Detailed Description

For the purposes of example embodiments, technical solutions and advantages of the present invention, the following description will be made in further detail with reference to the accompanying drawings and detailed description.

A vertical rice steamer and a rice steaming method as recited in fig. 1 to 3, comprising: a rice steamer body comprising a rice steamer 15 provided with a feed port 14 and a rice outlet 5, a circulating conveying device and a heating device inside the rice steamer; the feeding device comprises a wet rice discharging bin 1 positioned outside the rice steaming box body and a metering device 2 positioned at the outlet of the wet rice discharging bin. The feeding device stores wet rice through the wet rice discharging bin, and quantitatively adds quantitative wet rice to the rice basin at the position corresponding to the feeding opening of the rice steaming box through the metering device. After the wet rice is added, the rice basin is transported clockwise by the annular conveying device. The hot steam in the wall pipe 9 provided by the heating device 13 is indirectly heated and the hot steam in the lower part of the box body is directly heated during the transportation of the rice basin. After the cooked rice is cooked, the cooked rice is transported to a rice discharging mechanism clockwise by an annular conveying chain. The meal outlet mechanism is used for completing tilting and vibration discharging of the meal basin. The rice steamer of this scheme can realize adding material-steamed rice-ejection of compact automation and accomplish, has advantages such as novel structure, convenient operation.

According to the vertical rice steaming machine and the rice steaming method, automatic large-batch rice steaming is achieved, continuous rice output can be achieved, the workload of manually conveying wet rice is reduced, production limitation of unified rice steaming and unified discharging is broken, and operation is convenient. Solves the problems that the existing rice steaming cabinet needs to carry wet rice manually and can only cook rice in the cabinet uniformly and discharge the rice uniformly. Pouring and discharging after steaming can directly put the rice basin into secondary steaming and boiling, and meanwhile, the rice can be conveniently separated.

As shown in fig. 1, the circulating conveying device is an annular conveying device, and a meal outlet mechanism is arranged at the tail end of the rising section and is positioned above a meal outlet of the rice steaming box. The annular conveying device carries out cyclic conveying on the positions of the feeding, heating and discharging functions of the rice basin. The meal discharging mechanism solves the problem that the cooked meal needs to be manually dumped into the meal distributing device, has high transportation efficiency, saves labor cost, and ensures the operation safety of staff due to an automatic and closed structure.

As shown in fig. 1, the feeding device comprises a wet rice discharging bin 1 positioned outside the rice steaming box body and a metering device 2 positioned at the outlet of the wet rice discharging bin.

As shown in fig. 1, the rice-discharging mechanism comprises an upper reset guide wheel 18, a lower rice-discharging guide wheel 19 and a conveying chain at the position around the two guide wheels. The conveying chain is wound around the conveying wheel to form an S shape, and the rotary hanging arm of the rice steaming machine moves along the conveying chain. The rice outlet guide wheel and the inclined baffle 6 enable the rotary hanging arm of the rice steamer to rotate 90 degrees, and the reset guide wheel enables the rotary hanging arm of the rice steamer to reset under the action of gravity.

As shown in fig. 1, an inclined baffle plate and a linear vibrator 4 fixed below the inclined baffle plate are arranged below the rice guide wheel. The rotary hanging arm of the rice steamer and the rice basin are rotated by 90 degrees to pour out the rice by blocking the inclined baffle plate. The linear vibrator transmits vibration to the rice basin through the inclined baffle plate, so that the rice basin vibrates to completely pour out the residual rice in the rice basin.

As shown in fig. 1 and 4, the conveyor chain 17 fixes the rice steamer rotary hanging arm 10 at intervals by the connector 12. The rotary hanging arm of the rice steaming machine is a triangle hook with an opening. One end of the triangular hook opening is a circular hole and is fixed on the conveying chain through a connector. The connector ensures that the rotary hanging arm of the rice steamer does not interfere when finishing the dumping function, and reduces the vibration transmitted to the annular conveying device by the linear vibrator.

As shown in fig. 1 and 3, the heating device heats the rice pot on the upper conveying chain by directly supplying heat to the wall pipe 9 and steam. The steam indirectly heats the lower part of the rice steaming box through the wall pipe, so that the transmission efficiency of steam heat is improved. The heat transfer efficiency of the rice basin below the conveying chain is improved when the steam directly supplies heat, so that the rice can be steamed. The heating device 13 is placed in the rice steaming box heat preservation layer 16, and heat is guaranteed to be upwards transmitted to the greatest extent.

As shown in fig. 1, the bottom of the heat-insulating layer 16 is adhered to the wall and the bottom of the box, the top 8 of the heat-insulating layer is conical, and a channel for the rotary hanging arm 10 of the rice steamer is reserved on the inclined surface. The bottom of the heat preservation layer improves the upward heat transmission efficiency of the heating equipment. The conical top makes steam condensate flow down along the wall of the rice steaming machine box, so that the steaming efficiency of the lower machine box of the rice steaming machine is improved.

As shown in fig. 1, the wet rice discharging bin is positioned above the rice steaming box material adding port, and the arc-shaped cover plate above the rice steaming box can be opened. The outlet of the wet rice discharging bin is corresponding to the feeding hole of the rice basin, and the wet rice can be directly poured into the rice basin at the feeding hole by utilizing gravity, and the total amount of the poured wet rice is controlled by controlling the outlet of the wet rice discharging bin through a metering device.

Next, a specific procedure of a rice steaming method realized based on the rice-discharging mechanism will be explained. The rice steaming method comprises the following steps:

s1, adding wet rice into corresponding rice basins of a rice steamer through a metering device by an external material adding device, and continuously adding rice into different rice basins through a circulating conveying device;

s2: before the circulating conveying device conveys the rice basin to the rice outlet mechanism, the heating device continuously heats the rice basin, the rotary hanging arm of the rice steaming machine rotates by 60-120 degrees under the action of the rice pouring guide wheel and the inclined baffle, and the inclined baffle drives the linear vibrator to vibrate until the rice basin shakes off rice

S3: the rotary hanging arm of the rice steamer resets under the action of the resetting guide wheel and gravity.

Specifically, the rice is transported to a rice outlet mechanism by an annular conveying device in the cooking process, and the rice is cooked before the rice outlet mechanism. The inclined baffle and the rice outlet guide wheel of the rice outlet mechanism limit the rotary hanging arm of the rice basin and the rotary hanging arm of the rice steamer respectively, and meanwhile, the annular conveying device still keeps moving, and the rice basin and the rotary hanging arm start to rotate to 90 degrees.

Then, the linear vibrator starts vibrating and drives to the rice basin through the inclined baffle so that rice can shake off better until the rotary hanging arm of the rice steaming machine is continuously transported to the inclined baffle and the rice outlet guide wheel by the annular conveying device and cannot limit the rice basin and the rotary hanging arm of the rice steaming machine.

Then, the rice basin and the rotary hanging arm naturally recover to the original positions under the action of gravity and the reset guide wheel.

The foregoing is merely illustrative embodiments of the present invention, and the present invention is not limited thereto, and any person skilled in the art, which is disclosed herein, may make equivalent substitutions or modifications according to the technical solution and the inventive concept thereof, and thus should be covered by the scope of the present invention.
