Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dehydration and separation, and particularly relates to a dehydration and separation device and processing method for instant dried squid. BACKGROUND

[0002] In the field of dehydration of instant dried squid, hot air devices or oven devices are usually used to dry the squid, that is, heat is supplied below a water conveying belt or hot air is blown to dry the squid, and continuous heat causes the materials on the conveying belt to be naturally dehydrated and dried. Since the instant dried squid is laid flat on the conveying belt, the heating is not uniform when the hot air is dried. High-protein foods such as squid are prone to adhesion due to protein denaturation during the drying process. The one-way pushing mechanism of the traditional equipment cannot effectively break up the clumps, resulting in local overheating and burnt paste, which affects the taste and safety of the product. SUMMARY

[0003] The present application aims to provide a dehydration device and processing method for instant dried squid to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] To solve the above technical problems, the technical solution adopted by the present application is as follows:

[0005] Firstly, the present application provides a dehydration and separation device for instant dried squid, comprising:

[0006] A rotating drum, which is a cylindrical metal shell with a smooth inner wall, has a feeding port and a discharging port at two ends respectively;

[0007] A screw pushing device, which comprises a screw shaft and a screw blade arranged on the screw shaft, is installed in the rotating drum, the screw shaft is coaxially arranged with the main shaft of the rotating drum, and the screw blade has a gap with the inner wall of the rotating drum;

[0008] A first motor is connected with the main shaft of the rotating drum through a rigid coupling;

[0009] A second motor is connected with the transmission shaft of the screw pushing device through a differential mechanism, and is used to adjust the speed difference and the forward and reverse rotation between the screw pushing device and the rotating drum;

[0010] A torque sensor is installed on the transmission shaft of the screw pushing device to monitor the torque change of the screw pushing device in real time;

[0011] A hot air circulation device, which has a first hot air pipeline and a second hot air pipeline, is connected with the two ends of the rotating drum respectively, and forms a directional air flow of hot air between the rotating drum and the hot air circulation device, and the first hot air pipeline and the second hot air pipeline are respectively provided with temperature sensors.

[0012] Compared with the traditional, the dehydration separation equipment provided by the application adjusts the speed difference and the forward and reverse rotation between the spiral pusher and the rotating drum through the second motor and the differential, the second motor and the differential enable the rotating drum and the spiral pusher to realize forward and reverse rotation switching, that is, positive and negative differential ratio switching, so that the rubber sheet automatically reciprocates in the rotating drum, avoids the uneven residence time caused by one-way conveying, and improves the drying uniformity.

[0013] The rotating drum and the spiral pusher provided by the application adopt a differential to build a double-flipping mechanism, the first motor is connected with the main shaft of the rotating drum through a rigid coupling, so that the rubber sheet rolls in the rotating drum, and the second motor is connected with the transmission shaft of the spiral pusher through the differential and rotates at a speed lower than that of the rotating drum, so as to realize the pushing and flipping of the rubber sheet, the planetary gear differential can adjust the speed ratio between the rotating drum and the spiral pusher, ensure the relative movement coordination of the spiral pusher and the rotating drum, avoid extrusion, promote the penetration of hot air, and reduce the damage of the rubber sheet.

[0014] The torque sensor provided by the application monitors the pushing resistance (reflecting the amount and water content change of the rubber sheet) in real time, adjusts the output of the second motor, and ensures the stability of the differential ratio, when the water content of the rubber sheet is high and the viscosity is large, the torque increases, the rotating speed of the second motor is increased, and the rotation of the pusher due to resistance is avoided. Compared with the traditional independent control which needs to manually preset multiple groups of rotating speed parameters and cannot respond to real-time load changes, the rotating drum may be idling, the pusher may be stuck, or the rubber sheet may be damaged. According to the dynamic adjustment of the rotating speed of the rotating drum and the spiral pusher according to the water content of the rubber sheet, the dehydration uniformity is effectively improved.

[0015] As an extension of the above-mentioned scheme, the differential is a planetary gear differential, which includes a sun gear, a planet gear, a ring gear and a planet carrier, the planet gear is located between the sun gear and the ring gear and is connected with the planet carrier, the first motor is in transmission connection with the sun gear, the second motor inputs power through the ring gear, and the planet carrier is in transmission connection with the spiral pusher.

[0016] The extension scheme is in transmission connection with the rotating drum and the spiral pusher through the planetary gear differential, the first motor drives the sun gear, the second motor drives the ring gear, the planet carrier outputs to the spiral pusher, and a differential transmission chain with double inputs and single output is formed, when the second motor rotates in reverse, a negative differential ratio (the spiral pusher and the rotating drum rotate in opposite directions) is output, and the bidirectional movement of the spiral pusher is realized.

[0017] As an extension of the above-mentioned scheme, infrared sensors are arranged at the inlet and outlet of the rotating drum respectively, for monitoring the position of the rubber sheet in the dehydration stage in real time.

