Description

Technical Field

[0001] This utility model relates to the field of French fry processing technology, and in particular to a quick-freezing machine for French fry processing. Background Technology

[0002] A quick-freezing machine is a device used to rapidly freeze foods such as French fries. It quickly cools and freezes French fries in a low-temperature environment to maintain their appearance, taste, and nutritional components, while extending their shelf life.

[0003] When using a quick-freezing machine to quick-freeze French fries, the fries are placed on a perforated conveyor belt. The first motor is then started, driving a rotating shaft to move the conveyor belt and transport the fries into the quick-freezing machine. The machine's internal cold air system then cools the air. This system compresses the refrigerant, releasing heat in the condenser, and then reduces its pressure and temperature through an expansion valve. The refrigerant absorbs heat from the air in the evaporator, further lowering the air temperature. A fan inside the machine circulates the cold air, and a temperature control system precisely regulates the temperature to maintain a low environment. This circulation of cold air within the machine achieves the desired quick-freezing effect for the French fries. Because the fries are usually washed before quick-freezing to remove excess starch, the remaining moisture can cause them to stick together during freezing. This can lead to breakage during later use, increasing thawing time and reducing processing efficiency. Utility Model Content

[0004] The technical problem this invention aims to solve is that French fries usually need to be washed before quick-freezing to remove excess starch. However, after washing, the surface of the French fries will still have moisture attached. As a result, when the French fries are stacked together, they are prone to sticking together during quick-freezing. This can easily cause the French fries to break during later use, increasing the thawing time and reducing the efficiency of subsequent processing.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a quick-freezing machine for processing French fries, including a quick-freezing machine body, in which round shafts are symmetrically installed through the inner wall of the quick-freezing machine body, and a first motor is fixedly installed on one side of the quick-freezing machine body. The output end of the first motor is fixedly connected to one side of one of the round shafts by means of a coupling. A perforated conveyor belt is sleeved on the outer surface of the two round shafts. An auxiliary device is provided on the inner wall of the quick-freezing machine body. The auxiliary device can drive several sprocket rods and fan blades through a drive mechanism to lift the French fries conveyed on the perforated conveyor belt to avoid the phenomenon of quick-freezing sticking. At the same time, it works in conjunction with a striking mechanism to strike and vibrate the inner wall of the perforated conveyor belt to prevent the phenomenon of quick-freezing sticking.

[0006] The aforementioned components achieve the following effect: During the production and processing of French fries, when the main body of the quick-freezing machine is used to quick-freeze the French fries, the French fries are placed on a perforated conveyor belt. Then, the first motor is started to drive the rotating shaft, which in turn drives the perforated conveyor belt to transport the French fries into the interior of the quick-freezing machine. The cold air system inside the quick-freezing machine is then activated to cool the air. This cold air system releases heat in the condenser by compressing the refrigerant, and then reduces its pressure and temperature through the expansion valve, allowing the refrigerant to absorb heat from the air in the evaporator. The process involves lowering the air temperature, while the fan inside the freezer circulates the cold air. The temperature control system precisely regulates the temperature to ensure the environment remains at a low temperature. This circulation of cold air within the freezer quickly freezes the fries. After the fries are conveyed into the freezer via a perforated conveyor belt, an auxiliary device can be activated to lift the fries while simultaneously vibrating the conveyor belt to prevent them from sticking together. This avoids affecting later use, reduces thawing time, and improves subsequent processing efficiency.

[0007] Preferably, the auxiliary device includes several sprocket rods, wherein the two ends of the sprocket rods are respectively installed through and on both sides of the inner wall of the quick-freezing machine body, and several fan blades are fixedly installed on the outer surface of the sprocket rods; a striking mechanism, wherein the striking mechanism is located inside the quick-freezing machine body in the inner wall of the perforated conveyor belt, and is used to strike the inside of the perforated conveyor belt; and a driving mechanism, wherein the driving mechanism is located between the several sprocket rods and the striking mechanism, and is used to drive the several sprocket rods to rotate and the striking mechanism to operate.

