Description

Technical Field

[0001] This application relates to the field of jam processing, and in particular to a jam concentration processing device. Background Technology

[0002] Jam is a product obtained by processing fruit through a series of processes using equipment.

[0003] For example, patent application number 202222863878.0 discloses a jam concentration processing device, but it still has the following shortcomings in actual use:

[0004] The aforementioned device consists of core components such as the main body of the equipment, the equipment mounting frame, and a dual-shaft motor. It achieves automatic opening and closing of the sealing cover through gear transmission and a reciprocating screw mechanism, effectively preventing splashing during stirring. However, in actual use, the heating tube inside the stirring rod is close to the surface, which can easily lead to uneven heating of the jam. Furthermore, the stirring rod cannot break the laminar flow boundary layer at the bottom and side walls of the equipment, causing the jam in the stagnant area to be heated for too long, increasing the risk of scorching. At the same time, the equipment lacks a wall scraping function, making it difficult to clean the jam residue on the barrel wall, affecting the performance of the equipment and the quality of the jam. The heat is also difficult to reuse, which can easily lead to waste. Utility Model Content

[0005] To improve the problem of uneven heating of jam and local overheating leading to caramelization, this application provides a jam concentration and processing device.

[0006] The jam concentration and processing equipment provided in this application adopts the following technical solution:

[0007] A jam concentration processing device includes a storage tank and a sealing cover fixed to the top of the storage tank. A stirring mechanism for stirring jam is rotatably mounted in the middle of the sealing cover and located inside the storage tank. A motor for providing driving force to the stirring mechanism is fixed to the top of the stirring mechanism. A base is fixed to the bottom of the storage tank. A hot air circulation channel penetrating the inside and outside of the storage tank is opened in the middle of the base. A Y-shaped discharge pipe for discharging processed jam is fixedly installed through the bottom of the base. The stirring mechanism includes a reciprocating screw rotatably mounted in the middle of the sealing cover and fixed to the output end at its top, and a screw nut with threads on the surface of the reciprocating screw. Multiple stirring blades are fixed to the outer circumference of the screw nut. A connecting block is fixed to the end of the stirring blade away from the screw nut. A scraper that slides inside the storage tank is fixed to the end of the connecting block away from the stirring blade. Scrapers are fixed to both ends of the scraper.

[0008] By adopting the above technical solution, the storage tank, sealing cover and base constitute the main body of the equipment. The motor on the sealing cover drives the stirring mechanism to stir the jam in the storage tank. The hot air circulation channel of the base can recover gas. The Y-shaped discharge pipe is used to discharge the processed jam. In the stirring mechanism, the reciprocating screw drives the screw nut to move back and forth. The stirring blade on the screw nut stirs the jam. The scraper and scraper are used to scrape off the jam adhering to the inner wall of the storage tank.

[0009] Preferably, a heat-conducting plate is fixedly provided on the inner wall of the storage barrel, and an electric heating wire is spirally laid between the storage barrel and the heat-conducting plate, forming a heating layer with the storage barrel, the heat-conducting plate and the electric heating wire.

[0010] By adopting the above technical solution, the heat-conducting plate on the inner wall of the storage barrel works in conjunction with the barrel body, and the heating wire is energized to generate heat. The three together form a heating layer, which realizes uniform heating of the jam in the storage barrel.

[0011] Preferably, the inner wall of the heat-conducting plate is provided with a threaded groove that matches the helix angle, number of turns, and stroke of the nut on the surface of the reciprocating lead screw.

[0012] By adopting the above technical solution, the threaded groove opened on the inner wall of the heat-conducting plate has the same helix angle and number of turns as the thread on the surface of the reciprocating screw, and is adapted to the stroke of the screw nut on the reciprocating screw, so as to ensure that the screw nut drives the stirring assembly to smoothly perform reciprocating spiral motion along the inner wall of the heat-conducting plate, thus ensuring the stirring effect.

[0013] Preferably, a slider that slides along the inside of the threaded groove is fixed in the middle of the side of the scraper away from the connecting block.