[0018] When the infrared sensor at the discharge port detects the rubber, the second motor switches the rotation direction between the screw conveyor and the rotating drum, so that the rotating drum rotates in the opposite direction of the screw conveyor, the differential speed ratio is negative, and reverse pushing is started;

[0019] When the infrared sensor at the discharge port detects the rubber, the second motor switches the rotation direction between the screw conveyor and the rotating drum, so that the rotating drum rotates in the opposite direction of the screw conveyor, the differential speed ratio is negative, and reverse pushing is started;

[0020] The extended scheme monitors the position of the rubber at the inlet and outlet of the rotating drum through an infrared sensor, triggers reverse pushing in advance, avoids the accumulation of rubber at the end of the rotating drum, and sudden increase of resistance of the screw conveyor. Compared with the passive response of the torque sensor, it can reduce the overload impact, and the traditional mechanical limit switch needs to be triggered by the contact of the rubber, which is easy to cause the end to be too thick.

[0021] As an extension of the above scheme, the hot air circulating device comprises:

[0022] A hot air generator is arranged for providing hot air;

[0023] A circulating fan is arranged for blowing the hot air to one end of the rotating drum through the first hot air pipeline. The hot air flows through the turned rubber and takes away the moisture when it contacts the surface of the rubber. The hot air flows out from the other end of the rotating drum and returns to the hot air circulating device through the second hot air pipeline, forming a directional air flow of hot air. A moisture absorption filter layer is arranged at the connection between the second hot air pipeline and the hot air circulating device.

[0024] In the extended scheme, the rubber moves back and forth in the rotating drum, contacts the hot air multiple times, reduces the moisture content deviation, and greatly improves the product quality consistency. At the same time, hot air at 40-65°C is introduced into the rotating drum, so that the hot air is uniformly distributed and penetrates the turned rubber, effectively shortening the drying time and improving the production efficiency. The moisture absorption filter layer is used to absorb the moisture brought out by the hot air in the second hot air pipeline, so as to ensure the dryness of the hot air for recycling.

[0025] As an extension of the above scheme, the temperature sensor comprises a first temperature sensor arranged in the first hot air pipeline and a second temperature sensor arranged in the second hot air pipeline, for acquiring the first hot air temperature and the second hot air temperature at both ends of the rotating drum;

[0026] When the temperature difference between the first hot air temperature and the second hot air temperature is greater than a pre-set temperature difference threshold, the hot air generator is controlled to increase the power to increase the hot air temperature and / or the circulating fan is controlled to increase the hot air flow.

[0027] The extended scheme is based on temperature difference control of hot air temperature and hot air volume, solves the problem of uneven temperature distribution in traditional hot air drying, in the traditional equipment, the hot air enters from one end of the rotating drum, due to the factors of material blockage, airflow attenuation, etc., the inlet end temperature is high (up to 70℃), the outlet end temperature is low (as low as 40℃), the temperature difference exceeds 20℃, which causes uneven drying of the material. The extended scheme automatically controls the hot air generator to increase the power to increase the hot air temperature and / or controls the circulating fan to increase the hot air volume, reduces the moisture content deviation of the rubber.

[0028] Secondly, the application provides a processing method of instant rubber, which comprises the following steps:

[0029] Step one: pretreat the dried cylindrical rubber, which includes thawing, rinsing the surface and inner wall, and cutting into blocks or sheets;

[0030] Step two: send the cut rubber into the soaking pool formed by multiple stages in series, purify the water body in real time through the water circulation filter pipeline, keep the water temperature at 20-25℃, after soaking is completed, the rubber is lifted from the soaking pool by the mesh belt conveyor, and in the transmission process, the rubber is washed by setting a high-pressure spray head to remove the residual soaking liquid on the surface;

[0031] Step three: the rubber enters the dehydration separation equipment of instant rubber according to the above technical scheme, and is dehydrated at a hot air temperature of 40-65℃ and a hot air volume of 800-1200 m³ / h, the dehydrated rubber falls on the vibrating dewatering conveyor, and the surface free moisture is removed through vibration of 5-10mm amplitude, and the infrared moisture detector at the end of the vibrating dewatering conveyor monitors in real time to ensure that the moisture content of the rubber is ≤30%;

[0032] Step four: the vibrating dewatering conveyor sends the rubber into the paddle type mixing conveyor, and a quantitative pump injects preheated seasoning liquid at 60-70℃, the paddle stirs at a rotating speed of 30-50rpm to make the rubber evenly coated with the liquid;

[0033] Step five: the mixed rubber is sent into the continuous sterilization kettle through the sterile pipeline, sterilized at 121℃ for 15min, and then enters the counter-pressure cooling tunnel, the water temperature of the counter-pressure cooling tunnel decreases from 80℃ to 40℃, and the center temperature of the rubber decreases to 40℃;

[0034] Step six: the sterilized rubber falls into the filling part, and then is filled, packaged, detected, and stored in the warehouse.

[0035] The technical scheme realizes precise control and efficient connection of multiple links such as thawing and cleaning, cutting and soaking, dehydration and seasoning, and sterilization and packaging, guarantees the nutrition and taste of the fish glue, effectively removes fishy smell and impurities, greatly improves production efficiency, reduces manual intervention, and realizes the industrial production goal of stable quality, high efficiency and energy saving.

