Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a negative pressure wolfberry puree pressing and sterilizing device. Background Technique

[0002] Wolfberry puree is processed with wolfberries as raw materials. It is required that the wolfberries must be naturally grown, pure natural, free of agricultural residues, and contain no additives, preservatives or other chemical substances. Wolfberry puree can be said to be the essence of wolfberries. It is freshly squeezed into small molecules and is more easily absorbed by the human body. In daily life, the wolfberry puree we can see is made with wolfberries as raw materials and then processed.

[0003] The negative pressure wolfberry puree pressing device makes the inside of the device in a low-pressure state through pump pressure, and then uses the flowing air to squeeze fresh wolfberries, thus completing the pressing of wolfberry puree. The wolfberry puree passes through multiple filter nets inside the device. The last filter net is arranged in the pipeline. The residue left during sieving needs to be regularly disassembled and manually cleaned by the staff, and the human resource cost required during the production process is relatively high. Content of the Utility Model

[0004] The purpose of the utility model is to provide a negative pressure wolfberry puree pressing and sterilizing device to solve the problems put forward in the above background technique.

[0005] To solve the above technical problems, a negative pressure wolfberry puree pressing and sterilizing device provided by the utility model includes a negative pressure device. A Z-shaped pipe is fixedly installed at the bottom of the negative pressure device. A two-way air pump is fixedly installed on the Z-shaped pipe. A filter net is fixedly installed on the Z-shaped pipe. A discharge pipe is connected below the Z-shaped pipe. A spring hinge is fixedly installed at the bottom of the discharge pipe. The discharge pipe is connected with a sealing plate through the spring hinge.

[0006] Further, a one-way valve is fixedly installed on the Z-shaped pipe. The one-way valve is arranged on one side of the discharge pipe. A sealing rubber is integrally formed on one side of the sealing plate.

[0007] Further, a plurality of funnel-shaped filter nets are arranged inside the negative pressure device. An air inlet pipe is fixedly installed at the top of the negative pressure device.

[0008] Further, a sterilization box is arranged above the negative pressure device. A guide pipe is arranged on one side of the sterilization box. A valve is installed at the connection between the sterilization box and the guide pipe. One end of the guide pipe far away from the sterilization box extends into the negative pressure device.

[0009] Further, a steam through pipe is connected to one side of the sterilization box. A condensed water discharge pipe is connected to the bottom of the sterilization box.

[0010] Furthermore, a feed hopper is fixedly installed at the top of the sterilization box, and an inclined filter screen is arranged inside the sterilization box.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, the single-chip microcomputer controls the two-way air pump to apply pressure to the negative pressure device, generating a negative pressure environment in the Z-shaped pipe and the discharge pipe, causing the external air pressure to be higher than the internal pressure, and combining with the force of the spring hinge to seal the discharge pipe.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 3 , the present invention provides a technical solution:

[0022] Refer to Figures 1 - 3 As shown, a negative-pressure wolfberry puree pressing and sterilizing device includes a negative-pressure device 1. A Z-shaped pipe 2 is fixedly installed at the bottom of the negative-pressure device 1. A two-way air pump 4 is fixedly installed on the Z-shaped pipe 2. A filter screen 5 is fixedly installed on the Z-shaped pipe 2. A discharge pipe 3 is connected below the Z-shaped pipe 2. A spring hinge 6 is fixedly installed at the bottom of the discharge pipe 3. The discharge pipe 3 is connected to a sealing plate 7 through the spring hinge 6.

[0023] It should be noted that the two-way air pump 4 is powered by an external power supply.

[0024] Using a single-chip microcomputer to control the two-way air pump 4 to start to generate suction for the negative-pressure device 1, negative pressure will be generated inside the negative-pressure device 1 and the Z-shaped pipe 2. There will be an air pressure difference between the inside of the Z-shaped pipe 2 and the discharge pipe 3 and the outside world. The external high-pressure value is greater than the air pressure value inside the Z-shaped pipe 2 and the discharge pipe 3. The external high air pressure will push the sealing plate 7 against the discharge pipe 3. At the same time, the spring hinge 6 will use elastic force to push the sealing plate 7 against the bottom of the discharge pipe 3. The discharge pipe 3 is relatively small, and there may be some wolfberry puree, but the gravity generated by this weight is less than the elastic force of the spring hinge 6, and the sealing plate 7 will not bounce open.

[0025] After the wolfberries are processed, use a single-chip microcomputer to control the two-way air pump 4 to start. The air between the impeller blades of the two-way air pump 4 rotates in a spiral and accelerates, squeezing and compressing the gas outside the pump body, and finally discharging it through the outlet, thereby generating an air flow. The air flow blows the filter screen 5 in the reverse direction. At the same time, this air flow is sufficient to bounce the sealing plate 7 open, and the air flow makes the impurities break away from the filter screen 5 and discharge from the discharge pipe 3. The above can conveniently and quickly clean the impurities on the filter screen 5 and reduce the expenditure of labor costs.

[0026] Refer to Figures 1 - 2 , a one-way valve 12 is fixedly installed on the Z-shaped pipe 2. The one-way valve 12 is arranged on one side of the discharge pipe 3. A sealing rubber is integrally formed on one side of the sealing plate 7.