[0014] By adopting the above technical solution, the slider slides along the threaded groove inside the inner wall of the heat-conducting plate, providing guidance for the reciprocating spiral motion of the scraper in the storage bucket, thereby improving the scraping effect of the scraper on the inner wall of the storage bucket.

[0015] Preferably, the reciprocating lead screw has a hollow channel for transmitting hot air inside, and a rectangular hole communicating with the hollow channel is formed on the outer circumference of the end of the reciprocating lead screw located above the sealing cover.

[0016] By adopting the above technical solution, the hollow channel opened inside the reciprocating screw creates a path for heat transmission. The rectangular hole is connected to the hollow channel, allowing hot air to enter the hollow channel through the rectangular hole, providing an auxiliary heat source for jam heating and ensuring the temperature requirements during jam processing.

[0017] Preferably, dynamic sealing rings are fixed at both ends of the nut, and a stop block is fixed at the opposite end of each of the two dynamic sealing rings. A scraper block that slides along the thread of the reciprocating screw is fixed on the side of the stop block near the reciprocating screw.

[0018] By adopting the above technical solution, the dynamic sealing rings at both ends of the screw nut, together with the stop block and the scraper block that slides along the reciprocating screw thread on the stop block, play the role of sealing and scraping off the jam on the surface of the reciprocating screw.

[0019] Preferably, the outer wall of one end of the reciprocating screw located outside the sealing cover is movably fitted with a sealing cover that communicates with the hollow channel, and a dynamic sealing ring is fixedly provided at the top of the sealing cover.

[0020] By adopting the above technical solution, the combination of the sealing cover and the dynamic sealing ring achieves a stable effect on the transport of hot air in the hollow channel inside the reciprocating screw.

[0021] Preferably, an air pump for drawing hot air from the heating layer into the hollow channel is fixedly provided on one side of the top of the sealing cover. The air pump has an air extraction pipe fixedly connected to the top of the sealing cover, and the air pump has an air delivery pipe fixedly connected to the outer wall of the sealing cover.

[0022] By adopting the above technical solution, the air pump draws hot air from the heating layer through the air extraction pipe and sends it into the hollow channel connected inside the sealing cover through the air delivery pipe.

[0023] Preferably, the outer wall of the base has a through hole that communicates with the hot air circulation channel and the heating layer, and the outer wall of the base is fixed with an air filter screen at the through hole. An exhaust pipe is fixedly installed in the middle of the bottom of the storage tank.

[0024] By adopting the above technical solution, the through hole on the outer wall of the base connects the hot air circulation channel and the heating layer, which facilitates the recovery and reuse of hot air. The filter screen on the base is used to filter the air, and the exhaust pipe at the bottom of the storage tank is used to discharge hot air and condensate.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. This application uses a motor to drive a reciprocating screw to rotate. As the slider on the side wall of the scraper slides in the threaded groove, the screw nut drives the stirring blade and scraper to reciprocate spirally along the axis of the reciprocating screw. This causes the scrapers at both ends of the scraper to repeatedly scrape the inner wall of the heat-conducting plate, thereby breaking the laminar flow boundary layer at the bottom and side wall of the equipment. At the same time, it scrapes off the jam adhering to the inner wall of the heat-conducting plate, preventing the jam in the stagnant area from being heated for too long and causing it to scorch, thus improving the quality of jam processing and the ease of cleaning the equipment.

[0027] 2. Hot air is drawn from the heating layer by an air pump and transmitted through an air supply pipe to the hollow channel inside the reciprocating screw. This allows the hot air to heat the jam evenly on both the inner wall of the heat-conducting plate and the outer wall of the reciprocating screw. Some of the hot air is mixed with filtered fresh air through the hot air circulation channel and then circulated back to the heating layer for reuse. This achieves efficient heat utilization, reduces energy waste, and lowers processing costs.

[0028] 3. The scrapers on both sides of the dynamic sealing ring slide along the threads of the reciprocating screw to scrape off the jam residue in the threads, preventing the jam from burning due to local overheating in the reciprocating screw area. At the same time, it removes stubborn residues during cleaning, improving the stability of equipment operation and cleaning effect. Attached Figure Description

[0044] The following is in conjunction with the appendix Figure 1 - Figure 10 This application will be described in further detail.