[0008] The effects achieved by the above-mentioned components are as follows: By setting up auxiliary devices, after the perforated conveyor belt transports the French fries into the interior of the quick-freezing machine, the drive mechanism is activated to drive several sprockets and fan blades to rotate. The rotation direction is opposite to the movement direction of the perforated conveyor belt, which lifts the conveyed French fries and prevents them from piling up during quick-freezing. At the same time, the striking mechanism can make the French fries vibrate on the surface of the perforated conveyor belt, making them less likely to stick to the perforated conveyor belt during quick-freezing. This effectively prevents the French fries from sticking together during quick-freezing, making them easier to use later, reducing the probability of breakage, shortening the thawing time, and improving the efficiency of subsequent processing.

[0009] Preferably, the longitudinal section of the fan blade is arc-shaped, and the surface of the fan blade is hollowed out.

[0010] The effect achieved by the above-mentioned components is that by setting the fan blades to an arc shape, they can scoop up the fries when lifting them, and at the same time, the open shape does not hinder the contact between air and the fries, thus improving the quick-freezing efficiency.

[0011] Preferably, the striking mechanism includes a round rod, which is disposed inside the hollow conveyor belt and has its two ends respectively installed through and on both sides of the inner wall of the quick-freezing machine body; and a plurality of striking rods, wherein the inner wall of the striking rod is sleeved and installed on the outer surface of the round rod.

[0012] The effect achieved by the above-mentioned components is as follows: by setting up a striking mechanism, when the drive mechanism drives the round rod to rotate back and forth intermittently, it can drive several striking rods on the outer surface to strike back and forth in the inner wall of the hollow conveyor belt, causing the hollow conveyor belt to vibrate, preventing the French fries from sticking to the hollow conveyor belt during the quick-freezing process, and at the same time, it can also vibrate the stacked conveyor belts apart.

[0013] Preferably, protective blocks are fixedly installed on the outer surface of both striking points of the striking rod, and the protective blocks are made of rubber.

[0014] The effect achieved by the above components is that by setting up protective blocks, the contact wear between the two ends of the striking rod and the inner wall of the hollow conveyor belt can be reduced, making it less prone to damage during the striking process and improving the service life of both.

[0015] Preferably, reinforcing rods are symmetrically fixedly installed on both sides of the striking rod, and one side of the reinforcing rod is fixedly installed on the outer surface of the round rod.

[0016] The effect achieved by the above components is that by setting up reinforcing rods, the connection area between the striking rod and the round rod can be increased, making the connection more secure and stable, and less prone to damage.

[0017] Preferably, the drive mechanism includes a second motor, one side of which is fixedly mounted on one side of the blast freezer body, and its output end is fixedly connected to one side of one of the sprocket rods via a coupling; two first chains, each sleeved on the outer surface of one of the three sprocket rods, and connected in series in pairs; a sprocket sector gear, one end of which is rotatably mounted on one side of the blast freezer body; a second chain, the inner walls of both ends of which are respectively sleeved on the outer surface of one end of the sprocket sector gear and the outer surface of one end of one of the sprocket rods; a circular gear, one side of which is fixedly mounted on one side of the striking rod, and its outer surface meshes with the outer surface of the sprocket sector gear; and a torsion spring, the inner wall of which is sleeved on the outer surface of the circular rod, and its two ends are respectively fixedly mounted on one side of the circular gear and one side of the blast freezer body.

[0018] The effect achieved by the above components is as follows: By setting up a drive mechanism, when the French fries are quick-frozen, the second motor can be started to drive one of the sprocket rods to rotate. Then, under the transmission of the first chain, the other two sprocket rods can be driven to rotate. At the same time, under the transmission of the second chain, the sprocket sector gear can be driven to rotate, which in turn drives the circular gear to rotate. At this time, the torsion spring deforms, thereby driving the circular rod and several striking rods to rotate to a certain angle, so that their two ends strike the inner walls of the perforated conveyor belt. When the sprocket sector gear is completely removed from the circular gear, the torsion spring will drive the circular rod and the circular gear to reset, so that the two ends of the striking rods move in opposite directions to strike the inner walls of the perforated conveyor belt. This achieves the effect of driving the circular rod and striking rods to move left and right intermittently inside the perforated conveyor belt to strike.

