Description

Technical Field

[0001] The present invention relates to the field of konjac slice processing, and particularly to an efficient slicing device and processing method for konjac slice processing. Background Art

[0002] As a raw material with a unique position in the food processing field, konjac has a special texture due to its rich glucomannan. In the process of konjac slice processing, the slicing link is crucial. However, the current slicing devices face at least the following problems: 1. Knife sticking problem: Konjac itself has high viscosity. When the slicing tool cuts it, the viscous substances of konjac are extremely easy to adhere to the surface of the tool. As the cutting continues, the konjac substances adhered to the tool gradually increase, which will not only affect the continuity of slicing, but also cause deviation in the thickness of subsequent slices; moreover, in order to clean the konjac adhered to the tool, the operator has to frequently stop the machine, which greatly reduces the production efficiency and increases the processing cost; 2. Slicing fragmentation problem: Since the texture of konjac is brittle and tender, if the slicing speed is too fast, it is easy to cause fracture; 3. Oxidation and discoloration problem: Since konjac contains rich polyphenolic substances, during the slicing process, once the konjac slices are exposed to the air, the polyphenolic substances on their surfaces will be rapidly oxidized under the action of polyphenol oxidase, resulting in the darkening of the color of the konjac slices. This oxidation and discoloration not only affect the appearance color of the konjac slices, greatly reducing their commercial value, but also may change the taste and nutritional components of the konjac slices.

The second water inlet and the second water outlet of the heat exchanger are connected with a color protection liquid circulation pipeline, and a second circulation pump and the recovery tank are installed on the color protection liquid circulation pipeline.

[0007] Preferably, an air cooling mechanism is further included. The air cooling mechanism includes a centrifugal fan, an air inlet pipe, an air outlet pipe and an air damper. The centrifugal fan is connected to the terminal part of the pre-cooling tunnel through the air inlet pipe, and the centrifugal fan is connected to the air damper through the air outlet pipe.

[0013] (III) Beneficial effects The beneficial effects of the present invention are as follows: 1. A pre-cooling tunnel is provided to pre-cool the konjac blocks before slicing. The glucomannan gum on the surface of the pre-cooled konjac blocks is slightly solidified, the hardness is increased, and the low temperature can reduce the gum viscosity of the konjac blocks, which can reduce the problems of knife sticking and slice breakage that may occur during slicing. And the cold quantity in the pre-cooling tunnel is utilized in the following ways: (1) Cooling the cooling coil, and using this part of the cold quantity to reduce the temperature of the cutting knife. After the cutting knife is cooled, the thermal viscosity of glucomannan in the konjac can be reduced, the probability of knife sticking can be further significantly reduced, and the low temperature makes the surface of the konjac gel slightly hardened, reducing the plastic deformation during cutting, and can further avoid the generation of fragments; (2) Cool the color protection liquid through a heat exchanger. The low-temperature color protection liquid can reduce the activity of polyphenol oxidase and slow down the oxidation rate of polyphenolic substances in konjac slices. The components in the color protection liquid (such as reducing agents like ascorbic acid) can react with oxygen preferentially, consume the oxygen in the surrounding environment, further prevent the oxidation of konjac slices, and significantly extend the time for them to remain unchanged in color. (3) Through the air-cooling mechanism, the excess cold in the pre-cooling tunnel is blown towards the slicing window direction. This can not only cool the blade and maintain the blade temperature at 5 - 10°C, but also cool the konjac block. The cold air evenly covers the surface of the konjac in the cutting area, inhibits oxidative browning and reduces blade sticking. Moreover, it can form an air curtain at the slicing window to prevent the color protection liquid sprayed by the spraying mechanism from detaching from the slicing chamber, which is beneficial for the recycling and utilization of the color protection liquid. 2. Set up a spraying mechanism. The spraying pump transports the color protection liquid in the recycling tank to the spraying pipe, and sprays the color protection liquid towards the slicing window direction through the spray nozzles on the spraying pipe. This can not only lubricate the blade and reduce the fragments caused by blade sticking, but also directly cover the fresh cut surface of the konjac slices with the color protection liquid, block the contact with oxygen, inhibit oxidation, and improve the product quality.

[0016] For better explaining the present invention for easy understanding, the present invention will be described in detail below in conjunction with the accompanying drawings through specific implementation manners.