[0036] As an extension of the above scheme, in the third step:

[0037] In the starting stage of the fish glue entering the dehydration and separation equipment, the first motor starts the rotation of the rotating drum at a set first rotating speed, and the second motor drives the screw pusher at a second rotating speed through the differential mechanism, and the differential ratio of the first rotating speed and the second rotating speed is 1.2-2.5:1.

[0038] In the dehydration stage, the second motor adjusts the second rotating speed in real time according to the torque feedback of the torque sensor, maintains the differential ratio set in the current process, and ensures that when the first rotating speed of the rotating drum decreases due to the increase of the load, the differential mechanism synchronously reduces the second rotating speed of the screw pusher, so as to avoid the accumulation of the fish glue due to the mismatch of the speeds of the two.

[0039] The technical scheme realizes real-time monitoring of load changes through the torque sensor, dynamically adjusts the rotating speed of the screw pusher by driving the second motor, even if the rotating speed of the rotating drum decreases due to the viscosity or accumulation of the fish glue, the pusher can also be reduced in speed synchronously, the speed matching of the two is maintained, the material accumulation and blockage are prevented, the running stability and production efficiency of the equipment are improved, and the uniform transportation and heating of the fish glue in the rotating drum are guaranteed, the drying uniformity is increased, and the product quality and production benefit are effectively improved.

[0040] As an extension of the above scheme, the torque sensor collects the real-time torque value of the transmission shaft of the screw pusher at a frequency of 100 Hz, and transmits it to the controller for processing, the controller sets a normal working torque threshold value in advance, and the controller performs the following processing steps:

[0041] When the real-time torque value exceeds the upper threshold value, it indicates that the push resistance increases due to the viscosity or accumulation of the fish glue, and the controller sends an acceleration instruction to the second motor;

[0042] When the real-time torque value is lower than the lower threshold value, it indicates that the water content of the fish glue has been reduced to a low level or the feed amount is too small or the material in the rotating drum is sparse, the drying is easy to push, the push resistance decreases, and the torque decreases, and the controller sends a speed reduction instruction to the second motor, which saves energy on the premise of ensuring the dehydration effect, avoids over-drying or idling of the material, and realizes dynamic adjustment.

[0043] The extended scheme accurately deals with the complex working conditions in the drying process of fish glue by 100Hz high-frequency sampling and intelligent threshold judgment mechanism, effectively solving the problems of material blockage, energy waste and unstable quality existing in traditional equipment. The embodiment can adapt to the moisture content difference of different batches of fish glue, realize real-time optimization of production parameters, improve drying uniformity and product qualification rate.

[0044] As an extension of the above scheme, the processing method comprises a hot air temperature segmented control step:

[0045] Pre-drying control, when the first rotating speed of the rotating drum is 18-20r / min and the second rotating speed of the screw pusher is 10-11r / min, the hot air temperature is controlled to be 60-65℃, the hot air volume is 1000-1200m³ / h, the fish glue in the rotating drum is dried by hot air directional airflow for 0.5-2h, the moisture content of the fish glue is reduced to 50%±5%, and the constant-speed drying is entered;

[0046] Constant-speed drying control, the first rotating speed of the rotating drum is controlled to be 16-18r / min and the second rotating speed of the screw pusher is controlled to be 9-10r / min, the hot air temperature is adjusted to be 55-60℃, the hot air volume is adjusted to be 900-1000m³ / h, the fish glue in the rotating drum is dried by hot air directional airflow for 0.5-3h, the moisture content of the fish glue is reduced to 30%±5%, and the speed-reducing drying is entered;

[0047] Speed-reducing drying control, the first rotating speed of the rotating drum is controlled to be 15-16r / min and the second rotating speed of the pusher is controlled to be 8-9r / min, the hot air temperature is adjusted to be 50-55℃, the hot air volume is adjusted to be 800-900m³ / h, the fish glue in the rotating drum is dried by hot air directional airflow for 0.5-3h, the moisture content of the fish glue is reduced to 18%±5%, and the dehydration is completed.

[0048] The extended scheme accurately adjusts the rotating speed of the rotating drum and the screw pusher, the hot air temperature and the air volume according to the characteristics of fish glue in different drying stages, effectively solving the problems of uneven drying, nutrient loss and high energy consumption that are prone to occur in traditional drying. Compared with traditional single-temperature drying, the method improves the collagen retention rate of fish glue, improves the drying efficiency, and realizes efficient, energy-saving and high-quality fish glue dehydration production.

[0049] As an extension of the above scheme, the soaking pool comprises a first-stage soaking tank, a plurality of middle-stage soaking tanks and a last-stage soaking tank, the plurality of soaking tanks are arranged in a downward inclined arrangement with an inclination angle of 3-15°, and the soaking tanks are connected by inclined pipelines to form gradient soaking, the inclined pipelines are provided with control valves and guide plates, and each stage of soaking tank is provided with a water circulation filtering device;

[0050] The soaking liquid of the first-stage soaking tank contains 10% cooking wine, 3% ginger slices and 0.2% citric acid;

[0051] The soaking liquid of the middle-stage soaking tank contains 5%-7% cooking wine, 2%-2.5% ginger slices and 0.1%-0.15% citric acid;

[0052] The soaking liquid of the last-stage soaking tank contains 5% cooking wine, 2% ginger slices and 0.1% citric acid, and the proportion of water is appropriately increased.