[0019] Preferably, the drive mechanism further includes a protective cover, one side of which is fixedly installed on one side of the quick-freezing machine body and covers the first chain, the second chain, the sprocket sector gear and the circular toothed plate.

[0020] The effect achieved by the above components is that by setting up protective covers, the first chain, the second chain, the sprocket sector gear, and the circular toothed plate can be covered, so that they are less likely to be accidentally touched during use, thus avoiding injury, and at the same time reducing contact with air to prevent corrosion and aging.

[0021] The beneficial effects of this utility model are:

[0022] By setting up auxiliary devices, after the perforated conveyor belt transports the French fries into the main body of the quick-freezing machine, the drive mechanism is activated to drive several sprockets and fan blades to rotate in the opposite direction to the movement of the perforated conveyor belt. This lifts up the conveyed French fries, preventing them from piling up during quick-freezing. At the same time, the striking mechanism causes the French fries to vibrate on the surface of the perforated conveyor belt, making them less likely to stick to the conveyor belt during quick-freezing. This effectively prevents the French fries from sticking together during quick-freezing, making them easier to use later, reducing the probability of breakage, shortening the thawing time, and improving the efficiency of subsequent processing.

[0031] Figs. 1-4The illustrated quick-freezing machine for processing French fries includes a quick-freezing machine body 1. Round shafts 3 are symmetrically installed through the inner wall of the quick-freezing machine body 1. A first motor 5 is fixedly installed on one side of the quick-freezing machine body 1. The output end of the first motor 5 is fixedly connected to one side of one of the round shafts 3 via a coupling. A perforated conveyor belt 4 is fitted onto the outer surface of the two round shafts 3. An auxiliary device 2 is provided on the inner wall of the quick-freezing machine body 1. The auxiliary device 2 can drive several sprocket rods 21 and fan blades 22 via a drive mechanism 23 to lift the French fries conveyed on the perforated conveyor belt 4 to prevent them from sticking together during quick-freezing. It also works in conjunction with a striking mechanism 24 to strike and vibrate the inner wall of the perforated conveyor belt 4 to further prevent sticking during quick-freezing. During the production and processing of French fries, when the main body 1 of the quick-freezing machine is used to quick-freeze the French fries, the French fries are placed on the perforated conveyor belt 4. Then, the first motor 5 is started to drive the circular shaft 3 to rotate, thereby driving the perforated conveyor belt 4 to convey the French fries into the interior of the quick-freezing machine 1. Then, the cold air system inside the quick-freezing machine 1 is activated to cool the air. This cold air system compresses the refrigerant to release heat in the condenser, and then reduces its pressure and temperature through the expansion valve, allowing the refrigerant to absorb heat from the air in the evaporator, thus lowering the air temperature. The cold air inside the main body 1 of the quick-freezing machine is circulated by a fan, and the temperature control system precisely regulates the temperature to ensure that the environment remains at a low temperature. The cold air is circulated and quick-frozen inside the main body 1, thereby achieving the effect of quick-freezing the French fries. After the French fries are conveyed into the main body 1 by the perforated conveyor belt 4, the auxiliary device 2 can be activated to lift the conveyed French fries and at the same time tap and vibrate the perforated conveyor belt 4 to prevent the French fries from sticking together, thus avoiding affecting later use, reducing the thawing time, and improving the efficiency of later processing.

