The invention relates to the technical field of cleaning machines, in particular to a trichosanthes kirilowii seed specific gravity type cleaning machine which comprises a machine body, a feeding port is formed in the top of the machine body, a cleaning frame is fixedly connected to the top of the machine body, a vibration motor is installed on the cleaning frame, and multiple layers of cleaning assemblies are arranged in the cleaning frame. The multi-layer cleaning assembly comprises a multi-layer frame, a top-layer filtering frame, a circulating feeding assembly, a long vibrating screen and a short vibrating screen, the multi-layer frame is fixedly connected with the cleaning frame, and the top-layer filtering frame, the long vibrating screen and the short vibrating screen are all fixedly connected with the multi-layer frame; the circulating feeding assembly moves materials in the lower half area of the vibrating short screen to the upper half area of the vibrating short screen through rotation. The technical problems that the stacking height of materials on a vibrating screen is limited by an existing cleaning machine, the material cleaning speed of the vibrating screen is difficult to increase, when the amount of the materials needing to be cleaned is large, waiting for a long time is needed, and the cleaning speed is difficult to increase when the amount of the materials needing to be cleaned is large are solved.

A method of modifying fatty acid profiles of canola (Brassica napus) oil are provided. In some embodiments, the method comprises providing a canola plant having a genetic construct in its genome, the genetic construct comprising coding sequences for Umbellularia californica C12:0 specific acyl-ACP thioesterase and Cinnamomum camphora C14:0 specific acyl-ACP thioesterase operatively linked to seed specific promoters. Also provided are genetically modified canola plants, plant cells, and seeds as well as canola oil extracted therefrom. The canola oils have a balanced fatty acid profile that provides health benefits as well as improved oxidative stability over conventional canola oils.

The utility model discloses an intelligent frequency conversion type seed specific gravity cleaning machine which comprises a cleaning body. And the material uniformizing unit is installed on the upper side surface of the cleaning main body and used for feeding materials to the cleaning main body. According to the seed cleaning device, seeds to be cleaned are injected into the pipe body and can move towards the area of the threaded sheet under the guide of the material distributing plate, then the rotating threaded sheet drives the seeds to move in the pipe body, and meanwhile the pipe body filters the seeds, so that the seeds are uniformly dispersed on the surface of the cleaning main body through the filtering holes; the seed cleaning accuracy can be effectively improved, then the filtering holes can be cleaned through the anti-blocking unit, and the situation that normal operation of the device is affected due to the fact that the filtering holes are blocked is avoided.

The utility model discloses a seed specific gravity screening machine which comprises a device box, a side groove is formed in the side wall of the device box in a penetrating mode, a screening box is arranged in the side groove, the screening box is connected with the inner wall of the device box through a sliding device, and a screening groove is formed in the screening box in a penetrating mode. A feeding pipe is arranged at the inner top of the screening groove in a penetrating mode, the upper end of the feeding pipe is slidably connected to the upper end of the device box in a penetrating mode, a screening device is fixedly connected to the inner wall of the screening groove, and a collecting device is arranged on one side of the device box. The seed separating device has the advantages of being convenient for operators to operate and separate seeds with different specific gravities, simple in structure and worthy of popularization.