[0053] In the extended scheme, the concentration of the soaking liquid of the first-stage soaking tank is relatively high, so that a large amount of impurities and fishy substances on the surface of the fish glue can be quickly removed when the fish glue enters the soaking process, the concentration of the soaking liquid of the intermediate-stage soaking tanks is gradually reduced, reducing the concentration of the soaking liquid can continuously remove the fishy smell inside the fish glue, avoid over-soaking to cause the fish glue to become soft and nutrients to be lost, and reduce the residue of the soaking liquid components on the surface of the fish glue, and the soaking liquid of the last-stage soaking tank is mainly used for nourishing the fish glue to make the fish glue taste better and reduce the residue of strong volatile components, thereby reducing the burden of the subsequent cleaning process.

[0061] Reference Figure 1 , the following will give some embodiments of a kind of instant flower glue dehydration separation equipment and processing method.

[0062] As Figure 1 shown, in some embodiments, a kind of instant flower glue dehydration separation equipment, comprising:

[0063] Rotary drum 100, cylindrical metal shell, inner wall smooth, two ends are respectively provided with inlet 110 and outlet 120;

[0064] Spiral material feeder 200, including spiral shaft 210 and spiral blade 220 arranged on spiral shaft 210, the spiral material feeder 200 is installed in the rotary drum 100, the spiral shaft 210 of the spiral material feeder 200 is coaxially arranged with the main shaft 130 of the rotary drum 100, the spiral blade 220 has a gap with the inner wall of the rotary drum 100, and the gap is 0.5-2cm;

[0065] First motor 300 is connected with the main shaft 130 of the rotary drum 100 through rigid coupling;

[0066] Second motor 400 is connected with the transmission shaft of the spiral material feeder 200 through differential mechanism 500, for adjusting the speed difference and the forward and reverse rotation between the spiral material feeder 200 and the rotary drum 100;

[0067] Torque sensor 600 is installed on the transmission shaft of the spiral material feeder 200, and the torque change of the spiral material feeder 200 during operation is monitored in real time;

[0068] The hot air circulating device 700 has a first hot air pipe 710 and a second hot air pipe 720, which are respectively connected to the two ends of the rotating drum 100, and form a hot air directional airflow between the rotating drum 100 and the hot air circulating device 700. The first hot air pipe 710 and the second hot air pipe 720 are respectively provided with a temperature sensor 730.

[0069] Compared with the traditional one, the dewatering and separating device of the embodiment adjusts the speed difference and the forward and reverse rotation between the screw pusher and the rotating drum through the second motor and the differential, so that the rotating drum and the screw pusher realize forward and reverse rotation switching, i.e. positive and negative differential ratio switching, the rubber in the rotating drum automatically reciprocates, the uneven residence time caused by one-way conveying is avoided, and the drying uniformity is improved.

[0070] In the embodiment, the rotating drum and the screw pusher are constructed by adopting a differential to build a double tumbling mechanism, the first motor is connected to the main shaft of the rotating drum through a rigid coupling, the rubber in the rotating drum is tumbled, the second motor is connected to the transmission shaft of the screw pusher through a differential to rotate at a speed lower than that of the rotating drum, the rubber is pushed and tumbled, a planetary gear differential is adopted to adjust the speed ratio between the rotating drum and the screw pusher, to ensure the relative movement of the screw pusher and the rotating drum, to avoid extrusion, to promote hot air penetration, and to reduce rubber damage.

[0071] The torque sensor of the embodiment monitors the pushing resistance (reflecting the amount of rubber and the change of moisture content) in real time, adjusts the output of the second motor, and ensures the stability of the differential ratio. When the moisture content of the rubber is high and the viscosity is large, the torque increases, the speed of the second motor is increased, and the screw pusher is prevented from stopping due to resistance. Compared with the traditional independent control which needs to manually preset multiple groups of speed parameters and cannot respond to real-time load changes, the rotating drum may be idling, the screw pusher may be stuck or the rubber may be damaged. According to the dynamic adjustment of the speed of the rotating drum and the screw pusher according to the moisture content of the rubber, the dewatering uniformity is effectively improved.

[0072] The skilled in the art can understand that the inlet and outlet are provided with gates, which are opened during feeding or discharging and closed during dehydration operation. In the present embodiment, the gates of the inlet or outlet are divided into two semicircular or semicone door bodies, which form a complete gate and are arranged at the inlet or outlet. The two semicircular or semicone gates can be opened separately or simultaneously. One door body can be opened for feeding, and two door bodies can be opened simultaneously for discharging. The edge of the door body at the outlet extends from the end to the middle direction, and extends at least over the narrow transition joint of the spiral blade (the spiral blade approaches the end with a reduced outer diameter, and the position where the middle large outer diameter section and the end reduced outer diameter section are connected is the narrow transition joint of the spiral blade), so that the two opened door bodies can push all the rubber out of the drum through the spiral blade during discharging. The structure of the gate and the means for opening and closing can be realized by using the existing technology.

