Description

Technical Field

[0001] The invention relates to the technical field of compound jam, in particular to a lemon compound jam and a processing device thereof. Background Art

[0002] There are many kinds of fruits, the area of ​​fruit planting is constantly increasing, and the output is increasing year by year. However, fruits have a short shelf life and are easy to rot and deteriorate, causing huge waste, so it is imperative to develop fruit product processing. Research on the processing of fruit-related products has been carried out worldwide, and fruit jam is one of them. Processing fruits into jam can not only make full use of raw materials, but also be more conducive to product storage, greatly reducing the cost of fresh fruits in the process of storage, transportation, and packaging. Lemon and guava are both fruits with high vitamin C content. Mixing the two fruits into mixed jam can supplement the human body with rich vitamin C, thereby preventing various physical discomforts caused by vitamin C deficiency, such as scurvy, bleeding gums, etc. In recent years, in order to improve the taste and quality of jam (specifically, the quality of color, taste, tissue state, aroma, etc.), the research and development of jam products in my country has been ongoing. On the one hand, considering that the sugar content of jam is relatively high, it may have an impact on the health of consumers. Therefore, low-sugar jam is gaining more and more attention from consumers. On the other hand, the taste of jam is still relatively simple, and consumers often like jam with unique taste. Therefore, how to improve the taste and other qualities of compound jam is also worthy of attention.

[0003] However, in the production process of some existing lemon compound jams, all the production raw materials are often poured into the heating boiler at once. Due to the different types of raw materials, their respective heating energy efficiencies are also different. If all of them are added at once, it will be difficult to mix the raw materials, and even cause the aroma of some raw materials to evaporate in advance, making it difficult to produce a higher grade of lemon compound jam, resulting in a decrease in the user's edible taste. Therefore, there is an urgent need for a lemon compound jam and a processing device thereof to solve such problems. Summary of the invention

[0004] 1. Technical issues to be resolved

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the invention, after the user adds part of the raw materials of the lemon compound jam from the feeding hopper into the mixing barrel (such as Nanguo pear pulp, honey, etc.), adds part of the raw materials of the lemon compound jam into the water tower (such as lemon juice), starts the heater to heat the raw materials of the lemon compound jam in the mixing barrel, and synchronously starts the drive motor to rotate the transmission shaft. Since a stirring plate is fixedly connected to the transmission shaft, the stirring plate will be rotated at this time, and the raw materials of the lemon compound jam can be mixed. When the transmission shaft rotates at a faster speed, the connecting spring will be extended under the action of centrifugal force, and the scraper can scratch out the inner cavity of the mounting plate and fit with the inner wall of the mixing barrel. At this time, the scraper can scrape off the raw materials adhered to the inner wall of the mixing barrel, thereby improving the quality of the whole device for stirring the raw materials of the lemon compound jam.

[0022] 2.

At this time, the return spring is compressed, so that the volume of the upper cavity of the pressure accumulator box increases and the internal liquid pressure decreases. At this time, under the action of the external atmospheric pressure, the lemon juice in the water tower can enter the upper cavity of the pressure accumulator box through the water pipe until the scraper and the piston magnetic plate are separated, and the magnetic attraction of the scraper to the piston magnetic plate is lost. Under the elastic force of the return spring, the piston The magnetic plate will drive the injection tube to move toward the upper part of the inner cavity of the pressure accumulator box, and the volume of the upper cavity of the pressure accumulator box will continue to decrease, and the pressure of the lemon juice inside will continue to increase, and finally it will break through the one-way water valve at the injection tube and spray into the mixing barrel. Therefore, through the above, the device can add part of the raw materials into the mixing barrel in batches for multiple times, which can promote the mixing of the raw materials of the lemon compound jam on the one hand, and avoid the rapid volatilization of the lemon juice due to heat on the other hand, thereby ensuring that the subsequent lemon compound jam has a unique taste and is suitable for users to eat.

[0040] A lemon compound jam processing device comprises a base 1, a mixing barrel 3 is fixedly mounted on the middle of the upper end surface of the base 1 through a bracket 2, a feeding hopper 4 is fixedly mounted on the upper part of the outer wall of the mixing barrel 3, a discharge pipe 5 is arranged on the lower part of the outer wall of the mixing barrel 3, a transmission shaft 6 is rotatably mounted in the middle of the inner cavity of the mixing barrel 3, a mixing mechanism 7 is arranged on the outer wall of the transmission shaft 6, a cleaning mechanism 8 is arranged on the front end surface of the mixing barrel 3, and adding mechanisms 9 are arranged on the front and rear sides of the upper end surface of the mixing barrel 3.