[0032] Figs. 1-4The auxiliary device 2 shown includes several sprocket rods 21, with both ends of the sprocket rods 21 respectively penetrating and installed on both sides of the inner wall of the quick-freezing machine body 1, and several fan blades 22 fixedly installed on the outer surface of the sprocket rods 21; a striking mechanism 24, which is located inside the quick-freezing machine body 1 in the inner wall of the hollow conveyor belt 4, and is used to strike the inside of the hollow conveyor belt 4; and a driving mechanism 23, which is located between the several sprocket rods 21 and the striking mechanism 24, and is used to drive the several sprocket rods 21 to rotate and the striking mechanism 24 to run. By setting up auxiliary device 2, after the French fries are conveyed into the body 1 of the quick-freezing machine by the perforated conveyor belt 4, the drive mechanism 23 is activated to drive several sprocket rods 21 and fan blades 22 to rotate. The rotation direction is opposite to the movement direction of the perforated conveyor belt 4, lifting the conveyed French fries to prevent them from piling up during quick-freezing. At the same time, the striking mechanism 24 causes the French fries to vibrate on the surface of the perforated conveyor belt 4, making them less likely to stick to the perforated conveyor belt 4 during quick-freezing. This effectively prevents the French fries from sticking together during quick-freezing, making them easier to use later, reducing the probability of breakage, shortening the thawing time, and improving the efficiency of subsequent processing. The longitudinal section of the fan blades 22 is arc-shaped, and the surface of the fan blades 22 is perforated. By setting the fan blades 22 to be arc-shaped, they can scoop up the French fries during the lifting operation, and the perforated state does not hinder air contact with the French fries, improving the quick-freezing efficiency.

[0033] Figs. 1-4 The striking mechanism 24 shown includes a round rod 241, which is disposed inside the perforated conveyor belt 4, with both ends respectively penetrating and installed on both sides of the inner wall of the quick-freezing machine body 1; and several striking rods 242, wherein the inner wall of the striking rods 242 is sleeved on the outer surface of the round rod 241. By setting the striking mechanism 24, when the driving mechanism 23 drives the round rod 241 to rotate back and forth intermittently, it can drive the several striking rods 242 on the outer surface to strike back and forth in the inner wall of the perforated conveyor belt 4, causing the perforated conveyor belt 4 to vibrate, preventing the French fries from sticking to the perforated conveyor belt 4 during the quick-freezing process, and also vibrating apart the stacked conveyor belts.

[0034] Figs. 1-4 Protective blocks 243, made of rubber, are fixedly installed on the outer surface of both striking points of the striking rod 242. By installing the protective blocks 243, the contact wear between the striking rod 242 and the inner wall of the perforated conveyor belt 4 can be reduced, making it less prone to damage during striking and extending the service life of both. Reinforcing rods 244 are symmetrically fixedly installed on both sides of the striking rod 242, with one side of the reinforcing rod 244 fixedly installed on the outer surface of the round rod 241. By installing the reinforcing rods 244, the connection area between the striking rod 242 and the round rod 241 can be increased, making the connection more secure and stable, and less prone to damage.

