Description

Technical Field

[0001] The invention relates to the technical field of soaked duck feet processing, in particular to novel energy-saving soaked duck feet pasteurization and disinfection equipment and process. Background Art

[0002] The pasteurization and disinfection equipment for soaked duck feet involves the disinfection process in food processing. Pasteurization is a mild heat treatment method, which is often used in food processing to kill harmful microorganisms while trying to maintain the nutritional value and flavor of the food. For ingredients such as soaked duck feet, pasteurization can ensure its safety. The pasteurization and disinfection equipment for soaked duck feet usually refers to the equipment used to pasteurize duck feet. Pasteurization is a common food processing technology, which is mainly used to kill harmful bacteria that may exist in food to extend the shelf life of food.

[0003] At present, the horizontal sterilizing kettles used in the market use high temperatures of 105°C to 107°C to ensure the sterilization effect during the food sterilization process. However, the processing capacity of traditional sterilizing kettles is limited. The sterilization time for each pot of product is about 30 minutes. Considering that each pot can store 5 tons of hot water, 36 pots are required to process a total of 720,000 packages of products per day. The existing configuration is two sterilizing kettles operating in parallel to meet daily production needs. These two sterilizing kettles need to work continuously for 10 hours a day, with a sterilization efficiency of 72,000 packages per hour. This production model still has many problems. The first is high energy consumption. On the one hand, the energy consumption is high due to the large amount of hot water used. On the other hand, the product will be affected by the high sterilization temperature. The crispness and taste will be affected. Secondly, due to the use of segmented production, the product needs to be manually transported, which leads to further increases in labor costs and production efficiency.

[0004] In view of this, the present invention solves the above technical problems by proposing a new energy-saving soaked duck feet pasteurization and disinfection equipment and process. Summary of the invention

[0005] In view of the shortcomings of the above-mentioned background technology, the present invention provides a technical solution of a novel energy-saving pasteurization and disinfection equipment and process for soaked duck feet. First, the sterilization temperature is controlled at 93°C-95°C. Compared with the traditional high-temperature treatment of 105°C to 107°C, the sterilization time is significantly shortened. The heating rod arranged at the bottom of the inner cavity of the sterilization tank can heat the water quickly and evenly, ensuring the sterilization effect while reducing energy consumption. At the same time, a mild pasteurization process of 93°C-95°C is adopted to effectively kill harmful microorganisms while retaining the nutritional value and flavor of soaked duck feet to the maximum extent, avoiding the problem of deterioration of taste caused by high-temperature treatment. Secondly, the material is automatically transported by a chain transmission mechanism without manual intervention, thus avoiding the inefficiency problem caused by segmented production. 72,000 packages of products can be processed per hour, and only 10 hours of continuous work is needed to meet the daily production demand of 720,000 packages, thereby significantly improving production efficiency.

The use process of the new energy-saving soaked duck feet pasteurization and disinfection equipment is characterized in that: According to the new energy-saving soaked duck feet pasteurization and disinfection equipment according to any one of claims 1-8, the specific method comprises the following steps; S1, inject 10 tons of hot water into the sterilization pool (1), inject 5 tons of circulating cooling water into each of the two cooling pools (101), and operate the control panel (702) to reset the collection frame (202) to a parallel state with the sterilization pool side; S2, the driving motor (8) is started, and the empty material frame (408) is transferred to the loading station via the sliding plate (405) through the rotating shaft (401)-sprocket (402)-chain (403) transmission system; S3, the conveyor belt in the inner packaging workshop transports the material to be sterilized to the material frame (408), the control panel sets the constant temperature range of the heating rod (7) to 93-95°C, and the second electric push rod (407) drives the material frame to immerse in the sterilization tank for 15-20 minutes; S4, the material frame (408) is transferred to one of the cooling pools (101), and the second electric push rod (407) drives the immersion cooling for 5 minutes, and the air pipe is started synchronously: compressed air is injected into the ventilation pipe (5) through the electromagnetic air valve at a pressure of 0.2MPa, and the bubble frequency is 30 times / min; S5, the material frame (408) is transferred to another cooling pool (101) and immersed in cooling for 5 minutes; S6, the cooled material frame (408) is transferred to the unloading station and enters the aseptic packaging area via a conveyor belt; S7, the driving motor (8) drives the threaded rod (206) to rotate, and the guide rod (207) guides the collection frame (202) to move along the pool surface. When the collected sewage volume reaches 80% of the volume, the cylinder (302) drives the locking block (301) to unlock the first electric push rod (205) to perform a 135° flipping and throwing action.