[0073] In some embodiments, the differential 500 is a planetary gear differential, which includes a sun gear, a planet gear, a ring gear and a planet carrier. The planet gear is located between the sun gear and the ring gear and is connected with the planet carrier. It should be noted that the principle and implementation of differential control of the planetary gear differential are realized by using the means of the existing technology, and therefore will not be described in detail here.

[0074] The first motor 300 is in driving connection with the sun gear, the second motor 400 inputs power through the ring gear, and the planet carrier is in driving connection with the spiral pusher 200. Through the driving connection of the planetary gear differential, the drum and the spiral pusher, the first motor drives the sun gear, the second motor drives the ring gear, and the planet carrier outputs to the spiral pusher, forming a differential transmission chain with double inputs and single output. When the second motor rotates in reverse, a negative differential ratio is output (the spiral pusher and the drum rotate in opposite directions), and the bidirectional movement of the spiral pusher is realized.

[0075] In some embodiments, the inlet 110 and the outlet 120 of the drum 100 are respectively provided with infrared sensors 140 for real-time monitoring of the position of the rubber during the dehydration stage.

[0076] When the infrared sensor 140 at the outlet 120 detects the rubber, the rotation direction between the spiral pusher 200 and the drum 100 is switched by the second motor 400, so that the drum 100 and the spiral pusher 200 rotate in opposite directions, the differential ratio is switched to a negative value, and the reverse pushing is started.

[0077] When the infrared sensor 140 at the inlet 110 detects the rubber, the rotation direction between the spiral pusher 200 and the drum 100 is switched by the second motor 400, so that the drum 100 and the spiral pusher 200 rotate in the same direction, the differential ratio is switched to a positive value, the forward pushing is restored, and the closed loop reciprocation is formed.

[0078] For example, when the first motor drives the sun gear to rotate at a first rotational speed N1, the second motor drives the ring gear to rotate at a second rotational speed N2 in the same direction, at which time the rotational speed N3 of the carrier (screw pusher) is (N1+N2) / 2, and the rotational speed difference between the two is N1-N3=(N1-N2) / 2, forming a forward pushing force. When the screw pusher needs to be reversed, the second motor drives the ring gear to rotate in the opposite direction at a rotational speed of -N4, at which time the rotational speed N3' of the carrier is (N1-N4) / 2, and when N1 is less than N4, N3' can be negative, and the screw pusher can be reversed to realize the reciprocating pushing of the rubber. This explanation is to explain that the screw pusher can realize forward and reverse rotation through the differential, and those skilled in the art can also obtain other ways to realize the forward and reverse rotation of the screw pusher according to the existing technology and the conventional application of the differential. The present embodiment does not make any form of limitation on this. In some specific embodiments, the second motor can automatically adjust the rotational speed of the ring gear when the reverse pushing resistance is too large, so as to avoid overload. At the same time, an overload protection mechanism is provided, which cuts off the power of the second motor when the torque exceeds a specified threshold, so as to prevent damage to the equipment.

[0079] In the present embodiment, the infrared sensor is used to monitor the position of the rubber at the inlet and outlet of the rotating drum, so as to trigger the reverse pushing in advance and avoid the accumulation of rubber at the end of the rotating drum and the sudden increase of the resistance of the screw pusher. Compared with the passive response of the torque sensor, the overload impact can be reduced, and the traditional mechanical limit switch needs to be triggered by the contact of the rubber, which is easy to cause the accumulation of the rubber at the end to be too thick.

[0080] In some embodiments, the hot air circulation device 700 comprises:

[0081] A hot air generator is configured to provide hot air at a temperature of 40-65°C.

[0082] A circulating fan is configured to blow the hot air through the first hot air pipeline 710 to one end of the rotating drum 100. The hot air flows through the rubber being turned over and removes the moisture from the surface of the rubber. The hot air flows out from the other end of the rotating drum 100 and returns to the hot air circulation device through the second hot air pipeline 720, forming a directional air flow of hot air. The second hot air pipeline 720 is connected to the hot air circulation device, and a moisture absorption filter layer is arranged at the connection position of the second hot air pipeline 720 and the hot air circulation device. The moisture absorption filter layer is realized by using the existing moisture absorption and / or filtering structure.

[0083] In some specific embodiments, a pressure relief channel and an air pressure sensor are further arranged on the hot air flow path of the hot air circulation device. Specifically, the pressure relief channel and the air pressure sensor can be arranged on the second hot air pipeline. When the air flow pressure is too large, the pressure relief channel is used to maintain the air pressure balance of the hot air circulation device.

[0084] The fish glue of the embodiment reciprocates in the rotating drum and contacts hot air multiple times, so that the moisture content deviation is reduced, the product quality consistency is greatly improved, and at the same time, 40-65℃ hot air is introduced into the rotating drum, so that the hot air is uniformly distributed and penetrates the flipped fish glue, effectively shortens the drying time, improves the production efficiency, and the moisture absorption filter layer is used to absorb the moisture brought out by the second hot air pipeline, so as to ensure the drying of the recycled hot air.