[0035] Figs. 1-4 The drive mechanism 23 shown includes a second motor 231, one side of which is fixedly mounted on one side of the quick-freezing machine body 1, and its output end is fixedly connected to one side of one of the sprocket rods 21 via a coupling; two first chains 232, each of which is sleeved on the outer surface of the three sprocket rods 21 and connected in series in pairs; a sprocket sector gear 234, one end of which is rotatably mounted on one side of the quick-freezing machine body 1; and a second chain 233, which... The inner walls of the two ends of the second chain 233 are respectively fitted onto the outer surface of one end of the sprocket sector gear 234 and the outer surface of one end of one sprocket rod 21; a circular gear 235, wherein one side of the circular gear 235 is fixedly installed on one side of the striking rod 242, and its outer surface meshes with the outer surface of the sprocket sector gear 234; a torsion spring 236, wherein the inner wall of the torsion spring 236 is fitted onto the outer surface of the circular rod 241, and both ends are respectively fixedly installed on one side of the circular gear 235 and one side of the quick-freezing machine body 1. By setting up a drive mechanism 23, when the French fries are quick-frozen, the second motor 231 can be started to drive one of the sprocket rods 21 to rotate. Then, under the transmission of the first chain 232, the other two sprocket rods 21 can be driven to rotate. At the same time, under the transmission of the second chain 233, the sprocket sector gear 234 can be driven to rotate, which in turn drives the circular gear 235 to rotate. At this time, the torsion spring 236 deforms, which drives the circular rod 241 and several striking rods 242 to rotate to a certain angle, so that their two ends strike the inner walls of the hollow conveyor belt 4 respectively. When the sprocket sector gear 234 is completely removed from the circular gear 235, the torsion spring 236 will drive the circular rod 241 and the circular gear 235 to reset, so that the two ends of the striking rods 242 move in opposite directions to strike the inner walls of the hollow conveyor belt 4. This achieves the effect of driving the circular rod 241 and the striking rods 242 to move left and right intermittently inside the hollow conveyor belt 4 to strike. The drive mechanism 23 also includes a protective cover 237, one side of which is fixedly mounted on one side of the quick-freezing machine body 1, covering the first chain 232, the second chain 233, the sprocket sector gear 234, and the circular toothed plate. By providing the protective cover 237, the first chain 232, the second chain 233, the sprocket sector gear 234, and the circular toothed plate can be covered, making them less likely to be accidentally touched during use, thus avoiding injury, and also reducing contact with air to prevent corrosion and aging.

[0036] Working principle: During the processing of French fries, when the main body 1 of the quick-freezing machine is used to quick-freeze the fries, the fries are placed on the perforated conveyor belt 4. Then, the first motor 5 is started to drive the circular shaft 3 to rotate, which in turn drives the perforated conveyor belt 4 to convey the fries into the interior of the quick-freezing machine 1. Then, the cold air system inside the quick-freezing machine 1 is activated to cool the air. This cold air system compresses the refrigerant to release heat in the condenser, and then reduces its pressure and temperature through the expansion valve, allowing the refrigerant to absorb heat from the air in the evaporator, thus lowering the air temperature. The fan inside the main body 1 of the quick-freezing machine circulates cold air, and the temperature control system precisely regulates the temperature to ensure that the environment remains at a low temperature. This circulation of cold air within the main body 1 achieves the effect of quick-freezing the French fries. After the French fries are conveyed into the main body 1 by the perforated conveyor belt 4, the second motor 231 is started, driving one of the sprocket rods 21 and fan blades 22 to rotate. Then, driven by the first chain 232, the other two sprocket rods 21 and fan blades 22 rotate in the opposite direction to the movement of the perforated conveyor belt 4, lifting the conveyed French fries. To prevent accumulation during quick-freezing, when one of the sprocket rods 21 and the fan blade 22 rotates, under the transmission of the second chain 233, it can drive the sprocket sector gear 234 to rotate, which in turn drives the circular gear 235 to rotate. At this time, the torsion spring 236 deforms, thereby driving the circular rod 241 and several striking rods 242 to rotate to a certain angle, so that their two ends strike the inner walls of the perforated conveyor belt 4 respectively. When the sprocket sector gear 234 is completely removed from the circular gear 235, the torsion spring 236 will drive the circular rod 241 and the circular gear 235 to reset, so that the two ends of the striking rods 242 strike the inner walls of the perforated conveyor belt 4 respectively. The ends move in opposite directions, striking the inner walls of the perforated conveyor belt 4. This causes the round rod 241 and the striking rod 242 to move intermittently left and right inside the perforated conveyor belt 4, causing it to vibrate. This prevents the fries from sticking to the perforated conveyor belt 4 during quick-freezing. It also vibrates apart stacked conveyor belts, making it less likely for the fries to stick to the perforated conveyor belt 4 during quick-freezing. This effectively prevents the fries from sticking together during quick-freezing, making them easier to use later, reducing the probability of breakage, shortening the thawing time, and improving the efficiency of subsequent processing.