[0041] Furthermore, a driving motor 31 is fixedly installed on the front end surface of the mixing barrel 3 through a frame, and the output shaft end of the driving motor 31 is fixedly installed on the transmission shaft 6 through a coupling. The transmission shaft 6 is set to be hollow. The material of the mixing barrel 3 is transparent heat-insulating material. The mixing mechanism 7 includes a fixed frame 71, a stirring plate 72, a mounting plate 73, a connecting spring 74 and a scraper 75. A fixed frame 71 is fixedly installed on the outer wall of the transmission shaft 6. There are 3 fixed frames 71 in total. Stirring plates 72 are fixedly installed between the fixed frames 71. Mounting plates 73 are fixedly installed on the outer wall of the fixed frame 71. The inner cavity of the mounting plate 73 is slidably connected with a scraper 75. The inner cavity of the mounting plate 73 is fixedly installed with a connecting spring 74. The two ends of the connecting spring 74 are respectively connected to the scraper 75 and the mounting plate 73. The material of the scraper 75 is iron alloy. A heater 32 is provided at the bottom of the inner cavity of the mixing barrel 3.

[0042] It should be noted that after adding some raw materials of the lemon compound jam from the feeding hopper 4 into the mixing barrel 3 (such as Nanguo pear pulp, honey, etc.), some raw materials of the lemon compound jam are added to the water tower 91 (such as lemon juice), the heater 32 is started to heat the raw materials of the lemon compound jam in the mixing barrel 3, and the drive motor 31 is started synchronously to rotate the transmission shaft 6. Since the transmission shaft 6 is fixedly connected with a stirring plate 72, the stirring plate 72 will be rotated at this time, so that the raw materials of the lemon compound jam can be mixed. When the rotation speed of the transmission shaft 6 is faster, under the action of centrifugal force, the connecting spring 74 will be extended, and the scraper 75 can draw out the inner cavity of the mounting plate 73 and fit with the inner wall of the mixing barrel 3. At this time, the scraper 75 can scrape off the raw materials adhered to the inner wall of the mixing barrel 3, thereby improving the quality of the whole device for stirring the raw materials of the lemon compound jam.

[0043] Furthermore, the cleaning mechanism 8 includes a water inlet ring 81, a spray pipe 82 and a connecting pipe 83. The water inlet ring 81 is fixedly installed on the front end face of the mixing barrel 3. The water inlet ring 81 is rotatably installed with the transmission shaft 6. The water inlet ring 81 is connected with the transmission shaft 6. The spray pipe 82 is fixedly installed on the outer wall of the fixed frame 71. The spray pipe 82 is connected with the transmission shaft 6 through the fixed frame 71. A water tank 11 is fixedly installed on the front side of the upper end face of the base 1. A water pump is arranged in the water tank 11. The output end of the water pump is connected with the water inlet ring 81 through the connecting pipe 83.

[0044] It should be noted that, after the raw materials of the lemon compound jam are mixed, the raw materials can be discharged by opening the discharge pipe 5. After the raw materials are mixed, by starting the water pump arranged in the water tank 11, clean water can enter the water inlet ring 81 through the connecting pipe 83. Since the water inlet ring 81 is connected with the transmission shaft 6, the transmission shaft 6 will be filled with clean water. At this time, the driving motor 31 drives the transmission shaft 6 to rotate continuously. Since the spray pipe 82 is connected with the transmission shaft 6 through the fixed frame 71, under the action of centrifugal force and water pressure, clean water can be sprayed on the inner wall of the mixing barrel 3. With the scraper 75, the function of automatically cleaning the inner cavity of the mixing barrel 3 is realized, thereby improving the practicality of the entire device.

[0045] Furthermore, the adding mechanism 9 includes a water tower 91, a water pipe 92, a pressure storage box 93, a piston magnetic plate 94, an injection pipe 95 and a reset spring 96. The water tower 91 is fixedly installed in the middle of the upper side wall of the mixing barrel 3, and the pressure storage box 93 is fixedly installed on the front and rear sides of the upper side wall of the mixing barrel 3. The water tower 91 is connected to the pressure storage box 93 through the water pipe 92. The inner cavity of the water pipe 92 is provided with a one-way water valve whose outlet is to the inner cavity of the pressure storage box 93. The inner cavity of the pressure storage box 93 is slidably installed with a piston magnetic plate 94. The inner cavity of the piston magnetic plate 94 is fixedly installed with an injection pipe 95. A reset spring 96 is wound around the side wall of the injection pipe 95. The two ends of the reset spring 96 are respectively connected to the piston magnetic plate 94 and the side wall of the pressure storage box 93. The inner cavity of the injection pipe 95 is provided with a one-way water valve whose outlet is to the outside. The injection pipe 95 is connected with the pressure storage box 93 and the mixing barrel 3 through.