[0045] This application discloses a jam concentration processing device.

[0046] Reference Figure 1 - Figure 3 , Figure 8 - Figure 10 A jam concentration processing device includes a storage tank 1 and a sealing cap 4 fixed to the top of the storage tank 1. The storage tank 1 provides storage space for the jam. The sealing cap 4 is used to seal the top of the storage tank 1. A circular hole is opened in the middle of the sealing cap 4. An exhaust port 17 is opened on one side of the top of the sealing cap 4. An inlet 27 is opened on the side of the top of the sealing cap 4 opposite to the exhaust port 17. The inlet 27 is used to transport the jam into the interior of the storage tank 1 or to introduce a cleaning solution into the interior of the storage tank 1 after the jam processing is completed. A sealing plug 26 is movably installed inside the inlet 27. The feed inlet 27 is symmetrically distributed on both sides of the circular hole 1 along the diameter direction of the sealing cover 4, and the distance between them is equal. A heat-conducting plate 28 is fixedly provided on the inner wall of the storage barrel 1. The heat-conducting plate 28 is used to conduct heat. The heat-conducting plate 28 is fixedly set on the inner wall of the storage barrel 1. The heating wire 19 is spirally wound along the outer wall of the storage barrel 1 and connected to the power supply through a temperature control relay. The heat-conducting plate 28 transfers the heat generated by the heating wire 19 to the inside of the storage barrel 1 through heat conduction. The outer wall of the storage barrel 1, the inner wall of the heat-conducting plate 28 and the heating wire 19 together constitute a heating layer for heating the jam inside the storage barrel 1.

[0047] Before use, place the device on the floor of a small to medium-sized processing workshop, fix the storage tank 1 to the top of the base 3, connect the hot air circulation channel 24 in the middle of the base 3 with the inside of the storage tank 1, connect the air inlet hole 25 with the heating layer, and install the filter screen 11 at the hole 25. Install the Y-shaped discharge pipe 5 at the bottom of the base 3 and install the valve 12 at the lower end of the Y-shaped discharge pipe 5. Fix the heat-conducting plate 28 of the heating layer to the inner wall of the storage tank 1, and spirally lay the heating wire 19 between the storage tank 1 and the heat-conducting plate 28 to form a spiral heating layer. Fix the sealing cover 4 to the top of the storage tank 1. Install the stirring mechanism 2 of the stirring device inside the storage tank 1. Fix the motor 6 at the top of the stirring mechanism 2 to the top of the sealing cover 4 through the fixing bracket 8 of the outer ring. Fix the air extraction pipe 9 to the air extraction hole 17 of the top sealing cover 4, and fix the air supply pipe 10 to the sealing cover 14.

[0048] A stirring mechanism 2 is rotatably mounted in the middle of the sealing cap 4. The stirring mechanism 2 is located inside the storage tank 1 and is used to stir the jam. A motor 6 is fixed to the top of the stirring mechanism 2, which provides driving force to the stirring mechanism 2. Multiple fixed brackets 8 are fixed around the bottom of the motor 6, and the bottom of the fixed brackets 8 is fixed to the top of the sealing cap 4. A base 3 is fixed to the bottom of the storage tank 1. A hot air circulation channel 24 is opened in the middle of the base 3, which runs through the inside and outside of the storage tank 1. The outer wall of the base 3 is opened with... There is a through hole 25 that communicates with the hot air circulation channel 24 and the heating layer. The through hole 25 is used to introduce air into the heating layer and transfer the recovered hot air. A filter screen 11 is fixed on the outer wall of the base 3 at the through hole 25. The filter screen 11 is used to filter dust in the air and prevent dust from entering the heating layer. A circular hole 21 is opened in the middle of the top of the base 3. The circular hole 21 communicates with the hot air circulation channel 24. An exhaust hole 22 is opened in the middle of the bottom of the base 3. The exhaust hole 22 communicates with the circular hole 21 and the hot air circulation channel 24.

