine spreads granular food on a conveyor belt. As the air flow speed increases, the food layer begins to loosen, causing some particles to float upward for rapid freezing. However, there is still a problem that some granular food in the lower layer is pressed down on the conveyor belt and cannot float. The contact area between the granular food and the cold air is smaller than that of the suspended particles, resulting in inconsistent quick-freezing speed and effect, and uneven product freezing quality. In view of this, we propose a quick-freezing machine for food processing. Summary of the Invention

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1 - Figure 7 As shown, this embodiment provides a quick-freezing machine for food processing, including a casing 1, an organic tank 10 is provided in the casing 1, a plurality of booster fans 11 are installed on the bottom wall of the tank 10, a pair of all-aluminum evaporators 12 are installed on the left wall of the tank 10, a baffle plate 13 with holes is provided on the right side of the all-aluminum evaporator 12, a long plate 14 is fixedly connected to the right wall of the tank 10, a pair of belt conveyors 15 are provided between the long plate 14 and the baffle plate 13 with holes, a temporary box 16 is provided on the front side of the belt conveyor 15, a hollow cylinder 17 is provided above the temporary box 16, and the hollow cylinder A plurality of suction holes 170 are provided on the side wall of 17. A disc 171 is fixedly connected to the right end of the hollow cylinder 17. A motor box 172 is fixedly connected to the right surface of the casing 1. A rotating motor 173 is installed in the motor box 172. The output shaft of the rotating motor 173 passes through the right wall of the casing 1 and is coaxially connected to the disc 171. An air pump 18 is installed in the casing 1. The air suction end of the air pump 18 is connected to an air suction pipe 180. The right end of the air suction pipe 180 is connected to an air suction box 181. The lower end of the air suction box 181 is tightly fitted with the inner wall of the hollow cylinder 17. Figure 2 As shown, the temporary box 16 is located in front of the front belt conveyor.

[0026] Working process: The aluminum evaporator 12 is operated to reduce the temperature inside the housing 1 to the quick-freezing temperature, and the granular food is temporarily placed in the box 16. After the food is placed, the rotating motor 173 and the suction pump 18 are operated. The rotating motor 173 drives the hollow cylinder 17 to rotate, and a negative pressure is formed in the suction box 181 connected to the suction end of the suction pump 18. Because the suction box 181 is tightly fitted with the inner wall of the hollow cylinder 17, the width of the suction box 181 is larger than the diameter of the suction hole 170 and smaller than the suction hole 170. The diameter of the suction hole 170 is twice that of the suction hole 170. Therefore, when the hollow cylinder 17 rotates, the suction holes 170 on its lower side wall pass under the suction box 181. The suction force generated by the suction holes 170 will make the granular food or other granular food overcome its own gravity and float up. Because the hole diameter is smaller than the diameter of the granular food, the granular food will stick to the lower side of the suction hole 170. Because the rotating motor 173 makes the hollow cylinder 17 rotate continuously, the suction holes that absorb the granular food will not float up. 170 will soon deviate from the bottom of the suction box 181. At this time, this row of suction holes 170 will lose the negative pressure, and the granular food will fall backward parabolically to the front belt conveyor 15 due to inertia and gravity because it has briefly adhered to the suction holes 170 and rotated around the axis of the hollow cylinder 17. When the granular food in this row falls onto the belt conveyor 15, the granular food adsorbed by the suction holes 170 in the next row will also reach the belt conveyor 15 after the above-mentioned movement process. When the granular food moves from the front belt conveyor 15 to the rear belt conveyor 15, the booster fan 11 below it will blow pressurized cold air from the bottom through the ventilation holes 152 to the top, and the granular food falling on the ventilation holes 152 will float in the air due to the wind. The strong cold wind blows on the food in the suspended state, and the frozen food is surrounded by cold wind in all directions to achieve rapid freezing of the food and form a monomer.

