Technical Field
[0001] The present application relates to the technical field of food processing, and in particular to a device for processing blanching-free frozen instant beans. Background Art
[0002] The blanching-free frozen instant bean product uses high-temperature steam to instantly penetrate the beans, achieving rapid greening and preliminary ripening to retain the natural color and taste of the beans; the beans are then rapidly cooled to an ultra-low temperature to ensure that the moisture in them forms tiny ice crystals, thereby maintaining the integrity of the beans' cell structure; the beans made in this way not only retain the natural deliciousness and nutritional value of the beans, but also have the characteristics of convenience and health, becoming a new favorite on the tables of modern consumers.
[0003] In the process of heating beans, the beans are usually poured into a heating tank, and then high-temperature steam is used to heat the beans until they are cooked; however, if the beans are heated unevenly during heating, some areas may be overcooked while other areas are not fully cooked, which not only affects the overall taste of the beans, but also requires additional screening and rework to remove undercooked or overcooked beans, affecting production efficiency. Therefore, a processing device is needed to improve the uniformity of bean heating. Utility Model Content

[0018] Optionally, the top wall of the heating tank is provided with an exhaust pipe, the inner wall of the exhaust pipe is provided with a condensation plate, and the heating tank is provided with a water collecting tank connected to the exhaust tank.
[0019] By adopting the above technical solution, when the steam inside the heating tank is discharged to the outside through the exhaust pipe, the condensation plate can condense it into liquid and flow it into the water collecting tank, thereby reducing the situation where the steam is directly discharged to the outside and causes burns to the staff.

[0024] 2. By setting up an exhaust pipe, the steam inside the heating tank is discharged to the outside through the exhaust pipe. The condensation plate can condense it into liquid and flow it into the water collecting tank, thereby reducing the possibility of scalding to the staff caused by direct discharge of steam to the outside.

[0033] A motor 23 is installed on the outer wall of one end of the heating tank 2, and a first gear 24 is fixed to the output shaft of the motor 23. The stirring structure 3 is provided with a second gear 25, and the first gear 24 and the second gear 25 are meshed. Starting the motor 23 can make the stirring structure 3 rotate in the stirring tank to stir the beans.
[0034] An exhaust pipe 4 is arranged on the top of the heating tank 2. A bending pipe 41 is integrally formed at one end of the exhaust pipe 4 away from the heating tank 2. The bending pipe 41 is arranged to be inclined downward, and a condensation plate is arranged inside the bending pipe 41. A water collecting tank 42 is arranged on the outer wall of the heating tank 2, and the bending pipe 41 is connected to the water collecting tank 42.
[0035] When the steam inside the heating tank 2 is discharged to the outside through the exhaust pipe 4, the condensation plate can condense it into liquid and flow it into the water collecting tank 42, thereby reducing the situation where the steam is directly discharged to the outside and causes burns to the staff; and the downward inclined setting of the bending pipe 41 can reduce the situation where the condensed water returns to the inside of the heating tank 2 through the exhaust pipe 4.