[0049] An exhaust pipe 13 is fixedly installed at the bottom end of the base 3, located at the exhaust hole 22, to discharge some hot air. A pressure relief valve is connected to the end of the exhaust pipe 13 away from the base 3 to balance the air pressure inside the heating layer and the storage tank 1, as well as to discharge condensate from the auxiliary channel. Discharge holes 23 are symmetrically opened on both sides of the circular hole 21 at the top of the base 3. A Y-shaped discharge pipe 5 is fixedly installed at the bottom end of the base 3, located at the discharge hole 23. The Y-shaped discharge pipe 5 includes a main pipe and two branch pipes. The upper end of the main pipe is fixedly connected to the discharge hole 23 at the bottom end of the base 3, and the lower end of the main pipe is the outlet, facilitating rapid filling of the jam. The lower end of the Y-shaped discharge pipe 5 is fixedly equipped with a valve 12, which is used to control the opening and closing of the Y-shaped discharge pipe 5 and the flow rate of the jam inside the Y-shaped discharge pipe 5. Several support columns 20 are fixedly provided on the outer circumference of the bottom end of the base 3, and the top of the support column 20 is fixed to the bottom end of the base 3. An air pump 7 is fixedly provided on one side of the top end of the sealing cover 4. The air pump 7 is used to draw the hot air of the heating layer into the interior of the hollow channel 210. The air inlet of the air pump 7 is fixedly connected to the air extraction pipe 9. The end of the air extraction pipe 9 away from the air pump 7 is fixedly connected to the air extraction hole 17 at the top of the sealing cover 4. The air outlet of the air pump 7 is fixedly connected to the air supply pipe 10.

[0050] In use, the jam is introduced into the storage tank 1 through the feed inlet 27. The motor 6 is started to drive the stirring mechanism 2, causing the jam in the storage tank 1 to flow. The heat is evenly heated by the heat-conducting plate 28 in the heating layer and the spirally laid heating wire 19. The air pump 7 draws hot air from the heating layer through the air extraction pipe 9 from the air extraction hole 17 of the sealing cover 4, and transmits it through the air supply pipe 10 to the reciprocating screw 201 to heat the jam in the storage tank 1 near the reciprocating screw 201. Some of the hot air is circulated through the hot air circulation channel 2 inside the base 3. 4. A small amount of fresh air is mixed with the through hole 25 and re-enters the heating layer for recycling. A small amount of hot air is discharged through the exhaust hole 22 and the exhaust pipe 13, or the exhaust pipe 13 is connected to the jam preheating equipment to preheat part of the jam. Then the power of the heating wire 19 is turned off. The continuous circulation of hot air and fresh air cools the jam. After the jam is concentrated, it is discharged through the Y-shaped discharge pipe 5. The cleaning solution is introduced into the storage tank 1 through the inlet 27. The motor 6 is started to rotate and drive the stirring mechanism 2 to rotate, which drives the cleaning solution to flow to flush the inner wall of the container.

[0051] Reference Figure 6 - Figure 10The stirring mechanism 2 includes a reciprocating lead screw 201 rotatably disposed in the middle of the sealing cover 4 and fixed at its top end to the output end, and a nut 202 threaded onto the surface of the reciprocating lead screw 201. The upper end of the reciprocating lead screw 201 rotatably passes through a circular hole 1, and the end of the reciprocating lead screw 201 away from the sealing cover 4 rotatably passes through a circular hole 21. The threads on the surface of the reciprocating lead screw 201 are formed in the part of the reciprocating lead screw 201 located inside the storage tank 1, for realizing the reciprocating linear motion of the nut 202. Multiple stirring blades 203 are fixed around the outer circumference of the nut 202. The stirring blades 203 rotate with the nut 202 and are used to shear and stir the jam. The mixing blade 203 is fixed with a connecting block 204 at one end away from the mother filament 202. The connecting block 204 is fixed with a scraper 205 at one end away from the mixing blade 203. The scraper 205 is made of food-grade silicone. Flexible scrapers 206 are fixed at both ends of the scraper 205. The scraper 206 forms a dynamic elastic fit with the inner wall of the heat-conducting plate 28. The scraping surface is provided with staggered micro-cleaning protrusions. During the reciprocating spiral motion, the scraper 206 generates high-frequency micro-vibration through the micro-cleaning protrusions to scrape off the jam attached to the inner wall of the heat-conducting plate 28, breaking the laminar flow boundary layer of the side wall and avoiding the jam retention area from being heated for too long, which increases the risk of scorching.