[0085] In some embodiments, the temperature sensor 730 includes a first temperature sensor arranged in the first hot air pipeline 710 and a second temperature sensor arranged in the second hot air pipeline 720, for acquiring the first hot air temperature and the second hot air temperature at the two ends of the rotating drum 100.

[0086] When the temperature difference between the first hot air temperature and the second hot air temperature is greater than a preset temperature difference threshold, the hot air generator is controlled to increase the power to increase the hot air temperature and / or the circulating fan is controlled to increase the hot air volume.

[0087] The embodiment controls the hot air temperature and the hot air volume based on the temperature difference, solves the problem of uneven temperature distribution in traditional hot air drying, and in the traditional equipment, the hot air enters from one end of the rotating drum, due to factors such as material blockage and airflow attenuation, resulting in high temperature at the inlet end (up to 70℃) and low temperature at the outlet end (as low as 40℃), the temperature difference exceeds 20℃, causing uneven drying of the material. The embodiment automatically controls the hot air generator to increase the power to increase the hot air temperature and / or controls the circulating fan to increase the hot air volume, thereby reducing the moisture content deviation of the fish glue.

[0088] In some embodiments, a processing method of instant fish glue includes the following steps:

[0089] Step one: pretreat the dried cylindrical fish glue, which includes thawing, rinsing the surface and inner wall, and cutting into blocks or sheets;

[0090] Place the dried cylindrical fish glue in a 0-4℃ low-temperature flowing water environment for thawing, or thaw it in a 4℃ or lower refrigerator, and control the thawing time to be 8-12 hours according to the thickness of the fish glue. After thawing, rinse the surface of the fish glue with flowing water, and brush it gently with a soft brush to remove dust, residual salt and mucus;

[0091] The pipe insertion inner wall flushing technology is used to insert the water pipe into the tubular caoutchouc, and the inner wall is flushed by high pressure water flow of 0.2-0.5 MPa to completely remove blood water, grease and attached impurities. If necessary, 0.5% concentration of food grade baking soda solution can be added to assist in cleaning, and then medical forceps or cotton swab is used to clean the residual fish oil in the wrinkles. The traditional process for cleaning the inner wall of the tubular caoutchouc often uses manual flushing or simple soaking, which is difficult to completely remove the internal blood water and grease. In this embodiment, the pipe insertion inner wall flushing technology is used to flush the inner wall with high pressure water flow of 0.2-0.5 MPa, and baking soda solution can also be added to assist in cleaning.

[0092] According to the product specification requirements, the caoutchouc is cut into blocks of 3-5 cm or longitudinally cut into slices, ensuring that the cut is neat and avoiding the generation of debris.

[0093] Step two: the cut caoutchouc is sent into the soaking pool formed by multiple stages in series, the water is purified in real time through the water circulation filtration pipeline, the water temperature is maintained at 20-25°C, after soaking is completed, the caoutchouc is lifted from the soaking pool by the mesh belt conveyor, and the caoutchouc is flushed by the high pressure spray head during the transmission process to remove the residual soaking liquid on the surface. In this step, the water circulation filtration pipeline is connected with the water circulation filtration device (activated carbon + precision filter screen), which is realized by existing technical means. In some specific embodiments: the circulation flow control is 1-2 times / hour, the caoutchouc is soaked in the soaking pool step by step, the total time is 8-12 hours, the soaking liquid is automatically replaced 1-2 times in the middle, the water circulation filtration device can purify the soaking liquid in real time, prolong the service life of the soaking liquid, reduce resource waste, reduce production cost, and at the same time ensure the hygiene of the soaking environment, laying a solid foundation for the production of high-quality instant caoutchouc.

[0094] Step three: the caoutchouc enters the dehydration separation equipment of the instant caoutchouc in the above embodiment, and is dehydrated at a hot air temperature of 40-65°C and a hot air volume of 800-1200 m³ / h. The dehydrated caoutchouc falls on the vibrating dewatering conveyor, and the surface free water is removed by vibration with an amplitude of 5-10 mm. The infrared moisture detector at the end of the vibrating dewatering conveyor monitors in real time to ensure that the moisture content of the caoutchouc is ≤30%.

[0095] Step four: the vibrating dewatering conveyor sends the caoutchouc into the paddle type mixing conveyor, and a quantitative pump injects preheated seasoning liquid at 60-70°C. The paddle stirs at a speed of 30-50 rpm to evenly coat the caoutchouc with the seasoning liquid. Traditional seasoning is usually manually stirred, which is not uniform and easily causes nutrient loss. The paddle type mixing conveyor is used, the paddle is covered with silica gel, and low-speed stirring effectively improves the uniformity of the mixing of the seasoning liquid and the caoutchouc.

