Embodiment 1

[0034] see Figure 1-2 , a device for removing husks and seeds of Tilia Nanjing with liquid nitrogen, adopts an integrated design, so that the treatment of husks and seeds of Tilia Nanjing can be completed in the device, including a processing container 1, a waste husk collection bucket 14 and a drying platform 17 , the processing container 1 is used to remove the husk of Tilia Nanjing and washes and separates the seeds. The seed kernels of Nanjing Tilia are dried in the shade;

[0035] The top of the processing container 1 is provided with a feed inlet 2, a control panel 3 is fixedly installed on one side of the top of the processing container 1, and a lifting mechanism 10 is fixedly installed on both sides of the inside of the processing container 1. The mechanism 10 is controlled by the control panel 3, the first upper screen 5 and the first lower screen 6 are slidably connected to the lifting mechanism 10, the first upper screen 5 and the first lower screen 6 A second up...

Embodiment 2

[0042] A kind of operation method of liquid nitrogen removal Nanjing linden husk separation seed, operates based on a kind of device in embodiment 1 that liquid nitrogen removes Nanjing linden husk separation seed, comprises the following specific steps:

[0043] S1, pour Nanjing linden seeds into feed port 2, Nanjing linden seeds are poured into treatment container 1 and screened through the first upper screen 5 and the first lower screen 6 to screen out large seeds and small seeds;

[0044] S2. Use the lifting mechanism 10 to control the first upper screen 5, the first lower screen 6, the second upper screen 7 and the second lower screen 8 to descend, and use liquid nitrogen for quick freezing for 40 seconds, and the lifting mechanism 10 controls The first upper screen cloth 5, the first lower screen cloth 6 and the second upper screen cloth 7 and the second lower screen cloth 8 return to the initial position;

[0045] S3. Nanjing linden seeds are screened by the first upper...

Abstract

The invention discloses a device for removing tilia miqueliana shells and separating seeds by liquid nitrogen and an operation method of the device, belongs to the technical field of tilia miqueliana planting, and adopts an integrated design, so that treatment of the tilia miqueliana shells and seeds is completed in the device, and the device comprises a treatment container, a waste shell collecting barrel and a shade drying platform, wherein the treatment container is used for removing shells of tilia miqueliana and washing the tilia miqueliana with water to separate seeds, the waste shell collecting barrel is used for collecting the removed shells of tilia miqueliana, and the shade-drying platform is used for carrying out shade-drying treatment on separated kernels of tilia miqueliana; then liquid nitrogen enters the treatment container in an injection mode, cell structures of the shells are destroyed through the liquid nitrogen quick-freezing and ultralow-temperature freezing and thawing effects, the biological mechanical force at the joints of the shells and the core and the skin is reduced, and therefore the purpose of quickly removing the shells is achieved, and complete kernels in the shells cannot be damaged through ultralow-temperature treatment within a short time; and the seed kernels can hold a high plumpness rate.

Description

technical field [0001] The invention belongs to the technical field of Nanjing linden planting, and specifically relates to a device for removing husk and separated seeds of Nanjing linden with liquid nitrogen and an operation method thereof. Background technique [0002] Nanjing linden leaves have strong shade and fragrant flowers. They are excellent urban and rural greening trees and can be used as street trees, square greening and garden greening. Nanjing linden wood is white, light and soft, and can be used for construction, furniture, papermaking, carving, joinery and other materials. The bast fiber is developed, commonly known as "bass hemp", which can be used for artificial cotton, rope and weaving. It is also an excellent nectar source for brewing high-grade honey; Nanjing linden flower and bark can be used as medicine, and its infusion has the effects of sedation, sweating, antispasmodic and antipyretic; stem bark contains tannin, fat, wax and pectin, etc. It is u...