[0027] The sealing rubber can significantly improve the sealing performance between the sealing plate 7 and the contact surface, preventing the leakage of liquid or gas during pressing or sterilization. The one-way valve 12 only allows fluid to pass through in one direction, which means that during the pressing process of wolfberry puree, if the internal pressure of the system changes or there are external pressure fluctuations, the one-way valve 12 can prevent the fluid from flowing back into the system.

[0028] See Figure 1 , there are multiple funnel-shaped filters 16 inside the negative pressure device 1, and an air inlet pipe is fixedly installed at the top of the negative pressure device 1.

[0029] During the pressing process of wolfberry puree, the raw materials may contain impurities such as wolfberry skins and seeds. The design of the funnel-shaped filter 16 can effectively filter these impurities, ensuring that the wolfberry puree entering the subsequent process is pure and free of impurities, thereby improving the quality and taste of the product.

[0030] See Figure 1 , there is a sterilization box 13 above the negative pressure device 1, a guide pipe 15 is arranged on one side of the sterilization box 13, a valve is installed at the connection between the sterilization box 13 and the guide pipe 15, and one end of the guide pipe 15 away from the sterilization box 13 extends into the negative pressure device 1.

[0031] The setting of the sterilization box 13 enables the wolfberry puree to directly enter the sterilization stage after pressing without additional transfer process, thereby reducing the risk of contamination.

[0032] See Figure 1 , a steam pipe 14 is connected to one side of the sterilization box 13, and a condensate drain pipe is connected to the bottom of the sterilization box 13.

[0033] The steam pipe 14 allows high-temperature steam to directly enter the sterilization box 13 to efficiently sterilize the wolfberry puree. The high-temperature steam can quickly penetrate the material, effectively killing bacteria, viruses and other microorganisms, ensuring the hygienic quality of the wolfberry puree.

[0034] See Figure 1 , a feed hopper is fixedly installed at the top of the sterilization box 13, and an inclined filter is arranged inside the sterilization box 13.

[0035] The design of the feed hopper enables the wolfberry puree to smoothly enter the sterilization box 13, reducing the splashing and waste of materials during the feeding process, and also helping to keep the production environment clean.

[0036] See Figure 1 , a pressure relief pipe is arranged on the outer wall of the sterilization box 13, and a safety valve is connected between the sterilization box 13 and the pressure relief pipe.

[0037] The main function of the safety valve is to automatically open when the pressure in the sterilization tank 13 abnormally increases, releasing the excess pressure, thereby preventing the sterilization tank 13 from bursting due to overpressure or other safety accidents.

[0038] Refer to Figure 3 , an installation frame 8 is fixedly installed inside the Z-shaped pipe 2, a fan blade 9 is arranged on the installation frame 8, a rotating rod 10 is fixedly installed on one side of the fan blade 9, and a cleaning brush 11 is fixedly installed at the end of the rotating rod 10 away from the fan blade 9, and the cleaning brush 11 abuts against the filter net 5.

[0039] The two-way air pump 4 generates an air flow, which drives the fan blade 9 to rotate. The rotation of the fan blade 9 will drive the rotating rod 10 to rotate, so that the cleaning brush 11 scrapes on the side of the filter net 5 with impurities, further cleaning the impurities on the filter net 5, especially the fine particles stuck in the mesh holes.

[0040] Working principle: The single-chip microcomputer is used to control the two-way air pump 4 to start and generate suction for the negative pressure device 1. Negative pressure will be generated inside the negative pressure device 1 and the Z-shaped pipe 2. There will be an air pressure difference between the inside of the Z-shaped pipe 2 and the discharge pipe 3 and the outside world. The high pressure value outside is greater than the air pressure value inside the Z-shaped pipe 2 and the discharge pipe 3. The external high air pressure will push the sealing plate 7 against the discharge pipe 3. At the same time, the spring hinge 6 will use its elastic force to push the sealing plate 7 against the bottom of the discharge pipe 3. The discharge pipe 3 is relatively small, and there may be some wolfberry puree, but the gravity generated by this weight is less than the elastic force of the spring hinge 6, and the sealing plate 7 will not pop open.

[0041] After the wolfberries are processed, the single-chip microcomputer is used to control the two-way air pump 4 to start. The air between the impeller blades of the two-way air pump 4 rotates in a spiral shape at an accelerated speed, squeezing and compressing the gas outside the pump body, and finally discharging it through the outlet, thereby generating an air flow. The air flow blows the filter net 5 in the reverse direction. At the same time, this air flow is strong enough to pop open the sealing plate 7, and the air flow makes the impurities break away from the filter net 5 and be discharged from the discharge pipe 3. The above can conveniently and quickly clean the impurities on the filter net 5 and reduce the expenditure of labor costs.

[0042] The two-way air pump 4 generates an air flow, which drives the fan blade 9 to rotate. The rotation of the fan blade 9 will drive the rotating rod 10 to rotate, so that the cleaning brush 11 scrapes on the side of the filter net 5 with impurities, further cleaning the impurities on the filter net 5, especially the fine particles stuck in the mesh holes.