[0027] See also Figure 4 and Figure 5 On the basis of the above, it is further introduced that a long slide 140 is opened on the left surface of the long plate 14, and the front and rear side walls of the long slide 140 are connected to the short groove 141. The side wall of the long slide 140 is slidably connected to a long block 142, and the side wall of the short groove 141 is slidably connected to the short block 143. The long block 142 and the short block 143 are fixedly connected. The bottom wall of the machine slot 10 is fixedly connected to a hydraulic cylinder 144. The top of the telescopic rod inside the hydraulic cylinder 144 is fixedly connected to the long block 142, and the left surface of the short block 143 is rotatably connected to the roller inside the belt conveyor 15. The hydraulic cylinder 144 drives the belt conveyor 15 to move up and down a short distance, preventing the corn kernels from being pre-frozen and frozen on the conveyor belt in the belt conveyor 15, while also throwing the corn kernels into the air, increasing the contact area between the corn kernels and the cold air, and allowing the corn kernels to cool and condense faster.

[0028] See also Figure 4 and Figure 5, and considering that the granular food in the temporary storage box 16 closest to the hollow cylinder 17 will be adsorbed and create gaps, it is further introduced that the front surface of the short block 143 is fixedly connected with an L-shaped block 145, the upper surface of the L-shaped block 145 is fixedly connected to the temporary storage box 16, and the right surface of the temporary storage box 16 is slidably connected to the long plate 14. Since the L-shaped block 145 is fixedly connected to the short block 143 on one side, it will drive the temporary storage box 16 to move up and down, thereby causing the temporary storage box 16 to shake so that the corn kernels therein can always be laid flat, avoiding the formation of gaps in the area near the bottom of the hollow cylinder 17 due to the corn kernels being sucked away, which affects the efficiency of the suction hole 170 in sucking away the corn kernels later.

[0029] See also Figure 1 and Figure 2 It is worth mentioning that in order to facilitate the adjustment of the humidity in the quick-freezing machine and ensure the refrigeration effect, a water pump 19 is installed on the upper surface of the casing 1. The water outlet of the water pump 19 is connected to the main water pipe 190, and the front end of the main water pipe 190 is connected to a three-way valve 191. The right end of the three-way valve 191 is connected to a row of pipes 192. The lower side wall of the row of pipes 192 is connected to several moisturizing pipes 193. The lower end of the row of pipes 192 passes through the top wall of the casing 1 and is connected to an atomizing nozzle 194. The left end of the three-way valve 191 is connected to a defrost pipe 195. The defrost pipe 195 extends to the top of the all-aluminum evaporator 12, thereby being able to adjust the humidity in the casing 1 and ensuring the working efficiency of the all-aluminum evaporator 12.

[0030] See also Figure 2 and Figure 4 In addition, the left surface of the long board 14 is rotatably connected to a rotating rod 146, and a number of short rods 147 are fixedly connected to the side wall of the rotating rod 146. The end of the short rod 147 away from the rotating rod 146 is fixedly connected to a brush ball 148. When the belt conveyor 15 moves up and down, it will briefly contact the brush ball 148. The friction generated during the short contact will cause the rotating rod 146 to rotate, thereby causing the brush ball 148 to clean the conveyor belt. At the same time, it can also shovel up some granular food, increasing the contact area between some granular food and cold air.

[0031] See also Figure 6 and Figure 7 In order to ensure the energy saving of the quick freezer, an insulation layer 2 is provided on the outside of the casing 1, and a noise reduction layer 3 is provided on the outside of the insulation layer 2. Door slots 4 are provided on the front and rear surfaces of the casing 1. A sealing door 40 is hinged on the side of the door slot 4 away from the machine slot 10, and a collection box 160 is provided on the rear side of the rear belt conveyor 15, making the quick freezer more energy-saving and efficient.

[0032] See also Figure 1 and Figure 4 A thermometer 149 and a hygrometer 150 are installed on the left surface of the long board 14 mentioned above, and a display screen 151 is installed on the right surface of the casing 1, so that the staff can more conveniently observe the parameters of the quick-freezing machine and control the speed machine.

[0033] See also Figure 2 and Figure 6 In addition, a plurality of ventilation holes 152 are provided in the conveyor belt inside the belt conveyor 15. The apertures of the ventilation holes 152 and the suction holes 170 do not exceed 2 mm, ensuring that the granular food will not pass through the ventilation holes 152 or the suction holes 170, while also making it easier for the cold air to blow up the granular food.