[0096] Step five: the mixed fish maw is sent into a continuous sterilization kettle through a sterile pipeline (pipe diameter DN50-DN80, conveying pressure 0.1-0.2 MPa, flow rate 1-2 m / s) to be sterilized at 121°C for 15 min, and then enters a counter-pressure cooling tunnel, in which the water temperature is gradiently reduced from 80°C to 40°C, and the center temperature of the fish maw is reduced to 40°C within 8 min;

[0097] Step six: the sterilized fish maw falls into a filling part, and then is filled, packaged, detected and stored; the sterilized fish maw falls into a filling rotary table through a pneumatic turnover device, a negative pressure adsorption type feeding machine (suction force 0.05-0.08 MPa) precisely puts the fish maw into a prefabricated packaging bag / tank, the filling process is carried out under a hundred-level cleanliness laminar flow cover, and after the filling is completed, a vacuum packaging machine is used for packaging, and the vacuum degree is ≤-0.08 MPa.

[0100] In some embodiments, in step three:

[0101] In the start-up phase of the isinglass entering the dehydration separation device, the first motor starts the rotation of the rotating drum at a set first rotating speed, and the second motor drives the screw pusher at a second rotating speed through the differential mechanism, and the differential ratio of the first rotating speed and the second rotating speed is 1.2-2.5:1.

[0102] In the dehydration phase, the second motor adjusts the second rotating speed in real time according to the torque feedback of the torque sensor, maintains the differential ratio set in the current process, and ensures that when the first rotating speed of the rotating drum decreases due to the increase of the load, the differential mechanism synchronously reduces the second rotating speed of the screw pusher, so as to avoid the accumulation of isinglass due to the mismatch of the speeds.

[0103] The embodiment effectively solves the problems of material accumulation, equipment overload and uneven drying in the dehydration process of isinglass through dynamic adjustment of torque feedback. The torque sensor monitors the load change in real time, and the second motor dynamically adjusts the rotating speed of the screw pusher to ensure that the differential ratio is constant. Even if the rotating speed of the rotating drum decreases due to the viscosity or accumulation of isinglass, the screw pusher can also reduce the speed synchronously to maintain the speed matching of the two, prevent the material from accumulating and blocking, improve the running stability and production efficiency of the equipment, and at the same time, ensure the uniform transportation and heating of isinglass in the rotating drum, increase the drying uniformity, and effectively improve the product quality and production efficiency.

[0104] In some embodiments, the torque sensor collects the real-time torque value of the transmission shaft of the screw pusher at a frequency of 100 Hz, and transmits it to the controller for processing. The controller sets a normal working torque threshold value in advance, and the controller performs the following processing steps:

[0105] When the real-time torque value exceeds the upper threshold value, it indicates that the pushing resistance increases due to the viscosity or accumulation of isinglass, and the controller sends an acceleration instruction to the second motor;

[0106] When the real-time torque value is lower than the lower threshold value, it indicates that the water content of isinglass has decreased to a lower level or the feeding amount is too small or the material in the rotating drum is sparse, and the drying is easy to push, so the pushing resistance decreases and the torque decreases. The controller sends a speed reduction instruction to the second motor to save energy on the premise of ensuring the dehydration effect, avoid over-drying or idling, and realize dynamic adjustment.

[0107] The embodiment can accurately cope with the complex working conditions in the dehydration process of isinglass through 100Hz high-frequency sampling and intelligent threshold judgment mechanism, and effectively solve the problems of material blocking, energy waste and unstable quality existing in traditional equipment. The embodiment can adapt to the water content difference of different batches of isinglass, realize real-time optimization of production parameters, and improve the drying uniformity and product qualification rate.

[0108] When the torque exceeds the upper threshold, the controller responds quickly and drives the second motor to accelerate, which can enhance the pushing capacity of the screw pusher in a short time, reduce the risk of equipment downtime caused by material accumulation, and significantly improve production continuity; when the torque is below the lower threshold, the deceleration instruction is automatically triggered to avoid motor idling and material over-drying, and compared with the traditional constant speed mode, energy consumption is reduced.

[0109] In some embodiments, the processing method comprises a hot air temperature segmented control step:

[0110] Pre-drying control, when the first rotational speed of the drum is 18-20 r / min and the second rotational speed of the screw pusher is 10-11 r / min, the hot air temperature is controlled to be 60-65°C, the hot air volume is 1000-1200 m³ / h, the hot air drying of the rubber sheet in the drum is performed by hot air directional airflow for 0.5-2 h, the moisture content of the rubber sheet is reduced to 50%±5%, and the constant speed drying is entered;

[0111] Constant speed drying control, the first rotational speed of the drum is controlled to be 16-18 r / min and the second rotational speed of the pusher is controlled to be 9-10 r / min, the hot air temperature is adjusted to be 55-60°C, the hot air volume is adjusted to be 900-1000 m³ / h, the hot air drying of the rubber sheet in the drum is performed by hot air directional airflow for 0.5-3 h, the moisture content of the rubber sheet is reduced to 30%±5%, and the speed reduction drying is entered;

[0112] Speed reduction drying control, the first rotational speed of the drum is controlled to be 15-16 r / min and the second rotational speed of the pusher is controlled to be 8-9 r / min, the hot air temperature is adjusted to be 50-55°C, the hot air volume is adjusted to be 800-900 m³ / h, the hot air drying of the rubber sheet in the drum is performed by hot air directional airflow for 0.5-3 h, the moisture content of the rubber sheet is reduced to 18%±5%, and the dehydration is completed.

