Abstract

The invention discloses a processing technique for cotton seeds, pertaining to the technical filed of seed preparation before planting. Currently, an acid treatment technology is adopted to remove the residual velvet of the cotton seeds, and in order to protect the seeds against damage, strict control can be carried out on the concentration of the acid and the charing temperature of the residual velvet, as the sprouting rate and appearance of the cotton seeds can be affected due to any negligence. Therefore, the invention adds a water spray cleaning device and the working procedures thereof on the basis of the original processing technique. At the same time, the concentration of sulphuric acid in acid treatment solution is increased to 7.0-10.0 percent and the content of a foaming agent and an activating agent is reduced, wherein, the total content of the foaming agent and the activating agent is below 0.35 percent. The invention has the advantages of no residual acid, no residual velvet, lower cost, higher sprouting rate, less damage to the cotton seeds, higher safety and reliability, and glabrous appearance of the cotton seeds.

Description

technical field

[0001] The invention relates to the field of plant cultivation, in particular to the seed preparation process before planting. Background technique

[0002] After the cottonseed is separated from the cotton, there are still a lot of residual lint attached to the surface of the cottonseed. When the seeder sows, because the lint on the surface of the cottonseed is entangled with each other, it hinders the smooth spreading of the seeds from the planter, which seriously affects the quality of the cottonseed. For mechanical sowing, before sowing, the cottonseed must be processed to completely peel off the remaining lint from the surface of the cottonseed. At present, the commonly used process is to use dilute sulfuric acid or foam acid processing process. That is: the sulfuric acid solution stirs the cottonseeds, rubs the cottonseeds with a friction cylinder after being dried by a drying cylinder, and then obtains cotton seeds with a smooth surface and suitable f...

Examples

Embodiment 1

[0024] Embodiment 1 (foam acid technique)

[0025] 1. Measure the cottonseed to be processed;

[0026] 2. Prepare the acid treatment solution, the solution composition is:

[0027] dilute H 2 SO 4 The concentration is 7.0%, foaming agent 0.20%, activator 0.10%;

[0028] 3. Evenly input the cottonseed and acid treatment solution into the mixing tank according to the measurement, and stir for 8 minutes, and it is advisable that the cottonseed fluff is completely soaked;

[0029] 4. Put the acid-treated cottonseed into the drying cylinder, and dry it at 250°C for half an hour, and the remaining velvet will become light seeds after being carbonized;

[0030] 5. Put the dried photoseed into the spray mixer for cleaning, spray with clean water for 2 minutes, the photoseed is stirred and rinsed in a short time, and the excess water flows away through the leak hole at the bottom;

[0031] 6. Transport the cleaned photoseeds to the friction cylinder for drying and rubbing for half...

Embodiment 2

[0033] Embodiment 2 (foam acid technique)

[0034] 1. Measure the cottonseed to be processed;

[0035] 2. Prepare the acid treatment solution, the solution composition is:

[0036] h 2 SO 4 10.0%, foaming agent 0.20%, activator 0.15%;

[0037] 3. Evenly input the cottonseed and acid treatment solution into the mixing tank according to the measurement, and stir for 8 minutes, and it is advisable that the cottonseed fluff is completely soaked;

[0038] 4. Put the acid-treated cottonseed into the drying cylinder, and dry it at 300°C for half an hour, and the remaining velvet on the cottonseed will be carbonized to become light seeds;

[0039] 5. Put the dried photoseed into the friction cylinder and rub for half an hour;

[0040] 6. Put the cottonseed into the spray vibrator for cleaning, spray with clean water for 3 minutes, the light seeds will be rinsed under the vibration in a short time, and the excess water will flow away through the leakage hole at the bottom;

Embodiment 3

[0043] Embodiment 3 (dilute sulfuric acid process)

[0044] 1. Measure the cottonseed to be processed;

[0045] 2. Prepare acid treatment solution, sulfuric acid in the solution: 15%;

[0046] 3. Pour the cottonseed and acid treatment solution into the mixing tank, it is advisable that the seed fluff is completely soaked, and stir for 8 minutes;

[0047] 4. The soaked hair seeds are removed by a centrifuge to remove excess acid.

[0048] 5. Put the acid-treated cottonseed into the drying cylinder, and dry it at 250°C for half an hour. The remaining velvet on the cottonseed is carbonized and becomes light seed;

[0049] 6. Put the light seeds into the spray vibrator for cleaning, spray with clean water for 2 minutes, the light seeds are rinsed under vibration or stirring, and the excess water flows away through the leakage hole at the bottom;

[0050] 7. Put the cleaned photoseed into the rubbing cylinder to dry and rub for half an hour. The temperature of the cottonseed is ...