[0052] In use, the motor 6 is started to drive the reciprocating screw 201 to rotate, which in turn drives the screw nut 202 to reciprocate linearly along the axis of the reciprocating screw 201. This causes the stirring blade 203 fixed on the outer wall of the screw nut 202 and the connected connecting block 204 and scraper 205 to rotate synchronously. Because the slider 207 on the side wall of the scraper 205 slides in the threaded groove 18 opened in the inner wall of the heat-conducting plate 28, the stirring blade 203 and the scraper 205 and scraper 206 reciprocate spirally. This causes the scraper 206 to repeatedly scrape the inner wall of the heat-conducting plate 28, thereby scraping off the jam adhering to the inner wall of the heat-conducting plate 28 and preventing local overheating and scorching. After being filtered through the filter screen 11, the hot air enters the heating layer through the through hole 25. The air pump 7 is started to extract the hot air from the heating layer into the sealed cover 14 through the air extraction pipe 9 and the air delivery pipe 10. The hot air enters the hollow channel 210 inside the reciprocating screw 201 through the rectangular hole 209. The jam is heated evenly on the inner wall of the heat-conducting plate 28 and the outer wall of the reciprocating screw 201 at the same time. Some of the hot air in the hollow channel 210 is discharged through the exhaust hole 22 and the exhaust pipe 13. The remaining hot air enters the hot air circulation channel 24 and flows to the through hole 25. It mixes with the fresh air filtered by the filter screen 11 and re-enters the heating layer for secondary use.

[0053] Meanwhile, the dynamic sealing rings 211 at both ends of the screw nut 202 prevent jam from entering the gap between the reciprocating screw 201 and the screw nut 202. The scraper 212 on the side wall of the dynamic sealing ring 211 slides along the thread of the reciprocating screw 201 to scrape off the jam remaining in the thread and prevent overheating and charring. The valve 12 is opened so that the concentrated jam can be discharged through the Y-shaped discharge pipe 5.

[0054] A slider 207 is fixedly mounted in the middle of the side of the scraper 205 away from the connecting block 204. A threaded groove 18 is formed on the inner wall of the heat-conducting plate 28. The rotation angle and number of turns of the threaded groove 18 are consistent with the rotation angle and number of turns of the thread on the surface of the reciprocating screw 201. The shape of the slider 207 is adapted to the threaded groove 18, and the slider 207 slides inside the threaded groove 18, causing the nut 202 to drive the stirring blade 203 and the scraper 205 to reciprocate in a spiral motion as the reciprocating screw 201 rotates. When the slider 207 slides, it removes the jam from the inner wall of the threaded groove 18, facilitating subsequent cleaning. The reciprocating screw 201... There is a hollow channel 210 for transmitting hot air. A rectangular hole 209 is opened on the outer circumference of the end of the reciprocating screw 201 above the sealing cover 4. The rectangular hole 209 is connected to the hollow channel 210. Both ends of the screw nut 202 are fixed with dynamic sealing rings 211. The dynamic sealing rings 211 are lip-shaped sealing rings and are sleeved on the outer wall of the reciprocating screw 201. They are used to achieve dynamic sealing when the screw nut 202 moves back and forth along the reciprocating screw 201 to prevent jam from entering the gap between the reciprocating screw 201 and the screw nut 202.

[0055] When cooling is required, turn off the power of the heating wire 19 to stop heating, adjust the suction power of the air pump 7 to allow fresh air from the outside or cold air discharged from the refrigeration equipment to enter the heating layer through the filter screen 11 and the through hole 25, and continuously circulate through the suction pipe 9, the air supply pipe 10, the sealing cover 14, the reciprocating screw 201, the hot air circulation channel 24, and the Y-shaped discharge pipe 5 to cool the jam inside the device. The condensate generated in this process is discharged through the exhaust hole 22 and the exhaust pipe 13.

