Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically to a PLC brine soaking and circulation control system. Background Technology

[0002] Existing technologies have several problems in the brine soaking and circulation process. On the one hand, there is a lack of efficient and flexible devices for controlling the liquid phase discharge during the solid-liquid separation stage. Traditional separation methods struggle to precisely control the liquid phase discharge rate, and when internal pressure changes, they cannot effectively adjust drainage in a timely manner. This can easily lead to increased internal pressure and reverse flow, severely affecting the separation effect. Consequently, impurities in the brine cannot be fully removed, impacting the quality of the brine and subsequent products.

[0003] On the other hand, the overall structural design of the equipment is not reasonable enough, and the installation and disassembly of components are inconvenient, especially key components involving solid-liquid separation devices, such as overflow structures. Maintenance, cleaning, or replacement of these components are complex and consume a lot of manpower and time. In addition, existing technologies are also insufficient in terms of overall temperature control of the brine soaking circulation system and the coordinated operation between units, which cannot meet the needs of modern and refined production and limit the production efficiency and quality stability of braised products.

[0021] 1. This invention utilizes a unique overflow structure to precisely control the liquid phase discharge rate. The overflow component in the overflow structure can adjust the drainage flow rate according to actual conditions. During equipment operation, some liquid can be directly discharged through the drain port by the force of rotation, accelerating the discharge process. Moreover, when the internal pressure is too high, the valve pipe in the overflow component will move under force, squeezing the spring and automatically opening the drain tank to increase the water flow rate and relieve pressure. This effectively avoids reverse flow caused by increased internal pressure, ensuring the high efficiency and stability of solid-liquid separation and improving the quality of the brine.

[0022] 2. The overall structure is ingeniously designed. The overflow housing can be detachably installed inside the main structure. During installation, simply put the overflow housing on the spiral drum, fix it with the second nut, and then install it by matching the upper and lower bottom covers. Disassembly is also relatively simple. This design greatly facilitates the maintenance, cleaning and replacement of parts of the equipment, reduces maintenance costs, and improves the ease of use and service life of the equipment.

[0023] 3. The design of the upper and lower bottom covers increases the volume of the overflow structure installation area. This design improvement effectively prevents the brine from being unable to drain quickly due to insufficient volume during the brine circulation process, even if the internal hydraulic pressure is too high. This ensures the smooth operation of the brine circulation system, provides strong support for the stable progress of the braising process, and helps improve production efficiency and product quality.

[0045] As a preferred embodiment, the main structure 2 further includes a lower bottom cover 21, an upper bottom cover 22, a spiral drum 23, and a second nut 24. The lower bottom cover 21 is a semi-circular concave T-shaped structure, with the diameter of the right end being larger than that of the left end. Several limiting grooves 9 are provided along the upper wall of the lower bottom cover 21 near the left end. A separation disc is provided inside the lower bottom cover 21 near the left end. Solid phase ports and liquid phase ports are provided on the lower walls of both the left and right ends of the lower bottom cover 21. A first insert ring 3 corresponding to the sealing groove 7 is provided inside the lower bottom cover 21 near the right end. The upper bottom cover 22 has the same structure as the lower bottom cover 21, and the upper bottom cover 22... The lower wall is provided with a limiting block 10 corresponding to the limiting groove 9 and a second insert ring corresponding to the first insert ring 3. The upper bottom cover 22 can be disassembled and fastened to the lower bottom cover 21 and is relatively sealed. The spiral drum 23 has a cavity structure and spiral blades are provided on the outer wall of the middle part. A discharge port is provided near the two spiral blades. The two ends of the spiral drum 23 are respectively movably connected through the left and right side walls of the upper bottom cover 22 and the lower bottom cover 21. The right end of the spiral drum 23 is connected to the inner side wall. The second nut 24 can be disassembled and screwed onto the upper right end of the spiral drum 23 and is located inside the right end of the lower bottom cover 21.

[0046] As a preferred option, the overflow housing 11 is movably mounted on the right end of the spiral drum 23 and located inside the right end of the first outer shell.

[0047] As a preferred option, the overflow housing 11 is further fixed by the second nut 24, and the sealing groove 7 is movably fitted onto the first insert ring 3 and the second insert ring.

[0048] As a preferred option, the upper bottom cover 22 and the lower bottom cover 21 are fastened together and can slide alternately.

[0049] Its working principle is as follows:

[0050] After fitting the overflow housing 11 of the overflow structure 1 onto the spiral drum 23 of the main structure 2 and fixing it with the second nut 24, the spiral drum 23 can be inserted into the lower cover 21, so that the overflow housing 11 is located in the lower cover 21 at the larger diameter end; at the same time, the sealing groove 7 of one of the overflow housings 11 is fitted onto the first insert ring 3 of the lower cover 21 and fixed; then the upper cover 22 and the lower cover 21 are staggered so that the limiting block 10 is inserted into the limiting groove 9, and the overflow structure 11 is inserted into the lower cover 21. The sliding mechanism allows the second insert ring inside the upper bottom cover 22 to slide and engage with the first insert ring 3, and then insert it into the sealing groove 7 to complete the engagement. The lower bottom cover 21 is then fixed relative to the upper bottom cover 22. Before installation and use, a hex wrench can be inserted into the hexagonal groove 4 to rotate the adjusting threaded block 143, causing it to move within the manual adjusting tube 142. This, in turn, uses the spring 144 to pull the valve tube 146 on the push rod 145, moving the valve tube 146 within the discharging cylinder 141. The drainage flow rate is adjusted by adjusting the size of the drainage groove 5 on the side wall of the displacement cylinder 141. Furthermore, during use, if the internal separated liquid phase is too large, causing excessive pressure at one end, the valve pipe 146 will move under force, squeezing the spring 144 and opening the drainage groove 5 to increase the water flow rate and relieve pressure. (Note: During the installation of the overflow assembly 14, when the displacement cylinder 141 is fixed by the first nut 147, one side of the drainage groove 5 needs to be aligned with the drain outlet 6). As the overflow structure 1 rotates with the spiral drum 23, a certain amount of liquid discharged through the drainage groove 5 is directly thrown out through the drain outlet 6, further accelerating the discharge flow rate. Simultaneously, the liquid discharged from the drain outlet 6 on the other side of the displacement cylinder 141 will deposit to a certain extent in the space between the two overflow housings 11 that are fastened together by the fastening bolts 12. With rotation, the liquid is driven to rotate by the water-carrying plate 13 fixed in the slot 8, and then thrown out through the drain outlet 6 due to centrifugal force, similarly increasing the discharge flow rate of the separated liquid.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