[0113] The embodiment is aimed at the characteristics of dried fish skin at different drying stages. The rotation speed of the drum and the screw pusher, the hot air temperature and the air volume are accurately controlled to effectively solve the problems of uneven drying, nutrient loss, high energy consumption and other problems in traditional drying. In the pre-drying stage, the higher hot air temperature (60-65℃) and the fast fish skin turning speed (drum 18-20r / min, pusher 10-11r / min) can quickly evaporate the surface moisture of the fish skin in 0.5-2h, and the moisture content is reduced to 50%±5%, laying a foundation for subsequent drying. In the constant-speed drying stage, the hot air temperature is reduced to 55-60℃ and the material movement speed is slowed down, which can ensure continuous evaporation of water while avoiding denaturation of collagen due to high temperature, and the moisture content is stably reduced to 30%±5%. In the low-speed drying stage, low temperature (50-55℃), low air volume (800-900m³ / h) and low speed operation are adopted to slowly discharge the internal moisture of the fish skin, and the final moisture content is accurately controlled at 18%±5%, which not only ensures the dehydration effect, but also maximizes the retention of fish skin nutrients and taste. Compared with traditional single-temperature drying, this method improves the retention rate of collagen in dried fish skin, improves the drying efficiency, and realizes efficient, energy-saving and high-quality fish skin dehydration production.

[0114] In some embodiments, the soaking pool comprises a first-stage soaking tank, a plurality of middle-stage soaking tanks and a final-stage soaking tank, the plurality of soaking tanks are arranged in a downward inclined arrangement at an inclination angle of 3-15°, and the soaking tanks are connected by inclined pipelines to form gradient soaking, the inclined pipelines are provided with control valves and guide plates, and each stage of soaking tank is provided with a water circulation filtering device;

[0115] The cut dried fish skin is sent into the soaking pool for soaking by the soaking liquid, the soaking liquid comprises the following components in percentage by weight: 5-10% cooking wine, 2-3% ginger slices, 0.1-0.2% citric acid, and the balance is water, wherein:

[0116] In the soaking liquid of the first-stage soaking tank, the content of cooking wine is 10%, the proportion of ginger slices is 3%, and the content of citric acid is 0.2%;

[0117] The concentration of the soaking liquid in the middle-stage soaking tank gradually decreases, the content of cooking wine is controlled at 5%-7%, the proportion of ginger slices is 2%-2.5%, and the content of citric acid is 0.1%-0.15%;

[0118] In the soaking liquid of the final-stage soaking tank, the content of cooking wine is 5%, the proportion of ginger slices is 2%, the content of citric acid is 0.1%, and the proportion of water is appropriately increased.

[0119] In this embodiment, the first soaking tank mainly undertakes the task of decontamination. After cutting, the surface and incision of the rubber sheet will remain some processing debris, a small amount of blood water and impurities that have not been completely removed in the previous treatment. The soaking liquid in the first soaking tank exerts strong decontamination effect under the synergistic action of multiple components. As the base solvent, the alcohol component in cooking wine can dissolve part of the oil and grease impurities, and its volatility helps to preliminarily disperse the fishy smell; ginger slices contain components such as gingerol, which can not only assist in deodorization, but also have an inhibitory effect on some microorganisms; citric acid can adjust the pH of the soaking liquid, promote the chemical reaction of some insoluble dirt, and convert it into a soluble state, which is convenient for cleaning and removal. In this stage, the soaking liquid is continuously purified by the water circulation and filtration device. Activated carbon can adsorb pigments, odor molecules and small organic impurities in the soaking liquid, and precision filter screen can intercept particulate impurities, maintain the cleanliness of the soaking liquid and ensure the persistence of the decontamination effect.

[0120] The intermediate several soaking tanks mainly focus on the deep deodorization and flavor improvement of the rubber sheet. As the rubber sheet enters the first soaking tank, the residual fishy smell is further removed. At this time, the cooking wine and ginger slices in the soaking liquid continue to play a deodorizing role, and the presence of citric acid helps the rubber sheet to maintain certain texture stability during the soaking process, preventing excessive softening. Due to the long soaking time and the gradual loosening of the internal structure of the rubber sheet during the soaking process, the soaking liquid can penetrate deeper into the tissue of the rubber sheet and replace the fishy components therein. And by controlling the circulation flow rate at 1-2 times / hour, the soaking liquid remains active and continuously exchanges with the fishy components in the rubber sheet, further improving the deodorization effect.

[0121] The last soaking tank focuses on the quality fine-tuning of the rubber sheet and the removal of residual soaking liquid. After the treatment of the previous soaking tanks, the fishy smell of the rubber sheet has been greatly reduced. In the last soaking tank, the proportion of the components of the soaking liquid can be adjusted appropriately to reduce the content of strong volatile components such as cooking wine, so as to avoid excessive residual odor. At this time, the soaking liquid plays a more role in nourishing the rubber sheet, making the rubber sheet more soft and tender in taste. At the same time, the water circulation and filtration device continues to work to ensure the purity of the soaking liquid and prevent secondary pollution.