[0017] Please refer to Figures 1 to 5 , the first embodiment of the present invention: An efficient slicing device for processing konjac slices includes a processing machine table 1, a feeding mechanism 2, a pre-cooling mechanism 3, a slicing mechanism 4, and a spraying mechanism 5; The feeding mechanism 2 is installed on the processing machine table 1, and the feeding mechanism 2 includes a lower conveyor belt 21 and an upper conveyor belt 22 arranged above the conveying terminal of the lower conveyor belt 21; The gap between the upper conveyor belt 22 and the lower conveyor belt 21 is the feeding gap, and the length of the lower conveyor belt 21 is greater than the length of the upper conveyor belt 22; The pre-cooling mechanism 3 includes a pre-cooling tunnel, and the pre-cooling tunnel is installed on the lower conveyor belt 21; The slicing mechanism 4 includes a slicing bin 41, a cutting knife 42, a driving assembly 43, a cooling coil 44, and a first circulation pump 45; The slicing bin 41 is arranged at the discharge port of the feeding gap, and a slicing window corresponding to the feeding gap is opened on the slicing bin 41; A cooling flow channel is arranged in the cutting knife 42, and the cooling flow channel is sequentially connected to the cooling coil 44 and the first circulation pump 45 through a pipeline to realize the circulation of the coolant; The cooling coil 44 is arranged in the pre-cooling tunnel; The driving assembly 43 is connected to the cutting knife 42 for driving the cutting knife 42 to rotate; The spraying mechanism 5 includes a recovery tank 51, a spraying pump 52, and a spraying pipe 53; The recovery tank 51 is arranged directly below the slicing bin 41, and a color protection liquid is stored in the recovery tank 51; The spraying pipe 53 is connected to the recovery tank 51 through the spraying pump 52; A plurality of spraying nozzles 54 are arranged on the spraying pipe 53, and the spraying nozzles 54 spray the color protection liquid towards the slicing window; During use, the konjac blocks to be cut enter the pre-cooling tunnel through the lower conveyor belt 21. The konjac blocks pass through the tunnel to achieve pre-cooling and temperature reduction. The glucomannan gum on the surface of the pre-cooled konjac blocks solidifies slightly, increasing the hardness. Moreover, the low temperature can reduce the gum viscosity of the konjac blocks. The pre-cooled konjac blocks enter the feeding gap, and under the combined conveyance of the upper conveyor belt 22 and the lower conveyor belt 21, the konjac blocks enter the cutting station of the slicing mechanism 4; the low-temperature environment in the pre-cooling tunnel is used to cool the ethylene glycol solution in the cooling coil 44. Under the action of the first circulation pump 45, the cooling fluid circulation is realized in the cooling flow channels inside the cutter 42. After the cutter 42 is cooled, it can reduce the thermal viscosity of glucomannan in the konjac, significantly reduce the probability of sticking to the knife, and the low temperature makes the surface of the konjac gel slightly hardened, reducing the plastic deformation during cutting and avoiding the generation of fragments. While the cutter 42 is cutting, the spraying pump 52 conveys the color protection liquid in the recovery tank 51 into the spraying pipe 53, and sprays the color protection liquid towards the slicing window through the spray nozzles 54 on the spraying pipe 53. This can not only lubricate the blade, reduce the fragments caused by sticking to the knife, but also directly cover the fresh cut surface of the konjac slices with the color protection liquid, block the contact with oxygen, inhibit oxidation, and improve the product quality.

[0018] As Figure 4 shown, in this embodiment, the driving assembly 43 includes a motor 431, a speed reducer 432, a driving gear 433, a driven gear 434, and a driving shaft 435; The driving shaft 435 is installed on the processing machine table 1 through bearings. Both ends of the driving shaft 435 are hermetically and rotationally connected with a coolant circulation pipeline. The cooling coil 44 and the first circulation pump 45 are both installed on the coolant circulation pipeline to form a coolant circulation; The cutter 42 is fixedly installed on the driving shaft 435; The motor 431 is connected to the driving gear 433 through the speed reducer 432; The driving gear 433 is meshed with the driven gear 434; The driven gear 434 is installed on the driving shaft 435; During use, the motor 431 drives the driving gear 433 to rotate through the speed reducer 432. The driving gear 433 drives the driving shaft 435 to rotate through the driven gear 434, and the driving shaft 435 drives the cutter 42 to rotate to achieve slicing.

[0019] As Figure 3 shown, in this embodiment, it further includes a heat exchanger 7. The first water inlet and the first water outlet of the heat exchanger 7 are both connected into the coolant circulation pipeline. The second water inlet and the second water outlet of the heat exchanger 7 are connected with a color protection liquid circulation pipeline, and a second circulation pump 56 and the recovery tank 51 are installed on the color protection liquid circulation pipeline; By setting up the heat exchanger 7, the cooling capacity of the pre-cooling tunnel can be further recovered. The coolant cooled in the cooling coil 44 is input into the heat exchanger 7 to cool the color protection liquid in the color protection liquid circulation pipeline, reducing the temperature of the color protection liquid. The low-temperature color protection liquid can reduce the activity of polyphenol oxidase and slow down the oxidation rate of polyphenolic substances in the konjac slices. The components in the color protection liquid (such as reducing agents like ascorbic acid) can react with oxygen preferentially, consuming the oxygen in the surrounding environment and further preventing the oxidation of the konjac slices, significantly extending the time for them not to change color.

