Description

Technical Field

[0001] The present invention relates to the technical field of cheese extrusion molding, and in particular to cheese extrusion molding equipment and a molding process with intelligent temperature control. Background Art

[0002] Cheese is a dairy product made through a fermentation and coagulation process. Its concentration is higher than that of yogurt and is similar to that of solid food. Cheese is rich in nutrients such as protein, calcium, fat, phosphorus and vitamins. After removing the whey, cheese needs to be extruded and formed. During the extrusion process, attention must be paid to temperature control to avoid temperature affecting the molding effect and nutrient loss. In this process, factors such as water evaporation must also be controlled. Secondly, the toughness of cheese molding is also affected by the temperature generated during processing. Therefore, precise processing is required in the temperature change range between melting and setting. The existing technology usually manually extrudes cheese, which is labor-intensive and will result in uneven size of the extruded cheese blocks and different toughness of the cheese. When manually extruded, unformed cheese is easy to stick to the hands, resulting in material loss during processing. Summary of the Invention

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention adopts intelligent temperature control technology to realize temperature control during the cheese extrusion molding process. When the cheese reaches a predetermined temperature range, the discharge port is automatically opened, so that the cheese is extruded and molded under ideal temperature conditions. When the cheese temperature exceeds the predetermined temperature range, the discharge port is automatically closed to ensure that the temperature of the extruded cheese is within the predetermined range, thereby ensuring that the surface of the extruded cheese is smooth, the structure is stable, and it has good toughness during molding, effectively avoiding defects such as molding failure, adhesion, and breakage.

[0031] 2. The present invention adopts anti-sticking technology to solve the problem that cheese is prone to sticking to the surface of the pressing plate due to high temperature and high pressure during the extrusion molding process. When the extrusion pressure is the highest and sticking is likely to occur, cooling water is quickly introduced into the interior of the pressing plate to cool the interior of the pressing plate, reduce the temperature of the pressing plate surface, and quickly solidify the surface of the cheese in the contact area to form a stable protective film, thereby reducing the adhesion between the cheese and the pressing plate, improving the integrity and smoothness of the cheese surface, extending the service life of the equipment, and reducing the frequency of cleaning and maintenance;

[0032] 3. The present invention adopts a purely mechanical design. The sensor is prone to inaccurate detection in a high-temperature environment. The use of a purely mechanical design can stably complete various processes in the extrusion molding process. The purely mechanical design has a simple structure and a quick response, which improves the reliability and service life of the overall operation of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0071] Working principle of the present invention:

[0072] During use, the mold is manually placed on the conveyor belt 2, and the control system controls the conveyor belt 2 to start. The conveyor belt 2 transports the mold to the bottom of the discharge port 45, controls the discharge valve to open, and the heat-conducting oil in the spiral tube 43 heats the raw materials inside the heating box 42. When the temperature in the heating box 42 rises, the bimetallic strip 4421 bends due to the heat, and the bimetallic strip 4421 drives the short plate 4422 to move downward.

The memory alloy 4435 then drives the second lever 4434 to rotate around the cylinder. The second lever 4434 drives the long plate 4427 to rise. The long plate 4427 drives the limiting plate 4425 and the rack 4428 to rise. The rack 4428 drives the gear 4431 to rotate. The gear 4431 drives the first rotating shaft to rotate.

[0074] When the temperature in the heating box 42 drops to a predetermined range, the memory alloy 4435 is retracted and first drives the lever 4433 to rotate. The lever 4433 drives the second pawl to disengage from the ratchet 4432. The lever 4433 drives the first pawl to rest on the ratchet 4432. The memory alloy 4435 then drives the second lever 4434 to rotate around the cylinder. The second lever 4434 drives the long plate 4427 to descend. The long plate 4427 drives the limit plate 4425 and the rack 4428 to descend. The rack 4428 drives the gear 4431 to rotate. The gear 4431 drives the first rotating shaft to rotate.

[0075] When the raw material in the mold is filled, the conveyor belt 2 is controlled to transport the mold to the bottom of the pressure plate 532, and the cylinder rod of the hydraulic cylinder 52 is controlled to extend. The cylinder rod drives the extrusion rod 531 to descend, and the extrusion rod 531 drives the pressure plate 532 to descend. The pressure plate 532 presses on the raw material in the mold. The raw material pushes the detection plate 535 to rise, and the detection plate 535 drives the detection rod 533 to rise. The detection rod 533 drives the water inlet tray 534, the drainage fan 537 and the connecting plate 536 to rise. When the extrusion pressure is maximum, the connecting plate 536 is located at the first limit plate. At this time, the detection plate 535 and the detection plate 535 are aligned. The lower plane of the pressing plate 532 is flush, the water inlet tray 534 leaves the pressing plate 532, and the cooling water in the cooling water tank enters the extrusion rod 531 from the water inlet pipe 538. The cooling water enters the pressing plate 532 from the extrusion rod 531, cooling the inside of the pressing plate 532, reducing the temperature of the surface of the pressing plate 532, and making the surface of the cheese in the contact area solidify quickly to form a stable protective film.