[0056] Both dynamic sealing rings 211 have a stop block 208 fixed at opposite ends. A scraper block 212 is fixed on the side of the stop block 208 near the reciprocating lead screw 201. The shape of the scraper block 212 matches the cross-sectional shape of the threaded groove on the surface of the reciprocating lead screw 201. When the nut 202 reciprocates, the scraper block 212 slides along the threaded groove on the surface of the reciprocating lead screw 201, scraping away any residual jam in the threaded groove. This prevents the jam from overheating and causing it to caramelize during jam processing. It also helps to remove jam residue during equipment cleaning. Jam in the threads on the surface of the reciprocating screw 201; a sealing cover 14 is movably fitted on the outer wall of one end of the reciprocating screw 201 located outside the sealing cover 4; the bottom end of the sealing cover 14 is fixed to the middle of the top end of the sealing cover 4; an air supply hole 16 is opened on the outer wall of the sealing cover 14; the air supply hole 16 communicates with the rectangular hole 209; a dynamic sealing ring 15 is fixedly installed on the top end of the sealing cover 14; the end of the air supply pipe 10 away from the air pump 7 is fixedly connected to the air supply hole 16 on the outer wall of the sealing cover 14; and the sealing cover 14 is located in the inner ring of multiple fixed brackets 8.

[0057] When the device needs cleaning, the sealing plug 26 is opened and the cleaning solution is introduced through the feed port 27. The motor 6 is started to drive the reciprocating screw 201 to continuously reciprocate in a spiral motion, which drives the screw nut 202, stirring blade 203, and scraper 205 to move synchronously. The scraper 205, scraper blade 206, and slider 207 scrape off the residual jam on the inner wall of the heat-conducting plate 28 and inside the threaded groove 18, respectively. The reciprocating spiral motion of the stirring blade 203 and scraper 205 stirs the solution to rinse the inner wall of the equipment. At the same time, the scraper block 212 slides along the thread on the surface of the reciprocating screw 201 to remove stubborn residues in the thread. The solution is discharged through the Y-shaped discharge pipe 5.

[0058] The implementation principle of the jam concentration processing equipment in this application embodiment is as follows: During use, jam is injected through the feed inlet 27, the heating wire 19 is powered on, and the air pump 7 is started to draw hot air from the heating layer into the hollow channel 210. The inner wall of the heat-conducting plate 28 and the outer wall of the reciprocating screw 201 cooperate to evenly heat the jam. Some of the hot air is discharged through the exhaust pipe 13, and some of the hot air is returned to the heating layer with the mixed fresh air through the hot air circulation channel 24. The motor 6 is started to drive the reciprocating screw 201 to rotate, which drives the screw nut 202 to reciprocate in a spiral motion, so that the stirring blade 203 and the scraper 205 reciprocate in a spiral motion simultaneously. The slider 207 slides in the threaded groove 18 on the inner wall of the heat-conducting plate 28 to scrape off the jam. At the same time, the stirring blade 203 and the scraper 206 cooperate to stir and clean the bottom of the equipment. The laminar boundary layer on the sidewall is formed, and the scraper 212 slides along the thread of the reciprocating screw 201 to scrape off the jam on the surface of the reciprocating screw 201. The concentrated jam is discharged through the Y-shaped discharge pipe 5. When cooling is required, the power of the heating wire 19 is turned off, and the air pump 7 is adjusted to introduce fresh air or cold air circulation cooling from the through hole 25 and the filter screen 11. The generated condensate is discharged from the exhaust pipe 13. The cleaning solution is injected from the feed port 27, and the motor 6 is started to drive the stirring mechanism 2 to reciprocate spirally, so that the stirring blade 203 and the scraper 205 stir the solution to wash the inner wall of the heat-conducting plate 28. The scraper 206, the slider 207 and the scraper 212 work together to scrape off the jam remaining on the inner wall of the heat-conducting plate 28, the inner wall of the threaded groove 18 and the surface of the reciprocating screw 201. The wastewater is discharged through the Y-shaped discharge pipe 5.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