[0020] Among them, the cutting knife 42 includes a cutter head and blades. A plurality of the blades are provided, and the plurality of blades are arranged in a circumferential array on the cutter head. A cooling flow channel in a continuously bent shape is arranged in the blade, and the cooling flow channels in adjacent blades are communicated with each other.

[0021] Please refer to Figures 1 to 5 , the second embodiment of the present invention: Based on the above first embodiment, as Figure 2 shown, this embodiment further includes an air-cooling mechanism 6. The air-cooling mechanism 6 includes a centrifugal fan 62, an air inlet pipe 61, an air outlet pipe 63, and an air damper 64; The centrifugal fan 62 is connected to the terminal part of the pre-cooling tunnel through the air inlet pipe 61, and the centrifugal fan 62 is connected to the air damper 64 through the air outlet pipe 63; The air damper 64 is arranged at the top of the inner wall of the slicing bin 41 and is directly above the slicing window; The air-cooling mechanism 6 can blow the excess cooling capacity in the pre-cooling tunnel towards the slicing window direction. It can not only cool the cutting knife, maintaining the temperature of the cutting knife at 5 - 10 °C, but also cool the konjac blocks. The cold air evenly covers the surface of the konjac in the cutting area, inhibiting oxidation and browning and reducing knife sticking. Moreover, it can form an air curtain at the slicing window to prevent the color protection liquid sprayed by the spraying mechanism 5 from escaping from the slicing bin 41, which is beneficial to the recycling and utilization of the color protection liquid.

[0022] As Figure 5 shown, in this embodiment, a separation net 55 is arranged in the recovery box 51, and the liquid level of the color protection liquid is higher than the separation net 55. The spraying pipe 53 transports the color protection liquid below the separation net 55 to the spraying nozzle 54; During use, the sliced konjac slices fall on the separation net 55 and are immersed in the color protection liquid to avoid oxidation. The setting of the separation net 55 can prevent the sliced konjac slices from affecting the transportation of the color protection liquid by the spraying pump 52.

[0023] In this embodiment, the feeding mechanism 2 further includes a lifting component. The lifting end of the lifting component is connected to the upper conveyor belt 22, and by adjusting the height of the upper conveyor belt 22, the feeding of konjac blocks of different sizes is realized.

[0024] In this embodiment, the lower conveyor belt 21 is a stainless steel mesh belt conveyor, and the cooling coil 44 is arranged below the stainless steel mesh belt conveyor. The cold air in the pre-cooling tunnel can pass through the stainless steel mesh belt conveyor to cool the cooling coil 44 below.

[0025] Please refer to Figures 1 to 5 , the third embodiment of the present invention: A processing method of an efficient slicing device for processing konjac slices. On the basis of the above-mentioned first embodiment, this embodiment includes the following steps: S1: The konjac blocks enter the pre-cooling tunnel through the lower conveyor belt 21. The konjac blocks pass through the tunnel to achieve pre-cooling and temperature reduction.

[0026] Among them, the glucomannan gum on the surface of the pre-cooled konjac blocks is slightly solidified, the hardness is increased, and the low temperature can reduce the gum viscosity of the konjac blocks.

[0027] S2: The cold-treated konjac blocks enter the feeding gap. Under the combined transportation of the upper conveyor belt 22 and the lower conveyor belt 21, the konjac blocks enter the cutting station of the slicing mechanism 4. The low-temperature environment in the pre-cooling tunnel is used to cool the ethylene glycol solution in the cooling coil 44. Under the action of the first circulation pump 45, the cooling fluid circulation is realized in the cooling flow channels inside the cutter 42.

[0028] Among them, after the cutter 42 is cooled, it can reduce the thermal viscosity of glucomannan in konjac, significantly reduce the probability of sticking to the knife, and the low temperature makes the surface of the konjac gel slightly hardened, reducing the plastic deformation during cutting and avoiding the generation of fragments.

[0029] S3: While the cutter 42 is cutting, the spray pump 52 transports the color protection liquid in the recovery tank 51 into the spray pipe 53, and sprays the color protection liquid towards the slicing window through the spray nozzles 54 on the spray pipe 53.