[0046] It should be noted that when the scraper 75 rotates, since the scraper 75 is made of iron alloy, when the scraper 75 and the piston magnetic plate 94 are close to each other, it can attract the piston magnetic plate 94 to move toward the lower part of the inner cavity of the pressure accumulator box 93. At this time, the return spring 96 is compressed, so that the upper cavity volume of the pressure accumulator box 93 increases and the internal liquid pressure decreases. At this time, under the action of the external atmospheric pressure, the lemon juice in the water tower 91 can enter the upper cavity of the pressure accumulator box 93 through the water pipe 92, until the scraper 75 and the piston magnetic plate 94 are separated, the magnetic attraction of the scraper 75 to the piston magnetic plate 94 is lost, and under the elastic force of the return spring 96, the piston magnetic plate 94 will drive the injection pipe 95 to move toward the upper part of the inner cavity of the pressure accumulator box 93, and then the upper cavity volume of the pressure accumulator box 93 is continuously reduced, and the internal lemon juice pressure is continuously increased, and finally it can break through the one-way water valve at the injection pipe 95 and spray into the mixing barrel 3.

[0047] Working principle:

[0048] After adding some raw materials of lemon compound jam from the feeding hopper 4 into the mixing barrel 3 (such as pear pulp, honey, etc.), adding some raw materials of lemon compound jam into the water tower 91 (such as lemon juice), starting the heater 32 to heat the raw materials of lemon compound jam in the mixing barrel 3, and synchronously starting the driving motor 31 to rotate the transmission shaft 6. Since the transmission shaft 6 is fixedly connected with the stirring plate 72, the stirring plate 72 will be rotated at this time, so that the raw materials of the lemon compound jam can be mixed. When the speed of the transmission shaft 6 is fast, under the action of centrifugal force, the connecting spring 74 will be extended, and the scraper 75 can draw out the inner cavity of the mounting plate 73 and fit with the inner wall of the mixing barrel 3. At this time, the scraper 75 can scrape off the raw materials adhered to the inner wall of the mixing barrel 3, thereby improving the quality of the whole device for stirring the raw materials of the lemon compound jam;

[0049] When the scraper 75 rotates, since the scraper 75 is made of iron alloy, when the scraper 75 and the piston magnetic plate 94 are close to each other, it can attract the piston magnetic plate 94 to move toward the lower part of the inner cavity of the pressure accumulator box 93. At this time, the return spring 96 is compressed, so that the upper cavity volume of the pressure accumulator box 93 increases and the internal liquid pressure decreases. At this time, under the action of the external atmospheric pressure, the lemon juice in the water tower 91 can enter the upper cavity of the pressure accumulator box 93 through the water pipe 92, until the scraper 75 and the piston magnetic plate 94 are far away from each other, the magnetic attraction of the scraper 75 to the piston magnetic plate 94 is lost, and the return spring 96 is elastic. Under the action of force, the piston magnetic plate 94 will drive the injection tube 95 to move toward the upper part of the inner cavity of the pressure accumulation box 93, and then the volume of the upper cavity of the pressure accumulation box 93 will continue to decrease, and the pressure of the lemon juice inside will continue to increase, and finally it will break through the one-way water valve at the injection tube 95 and spray into the mixing barrel 3. Therefore, through the above, the device can add part of the raw materials into the mixing barrel 3 in batches for multiple times, which can promote the mixing of the various raw materials of the lemon compound jam on the one hand, and avoid the rapid volatilization of the lemon juice due to heat on the other hand, thereby ensuring that the subsequent lemon compound jam has a unique taste and is suitable for users to eat.

[0050] When the raw materials of the lemon compound jam are mixed, the raw materials can be discharged by opening the discharge pipe 5. After the raw materials are mixed, by starting the water pump arranged in the water tank 11, clean water can enter the water inlet ring 81 through the connecting pipe 83. Since the water inlet ring 81 is connected with the transmission shaft 6, the transmission shaft 6 will be filled with clean water. At this time, the driving motor 31 drives the transmission shaft 6 to rotate continuously. Since the spray pipe 82 is connected with the transmission shaft 6 through the fixed frame 71, the clean water can be sprayed on the inner wall of the mixing barrel 3 under the action of centrifugal force and water pressure. With the scraper 75, the function of automatically cleaning the inner cavity of the mixing barrel 3 is realized, thereby improving the practicality of the entire device.

[0051] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