[0034] When the food processing quick freezer of this embodiment is used, when granular fruits and vegetables or grains need to be quick-frozen after preliminary processing, the all-aluminum evaporator 12 is operated to reduce the temperature inside the casing 1 to the quick-freezing temperature, and the front sealing door 40 is opened to put the temporary box 16. The following will take the quick freezing of corn kernels as an example. After putting the food in, the rotating motor 173 and the suction pump 18 are operated, and the rotating motor 173 drives the hollow cylinder 17 to rotate, and a negative pressure is formed in the suction box 181 connected to the suction end of the suction pump 18. Because the suction box 181 is tightly fitted with the inner wall of the hollow cylinder 17, the width of the suction box 181 is greater than the diameter of the suction hole 170 but less than twice the diameter of the suction hole 170, so when the hollow cylinder 17 rotates, the row of suction holes 17 on its lower side wall When passing under the suction box 181, the suction force generated by the suction holes 170 will cause the corn kernels or other granular foods to float up due to their own gravity. Because the hole diameter is smaller than the diameter of the corn kernels, the corn kernels will stick to the lower side of the suction holes 170. Because the rotating motor 173 causes the hollow cylinder 17 to rotate continuously, the suction holes 170 that adsorb the corn kernels will soon deviate from the bottom of the suction box 181. At this time, this row of suction holes 170 will lose negative pressure, and the corn kernels will fall backward parabolically to the front belt conveyor 15 due to inertia and gravity. When the corn kernels in this row fall onto the belt conveyor 15, the corn kernels adsorbed by the suction holes 170 in the next row will also fall soon. The corn kernels will also be moved up and down by the hydraulic cylinder 144 so as to avoid the corn kernels from being frozen in advance on the conveyor belt in the belt conveyor 15. At the same time, the corn kernels will be thrown into the air to increase the contact area between the corn kernels and the cold air, so that the corn kernels can be cooled and condensed faster. The brush ball 148 provided at the bottom end of the short rod 147 on the rotating rod 146 will contact the conveyor belt from time to time due to the up and down movement of the belt conveyor 15, thereby driving the rotating rod 146 to rotate. The rotation of the rotating rod 146 will cause the brush ball 148 to continuously clean the surface of the conveyor belt when the conveyor belt moves, and will also shovel some corn kernels into the air. The short block 143 on the side is fixedly connected, so it will also drive the temporary storage box 16 to move up and down, so that the temporary storage box 16 can be shaken to keep the corn kernels therein flat, so as to avoid the area near the lowermost side of the hollow cylinder 17 therein being vacant due to the corn kernels being sucked away, which affects the efficiency of the suction hole 170 in sucking away the corn kernels later. When the corn kernels move from the front belt conveyor 15 to the rear belt conveyor 15, the booster fan 11 below it will blow pressurized cold air from below through the ventilation holes 152 to the top, and the corn kernels falling on the ventilation holes 152 will float in the air due to the wind force. The strong cold wind blows on the food in the suspended state, and the frozen food is surrounded by the cold wind in all directions, so as to realize the rapid freezing of the food and form a monomer, so that the frozen food is quickly cooled.Surface freezing, deep freezing, three stages. After the corn kernels are deep frozen, they will fall into the collection box 160 and wait to be taken away. When the quick freezer is running, if the temperature and humidity in the housing 1 fluctuate, the thermometer 149 and the hygrometer 150 will transmit the values to the display screen 151. At this time, the water pump 19 is started, the three-way valve 191 is opened, and water vapor is sprayed into the quick freezer from the atomizing nozzle 194. At the same time, warm water is also dripped onto the all-aluminum evaporator 12 through the defrosting pipe 195, which is convenient for further heating after the all-aluminum evaporator 12 is defrosted. The strong cooling effect is achieved, and the insulation layer 2 and the sealed door 40 also make the quick freezer more energy-efficient and environmentally friendly. Through the cooperation of the suction box 181, the suction hole 170, and the hollow cylinder 17, the granular food in the temporary storage box 16 is evenly transported to the belt conveyor 15 in rows, avoiding the granular food being transported to the belt conveyor 15 in a flat state with up and down squeezing. This increases the area of each food in contact with the cold air, enhances the quick freezing effect, and prevents the situation where some food is quickly frozen while others are not.
