Description

Technical Field

[0001] The invention relates to the technical field of donkey-hide gelatin processing, in particular to a fully automatic donkey-hide gelatin rubbing and drying machine. Background Art

[0002] Donkey-hide gelatin is a traditional tonic and blood-replenishing product. It is made from donkey skin as the main raw material and water from the Donkey Well. The best ones are amber in color, transparent, and odorless. They are also called donkey skin gelatin. During the production and drying process of existing donkey-hide gelatin products, the semi-finished gelatin blocks produced will form pollutants such as oil and dirt on the surface. Therefore, they usually need to be polished according to process requirements. Polishing can effectively clean impurities on the surface of the gelatin blocks to ensure the cleanliness of the finished product, while enhancing the light transmittance and color beauty of the donkey-hide gelatin. High-quality donkey-hide gelatin after polishing should meet the characteristics of being as transparent as amber, and the cross-section should be translucent amber in light.

[0003] At present, in the existing donkey-hide gelatin production and processing process, the surface of the donkey-hide gelatin is usually wiped manually, and the six sides of the gelatin block are wiped with wet coarse cloth soaked in hot water. However, the manual operation of wiping the gelatin is cumbersome, labor-intensive, and has low production efficiency. For this reason, we designed an automatic gelatin wiping and drying machine, which can achieve efficient wiping and dry the surface of the donkey-hide gelatin. Summary of the invention
