一种鲜食米饭生产线用蒸煮装置及其生产线

Abstract

本实用新型涉及自热米饭领域内的一种鲜食米饭生产线用蒸煮装置及其生产线，包括煮饭机构、氮气填充机构、翻转输送架、蒸饭机构以及冷却机构；预留有排气孔的饭盒置于煮饭机构内煮饭预定时间后移出，氮气填充机构用于向自煮饭机构移出的饭盒内冲入氮气后进行密封处理，密封处理后的饭盒经翻转输送架后呈倒置，倒置的饭盒经蒸饭机构进行二次熟化后进入冷却机构进行冷却处理。本实用新型通过第一链式传动组件于煮饭箱体内呈连续的波纹形结构设置，使得饭盒随煮饭框上下移动并同时前移过程中，通过类似搅拌的方式使得煮饭箱体内的蒸汽分布更加均匀，自底部与上部的温度的一致性更好，能够有效提高煮饭效果。

Claims

1. A cooking device for a fresh cooked rice production line, characterized by, It includes a rice cooking mechanism (1), a nitrogen filling device (2), a flipping conveyor (3), a rice steaming mechanism (4), and a cooling mechanism (5); The rice cooking mechanism (1) includes a first chain conveyor assembly (11), a rice cooking box (12), and a first steam conveying pipe (13). The rice cooking box (12) is a rectangular box. The first steam conveying pipe (13) is arranged inside the rice cooking box (12). The first chain conveyor assembly (11) located inside the rice cooking box (12) has a corrugated structure design. The rice box housed in the first chain conveyor assembly (11) moves from front to back in the rice cooking box (12) along a corrugated route. The lunch box with a pre-reserved vent is placed in the rice cooking mechanism (1) and cooked for a predetermined time before being removed. The nitrogen filling device (2) is used to inject nitrogen into the lunch box removed from the rice cooking mechanism (1) and then seal it. After being sealed, the lunch box is inverted after passing through the flipping conveyor (3). The inverted lunch box is then cooked a second time by the rice steaming mechanism (4) and then enters the cooling mechanism (5) for cooling.

2. The cooking device for a fresh rice production line according to claim 1, characterized by, The first chain conveyor assembly (11) is mainly composed of a drive sprocket (111), a transmission chain (112), and a rice cooking frame (113). The drive sprocket (111) is installed on the inner walls of both sides of the rice cooking box (12). The drive sprockets (111) on each side of the inner wall of the rice cooking box (12) are staggered vertically. The transmission chain (112) rotatably connected to the drive sprocket (111) has a continuous V-shaped structure. The two sides of the rice cooking frame (113) are hinged to the inner sides of the two transmission chains (112). The rice cooking frame (113) is in a suspended state as it moves with the transmission chain (112) in a V-shaped structure.

3. The cooking device for a fresh rice production line according to claim 2, characterized by, The rice cooking frame (113) is a rectangular frame. The two sides of the length direction of the rice cooking frame (113) are hinged to the inner sides of the two parallel transmission chains (112). The two sides of the width direction of the rice cooking frame (113) are open.

4. The rice cooking apparatus for a fresh cooked rice production line according to claim 1, characterized by The nitrogen filling device (2) includes a nitrogen filling mechanism (21) and a second sealing mechanism (22). The nitrogen filling mechanism (21) is mainly composed of a nitrogen pumping pipe (211) and a nitrogen filling nozzle (212). The inlet end of the nitrogen filling nozzle (212) is connected to the nitrogen pumping pipe (211). The nitrogen filling nozzle (212) is used to fill the lunch box that moves out from the outlet end of the rice cooker (12) with nitrogen. The lunch box filled with nitrogen is sealed by the second sealing mechanism (22).

5. The cooking device for a fresh rice production line according to claim 4, characterized by The second sealing mechanism (22) includes a primary sealing machine (221), a secondary sealing machine (222), and a film flattening machine (223) arranged sequentially from upstream to downstream. After the lunch box filled with nitrogen is sealed by the primary sealing machine (221) and the secondary sealing machine (222) in sequence, the film flattening machine (223) is used to flatten the surface of the secondary sealed lunch box.

6. The rice cooking apparatus for a fresh cooked rice production line according to claim 1, characterized by The flipping conveyor (3) is a C-shaped structure frame. After the lunch box is sealed with nitrogen, it changes from being upright to being upside down after passing through the flipping conveyor (3). The so-called upside down means that the bottom of the lunch box is facing up.

7. The rice cooking apparatus for a fresh cooked rice production line according to claim 1, characterized by The steaming mechanism (4) has the same structural design as the cooking mechanism (1), and the inverted rice box is subjected to secondary cooking treatment at a temperature of 80°C inside the steaming mechanism (4).

8. The cooking device for a fresh rice production line according to claim 1, characterized in that, The cooling mechanism (5) includes a third chain conveyor assembly (51), a cooling box (52), and a spray pipe (53). The third chain conveyor assembly (51) and the first chain conveyor assembly (11) have the same transmission structure design. The third chain conveyor assembly (51) is corrugated inside the cooling box (52). The spray pipe (53) is laid on the top of the cooling box (52). The lunch box undergoing secondary cooking moves in a corrugated shape inside the cooling box (52). The spray pipe (53) sprays ice water to cool the lunch box.

9. A fresh cooked rice production line characterized by comprising: The cooking device for fresh rice production line as described in any one of claims 1-8 is adopted.
